Adaptive Functioning being a socio-developmental construct varies according to neuro-developmental milestones and equivalent biologically and socio-culturally expected ‘standard’, thus requiring culturally adapted or culture sensitive tools to measure it. For this reason, aim of the study is to culturally adapt the Vineland Adaptive Behaviour Scale, Second Edition (Vineland-II), Survey Form (Sparrow et al., 2005) into Bengali language considering Bengali context with evaluating the psychometric properties. The research was a cross sectional study design in which current adaptive functioning and intellectual functioning by Binet Kamat Test of Intelligence, (Kamat, 1958) were used. 212 neuro-typically developing children (including 101 boys & 111 girls), with age range from 6 to 18 years, having 90 intellectual quotient score were selected following purposive sampling from five zones of Kolkata. For adaptation purpose, all items were translated in Bengali language and content of 13 items were culturally adapted. The result scale denotes good inter-rater reliability, range lying between 0.72-0.83 (kappa coefficient) and internal consistency reliability, range lying between 0.68 – 0.83 (split half reliability) and good content validity (X- 4.3, S.D – 0.79). It is also observed that the social age (X- 104.5 months) based on adapted (VABS II) is comparably low than the participants’ mental age (X-129 months) and chronological age (X-132 months), (social age < mental age < chronological age) of the same group of neuro-typically developing participants. This finding indicates that adaptation process will only be completed if the standardization procedure is done on the normative population itself along with adaptation of test items ; culture specific item is not only required but also development of culture specific age norm is required.
