An investigation of the psychometric properties of the Social Thoughts and Beliefs Scale (STABS) and structure of cognitive symptoms in participants with social anxiety disorder and healthy controls

摘要

Despite the recent increase of measures developed to assess the cognitive symptoms of social anxiety disorder (SOC), their validation is still largely preliminary. Thus, the present studies sought to replicate and extend the psychometric evaluation of the Social Thoughts and Beliefs Scale (STABS). Study 1 involved both participants with SOC (n= 206) and healthy controls (n= 222) that completed the STABS and other related measures of anxiety. In Study 2, participants with SOC (n= 66) completed exposure-based psychotherapy for SOC with the STABS used to track symptom changes. Together, the two studies provided additional support for the validity and reliability of the STABS as a measure of the cognitive symptoms of SOC. However, contrary to previous research with two subscales, a single total scale was suggested as the best interpretation of the STABS, as well as the possible general presentation of the cognitive symptoms of SOC.
