Reliability by surgical status of self-reported outcomes in patients who have shoulder pathologies.

Study Design: A test-retest design was used to evaluate the reliability of the self-report sections of 4 shoulder pain and disability scales.

Objective: The objective of the study was to compare interitem consistency and test-retest reliability by surgical status (postoperative versus nonoperative) and to evaluate the effect of surgical status in the prediction of retest scores.

Background: Patients and healthcare providers evaluate shoulder status based on self-evaluations of pain and disability.
