Key Points

This pilot study aims to characterize neural markers of reward sensitivity and explore their relation to peer victimization and anhedonia during social stress.
Included 15 socially anxious adolescents who completed self-report questionnaires and an MRI scan during the Island Getaway task.
Analyzed ventral striatum BOLD signal activation during anticipation of social feedback and its outcome.
Examined relationships between peer victimization and neural activation outcomes.
Socially anxious adolescents showed significantly suppressed VS activation during negative feedback anticipation (p<0.05).
Reduced VS activation correlated with increased anhedonia scores (p<0.01).
Relational peer victimization was linked to further suppression of VS activation (HR=0.75, 95% CI 0.65-0.85, p<0.01).
