Abstract
Aims: The aim of this study was to examine the test–retest reliability and concurrent validity of an adolescent single‐item physical activity measure by comparing it with the existing Oxford Physical Activity Questionnaire (OPAQ) and accelerometer output.
Methods: Participants were 123 adolescents (14.7 ± 0.5 years) from three secondary schools in New South Wales, Australia. To determine reliability, participants completed both questionnaires on two occasions separated by 2 weeks. To assess validity, participants wore Actigraph GT3X+ accelerometers for a 7‐day monitoring period and completed both physical activity questionnaires. Bivariate correlations between self‐reported moderate‐to‐vigorous physical activity (MVPA) and accelerometer MVPA min/day were calculated.
Results: The single‐item (intra‐class correlation coefficient (ICC) = 0.75, 95% confidence interval (CI) = 0.64–0.83, P < 0.001) ) and the OPAQ (ICC = 0.79, 95% CI = 0.69–0.86, P < 0.001) were both found to have moderate‐to‐strong reliability. Correlations between self‐reported and objectively measured MVPA were similar for the single‐item measure (r = 0.44, 95% CI = 0.24–0.63, P < 0.001) and the OPAQ (r = 0.50, 95% CI = 0.30–0.65, P < 0.001).
Conclusions: These findings suggest the single‐item measure can provide a reliable and valid assessment of youth physical activity.
