Patterns of Marital Relationship Change Across the Transition From One Child to Two

Patterns of marital change after the birth of a second child were explored in a sample of 229 married couples, starting in pregnancy, and at 1, 4, 8 and 12 months postpartum. Five trajectory patterns that reflected sudden, persistent decline (i.e., crisis), sudden, short-term decline (i.e., adjustment and adaptation), sudden, short-term gain (i.e., honeymoon effect), linear change, and no change were examined with dyadic, longitudinal data for husbands and wives. Six distinct latent classes emerged using growth mixture modeling: (a) wife decreasing positivity-husband honeymoon (44%), (b) wife increasing negativity-husband adjustment and adaptation (34.5%), (c) wife honeymoon-discrepant marital positivity (7.4%), (d) wife adjustment and adaptation (6.9%), (e) couple honeymoon with discrepant positivity and negativity (5.2%) and (f) husband adjustment and adaptation (1.7%). Classes were distinguished by individual vulnerabilities (i.e., depression, personality), stresses associated with the transition (i.e., unplanned pregnancy), and adaptive processes (i.e., marital communication, social support). Marital communication, parental depression, and social support emerged as important targets for intervention that can assist parents planning to have additional children.
