Abstract

Objectives: To examine the predictive validity, minimal important difference (MID)and responsiveness of the PRAISE tool.Design: Retrospective data analysis from HomeBase trial of home versus centrebased pulmonary rehabilitation.Setting: Tertiary health service.Participants: One hundred and sixty-six participants with COPD (100 men) withmean age 69 (standard deviation 9) years, FEV1% predicted 50% (19).Interventions: Eight-week pulmonary rehabilitation program, conducted at thehospital or at home.Main Outcome Measures: The 15-item PRAISE tool comprising 10 general and 5 pulmonary rehabilitation-specific self-efficacy questions. Predictive validity wasexamined by exploring the relationship between baseline PRAISE score andobjective change in physical activity following pulmonary rehabilitation using theSenseWear Armband. The MID was evaluated using anchor-based and distributionbasedmethods. Responsiveness was assessed with effect sizes.Results: A higher baseline PRAISE score (indicating better self-efficacy) was anindependent predictor of reduced sedentary time following pulmonary rehabilitation(p=0.03). A one point increase in PRAISE was associated with a decrease insedentary time of 4 minutes/day (95% confidence interval -7.8 to -0.4 minutes/day.Anchor-based estimates of the MID were 0.5 to 1.5 points; however sensitivity andspecificity were modest (area under the curve Conclusions: The PRAISE tool has predictive validity and may be useful to identify those with high self-efficacy who are more likely to achieve important healthbehaviour changes with pulmonary rehabilitation. The small effect size suggests thatthe PRAISE tool was not responsive to changes following pulmonary rehabilitation.
