The Pulmonary Rehabilitation Adapted Index of Self-Efficacy (PRAISE) tool contains 15 items, 10 assessing “general” self-efficacy and five assessing self-efficacy specific to pulmonary rehabilitation (PR). The PRAISE tool showed a significant response following PR; however, given the task-specific nature of the self-efficacy construct,2,3 we wonder if the increase in self-efficacy was predominantly related to an improvement in the PR-specific items rather than in general self-efficacy. We believe the article would have benefitted from an analysis of individual item performance. If the improvement had been related to PR items only, it may have allowed for abbreviation of the tool. On the other hand, improvement of the general self-efficacy items would suggest that PR benefited areas other than mastery of exercise, such as problem-solving and coping skills (critical aspects of behavioral change for self-management), even though changes in behavior following PR were not measured in this study.
