Rasch Development and Validation of a New Faces Scale for Measuring Pain, and its Comparison with a Gold Standard: the Balparda–Herrera⟐ain Scale

Abstract

Aim: Faces pain scales are widely used to measure pain. So far, no faces pain scale has ever been constructed by Rasch modeling. Hence the authors aimed to construct a new scale by this method. Methods: Rasch modeling was used to provide an initial calibration and development of the ‘Balparda–Herrera Pain Scale’ (BHPS) and this scale was compared with the existing Faces Pain Scale – Revised. The scale was later refined. Results: Both the existing scale and the initial version of the BHPS required category collapsing. Statistical tests demonstrated an excellent concordance between both scales. The final version of the BHPS was found to behave excellently and to be capable of adequately measuring pain. Conclusion: The BHPS provides an excellent instrument for measuring pain in the adult population.

Chronic Pain Treatment and Digital Health Era-An Opinion

“…"Self-report" (29) is the primary way for pain measurement. There are various scales such as Verbal Rating Scales (VRS) (30), Numerical rating scales (NRS) (31), Visual Analog Scales (VAS) (32), Smiley-based Wong-Baker Scale (WBS) (33), Faces Pain Scales-Revised (FPS-R) (34) are used to get the selfreports from the chronic pain patients (35)(36)(37)(38). The second way of measuring pain is the "Observe behavior and infer" method (39).…”

Diseño, desarrollo y validación de un cuestionario para evaluar el compromiso visual y emocional en pacientes con queratocono

“…[163] La ventaja de los estudios desarrollados y calificados por medio del análisis de Rasch es que brindan un resultado con características de intervalo, [164] por lo que existe una relación lineal entre los distintos resultados, y, por ello, existe la posibilidad de realizar análisis estadísticos paramétricos convencionales. Nuevas escalas de dolor diseñadas recientemente por metodología Rasch, como la escala de dolor de Balparda-Herrera, [165] han pretendido solventar las limitaciones ordinales inherentes a la escala visual análoga.…”
