Reliability and validity of Mee-Bunney Psychological Pain Assessment Scale Turkish version

In this study, we aimed to investigate the validity and reliability of the Turkish version of the Mee Bunney Psychological Pain Assessment Scale (MBPPAS), which questions the frequency, intensity and acute period of psychological pain. We also aimed to investigate whether psychological pain allows measuring acute suicidal behavior; and whether there were different levels of psychological pain in suicide-related disorders. The study included 73 patients with major depressive disorder, 50 patients with bipolar disorder and 77 healthy controls. MBPPAS, Beck Depression Inventory, Beck Scale for Suicidal Ideation, Beck Hopelessness Scale, Physical Pain Scale, and Psychache Scale were filled by the participants. In the internal consistency, the Cronbach’s alpha coefficient was found to be 0.95 and the item-total score correlation coefficients were between 0.51 and 0.89. Explanatory factor analysis showed that the scale was loaded under the single factor, which had an eigenvalue of 7.02, explaining 70.23% of the total variance. Factor loads of the items were found between 0.57 and 0.92. Discriminant function analysis showed that the scale classified the patient group and the healthy group, also the patients with and without suicide attempt, and each group was classified as successfully when the three groups were considered together. Besides the fact that the Turkish version of the scale is valid and reliable, it has been shown that it can be useful (partially) in the studies conducted with patients in the acute phase and in distinguishing disorders from each other in suicide-related entities such as mood disorders.
