Note. T0, assessment pre-program; T1, assessment post-program (12-week follow-up); PA, physical activity; SD, standard deviation; GRI, Guyatt responsiveness index; IPAQ, International Physical Activity Questionnaire.
a
Percentage and number of participants demonstrating increased PA according to each measure
b
Mean change in PA score for participants identified as having increased PA from baseline to follow-up
c
Standard deviation of change in PA score of participants indicating no change or identified as having decreased PA from baseline to follow-up.
