Spearman correlation and ICC between accelerometer-measured and self-reported time spent in each movement behavior.

^aSpearman correlation coefficients (r) were interpreted as poor (≤0.29), moderate (0.30-0.39), strong (0.40-0.69), or very strong (≥0.70) correlations.

^bICC: intraclass correlation coefficient.

^cICCs were interpreted as poor (<0.50), moderate (0.50-0.74), good (0.75-0.90), or excellent (>0.90) agreement.

^dMVPA: moderate-to-vigorous physical activity.

^eLPA: light physical activity.
