Abstract
Most individuals who develop Major Depressive Disorder (MDD) will experience a recurrent depressive episode; we know little, however, about cognitive mechanisms that increase the likelihood of recurrence. In the current study we examined whether negatively biased self-referential processing, negative life events, baseline depressive symptoms, and psychotropic medication use predicted the onset of a subsequent depressive episode in a longitudinal study of women with a history of recurrent MDD. Higher levels of depressive symptoms at baseline predicted experiencing a greater number of negative life events which, in turn, tended to predict recurrence of depression. Importantly, after accounting for other associations, negatively biased self-referential processing contributed unique variance to the likelihood of experiencing a depressive episode over the next three years. Thus, negatively biased self-referential processing appears to be a significant risk factor for the recurrence of depressive episodes and may be an important target for interventions aimed at preventing future episodes.
