Note. MAdj = Post mean adjusted for pretest levels; M = Mean, SD = Standard Deviation, Adj = Adjusted. Significant effects are shown as bolded text after applying a Bonferroni correction to alpha within each of the three domains (critical p-values for parenting, family, and couple domains were .010, .013, and .008, respectively).
