- Abstract
-
-
-
- This paper examines the effectiveness of the DARE (Drug Abuse Resistance
- Education) program in Charleston County, South Carolina by comparing 341
- fifth grade DARE students to 367 nonDARE students. Significant differences
- were found in the predicted direction for alcohol use in the last year,
- belief in prosocial norms, association with drug using peers, positive peer
- association, attitudes against substance use, and assertiveness. No
- differences were found on cigarette, tobacco, or marijuana use in the last
- year, frequency of any drug use in the past month, attitudes about police,
- coping strategies, attachment and commitment to school, rebellious
- behavior, and self-esteem.

- I. INTRODUCTION
-
- The adolescent drug use epidemic in the United States dates back over
- 20 years. Beginning in the 1960's when much of the nation's youth began
- to use psychoactive drugs such as LSD and PCP, the drug epidemic created
- public concern as it continued into the 70's. The 1980's showed much of
- the same with drug use on the rise and new drugs such as MDMA (XTC), ice,
- and crack suddenly appearing in every major city.
-
- This paper begins with an examination of the adolescent drug use
- problem in the United States and Charleston, South Carolina (where the
- current study takes place). Possible solutions to this problem are
- briefly discussed and a summary of prior studies of Drug Abuse Resistance
- Education (DARE) is provided. The current study is then presented followed
- by a brief discussion and recommendations for future research.
-
- Much of what is known about adolescent drug use is a result of the
- annual High School Senior Survey conducted by the Institute for Social
- Research at the University of Michigan (Johnston, 1973). Data from a
- recent report examining drug use (Johnston, Bachman, & O'Malley, 1991) show
- a gradual decline for all types of drugs since 1975. However, the current
- levels of drug use in the United States imply a large number of adolescents
- are still using drugs. For example, in 1990, 90 percent of U.S. seniors
- reported drinking alcohol at some time in their lives, while 64 percent
- said they had smoked cigarettes.
-
- Adolescent drug use in Charleston, South Carolina, where the current
- study takes place, is similar to national use.
-
- During the 1989-90 school year all students (223,663) in grades 7-12
- in South Carolina's 91 public school districts were surveyed to collect a
- variety of information on current and past drug use (South Carolina
- Department of Education and South Carolina Commission on Alcohol and Drug
- Abuse, 1990). Many of the survey questions were modeled after the annual
- High School Senior Survey (Johnston, 1973).
-
- The main findings for grade 12 from the South Carolina survey for
- Charleston County are presented in Table 1. Relevant national data are
- also shown for comparison. Information collected from the Charleston
- survey includes lifetime, annual, and 30-day prevalence rates.
-
- Lifetime prevalence rates show the U.S. percentages generally larger
- than those in Charleston. For example, almost 90% of the U.S. seniors
- compared to 77% of the Charleston seniors said they had drunk alcohol at
- least once in their lives. In addition, 10% more U.S. seniors than
- Charleston seniors said they had used marijuana and 17% more U.S.seniors
- said they had smoked cigarettes.
-
- In contrast to the lifetime prevalence rates, the 30-day prevalence
- rates for Charleston and the U.S. are quite similar. Very small
- differences exist with about half favoring the U.S. and half favoring
- Charleston.
-
- The South Carolina and National Youth Survey data give a useful picture
- of the extent of drug use in the United States and Charleston, South
- Carolina. However, it should be noted that many youths leave school before
- their senior year. Obviously, the youths who have dropped out of school
- before their senior year are not included in either the annual High School
- Senior Survey or the South Carolina Youth Survey. Since drug use is higher
- for high school drop outs than it is for those who stay in-school (Anhalt &
- Klein 1976; Johnston, 1973) reported senior drug use rates are most likely
- underestimates for all adolescents.
-
- Even with dropouts excluded from the survey data, the amount of
- reported drug use in the United States, and Charleston, South Carolina,
- is high. Although national data show reported drug involvement slowly
- declining, the current high levels of drug use display a grim picture of
- adolescents today. Furthermore, the drug epidemic is far from over and the
- goal of drug free youth in America is still very distant. Answers to the
- question of what can be done to stop the drug use epidemic still escapes
- practitioners, law enforcement personnel, health professionals and social
- scientists.
-
- The past two decades have led to a variety of strategies aimed at
- combatting the drug problem. Polich, Ellickson, Reuter, & Kahan (1984)
- suggest the three most widely used attempts to combat or control drug use
- are supply reduction, treatment, and prevention.
-
-
- Supply Reduction
-
- Efforts to limit or control the supplies of drugs have been carried out
- via laws unfavorable towards drug use and corresponding law enforcement
- activities. Law enforcement agencies have directed efforts at reducing the
- production, import, distribution, and retail sales of illegal "street"
- drugs. The hope remains that by targeting these major market areas the
- quantity of drugs entering the country will decrease, trafficking and
- selling drugs will become more risky, shortages of drugs in the illicit
- market will take place, and the price of drugs to consumers will increase,
- ultimately reducing consumption.
-
- As Hawkins, Catalano, and Miller (1992) point out, manipulating illegal
- drug supplies by increasing drug interdiction and drug dealer arrests should
- lead to positive outcomes such as raising the price of street drugs to the
- user, thus reducing the demand for drugs.
-
- However, contrary evidence is cited by Polich, et al. (1984). They
- conclude doubling drug interdiction, and/or increasing arrests and
- imprisonment of drug dealers would affect neither retail prices nor the
- availability of illegal drugs. Essentially, the point is made that large
- drug quantities will always be available to take the place of any quantity
- confiscated. Increasing arrests would do little, they argue, because prison
- overcrowding forces the least violent to become paroled and often times
- these types of prisoners are low level street dealers that end up back on
- the street. Even if lower level dealers are arrested and kept in jail, there
- are many more that will take their place. Finally, because there is an
- immense amount of competition on the streets, dealers are forced to keep
- their prices down to stay in business. Therefore, supply reduction used
- alone as a means for reducing society's drug problem appears ineffective.
-
-
- Treatment
-
- Similar to supply reduction, millions of dollars are spent every year on
- treatment as a means of curtailing drug use. And much like supply reduction
- strategies, treatment also shows little promise for eliminating drug use,
- particularly among adolescents.
-
- Much of the drug treatment literature suggests treatment for adolescents
- is ineffective (Hubbard, Cavanaugh, Graddock, & Rachal, 1983; Miller, 1973;
- Stein & Davis, 1982). Treatment effectiveness is most often measured by
- continued abstinence from drugs.
-
- Research on adolescent treatment programs suggests treatment, especially
- for adolescents, requires a lifestyle adjustment. This is to say that for
- most adolescents drug abuse is not a problem of physiological dependence.
- Rather, the problem stems from adolescent "life problems." Many researchers
- suggest that attention to these types of problems should be first and
- foremost (Bennett, 1983; Coupey & Schonberg, 1982). Researchers in the
- medical field agree adolescent drug abuse cannot be treated apart from
- family, school, and peer related problems (Macdonald & Newton, 1981;
- Mackenzie, 1982; Monopolis & Savage, 1982). This implies adolescent drug
- abusers are treated for the wrong problem since most programs are designed
- to deal with physical drug dependence. Research supports this argument by
- showing traditional drug treatment programs are ineffective in treating
- adolescent clients (Hubbard et al., 1983; Sells & Simpson, 1979).
-
- A review of treatment programs produces mixed results with no clear,
- conclusive evidence and studies plagued by methodological flaws. For
- example, Ogborne (1978) claims treatment is not effective, NIDA (1981)
- reports it is effective, and Einstein (1981) says a general evaluation
- cannot be made. However, Polich et al. (1984) and Beschner (1989) caution
- that few, if any, are backed by true scientific evaluations.
-
- Polich and his colleges (1984) reviewed several small scale treatment
- studies applicable to youthful drug abusers, none of which produced any
- large desired effects. A few studies did show some evidence of success.
- However, these results can most often be explained by rival hypotheses.
- Many studies found length of treatment stay to effect treatment success.
- Since many youth drop out of treatment programs it is not known whether
- these results are due to the increased benefit of treatment or to client
- self-selection. The lack of control group in the typical study also makes
- it difficult to evaluate the self-selection threat.
-
- Although adolescent treatment efforts in general have not demonstrated
- desired effects, this is not to say treatment should be abandoned.
- Instead, steps should be taken to restructure adolescent treatment
- programs to deal with general adolescent life problems. Perhaps then,
- treatment programs will show more promise as a strategy for reducing or
- eliminating adolescent drug use.
-
-
- Prevention
-
- Prevention holds more promise for controlling adolescent drug use
- than supply reduction or treatment. Reasons for promise include the
- timing of prevention programs and their focus on "gateway" substances -
- alcohol, tobacco, and marijuana. National data show youth initiating
- alcohol use as early as age 11 and marijuana and other illicit drugs at
- age 12 (Elliot & Huizinga, 1984). Because drug use often begins at such
- an early age, prevention programs must target youth before they come in
- contact with drugs. Currently, many drug prevention programs do in fact
- target youth while they are still in elementary school. This is especially
- important in light of the fact that the earlier an individual uses drugs
- the more likely they are to engage in greater and more persistent use of
- dangerous drugs (Flemming, Kellam, & Brown, 1982; Robins & Przybeck, 1985).
-
- Many studies indicate drug use begins with one of the "gateway"
- substances and follows a logical progression to experimentation with
- other drugs (Hamburg, Braemer, & Jahnke, 1975; Kandel, 1978; Loeber &
- Le Blanc, 1990; Richards, 1980). Prevention programs show promise because
- most, if not all, drug prevention programs focus on "gateway" drugs.
-
- Prevention efforts have not always been as promising, however. In the
- past, evaluations of many different prevention programs showed little or
- no effectiveness. Early studies were also methodologically weak. Since
- then there have been several "waves" of drug prevention programs each
- building on what was previously learned. More recent approaches have
- proven effective in reducing "gateway" drug use with studies demonstrating
- an increase in methodological rigor.
-
- Traditional prevention approaches include information dissemination,
- affective education, and alternative activities. These efforts are based
- on a misunderstanding about why adolescents engaged in drug use. For
- example, information dissemination programs assume adolescents use drugs
- simply because they lack information about such drugs. Information
- dissemination approaches provided adolescents with facts about the
- pharmacology of drugs, the uses of various drugs types, and the
- consequences of drug use. Fear arousal and moral persuasion are two
- variations of the information dissemination, or health education model
- that provide similar information, adding either scare tactics or moral
- appeals. Affective education focuses on clarifying values and increasing
- self-esteem assuming individuals lacking these attributes will use drugs.
- Similarly, alternative activities try to relieve boredom and provide
- adolescents with stimulating alternatives hoping they will engage in these
- activities instead of turning to drug use.
-
- Research clearly demonstrates the first generation of drug prevention
- programs has little or no impact on deterring adolescent drug use
- (Berberin, Gross, Lovejoy, & Paparella, 1976; Hanson, 1980; Kinder, Pape,
- & Walfish, 1980; Malvin, Moskowitz, Schaps, & Schaeffer, 1985; Schaps,
- Bartolo, Moskowitz, Palley, & Churgin, 1981). In fact, some programs are
- associated with an increase in drug use (Gordon & McAlister, 1982; Swisher
- & Hoffman, 1975).
-
- The second generation of drug prevention efforts has proven more
- effective in reducing adolescent drug use. Psychosocial approaches such
- as psychological inoculation, resistance skills training and, personal and
- social skills training target research-based risk factors for adolescent
- drug use. All of these programs focus on increasing an individual's
- personal and social competence through skill acquisition (Arkin, Roemhild,
- Johnson, Luepker, & Murray, 1981; Botvin & Dusenbury, 1987; Schinke &
- Gilchrist, 1985; Hansen, Johnson, Flay, Graham, & Sobel, 1988; Telch,
- Killen, McAlister, Perry, & Maccoby, 1982). Most programs teach personal
- and social skills such as problem-solving, decision-making, coping,
- resisting peer pressure, and assertiveness. Of the prevention efforts
- reviewed, the literature suggests continued psychosocial efforts be
- employed with emphasis placed on resistance skill training and personal
- and social skill training approaches. Follow-up, or booster sessions are
- recommended, however, since there is some evidence initial effects may
- decline (Botvin, Eng, & Williams, 1983).
-
-
- II. DARE (DRUG ABUSE RESISTANCE EDUCATION)
-
- DARE (Drug Abuse Resistance Education) is a drug abuse prevention
- program that focuses on teaching students skills for recognizing and
- resisting social pressures to use drugs. DARE lessons also focus on the
- development of self-esteem, coping, assertiveness, communications skills,
- risk assessment and decision making skills, and the identification of
- positive alternatives to drug use.
-
- Taught by a uniformed police officer, the program consists of 17 lessons
- offered once a week for 45 to 50 minutes. The DARE curriculum can only be
- taught by police officers who attend an intensive two-week, 80 hour,
- training. The DARE program calls for a wide range of teaching activities
- including question and answer sessions, group discussion, role play, and
- workbook exercises.
-
- The DARE curriculum was created by Dr. Ruth Rich, a curriculum
- specialist with the Los Angeles Unified School District, from a "second
- generation" curriculum known as Project SMART (Self-Management and
- Resistance Training) (Hansen, et al., 1988). DARE was piloted in fifty
- Los Angeles elementary schools with over 8,000 fifth and sixth grade
- students during the 1983-84 school year. Two years later, all 345
- elementary schools under the Los Angels Police Department's jurisdiction
- had a DARE officer assigned to teach the curriculum. The program, which
- originally targeted fifth and sixth grade students, was then expanded to
- include a junior high school curriculum and a much briefer orientation for
- students in kindergarten through fourth grade.
-
- DARE is one of, if not the most, wide spread drug prevention programs
- in the United States. In 1989, over three million children in 80,000
- classrooms were exposed to DARE ("Project DARE", 1990). Currently, there
- are DARE programs in every state in the United States and some counties
- have mandated DARE as part of the school health curriculum. It has also
- been implemented in several other countries including Canada, England,
- Australia, and New Zealand. In addition, it has been adopted by many
- reservation schools operated by the Bureau of Indian Affairs, and by the
- worldwide network of U.S. Defense Department schools for children of
- military personnel. There is a Spanish version and a Braille translation
- of the student workbook. Efforts are also under way to develop strategies
- for teaching DARE to hearing impaired and other special needs students.
-
-
- Previous DARE Evaluations
-
- Several DARE evaluations have been conducted over the last eight years
- in at least seven states and Canada (Agopian & Becker, 1990; Aniskiewicz
- & Wysong, 1987; Clayton, Cattarello, Day, & Walden, 1991; Clayton,
- Cattarello, & Walden, in press; DeJong, 1987; Earle, 1987; Evaluation and
- Training Institute, 1990; Faine, 1989; Faine & Bohlander, 1988, 1989;
- Manos, Kameoka, & Tanja, 1986; Nyre, 1985, 1986; Nyre & Rose, 1987;
- Ringwalt, Ennett, & Holt, 1991; Walker, 1990). Some show positive
- results, some show negative results, and most have serious methodological
- flaws.
-
- Most of the DARE studies conclude that DARE is a "success". However,
- success has various meanings. For some evaluations it means teachers and
- other school administrators surveyed said "DARE was a success". In other
- evaluations it means students responded they liked the DARE program. Still
- others claim success if teachers and students rate DARE as "useful" or
- "valuable". For the most part, success is based on the finding that
- students are more able to generate "appropriate" responses to a widely
- used 19 item questionnaire about drug facts and attitudes after the DARE
- program than before. In these last instances, almost all had no control
- group. Several of the studies above contain such severe methodology
- problems that any results, if cited, should be questioned. In a review of
- several of these studies, Clayton et al. (1991, p. 300) labels most of
- them as "at best pilot and/or descriptive in nature" and does not bother
- mentioning any of their findings.
-
- Methodological flaws contained in most of the DARE evaluations include
- one or more of the following problems: 1) no control group, 2) post-test
- only, 3) poorly operationalized measures, 4) low alpha levels for scales
- (<.50), 5) no statistical tests performed, and 6) pre-treatment differences
- not taken into account. Despite the lack of methodological rigor among
- most of these studies, three should be mentioned as they have corrected
- many (but not all) of the cited weaknesses. The results from these studies
- as well as any methodological flaws are reported below.
-
- For their experiment in North Carolina, Ringwalt and his colleges
- (1991) evaluated the DARE program using 1270 fifth and sixth grade
- students as subjects. They randomly assigned 10 schools to receive the
- DARE program and 10 schools to serve as controls.
-
- All students were pre-tested before the program began using a
- questionnaire designed to measure the following variables: self-report
- drug use, intentions to use drugs in the next year, attitudes towards
- drugs, perceived costs and benefits of drug use, perceived peer
- attitudes toward drug use, perceived media influences on drug use,
- self-esteem, and assertiveness. The reported internal reliability of
- all scales was favorable (.60 to .90)
-
- Significant pre-treatment differences were found on measures of race,
- sex, self-report alcohol use, general attitudes towards drugs, perceived
- peer attitudes towards drugs, costs of alcohol use, and perceived media
- influences.
-
- Controlling on pre-treatment differences, the dependent variable at
- time 1 (pre-test), and school type, it was concluded DARE met some of its
- immediate objectives. Significant differences between the experimental
- and control group include general attitudes towards drugs, attitudes
- toward specific drugs (beer, wine coolers, wine, cigarettes, and inhalants),
- perceptions of peers attitudes towards drug use, assertiveness, recognizing
- media influences to use drugs, and the costs associated with drug use.
- However, no statistically significant effects were found for self-reported
- drug use, future intentions to use drugs, perceived benefits of drug use
- (alcohol and cigarettes) or self-esteem.
-
- Ringwalt et al. (1991) conducted an evaluation study showing the DARE
- program had effects on some of the immediate outcome objectives. However,
- because the experimental and control groups were quite different to begin
- with, it could be argued that even though statistical controls were
- employed the groups probably differed on other variables not measured by
- the pre-test. These unmeasured pre-treatment differences could account
- for the observed post-test differences.
-
- A second point about the study should also be mentioned. The initial
- pages of the study explain the fact that methodological shortcomings have
- existed in drug program evaluations but that the current study improves
- upon one of those problems by performing statistical analyses appropriate
- for the research design. Continuing, in the results section the authors
- note prior evaluations have conducted the analysis at the wrong level.
- They make the argument that some studies have used individuals as the unit
- of analysis when schools have been assigned to treatment and control
- conditions. They immediately go on to say that in order to guard against
- any contamination of the results by school differences in their study,
- analysis of covariance, with school as a covariate, is employed. While
- the authors succeed at controlling for post-test differences associated
- with school membership, they still perform the analysis at a different
- level than the assignment, thus inflating the degrees of freedom.
-
- A second DARE evaluation also demonstrating methodological strength
- over previous studies is that of Faine and Bohlander (1988). The authors
- not only compared DARE to nonDARE students in the fifth grade but also
- looked at four school types in Frankfort, Kentucky - rural, parochial,
- inner-city, and suburban. Eight schools were randomly assigned to receive
- DARE and six were randomly assigned to the control condition in the Fall
- and Spring of the 1987-88 school year. Two additional control group
- schools were selected on the basis of school type to match the school
- characteristics of the experimental group. The randomization and
- selection process resulted in 451 experimental students and 332 control
- students.
-
- The six outcome variables measured were self-esteem, knowledge of
- drugs, attitudes towards drugs and alcohol, peer resistance, perceived
- external control and attitudes toward the police. There were no reported
- interaction effects between DARE and school type on any of the outcome
- measures. It should be noted that self-reported drug use was not examined.
- Comparing DARE to control students, they found significant differences in
- the expected direction for all six measures which included self-esteem
- (p<.05), attitudes towards the police (p<.001), knowledge of drugs (p<.001),
- attitudes towards drugs (p<.001), perceived external locus of control
- (p<.01), and peer resistance scores (p<.001). For some outcomes, such as
- self-esteem, the control group also improved from the pre- to the post-test.
- However, pre- to post-test analysis revealed the greatest gains for the
- DARE group.
-
- Faine and Bohlander (1989) extended their original evaluation by
- conducting two phases of a one-year follow up study. However, severe
- methodological problems prohibit drawing any conclusions. The first
- phase design involves testing the control and experimental cohort at the
- end of the 1988-89 school year in order to assess the long term
- effectiveness of DARE. However, after one year the control group had
- also received DARE. In this situation, any observable differences cannot
- confidently be attributed to the DARE program. This is especially true
- in light of the fact the authors reported the shift from the first to the
- second year meant the majority of students moved from an elementary
- school to a junior high school. The change in school structure alone
- could have influenced the results, not to mention other possibilities
- such as a maturation effect.
-
- Unfortunately, the second phase of the follow-up is just as
- methodologically flawed as the first. Because all students in the
- original DARE evaluation had received DARE by the end of the 1988-89
- school year, a control group from two additional counties was sought out
- in order to make comparisons. Since the additional control counties had
- not been pre-tested, there is no way of knowing if any pre-treatment
- differences existed between the control and experimental students before
- the experimental students were exposed to DARE. Although Faine and
- Bohlander's (1988) initial DARE evaluation produced convincing results,
- too many rival hypothesis exist to draw conclusions about the long term
- follow-up study.
-
- The last DARE study worth mentioning took place in Lexington, Kentucky
- (Clayton et al., 1991). During the 1987-1988 school year, the first of a
- five year longitudinal study, 23 schools were randomly assigned to the
- treatment (DARE) condition and 8 schools were randomly assigned as
- controls. The control group received the standard health curriculum which
- contained a drug education unit. The initial cohort was made up of 2,091
- sixth grade students.
-
- Initial equivalency tests indicate the treatment group had significantly
- more white students and significantly more positive attitudes towards drugs
- than the control group. The treatment group also reported significantly
- more lifetime, last year, and last month alcohol use.
-
- The authors used analysis of variance to compare the treatment and
- control group outcomes. However, they only controlled on race despite
- other pre-treatment differences. Statistically significant (p<.01)
- differences in the expected direction were found for general drug
- attitudes, and negative attitudes toward specific drugs (cigarettes,
- alcohol, and marijuana). Differences between the two groups were also
- found on the peer relationship scale (p<.05). Compared to the nonDARE
- group, the DARE students self-reported more popularity among their peers.
- Differences were not observed for self-esteem, peer pressure resistance,
- or self-reported drug use.
-
- A two-year follow-up study (Clayton, in press) examined the same
- cohort of 6th grade students using two follow-up questionnaires after
- the initial post-test. The first follow- up questionnaire was given
- during the 1988-1989 school year when the cohort was in the 7th grade
- and the second follow-up questionnaire was administered during the
- 1989-1990 school year when the cohort was in the 8th grade. Attrition
- rates over the two years did not differ significantly between the two
- groups.
-
- The long-term effects of DARE prove to be minimal in terms of past
- year alcohol, cigarette, and marijuana use. The only statistically
- significant difference occurred at the first follow-up for last year
- marijuana use. Unfortunately, this finding occurred in the opposite
- direction than that expected. Significantly more marijuana use was
- reported by the DARE students than nonDARE students. Otherwise, no
- significant effects were found at any other time for any other drug type.
-
- The long-term effectiveness of DARE was not demonstrated in the
- Lexington evaluation. However, Clayton and his colleagues (in press)
- suggest an alternative explanation for the lack of significant findings.
- They propose the lack of any long-term effects may be due to the fact
- that the control group was not in a no-treatment condition. Since it
- is not specified what the standard health curriculum (drug unit) entails,
- it is certainly possible the control students received similar education
- and training as that provided by the DARE program.
-
-
- Summary of DARE Evaluations
-
- Recent DARE evaluations demonstrate an improvement in methodology over
- earlier studies. The three DARE studies described above all use
- respectable research methodology. Summarizing the results of these
- studies is somewhat difficult given each one utilizes unique outcome
- measures such as recognizing media influences and costs and benefits of
- drug use (Ringwalt, et al., 1991) external locus of control and attitudes
- towards police (Faine & Bohlander, 1988) and peer relations (popularity
- among one's peers) (Clayton et al., 1991). However, all three studies do
- measure drug attitudes, self-esteem, and peer resistance (assertiveness)
- providing inconsistent results with respect to self-esteem and peer
- resistance (assertiveness). Findings from Ringwalt et al. (1991), Faine
- and Bohlander (1988) and Clayton et al.(1991) agree that DARE has an
- effect on drug attitudes. In all three cases, the treatment (DARE) group
- had significantly less positive attitudes towards drugs compared to the
- control group. There is a lack of agreement among all other outcome
- variables measured.
-
- Although other long-term studies have been attempted, the only one
- demonstrating adequate methodology is the Lexington study (Clayton et al.,
- in press). Possibly confounded by the lack of a true "no treatment"
- control group, the results do not warrant program success.
-
- In short, studies of the DARE program have produced mixed results and
- DARE evaluations up to this point are inconclusive. Further replications
- are necessary in order make more confident conclusions about the effects
- of the DARE program.
-
-
- DARE Compared to Most Promising Prevention Approach
-
- Several aspects of the DARE program make it a likely candidate for
- success. First, the program is offered to students just before the age
- when they are likely to experiment with drugs. Second, although there
- is little research on the effectiveness of law enforcement personnel as
- classroom instructors, uniformed police officers serve as teachers of the
- DARE curriculum in hopes of increasing favorable attitudes towards the
- law and law enforcement personnel. Third, the DARE program seeks to
- prevent the use of "gateway drugs" (i.e., alcohol, cigarettes, and
- marijuana), thereby decreasing the probability of subsequent heavier,
- more serious, drug use. Fourth, the DARE program draws upon several
- aspects of effective drug prevention efforts from the "second generation"
- such as the development and practice of life skills (coping, assertiveness,
- and decision making).
-
- Although DARE shows promise as a drug prevention strategy, more
- evaluation efforts need to take place before forming an overall
- conclusion about the program. This is especially important considering
- the fact that millions of government dollars are spent on this one
- particular drug prevention program every year and its dissemination
- continues to spread rapidly throughout the United States - all without
- any conclusive evidence concerning its effectiveness.
-
-
- III. OBJECTIVE OF THE PRESENT STUDY
-
- The purpose of the current study is to evaluate the effectiveness of
- the DARE program in Charleston County, South Carolina. Specific aims of
- the program include the stated DARE objectives - increasing self-esteem,
- assertiveness, coping skills, and decreasing positive attitudes towards
- drugs, actual drug use, and association with drug using peers. The
- study also examines the program's effectiveness for reducing other known
- risk factors associated with adolescent drug use such as social integration,
- commitment and attachment to school, and rebellious behavior.
-
-
- IV. METHODS
-
- Research Design
-
- The current study uses a nonequivalent control group quasi-experimental
- design (Campbell & Stanley, 1963) to determine if participating in the
- DARE program has any affect on the measured outcome variables compared to
- a similar group that did not receive the program.
-
- The DARE program took place during the Fall and Spring semesters of the
- 1989-90 school year. A student self-report questionnaire was used to
- measure the outcome variables. All pre- and post-tests were administered
- approximately 20 weeks apart.
-
- The survey administration was conducted by the school alcohol and drug
- contact person. The administration was conducted in such a way as to
- preserved the confidentiality of the students. All students were assigned
- identification numbers prior to the time of the pre-test. The
- identification number was used to link the pre- and post-test questionnaire
- responses. A questionnaire was distributed in an envelope with the
- student's name in the top right hand corner. Each name was printed on a
- removable label which the students tore off and threw away. The
- administrator read the cover page of the survey informing the students
- there was a number on the survey booklet which may be used to match their
- responses with questions asked later. The administrator also informed the
- students they had the right not to answer any or all of the questions.
-
- Response rates for the sample were high. Table 2 shows pre-test rates
- range from 79.3% to 98.5%, with an average response rate of 93.5% for the
- DARE students and 93.7% for the comparison students. An average of 90% of
- the DARE students and 86.4% of the comparison students completed the post-
- test. The pre- and post-test (combined) response rates were similar for
- both groups; 86.5% (295) of the treatment and 83.7% (307) of the
- comparison students completed both surveys.
-
- Statistical analysis procedures were performed to examine the
- differences between the DARE and nonDARE students. To begin, Analysis of
- Variance procedures were employed. This type of analysis enables pre-
- treatment differences on demographic or dependent measures to be detected
- and subsequently controlled for in later analysis. Controlling for any
- pre-treatment differences between the two groups and the measured dependent
- variable on the pre-test, the Analysis of Covariance procedure was used to
- detect significant differences at the time of the post-test.
-
-
- Sample
-
- Seven hundred eight fifth grade students from eleven elementary schools
- in Charleston County, South Carolina participated in the present study.
- Students came from five schools receiving the DARE program and six that
- did not. Of the 708 students involved in the study, 341 received the
- treatment (DARE), and 367 served as comparison students. The students
- came from schools representing a cross section of those found in the
- Charleston County School District. Three schools are urban, six suburban,
- and two rural.
-
- Each of the DARE schools was paired with a comparison school based on
- the following characteristics: Number of students, percent of students
- receiving free or reduced lunch, percent white, percent male, percent
- never retained, and percent meeting BSAP (Basic Skills Assessment Program)
- reading and math standards.
-
-
- Measures
-
- The You and Your School questionnaire was used to measure DARE
- objectives and other factors associated with later drug use. You and
- Your School was a preliminary version of What About You? (Gottfredson,
- 1990), a questionnaire designed to measure drug involvement and risk
- factors for later drug use.
-
- You and Your School consists of 10 scales and 4 sets of individual
- questions designed to measure the dependent variables. The ten scales
- used in the study are: 1) Belief in Prosocial Norms, 2) Social
- Integration, 3) Commitment to School, 4) Rebellious Behavior, 5) Peer
- Drug Modeling, 6) Attitudes Against Substance Use, 7) Attachment to
- School, 8) Self-Esteem, 9) Assertiveness, and 10) Positive Peer Modeling.
- Sets of individual variables include questions on attitudes about police,
- coping strategies, and drug use in the last year and last month. Appendix
- A shows the contents of each scale and the individual items used in the
- survey.
-
- Scale reliabilities were determined using Cronbach's alpha. Table 4
- shows the number of items in each scale and the corresponding reliability
- coefficients. Reliability coefficients range from .58 for Assertiveness
- to .85 for Social Integration. Each scale was calculated so that a high
- score indicates a high level of the factor. For all scales, the items
- were recoded so that the responses were in the same direction and averaged.
-
-
- V. RESULTS
-
- Pre-treatment Differences for DARE and NonDARE Students
-
- Comparisons were made between the DARE and nonDARE groups to assess
- initial equivalence on the demographic and outcome variables (see Table
- 5). Statistically significant pre-treatment differences were found for
- two of the three demographic measures. The DARE group had significantly
- more female students (p<.05) and more white students (p<.01) than the
- comparison group. The data indicate males made up 45% of the DARE
- group and 54% percent of the comparison group while white students made
- up 59% of the DARE group and 44% of the comparison group. No significant
- differences were found for the respondent's average age. The mean age
- for both groups of students was 10.3 years old.
-
- Three other measures were also shown to be significantly different for
- DARE and nonDARE students at the time of the pre-test. Before the DARE
- program began, a higher percentage of the DARE students reported smoking
- cigarettes in the last year. The DARE group was also found to be less
- attached to school and believe less in prosocial norms than the comparison
- group.
-
-
- Post-treatment Differences for DARE and NonDARE Students
-
- Initial analyses compared the DARE and comparison groups on each
- outcome measure without applying statistical controls for known pre-
- treatment differences (see Table 6). These analyses revealed differences
- between only two variables, peer drug modeling and attitudes against
- substance use, both at the p<.05 level. However, as shown in Table 7,
- controlling for pre-existing differences and the dependent variable
- measured prior to treatment, the DARE students initiated alcohol use less
- in the last year (p<.05), had higher levels of belief in prosocial norms
- (p<.01), reported less association with drug using peers (p<.01), felt
- more of their peer associations were positive or prosocial (p<.05), had
- an increase in attitudes against substance use (p<.001), and were more
- assertive (p<.05) than the comparison students.
-
- Other findings demonstrated no effect. DARE and nonDARE students did
- not differ significantly on the percent reporting cigarette, tobacco, or
- marijuana use in the last year or frequency of any drug use in the past
- month. Items targeting coping strategies and attitudes about police were
- also no different between the two groups. Finally, social integration,
- commitment and attachment to school, rebellious behavior, and self-esteem
- scale scores were not significantly different for those in the DARE program
- than for those not in the program.
-
- In summary, the evidence shows DARE students had more beliefs in
- prosocial norms, more attitudes against substance use, more assertiveness,
- and more positive peer associations than the comparison group. The DARE
- students also reported less association with drug using peers and less
- alcohol use in the last year. However, the DARE students were equivalent
- to the nonDARE students on social integration, commitment and attachment
- to school, rebellious behavior, coping strategies, attitudes about the
- police, self-esteem, and last year and last month drug use (with the
- exception of last year alcohol use).
-
-
- VI. DISCUSSION
-
- Limitations of the Present Study
-
- Several factors limit the present study. These are different units
- of analysis, selection threat due to lack of randomization, and multiple
- comparisons.
-
- The problem with the unit of analysis is that the treatment and
- comparison groups were determined by matching schools on specified school
- characteristics, the program was delivered to classrooms of students, and
- the analysis was performed at the individual level. The best solution to
- this problem would have been to randomly assign students to classrooms
- within schools where some classrooms would receive DARE and others
- classrooms would not. Assuming this could be done with many classrooms
- (at least 50), in several different schools, the analysis could be
- performed using the DARE and control classroom means. This was not
- possible since the evaluation was conducted after student assignment to
- classrooms and DARE assignment to schools had already taken place.
-
- Given the random assignment of children into classrooms was not
- possible, it then would have been better if schools were randomly
- assigned to receive the DARE program or serve as control schools. This
- would have decreased a selection threat since currently the argument could
- be made that the treatment and comparison schools were different to begin
- with on school characteristics other than those used for matching. As
- previously mentioned, the decision about which schools received DARE and
- which did not was determined prior to the beginning of the evaluation.
-
- The last issue worth mentioning is that of multiple comparisons. It
- is possible the significant outcome effects are overestimated due to the
- fact that the statistical tests performed were not independent but were
- treated as such.
-
-
- Current Findings and Comparisons
-
- The current DARE evaluation demonstrates the program's effectiveness
- on some of the measured outcome variables but not on others. The current
- study shows DARE does have an impact on several of the program objectives.
- Among these are attitudes against substance use, assertiveness, positive
- peer association, association with drug using peers, and alcohol use within
- the last year.
-
- It should be noted several of the variables showing no difference
- between the treatment and control groups are not specifically targeted
- by DARE (although they are shown to be correlated with adolescent drug
- use). Among these are social integration, attachment and commitment to
- school, and rebellious behavior. It could also be argued the DARE
- program does not specifically aim to change attitudes towards police
- officers, although this may be a tacit objective. Since the program does
- not target these outcomes specifically, it may not be surprising there
- were no differences found between the DARE and nonDARE groups. It was
- hypothesized the DARE program may impact factors relating to later
- adolescent drug use even if those factors were not specific aims of the
- program but this hypothesis did not hold true. In a sense this is
- evidence that helps to reject the selection argument. If the positive
- results were due to selection, they would not be found only for the
- outcomes targeted by DARE.
-
- Much like the three previously reviewed DARE evaluations, the current
- study adds to the mixed results produced thus far with one exception.
- Across all studies using a pre-post comparison group design, DARE students'
- attitudes against drug use have consistently been shown to increase and
- differ significantly from the control students. Since favorable attitudes
- towards drug use has been shown to predict or correlate with later
- adolescent drug use (Kandel, Kessler, & Margulies, 1978) this finding
- provides some of the most convincing evidence that DARE shows promise as
- a drug prevention strategy.
-
- On the other hand, there are no other consistent findings for
- assertiveness (resisting peer pressure), self-esteem, or attitudes
- towards police. The current study found an increase in assertiveness
- among the DARE students as compared to the nonDARE students. Ringwalt et
- al. (1991) and Faine and Bohlander (1988) also found this to be true but
- Clayton et al. (1991) did not. Effects on self-esteem were not
- demonstrated in the present DARE evaluation nor were they in Clayton's
- (Clayton et al., 1991) or Ringwalt's (Ringwalt et al., 1991). However,
- significant differences in self-esteem were seen for the DARE participants
- over the controls in Faine and Bohlander's (1988) study. Thus, the
- Charleston study helps to increase the consistency of the assertiveness
- and self-esteem results.
-
- Faine and Bohlander's (1988) study also showed positive attitudes
- towards police were significantly greater for the treatment group than
- the control group but the present study did not replicate such findings.
- However, the difference found between these two studies may be due to the
- measures used. The current DARE study uses only two single item questions
- to assess students' attitudes about the police whereas Faine and Bohlander
- (1988) used an 11-item scale. Moderate to high factor loadings (.27 to
- .82) were reported for each item in the scale, and although the overall
- reliability was not reported, Faine and Bohlander's (1988) measure of
- police attitudes is likely to be more valid.
-
- With reference to drug use, all of the stronger DARE evaluations
- found no effects with the exception of the current study which found a
- significant difference on last year alcohol use. Clayton's follow-up
- evaluation showed only one significant difference in the wrong direction
- on the first of two follow-up post-tests (Clayton et al., in press). As
- Clayton et al. (in press) points out, the lack of short-term drug use
- differences may be due to low base rates and thus, should not be
- interpreted to mean DARE has no effect on adolescent drug involvement.
-
- Recommendations
-
- Replication studies of the evaluation of the DARE program should
- be continued since mixed evidence exists about the program's overall
- effectiveness. Conducting randomized experiments would certainly be best
- for drawing more confident conclusions about DARE program outcomes.
- Longitudinal studies would also aid in assessing the long-term program
- goal of deterring adolescent drug use.
-
- There is one large problem with recommending a long-term study on a
- drug prevention program that is conducted in schools in the United States.
- The problem involves finding a true "no treatment" control group. Almost
- every school in the nation has some type of drug education component
- embodied in the school curriculum which is often mandated by the state.
- Therefore, it is likely the control group will receive some form of
- drug education. This problem has been documented as Clayton's (Clayton
- et al., in press) study used a comparison group that received the school
- drug education unit and ETI (Evaluation and Training Institute) had to
- discontinue their 5-year longitudinal study because the entire control
- group had essentially become a treatment group (Criminal Justice
- Statistics Association, 1990).
-
- In the future, it may be possible only to compare student's receiving
- some specified drug prevention program with the school system's drug
- education unit. However, this appears acceptable if the school system
- simply requires a unit session on factual drug information or a similar
- low level intervention since prevention efforts such as this have
- consistently been shown to have no positive effects (Berberin et al.,
- 1976; Kinder et al., 1980; Schaps, et al., 1981; Tobler, 1986).
-
- Should evaluations of the DARE program continue, it is suggested one
- national survey instrument be developed and used for all outcome
- evaluations. Currently, it is difficult to assess whether or not DARE
- is actually a success since different researchers use different survey
- instruments to examine a variety of outcome measures. Measuring DARE
- program objectives and other risk factors associated with later drug use
- with one survey would enable researchers to compare results across
- evaluations conducted in U.S. cities and other parts of the world.
-
- Additional recommendations include employing peer leaders (i.e., high
- school students) as instructors instead of police officers. There are
- two reasons for this suggestion. First, it has not been consistently
- demonstrated that attitudes towards police become more positive upon
- receiving the DARE program, and second, there has been some evidence
- supporting the use of peer leaders as primary program providers (Arkin,
- et al., 1981; Botvin & Eng, 1982; Botvin, Baker, Renick, Filazzola, &
- Botvin, 1984; Perry, Killen, Slinkard, & McAlister, 1980).
-
- It would be not only interesting, but informative, to compare DARE
- program outcomes utilizing peer leaders vs. police officers as instructors.
- Should peer leaders provide equal or better outcomes, DARE programming
- costs would be considerably less and police officers would be more
- readily available to respond to citizen calls.
-
- It is further recommended that DARE be restructured to incorporate
- components shown more consistently to be effective such as those found
- in "second generation" approaches. Although DARE aims to increase
- resistance skills, coping, and decision-making, the lessons specifically
- targeting these factors do so in the context of drug use only. As
- previously mentioned adolescents engaging in drug use behavior are often
- involved in other problem behaviors (Jessor & Jessor, 1977). It would
- seem most practical and beneficial to target all of these behaviors
- utilizing one program as Botvin (1982) and Swisher (1979) have suggested.
- The DARE program could serve as this one program assuming several changes
- were implemented.
-
- First, existing components would have to be expanded and additional
- components added in order to target more broad based adolescent life
- problems such as family struggles, peer acceptance, sexual involvement,
- intimate relationships, and effective communication (expressing ideas,
- listening). Additional sessions should include components from "second
- generation" programs such as setting goals, solving problems, and
- anticipating obstacles (Botvin, et al., 1983; Schinke & Gilchrist, 1985).
-
- Second, skill acquisition is said to come about only through practice
- and reinforcement (Bandura, 1977). It is proposed that any new skills
- taught, such as problem solving, be reinforced with "real life" homework
- where students practice these skills in the context of the "real world"
- rather than simply role playing them in the classroom.
-
- The last recommendation is applicable not only to the DARE program but
- any drug prevention effort. It involves the addition of booster sessions
- following the prevention program. Since adolescence is a time of growth,
- individual attitudes and behaviors may continue to change and develop as
- the youth is maturing. While short-term evidence of program effectiveness
- is encouraging, there is no guarantee a youth will continue to practice
- those same behaviors or hold those same beliefs years, or even months,
- after the program has ended. In fact, follow-up studies have documented
- the eroding effects of drug prevention programs (Botvin & Eng, 1980;
- Botvin & Eng, 1982) and the superior effects of booster session (Botvin et
- al., 1983; Botvin, et al., 1984). For these reasons, DARE, or any other
- drug prevention program targeting adolescents, should include a series of
- follow-up sessions in order to increase the likelihood of sustaining any
- positive effects.
