Impairment and distress associated with relationship discord in a national sample of married or cohabiting adults

The clinical importance of relationship discord was examined through evaluating the association between relationship discord and multiple measures of impairment and psychological distress in a population-based sample of married and cohabiting adults (N = 2,677). In comparison to people that were not in discordant relationships, individuals in discordant relationships reported greater social role impairment with relatives and friends and greater work role impairment. They also reported higher levels of general distress and poorer perceived health and were more likely to report suicide ideation. With the exception of suicide ideation, the associations between relationship discord and impairment and psychological distress remained significant when controlling for current mood, anxiety, and substance use disorders, suggesting that relationship discord is incrementally related to impairment and psychological distress over and above the effects of psychiatric disorders.
