A self-report questionnaire was administered to high school seniors to collect data on the psychological, behavioral, and social aspects of their lives. It was found that employment was associated with: greater depression; inferior relationships with parents and best friend, including less time and physical contact with parents; lower grade point…

In an on-going debate over the consequences of adolescent employment, there is growing agreement that work intensity (i.e., longer hours) fosters underage drinking and other substance use. The current study furthers our understanding of the relationship between hours of employment and substance use in adolescence by testing whether it is evident…

This study examines the effects of 2 brief family-focused interventions on the trajectories of substance initiation over a period of 6 years following a baseline assessment. The 2 interventions, designed for general-population families of adolescents, were the 7-session Iowa Strengthening Families Program (ISFP) (Molgaard & Spoth, 2001) and the…

Associations among six different domains of self-esteem (peers, school, family, sports/athletics, body image, and global self-worth) and risk behaviors related to substance use and suicidality were investigated in a sample of South African adolescents. Students enrolled in Grades 8 and 11 at independent secondary schools in Cape Town (N = 116)…

A cross-sectional analysis of baseline data collected during a secondary prevention intervention study was conducted to describe patterns of drug use in a non-treatment sample of young drug users recruited in ten further-education colleges across inner London. Participants were 200 young people who were either weekly cannabis users and/or who had…

The study assessed prevalence of volatile substance abuse (VSA), and its link to other forms of psychoactive substance use and to other problem behaviours among 14-15 year olds recruited from sixteen secondary schools in south-west London. Lifetime use of volatile substances was reported by 126 young people (6% of the sample) whose mean age of…

Two hundred regular users of illegal drugs, aged 16-20, were recruited by peers in ten further education colleges across inner London. Data collected by self-completion questionnaire are presented on patterns of cigarette, alcohol, cannabis, stimulant and other drug use among White, Black and Asian ethnic groups. Multiple and logistic regression…

To further develop tailored interventions, their working mechanisms must be identified. In the present study, three tailored messages that each contained one potential working mechanism--personalization, adaptation or feedback--were compared with a standard information condition. Two hundred and two students who smoked tobacco daily were randomly…

The "Anti-Tobacco Media Blitz" (ATMB), a social-norms marketing program, was utilized for tobacco prevention with middle and high school students. University students assisted middle and high school students with the implementation of this campaign, which included a variety of media. Students worked in teams to design, develop, and…

This paper examines the direct and indirect effects of sports participation on perceived health. It is based on a representative sample of middle adolescents aged 15-18 (N=1038, M AGE=16.31, S. D.=0.92; 510 boys and 528 girls) from the Valencian Community (Spain). This study used two different models; Model A is an adaptation of Thorlindsson,…

Disparities in chronic disease risk by occupation call for new approaches to health promotion. WellWorks-2 was a randomized, controlled study comparing the effectiveness of a health promotion/occupational health program (HP/OHS) with a standard intervention (HP). Interventions in both studies were based on the same theoretical foundations. Results…

To address the rise in tobacco use among college students, several national health organizations, including the American College Health Association,recommend that colleges enact smoking bans in and around all campus buildings, including student housing, and prohibit the sale, advertisement, and promotion of tobacco products on campus. Key…

Monitoring the Future is a long-term program of research being conducted at the University of Michigan's Institute for Social Research under a series of investigator-initiated research grants from the National Institute on Drug Abuse. Now in its 33rd year, the study is comprised of several ongoing series of annual surveys of nationally…

This study used semi-parametric group-based modeling to explore unconditional and conditional trajectories of self-reported depressed mood from ages 12 to 25 years. Drawing on data from the National Longitudinal Study of Adolescent Health (N = 11,559), 4 distinct trajectories were identified: no depressed mood, stable low depressed mood, early…

The purpose of this study was to test a conceptual model based on theoretical and empirically supported relationships related to the influences of weight perceptions, weight concerns, desires to change weight, friends, age and location in relation to physical activity (PA) and smoking in adolescents. A total of 1242 males and 1446 females (mean…
