Popis: Background: Bipolar affective disorders are dimensional illnesses in which patients experience, during the long-term course of illness, fluctuating levels of severity of manic and depressive symptoms interspersed with symptom-free periods. It is a highly exhausting and relapsing psychiatric disorder associated with significant morbidity and comorbidity. The World Health Organization Disability Assessment Schedule (WHODAS) is an International Classification of Functioning-based multidimensional instrument that was developed for measuring disability. Aim and Objective: The present study aimed to check the correlation and inter-rater agreement amongst the patient, caregiver, and clinician-administered version of the WHODAS 2.0 among persons with bipolar affective disorder. Materials and Methods: The study was cross-sectional in nature. Thirty samples of patients with bipolar affective disorder as per ICD-10 criteria were selected using a consecutive sampling technique. Patients above 18 years of age with a total duration of illness of at least more than 2 years were included and used self, proxy, and interviewer-administered versions of WHODAS 2.0. Results: The total score of WHODAS 2.0 shows that the interclass correlation coefficient between the patient and caregiver, caregiver and clinician, and patient and clinician was 0.655 (0.469–0.802), 0.599 (0.395–0.767), and 0.722 (0.586–0.820), respectively, indicative of moderate reliability. Caregivers showed a higher mean in cognition, 3.73 (3.13); mobility, 2.63 (1.73); and self-care, 0.867 (1.25), than other raters. Clinicians showed a higher mean (standard deviation) in getting along with people, 4.13 (1.69); life activities of the household, 5.46 (2.67); and participation in society, 10.70 (2.56), than other raters. Conclusion: People suffering from bipolar affective disorder are prone to disability albeit in the mild-to-moderate variety. The findings show that there was moderate reliability between the patient and caregiver, caregiver and clinician, and patient and clinician among the patient rated, caregiver rated on the overscore of WHODAS 2.0.
