Abstract:
Sleep disturbances caused by painful diabetic neuropathy ( PDN ) might have substantial impacts on the multifaceted aspects of PDN , including quality of life. There are no convincing data on the validation or reliability of sleep problem measurements in patients with PDN in K orea. This large population‐based cross‐sectional study examined psychometric properties of the M edical O utcomes S tudy ( MOS ) Sleep S cale in patients with PDN in K orea. Materials and Methods Measurements of patient‐reported outcomes ( B rief P ain I nventory‐short form, MOS S leep S cale and E uro Q o L Health [ EQ ‐5D]) were documented. PDN was diagnosed if the average daily pain intensity was ≥4 based on the visual analog scale or if patients were taking medication for their current pain. Results There were 577 patients with PDN (41.6% with diabetic peripheral neuropathy). The internal consistency of reliability for the MOS Sleep Scale was 0.80 as measured by C ronbach's alpha. The extent to which multiple items in a dimension were intercorrelated and formed a dimension measuring the same underlying concept ( P earson's correlation coefficient) ranged from 0.24 to 0.71 (all P 〈 0.001). Each item of the MOS S leep S cale was significantly correlated with the average pain score and the pain interference score ( P earson's correlation coefficients ranged from 0.20 to 0.28 and from 0.29 to 0.40, respectively; all P 〈 0.001). The correlations between the EQ ‐5 D index and the MOS Sleep Scale ranged from −0.27 to −0.31 (all P 〈 0.001). Conclusions The MOS S leep S cale showed good reliability in the evaluation of PDN in K orean type 2 diabetic patients.
