Barriers Self-Efficacy Scale (BARSE)
The Barriers Specific Self-Efficacy Scale was designed to tap subjects' perceived capabilities to exercise three times per week for 40 minutes over the next two months in the face of commonly identified barriers to participation. 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.
