Objectives:
The aim of the study was to develop a Polish adaptation of the Suicide Behaviors Questionnaire-Revised (SBQ-R) by A. Osman et al. The questionnaire is a self-descriptive measure of suicidal tendencies (suicidal behaviors, including ideation and attempts) composed of four questions.

Methods:
A total of 926 university and post-graduate students from Lodz (526 women and 400 men) were included in the adaptation study. In addition, the Beck’s Depression Inventory, the Psychological Pain Scale by Holden et al. and the Purpose in Life (PIL) test by Crumbaugh and Maholick were used to evaluate the construct validity of the SBQ-R.

Results:
The exploratory and confirmatory factor analysis supported an assumed onedimensional structure of the questionnaire, with satisfactory internal consistency, evaluated by Cronbach’s alpha, equal to 0.83. The significant positive correlations were observed between the questionnaire scores and level of depression and psychological pain, while a negative correlation between the questionnaire scores and purpose in life. Participants who had previously demonstrated suicidal behavior, those who reported suicidal thoughts and those from a family with a history of suicide attempts or alcohol addiction obtained a significantly higher score in the SBQ-R.

Conclusions:
The findings indicate that the Polish adaptation of the SBQ-R by Osman et al. has good psychometric characteristics and can be considered in both research and clinical practice.
