“…During the 1990s and continuing to the present day, researchers influenced by family systems principles began to examine the correlations among parenting effectiveness, distress between the parents, and children's outcomes (Cummings & Davies, 1994; Grych, Fincham, Jouriles, & McDonald, ). More recent studies replicate and extend the early conclusions: In both middle‐class (P. Cowan & Cowan, ; Harold, Elam, Lewis, Rice, & Thapar, ) and low‐income (Adler‐Baeder et al, ; Conger, Cui, & Lorenz, ) families, when parents are more collaborative and able to resolve their differences, mothers and fathers are observed to have warmer, more sensitive, and appropriate limit‐setting interactions with their children or adolescents; in turn, the children score higher on academic achievement tests and are described by research staff and teachers as having fewer behavior problems than children of parents with more combative relationships.…”
