An elementary school-based alcohol misuse prevention program: a follow-up evaluation.

An alcohol misuse prevention study (AMPS) curriculum for fifth- and sixth-grade students was developed, implemented and evaluated with over 5,000 students. The AMPS program emphasized social pressures resistance training, focusing on the immediate effects of alcohol, risks of alcohol misuse and social pressures to misuse alcohol. Schools were randomly assigned to curriculum, curriculum plus booster or control groups with half of each group pretested and all posttested. Measures focused on susceptibility to peer pressure, internal health locus of control, understanding of the curriculum material, alcohol use and alcohol misuse. After 26 months, there was a significant treatment by occasion interaction on internal health locus of control (sixth grade). A significant treatment by occasion interaction effect was also found with respect to curriculum measures in both grades. There was no significant treatment by occasion interactions with respect to alcohol use or misuse when the groups as a whole were considered. When subgroup analyses based on type of prior drinking experience were conducted, however, significant program effects on alcohol misuse were found among sixth-grade students who had experienced unsupervised as well as supervised drinking prior to the prevention program.

Ethnographic methods in the development of census procedures for enumerating the homeless.

The use of ethnographic methods to estimate the number of homeless persons in the United States is explored. The authors describe how "ethnographic methods were integrated with survey procedures in a 1989 Census Bureau pilot test of an experimental daytime count of homeless persons in Baltimore, MD. We demonstrated that ethnographic techniques do not have to be merely supplemental to survey research, but can play an integral part in shaping the entire procedure. Ethnographic data proved valuable for choosing sites, designing questionnaires and developing new interview approaches, and have since proven equally useful in interpreting the test results."

Pretest and treatment effects in an elementary school-based alcohol misuse prevention program.

Forty-nine schools (N = 5,680 fifth and sixth grade students) were assigned to pretest/treatment, pretest/no treatment, no pretest/treatment, and no pretest/no treatment conditions in the context of an alcohol misuse prevention study. At the first posttest, five months after the pretest and two months after the intervention, the effects of the pretest and of the intervention were examined. The analyses showed that failure to correct for the design effect due to clustering within schools resulted in the overestimation of the significance of treatment and pretest effects. After correction for the design effect, a significant treatment effect in the hypothesized direction was found with respect to students' awareness of the content of the curriculum. As hypothesized, significant treatment effects on the alcohol use and misuse measures had not yet developed but are expected to occur at subsequent posttest occasions. Significant pretest effects were found for indices measuring trouble with peers resulting from students' alcohol use, students' internal health locus of control, and their perceptions of adults as a locus of control for their health. Two of the three pretest effects were in the direction that would be hypothesized if the pretest were providing the same impetus as the intervention. Implications of these findings for school-based substance abuse prevention programs are discussed.

A covariance structure model test of antecedents of adolescent alcohol misuse and a prevention effort.

As part of an alcohol misuse prevention evaluation, questionnaires were administered to 4,157 junior high school students to determine levels of alcohol misuse, exposure to peer use and misuse of alcohol, susceptibility to peer pressure, internal health locus of control, and self-esteem. A conceptual model of the antecedents of adolescent alcohol misuse and the effectiveness of a prevention effort was tested using covariance structure modeling techniques. The factor loadings for the model were all moderate to high, indicating that the observed variables served well as measurement instruments for the latent variables. The hypothesized structural relationships among the latent variables of alcohol misuse, exposure to peer use and misuse of alcohol, susceptibility to peer pressure, internal health locus of control, and self-esteem were supported by the data. The full model explained 45 percent of the variance in alcohol misuse in the analysis based on the total sample. The direct effect of the intervention on alcohol misuse was small but significant in the hypothesized direction. The direct effects of the intervention on susceptibility to peer pressure and internal health locus of control were not significant. The model was tested separately for groups of students who had high versus low scores on susceptibility to peer pressure in order to test the interaction between susceptibility to peer pressure and exposure to peer use and misuse of alcohol. The percentage of variance accounted for in alcohol misuse did not increase upon testing the model separately for students who had high versus low scores on susceptibility to peer pressure. Observed differences in the significance of the parameter estimates between the high and low susceptibility to peer pressure groups suggest that different approaches to the design and evaluation of substance abuse prevention programs may be necessary for different subgroups of students.

Susceptibility to peer pressure, self-esteem, and health locus of control as correlates of adolescent substance abuse.

As part of a school-based alcohol misuse prevention study, questionnaires were administered to 2,589 fifth and sixth grade students to determine levels of use of alcohol, marijuana, and cigarettes, intentions to use these substances, and problems resulting from alcohol misuse. The questionnaire also included 45 items concerning susceptibility to peer pressure, self-esteem, and health locus of control. These 45 items were factor analyzed separately for two groups formed by random assignment. Six factors were identified which were both internally consistent and replicable, and indices were constructed. The indices measuring susceptibility to peer pressure, self-esteem, and internal health locus of control were significantly and negatively correlated with most of the substance use, misuse, and intention items, and an external health locus of control index was not significantly related to most of the substance use, misuse, and intention items. The "Susceptibility to Peer Pressure" index correlated more highly with the adolescent substance use, misuse, and intention items than the self-esteem or the health locus of control indices, and it had the highest alpha coefficient. Implications for the design of school-based substance abuse prevention programs are discussed.

Validity of adolescents' self-reports of alcohol use and misuse using a bogus pipeline procedure.

Past research, particularly in the area of adolescent smoking behavior, has suggested that more valid self-reports of socially undesirable behavior can be obtained when a bogus pipeline procedure is implemented. "Bogus pipeline" refers to a methodology in which subjects are informed that their self-reports can and will be objectively verified by the researcher through a procedure such as a biochemical test. In actuality, no verification takes place. Recent studies using this methodology have produced mixed results. In the current study, a bogus pipeline procedure designed to increase the validity of adolescents' self-reports of alcohol use and misuse was devised and evaluated as part of the pilot work for an alcohol misuse prevention study in southeastern Michigan schools. A total of 291 students in grades seven through nine were tested in the pilot study. Of these, 173 experienced the bogus pipeline approach in which saliva samples were collected, while 118 served as controls. The differences between the two conditions were examined with respect to nine variables concerning alcohol use and misuse. An overall frequency of use index and an overall misuse index were also examined. Two-way analyses of variance (treatment by grade level and treatment by gender) were conducted. The F values for a main effect of treatment ranged from .00 to 1.27 for the 11 variables. None of these was significant at the prespecified alpha level of .20. In addition, there was no interaction of the treatment procedure with either grade level or gender. In the context of a school-based study in which confidentiality was assured, adolescents' self-reports of alcohol use and misuse were not significantly affected by a bogus pipeline procedure.

Elementary school-based prevention of adolescent alcohol misuse.

The literature on the prevention of alcohol misuse and other substance abuse shows that most prevention program efforts to date have not been successful. Some possible reasons for this lack of success are discussed, and a recent, promising approach to the problem is outlined. An example of that approach, the Alcohol Misuse Prevention Study (AMPS), is described and early findings are presented. Conceptual and methodological issues considered in the design, implementation and evaluation of AMPS are discussed as examples of the planning which must go into a well-designed alcohol misuse prevention program. Issues now being raised in the evaluation of AMPS are presented with their implications for future prevention programs.

The community residential treatment service: developing a continuum of prosthetic environments for the chronically disabled.

Among the many issues regarding the care of chronic mental patients, none is more pressing than the need for administrative and clinical models designed to organize and systematize the efforts of diverse community service providers. This paper describes the functioning of the Community Residential Treatment Service of the South Beach Psychiatric Center, a large-scale project of a state facility created to respond to this tissue. By blending sophisticated clinical and administrative technology, programs operated by the state, voluntary, and proprietary health care sectors have been integrated to form a balanced service delivery system. This system provides a broad continuum of inpatient and outpatient residential settings developed in accordance with social learning principles. The components of the system, with the Community Residential Treatment Service as the major integrative force, are linked together by detailed contracts as well as common behavioral clinical and behavioral administrative language. The treatment successes f this system have been significant enough to suggest that a positive synergistic effect is generated by this programming combination.

Demographic correlates of SI assessments of type A behavior.

A survey interview and the structured Type A interview (SI) were administered to 903 residents of Washtenaw County, Michigan aged 18 or older selected by a multistage probability sample of households. No bivariate relationship was found between Type A behavior and sex or marital status. Type A behavior was positively related to income and education. The prevalence of Type A behavior was highest among those who were employed in white-collar occupations. There was an inverted U-shaped relationship between age and Type A behavior. A slightly higher prevalence of Type A behavior was noted among whites than among nonwhites. Multivariate analysis showed the seven demographic variables to account for 6.8% of the overall variation in Type A behavior, with family income being the strongest demographic predictor.
