Hypothesis

To determine the clinimetric properties of two questionnaires assessing symptoms and physical functioning in a Dutch primary care population.

Conclusion

The Symptom Severity Scale is suitable for assessing symptom severity, while the Dutch-AIMS2-HFF is less suitable for measuring physical functioning in patients with hand and wrist problems.

Supporting Evidence

  • The Symptom Severity Scale had an ICC of 0.68, indicating moderate reliability.
  • The Dutch-AIMS2-HFF had an ICC of 0.62, indicating moderate reliability.
  • The smallest detectable change for the Symptom Severity Scale was 1.00 at individual level.
  • The smallest detectable change for the Dutch-AIMS2-HFF was 3.80 at individual level.
  • The minimal important change for the Symptom Severity Scale was 0.23.
  • The minimal important change for the Dutch-AIMS2-HFF was 0.31.
  • 30% of patients showed a floor effect on the Dutch-AIMS2-HFF.

Takeaway

This study looked at two questionnaires to see how well they measure symptoms and function in people with hand and wrist issues. One worked well, but the other didn't.

Methodology

Participants completed the questionnaires twice within 1 to 2 weeks, and data were analyzed for reliability and responsiveness.

Limitations

The Dutch-AIMS2-HFF showed a floor effect, limiting its ability to detect changes in patients with minimal symptoms.
