The InterSECT Framework: a proposed model for explaining population-level trends in substance use and emotional...

Area of Science:

• Public Health
• Adolescent Psychology
• Substance Use Research

Background:

• Rising prevalence of adolescent emotional concerns in high-income countries over two decades.
• General decline in adolescent substance use, with unclear links to emotional health trends.
• Mixed findings and inconsistent messaging regarding co-occurring substance use and emotional concerns in adolescents.

Purpose of the Study:

• To introduce the InterSECT Framework for understanding the intersection of trends in adolescent substance use and emotional concerns.
• To provide a theoretical structure for evaluating changes in the co-occurrence of these two phenomena.
• To guide future research and conceptualization of adolescent mental health and substance use patterns.

Main Methods:

• Development of a theoretical framework (InterSECT Framework).
• Identification and discussion of three core hypotheses: hardening, consistency, and decoupling.
• Integration of existing research and youth perspectives to inform a research agenda.

Main Results:

• The InterSECT Framework offers a structured approach to analyze complex trends.
• The framework accommodates hypotheses of strengthening, stable, or weakening co-occurrence.
• It highlights the need for nuanced research into the relationship between adolescent emotional health and substance use.

Conclusions:

• The InterSECT Framework provides a novel conceptual tool for researchers and policymakers.
• It facilitates a clearer understanding of evolving patterns in adolescent substance use and emotional well-being.
• The framework supports the development of targeted interventions and research strategies.
