abstract
BACKGROUND: Bipolar disorder (BD) represents a chronic and recurrent illness that can lead to severe disruptions in family, social, and occupational functioning. The severity of mood symptomatology has been associated with functional impairment in this population. However, the majority of studies have assessed global functioning without considering specific domains. The main objective of the current study was to assess specific life domains of functioning as well as the overall functioning in patients with BD across different mood states ([hypo] mania, depression, or euthymia) compared with healthy controls by the means of a standardized scale validated for BD. METHODS: The sample included 131 subjects with BD (68 in remission, 31 hypo [manic], and 32 depressed) and 61 healthy controls. The Functioning Assessment Short Test was used to assess overall and multiple areas of functional impairment (autonomy, occupational functioning, cognitive functioning, interpersonal relationships, financial issues, and leisure time). RESULTS: The results showed significant intergroup differences; depressed patients had the lowest functioning (48.03 ± 12.38) followed by (hypo) manic patients (39.81 ± 13.99). The euthymic group showed least impairment in functioning compared with the depression and (hypo) mania groups (11.76 ± 12.73) but still displayed significant impairment when compared with the healthy control group (5.93 ± 4.43). CONCLUSIONS: This study indicates that depressive symptoms are associated with greater negative impact on psychosocial functioning than (hypo) manic symptoms. Further deficits in functioning seem to persist during remission. The results highlight the importance of aggressively treating depression and mania and the need to develop psychosocial interventions targeting to improve functional outcomes.
