Adherence to clinic-based rehabilitation might influence outcomes.
To examine the construct validity and interrater agreement of a measure of adherence to clinic-based rehabilitation.
Repeated-measures in both study 1 and study 2.
43 student rehabilitation practitioners in study 1 and 12 patients undergoing rehabilitation after anterior cruciate ligament reconstruction in study 2.
Participants in study 1 rated the adherence of a simulated videotaped patient exhibiting high, moderate, and low adherence. Two certified athletic trainers rated the adherence of patients at 4 consecutive appointments in study 2.
Main Outcome Measure:
The Sport Injury Rehabilitation Adherence Scale.
In study 1, adherence ratings increased in a linear fashion across the 3 levels of adherence, and
rWG(J)and rater-agreement-index values ranging from .84 to .95 were obtained. In study 2, the rater-agreement index was .94. Conclusions:
Strong support was found for the construct validity and interrater agreement of the Sport Injury Rehabilitation Adherence Scale.
