Psychometric Evaluation of the Thai Male Depression Risk Scale (MDRS-TH)

Previous studies have reported that males frequently suffer from major depression. However, due to the norms of masculine roles, in which emphasis is placed in displaying strength, invulnerability, and control, the ways that some men exhibit depression may differ from traditional diagnostic symptoms of major depressive disorder. To this end, the Male Depression Risk Scale (MDRS) has been developed in order to better identify those men, who experience low moods and are at risk for suicide. This study evaluated the psychometric properties of the Thai version of the MDRS (MDRS-TH). A cross-sectional study was conducted with 600 participants, who were recruited through social media (male N=300). The average age was 38.74 years. About half of the participants were married (51.5%). The majority identified themselves as Buddhist (94.66%) and had completed postgraduate education (31.16%). The samples had a variety of occupations, including farmer, employee, student, retired, own business, etc. The data were analyzed using confirmatory factor analysis, Cronbach's alpha coefficient, and criterion-related validity using Pearson's correlation. The overall analysis (N=600) found that the MDRS-TH was consistent with the empirical data (CFI=0.918, TLI=0.905, SRMR=0.05, and RMSEA=0.05). The final model consisted of 5 components: 1) emotional suppression, 2) alcohol use, 3) anger & aggression, 4) somatic symptoms, and 5) risk-taking behaviors. The internal consistency of the MDRS-TH total score was 0.89, and the correlation criterion-related validity with the PHQ-9 was r=0.77. The results supported the fact that the MDRS-TH is a useful screening tool. Utilizing the MDRS-TH in primary care settings may assist to identify those men who are at risk for male-specific symptoms of depression so that early identification and intervention can be facilitated. In future studies, the generalizability of the scale would be strengthened if efforts to improve cross-cultural validation involving different cultural groups in Thailand were prioritized.
