项目反应理论(IRT)和分类数据因素分析(CDFA)是对旨在测量潜在结构的精神病学测量的心理测量学特性进行分析的补充方法。这些方法被应用于相对较少的儿童和青少年措施。我们提供了第一个IRT和CDFA联合分析的临床测量(短期情绪和感觉问卷-SMFQ)在社区样本的7到11岁的儿童。两个潜在变量模型都支持抑郁症状严重程度的单一潜在连续体的内部结构有效性。SMFQ条目在抑郁潜伏性特征中较严重的一端具有较好的区分性。项目表现不受年龄的影响，尽管年龄与潜在的SMFQ得分显著相关，表明症状严重程度在7-11岁年龄段内增加。这些结果扩展了现有的SMFQ的心理测量学研究，并证实了其标度特性作为社区样本中儿童抑郁症症状严重程度的潜在维度测量。
Item response theory (IRT) and categorical data factor analysis (CDFA) are complementary methods for the analysis of the psychometric properties of psychiatric measures that purport to measure latent constructs. These methods have been applied to relatively few child and adolescent measures. We provide the first combined IRT and CDFA analysis of a clinical measure (the Short Mood and Feelings Questionnaire-SMFQ) in a community sample of 7-through 11-year-old children. Both latent variable models supported the internal construct validity of a single underlying continuum of severity of depressive symptoms. SMFQ items discriminated well at the more severe end of the depressive latent trait. Item performance was not affected by age, although age correlated significantly with latent SMFQ scores suggesting that symptom severity increased within the age period of 7-11. These results extend existing psychometric studies of the SMFQ and confirm its scaling properties as a potential dimensional measure of symptom severity of childhood depression in community samples.
