This study aimed to determine the effectiveness of the Solution-Focused Brief Couple Therapy (SFBCT) on marital satisfaction among married prisoners and their wives. The study design was semiexperimental with a pretest, a posttest, and a control group. Fifty couples (100 people) were selected by convenience sampling. They were randomly assigned to the experimental group and the control group. The experimental group received the SFBCT, while the control group did not. The research measurement instrument comprised the ENRICHES Couple Scale (ECS). Multivariate analyses of covariance (MANCOVA) models were used to test the study hypothesis. The results showed that marital satisfaction increased among prisoners and their wives. So the principles and techniques of SFBCT did have an effect on marital satisfaction of this particular group.
