The neglected relationship between social interaction anxiety and hedonic deficits: differentiation from depressive symptoms

Depressive symptoms are associated with both the presence of negative subjective experiences and relative absence of positive subjective experiences. A similar affective profile of high negative affect and low positive affect (PA) has been associated with excessive social anxiety (SA). This initial cross-sectional study evaluated the incremental effects of social interaction anxiety on hedonic deficits beyond the effects of depressive and anxiety (i.e., physiological arousal, worry) symptoms. From a sample of 97 college students, a factor analysis on self-report measures of hedonic functioning derived two domains: Positive Subjective Experiences and Curiosity. Social interaction anxiety was uniquely, negatively related to Positive Subjective Experiences and Curiosity after removing variance attributable to various depressive and anxiety symptoms. In contrast, anxious arousal and nonspecific anxiety had near-zero relationships with both domains, and depressive symptoms were negatively related to Positive Subjective Experiences. These data provide some evidence for an association between social interaction anxiety and hedonic deficits that is not attributable to covariance with other internalizing conditions.
