The purpose of this study was to compare the functional performance profiles of men and women with chronic obstructive pulmonary disease, describe the extent to which physiologic impairment, physical symptoms, and psychosocial resources contribute in a cumulative manner to performance, and outline the extent to which these contributions differ across gender. Secondary data analyses were employed. Although women ( n = 45) reported more functional difficulty than men ( n = 44) in 9 of 12 Sickness Impact Profile categories, the differences were not significant. Using hierarchical regression procedures, physiologic, symptomatic, and interactive variables predicted total ( R 2 = .64) and physical performance ( R 2 = .52), while symptomatic and psychosocial variables predicted psychosocial performance ( R 2 = .53). Results indicate that models of functional performance may be different for men and women. ©1995 John Wiley & Sons, Inc.
