Abstract

Background: There are many methods available for measuring social support and quality of life (QoL) of adolescents, of these, the KIDSCREEN tools are most widely used. Thus, we aimed to translate and validate the KIDSCREEN-27 scale for the usage among adolescents aged between 10 and 19 years old in Slovenia. Methods: A cross-sectional study was conducted among 2852 adolescents in primary and secondary school from November 2019 to January 2020 in Slovenia. 6-steps method of validation was used to test psychometric properties of the KIDSCREEN-27 scale. We checked descriptive statistics, performed a Mokken scale analysis, parametric item response theory, factor analysis, classical test theory and total (sub)scale scores. Results: All five subscales of the KIDSCREEN-27 formed a unidimensional scale with good homogeneity and reliability. The confirmatory factor analysis showed poor fit in user model versus baseline model metrics (CFI = 0.847; TLI = 0.862) and good fit in root mean square error (RMSEA = 0.072; p(χ 2) < 0.001). A scale reliability was calculated using Cronbach's α (0.93), beta (0.86), G6 (0.95) and omega (0.93). Conclusions: The questionnaire showed average psychometric properties and can be used among adolescents in Slovenia to find out about their quality of life. Further research is needed to explore why fit in user model metrics is poor.

Bibliographical note

Funding Information:
The KIDSCREEN questionnaire is available in three versions; the original long version consists of 52 items covering ten dimensions of QoL, a 27-item version covering 5 dimensions of QoL, and a 10-item index version []. The KIDSCREEN-27 measures five Rasch scaled dimensions: 1) physical well-being, 2) psychological well-being, 3) autonomy and parent relation, 4) peers and social support, and 5) school environments. The questionnaire was funded by the European Commission and developed within a European project "Screening and Promotion for Health-related Quality of Life in Children and Adolescents—A European Public Health Perspective" [–]. Each item was scored on a 5-point Likert scale ranging from 1 meaning "not at all" to 5 meaning "very much". Certain items (1, 9, 10 and 11) were reversed when scoring the questionnaire. Reverse scoring means that the numerical scoring scale runs in the opposite direction. The total KIDSCREEN score was calculated by summing up all the responses. Higher scores of KIDSCREEN indicated better QoL and social support. Before using the questionnaire, the prior permission to use was sought from the authors.
