Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay the onset and escalation of use are needed. The risk and promotive factors approach to substance use prevention is a well-established framework for identifying the timing and targets for prevention initiatives. This study…

Runaway and homeless youth often have a constellation of background behavioral, emotional, and familial problems that contribute to stress and maladaptive behaviors, which, in turn, can lead to self-harming and suicidal behaviors. The current study examined the roles of stress and maladaptive behaviors as mediators between demographic and…

In a recent study, de Araujo and Murray (2010) find empirical evidence that living on campus leads to improved student performance, finding both immediate effects (GPA improves while the student lives on campus) and permanent effects (GPA remains higher even after moving off campus). Using the same dataset, we extend the analysis to explain why…

Scientists, educators, and parents of teens have long recognized the potency of peer influences on children and youth, but until recently, questions of how and why adolescents emulate their peers were largely overlooked. This book presents a framework for understanding the processes by which peers shape each other's attitudes and behavior, and…

This paper examines the hypothetically bi-directional relationship which links marijuana consumption and school failure among students. To that end, we propose a simultaneous probability model, which is estimated by using the information provided by the three consecutive waves from the Spanish Surveys on Drug Use in the School Population [(1996,…

Evaluates a social development model of psychosocial predictors of drug use in Anglo and Hispanic children and adolescents. Structural equation models reveal that patterns and predictors of drug use are distinct for each sub-group, by age and ethnicity. Later drug use was primarily associated with prior use, exposure to parental and peer models of…

Many questions about the associations between risk factors and drug use remain unanswered. Data originally obtained from seventh graders participating in a school-based prevention program were examined in terms of a theoretical model. A series of multiple regression analyses were then conducted to select those risk factors which contributed unique…

Explores the interplay of various factors that may jointly predict the frequency of drug use and the intention for further use. Drug-use prevalence data for 969 adolescents, high school students, and imprisoned offenders linked drug-use frequencies with psychosocial variables such as disinhibition, peer drug use, peer pressure, and other factors.…

Tested relevance of risk-factor model for predicting drug use among rural seventh graders (n=235). Nineteen of 20 risk factors were significantly related to at least 1 category of drug use. Subset of 10 risk factors was significantly associated with prevalence and frequency of use of cigarettes, beer and wine, hard liquor, marijuana, and other…

Examined knowledge about medicines and perceived benefit among 101 children, ages 7 and 10. Found that medicine knowledge was explained using age, educational environment, and degree of internal locus of control as significant predictors. The negative effect of internal locus of control predicted perceived benefit. Retention of drug advertising…

Data focused on illegal alcohol and marijuana use were collected in 1981 from 4,859 high school students living in two rural counties in southern Georgia. The sample consisted of over 85% of all students in grades 8 through 12 within the two counties. The data were used to test a facilitative-constraint model developed from selected components of…

Addresses the use of data sources and multivariate data analysis methods for modeling naturally occurring data. Two studies in this special section deal with longitudinal perspectives on drug use and emotional adjustment and an application of log-linear model to examine the stress-buffering function of alcohol.

Three models reflecting stages of substance abuse were tested using path analysis with subsamples of 626 to 850 subjects. Models indicate that measures of religiosity and religious conservatism help explain substance use. Results suggest that explanations of substance abuse can be enhanced through models using stage of drug involvement. (SLD)

This study examined antecedents to early patterned alcohol and tobacco use and marijuana experimentation between ages 11 and 16 for an at-risk male sample. Findings suggested that family, peer, and child characteristics were inextricably connected within an ecology of development. A structural equation prediction model suggested a higher order…
