Within the self-perception/self-concept questionnaires, theRosenberg Self-Esteem Scale stands out for being an optimal and widely used resource in adolescents.Regarding the questionnaires that evaluate self-perception, the General Health Questionnaire is themost used; it is used in numerous national health surveys in different countries. The Physical ActivityQuestionnaire for Adolescents ranks first with respect to the rest of the tools. It is a widely used resourceinternationally and provides enough information on the physical activity carried out by the subject in agiven week. Although there are several questionnaires that measure lifestyle, the Health Behavior inSchool-aged Children instrument was selected.
