Genetic and psychosocial predictors of alcohol use trajectories among disaster-exposed adolescents.

ABSTRACT:

Background and objectives

Adolescent alcohol misuse is associated with numerous long-term adverse outcomes, so we examined predictors of alcohol use among disaster-exposed adolescents, a group at-risk for alcohol misuse.

Methods

The current study (n = 332) examined severity of tornado-related exposure, posttraumatic stress disorder (PTSD) symptoms, emotional support, and a genetic risk sum score (GRSS) as predictors of alcohol use trajectories.

Results

Severity of exposure interacted with the GRSS to predict both intercept (12-month follow up quantity of alcohol use) and growth rate. Emotional support also interacted with adolescent PTSD symptoms to predict intercept and growth rate.

Discussion and conclusions

Adolescents with greater severity of disaster expos
