Maternal stress While sum scores of maternal stress reveal no difference between both intervention groups at T3 [F(1, 8) = 2.92; p = .126; eta 2 = .190], the maternal distress subscale was higher at T3 in CAU group (M CAU = 75.7) compared to PIP group (M PIP = 60.2), an effect that approached significance in the ANCOVA [F(1, 8) = 4.34; p = .063; eta 2 = .192].
