Family dynamics in families with very low birth weight and full-term infants: a pilot study.

The purpose of this pilot study was to determine differences in family health across six dimensions of functioning between families with a very low birth weight infant (VLBW) and families with a full-term infant. An epidemiologic model and Barnhill's (1979) system theory of healthy family dynamics provided the organizing framework for the study. Sixteen families with a VLBW infant and 25 families with a full-term infant were assessed for differences in family health across Barnhill's six dimensions. Independent t-tests showed no significant differences on the five dimensions of infant behavioral style. While a 2 x 3 MANOVA showed no significant differences on any of the measures by family, the Turkey HSD post hoc tests for main effect found significant differences related to the mothers' position within the family, Specifically, the position the mother maintains in the family significantly contributes to certain dimensions of family health.
