Examining longitudinal associations between polysubstance use and firearm-related risk behaviors from adolescence into emerging adulthood: a group-based multi-trajectory modeling approach.

ABSTRACT:

Introduction

Firearm access and associated risk behaviors (i.e., firearm storage and carriage) are established factors that increase the risk of firearm-related injuries. While extant research has demonstrated associations between singular substance use and these risks, little is known regarding the impact of polysubstance use on these outcomes. The present study aims to investigate the relationships between polysubstance use in adolescence and four specific firearm-related risks manifesting in emerging adulthood.

Methods

Ten years of annual data from a cohort of 1,042 adolescents initially aged 13-18 years were analyzed to identify polysubstance use trajectories and their associations with firearm-related behaviors in emerging adulthood. Using group-based multi-trajectory m
