Abstract
Introduction: The LIVAS questionnaire aims to capture patient’s beliefs in physical ability, which is a possible determinant of physical activity.
Aim: We investigated the relationship between patient’s beliefs in physical ability and objectively measured physical functioning.
Methods: In this observational analysis, 34 patients with COPD (68±8 years, 65% male, FEV1 59±18 %pred, 6MWD 491±88 m, 6316±3534 steps/day) were included. Mean steps/day (Dynaport MoveMonitor), exercise capacity (6-minute walk distance (6MWD)) and lung function were measured. Self-efficacy with respect to physical ability was investigated by LIVAS, including 10 items on a 5-point Likert scale, with a higher score indicating better self-efficacy. Spearman correlation was used to relate LIVAS score and physical functioning.
Results: Median (IQR) LIVAS total score was 25 (6) points. Walking stairs and walking speed was by most indicated as ‘worse’ or ‘much worse’ as compared to peers (resp. 85%, 79%), see fig 1. In general, beliefs in physical ability had a moderate correlation with residual volume %pred (r= -0.42; p<0.05) and 6MWD (r= 0.44; p<0.05), but not with steps/day (r= 0.01; p =0.95) or FEV1%pred (r=0.22; p=0.21). Of note, LIVAS was not related to gender but tended to be higher with increasing age (p=0.08).
Conclusion: Self-efficacy regarding physical ability correlates with hyperinflation and exercise capacity, but not with steps per day or airflow obstruction.
