Objective The current investigation aimed at studying the sociodemographic, clinical, and neuropsychological variables related to functional outcome in a sample of euthymic patients with bipolar disorder( BD ) presenting moderate‐severe levels of functional impairment. Methods Two‐hundred and thirty‐nine participants with BD disorders and with Functioning Assessment Short Test( FAST ) scores equal or above 18 were administered a clinical and diagnostic interview, and the administration of mood measure scales and a comprehensive neuropsychological battery. Analyses involved preliminary Pearson bivariate correlations to identify sociodemographic and clinical variables associated with the FAST total score. Regarding neuropsychological variables, a principal component analysis ( PCA ) was performed to group the variables in orthogonal factors. Finally, a hierarchical multiple regression was run. Results The best fitting model for the variables associated with functioning was a linear combination of gender, age, estimated IQ , Hamilton Depression Rating Scale ( HAM ‐D), number of previous manic episodes, Factor 1 and Factor 2 extracted from the PCA . The model, including all these previous variables, explained up to 29.4% of the observed variance. Conclusions Male gender, older age, lower premorbid IQ , subdepressive symptoms, higher number of manic episodes, and lower performance in verbal memory, working memory, verbal fluency, and processing speed were associated with lower functioning in patients with BD .
