Application of Chinese version of behavioral activation for depression scale in patients in methadone maintenance treatment / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To evaluate the reliability and validity of the Chinese version of behavioral activation for depression scale (C-BADS) in patients in methadone maintenance treatment (MMT).Methods:A total of 162 opioid addicts were recruited from the MMT programs in Wuhan city for the C-BADS investigation.Items analysis and exploratory factors analysis (EFA) were conducted with SPSS 21.0 and confirmatory factors analysis (CFA) was conducted with AMOS 24.0.Results:The correlation coefficients between subscales and total score were 0.228-0.813 (all P<0.01). Except for activation subscale, the correlation coefficients among subscales were lower than those between subscale dimensions and total score.The item-total score correlations coefficient were 0.060-0.716.Four factors were extracted by EFA, named avoidance/rumination(AR), activation(AC), social impairment(SI) and work/school impairment(WS) respectively, which the cumulative variance was 51.153%, and the factor loading of each item ranged from 0.328 to 0.797.The fitting indexes of CFA model were as following χ 2/ df=1.594, CFI=0.839, TLI=0.820, IFI=0.844, RMSEA=0.069, SRMR=0.089.The Cronbach's α of the scale was 0.790, and the split-half reliability coefficient was 0.827. Conclusion:C-BADS has good internal consistency reliability and construct validity, but it still needs to be modified for the measurement of behavior activation of patients in MMT.
