The aim of the study was to evaluate the psychometric properties of the German translation of the Child Health Questionnaire (CHQ). Parents of two clinical samples were asked to rate the quality of life of their children using the German version of the CHQ. Item internal consistency (item-scale correlation) and internal consistency of scales were tested; quartiles and factor analysis were conducted. The results of the German clinical samples were compared with US clinical samples (t-test). The two clinical German sub-groups were compared using multivariate analysis (MANOVA). The psychometric testing of the CHQ showed good results. Internal consistency of the hypothesized scales were all higher than 0.70. The results of the factor analysis confirmed the results of the US norm sample: As expected, the subscales loaded on two factors explaining 57.4% of the total variance. The group comparison supported the discriminative properties of the CHQ. Preliminary psychometric findings support use of the German version of the CHQ. The next step will be the testing of healthy German samples and development of norm scores. [ABSTRACT FROM AUTHOR]
