Valoración de la escala de dolor de caras-revisada (faces pain scale-revised) para evaluar la intensidad del dolor pediátrico en ni?os castellano parlantes

摘要

Objectives: The main objective of this study was to determine psychometric properties of the Spanish version of the Faces Pain Scale-Revised (FPS-R) as a measure of pain severity in Spanish-speaking children. Material and methods: In order to assess the validity and reliability of this scale, two independent samples were used. The first included 119 children and adolescents taken to the hospital due to different reasons. They were asked about their affective condition using the facial affective scale (FAS) and about the severity of their pain using the FPS-R and the coloured analogue scale (CAS). The second sample included 231 schoolchildren. In this case, they were asked to imagine eight hypothetical painful situations and to estimate pain severity associated to each of them using FPS-R and CAS. Results: In the group of subjects hospitalized, the reported pain severity was very similar, regardless whether or not they assessed pain through FPS-R or CAS, with correlation coefficients ranging from 0.82 to 0.91. The association between pain severity and affective condition of children was also statistically significant (r = 0.33, p < 0.01). In the schoolchildren group, the correlation coefficients ranged from 0.79 to 0.94. Test-retest reliability scores in the Painful Events Inventory were significant, ranging from 0.43 to 0.67. Conclusions: In general, this findings provide early evidences of the reliability and validity of convergence and criteria of the FDS-R. Moreover, our evidences suggest that, regardless the age and/or sex of the participants, they prefer the faces pain scale to the coloured analogue scale.
