Associations between health-related quality of life, infertility-related psychological well-being, and relationship quality in individuals with endometriosis: A cross-sectional study.

Background: Endometriosis is the most frequent gynecological diseases and accompanied by both physical and psychological symptoms. An increasing number of studies suggested acknowledging endometriosis as a systematic disease due to the multifactorial effects throughout the body. The chronic disease significantly impacts daily life, including romantic relationships. This study aimed to investigate the associations between health-related quality of life (HRQoL), infertility-related psychological well-being (IPW), constructive communication, and relationship quality in individuals with endometriosis.

Methods: A total of 627 individuals with endometriosis participated in this online cross-sectional study. We measured HRQoL in all participants and IPW specifically in those who reported an unfulfilled wish for a child. Additionally, relationship quality and constructive communication were assessed. We used Pearson's product moment correlation to examine the association of HRQoL/IPW and relationship quality. Mediation analysis was used to assess the role of constructive communication in the association between HRQoL/IPW and relationship quality. In an explorative analysis, differences between subsamples with and without an unfulfilled wish for a child were analyzed.

Results: Poorer HRQoL was associated with lower relationship quality overall (p = .002) and specifically with three subscales of relationship quality: worse sexuality (p = .016), increased mistrust towards the partner (p < .001), and restriction of freedom/independence (p = .003). There was no significant association between IPW and relationship quality. The mediation analysis including constructive communication as mediator showed a full mediation between HRQoL/IPW and relationship quality. The subsamples with and without an unfulfilled wish for a child differed in HRQoL but not in relationship quality or constructive communication.

Conclusion: The findings indicated an association between HRQoL in individuals with endometriosis and relationship quality. In addition, we observed a full mediation between HRQoL/IPW and relationship quality, when constructive communication was considered as a mediator. Therefore, constructive communication plays a key role in effectively managing the impact of the disease within a relationship. Individuals with endometriosis experiencing difficulties conceiving should have access to appropriate psychological counseling.
