OBJECTIVE To adapt and validate the Child and Adolescent Self-Care Performance Questionnaire (CASPQ) to the context of healthy children aged 8 to 12years residing in Spain and evaluate their metric properties. DESIGN Validation study based on Classical Test Theory. LOCATION Four schools participating in the Salut i Escola programme of a Primary Care Centre of Barcelona (Spain). PARTICIPANTS Four hundred and ninety-eight elementary school students participated in the study during the first six months of 2016. MAIN MEASUREMENTS Cultural adaptation of the questionnaire was carried out. Response process and factorial structure were evaluated and the relationships of the adapted questionnaire scores with those of the KIDSCREEN-27 questionnaire were analysed. Likewise, internal consistency and reproducibility of the scores were evaluated. RESULTS Four hundred and eighty-nine questionnaires were obtained. The confirmatory factor analysis of its theoretical structure showed a sufficient adjustment. A positive association was observed between the questionnaire scores and those of KIDSCREEN-27. The overall internal consistency was satisfactory; nevertheless, that of each factor was marginal or moderate. The reproducibility of the scores was optimal. CONCLUSIONS The CASPQ adapted to the healthy child population of 8 to 12years old shows appropriate metric properties and similar to those of the original questionnaire. Therefore, it is a useful tool to assess self-care practices and plan interventions aimed at its promotion.
