Spouse concordance for alcohol dependence and heavy drinking: evidence from a community sample.

Using data from a community sample of 586 married couples, levels of spouse concordance for lifetime and current alcohol dependence and heavy drinking were estimated. In addition, marital quality ratings in concordant and discordant couples were compared. Spouse concordance was significant for lifetime alcohol dependence and for both lifetime and current heavy drinking. Marital quality varied as a function of current heavy drinking and alcohol dependence such that members of couples in which neither spouse drank heavily reported better marital quality than other couples. Furthermore, although marital quality did not differ significantly between concordant and discordant couples, couples concordant for current heavy drinking consistently reported poorer marital quality than other couples.
