The Adaptation and Psychometric Properties of the Kid-KINDLR for Hospitalized Children in Chile

Abstract Purpose The impact of hospitalization on a child's well-being leads one to consider the health-related quality of life (HRQoL) measure as a fundamental aspect of pediatric care. The aims of the study were to adapt the Spanish version of the Kid-KINDL® to hospitalized children in Chile, to obtain a reduced version of the instrument and to analyze the psychometric properties of the reduced version. Design and Methods An expert committee and interviews were carried out for the cross-cultural adaptation process. An exploratory factor analysis was conducted to examine the validity of the construct and to select the items for the reduced version. Cronbach’s alpha was used to estimate the internal consistency of the adapted version of the Kid-KINDL® and the reliability of each component. Convergent validity was based on correlations with a pain scale. Results This adapted and shorter instrument, similar to the original version, comprises five components that include the principal dimensions of HRQoL. Evaluating the School dimension in hospitalized children was considered inappropriate in Chilean public hospitals. The study replicates the relationship found between a child with high pain and low reported HRQoL. Conclusions The hospitalization process impacted the children’s perceptions of their HRQoL. The reduced version of the Kid-KINDL® was found to be a valid instrument for assessing children’s HRQoL in hospital units. Practice Implications: Finding effective ways to measure HRQoL and ultimately mitigate barriers and foster resilience are important clinical and research priorities in the pursuit of HRQoL for hospitalized children and their families.
