“…McKenry et al., 1999; Shifflett & Cummings, 1999), while other programs (e.g., McClure, 2002; Kramer & Kowal, 1998) were evaluated using court records of divorce‐related relitigation. Five of these programs reported positive findings, such that parents either reported decreased interparental conflict (Shifflett & Cummings, 1999; Homrich, Glover, & White, 2004) or decreased relitigation (Arbuthnot et al., 1997; Criddle et al., 2003; Kramer & Kowal, 1998). However, limitations in the design of these evaluations (i.e., small sample sizes, failure to describe how the program and control groups were selected, non‐equivalent control groups that might plausibly differ on the outcome variable) preclude drawing confident conclusions concerning whether the observed effects were due to the program.…”
