RADAR study: protocol for an observational cohort study to identify early warning signals on the pathways to alcohol use disorder

INTRODUCTION: Harmful alcohol consumption, particularly alcohol use disorder (AUD), is a worldwide health priority, contributing substantially to global morbidity and mortality. The peak age of onset of AUD is 18-24, thus a deeper understanding of the young adult experience is vital if we are to identify modifiable risk factors and intervene early in the developmental course of this disabling disorder. Critical unanswered questions include: How soon after drinking initiation do AUD symptoms begin to emerge? Which symptoms come first? Do the symptoms unfold in a predictable pattern?

Trajectories of emotional symptoms in adolescence: impact on alcohol use

Purpose: The purpose of this paper is to explore how different trajectories of emotional symptoms relate to alcohol use in adolescence. Design/methodology/approach: In all, 431 participants (majority female), aged approximately 13 years at baseline were followed over three years and reported on their emotional symptoms and alcohol use. Latent class growth analyses explored different trajectories of emotional symptoms and regression models were run to relate these trajectories to alcohol use (full standard drink, and binge drinking) at 36-month follow-up (age 16 years).
