- Abstract
Objective: to compare the performance of the DEX Questionnaire Revised in people with bipolar disorder (type I and type II) and control population, and also examine the factor structure for this questionnaire. Method: DEX-R was administrated to 120 participants with bipolar disorder (BDG) and 300 healthy controls (CG). an exploratory factor analysis, further comparisons between CG and BDG using student t-test, and comparisons using anova one way were used to explore differences among the two bipolar subgroups and CG (CG X BDG type 1 X BDG Type II). For all analyses the significance level was set at p< .05. Results: Three factors account for 58,10% of variance loaded in three dimensions. A significant difference between groups on DEX-R score total (t= 15.63; df=418; p<00.1) was found. In reference to results from comparisons among the two clinical and controls groups, the BDG type i exhibited higher impairments in general. Conclusions: the factors that loaded in three main dimensions were congruent with the functions that have been attributed to orbitofrontal, dorsolateral and anterior cingulated circuits. BDG type i exhibited a higher disability in items loaded to orbitofrontal circuit. the DEX-R appears to be a useful measure to assess executive functions in bipolar patients.
