[Adapting and validating a questionnaire to measure the self-care practices in healthy child population residing in Spain].

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.
