Self-reported health-related quality of life in kindergarten children: psychometric properties of the Kiddy-KINDL.

To assess the psychometric properties of the German self-reported version of the Kiddy-KINDL that measures Health Related Quality of Life (HRQoL) in 3 to 5 year old kindergarten children. The population of the study comprised baseline data of a longitudinal study whose main aim is to investigate self-reported health outcomes in young children (N = 317). Missing values, the distribution of data, internal consistency (Cronbach's alpha and Guttman's lambda), and reliability (split half and two weeks test-retest) were analysed. To assess discriminant validity, mean differences were tested splitting the sample regarding socio-emotional competences (VBV 3-6), age and gender. Structural validity was investigated with Confirmatory Factor Analysis (CFA). Mean HRQoL was 69.79 (SD 16.84). Overall missing values were 8.1%, overall Cronbach's alpha was 0.75 and overall Guttman's lambda was 0.77; for the whole scale Spearman-Brown test for split half reliability resulted in 0.80 and ICC for test-retest in 0.83. Discriminant validity investigation differentiated groups with high and low socio-emotional competence and those children who were 4.5 years or older, compared to the younger ones. Differences between boys and girls were also found. CFA suggested two main dimensions: physical and socio-emotional. This preliminary validation of the Kiddy-KINDL in very young children shows satisfactory psychometric properties. However, results of the Cronbach's alpha, Guttman's lambda and the CFA depicted problems, mainly in the psychological dimension. Due to these we recommend to use the Kiddy-KINDL as an instrument with only two dimensions. Further studies in general population samples are needed.

[Parent-reported Health-Related Quality of Life in Spanish pre-schoolers: Psychometric properties of the Kiddy-KINDL-R].

Although several tools have been developed to assess general HRQoL in children, parental reports are required to supplement this information, especially in very young children. The parents version of the 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 parents version of the Kiddy-KINDL-R questionnaire and assess its psychometric properties in a sample of Spanish preschool-aged children. Cross-sectional study in 283 parents or legal guardians of children aged 3 to 6 years that completed the Kiddy-KINDL-R questionnaire and an additional scale to assess anxiety problems. We performed confirmatory factor analysis to assess whether the original Kiddy-KINDL-R version fit the Spanish data; we assessed internal consistency by means of the ordinal alpha and the discriminant validity by means of the Preschool Anxiety Scale. Although the original six-factor model showed a good fit, we propose a model consisting of 22 items and the same 6 factors for the Spanish version. The reliability was excellent, and the internal consistency values were adequate. Our results showed significant negative correlations between the Kiddy-KINDL-R and the external anxiety measure, which was evidence of discriminant validity. We demonstrated that the Spanish version of the Kiddy-KINDL-R had good psychometric properties and that this questionnaire is an adequate assessment tool that could be useful in clinical practice.
