Note: AP is activPAL, AG100 is ActiGraph cut-point of 100 counts·min−1, AG150 is ActiGraph 150 cut-point of 150 counts·min−1, T-SQ is total daily sitting questionnaire, D-SQ is domain specific questionnaire, TV-Q is the D-SQ question specifically about TV viewing. Data included 13 participants with valid data for all measures during both the baseline and intervention period. AP, AG100, and AG150 are expressed as a percentage (total sedentary time/wear time) to adjust for differences in wear time.
*Indicates statistically significant difference between conditions . †Indicates significant sensitivity or specificity ().
