The Work and Social Adjustment Scale (WSAS) is a brief global measure of functional impairment that is widely used in adult health. We have adapted the WSAS for its use in youth, the WSAS-Youth version (WSAS-Y) and WSAS-Parent version (WSAS-P). This study evaluated the psychometric properties of the scale. The internal consistency, factor structure, convergent and divergent validity, test-retest reliability and sensitivity to change of the WSAS-Y/P were studied in 525 children and adolescents with obsessive-compulsive disorder and related disorders receiving treatment. The internal consistency of the WSAS-Y/P was excellent across diagnostic groups and time-points. Exploratory factor analysis extracted a single-factor of functional impairment, explaining in excess of 85% of the variance. The test-retest reliability was adequate. The WSAS-Y/P correlated more strongly with other measures of functional impairment than with measures of symptom severity, indicating good convergent/divergent validity. Finally, the WSAS-Y/P was highly sensitive to change after treatment.
工作和社会适应量表（WSAS）是一种广泛用于成人健康的简短的全球功能障碍评估方法。我们已经对其进行了改编，以便在青少年中使用，即 WSAS-青少年版（WSAS-Y）和 WSAS-家长版（WSAS-P）。本研究评估了该量表的心理测量特性。在接受治疗的 525 名患有强迫症和相关障碍的儿童和青少年中，研究了 WSAS-Y/P 的内部一致性、因子结构、聚合和发散效度、重测信度以及对变化的敏感性。WSAS-Y/P 在各个诊断组和时间点的内部一致性都非常好。探索性因子分析提取了一个功能障碍的单一因子，解释了超过 85%的方差。重测信度是足够的。WSAS-Y/P 与其他功能障碍评估指标的相关性强于与症状严重程度评估指标的相关性，表明良好的聚合/发散效度。最后，WSAS-Y/P 在治疗后对变化非常敏感。
