Marital conflict resolution through schema therapy and mutual behaviour analysis for enhanced self-differentiation in Kwara State

Introduction Marital conflict remains a persistent challenge among couples in Nigeria, often driven by deep-rooted maladaptive cognitive schemas, dysfunctional behavioural patterns, and poor self-differentiation. This study examined marital conflict resolution through Schema Therapy and Mutual Behaviour Analysis for enhanced self-differentiation among married couples in Ilorin Metropolis, Kwara State. Methods A quasi-experimental pretest–posttest control group design was adopted, involving 45 married couples. The instruments used were the Maladaptive Schema and Behavioural Patterns in Marital Conflict Scale (MSBPMC) and the Self-Differentiation Questionnaire (SDQ). Data were analyzed using mean, standard deviation, and ANCOVA at 0.05 level of significance. Results Findings revealed that emotional deprivation, abandonment/insecurity, and unrelenting standards were the most dominant maladaptive schemas, while demand–withdraw, emotional withdrawal, and avoidance behaviours were most prevalent. Couples also exhibited low self-differentiation characterized by emotional reactivity and dependence. Both Schema Therapy and Mutual Behaviour Analysis significantly reduced marital conflict and improved self-differentiation, with Schema Therapy showing a slightly greater effect. The combined ST+MBA model was most effective. Discussion and recommendations The study concludes that integrative therapeutic approaches are essential for effective marital conflict resolution.
