Methods Children wore an accelerometer, and mean minutes of moderate - to - vigorous physical activity (MVPA) per day, counts per minute (CPM) and achievement of national MVPA guidelines were derived.

Although PA was measured objectively using accelerometers, we can not rule out that the recorded levels of PA are subject to bias, as participants might have changed their performance because they knew they were being observed.37 This would not, however, have biased estimates of the association with depressive symptoms unless depressed individuals respond differently to wearing accelerometers.

MVPA models were estimated using data from families whose children wore the accelerometer for at least 4 of 7 days and had valid data for all predictors (N = 311 for authoritative and authoritarian models and 313 for permissive models).

As noted previously, analyses treating MVPA as the outcome included only those children who wore the accelerometer for at least 4 of the requested 7 days (N = 322).

Chi square analyses and t - tests were conducted to examine potential differences in the demographic, predictor, and outcome variables as a function of accelerometer wear adherence (wearing the accelerometer for less than 4 versus 4 or more days).

These analyses were limited to children who wore the accelerometer for at least 4 of 7 days.

In addition to observation by another, objective measurement methods can be used, such as accelerometers to record physical activity.77 However, these also have limitations for assessing adherence, especially longer term or with large clinical groups, as the devices are expensive and require the participant to adhere to wearing them.
