Identifying Sensitive Periods When Changes in Parenting and Peer Factors Are Associated with Changes in Adolescent Alcohol and Marijuana Use

Abstract There are well-established associations between parental/peer relationships and adolescent substance use, but few longitudinal studies have examined whether adolescents change their substance use in response to changes in their parents' behavior or peer networks. We employ a within-person change approach to address two key questions: Are changes in parenting and peer factors associated with changes in adolescent marijuana and alcohol use? Are there sensitive periods when changes in parenting and peer factors are more strongly associated with changes in adolescent marijuana and alcohol use?

An Examination of Parental and Peer Influence on Substance Use and Criminal Offending During the Transition from Adolescence to Adulthood

Abstract Although peer behavior and parent-child-conflict have been associated with adolescent and young adults' behavior, prior studies have not adequately controlled for selection effects and other confounders, or examined whether associations change across the transition to adulthood or by race. Using annual data from young men followed from 17-26, within-individual change models examined whether substance use or offending increased in the year after boys began affiliating with friends who engaged in substance use/offending and/or experienced increased parent-son-conflict.

When Psychopathology Matters Most: Identifying Sensitive Periods When within-Person Changes in Conduct, Affective, and Anxiety Problems Are Associated with Male Adolescent Substance Use

Abstract BACKGROUND AND AIMS There is a documented link between common psychiatric disorders and substance use in adolescent males. This study addressed two key questions: (1) is there a within-person association between an increase in psychiatric problems and an increase in substance use among adolescent males and (2) are there sensitive periods during male adolescence when such associations are more evident? DESIGN Analysis of longitudinal data collected annually on boys selected randomly from schools based on a comprehensive public school enrollment list from the Pittsburgh Board of Education.
