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.
社交焦虑相关信念量表（SBSA）评估的是适应不良的社会评价信念，这是社交焦虑障碍（SAD）模型中的一个关键方面，在研究和临床环境中经常被测量。SBSA 在学生样本中进行了心理测量学评估，但在 SAD 诊断的大量个体样本中没有进行评估。本研究在来自多项研究的 SAD 个体样本中测试了 SBSA 的心理测量特性（总 N = 284）。结果表明，SBSA 的最佳因子结构是相关的三因子模型（高标准信念因子、条件信念因子、无条件信念因子）。SBSA 总分及其分量表（基于因子组成）表现出良好的内部一致性。在结构有效性方面，SBSA 总分、高标准信念分量表和条件信念分量表与社交焦虑的测量指标相关性更强，而与抑郁的测量指标相关性较弱，尽管无条件信念分量表与社交焦虑和抑郁的测量指标都有相似的相关性。在判别有效性方面，SAD 个体样本的 SBSA 总分和分量表得分高于无 SAD 个体样本（N = 32）。这些发现为 SBSA 用于评估适应不良的社会评价信念提供了心理测量学依据。
