Results: For the older age group, significant correlations between the instruments were
found for time spent walking, for moderate and vigorous activities as well as for total physical
activity (Rs= 0.17–0.30, P< 0.05). No significant correlations were found for any of the
variables studied in the younger age group. Kendall's tau-b showed low but significant
correlations for tertiles of total physical activity (P< 0.001). Conclusions: The IPAQ-A has

Results:
For the older age group, significant correlations between the instruments were found for time spent walking, for moderate and vigorous activities as well as for total physical activity (Rs= 0.17–0.30, P< 0.05). No significant correlations were found for any of the variables studied in the younger age group. Kendall's tau-b showed low but significant correlations for tertiles of total physical activity (P< 0.001).
Conclusions:
The IPAQ-A has reasonable validity properties for assessing activities in different intensities and for total physical activity in healthy European adolescents aged 15–17 years. For adolescents aged 14 years and younger, the correlations were unsatisfactorily low and objective methodology, such as accelerometry, may be the appropriate alternative.
