While the psychosocial difficulties associated with one specific type of social withdrawal, shyness, have been extensively studied, less is known about the correlates of other subtypes, such as preference-for-solitude. Of the existing studies on withdrawal subtypes, few focus on the emerging adulthood developmental period, and none have examined possible physical health-related correlates and associated mechanisms. This study considered whether two withdrawal subtypes (shyness, preference-for-solitude) are associated with emotional eating vis-à-vis internalizing problems during emerging adulthood. Participants included 643 emerging adults (283 males; M age = 19.61) who completed measures of withdrawal subtypes, emotional eating, and internalizing problems (depression, loneliness, social anxiety). Path models revealed that the associations between both shyness and preference-for-solitude and emotional eating were explained, in part, by depression and social anxiety. Findings suggest that withdrawing from peers during emerging adulthood, due to fear or preferences-for-solitude, may have significant consequences for both physical health outcomes vis-à-vis psychological difficulties.
