目的:评价抑郁症行为激活量表中文版(the Chinese version of behavioral activation for depression scale，C-BADS)应用于美沙酮维持治疗(methadone maintenance treatment，MMT)患者的信度和效度。方法:在武汉市MMT门诊随机招募162例阿片类物质成瘾患者接受C-BADS量表调查，采用SPSS 21.0软件进行项目分析和探索性因子分析( exploratory factors analysis，EFA)，AMOS 24.0软件进行验证性因子分析(confirmatory factor analysis，CFA)。结果:各维度与总分之间的相关系数为0.228～0.813(均 P<0.01)，除激活维度外，其余各维度间的相关系数均低于各维度与总分之间的相关系数。各条目与总分之间的相关系数为0.060～0.716。探索性因子分析提取了4个公因子，分别命名为回避/沉思(avoidance/rumination，AR)、激活(activation，AC)、社会功能减退(social impairment，SI)和工作/学习功能减退(work/school impairment，WS)，对总方差的累积贡献率为51.153%，各条目在所属因子上的因子负荷为0.328～0.797。验证性因子分析模型的整体拟合度指标为：χ 2/ df＝1.594，CFI＝0.839，TLI＝0.820，IFI＝0.844，RMSEA＝0.069，SRMR＝0.089。量表内部一致性信度Cronbach's α系数为0.790，分半信度为0.827。 结论:C-BADS用于测量MMT患者行为激活状况具有较好的内部一致性信度和结构效度，但仍需要进一步修改。

Objective:To evaluate the reliability and validity of the Reward Probability Index-Chinese version (C-RPI) among individuals with opioid dependence.Methods:A total of 160 individuals with opioid dependence were recruited from the methadone maintenance treatment(MMT) programs in Wuhan.The C-RPI was used in the investigation, and items/exploratory factors and confirmatory factors were adopted to analyze with IBM SPSS 22.0 and AMOS 24.0, respectively.Results:The correlation between each item and the total score of the scale was 0.325-0.657 (all P<0.01) and the item discrimination of the scale was good.Exploratory factor analysis extracted two factors, including reward probability and environmental suppressors, and a load of each item on its factor ranged from 0.519 to 0.744.The fitting indexes of confirmatory factor analysis were as follows: χ 2/ df=1.623, RMR=0.030, RMSEA=0.063, IFI=0.902, TLI=0.885, CFI =0.900.The internal consistency coefficient (Cronbach's α) of the C-RPI was 0.800; and there was no ceiling/floor effect on each dimension and total scale. Conclusion:The classification of dimensions for the C-RPI is reasonable, and the scale has good reliability and validity to measure the ability to obtain environmental rewards for individuals with opioid dependence.
