This study examined the factor structure of the Children's Depression Inventory (CDI) among children and adolescents with chronic pain using exploratory and confirmatory factor analysis in a large, multisite sample of treatment-seeking youth. Participants included 1,043 children and adolescents (ages 8-18) with a range of chronic pain complaints who presented for initial evaluation at 1 of 3 tertiary care pediatric chronic pain clinics across the United States. They completed the CDI and reported on pain intensity and functional disability. Factor analysis was conducted using a 2-step (exploratory and confirmatory) approach. Results supported a 5-factor model for the CDI with good fit to the data. The distribution and item-total correlations of the somatic items (eg, pain complaints, fatigue) were explored in this sample. Results indicate that the CDI is a useful tool for assessing depressive symptoms in youth with chronic pain, but some caution is warranted in interpreting the clinical significance of scores in light of the overlap of specific symptoms common to both pain and depression.
The CDI can be considered a valid tool for assessing mood symptoms in children with chronic pain. Caution is encouraged when interpreting the clinical significance of scores due to symptom overlap between chronic pain and depression.
本研究采用探索性和验证性因子分析，在一个大型、多地点的寻求治疗的青少年样本中，研究了儿童抑郁量表（CDI）在慢性疼痛儿童和青少年中的因子结构。参与者包括 1043 名患有各种慢性疼痛的 8-18 岁儿童和青少年，他们在美国 3 个三级儿童慢性疼痛诊所中的 1 个进行了初始评估。他们完成了 CDI，并报告了疼痛强度和功能障碍。使用 2 步（探索性和验证性）方法进行因子分析。结果支持 CDI 的 5 因素模型，数据拟合良好。在这个样本中，探讨了躯体症状（如疼痛主诉、疲劳）的分布和项目总分相关性。结果表明，CDI 是评估慢性疼痛青少年抑郁症状的有用工具，但鉴于疼痛和抑郁共有的特定症状重叠，在解释分数的临床意义时需要谨慎。
CDI 可被视为评估慢性疼痛儿童情绪症状的有效工具。由于慢性疼痛和抑郁之间存在症状重叠，因此在解释分数的临床意义时应谨慎。
