Depression has major negative consequences for individuals and society, and psychological assessment tools for early disease detection are needed. The aim of this study was to investigate the reliability and validity of an updated Japanese version of the Children's Depression Inventory (CDI-J) and set a cut-off score for the detection of depression.
The participants consisted of 465 children and adolescents aged 7-17 years. The control (CON) groups consisted of students recruited from elementary and junior-high school (CONEJ) and children recruited from among hospital staff members (CONRE), while the outpatient clinical (OPC) groups consisted of pediatric psychosomatic outpatients (OPCPD) and adolescent psychiatric outpatients (OPCPS). The CON and OPC CDI-J scores underwent factor analysis using varimax rotation, followed by measurement invariance analysis. The Youth Self-Report (YSR) was administered to assess concurrent validity. The Mini-International Neuropsychiatric Interview was administered to the OPC group to diagnose current depressive symptoms. Receiver operating characteristics (ROC) analysis was conducted to evaluate case-finding performance and to set cut-off points for the detection of depression.
The CDI-J was reliable in terms of internal consistency (Cronbach α = 0.86; mean inter-item correlation, 0.16). Re-test reliability was substantial (mean interval 18 days: γ = 0.59, P < 0.05). The four-factor solution exhibited adequate internal consistency (range, 0.52-0.73) and correspondence (Pearson correlation of 0.65 with the YSR) for both the CON and OPC groups. On ROC analysis the optimal cut-off score was 23/24.
The CDI-J can be used as a reliable and well-validated instrument alongside standard diagnostic procedures.
抑郁症对个人和社会都有重大负面影响，因此需要用于早期疾病检测的心理评估工具。本研究旨在调查更新后的日语版儿童抑郁量表（CDI-J）的信度和效度，并设定抑郁症检测的临界分数。
参与者包括465名7至17岁的儿童和青少年。对照组（CON）由从小学和初中招募的学生（CONEJ）以及从医院工作人员中招募的儿童（CONRE）组成，而门诊临床（OPC）组由儿科身心门诊患者（OPCPD）和青少年精神科门诊患者（OPCPS）组成。对CON组和OPC组的CDI-J分数进行了使用方差最大化旋转的因子分析，随后进行测量不变性分析。采用青少年自我报告（YSR）来评估同时效度。对OPC组进行了迷你国际神经精神病学访谈以诊断当前的抑郁症状。进行了受试者工作特征（ROC）分析以评估病例发现性能并设定抑郁症检测的临界点。
CDI-J在内部一致性方面是可靠的（克朗巴哈α系数=0.86；平均项目间相关性为0.16）。重测信度较高（平均间隔18天：γ=0.59，P<0.05）。四因素解决方案在CON组和OPC组中均表现出足够的内部一致性（范围为0.52 - 0.73）和对应性（与YSR的皮尔逊相关系数为0.65）。在ROC分析中，最佳临界分数为23/24。
CDI-J可作为一种可靠且经过充分验证的工具与标准诊断程序一起使用。
