Translation, cross-cultural adaptation, and psychometric investigation of Chinese version of the Orbach & Mikulincer Mental Pain Scale in patients with depressive disorder.

Purpose: This study aimed to translate, cross-culturally adapt, and preliminarily test the psychometric properties of the Chinese version of the Orbach & Mikulincer Mental Pain Scale (OMMP).

Methods: Psychometric investigation was performed on 240 depressed patients. The reliability of the Chinese version of the OMMP scale was expressed by internal consistency reliability and test-retest reliability (2-week interval), and confirmatory factor analysis (CFA) on the 8-factor, 31-item OMMP was conducted to examine the construct validity.

Results: The CFA showed that the modified model with 31 items had good reliability (Cronbach's α range = 0.691-0.871; ICC = 0.818). Criterion-related validity was also supported by significant and positive correlations between the eight factors and worst-ever suicidal ideation as well as depressive symptoms.

Conclusion: The results indicated the usefulness of the OMMP-31 for Chinese depressed patients. It is necessary to estimate psychological pain to improve suicide management in the clinical setting.
