The Relationship between Extra-dyadic Stress, Intra-dyadic Stress and Marital Satisfaction in Couples of the Greater Area of Beirut (SBS thesis, Haigazian University)https://doi.org/10.62811/th.0209https://haigrepository.haigazian.edu.lb/handle/123456789/256This study investigated the impact of extra-dyadic stress on marital satisfaction with intra-dyadic stress mediating this relationship in Lebanese couples of the Greater Area of Beirut. A total of 150 couples (300) individuals participated in the study by filling out a demographic questionnaire, Multidimensional Stress Questionnaire for couples MSD-Q (external stress, Multidimensional Stress Questionnaire for couples MSD-Q (internal stress), and Relationship Assessment Scale (RAS). Correlation and regression analyses were used to examine the relationship between the different variables. The results showed that a significant negative relationship exists between extra-dyadic stress and marital satisfaction, positive significant relationship between extra-dyadic stress and intra-dyadic stress, and negative significant relationship between intra-dyadic stress and marital satisfaction in Lebanese couples. The relationship between extra dyadic stress and marital satisfaction was mediated by intra-dyadic stress which was reflected by the multi-linear regression analysis that showed a diminished effect of extra-dyadic stress on marital satisfaction when intra-dyadic stress was entered into the equation. The posited hypotheses were verified. We concluded that Lebanese couples’ experience of extra-dyadic stress indeed spills over into the relationship by increasing intra-dyadic stress which in turn lowers their marital satisfaction.
