Respir. J. (2015)

Bottom Line: Our objective was item reduction and initial validation of two instruments to measure physical activity in COPD.Physical activity was assessed in a 6-week, randomised, two-way cross-over, multicentre study using PROactive draft questionnaires (daily and clinical visit versions) and two activity monitors.After item reduction, the daily PROactive instrument comprised nine items and the clinical visit contained 14.Confirmatory factor analysis supported the bidimensional structure.

Figure 2: Flowchart of the iterative process for the item reduction process.

Mentions: The item reduction process was conducted separately for each PROactive instrument and followed a systematic iterative process (fig. 2 and online supplementary material). Items were flagged and considered for removal if they exceeded prespecified thresholds of acceptability [18–25]. We hypothesised a priori that PROs alone might not capture information on the amount of physical activity well, so both item pools were analysed alone and in combination with activity data from each monitor (analysed separately).FIGURE 2
