Fiabilidad de la versión española del Cuestionario de actividad física PAQ-C / Reliability of the Spanish Version of Questionnaire of Physical Activity PAQ-C

Abstract

Objective. This research aimed to assess the reliability of the Physical Activity Questionnaire in Spanish children (PAQ-C). Method. The recognised Spanish translation version of the Physical Activity Questionnaire for Adolescents (PAQ-A) was used as reference. In a sample of 72 children aged between 8 and 14 years, the test-retest reliability of the PAQ-C was analysed in three measurements: before the Physical Education class (M1), two hours later (M2) and one week later (M3). The reliability was determined by means of the Intraclass Correlation Coefficient (ICC) and the inner consistency through Cronbach’s α coefficient. Results. The results obtained in the overall score of the questionnaire reflect an intraclass coefficient (ICC) higher than 0,73 in every possible comparison giving a confidence interval of 95% which still indicates a good or very good reliability. The inner consistency showed a coefficient of α = 0,83.
