Conviction subtype Taijin-Kyofu (c-TK) is a subgroup of mental disorder characterized by conviction and strong fear of offending others in social situations. Although the concept of c-TK overlaps with that of social anxiety disorder (SAD), patients with c-TK often may not be diagnosed as such within the current Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria. We propose the Nagoya-Osaka criteria to amend this situation. This study examined the cross-cultural interrater reliability of the proposed criteria. Eighteen case vignettes of patients with a variety of complaints focused around social anxieties were collected from 6 different countries, and diagnosed by 13 independent raters from various nationalities according to the original DSM-IV and the expanded criteria. The average agreement ratio for the most frequent diagnostic category in each case was 61.5% with DSM-IV and 87.6% with the modified DSM-IV with Nagoya-Osaka criteria (p < 0.001). These findings indicate that the Nagoya-Osaka criteria for SAD can improve interrater reliability of SAD.
