Objective: The aim of this study was to test a structural model of hypothesized relationships among spiritual well-being, intervening variables personal worth of self and others, commitment to relationship stability, commitment to relationship growth, positive interaction/appreciation, communication/conflict resolution, time spent together, and the dependent variable dyadic adjustment. Methods: Two hundred and forty seven (153 females and 94 males) married parent subjects were selected by convenience sampling from three universities in Mazandaran, Iran to take part in this study. They were all volunteers and were not paid and their age range was 23-61 (31.35 ± 5.01 years). All participants were asked to complete the Spiritual Well-Being Scale (SWBS), the Family Strengths Scale (FSS), and the Revised Dyadic Adjustment Scale (RDAS). Results: The results from structural equation modeling confirmed a hierarchy for the development of family strengths, and indicated that spiritual well-being and strength in most of the characteristics affected dyadic adjustment at statistically significant levels (p< 0.01). Conclusion: Couples’ level of dyadic adjustment is increased when they have higher spiritual well-being, value each other, make a commitment to each other, communicate well, enjoy being with each other, and spend time together.
