渥太华自伤功能量表在青少年情感障碍患者中的信效度检验

Reliability and validity of Ottawa Self-Injury Inventory-Functions in adolescent patients with affective disorder

目的 对渥太华自我伤害功能量表(Ottawa Self-Injury Inventory-Functions,OSI-F)的信效度进行检验。方法 纳入昆明医科大学第一附属医院精神科明确诊断为情感障碍的青少年患者228例,指导完成渥太华自伤功能量表。结果 探索性因子分析显示KMO值为0.811,OSI-F共提取4个维度,各维度累积方差贡献率为60.793%,总条目Cronbach’sα系数为0.845,各维度Cronbach’sα系数为0.731-0.910,组合信度为0.73-0.92,各维度与总量表之间的相关系数为0.597-0.721。验证性因子分析显示,最终拟合优度的卡方检验与自由度的比值(χ^(2)/df)=1.832,近似误差均方根(RMSEA)=0.061,拟合优度指数(GFI)=0.879,比较拟合指数(CFI)=0.935增值适配指数(IFI)=0.978,非规准适配指数(TLI)=0.934。结论 渥太华自我伤害功能调查表在青少年情感障碍患者中具有良好的效度和信度,可作为青少年情感障碍患者评估自伤功能的有效工具。

Objective This study aimed to test the reliability and validity of Ottawa Self-Injury Inventory-Functions(OSI-F).Methods The demographic information and the OSI-F were assessed among 228 adolescent patients with affective disorder.Results The KMO value was O.811,and EFA analysis suggested that OSI-F indicated four factors,including emotion regulation,stimulation seeking,interpersonal influence and interpersonal boundaries.The above four factors explained 60.793%of the total variances.The internal consistency Cronbach'sαcoefficient was 0.845 for OSI-F,0.731 for interpersonal boundaries,0.846 for emotion regulation,0.889 forinterpersonal influence,and 0.910 for stimulation seeking The correlation coefficient between each dimension and the total table is 0.597-0.721.The confirmatory factor analysis fiting indexes:χ^(2)/df was 1.832,root mean square error of approximation(RMSEA)was 0.061,goodness of fit index(GFI)was 0.879,comparative fit index(CFI)was 0.935,iciemental fit index(IFI)was(IFI)=0.978 and Tucker-Lewis index(TLI)was 0.934.Conclusion The Ottawa Self-Injury Inventory-Functions shows sufficient validity and reliability which can be used to evaluate self-injury function in adolescent patients with emotional disorders.
