To examine the psychometric properties of a German adaptation of the Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) in a clinical sample of children (4-12 years) with externalizing behavior disorders.
Data were collected within two clinical trials (N = 264). Factorial validity, reliability, and divergent validity from symptoms of ADHD and oppositional defiant disorder (ODD) were assessed.
Confirmatory factor analyses revealed that a bifactor model consistent with the theoretical assumption of a general construct of impairment (total scale) and additional specific factors (subscales) provided satisfactory data fit. Model-based reliability estimates showed that both the general construct and specific factors accounted for item variance. Internal consistencies were >.70, part-whole corrected item-scale correlations mostly >.30. Correlations between the WFIRS-P Scales and ADHD and ODD symptoms were low to moderate.
The results support the factorial validity, reliability, and divergent validity of the WFIRS-P.
在患有外化行为障碍的4至12岁儿童临床样本中，检验德国版韦斯功能损害评定量表家长报告（WFIRS-P）的心理测量特性。
在两项临床试验（N = 264）中收集数据。评估了与注意缺陷多动障碍（ADHD）和对立违抗性障碍（ODD）症状的因子效度、信度和区分效度。
验证性因子分析表明，一个与损害一般结构（总量表）和额外特定因子（分量表）的理论假设一致的双因子模型提供了令人满意的数据拟合。基于模型的信度估计表明，一般结构和特定因子都解释了项目方差。内部一致性大于0.70，部分-整体校正后的项目-量表相关性大多大于0.30。WFIRS-P量表与ADHD和ODD症状之间的相关性为低到中度。
结果支持WFIRS-P的因子效度、信度和区分效度。
