IntroductionAssessment of postoperative pain is a fundamental aspect of post-surgical care. When surgery is performed as an outpatient, the parents are mainly responsible for the assessment of pain, but they may not always correctly evaluate their children's pain. This makes it necessary to have tools that help them to assess postoperative pain reliably. The Parent's Postoperative Pain Measurement (PPPM) is a behavioral measurement tool of post-operative pain developed to help parents to assess their children's post-operative pain. The purpose of this work was to translate this scale into Spanish, and validate the psychometric properties of the Spanish version of the scale.MethodParticipants were 111 children aged 2 to 12 years, who had undergone surgery, and one of their parents. After the operation, the children's level of pain was assessed, and the parents completed the PPPM scale in Spanish.ResultsThe PPPM items in Spanish showed good internal consistency (Cronbach alpha between 0.784 and 0.900) and the scale scores were closely related to the global pain assessment (Spearman's rho correlation between 0.626 and 0.431). The score on the scale decreased between the day of the operation and the next day, and discriminated well between children undergoing surgery qualified as low/moderate pain and high pain.ConclusionsWe conclude that the Spanish version of the PPPM scale evaluated in this study, has good psychometric properties to assess postoperative pain by parents at home.Copyright © 2015 Asociación Española de Pediatría.
