A total of 111 paediatric surgery patients aged between 2 and 12 years and 1 parent of each study subject were included. After surgery, each child's level of pain was assessed, and each parent completed the Spanish PPPM scale.
The PPPM items in Spanish showed good internal consistency (Cronbach's alpha between 0.784 and 0.900) and scores were closely related to the global pain assessment (Spearman's rho correlation between 0.626 and 0.431). The score decreased from the day of surgery to the first postoperative day, and the scale was successful in discriminating between children who had undergone mild, moderate and severe pain surgeries.
We conclude that the Spanish version of the PPPM scale evaluated in this study is a suitable tool for assessing paediatric postoperative pain in the home.
