Health-promoting behaviors: psychometric properties of an assessment tool

Comportamientos promotores de la salud: propiedades psicométricas de un instrumento de evaluación

Authorship SCIMAGO INSTITUTIONS RANKINGS

Aiming to evaluate the psychometric properties of an instrument to assess the levels of health promoting behaviors, as well as to encounter those same levels related to their age, sex and graduation in a sample of 1213 Portuguese adolescents, the study was conducted of a quantitative, descriptive, correlational, retrospective and cross-sectional. The instrument has good internal consistency (Cronbach's Alpha de 0,889) and reasonable correlations between items (entre -0,009 e 0,788), confirming the six factors defined by the authors of the scale. Levels of health-promoting behaviors in the sample are good (x=3,70), being higher in girls than boys, and youth to the detriment of younger older. Thus demonstrates the reliability of the instrument in the assessment of healthy behavior in portuguese adolescents, as well as the need for an health intervention in this population.
