This study aims to evaluate the psychometric properties and sensitivity to change of the Spanish version of the Pain Level Outcome Scale.
This article applied observational longitudinal validation study with patients suffering from acute pain at three hospitals.
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.
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.
