Ruminative Response Style and Vulnerability to Episodes of Dysphoria: Gender, Neuroticism, and Episode Duration

A number of recent laboratory and prospectivefield studies suggest that the tendency to ruminateabout dysphoric moods is associated with more severe andpersistent negative emotional experiences (e.g., Morrow & Nolen-Hoeksema, 1990;Nolen-Hoeksema & Morrow, 1991). The current paperreports two studies that tested the hypotheses that (a)ruminative response styles act as a trait vulnerabilityto dysphoria, particularly to relativelypersistent episodes of dysphoria; (b) aspects ofrumination that are not likely to be contaminated withthe presence and severity of previous symptomatology(introspection/self-isolation, self-blame) demonstrate vulnerability effects;and (c) rumination mediates the effects of gender andneuroticism on vulnerability to dysphoria. Consistentsupport was found for each of these hypotheses. Overall, our data suggest that rumination mightreflect an important cognitive manifestation ofneuroticism that increases vulnerability to episodes ofpersistent dysphoria.
