Family stability, defined as the consistency of family activities and routines, was examined in a sample of urban families (n = 70) with children (ages 7 to 16) receiving psychological services. Parent-reported family stability was associated with lower parent-reported children's internalizing behavior problems. Child-reported family stability significantly attenuated the influence of parental depressive symptoms on parent-reported children's internalizing, externalizing, and total behavior problems, while controlling for the effect of children's age. Parental depressive symptoms were associated with problems in child adjustment only at the low level of family stability.
