Figure 1. Relationship between changes in punishment of partner drinking from time 1 to time 2 and changes in partner’s highest number of drinks on a typical day.
Note: Following Aiken and West (1991) and Cohen, Cohen, West, and Aiken (2003), lines are graphed at 1 SD above and below the mean change in punishment from baseline. Simple slopes tests for difference from 0 were: WBI b = −0.51, SE = 0.09, t(109) = −5.49, p < .001; Control b = −0.25, SE = 0.14, t(65) = −1.82, p = .07.
