Sexual dysfunction, depression, and marital dissatisfaction among Brazilian couples

Abstract

AbstractBackgroundHealth professionals treating sexual dysfunction and relational dissatisfaction recognize that they are multifactorial phenomena, and depression can be bidirectionally associated with both.AimThe purpose of this study was to investigate sexual dysfunction in heterosexual couples in relation to the quality of their marital relationship and depression symptoms.MethodsThe sample consisted of 100 heterosexual couples recruited in Brazil. Both partners of each couple completed the Golombok-Rust Inventory of Sexual Satisfaction and the Golombok-Rust Inventory of Marital Satisfaction, which were translated and adapted, and the Beck Depression Inventory, which was validated for the Brazilian population. Both partners completed their questionnaires separately, and the couple’s surveys were linked to preserve conjugal data for dyadic analysis. The Actor-Partner Interdependence Model was used to understand how sexual dysfunction in couples is related to depression and relationship quality among and between partners.ResultsSexual dysfunction was found to be strongly associated with dissatisfaction in the relationship (husbands, β = 0.57, P < 0.001; wives, β = 0.60, P < 0.001), and a positive association was found between depressive symptoms and marital dissatisfaction (husbands, β = .32, P < .001; wives β = .40, P < .001).Clinical ImplicationThe results suggest that it is important for health professionals to be aware of the dyadic impact of struggles with both sex and the relationship and the presence of depression symptoms in patients who seek care for sexual complaints or depression and who are in a marital relationship.Strengths and LimitationsThe different results found for men and women may shed light on the biopsychosocial dimensions of human sexuality. When treated as a purely physical experience, sex is myopic. In this study we demonstrated psychosocial aspects associated with gender and sexuality, and the partner’s variables were found to have a greater impact on women than they did on the men. A limitation of this study is that the sample is not generalizable as it is not demographically representative of all socioeconomic groups in Brazil. Furthermore, the participants in this sample did not have clinical levels of depression, so the results cannot be extended to couples in which one or both spouses have depressive disorder.ConclusionIt was found that sexual dysfunction is strongly associated with the quality of the couple relationship, and that the quality of relationship plays a mediating role between depression and marital quality, especially for the women.
