AIMS To develop and test a non-recursive model that examines the effects of parental psychoactive substance use disorder (PSUD) on the reciprocal relationships among stressful life events, family attachment, peer drug use and adolescent drug use. DESIGN A 3-year prospective cohort study followed adolescents from three types of families defined by a(More)
The purpose of this paper is to describe and examine one pathway by which adolescent drug use increases during early and mid-adolescence. It draws upon recent research on adolescent stress, drug use, and family processes to describe an important stage of the life course. A chief principle underlying the proposed pathway is that the cumulative effect of(More)
Stressful life circumstances have myriad influences on human health and behavior. Early research focused on the variable distribution of stress and its effects by socioeconomic status, race, and gender. More recent research indicates that variation by age is also an important consideration. For example, adolescent reactions to stressful life events are(More)
This study examined familial, interpersonal, and intrapersonal factors associated with adolescent drug use from both developmental and etiological perspectives. Retrospective case-control and prospective longitudinal designs were used. A multivariate analysis of variance with repeated measures design was conducted to examine changes over time and(More)
Studies indicate that HIV risk behaviors vary greatly among injection drug users (IDUs). The source of such variation is often ascribed to individual differences, but much of it is due to how IDUs are grouped into social networks. Nevertheless, given the turbulent and uncertain lives led by many IDUs, it would not be surprising if their social networks(More)
Fission yeast nuc2+ gene encodes a protein of a tetratricopeptide repeat (TPR) family which is conserved throughout evolution. We previously showed that nuc2 is required for exit from the mitotic metaphase. In this study, we present evidence which shows that nuc2 has two additional roles in the cell cycle. We showed that the nuc2 mutant is sterile even at(More)
The purpose of this study is to determine the impact of different modes of data collection on the reliability of self-reported drug use of adolescents in a panel study. Adolescents were assigned to four groups based upon the ways they chose to respond to the survey instruments: 1) mailed questionnaires in both years, 2) survey interview in one year and(More)
A retrospective (case control) design was used to compare adolescents in treatment for alcohol and drug problems and their families with adolescents and families not in treatment to determine: (1) the extent to which adolescents' drug-using behavior was associated with greater physical and mental health services utilized by the adolescent and his/her family(More)
Researchers have relied on a number of measurement techniques to construct a summated index of drug involvement to reflect both the qualitative and quantitative dimensions of adolescent drug-using behavior. The purpose of this study was to examine the adequacy of three strategies for constructing a composite measure--stage-of-drug-use, unweighted sum of(More)
