Does Alcohol Initiation in Early-To-Middle Adolescence Predict Changes in Reward Motivation? Evidence of Sex Differences.

ABSTRACT:

Background

Reward motivation has been cross-sectionally correlated with adolescent alcohol use, but the temporal nature of this relationship remains unclear. This project sought to determine whether adolescent alcohol initiation longitudinally predicted changes in reward motivation and behavioral inhibition from early to middle adolescence, and explored the role of adolescent sex in this prediction.

Methods

A total of 180 11- to 14-year-olds were recruited and then followed for 3 years to age 14 to 17. Participants self-reported their alcohol use at all time points. We selected participants who were alcohol-naïve at Baseline (early adolescence) and then grouped them based on whether or not they reported alcohol initiation by Year 3 (Y3: middle adolescence). Adolescents compl
