Reproducibility and Validity of an Epidemiologic Questionnaire to Assess Past Year Physical Activity in Adolescents

The reproducibility and validity of a past year physical activity questionnaire was determined in a sample of 100 adolescents aged 15–18 years, randomly selected from a population-based cohort. Subjects completed four 7-day recalls of activity approximately 3 months apart. The average of the four 7-...

Description
Summary:The reproducibility and validity of a past year physical activity questionnaire was determined in a sample of 100 adolescents aged 15–18 years, randomly selected from a population-based cohort. Subjects completed four 7-day recalls of activity approximately 3 months apart. The average of the four 7-day recalls of activity was utilized as the “gold standard”against which the past year questionnaire was compared to evaluate validity. The questionnaire was also validated against objective measures, such as physical fitness and body mass index. Interscholastic team rosters were utilized to directly validate the reporting of specific activities. One-month and one-year test-retest reproducibility of the questionnaire were determined. For different measures of activity, the Spearman correlations between the questionnaire and the average of the 7-day recalls ranged from 0.55 to 0.67 in males and 0.73 to 0.83 in females, all significant at p
