Although there are different measures to evaluate the overall HRQoL in children, parental reports are required to supplement this information, especially in very young children. The parent version of Kiddy-KINDL-R was developed to assess HRQoL in children aged 3 to 7 years through the reports of their parents or legal guardians. The aim of this study was to validate the parent version of the Kiddy-KINDL-R questionnaire and assess its psychometric properties in a sample of Spanish preschool-aged children. The results showed excellent reliability and discriminant validity with a measure of anxiety. The Spanish version of Kiddy-KINDL-R demonstrated good psychometric properties and is also a suitable and useful assessment tool in clinical practice. You can consult the study here.
