Activities of Daily Living (ADL) instruments have been used extensively in public health practice, research, and clinical applications. ADL’s are considered durable indicators of “activity limitations”— consistent with the World Health Organization’s dimensional framework for disability. Despite their popularity, there is a paucity of research supporting the validity and reliability (Sikkes et al 2008) of ADL scales, particularly for studies concerned with developmental disabilities.
We developed and evaluated a modified set of ADL items according to quality criteria for measurement properties of health status questionnaires proposed by Terwee et al (2007). The Waisman-ADL has been used in several longitudinal studies of adolescents and adults with substantial impairments (fragile X syndrome, autism, Down syndrome, and intellectual disability).
