Sexual functioning in patients with multiple sclerosis and its association with social support and self-esteem

Sexual dysfunction is very commonly reported by people with multiple sclerosis (MS). However, this problem often remains under-diagnosed and under-treated. Furthermore, still very little is known about protective psychosocial factors that may help to improve sexual functioning in MS patients. Thus, we aimed to assess the associations between social support, self-esteem and sexual functioning in MS patients when controlled for clinical and sociodemographic variables. The Expanded Disability Status Scale (EDSS), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Rosenberg Scale of Self-esteem (RSE) were used to assess the independent variables. Sexual functioning was assessed by the Incapacity Status Scale (ISS). We found a significant association between social support and sexual functioning (p = 0.01). However, this association attenuated (p < 0.05) when self-esteem (p < 0.01) was added to the model. Furthermore, we found that sexual dysfunction in MS patients was associated with older age (p < 0.001). Self-esteem was associated with sexual functioning more strongly compared to social support and sexual functioning, even though both of these variables were associated with sexual functioning as well. Our findings support the biopsychosocial model of treatment of sexual dysfunction in MS patients.
