Data-model fit indices and model comparisons for Internalized Stigma of Mental Illness (ISMI) and its five subscales (n = 162).

df = degree of freedom; CFI = comparative fit index; RMSEA = root mean square of approximation; SRMR = standardized root mean square residual. M1: Configural model; M2: All factor loadings were invariant between test and retest; M3: All factor loadings and item intercepts were invariant between test and retest; M4: All factor loadings, item intercepts, and construct means were invariant between test and retest. aInternalized Stigma of Mental Illness: using the sum scores of the five subscales as observed item scores. *p<0.05.
