BackgroundStudies have shown that sleep quality is negatively affected by perfectionism. Moreover, partner- or relationship-oriented perfectionism negatively influences relationship quality.ObjectiveThis paper aims to investigate the association of general perfectionism with sleep quality and relationship quality.Materials and methodsA study assessing perfectionism, sleep quality, and relationship quality was performed via analyzing online questionnaires completed by 489 German adults from the general population.ResultsParticipants with impaired sleep showed ahigher level of maladaptive perfectionism (concern over mistakes and doubts, parental expectations, and criticism) than participants with good sleep, whereby the severity of sleep problems was not determining. Relationship quality is affected by perfectionism. However, this association is mediated by sleep quality.ConclusionPerfectionism is associated with worse sleep quality but not with worse relationship quality when sleep quality is integrated into the model as amediator.
