β, beta-coefficient from multilevel analyses with measurement occasions (Level 1) nested within persons (Level 2) nested within couples (Level 3), adjusted for age at baseline and all predictors of the main model in Table 2 (the main model was repeated five times, i.e., separately for each Big Five trait). CI, confidence interval; p, p-value. Early-postpartum effect: Changes in perceived social support from pregnancy to early postpartum (i.e., 4 months postpartum in MARI and 14 months postpartum in DREAM). Late-postpartum effect: Further changes in perceived social support until late postpartum (i.e., 16 months postpartum in MARI and 2 years postpartum in DREAM). Significant effects (p < 0.05) are printed in bold.
