[Psychoactive substance abuse, behavioral disorder and depression during adolescence.]

Area of Science:

• Adolescent psychology
• Developmental psychopathology
• Mental health research

Context:

• Adolescence presents significant adaptation challenges.
• Co-occurrence of psychotropic drug abuse, behavioral disorders, and depression is common.
• Understanding childhood predictors of adolescent adaptation problems is vital.

Purpose:

• To examine the co-occurrence of psychotropic drug abuse, behavioral disorders, and depression in adolescents.
• To identify childhood behavioral, social, and family characteristics differentiating adolescents with multiple vs. single/no adaptation problems.
• To inform preventive interventions for at-risk youth.

Summary:

• A study of over 1600 Quebec adolescents (mean age 15.7) analyzed the co-occurrence of substance abuse, behavioral disorders, and depression.
• Childhood characteristics (ages 6-12) were assessed via parent/teacher questionnaires.
• Nearly 10% of adolescents had two or three problems, distinguishing them from those with fewer issues, except for substance abuse alone.

Impact:

• Findings highlight the importance of recognizing simultaneous adolescent adaptation problems.
• Identifies specific childhood risk factors for multiple adaptation issues.
• Supports the development of targeted, preventive interventions for adolescents at risk.
