Abstract Background Research suggests that patients satisfaction with their physical functioning SPF is a critical component of HRQL. This study was designed to examine the extent to which perceptions of physical function and the value placed on physical function are related to satisfaction ratings. The sample consisted of older adults suffering from a progressively debilitating disease chronic obstructive pulmonary disease COPD . Methods During baseline assessments COPD patients participating in a randomized controlled physical activity trial completed measures of SPF perceived difficulty and perceived importance. Results An ANCOVA controlling for age and gender indicated that perceived difficulty perceived importance and their interaction accounted for 43 of the variance in SPF. Additionally participants were most satisfied with important tasks that they performed with little difficulty. Participants were least satisfied with important tasks that they perceived as highly difficult. Conclusion The results of the present study
