Introduction: The Young Mania Rating Scale (YMRS) is widely used clinician-rated instrument which measures the symptom severity of mania and considered as ʺgold standardʺ. We aimed to assess the psychometric properties of Bangla YMRS.

Methods: Current validation study was performed from January 2015 to September 2016 among patients of mania of department of psychiatry of Bangabandhu Sheikh Mujib Medical University, Dhaka. The adaptation of YMRS to Bangla was achieved according to the standard process of forward-backward translation. Data were collected from 51 manic patients and analyzed different forms of reliability and validity by Statistical Package for the Social Science version 16.0 software.

Results: The Cronbach's alpha value was 0.89 and interrater reliability was measured by Cohen kappa coefficient and ranged from 0.80 to 0.98 those signifies an acceptable reliability statistic. Face validity and content validity were assessed systematically and construct validity was assessed by factor analysis. Only 1 factor was were extracted by exploratory factor analysis with varimax rotation signifying the unidirectionality of the construct.

Conclusions: Bangla YMRS can be a psychometrically reliable and valid tool to use in clinical settings, research and primary care setting to assess the symptom severity of mania as well as the relapse of episode.
