Abstract
Background: To date, no studies exist that have utilized theoretical correlates to explain steps / day during and after pulmonary rehabilitation (PR), which has been a noted limitation in a recent meta-analysis conducted by our group. The purpose of the present study was to determine whether barrier self-efficacy (BSE), task self-efficacy (TSE), and / or outcome expectations (OE) were significantly associated with steps / day during and after PR. Methods: 194 patients (mean age = 66.15; 54% male) wore a pedometer for 7 days, recorded their daily steps in a log book, and completed a social ecological survey at the beginning, end, 3, and 9 months after completing PR. Results: Separate linear growth models were conducted in MPlus 7.0 using BSE, TSE, and OE’s as time varying covariates to examine their association with steps / day controlling for age and gender. Results showed that neither BSE nor TSE were significantly associated with steps / day during or after PR. However, baseline OE was significantly associated with end of PR steps / day (beta = 404.71, p = .01), end of PR OE was significantly associated with steps / day 3 months after PR (beta = 757.21, p = .02), and 3 month OE was significantly associated with steps / day 9 months after PR (beta = 1224.26, p = .01). Conclusions: OEs appear to be a key steps / day correlate that should be used to inform a steps/ day intervention during and after PR.Acknowledgments: Social Sciences and Humaniteis Research Council of Canada
