Asians consistently report higher social anxiety symptoms but have lower prevalence rates, compared to Westerners. As cultural differences and measurement issues could both be potential sources for the discrepancy, it is important to examine whether score differences between cultural groups are due to measurement issues or genuine underlying differences in social anxiety. This study used 402 participants to examine the construct of social anxiety and measurement invariance of six social anxiety scales using exploratory and confirmatory factor analysis. Results supported scalar invariance of a three-factor bifactor model (comprised of Fear/Avoidance of Social Interaction, Fear of Negative Evaluation, and Taijin Kyofusho/fear of interpersonal relationships). Furthermore, multivariate analysis of covariance and moderation analysis revealed Asian Americans endorsed higher Fear/Avoidance of Social Interaction symptoms, but do not differ in Taijin Kyofusho and Fear of Negative Evaluation symptoms, compared to European Americans. This study showed when measurement bias is minimized, Asians still endorse higher symptoms of Fear/Avoidance of Social Interactions. Moreover, Taijin Kyofusho appears to be an aspect of social anxiety identified in more than one cultural group rather than a culture-related specific syndrome. Thus, it is important for clinicians and researchers to consider Taijin Kyofusho in the evaluation of social anxiety. / School Psychology

The present study examined the role of emotion regulation (ER) in individuals who endorsed social anxiety symptoms found in taijin kyofusho (TKS) and social anxiety disorder (SAD) in a young adult sample. More specifically, the study sought to examine the role of self-conscious emotions of shame and embarrassment with respect to TKS and SAD. Participants were administered a series of questionnaires during the first phase of the study and, during the second phase, a diagnostic clinical interview and additional questionnaires were administered along with an experimental social evaluative task and recording of electrical cardiac impulses. Descriptively, social anxiety symptoms were expected to be associated with less adaptive ER strategies. Additionally, differences between individuals who endorsed TKS and SAD symptoms were expected such that TKS would be associated more so with shame and SAD with embarrassment. It was hypothesized that ER would mediate the relationship between embarrassment and shame and their hypothesized anxiety counterparts (SAD or TKS). Findings revealed an association between shame and TKS, and embarrassment and SAD. However, less adaptive ER strategies were not related to social anxiety symptoms and ER did not mediate the relationship between self-conscious emotions and social anxiety. The present findings suggest that shame and embarrassment can play a role in the clinical manifestations of SAD and TKS. Implications regarding the role of these emotions and ER were examined. / Ph.
