Lifetime experiences with vaginal and oral sex were most common (19% and 16%, respectively); fewer reported anal sex (6%). Of the 23% reporting any sex, 91% fell into four categories: 36% reporting both oral and vaginal sex; 23% vaginal only; 18% all three; and 13% oral only. Most sexually experienced students (88%) initiated with vaginal or oral sex (46% vaginal, 33% oral, 9% both same day). No dominant pathway of sexual onset emerged for those reporting all three types of sex. We found no evidence that oral or anal sex substituted for or delayed vaginal sex. Males, those with a current partner, and those reporting multiple partners were more likely than others to repor...

Most women (73-85%) reported participating in decisions about condom use, contraception, and when to have sex. Adjusting for potential covariates, respondents who reported participating in decisions about condom use and when to have sex were 7 and 19 times, respectively, more likely than others to report recently using condoms. Respondents who reported participating in decisions about contraception were 20 times more likely than others to report recently using contraceptives. Longer sexual relationships were associated with decreased likelihood of condom or contraceptive use.

A total of 24 schools participated in three randomized conditions: TND Only, TND and motivational interviewing follow-up, and no treatment control. Fidelity was high: across program schools the curriculum was implemented as intended and was received favorably by students. Relative to controls, intervention conditions produced effects on hypothesized mediators, including greater gains in program related knowledge, greater reductions in drug use intentions, and positive changes in motivation. However, few generalizations to attitudes and intentions regarding risky sexual behavior were found. The pattern of results suggests that the experimental manipulations worked as intended.

Where relevant, continuity of translation is discussed by referring to two variables that have been studied for their potential relationship to drug use risk in both animals and humans: sensation and novelty seeking and low impulse control. Review of the research indicates relatively slow translation until the early 1990s. The authors recommend several mechanisms to promote more rapid translation across types of research that encourage reciprocal rather than unidirectional transmission of knowledge to expedite the development and diffusion of more timely, targeted drug abuse prevention programs.

We found increased FTP to be protective against drug use for all substances except alcohol. While any baseline use of substances did not predict changes in FTP 1 year later. The discussion explores why alcohol findings may differ from other substances. Future consideration of FTP as a mediator of program effects is explored.

However, there has been little empirical evaluation of community coalitions. The present paper presents case studies of two different coalition models, one a coalition developed to support a community-based drug abuse prevention trial, and the other, a CSAP Community Partnership Demonstration Program site. Comparison of the two coalitions on key characteristics indicated that they were similar except for their impetus for initiation (researcher-versus community-initiated) and primary purpose (to support experimental program components versus to coordinate prevention programming and develop new prevention services). Members of the two coalitions (n = 51 in the researcher-initiated, and n = 49 in the communityinitiated coalition) responded to a written survey that assessed immediate coalition process and activity outcomes, including perceptions of coalition efficiency, outcome efficacy, interagency coordination, and benefits of involvement. After controlling for demographic differences, the two groups of coalition members were similar, overall, on the measures of immediate outcomes. Univariate analyses indicated only one difference: members of the researcher-initiated coalition had higher ratings of perceived action committee effectiveness than did members of the community-initiated coalition. The results suggest that the impetus for initiation and primary purpose of a coalition may not be as important as other factors in influencing immediate process and activity outcomes. During the past decade, the development of coalitions has been assumed to be central to the structure and functioning of a variety of community health promotion and disease prevention projects (

Exposure to tobacco and alcohol advertising has been associated with adolescent substance use. However, it is not clear whether favorable reactions to advertising are an antecedent to or a consequence of substance use. This study investigated relationships between adolescents′ levels of susceptibility to substance use and their recognition and liking of tobacco and alcohol advertising. Method. Eighth-grade students viewed pictures of tobacco and alcohol advertisements with brand names and identifying information obscured, attempted to identify the brand name and type of product being advertised, and rated their liking of the advertisements. Subjects were divided into three substance use status groups: nonsusceptible nonusers (have never used and do not intend to do so), susceptible nonusers (have not used but have not made a firm commitment not to experiment in the future), and users (have tried the substance). Results. Susceptible nonusers liked the tobacco advertisements at a level that was significantly greater than that of the nonsusceptible nonsmokers and comparable to that of the users. Liking of the alcohol advertisements generally increased with alcohol use status. Conclusions. These results suggest that tobacco advertisements ostensibly targeted to adult smokers may have the effect of recruiting new adolescent smokers.

Methods: The present study investigated use of a matrix measure approach among former alternative high school youth (average age = 19.8 years) at risk for addictions. Lifetime and last 30-day prevalence of one or more of 11 addictions reviewed in other work (Sussman, Lisha & Griffiths, 2011) was the primary focus (i.e., cigarettes, alcohol, other/hard drugs, eating, gambling, Internet, shopping, love, sex, exercise, and work). Also, the co-occurrence of two or more of these 11 addictive behaviors was investigated. Finally, the latent class structure of these addictions, and their associations with other measures, was examined. Results: We found that ever and last 30-day prevalence of one or more of these addictions was 79.2% and 61.5%, respectively. Ever and last 30-day co-occurrence of two or more of these addictions was 61.5% and 37.7%, respectively. Latent Class Analysis suggested two groups: a generally Non-addicted Group (67.2% of the sample) and a "Work Hard, Play Hard"-addicted Group that was particularly invested in addiction to love, sex, exercise, the Internet, and work. Supplementary analyses suggested that the single-response type self-reports may be measuring the addictions they intend to measure. Discussion and Conclusions: We suggest implications of these results for future studies and the development of prevention and treatment programs, though much more validation research is needed on the use of this type of measure.

This study investigates the relationship between a specific counselor behavior, valenced reflective listening, and client change talk in a MI intervention with substance-using adolescents. A combination of recorded in-person and telephone (n = 223) sessions were sequentially coded using the Motivational Interviewing Skill Code 2.5. Reflections were categorized by valence, meaning they included content that was either moving toward (i.e., positive reflection) or away from change (i.e., negative reflection). Client language was coded as either moving toward change, away from change, or neutral about change. Probability analyses showed positive reflections were 11 times more likely to be followed by change talk and 71% less likely to be followed by counter change talk. Negative reflections were 19 times more likely to be followed by counter change talk and 65% less likely to be followed by change talk. Client language was also predictive of counselor reflections, such that positive reflections were 10 times more likely to occur after client change talk and negative reflections were 19 times more likely to follow counter change talk. Because the percentage of change talk expressed in a session has been shown to be positively related to improved behavioral outcomes, counselors should avoid unintentional reflections of counter change talk and use reframing techniques to change the valence of client change language. Implications for MI practice and training are discussed.

Methods: Alternative high school students (N = 1676) completed self-report surveys. Cross-sectional data were analyzed via Preacher and Hayes' procedures for multiple mediation. Results: The positive relationship between depressive symptoms and sleep problems was mediated partially by anger coping (positively related to sleep problems). The positive relationship between perceived stress and sleep problems was not mediated by coping strategies. Conclusions: Findings provide information on psychological factors that may lead to poor sleep outcomes, and are useful for developing health promotion interventions to impact lifelong health behaviors.

In our previous cross-sectional study, poor social self-control was found to be associated with higher drug use, controlling for 12 personality disorder categories. In this study, we attempted to find out (a) whether lack of social self-control predicted drug use one year later, and (b) whether drug use at baseline predicted social self-control one year later.

Articles were identified through December 2012 using a search of PubMed, PsychINFO and OVID/Medline databases, using the following keywords in varying combinations: home, environment, availability, vegetable, intake, consumption, children. Quantitative studies examining home vegetable availability and vegetable intake in children and adolescents were included. Fifteen studies were included that met inclusion criteria. Studies were conducted in the USA (n 8), Australia (n 1), Greece (n 1), Iceland (n 1), Denmark (n 1), the UK (n 1), the Netherlands (n 1) and a combination of nine European countries (n 1). Various populations of children and adolescents were examined. Seven of the studies (47 %) found a positive association between vegetable availability and intake, with the others reporting null findings. There were no clear patterns of association by study design, age of subjects included, comprehensiveness of measures, or inclusion of covariates in analyses. Child report of home availability was associated with child vegetable intake (n 6, all found a positive association), while parent report of home availability was only minimally associated (n 9, one found a positive association; P=0.001 from post hoc Fisher's exact test comparing parent v. child report). Parent perception of availability may be closer to truth, given the parental role in food shopping and preparation. Therefore, to impact child vegetable intake, absolute availability may not be as important as child perception of vegetables in the home. Child perception of availability may be altered by level of familiarity with vegetables.

A written questionnaire was completed by 182 law enforcement officials representing 200 cities and counties in California (some officials represented multiple jurisdictions). Logistic regression analyses were conducted to identify factors associated with conducting compliance checks. Only 36% of local enforcement agencies reported conducting one or more compliance checks in the previous year. Agencies were more likely to conduct compliance checks if they perceived fewer barriers to enforcement, reported more frequent collaboration with other community agencies to enforce youth access laws, and believed that youth access to tobacco is a problem in their community. Because active enforcement of youth access laws using unannounced compliance checks has been shown to reduce the rate of illegal tobacco sales to minors and may reduce youth smoking, efforts to increase the level of enforcement should be promoted. These study results may be used to inform efforts to encourage local agencies to enforce existing youth access laws.

Two theoretical content components of the program were examined to increase our understanding of the relative contribution of each to the effectiveness of the program. were randomly assigned to one of three conditions: cognitive perception information curriculum, cognitive perception information + behavioral skills curriculum, or standard care (control). The curricula were delivered to high school students (n=2734) by project health educators and regular classroom teachers. Program effectiveness was assessed with both dichotomous and continuous measures of 30-day substance use at baseline and one-year follow-up.

The present paper describes the immediate outcomes of a dissemination and implementation trial of Project Toward No Drug Abuse, an evidence-based prevention program for high school students. A total of 65 high schools in 14 school districts across the USA were recruited and randomly assigned to one of three experimental conditions: comprehensive implementation support for teachers, regular workshop training only, or standard care control. The comprehensive intervention was comprised of on-site coaching, web-based support, and technical assistance, in addition to the regular workshop. Students (n=2,983) completed selfreport surveys before and immediately after program implementation. Fidelity of implementation was assessed with a classroom observation procedure that focused on program process. Results indicated that relative to the controls, both intervention conditions produced effects on hypothesized program mediators, including greater gains in program-related knowledge; greater reductions in cigarette, marijuana and hard drug use intentions; and more positive changes in drug-related beliefs. There were stronger effects on implementation fidelity in the comprehensive, relative to the regular, training condition. However, seven of the ten immediate student outcome measures showed no significant differences between the two training conditions. The implications of these findings for dissemination research and practice are discussed.

A written questionnaire was completed by 182 law enforcement officials representing 200 cities and counties in California (some officials represented multiple jurisdictions). Logistic regression analyses were conducted to identify factors associated with conducting compliance checks. Only 36% of local enforcement agencies reported conducting one or more compliance checks in the previous year. Agencies were more likely to conduct compliance checks if they perceived fewer barriers to enforcement, reported more frequent collaboration with other community agencies to enforce youth access laws, and believed that youth access to tobacco is a problem in their community. Because active enforcement of youth access laws using unannounced compliance checks has been shown to reduce the rate of illegal tobacco sales to minors and may reduce youth smoking, efforts to increase the level of enforcement should be promoted. These study results may be used to inform efforts to encourage local agencies to enforce existing youth access laws.

Two theoretical content components of the program were examined to increase our understanding of the relative contribution of each to the effectiveness of the program. were randomly assigned to one of three conditions: cognitive perception information curriculum, cognitive perception information + behavioral skills curriculum, or standard care (control). The curricula were delivered to high school students (n=2734) by project health educators and regular classroom teachers. Program effectiveness was assessed with both dichotomous and continuous measures of 30-day substance use at baseline and one-year follow-up.

The present paper describes the immediate outcomes of a dissemination and implementation trial of Project Toward No Drug Abuse, an evidence-based prevention program for high school students. A total of 65 high schools in 14 school districts across the USA were recruited and randomly assigned to one of three experimental conditions: comprehensive implementation support for teachers, regular workshop training only, or standard care control. The comprehensive intervention was comprised of on-site coaching, web-based support, and technical assistance, in addition to the regular workshop. Students (n=2,983) completed selfreport surveys before and immediately after program implementation. Fidelity of implementation was assessed with a classroom observation procedure that focused on program process. Results indicated that relative to the controls, both intervention conditions produced effects on hypothesized program mediators, including greater gains in program-related knowledge; greater reductions in cigarette, marijuana and hard drug use intentions; and more positive changes in drug-related beliefs. There were stronger effects on implementation fidelity in the comprehensive, relative to the regular, training condition. However, seven of the ten immediate student outcome measures showed no significant differences between the two training conditions. The implications of these findings for dissemination research and practice are discussed.
