BackgroundAgood romantic relationship quality increases resilience against mental and physical health problems. Regarding correlates of relationship quality, research has focused mostly on attachment style and personality traits such as the Big Five.ObjectiveThe current study aims to find further predictors of agood relationship quality, such as sleep, demographics, and the boundary concept.Materials and methodsFor the study, 336subjects were recruited, most of them women (79.76%). Only participants who were in arelationship were included in the analyses (N=216). The effects of sleep (Pittsburgh Sleep Quality Index, PSQI), demographics, and thin or thick boundaries (Boundary Personality Questionnaire, BPQ) on relationship quality (PartnerschaftsfragebogenKurzversion, PFB-K) were assessed using multiple regression.ResultsAge and thickness of boundaries were significantly connected with relationship quality. Sleep quality, gender, body mass index, and accommodation were not related to relationship quality.ConclusionThe current study confirms the importance of age and provides new insight into the effects of boundaries in terms of relationship quality. Methodological limitations (e.g., homogenous and healthy sample) might compromise the findings regarding sleep. Future studies should include amore diverse sample and investigate further correlates of the boundary concept.
