Moreover, studies primarily involve families with two parents present (e.g., Beckman, 1983Beckman, , 1991McKinney & Peterson, 1987;Dyson, 1991Dyson, , 1993Gallimore et al, 1993;Krauss, 1993;Saddler et al, 1993), Some of these authors acknowledge the limitations of interpreting findings due to their sample characteristics (Beckman, 1991;Boyce et al, 1991;Dyson, 1991Dyson, , 1993.…”
