PMID 37670757WHAT IT FOUND
A Japanese version of the Pain Understanding and Confidence Questionnaire was successfully adapted for physical therapists.
After two rounds of testing with 40 therapists each, all items were understood by at least 90% of respondents, allowing minor revisions and finalization.
Key findings
01The adaptation followed a five-stage process including forward and backward translation, with a pilot test requiring less than 10% of respondents to rate an item as 'not at all understandable' for acceptance.
02In the first pilot test, nine of 41 items received comments from more than 20% of respondents, necessitating a revised version and a second pilot test.
03In the second pilot test, no items received comments from more than 20% of respondents, and all items met the predetermined criteria for understanding.

What it does not show
The study used convenience sampling, which may not represent the broader population of physical therapists. Only physical therapists were included in the pilot tests, although the questionnaire is designed for use by other healthcare professionals. The adaptation process focused on understanding and translation quality, not on verifying the questionnaire's ability to predict patient outcomes or its psychometric properties in the Japanese context beyond internal consistency.
Declared interests
The authors declared no conflicts of interest and no funding.
The easy way to misread this
Do not assume this Japanese version has been proven to improve patient outcomes or predict clinical effectiveness. The study only confirms that the translated items were understood by therapists, not that the questionnaire accurately measures the impact of pain education on patient care.
