Purpose: This study was performed to develop a scale of nurse’ pain knowledge and examine the appropriateness verification using item response theory.
Method: Validity of developed 25 items were screened by 9 expert panels, and then 22 items were judged as high valid. After do preliminary investigation, difficult items were corrected. The subject were 764 nurses chosen from 7 hospitals. Analysis of data were used BayesAN 1.0 and SPSS.
Result: The item with the highest of item difficulty was ’patients can sleep in spite of moderate or severe pain’, and the item with the highest of item discrimination was ’increase of tolerance for opioid means poisoning.’. Whereas the item with the lowest of item difficulty and item discrimination was ’opioids act on the central nervous system to decrease the perception of pain, whereas nonopioid act on the peripheral nervous system to decrease the transmission of pain impulses’. The discrimination is suitable, but difficulty is easy. The range of pain knowledge total-scores were from 6 to 21, whereas true-scores were from 9 to 18.
Conclusion: We need to do repeat research after correcting item difficulty, and propose to apply a item response theory for appropriateness verification of a scale in nursing.
