Cultural Adaptation and Validation of the painDETECT Scale Into Spanish

Abstract

The culturally adapted version of the painDETECT presents good psychometric properties and shows to be a valid patient-reported outcome for measuring the presence of a neuropathic component in patients with chronic pain.

Measurement properties of painDETECT by average pain severity

“…However, the seven-item version resulted in a slightly higher reliability (Cronbach’s α =0.80) than the nine-item version (Cronbach’s α =0.76) and more consistent item-level discrimination. The reliability of the seven-item version is not only similar to that reported in the validation study (Cronbach’s α =0.83),15 but its higher value than the nine-item version is also in concordance with previous observations,27 suggesting that the two nonsensory items are not psychometrically compatible with the sensory items. While further confirmation for the greater reliability of the seven-item version is needed, it can nevertheless be recommended that the seven sensory items be used together; the two nonsensory items, on temporal and spatial characterization of the pain pattern, that are included in the nine-item version can be analyzed and interpreted separately.…”

“…Although there is a need for characterizing and quantifying NeP concurrently with its identification in patients with various NeP conditions, to our knowledge, no other NeP instrument has yet been specifically validated for distinguishing between levels of average pain severity. These results therefore complement and extend studies that have suggested that NeP-screening instruments may help distinguish among sensory symptom profiles and pain-severity levels 16,17,25–27…”

“…In addition, in the current study, the cumulative distributions convincingly showed that painDETECT scores were dependent on the degree of average pain severity for patients with confirmed NeP; fitting only one curve for all patients with NeP (ie, without regard to average pain severity), as has been done previously,15,27 would mask this finding.…”

“…It should also be noted that since the population in the current study consisted of patients with confirmed NeP, the cumulative distribution curves are in marked contrast to those in studies evaluating discrimination between main pain subtypes (nociceptive, pure neuropathic, mixed) where the nociceptive group clearly resulted in lower (more favorable) scores on painDETECT 15,27. In addition, in the current study, the cumulative distributions convincingly showed that painDETECT scores were dependent on the degree of average pain severity for patients with confirmed NeP; fitting only one curve for all patients with NeP (ie, without regard to average pain severity), as has been done previously,15,27 would mask this finding.…”
