Several questionnaires are available to evaluate illness perceptions in patients, such as the illness perception questionnaire revised (IPQ-R) and the brief version (Brief IPQ). This study aims to systematically review the literature concerning the clinimetric properties of the IPQ-R and the Brief IPQ in patients with musculoskeletal pain. The electronic databases Web of Sciences and Pubmed were searched. Studies were included when the clinimetric properties of the IPQ-R or Brief IPQ were assessed in adults with musculoskeletal pain. Methodological quality was determined using the COSMIN checklist. Eight articles were included and evaluated. The methodological quality was good for 3 COSMIN boxes, fair for 11 and poor for 3 boxes. None of the articles obtained an excellent methodological score. The results of this review suggest that the IPQ-R is a reliable questionnaire, except for illness coherence. Internal consistency is good, except for the causal domain. The IPQ-R has good construct validity, but the factor structure is unstable. Hence, the IPQ-R appears to be a useful instrument for assessing illness perceptions, but care must be taken when generalizing the results of adapted versions of the questionnaires. The Brief IPQ shows moderate overall test-retest reliability. No articles examining the validity of the Brief IPQ were found. Further research should therefore focus on the content and criterion validity of the IPQ-R and the clinimetric properties of the Brief IPQ. |
