Objective: Suicidal behavior is serious public health problem. Interpersonal Psychological Theory of Suicide-IPT tells that feelings of thwarted belongingness and perceived burden someness are composed of two perceptions that make people tend to suicide. But the theory argues that will is not sufficient for occurrence of a suicidal behaviour. Individual must have acquired capability for suicide as well. Recently it is seen that IPT is a theorethical framework that is frequently used in suicide researches. The purpose of this study was to investigate the psychometric properties of the Turkish versions of the Interpersonal Needs Questionnaire (INQ) and Acquired Capability for Suicide Scale- Fearlessness about Death (ACSS-FAD). Method: Data were collected from 409 university students. Results: The Turkish Interpersonal Needs Questionnaire and the Acquired Capability for Suicide- Fearlessness about Death scale demonstrated adequate psychometric properties. Both had high internal consistency and test-retest reliabilities. Discussion: The results of the present study have revealed that the Turkish versions of the Interpersonal Needs Questionnaire (INQ) and Acquired Capability for Suicide Scale-Fearlessness about Death (ACSS-FAD) are reliable and valid instruments for measuring the constructs of the Interpersonal Psychological Theory of suicide. Therefore, we conclude that the two measuring instruments may contribute to the suicidological research and clinical practice in Turkey.

Joiner, TE; Gençöz, Faruk; Gençöz, Tülin; Metalsky, GI; Rudd, MD (2001-06-01)
It is well known that depressive symptoms represent a risk for suicidality in general. It is less clear, however, that general depressive symptoms comprise a definite suicide risk factor for people with schizophrenia. Based on this, as well as on the early writings of E. Bleuler (1911/1987), it was hypothesized that there may be a particular aspect of depressive symptoms that combines with schizophrenia to encourage suicidality. Specifically, schizophrenia may impart to self-concept a quality of self-hatred...
