Development of a Shoulder Pain and Disability Index

Abstract

A shoulder pain and disability index (SPADI) was developed to measure the pain and disability associated with shoulder pathology. The SPADI is a self‐administered index consisting of 13 items divided into two subscales: pain and disability. Thirty‐seven male patients with shoulder pain were used in a study to examine the measurement characteristics of the SPADI. Test‐retest reliability of the SPADI total and subscale scores ranged from 0.6377 to 0.6552. Internal consistency ranged from 0.8604 to 0.9507. SPADI total and subscale scores were highly negatively correlated with shoulder range of motion (ROM) supporting the criterion validity of the index. Principal components factor analysis with and without varimax rotation supported the construct validity of the total SPADI and its subscales. High negative correlations between changes in SPADI scores and changes in shoulder ROM indicated the SPADI delected changes in clinical status over short time intervals. The SPADI should prove useful for both clinical and research purposes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
