Diseño y validación de una escala para medir en profesores de Educación Física el uso responsable de las pruebas de condición física (FITPET) (Design and validation of a scale to assess the responsible use of fitness testing in physical education teachers (FITPET))

El presente estudio tuvo como objetivo disenar y validar una escala para evaluar en profesores de Educacion Fisica el uso responsable de las pruebas de condicion fisica relacionadas con la salud. Metodo: participaron un total de 374 docentes de secundaria (266 hombres y 108 mujeres) de centros educativos pertenecientes a las ocho provincias andaluzas, con edades comprendidas entre 24 y 67 anos (41.92 ± 9.24 anos). Resultados: en primer lugar, se diseno un instrumento de 26 items, que obtuvo valores de correlacion item-total ≥ .35, exceptuando 5 items. Posteriormente, se evaluo la estructura interna de la escala, resultando esta pertinente. El analisis estadistico de los items y el posterior analisis factorial exploratorio dio como resultado cinco factores (orientacion del resultado, uso de estilos participativos, el enfoque educativo, rigor metodologico y refuerzo positivo), con correlaciones positivas y significativas, constatadas mediante analisis factorial confirmatorio, pruebas de invarianza factorial, asi como de fiabilidad y validez convergente y discriminante. Los resultados del analisis de propiedades psicometricas de la escala fueron adecuados y permitieron ofrecer un instrumento ad hoc de 15 items, con moderados valores de validez y fiabilidad, acreditando su utilidad para valorar en profesores de Educacion Fisica el uso responsable de las pruebas de condicion fisica en sus clases.===The aim of this study was to design and validate a scale that would allow the evaluation in Physical Education teachers the responsible use of physical fitness tests related to health. Method: The sample was composed of 374 secondary school teachers (266 men and 108 women), from educational centers belonging to the eight Andalusian provinces, aged between 24 and 67 years (41.92 ± 9.24). Results: Firstly, a 26-item instrument was designed, which obtained item-total correlation values of ≥ .35, except for 5 items. Then, the internal structure of the scale was evaluated and proved to be relevant. The statistical analysis of the items and the subsequent exploratory factor analysis resulted in five factors (orientation of the result, use of participatory styles, the educational approach, methodological rigor, and positive reinforcement), with positive and significant correlations, confirmed by confirmatory factor analysis, factor invariance tests, as well as reliability and convergent and discriminant validity and reliability. The results of the analysis of psychometric properties of the scale were moderate and allowed us to offer a valid and reliable 15-item an ad hoc instrument, with adequate values of validity and reliability, proving its usefulness the evaluation in Physical Education teachers the responsible use of physical fitness tests in their classes.
