Self-Efficacy for Walking Scale - Duration (SEW_Dur)

The Self-Efficacy for Walking Scale - Duration is a measure to determine participants’ beliefs in their physical capability to successfully complete incremental 5-minute intervals (5 to 40 minutes) at a moderately fast pace. For each item, participants indicate their confidence to execute the behavior on a 100-point percentage scale comprised of 10-point increments, ranging from 0% (not at all confident) to 100% (highly confident). Total strength for each measure of self-efficacy is then calculated by summing the confidence ratings and dividing by the total number of items in the scale, resulting in a maximum possible efficacy score of 100.
