This study examined the role of friendship networks and peer influences in body image concern, dietary restraint, extreme weight loss behaviours (EWLBs) and binge eating in a large community sample of young adolescent females. Based on girls' self-reported friendship groups, social network analysis was used to identify 173 friendship cliques. Results(More)
Over the past five years, the release of cohort studies assessing the link between cannabis and psychosis has increased attention on this relationship. Existing reviews generally conclude that these cohort studies show cannabis has a causal relationship to psychosis, or at least that one cannot be excluded.

BACKGROUND Debate continues about the consequences of adolescent cannabis use. Existing data are limited in statistical power to examine rarer outcomes and less common, heavier patterns of cannabis use than those already investigated; furthermore, evidence has a piecemeal approach to reporting of young adult sequelae. We aimed to provide a broad picture of(More)
This 2006 study examined 1) whether maternal use of tobacco and consumption of alcohol when a child is 5 and 14 years of age predict cannabis use in young adults, and 2) whether this association is explained by possible confounding or mediating factors. Data were taken from a prospective birth cohort study of mothers and their children in Brisbane,(More)

However, no studies to date have attempted to disentangle the underlying peer selection and socialization processes that may explain this homophily. The current study used longitudinal stochastic actor-based modeling(More)
Although major etiological models highlight the importance of friends in the development of adolescent body image and eating problems, longitudinal research that comprehensively investigates possible direct and mediational relationships between these variables is lacking. Thus, this study aimed to examine prospective interrelationships between perceived(More)
