摘要

Background

The KIDSCREEN is a transcultural and standardized instrument designed to assess health-related quality of life (HRQoL) in children and adolescents. Its shorter version, the KIDSCREEN-10 Index, has shown appropriate psychometric properties in various languages, but evidence supporting its validity and reliability in the Spanish version remains limited. The aim of the present study was to provide additional psychometric properties of the KIDSCREEN-10 Index in a representative sample of Spanish adolescents.

Methods

A stratified cluster random sampling method was used to select 2,235 students aged 12 to 18 years from schools in La Rioja, Spain, during 2022. Confirmatory factor analysis was conducted to examine the dimensional structure of the scores, and measurement invariance was tested across sex, age, socioeconomic status, sexual minority status, and nationality. Internal consistency was evaluated using McDonald’s omega and Cronbach’s alpha coefficients. Moreover, associations with emotional wellbeing and emotional and behavioural difficulties were examined.

Results

Confirmatory factor analysis revealed adequate goodness-of-fit indices for the unidimensional structure of the scores. Furthermore, measurement invariance was found across sex, age, socioeconomic status, nationality, and whether or not participants belonged to sexual minorities, allowing for the analysis of differences between subgroups. Females, older participants, those with lower socioeconomic status, foreign nationals, and participants belonging to sexual minorities scored significantly lower than their respective comparison groups. Moreover, a three-way interaction between sex, age, and sexual minority status was found indicating possible intersectional effects. High internal consistency of the KIDSCREEN-10 Index scores was also observed (Ω = 0.874; α = 0.872). A significant positive correlation was found between the KIDSCREEN-10 Index score and emotional wellbeing, while a significant negative correlation was observed with emotional and behavioural difficulties.

Conclusions

The Spanish version of the KIDSCREEN-10 Index showed adequate psychometric properties, supporting its potential as a reliable and valid tool to measure the HRQoL in adolescents.
