Positive emotional reactivity to pleasant social and nonsocial stimuli in social anxiety disorder.

Prior research has shown that Social Anxiety Disorder (SAD) is associated with significantly diminished positive affect (PA). Few studies have examined PA reactivity to pleasant experimental stimuli in individuals with SAD and whether emotional responses might be moderated by social context. Here, we investigated repeated measures of PA reactivity among individuals with SAD (n = 46) and healthy controls (HC; n = 39) in response to standardized neutral images, pleasant music, and social versus nonsocial guided imagery. Primary analyses revealed that SAD and HC participants did not differ in their PA reactivity when PA was conceptualized as a unitary construct. Exploratory analyses examining discrete subfacets of PA revealed potential deficits for SAD participants in relaxed and content PA, but not activated PA. Although participants with SAD reported relatively lower levels of relaxed and content PA overall compared with controls, they exhibited normal increases in all PA subfacets in response to pleasant music as well as pleasant social and nonsocial stimuli. These findings support a more nuanced conclusion about PA deficits in SAD than is described in the extant literature, suggesting that detecting PA deficits in SAD may depend upon how PA is conceptualized, evoked, and measured.
