Abstract
Background: Emotional dysregulation, measured with face recognition tasks, is prevalent in alcohol use disorders (AUD), constituting a risk factor for alcohol use and relapse. It is not clear however whether emotional dysregulation is a by-product of alcohol consumption, or if it can act as a predisposing factor for AUD. Objective: Our aim was to examine early signs of emotional dysregulation in adolescent drinkers. Method: Twenty-four high-school students and 24 university students completed two tasks. On the first one, participants had to gradually increment the emotional content of different faces until they could perceive an emotional expression (emotion perception threshold task). We also examined the propensity to perceive fearful expressions in an emotion identification task. Participants were semantically primed with emotion words (i.e., "fear"), and they then had to indicate whether a neutral-fearful facial composite matched the prime. Results: Using repeated-measures ANOVAS, in the emotion perception threshold task, "happy" faces were the easiest to detect and "sad" ones the hardest. For high school students there was a differential response pattern depending on binge scores, such that High-binge drinkers found it easier to detect a sad face but harder to detect a happy one compared to Low-binge drinkers. In the facial emotion identification task, Low-binge drinkers observed more fearful expressions compared to High-binge drinkers. Conclusions: Differences in emotional processing in young adolescents depending on drinking habits point towards the relevance of emotional dysregulation as an early sign of AUD. These findings could help develop novel diagnostic and treatment tools for young populations.
