Validity and Reliability Study of the Turkish Version of the Orbach Mikulincer Mental Pain Scale-8 in a Clinical Population.

ABSTRACT

Purpose: Suicide is a growing public health issue for all societies; identifying suicide risk is crucial. This study aims to evaluate the psychometric properties of the Turkish version of the Orbach and Mikulincer Mental Pain Scale-8 (OMMP-8), which enables the assessment of suicidality in a short time. Patients and Methods: We conducted this study with 148 individuals diagnosed with major depressive disorder and 130 healthy controls. We administered the Hamilton Depression Scale (HDRS), Beck Hopelessness Scale (BHS), Beck Scale for Suicidal Ideation (BSIS), and Mee Bunney Psychological Pain Assessment Scale (MBPPAS) to all participants. Results: Cronbach's alpha values were 0.96, 0.97, and 0.98 for Factors 1, 2, and 3, respectively, and 0.92 for the entire scale. Exploratory (EFA) and confirmatory factor analyses (CFA) proved the 3-factor structure of the scale. The OMMP-8 total score and HDRS (r = 0.851), BSIS (r = 0.836), BHS (r = 0.825), and MBPPAS (r = 0.881) total scores were statistically significantly correlated, indicating convergent and concurrent validity of the scale. The scale successfully discriminated between depression and control groups (89.6%) and participants with and without suicide attempts in the depression group (82.4%). Conclusion: This study demonstrates that the Turkish version of the OMMP-8 scale is valid and reliable for both individuals with depression and healthy controls and can be used in studies investigating suicide risk.
