Aim: This study was carried out to adapt a measurement tool that can be used to measure the perceived satisfaction level of parents of pediatric patients hospitalized in a pediatric clinic with care from pediatric nurses and to examine its psychometric properties. Design and method: The study was conducted methodologically with 301 parents of children who were hospitalized in the pediatric clinic of a university hospital between September and December 2023. Explanatory and confirmatory factor analyses were performed on the data to establish the validity of the scale, Cronbach's alpha reliability coefficient, split-half, item-total score methods were utilized to test its reliability. Results: The scale consisted of 26 items and a single dimension. It was determined that the total explained variance ratio was 79.246%. According to the confirmatory factor analysis results, goodness of fit values were determined as RMSEA = 0.077, CFI = 0.96, IFI = 0.97, RFI = 0.92, NFI = 0.93, and TLI = 0.96. Cronbach's alpha coefficient was calculated as α = 0.989 for the total scale. Conclusion: The Parents' Perception of Satisfaction with Care from Pediatric Nurse Practitioners Instrument is a valid and reliable measurement tool that can be used to measure the perceived satisfaction level of parents of pediatric patients hospitalized in a pediatric clinic with nursing care. Implications for practice: The scale can contribute to determining the perceived satisfaction levels of parents of pediatric patients hospitalized in the pediatric clinic with nursing care and, if there is a problem, to providing regular in-service training for pediatric nurses who are responsible for pediatric patient safety and quality of care.
