Attachment insecurity is a more powerful predictor of depressive symptoms in the early postnatal period than either mood disorder history or antenatal depression. When ASQ is entered into a two-step multiple regression after history of mood disorder and depression at intake, beta values for these variables are reduced by 25–50%. This proportion is greater over three months than over six months postpartum. The beta value for ASQ in the three-month regression exceeds the beta values for mood disorder history and intake EPDS, and R² values for both models are improved with the addition of ASQ. Nonsignificant covariates included in these models but not shown in the table include age, marital status, parity, planned pregnancy, education, employment, ethnicity, and rating of partner relationship, none of which made significant contributions to the model. Results for CESD outcome are similar (not shown).
