AIMS: In this study we evaluated indicators of the feasibility, reliability, and validity of the Child Health Questionnaire-Child Form (CHQ-CF). We compared the results in a subgroup of adolescents who completed the standard paper version of the CHQ-CF with the results in another subgroup of adolescents who completed an internet version, i.e., an online, web-based CHQ-CF questionnaire. METHODS: Under supervision at school, 1,071 adolescents were randomized to complete the CHQ-CF and items on chronic conditions by a paper questionnaire or by an internet administered questionnaire. RESULTS: The participation rate was 87%; age range 13-17 years. The internet administration resulted in fewer missing answers. All but one multi-item scale showed internal consistency reliability (Cronbach’s alpha > 0.70). All scales clearly discriminated between adolescents with no, a few, or many self-reported chronic conditions. The paper administration resulted in statistically significant, higher scores on 4 of 10 CHQ-CF scales compared with the internet administration (P < 0.05), but Cohen's effect sizes d were
