Validation of Urdu Interaction with Disabled Persons scale

This study developed a valid and reliable Urdu language measure that can be used for assessing attitudes toward persons with physical disability in Pakistan. The Interaction with Disabled Persons scale (IDP), which measures attitudes of discomfort with interaction with disabled people, is a scale with established validity and reliability in English and other languages. An Urdu translation was back-translated to English and then reviewed by a committee to develop cultural validity. Data were collected from 591 Urdu-speaking Pakistani people. Factor analysis extracted four factors that accounted for 55% of the variance and reflected factors found in 12 previous studies. Cronbach's alpha described moderate internal consistency for the IDP.
