Abstract

Purpose: This study aims to evaluate the psychometric properties and sensitivity to change of the Spanish version of the Pain Level Outcome Scale.

Methods: This article applied observational longitudinal validation study with patients suffering from acute pain at three hospitals.

Findings: The study included 73 patients. Inter-rater agreement was kappa = .88 and internal consistency α = .93. Principal components analysis yielded four components that explained 81.86% of the variance; the correlation with the Numerical Pain Intensity Scale was r = -.81.

Conclusions: The version with 17 indicators shows good psychometric properties and adequate sensitivity to change. A Spanish version of the Pain Level Outcome Scale with 17 indicators is proposed as a structured multidimensional instrument to help nurses choose the most appropriate indicators for assessing patients' pain.

Keywords: Acute pain; Nursing Outcomes Classification (NOC); validation study.
