The present study has been analyzed 30 scales and 52 studies relevant to adaptive behaviour assessment of children with intellectual disability (CWID) to identify the common structure and psychometric characteristics of the adaptive behaviour scales (ABSs) of CWID. The analyzed studies and scales were administered and standardized on samples of CWID in 15 countries around the world. Qualitative analysis using triangulation analysis method and quantitative analysis using frequencies and percentages were done to attain the objectives of the study. The results revealed that there are 5 common domains and 19 sub-domains that need to be considered while developing the ABSs for CWID. The main domains include daily living skills, communication skills, social skills, motor skills, and academic and conceptual skills. It was also found that 8 methods of validity and 6 methods of reliability were used for standardizing the scales. The most commonly used methods were construct validity, concurrent validity, test-retest reliability, inter-rater reliability and internal consistency. All the reviewed studies of factor analysis emphasized on the multidimensional structure of ABSs which ranged from two-factor model to five-factor model. The results of this study may help the researchers in the field to understand the common structure and standardization methods to be considered and adopted while developing and standardizing the ABSs for CWID.

In the 19th century, mental retardation was recognized principally in terms of a number of factors that included awareness and understanding of surroundings, ability to engage in regular economic and social life, dependence on others, the ability to maintain one's basic health and safety, and individual responsibility (Brockley, 1999). Today, fulfillment of these personal and social responsibilities, as well as the performance of many other culturally typical behaviors and roles, constitutes adaptive behavior. Adaptive behaviour assessment scales of CWID, in the contemporary time, have a crucial role in the diagnostic process and preparing the educational programmes for those children. The importance of adaptive behaviour assessment in the field of intellectual disability is resulted from the obvious effect of the intellectual disability on the normative behaviour of CWID and their deficits to meet the living requirement as per the norms of the society. Adaptive behaviour assessment measures began to appear during the 1920s when Doll, Kuhlmann, and Porteus sought to develop assessment practices consistent with a definition of mental retardation that emphasized adaptive behavior and social competence. Edgar A. Doll developed the Vineland Social Maturity Scale (Vineland SMS) in
