This study employed James M. Donovan's five step object relations couple therapy model to resolve the conflicts between couples living in a relationship akin to marriage and to investigate the effects of couple therapy intervention. The participants chosen for this study were couples living in a relationship akin to marriage. They received 10 sessions of art therapy. The data was analyzed qualitatively using Miles and Huberman's matrix and network. The findings are as follows: First, the five aspects found in the couples’ conflicts were ‘stress and frequent fights’, ‘wife overly pressuring the husband to be an ideal father to the children’, ‘mutual frustrations’, ‘emotional outbursts’ and criticisms’ and ‘wife ignoring and finding faults in the husband.’ Second, the factors causing the couples’ conflicts came from the solutions the participants had tried, which ware counter-productive solutions related to their parents. Third, The therapist’s responsibilities included providing the holding environment, interpretation, facing the relationship, each spouse's reflection of emotions, and playing a mediator role. The couple art therapy intervention included allowing free expression, the experience of regression, the experience of truth, the perception of the immediateness, and the sharing of pleasure. Fourth, three effect factors were established: more understanding of the spouse, functional communication improvement, and behavior change.
