Use of the "theme study" as means of curriculum development in continuation high schools.

This article presents the evaluation of written paragraphs which described twenty-one drug abuse prevention "themes" contained in thirty-five separate activities, as part of the process of curriculum development targeting Continuation High School students. The goal was to determine which activities were most preferred by these youth. The paragraphs consisted of descriptions of traditional drug abuse prevention program activities, alternative activities using the themes underlying traditional activities, and novel activities generated from newly developed themes. The study was conducted with seven Continuation High Schools. Three hundred and fifteen students participated in this study. Each student rated detailed written descriptions of five activities. Classrooms were randomly assigned to different combinations of paragraphs. An analysis of variance indicated that there were significant differences in preferences among activities, with a marked preference for the alternative and novel activity presentations. Females, Latinos, older students, and non-marijuana users rated the activities higher overall. There were no significant interactions between demographic variables and order of activity preference. If there is a limit in amount of allotted time and resources, the theme study is an appropriate and cost-effective tool for gaining important information for health curricula development.

Two-year behavior outcomes of project towards no tobacco use.

The article presents 2-year follow-up data from a school-based tobacco use prevention project designed to test the effectiveness of 3 primary components in social influence programs. The components either teach refusal skills, awareness of social value misperceptions, or physical consequences. Curricula were tested with a randomized experiment involving 48 junior high schools. These data suggested that (a) a physical-consequences curriculum is successful at attenuating increases in adolescent smokeless tobacco use, (b) cigarette experimentation may be attenuated by various approaches, and (c) a comprehensive program with all 3 components was necessary to attenuate increases in weekly use of both forms of tobacco. These results also indicate that school-based tobacco use interventions can be effective at least 2 years postprogram, after students make their transition to high school.

Psychosocial predictors of health risk factors in adolescents.

Previous research has confirmed the role of problem-behavior theory constructs as predictors of nonconventional behaviors such as adolescent drug abuse. No prospective study, however, has examined this theory's relevance to less extreme nonconventional adolescent behaviors, such as poor health practices. In the present study, an attempt was made to predict an index composed of seven health risk factor items measured in 8th grade from numerous variables measured in 7th grade selected to reflect personality, perceived environment, and behavior systems of problem-behavior theory. In addition, problem-behavior theory was compared in predictive efficacy to a wellness notion. Factor analysis did not support the construct validity of the three systems as measured herein. Instead, resulting empirically derived factors reflected domains labeled "wellness," "subjective distress," and "problem behavior." In addition, linear regression results indicated that constituents of wellness, subjective distress, and problem-behavior domains, as well as the demographic variable of lower socioeconomic status, and taking less care of one's own physical health in 7th grade, were predictors of taking less care of one's physical health the next year. One interpretation of these results is that lack of a sense of wellness may lead one to yield to problem behavior-related social environment influences including participation in poor health practices.

Continuation high schools: youth at risk for drug abuse.

Students at alternative high schools may be at substantial risk for drug abuse. The present article provides a general overview of the drug use-related context of continuation high schools in southern California. A total of 144 students and ninety-six staff were interviewed from twenty continuation high schools. The interview data revealed that continuation school students show high levels of substance use. However, only 20 percent of the students report that they received any drug abuse prevention programming. Also, students at continuation high schools aspired to a productive life after high school including continued education. Thus, these youth may still be amenable to preventive educational interventions which deter them from drug use and help them to fulfill their future goals.

Group self-identification and adolescent cigarette smoking: a 1-year prospective study.

As an extension of previous work, we analyzed the longitudinal relations between group self-identification and adolescent cigarette smoking. The predictive precedence of cigarette smoking and identification with 6 different types of peer groups was examined. Results indicated that 7th-grade group self-identification predicted 8th-grade cigarette smoking, whereas 7th-grade cigarette smoking did not predict 8th-grade group self-identification. Group self-identification also was compared with 7 other psychosocial variables as predictors of smoking 1 year later. The pattern of results suggests that group self-identification is about as good a predictor of smoking as other psychosocial variables, and that group self-identification is more than a mere proxy of other psychosocial variables.

Attitudes and health behavior in diverse populations: drunk driving. Alcohol use, binge eating, marijuana use, and cigarette use.

Five different health behaviors (cigarette use, alcohol use, binge eating, illicit drug use, and drunk driving) were studied prospectively in 5 different groups of subjects. Associations between attitudes toward these behaviors and the behaviors themselves were investigated over at least 2 waves of measurement. Findings revealed that attitudes predicted behavior nonspuriously in 2 instances: alcohol use and marijuana use. Attitudes did not predict drunk driving, binge eating, or smoking behaviors. Past behavior predicted attitude in the domains of binge eating and smoking, but not in the domains of alcohol use, drunk driving, or marijuana use. The results are discussed in terms of several alternative approaches that have implications for interventions that attempt to influence health behavior through attitude change.

Refusal assertion versus conversational skill role-play competence: relevance to prevention of tobacco use.

Conversational and refusal assertion skills of 768 seventh grade youth were assessed through ratings of global (for example, effectiveness) and non-verbal (for example, eye contact) behaviour performed in two role-play scenarios. The ratings were completed after each scenario by the subjects themselves, as well as by classmate and trained adult observers. Use of the Hays and Hayashi multitrait scaling method to interpret these data revealed two results. First, the items used to measure role-play behaviour did not achieve sufficient internal consistency to create global and non-verbal composites. Second, inter-rater agreement and discriminant validity were obtained only for ratings of the global effectiveness of each of the two social skills. Next, a series of multiple regression analyses indicated that an index of the global effectiveness of refusal assertion skill, but not of conversational skill, was predictive of intention to use tobacco. Those who were relatively unskillful at refusing offers were more likely to intend to use tobacco. Analyses exploring relations of trained observer ratings of the effectiveness of both role-play types, trained observer ratings of the other global and non-verbal items, and subjects' intention to use tobacco indicated that only a hesitant voice pattern was both negatively predictive of effective refusal assertion and positively predictive of intention to use tobacco in the future. In other words, those who are hesitant when they refuse a tobacco offer are the ones most likely to report an intention to use tobacco in the future. The consistency of this last finding in the tobacco use prevention literature is discussed.

Generality and specificity in health behavior: application to warning-label and social influence expectancies.

The authors outlined a meta-theoretical and an analytic framework for construing the predictive effects of health-behavior expectancies, or beliefs, in terms of both general and specific processes. This framework was applied empirically to the investigation of the predictive effects of outcome expectancies related to the recently mandated alcohol-warning label as well as to expectancies reflecting social influence processes. Results showed that general and specific predictive effects of expectancies on alcohol-use behaviors operated simultaneously, demonstrating the potential value of the framework. The authors summarized implications for continued theoretical development as well as for applications in prevention of alcohol abuse through warning-label and social influence interventions.

Project Towards No Tobacco Use: implementation, process and post-test knowledge evaluation.

This paper describes the curricula contents, and presents data to evaluate the implementation, process and immediate post-test knowledge of Project Towards No Tobacco Use (Project TNT). Four different school-based tobacco use prevention curricula were developed to counteract the effects of three types of tobacco use acquisition variables typically addressed within a comprehensive social influences program: (1) peer approval for using tobacco (normative social influence), (2) incorrect social informational provided about tobacco use (information social influence) and (3) lack of knowledge or misperceptions about physical consequences resulting from tobacco use. Three curricula were designed to counteract the effects of single acquisition variables, whereas a fourth curriculum was designed to counteract the effects of combined social and physical consequences-related influences. These curricula were delivered to seventh grade students by trained project health educators to maximize implementation. 'Program' schools, those schools that received one of these curricula, were compared to 'control' schools that provided asystematic health education delivered by school personnel. A total of five conditions were contrasted through use of a randomized experiment involving 48 southern California junior high schools. This paper documents high levels of implementation in all program conditions. Also, favorable process ratings were obtained across the four program conditions, using multiple measures and sources of ratings (students, health educators and classroom teachers who observed curricula delivery). Finally, knowledge item sets completed by the students demonstrated discriminant validity across all five conditions. Because the program conditions were discriminable, yet were quite similar in implementation and process ratings, planned future study of behavioral outcomes can be interpreted as relatively uncontaminated by delivery or credibility confounds.

The alcohol warning label and adolescents: the first year.

Awareness of the alcohol labeling law and exposure to, beliefs about, and memory for the government-mandated alcohol warning label were measured in a sample of adolescents immediately before the label was required to appear (in the fall of 1989) and 1 year after the label was required. After the label was required, there were increases in awareness, exposure, and recognition memory, but there were not substantial changes in alcohol use or beliefs about the risks written on the warning.

Project towards no tobacco use: 1-year behavior outcomes.

OBJECTIVES: We present 1-year follow-up data from a school-based tobacco use prevention project designed to test the effectiveness of three main components of social influence programs. The components teach refusal skills, awareness of social misperceptions about tobacco use, and misconceptions about physical consequences. METHODS: Four different curricula were developed and tested in a randomized experiment involving 48 junior high schools. The outcome variables examined were changes in initial and weekly cigarette and smokeless tobacco use 1 year after the intervention. RESULTS: Analyses indicated that each of the component programs were effective in decreasing both the initial and the weekly use of cigarettes except for the curriculum in which refusal skills were taught. Also, each curriculum was effective in decreasing the initial use of smokeless tobacco except for the one aimed at correcting social misperceptions. Only the combined curriculum showed an effect on the weekly use of smokeless tobacco. CONCLUSIONS: The combined intervention was the most effective overall in reducing the initial and weekly use of cigarettes and smokeless tobacco. This suggests that different reasons for use exist and need to be counteracted simultaneously. However, since single programs were also effective in reducing all but weekly smokeless tobacco use, any of these components may be worthwhile prevention tools.

Naturalistic observation of adolescent tobacco use.

A naturalistic observation study of adolescent tobacco use was conducted to corroborate previous studies which used self-report questionnaire or structured interview methods to study this problem behavior. Several findings converged with previous accounts of adolescent tobacco use. For example, most use occurred in small groups. However, other findings diverged somewhat from previous research in that an unexpectedly low number of offers of tobacco was observed, nonusers were present in smoking groups, and solitary smoking was common. These data suggest that direct, normative social pressure to use tobacco may not be as frequent as more subtle informational social influence, at least in high school adolescent tobacco use groups.

Construct validity of dimensions of adaptive behavior: a multitrait-multimethod evaluation.

The construct validity of four dimensions of adaptive and maladaptive behavior was investigated using the multitrait-multimethod matrix procedure of Campbell and Fiske (1959). Measures of four traits--cognitive competence, social competence, social maladaption, and personal maladaption--were obtained on a sample of 157 persons with moderate, severe, or profound mental retardation using each of three methods of measurement--standardized assessment instrument, day shift staff ratings, and evening shift staff ratings. Applying the Campbell and Fiske rules of thumb and recently proposed structural equation modeling techniques to the data demonstrated strong convergent validity, clear discriminant validity, and only moderate levels of method variance in the observed measures. Implications of the results for the assessment of adaptive behavior and its dimensional structure were discussed.

Interactive and higher-order effects of social influences on drug use.

The study of moderators and higher-order effects of social influences on drug use has many implications for theories of health behavior. In the present study, we investigated the longitudinal predictive effects of some of the prominent moderator variables that represent forms of susceptibility toward social influence in teenage drug use. We also studied the possibility that social influence may predict drug use in nonlinear (quadratic) forms, consistent with theories proposing that threshold or decelerating effects may occur in social influences on normatively sanctioned behaviors. Results showed that several of the interactive and quadratic predictive effects were significant. The findings supported the views that certain moderator variables act as buffers, which either protect the individual from social pressures to use drugs, or make the individual more susceptible to such pressures. In addition, two of the obtained quadratic effects of social influence lent support to the application of social impact theory to drug use. Overall, our findings suggest that interactive and nonlinear approaches to social influences on drug use provide a unique and viable theoretical perspective from which to construe this problem health behavior.

Cognitive motivation and drug use: a 9-year longitudinal study.

The predictive precedence of expectancy constructs, operationally defined as cognitive motivations, and drug use was investigated over a 9-year period from adolescence to adulthood. Alternative predictions from three different classes of theories of expectancy-behavior relations, including expectancy theory, a Skinnerian approach, and a reciprocal determinism perspective, were evaluated. The results are most consistent with the notion based in expectancy theory that cognitive motivations are nonspurious and possibly functionally autonomous influences on the use and abuse of drugs. More limited support is found for the view that drug use leads to cognitive motivations, as postulated in other theoretical perspectives. Other findings reveal the presence of expectancy generalization processes consistent with Rotter's (1954) expectancy theory, as well as the unique status of cognitive motivations for alcohol as an independent predictor of problem drug use.

Personality, problem drinking, and drunk driving: mediating, moderating, and direct-effect models.

Three different general explanations of the effect of personality on problems from drinking alcohol were investigated. One general explanation involved mediating effects. The 2nd explanation involved direct effects of personality. The 3rd general personality process held that alcohol consumption and personality interact as moderating effects on drinking problems. Results provided support for each of the 3 general explanations of personality effects, although certain effects were found primarily for only 2 of the 6 personality constructs investigated (sensation seeking and cognitive motivation). These findings helped delimit the personality processes associated with drinking problems and demonstrated the viability of several specific processes that go beyond traditional assumptions about personality and problem drinking.

On the scope of alcohol expectancy research: remaining issues of measurement and meaning.

An article by Leigh (1989d) examined certain substantive and measurement-related limitations of research on alcohol outcome expectancies. Leigh (1989d) criticized research in this field on both conceptual and methodological grounds and speculated on future theoretical directions for research in the field. In their response, Goldman, Brown, Christiansen, and Smith (1991) contended that Leigh's critique is faulty in important respects. However, some of their points are based on misinterpretations of Leigh's comments, and they appear to have insufficient appreciation of conditions necessary for comprehensive measurement validation and for meaningful application of theories of memory to alcohol expectancy research. Despite the limitations of expectancy research, exciting avenues exist for further work.
