  1. All correlations were significant at p < .05 except for correlation between T1 physical health and T4 social health (p=.13). *weak relationship, **medium relationship, ***strong relationship based on Cohen’s criteria of power. T1 = 25–29 gestational weeks; T2 = 30–34 gestational weeks; T3= over 34 gestational weeks; T4 = 4–6 weeks postpartum.
