Note. Aggression scores are (a) higher of female and male report in each couple for the alcoholic sample and (b) partner report (i.e., male report of female aggression and female report of male aggression) for the comparison sample. N's for BCT show the number of matched pairs in the alcoholic and nonalcoholic samples included in the group comparisons.
The alcoholic sample had significantly greater aggression on this measure in the year before BCT than their respective counterparts in the matched nonalcoholic sample. Statistical test values follow.
For prevalence of aggression, values of McNemar's chi-square test (df = 1, N = 103, p < .001) for female (F)- and male (M)-perpetrated aggression were: (a) elevated verbal aggression = 46.82, r=.56 (F); 41.60, r=.54 (M); (b) overall violence = 33.75, r=.50 (F); 33.01, r=.49 (M); and (c) severe violence = 30.72, r=.48 (F); 8.28, r=.30 (M).
For frequency of aggression, values of paired sample t-test (2-tailed, df = 102) were: (a) verbal aggression = 9.98, p < .001, r=.30 (F); 7.68, p < .001, r=.27 (M); (b) overall violence = 4.69, p < .001, r=.21 (F); 3.37, p = .001, r=.18 (M); and (c) severe violence = 4.18, p < .001, r=.20 (F); 2.18, p =.03, r=.14 (M).
This score is significantly reduced from the year before BCT. Statistical test values follow.
For prevalence of aggression, values of McNemar's chi-square test (df = 1, N = 91 for Yr-1 and 86 for Yr-2) for female (F)- and Male (M)- perpetrated aggression were: (a) elevated verbal aggression = 32.03, p < .001, r=.51 (F yr-1); 36.21, p < .001, r=.54 (F yr-2); 22.78, p < .001, r=.45 (M yr-1); 33.23, p < .001, r=.53 (M yr-2); (b) overall violence = 22.88, p < .001, r=.45 (F yr-1); 28.20, p < .001, r=.50 (F yr-2); 15.56, p < .001, r=.38 (M yr-1); 33.58, p < .001, r=.53 (M yr-2); and (c) severe violence = 20.49, p < .001, r=.43 (F yr-1); 21.19, p < .001, r=.44 (F yr-2); 1.04 p = .31, r=.11, (M yr-1); 6.86 p < .01, r=.27, (M yr-2).
For frequency of aggression, values of paired sample t-test (2-tailed, df = 90 yr-1 and 85 yr-2) were: (a) verbal aggression = 9.07, p < .001, r=.38 (F yr-1); 9.03, p < .001, r=.29 (F yr-2); 6.93, p < .001, r=.44 (M yr-1); 6.93, p < .001, r=.33 (M yr-2); (b) overall violence = 7.11, p < .001, r=.31 (F yr-1); 7.46, p < .001, r=.28 (F yr-2); 5.18, p < .001, r=.37 (M yr-1); 7.35, p < .001, r=.29 (M yr-2); and (c) severe violence = 6.06, p < .001, r=.34 (F yr-1); 5.87, p < .001, r=.15 (F yr-2); 1.55, p = .13, r=.16 (M yr-1); 3.24, p < .01 r=.15 (M yr-2).
