Effect of stress on family functioning during pregnancy

A theoretical model hypothesized to predict family functioning was tested in four groups of expectant parents, followed by exploratory model building. The groups studied during the 24th to 34th weeks of pregnancy included 153 high-risk hospitalized women, 75 of their partners, 218 low-risk women from the general obstetric clinic, and 147 of their partners. Both partners in the high-risk situation reported greater discrepancy in family functioning than partners in the low-risk situation. The hypothesized models proved to have low explanatory power, accounting for 13% to 15% of the variance. The final empirical models developed explained 33% of the variance in family functioning among high-risk women and 48% among their partners, 23% among low-risk women, and 32% among their partners. The empirical models differed from the hypothesized models in that variables postulated to have only indirect effects were shown to have direct effects on family function and inter-generational variables significantly expanded the theoretical model.
