Psychometric evaluation of the Pain Vigilance and Awareness Questionnaire (PVAQ) in fibromyalgia: Confirmatory factor analysis and the development of a Swedish 8 ‐item version

ConclusionsThe Swedish PVAQ-9 and PVAQ-8 appear to have acceptable psychometric properties when administered online to individuals with fibromyalgia. The PVAQ-8 may be preferable due to being shorter and including an equal number of items per factor. Replication is warranted.SignificanceThis study evaluated the psychometric properties of a Swedish translation of the PVAQ in individuals with fibromyalgia. No convincing factor structure was found for the 16-item version. We could, however, confirm the factor structure of an established 9-item version (the PVAQ-9), and recommend further use of a new 8-item version (the PVAQ-8). In summary, the PVAQ exhibited more convincing psychometric properties when the number of items was roughly cut in half.
