Key result
Active Australia Survey closely matches accelerometry for measuring moderate-to-vigorous physical activity over 12 months.
Why the study?
The long-term validity of the Active Australia Survey in a cardiac rehabilitation population had not been examined against accelerometry as a reference measure.
Does the Active Australia Survey accurately measure moderate-to-vigorous physical activity compared to accelerometry in cardiac rehabilitation participants?
Cohort (n=61)
Does the Active Australia Survey accurately measure moderate-to-vigorous physical activity compared to accelerometry in cardiac rehabilitation participants?
The Active Australia Survey is an acceptable self-report measure for capturing any time spent in moderate-to-vigorous physical activity among cardiac rehabilitation patients.
Supports Active Australia Survey for MVPA assessment in cardiac rehab; extends validation data but leaves open larger confirmatory studies.
OBJECTIVES: To examine the long-term validity of the Active Australia Survey in a cardiac rehabilitation population using accelerometry as the reference measure. DESIGN: Cohort validation study. METHODS: Cardiac rehabilitation participants with coronary heart disease were recruited to a prospective cohort study. Over 7-days, 61 participants wore an ActiGraph ActiSleep accelerometer (1-second epoch, 10-minute bout) and completed the self-administered Active Australia Survey at baseline, 6-weeks, 6 and 12-months. Total daily moderate-to-vigorous physical activity from both methods was compared using Bland-Altman plots and Spearman rank-order correlations. RESULTS: Participants tended to over-report moderate-to-vigorous physical activity, with more active participants more likely to over-report moderate-to-vigorous physical activity. There was a good level of agreement between the accelerometer 1-second epochs and Active Australia Survey at all time points (mean bias (ratio) 1.04, 1.16, 1.14, and 1.06, respectively), with weak-moderate correlations (ρ = 0.3-0.48). Conversely, there was a poor level of agreement between the accelerometer 10-minute bouts and Active Australia Survey at all time points (mean bias (ratio) 6.78, 9.09, 6.35, and 5.68, respectively), with weak-moderate correlations (ρ = 0.3-0.52). Agreement between the two measures did not improve over time for both 1-second and 10-minute bout accelerometry data. CONCLUSIONS: The Active Australia Survey may be an acceptable self-report measure of moderate-to-vigorous physical activity in cardiac rehabilitation attendees when capturing any time spent in moderate-to-vigorous physical activity. The Active Australia Survey may be useful to routinely monitor physical activity levels over-time in Australian cardiac rehabilitation programs at both individual and group levels.

Freene et al. (2024) conducted a cohort in Coronary heart disease (n=61). Active Australia Survey vs. ActiGraph ActiSleep accelerometer was evaluated on Total daily moderate-to-vigorous physical activity. The Active Australia Survey showed good agreement with 1-second epoch accelerometry for measuring moderate-to-vigorous physical activity (mean bias ratio 1.04-1.16) across 12 months.
