Hypothesis
The study aims to evaluate the reliability and validity of the Medical Outcomes Study Sleep Scale (MOS-Sleep) in patients with painful diabetic peripheral neuropathy.
Conclusion
The MOS-Sleep had good psychometric properties in this painful diabetic peripheral neuropathic population.
Supporting Evidence
- Cronbach's alpha ranged from 0.71 to 0.81 for the multi-item dimensions and the sleep problems index.
- Construct validity was supported with lower sleep adequacy scores associated with higher sleep problems index scores.
- Responsiveness was supported by effect sizes greater than 0.80 for patients who improved according to sleep interference and pain scores.
Takeaway
This study looked at how well a sleep questionnaire works for people with painful diabetes-related nerve damage, and it found that the questionnaire is reliable and valid.
Methodology
The study was a double-blind, randomized, placebo-controlled, multicenter, phase III clinical trial with 396 patients, assessing the psychometric properties of the MOS-Sleep Scale.
Limitations
The study did not evaluate test-retest reliability due to the design lasting 12 weeks, and the cross-cultural validity of the MOS-Sleep was not fully addressed.
