This study examined the extent which sense of purpose, coping styles and perceived societal attitudes predict mental wellbeing of retirees in Akwa Ibom State, Nigeria. The objectives of the study were to predict how sense of purpose, coping styles and perceived societal attitude predicts the mental well-being of retirees in Akwa Ibom State. Three research questions and three null hypotheses were raised and formulated respectively for the study. The ex-post facto survey design was used for the study. The population of the study consisted of 28,898 state government retirees in Akwa Ibom State as at April 2025. A sample size of 709 retirees was used for the study. Multi-stage sampling procedure involving random sampling and purposive sampling techniques were adopted for the study. Data were collected using a researcher developed instrument named, "Personal-Social Variables and Retirees' Mental Wellbeing Questionnaire" (PSVRMWQ). The instrument was subjected to face validity by three experts. The reliability of the PSVRMWQ was .90, determined using Cronbach's Alpha Statistics. Data were analysed using mean, standard deviation, independent t-test and simple linear regression. The null hypotheses were tested at 0.05 level of significance. The finding revealed that sense of purpose, coping and perceived societal attitude is a significant independent predictor of mental wellbeing. It was concluded based on the findings that the mental wellbeing of retirees in Akwa Ibom State is significantly influenced by their sense of ongoing purpose, their ability to employ effective coping strategies, and their perception of being valued by society. It was recommended among others that Counsellors should develop and facilitate purpose-enhancement and mental health workshops for pre-retirees and retirees.
