Chunk #23 — Results — Frontal EEG Asymmetry as a Function of Lifetime DSM-IV-Defined Depression — Follow-up analyses: Current MDD status and depression severity
and MDD- groups. Based on EEG asymmetry results, the main effect of current MDD status was the effect of importance. Figure 2 illustrates that a main effect of current MDD status emerged (F(2, 297) = 14.1, p < .001), indicating that the current MDD+ group and past MDD+ group displayed relatively less left frontal activity than the MDD- group (both p < .001 and d = .57 and .58, respectively), but did not differ significantly from each other. These findings suggest that the previously-reported effects of lifetime MDD were not accounted for solely by those with current MDD, as individuals with past MDD appear indistinguishable from those with current MDD in terms of frontal EEG asymmetry.
