Maternal Personality Change From Pregnancy Until 12 Months Postpartum: Associations With Parenting

Although many studies have shown that personality-as a relatively stable characteristic-is a predictor of parenting behavior, personality changes occur during adulthood. Therefore, we do not know whether previous findings based on personality assessed (long) after the birth of the child indicate that personality as assessed before the child is born predicts behaviors parents eventually display. Possibly, personality changes are additionally predictive for parenting behavior. With this three-wave longitudinal study, we aimed to examine whether mothers' personality change from pregnancy to postpartum predicts maternal parenting behavior above and beyond personality traits as assessed during pregnancy. A sample of 239 pregnant women participated in the study (M-age = 29.95 years, SD = 4.08, range 20-43; 53% primiparous; 95% of Dutch descent). Women reported their big five personality traits during pregnancy (T1), at six- (T2), and 12 months postpartum (T3). At the postpartum assessments, mothers also reported on their affectionate and hostile parenting behavior. Latent Difference Score models indicated that personality at T1 predicted hostile but not affectionate parenting behavior at T2. Changes in personality from T1 to T2 were associated with maternal hostile and affectionate parenting at T2, whereas changes from T2 to T3 were unrelated to parenting. Personality as assessed during pregnancy may thus be helpful in identifying mothers at risk of early hostile parenting behavior. Identifying predictors of personality change may inform preventive efforts aimed at reducing this risk, as personality changes from pregnancy to 6 months postpartum were more predictive of maternal parenting than initial levels.
