Anxiety Disorders in the DSM-5: Changes, Controversies, and Future Directions

To examine cultural aspects in social anxiety and social anxiety disorder (SAD), we reviewed the literature on the prevalence rates, expressions, and treatments of social anxiety/SAD as they relate to culture, race, and ethnicity. We further reviewed factors that contribute to the differences in social anxiety/SAD between different cultures, including individualism/collectivism, perception of social norms, self-construal, gender roles, and gender role identification. Our review suggests that the prevalence and expression of social anxiety/SAD depends on the particular culture. Asian cultures typically show the lowest rates, whereas Russian and US samples show the highest rates, of SAD. Taijin kyofusho is discussed as a possible culture-specific expression of social anxiety, although the empirical evidence concerning the validity of this syndrome has been mixed. It is concluded that the individual's social concerns need to be examined in the context of the person's cultural, racial, and ethnic background in order to adequately assess the degree and expression of social anxiety and SAD. This has direct relevance for the upcoming DSM-V. © 2010 Wiley-Liss, Inc.

Judgmental biases for threat-relevant stimuli are thought to be important mechanisms underlying the etiology and maintenance of anxiety disorders. The authors hypothesized (a) that people with generalized social phobia (GSP) would rate negative social events but not nonsocial events as more probable and costly than would nonanxious controls (NACs) and (b) that cognitive behavioral treatment would decrease probability and cost estimates for social but not nonsocial events. Participants with GSP and NACs were assessed twice, 14 weeks apart, during which the former received cognitive behavioral therapy. Those with GSP evidenced socially relevant judgmental biases prior to treatment, and these were attenuated following treatment. Reduction in cost estimates for social events, but not in probability estimates, mediated improvement in social phobia. Results are discussed in light of emotional processing theory.

Social phobics, anxious controls and non-patient controls took part in a brief videotaped conversation with a stooge in order to investigate the cognitive model of social phobia. Thoughts, behaviour, and attention during the conversation were assessed. Compared to the control groups, social phobics had more negative self-evaluative thoughts, performed less well, and systematically underestimated their performance. There were no differences in attention between the three groups. Content analysis of thought sampling data from the conversation, and from three hypothetical situations, revealed that few of the negative thoughts reported by social phobics explicitly mentioned evaluation by other people. This suggests that social phobics may not closely monitor other people's responses in social situations and hence that their thoughts are not data driven. The results are discussed in relation to the cognitive model of social phobia and suggestions are made for improvements in the treatment of social phobia.
