PhD, Ekechukwu, R.O. PhD Abstract: The study investigated the Psycho-Biological predictors of suicide behaviour among undergraduate students of University of Port Harcourt, Nigeria. Three research questions and three hypotheses guided the study. The study adopted the correlational research design, with a sample of 600 students. Multistage sampling technique was employed in drawing the sample. The instrument for collection of data for this study was a questionnaire named "Suicide Behaviour Scale (PSBS). It is divided into two sections: A and B. Section A was designed to elicit information on the respondent's demographic profile (gender). Section B further contains items on psycho-biological predictors of suicide behaviour. The face, content and construct validities of the instrument were statistically ensured. Simple regression was used to analyze data generated. Result indicated that emotion dysregulation and self-esteem are significant predictors of suicide behaviour among students in University of Port Harcourt, Rivers State, but genetic disposition is not a significant predictor of suicide behaviour. Based on the findings, it was recommended among others that tertiary institutions should establish counselling unit that is fully functional and with qualified counsellors; and lecturers and the school authorities should make it a point of duty to sensitize and encourage students to visit the counselling units from time to time in order to get guidance on how to cope with challenges of life.
