Özet:The purpose of the present study was to explore the frequency, characteristics and functions of non-suicidal self-injury (NSSI), and to identify psychological and psychophysiological factors that distinguish self-injurers from non-injurers, in a sample of Turkish college students. In Study 1, frequency and characteristic features of self-injury were explored, and potential gender differences in NSSI were assessed. Next, self-injurers and non-injurers were compared on emotion dysregulation, self-compassion, self-criticism, positive and negative affect, and thought suppression variables. In Study 2, in a laboratory-based design, pain perception and changes in pain perception as a result of distress were explored. Furthermore, skin conductance levels were recorded to assess physiological reactivity of participants during painful and distressing stimuli. Findings suggested that NSSI is a frequent and repetitive behavior in the current sample, which commonly serves an emotion regulation function. The only gender difference was found in the methods of self-injury. As expected, NSSI group scored higher on emotion dysregulation, self-criticism, negative affect, and thought suppression; and lower on self-compassion as compared to non-injurers. Furthermore, self-injurers had higher tolerance to pain; however, pain perception did not change as a function of distress. Although self-injurers reported relatively more distress during a distressing task, both groups showed comparable levels of physiological reactivity and distress tolerance in objective measures. Moreover, self-injurers and controls did not differ in physiological reactivity during painful stimuli. Importance, limitations, and possible implications of the present study, as well as recommendations for future research were discussed.
