Abstract: Objectives: To assess and compare the changes in disability scores associated with Bipolar Depression (BD) and Unipolar Depression (UD) over 1 year. Methods: A longitudinal study was taken up in adults diagnosed with unipolar or bipolar depressive disorder with current depressive episode. Diagnosis was made according to Schedule for Clinical Assessment in Neuropsychiatry. Severity scoring was done using Hamilton’s Depression (HAM-D) rating scale and Hamilton’s Anxiety (HAM-A) rating scale. Disability was assessed using Indian Disability Evaluation and Assessment Scale (IDEAS) and London handicap Scale (LHS) at baseline, 6 and 12 months. Results: Sixty participants were recruited (42 UD and 18 BD). No significant differences were seen in socio-demographic parameters, except higher education levels and males being overrepresented in UD. Significant differences at baseline were seen in HAM-D ( p  = .001) and HAM-A ( p  = .003) scores. The extent of disability was seen to correlate with severity of illness only in case of BD at baseline. No significant differences were seen in the IDEAS scores at baseline. IDEAS score improved at each follow-up assessment ( p   40%) were comparable at baseline but were significantly more in the BD at 12-months ( p  = .049). Conclusion and implications: Disability in psychiatry occurs equally amongst unipolar and bipolar depressive disorders and tends to improve over time, although the level of improvement may differ. It may not always correspond to severity of illness. These factors should be considered while certifying disability.
