“…Most (64/80, 80.0%) studies included a measure of efficacy in relation to the targeted movement behavior(s). Of the 74 physical activity interventions, self‐reported methods were most common (i.e., questionnaire and time‐use diary; 31/74, 41.9% 51,61,66,72–75,77,78,86,89,90,93–97,99,105,110,113,116–119,122,123,125,127,131,133 ), followed by device measured (i.e., pedometer, accelerometer, and smartphone app; 24/74, 32.4% 57,60,62,64,65,67,68,70,79–81,83,88,91,96,98,100,102,103,116,120,124,129,130,132 ), and some used a combination of both (6/74, 8.1% 55,58,63,112,115,121 ). There were 14 studies that did not report a specific physical activity‐related outcome measure (14/74, 18.9% 71,76,84,85,91,92,101,104,106–108,114,126,128 ).…”
