The development of disability scales for childhood and adolescent injuries

Scales for the study of injury-induced disabilities among 0-17 year olds were developed. Telephone interviews were conducted among parents of injured children (n = 432) 6 months after hospitalization in the three main hospitals of Jerusalem, about disabilities immediately following and 6 months after the injury. The scale for 4-17 year olds included 25 items derived from the International Classification of Disabilities, Impairments and Handicaps. Factor analysis revealed three dimensions of disability: personal care and daily activities; motor activities; and communication and sensory activities. The scale and the derived subscales on personal care and daily activities, and on motor activities showed high Cronbach's alpha, especially for disabilities immediately after the injury. The scale or subscales are easy to use, related to everyday activities performed by children in all cultures, are not related to the characteristics of the respondents, and have high consistency-reliability and construct validity. They may be used to assess the prevalence of disabilities in population studies.
