“…In essence, the results described here are consistent with several previous studies, especially with instruments that measure physical activity and fitness [15][16][17] , and with instruments that were constructed to assess eating habits 18,19 and attitude toward obesity in adolescent girls 20 ; therefore, including the explanatory percentage of the study variance, which explained 70.8% of the variance, this is a clear indication that the confirmatory factor analysis allowed to contrast the substantive theories of the PA questionnaire, although the development of new studies is necessary, including samples of adolescents from other regions of Chile, as this information could help confirm these findings, and thus achieve external validity.…”

En relación con la fiabilidad del instrumento, el estudio consideró el análisis de consistencia interna.…”

Además otros estudios que investigaron la validez de constructo en temáticas relacionadas al presente estudio, reportaron valores de varianza y cargas factoriales similares y hasta inferiores al presente estudio (15)(16)(17).…”
