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.
