Feasibility, reliability, and validity of adolescent health status measurement by the Child Health Questionnaire Child Form (CHQ-CF): internet administration compared with the standard paper version

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.
