| Abstract: | Drawing upon existing theory and research on attitudes to towards people with disabilities, L. Gething (1991) used Australian samples to develop the Interaction with Disabled Persons (IDP) Scale, which reflects 4 key attitude components (e.g., fear of becoming disabled). The IDP scale was used with a sample of 231 Canadian management undergraduates (aged 19-51 yrs) to examine the IDP scale's psychometric properties; to test Gething's (1994) 6-factor model; and to test D. MacLean and P. M. Gannon's (1995) 2-factor model using confirmatory factor analysis. Overall, the findings did not support the 6- or 2-factor models. There was poor to moderate internal consistency reliability for most scales, and small social desirability effects. Results show that further refinement to the IDP scale is required to improve its factor structure, internal consistency reliability, and to minimize correlations with social desirability.
