Notes: Differences between husbands and wives are significant for each variable (p < .001). The variable frequent heavy drinking was the maximum of the frequency of intoxication in the past year and frequency of six or more drinks (range 0-9). The marital alcohol problem variables was the frequency of 7 alcohol-related problems occurring in the past year that related to the marriage (range 0-28) and the other problems was the frequency of 18 alcohol-related problems occurring in the past year that were not related to the marriage (range 0-72). Depression was assessed with CES-D (range 0-60). For all scales, higher scores indicate greater impairment.
