Individuals with bipolar disorder demonstrate variable treatment trajectories and poor psychosocial functioning even when they are not highly symptomatic. This study evaluated whether the degree of impulsivity during a mixed or manic mood episode is related to decrements in psychosocial functioning in patients with bipolar I disorder, and examined clinical and cognitive predictors of time to reach euthymia within one year following hospitalization. Participants were 94 adult inpatients (60 manic) with bipolar I disorder. Baseline symptom severity was assessed using the Young Mania Rating Scale and the Montgomery Asberg Depression Rating Scale, and baseline impulsivity was measured with the Stop Signal Task, Degraded Stimulus Continuous Performance Task, Delayed Response Task, and Barratt Impulsiveness Scale. In the current sample, impulsivity was significantly higher among participants experiencing mixed than manic episodes and predicted recent psychosocial functioning among individuals in mixed episodes only. Time to reach euthymia was comparable for both groups. Predictors of a shorter time to reach euthymia for the entire sample included fewer depressive symptoms and better impulse control at baseline, as well as a later age of illness onset, shorter illness duration, and the absence of comorbid attention-deficit/hyperactivity disorder and marijuana abuse. Trait impulsivity was a significant independent predictor of time to euthymia, even after accounting for the other clinical variables.
