HIGHLIGHTS
-
The Knowledge and Attitudes of Pain (KNAP) is a recently developed questionnaire for health care professionals.
-
KNAP is recommended during clinical or scientific pain knowledge research.
-
KNAP-Br has an appropriate measurement for use in Brazil, presenting reliability, internal consistency, and reproducibility.
ABSTRACT
BACKGROUND AND OBJECTIVES:
Health professionals attitudes and beliefs about musculoskeletal pain have a negative influence on patient beliefs and outcomes. However, there is no gold standard for assessing knowledge and attitudes toward pain among these professionals. Thus, the objective of the present study was to translate, adapt and validate the Knowledge and Attitudes of Pain (KNAP) questionnaire into Brazilian Portuguese (KNAP-Br), apply the questionnaire and analyze the correlation of its results with the Neurophysiological Pain Questionnaire (NPQ).
METHODS:
After being translated, back-translated and adapted, the NKAP-Br was applied to 60 physical therapy and medicine students for validation. The correlation between the results obtained by multiplying the scores of the questions of the NKAP-Br instrument and the NPQ was evaluated. To assess reliability, another 200 students responded to the initial KNAP-Br (T1), performed the Pain Education Program (PEP) in one week and one week after T1, the participants received access to answer the KNAP-Br end (T2).
RESULTS:
Concurrent validity was assessed by the correlation between NPQ and the final KNAP-Br score. A significant correlation was found between the NPQ result (0.3 and p-value=0.0001) and the KNAP-Br score. Intragroups, 84% improved in the KNAP-Br score after studying PEP, 43.50% improved at or above the minimal detectable difference (MDD) and at or above the minimal important difference (MID).
CONCLUSION:
The questionnaire was translated and adapted respecting the Brazilian population cultural aspects and presented satisfactory reliability and construct validity, being considered valid for the assessment of knowledge and the interpretation of pain by health professionals.
