Background:
Beliefs and attitudes about back pain are relevant factors in relation to developing back pain. A Danish version of the Back Pain Attitudes Questionnaire (Back-PAQ) could be a way of assuring a more systematic examination of attitudes about back pain within patients with back pain, laypeople and healthcare professionals in Denmark.
Objectives:
The aim of this study was to develop a Danish version of the Back-PAQ and assess its psychometric properties.
Study Design:
Study of diagnostic accuracy/assessment scale.
Method:
The adaptation was performed in several steps following the dual-panel method. The psychometric analyses included testing the reliability and validity.
Results:
Thirty-seven individuals participated in the translation process, and the main findings were that the translated version was considered to reflect the original version and that it was considered relevant to address beliefs related to back pain. Five hundred and thirteen patients were included in principal component analysis and sixty were included in the test-retest analysis. The analysis on the 10-item version revealed a structure that was similar to the original questionnaire and explained 82% of the variance in the dataset. The test-retest analysis showed an ICC of 0.80 (95% CI 0.67-0.88) and SDC ranged from 0.78 to 2.35 with a mean of 1.61.
Conclusion:
The Back-PAQ was successfully translated and cross-culturally adapted into Danish. Its psychometrics properties showed that the Danish version of the questionnaire is valid and reliable for assessment of beliefs and attitudes regarding back pain, and may prove useful in both clinical settings and research in Denmark.
