Objective: Suicidal rates are increasing rather than decreasing. In the case of suicide, the evaluations of individuals at the time of consult are vital for both the patient and the clinician. In this study, it was aimed to investigate the validity and reliability of the Turkish version of the Psychache Scale used in the evaluation of suicidal behavior and/or suspected individuals. Methods: The study was carried out with 106 inpatients and outpatients with major depressive disorder who were treated in Cukurova University School of Medicine Department of Psychiatry and 94 healthy controls. In addition to Turkish version of the Psychache Scale, Beck Depression Inventory, Beck Hopeless-ness Scale, Beck Suicidal Ideation Scale, and Visual Analogue Scale were administered to the patient and control groups. The scales were filled in by the participants. Results: Cronbach alpha coefficient was 0.98 in the internal consistency and item-total score correlation coefficients were between 0.80-0.92. In the exploratory factor analysis, a one-factor solution was obtained and the eigenvalue was 10.09, explaining 77.60% of the total variance. The factor loadings of the Psychache Scale items ranged from 0.73 to 0.93. According the discriminant function analysis, it was determined that the patient group and the healthy group, suicide attempted and non-attempted patient [Anadolu Psikiyatri Derg 2018; 19(0.100): 14-20]
