Marital Satisfaction and Psychological Well-Being Among Married Adults in Ibadan, Oyo State, South West Nigeria

Marital satisfaction is a fundamental predictor of psychological well-being in adulthood, and its determinants in the Nigerian cultural context, where marital expectations are shaped by both traditional and modern norms, merit empirical investigation. This study examines the relationship between marital satisfaction and psychological well-being among married adults in Ibadan, Oyo State. A cross-sectional survey is applied to 240 married adults aged 25 to 60 years recruited through purposive sampling from two residential communities and one market association. The Couple Satisfaction Index and Ryff's Scales of Psychological Well-Being are administered alongside a questionnaire capturing marriage duration, number of children, household income, and marital conflict frequency. Pearson correlation, t-test, and multiple regression are computed in SPSS. Literature from South West Nigerian adult populations identifies communication quality, financial stability, and extended family interference as the three strongest predictors of marital satisfaction, with marital satisfaction in turn predicting higher positive affect and sense of purpose. Sternberg's Triangular Theory of Love and Ryff's Multidimensional Model of Well-Being provide the theoretical underpinning. Findings are expected to show a significant positive relationship between marital satisfaction and overall well-being, with communication quality as the strongest predictor across gender groups. Results will support couple counselling practice in Ibadan mental health services. Keywords: marital satisfaction, psychological well-being, married adults, Ibadan, South West Nigeria.
