The modified 47-item instrument was mailed to a sample of alumni with disabilities (N = 1,176) from a major Midwestern university. A total of 411 surveys were returned, representing a 35% return rate. For the purpose of the present study, only alumni with physical disabilities (N = 372) were included in the data analyses. Overall, this is an educated sample, with a good family income. Among them, 227 (61.02%) were men and 145 (38.98%) were women; 342 (93.44%) were White, 13 (3.55%) were Black, and 11 (30.56%) were of other racial or ethnic origins; 124 (33.4%) had college degrees and 242 (65.2%) had graduate or professional degrees; 70 (19.0%) had an annual family income between $35,000 to $49,000 and 115 (31.3%) had an income between $50,000-74,999. The mean number of years in which the respondents had lived with a disability was 36.9, with a SD of 14.9. Without any assistance, 112 (31.5%) responded that they could walk more than 150 feet, 11 (3.1%) could walk 50 to 150 feet, 23 (6.5%) could walk less than 5 0 feet, and 210 (59%) reported that they could not walk at all. To determine the factorial construct of the instrument, their response scores were analyzed by a factor analysis with principle component extraction and Varimax orthorgonal rotations. …
