Mean number of WM errors produced on the SPWM task (top panel) and SOP task (bottom panel). Preg+ = pregnant women who were depressed; Preg− = pregnant women who were not depressed; PostPart = postpartum controls; NonPreg = non-pregnant controls. Bars represent the standard error of the mean. The two subgroups of pregnant women (Preg+, Preg−) differed markedly from one another in their patterns of WM performance. Preg− women showed excellent WM, making significantly fewer WM errors than NonPreg controls on the SPWM (p = .013) with the same trend seen on the SOP (p = .069). In contrast, Preg+ women, who were pregnant but exhibited antepartum depression, committed elevated numbers of WM errors and differed significantly (p = .014 and p = .006 on the SPWM and SOP respectively) from their non-depressed counterparts (Preg−) on both tasks. The Preg+ and Preg− groups were matched on gestational stage, parity, age, and education but differed in levels of depressive affect.
