Note. CFI = comparative fit index; df = degrees of freedom; IFI = incremental fit index; NFI = normed fit index; NNFI = non-normed fit index; RMSEA = root-mean-square error of approximation; SRMR = standardized root-mean-square residual; DS-II: Demoralization Scale-Second Version; PHQ: Patient Health Questionnaire
^aAs a Original 2-dimensional model and 16 items
^b16 items of DS-II was evaluated as a one-dimensional model
^cTwo dimensional model including 16 items of DS-II as one factor, and 9 items of PHQ as another factor
