Testing the dual pathway hypothesis to substance use in adolescence and young adulthood.
ABSTRACT We tested the dual pathway hypothesis to substance use which posits that substance use can develop via internalizing symptoms or deviant behaviors.
Using data from the Add Health study, we used latent class analysis to define subgroups based on patterns of substance use, and logistic regression procedures to evaluate the prospective association between symptoms of depression, deviance, and the individual substance use patterns.
Groups representing similar patterns of substance use were identified in both adolescence and young adulthood. Some support for the dual pathway hypothesis was demonstrated. Deviance was prospectively associated with substance group assignment in both adolescence and young adulthood, while depression uniquely predicted assignment to the smoking group in young adulthood among females.
Further testing of the dual pathway hypothesis should be built on diverse pattern-centered approaches able to explore the presence of population subgroups.

ABSTRACT: To date studies have not explored patterns of substance use exclusively among youth in the child welfare system. Consequently, little is known about polysubstance use among child welfare-involved youth. This study aimed to explore whether physical abuse, parental substance use, depression, and demographic characteristics predict distinct patterns of substance use among child welfare-involved youth using latent class analysis (LCA). The sample included 822 11–17 year olds who participated in the National Survey of Child and Adolescent Well-being (NSCAW II) study between March 2008 and September 2009. We found the following three classes: (1) polysubstance use, (2) alcohol and marijuana use, and (3) low use. Older youth and youth who experienced physical abuse were at greater risk of being in the polysubstance use class, while living with a biological parent reduced the likelihood of polysubstance use class membership. Youth in the alcohol and marijuana use class were more likely to be older and depressed. Results from this study illuminate important targets for interventions.Substance Use & Misuse 10/2014; DOI:10.3109/10826084.2014.966845 · 1.23 Impact Factor

ABSTRACT: Despite evidence that many Australian adolescents have considerable experience with various drug types, little is known about the extent to which adolescents use multiple substances. The aim of this study was to examine the degree of clustering of drug types within individuals, and the extent to which demographic and psychosocial predictors are related to cluster membership. A sample of 1402 adolescents aged 12-17years were extracted from the Australian 2007 National Drug Strategy Household Survey. Extracted data included lifetime use of 10 substances, gender, psychological distress, physical health, perceived peer substance use, socioeconomic disadvantage, and regionality. Latent class analysis was used to determine clusters, and multinomial logistic regression employed to examine predictors of cluster membership. There were 3 latent classes. The great majority (79.6%) of adolescents used alcohol only, 18.3% were limited range multidrug users (encompassing alcohol, tobacco, and marijuana), and 2% were extended range multidrug users. Perceived peer drug use and psychological distress predicted limited and extended multiple drug use. Psychological distress was a more significant predictor of extended multidrug use compared to limited multidrug use. In the Australian school-based prevention setting, a very strong focus on alcohol use and the linkages between alcohol, tobacco and marijuana are warranted. Psychological distress may be an important target for screening and early intervention for adolescents who use multiple drugs.Addictive behaviors 04/2013; 38(4):2068-73.

ABSTRACT: Purpose – The purpose of this paper is to investigate the association between mother-child and father-child communication and children's life satisfaction, and the moderating effect of communication with stepparents. Design/methodology/approach – Data from the 2006 Health Behaviour in School-aged Children: WHO-collaborative Study in Scotland (n ¼ 4; 959) were analysed using multilevel linear regression analyses. Findings – There was an association between both mother-child and father-child communication and young people's life satisfaction. Relationship with mother was particularly important, especially among girls. Among boys, not living in a traditional two-parent family was a predictor of low life satisfaction, even when communication with one or more parents was easy. This effect was independent of economic disadvantage. The quality of the relationship with stepparents moderated these associations very slightly and in single father families only. Research limitations/implications – Strategies at the population level are recommended to enhance an open atmosphere in the home where young people feel they are able to talk to their parents about things that are bothering them. Further work is needed to understand the needs of high risk groups such as boys living in single father households and girls living in single mother and step families. Originality/value – The mental well-being of children and adolescents is a priority area for the World Health Organization and the Scottish Government but is a relatively new field with little known and no measures as yet identified. This study considered the impact of determinants related to the family on adolescent life satisfaction. The context of lone father families, an often missed category, was considered, as was the moderating effect of step-parents.Health Education 01/2010; DOI:10.1108/09654281011038831
