Spanish version of the Pain Vigilance and Awareness Questionnaire: psychometric properties in a sample of women with fibromyalgia.

Excessive attention to pain is a common psychological characteristic among people who suffer from chronic pain. The Pain Vigilance and Awareness Questionnaire (PVAQ) is an internationally accepted tool to assess this feature, although there is no validated version of this measure for Spanish people with fibromyalgia. Since this pain syndrome mainly affects women, the aim of this study was to determine the psychometric properties of the PVAQ in Spanish women with fibromyalgia. A group of 242 women diagnosed with fibromyalgia aged between 20 and 66 years participated in the study. The goodness of fit of several structures of the PVAQ reported in previous studies was compared via confirmatory factor analysis. A two-factor solution (active vigilance and passive awareness) of the 9-item shortened version (PVAQ-9) was identified as the most appropriate (RMSEA = .08, NNFI = .96, CFI = .97, GFI = .87). It showed good reliability (internal consistency α = .82), convergent validity and divergent validity (p < .01). The optimal cutoff point for identifying fibromyalgia women with worse daily functioning was a score of 24.5, with a sensitivity of .71 and a specificity of .75. The relevance of vigilance to pain for clinical research in fibromyalgia is discussed.
