Binge Drinking in Adolescence and Early Adulthood: The Salience of PTSD and PTSD-Linked Strain Sensitivity from a Developmental Perspective

Abstract

Background: Post-traumatic stress disorder (PTSD) has been identified by past research as a risk factor for substance use. Further, past research has indicated that individuals with PTSD may demonstrate an increased sensitivity to strain. Despite this, no study has examined the relevance of these processes for understanding binge drinking behaviors from a developmental perspective. Purpose/Objectives: Understand the relevance of PTSD-linked strain sensitivity for predicting binge drinking in adolescence and adulthood. Methods: This study utilizes data from the Pathways to Desistance study, comprising the responses of 1354 juvenile offenders across seven years following an adjudication. A series of ordinal logistic regression models estimated these effects in adolescence and early adulthood. Results: Results indicate that adolescent PTSD interacted with witnessed violence to produce lower frequency binge drinking. This effect was non-significant in early adulthood. Conclusions/Importance: These findings indicate that adolescent PTSD-sufferers demonstrate diminished sensitivity to witnessed violence. This may have to do with adolescence social processes.
