To facilitate life span research on depressive symptomatology, a depressive symptom scale for the California Psychological Inventory (CPI) is needed. The authors constructed such a scale (the CPI-D) and compared its psychometric properties with 2 widely used self-report depression scales: the Beck Depression Inventory and the Center for Epidemiological Studies Depression Scale. Construct validity of the CPI-D was examined in 3 studies. Study 1 established content validity, classifying CPI-D items into Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition depressive symptoms. Study 2 used 3 large samples to gather evidence for reliability and validity: correlational analyses demonstrated alpha reliability and convergent and discriminant validity; factor analysis provided evidence for discriminant validity with anxiety; and regression analyses demonstrated comparative validity with existing standard PI scales. Study 3 used clinician ratings of depression and anxiety as criteria for external validity.
为推动对抑郁症状的寿命研究，需要一个用于加利福尼亚心理调查表（CPI）的抑郁症状量表。作者构建了这样一个量表（CPI-D），并将其心理测量特性与2个广泛使用的自我报告抑郁量表进行了比较：贝克抑郁量表和流行病学研究中心抑郁量表。在3项研究中检验了CPI-D的结构效度。研究1确立了内容效度，将CPI-D项目分类为《精神疾病诊断与统计手册（第四版）》中的抑郁症状。研究2使用3个大样本收集可靠性和效度证据：相关分析证明了α信度以及聚合效度和区分效度；因素分析为与焦虑的区分效度提供了证据；回归分析证明了与现有标准CPI量表相比的效度。研究3使用临床医生对抑郁和焦虑的评定作为外部效度的标准。
