Hypothesis
The factor structure of the Shoulder Pain and Disability Index (SPADI) will support the separation of scores into distinct pain and disability subscales in patients with adhesive capsulitis.
Conclusion
The study found minimal evidence to justify the use of separate subscales for pain and disability in the SPADI for patients with adhesive capsulitis.
Supporting Evidence
- The study involved 191 patients with adhesive capsulitis who completed the SPADI questionnaire.
- Two factors were extracted from the analysis, but they did not clearly separate pain and disability items.
- Internal consistency of the SPADI was found to be high, with a Cronbach alpha of 0.90 for the total score.
Takeaway
This study looked at a questionnaire for shoulder pain and found that it doesn't really separate pain from disability; they are more connected than we thought.
Methodology
The study used a cross-sectional design, administering the SPADI questionnaire to 191 patients and analyzing the data with descriptive statistics and factor analysis.
Limitations
The factor structure did not support the original division of the SPADI, indicating potential issues with the questionnaire's design for this patient group.
Participant Demographics
Mean age was 51.9 years, with 58% female participants.
