The authors' objectives were to design, refine, validate and implement a behavior-anchored postburn pruritus scale for children aged 5 years or less. We engaged a range of professionals involved in the care of children with burns. We used Q-methodology in interprofessional team exercises to identify and stratify itch behaviors into categories of increasing severity, and then iteratively refined these into a draft scale. We used a range of quantitative and qualitative techniques to assess the utility, feasibility, and validity of the scale and refined it accordingly. During the implementation phase we collected some preliminary reliability data. We generated a 4-point scale of itch severity with simple descriptors of each score. We also designed a separate guidance note and example behaviors that could be used to orientate new users without the need for rater training. End-user interviews revealed high levels of feasibility and content validity. The reliability data showed moderate inter-observer agreement, with a Cohen's kappa of 0.52 (P < .001). We have developed and implemented a behavioral post-burn pruritus scale for use in children aged less than 5 years and have demonstrated its utility, feasibility, validity, and reliability. The development of a validated symptom scoring scales will allow for the conduct of high-quality quantitative clinical trials and the subsequent implementation of evidence-based management protocols.
