In all the patients of both groups, relevant scales, that is, back depression inventory and global assessment of functioning (GAF) were applied. These data were statistically analyzed by SPSS software.
Results: On Comparison of global assessment of functioning scores between both groups the GAF score in bipolar depressive patients (SD ± 50.03 [4.75]) had significantly lower score as compared to unipolar depressive patients (62.37 [SD ± 11.50]), also patients show significant negative correlation. (−0.559) of GAF score and total Beck Depression Inventory score in case group (bipolar depressive patients).
Conclusion: These findings of greater impairment in global functioning may be interpreted by understanding that life of patients with bipolar depression also complicated by having episode or episodes of manic symptoms in addition to their depressive episodes while patients with unipolar depression are experiencing depressive episodes only.
