[Substance use in adolescents: the role of stress, impulsivity, and schemas related to lack of limits].
The aim of this study was to assess the association between stress, cognitive schemas, impulsivity, and substance use in adolescents. A sample of 657 adolescents (367 girls and 290 boys) completed measures of stressful life events, cognitive schemas of grandiosity and insufficient self-control, impulsive style of problem-solving and substance use. The results indicated that stressful life events and the cognitive schemas were significantly associated with substance use. In addition, the impulsive style of problem-solving moderated the relationship between stressors and substance use, this association being stronger among more impulsive adolescents. Finally, the results indicated that boys scored higher on Grandiosity and on the use of marijuana, cocaine, LSD and ecstasy, while girls scored higher on tobacco use (smoking). Despite these differences, gender did not moderate the association between schemas and substance use.
