Do Gender and Relationship Length Jointly Moderate the Effects of Marital Dysfunctional Beliefs and Expectations on Marital Commitment Among Rwandan Married Couples?

Abstract

This study investigates how gender and relationship length independently and jointly influence the effects of marital expectations and dysfunctional beliefs on marital commitment. Using a cross-sectional design, data were collected from 426 married individuals through standardized measures of dysfunctional beliefs, marital expectations, and commitment. Moderation analysis was performed using Process Macro for SPSS. Results revealed that unmet expectations and dysfunctional beliefs were linked to reduced commitment, with men showing a greater decline than women in these conditions. Longer relationships were also associated with a greater decline in commitment. However, no significant interaction between gender and relationship length was found. The findings underscore the critical roles of gender and relationship duration in marital commitment, suggesting gender-specific interventions, particularly for men, and the importance of addressing unrealistic expectations and beliefs early in the relationship to maintain commitment over time.
