Abstract

The Self-Beliefs related to Social Anxiety (SBSA) scale assesses maladaptive social-evaluative beliefs, a key aspect in models of social anxiety disorder (SAD) that is frequently measured in research and clinical contexts. The SBSA has been evaluated psychometrically in student samples, but not in a large sample of individuals diagnosed with SAD. The current study tested the psychometric properties of the SBSA in a sample of individuals with SAD pooled from several studies (total N = 284). Results showed that the optimal factor structure for the SBSA was a correlated three-factor model (high standard beliefs factor, conditional beliefs factor, unconditional beliefs factor). The SBSA total and its subscales (formed based on the factors) exhibited good internal consistency. In terms of construct validity, the SBSA total, the high standard beliefs subscale, and conditional beliefs subscale had stronger associations with a measure of social anxiety than with a measure of depression, although the unconditional beliefs subscale was similarly related to both measures of social anxiety and depression. In terms of discriminative validity, the sample of individuals with SAD had higher SBSA total and subscale scores compared with a sample of individuals without SAD (N = 32). These findings provide a psychometric evidence base justifying the use of the SBSA for the assessment of maladaptive social-evaluative beliefs.
