Fiabilidad de un cuestionario de modos, tiempo y distancia de desplazamiento en estudiantes universitarios

Introduction: Active commuting is an opportunity to incorporate physical activity in the daily routines of university students, so to achieve physical activity recommendations and help preventing diseases in adult life. Objective: to verify the reliability of a questionnaire about active commuting in university students. Methods: a total of 110 university students (33 women and 77 men) aged between 19 and 26 years old participated in this study. Participants completed a questionnaire on how they commute to the university and commuting variants in two separated measurement sessions (test and retest). In order to evaluate the reliability of this questionnaire, Kappa coefficient and Intraclass Correlation Coefficient (ICC) were calculated using SPSS statistical software. Results: ê scores for commuting to and from university were found in almost perfect agreement, with values of 0.882 and 0.822 respectively. ICC scores on distance to and from university were 0.945 and 0.962 respectively; and for time to and from university they were 0.976 and 0.976 respectively, the values being in almost perfect agreement based on the interval. Conclusion: The questionnaire shows to be a reliable instrument for the university population, showing good reliability in all its items, with high ê and ICC values. The lack of significant p values reinforces the high reliability of the questionnaire.
