Methods: The individuals participating in the study were recruited from outpatient units of a medical center and a municipal hospital in northern Taiwan. The study sample (n = 2009) included 237 patients with depressive disorders, 160 with schizophrenia, and 1612 with HIV/AIDS. The reliability and construct validity of the MS-C was evaluated by confirmatory factor analysis (CFA) and Rasch analysis. Results: The results of the CFA showed that the MS-C has adequate construct validity with all indices meeting the criteria, except for chi-square values. The Rasch analysis supported the four-point rating scale structure and a unidimensional construct of the MS-C. The DIF analysis showed that all items demonstrated stable measurement properties among the different diagnosis groups (major depression, schizophrenia, HIV/AIDS). Conclusion: This study found that MS-C has acceptable psychometric qualities in terms of reliability, construct validity, rating scale performance, and item characteristics when applied to patients with depression, schizophrenia, and HIV/AIDS in Taiwan. ? 2013 Informa Healthcare.[SDGs]SDG3acquired immune deficiency syndrome; adolescent; adult; aged; article; control; factorial analysis; female; human; major depression; male; middle aged; psychological aspect; psychological rating scale; psychology; psychometry; reproducibility; Taiwan; very elderly; young adult; Acquired Immunodeficiency Syndrome; Adolescent; Adult; Aged; Aged, 80 and over; Depressive Disorder, Major; Factor Analysis, Statistical; Female; Humans; Internal-External Control; Male; Middle Aged; Psychiatric Status Rating Scales; Psychometrics; Reproducibility of Results; Schizophrenic Psychology; Taiwan; Young Adultjournal article10.3109/11038128.2013.838999240668562-s2.0-84886802606
