Objective: Investigate the psychometric properties of the Thai version of the 30-item Mental Health Recovery Measure (Thai-MHRM) for person with major depressive disorder (PMDD).

Materials and Methods: An instrument modification and psychometric properties testing were employed to explore the qualification of the recovery instrument among PMDD in Thailand. Three hundred eight Thais adult with MDD who have experienced the mental health services in the mental health and psychiatric department of the hospital or community health centers were recruited for this study. A confirmation factor analysis (CFA) was used to examine the factor structure of the Thai-MHRM. Data were analyzed using descriptive statistics and a linear structural relationship (LISREL, version 8.72) analysis. The Cronbach’s alpha was applied to assess the internal reliability of the Thai-MHRM.

Results: CFA of the Thai-MHRM produced eight factors that was replicated using confirmatory techniques. Each factor had satisfactory internal reliability (Cronbach’s alpha range 0.68 to 0.86). The Thai-MHRM average total scores for the participants was 80 (SD 20). The internal reliability (coefficient alpha) of the Thai-MHRM total score was 0.93. The one-week test-retest reliability was 0.92. The Thai-MHRM instruments demonstrated excellent internal consistency.

Conclusion: The present study provides initial support for use of the Thai-MHRM-30 as a valid and reliable assessment of perceived recovery among PMDD and may be applied in routine care. To facilitate recovery as a nursing outcome, evaluation of the intervention and search for recovery instrument need to be integrated into the nursing practice.
