A number of factors can predict or increase the risk of suicide among those who have mental illnesses. Aim: This study aimed to look at the factors influencing suicide behavior among mentally ill patients at the University of Port Harcourt Teaching Hospital. Materials and Methods: This was a cross-sectional study conducted among attendees of Neuropsychiatric Outpatient Clinic of the University of Port Harcourt Teaching Hospital. A structured questionnaire covering socio-demographic characteristics and other factors were self-administered to 75 patients diagnosed with various psychiatric disorders by consultants Psychiatrists and attending the out-patient clinic via a systematic random sampling. Ethical approval was obtained from the ethical committee of the University of Port Harcourt Teaching Hospital and all other ethical provisions were followed. Descriptive and inferential statistics were used to analyze the data. p value ≤ 0.05 was considered statistically significant. Results: Majority of the respondents were male (81%), single (76.0%), unemployed (36.0%), low income earners (73.4%) and between the ages of 21 and 30 (44%). Majority had tertiary education (58.7%) followed by respondents with secondary education (33.3%).
