“…Of the included studies, 86 studies targeted physical activity and within these studies, seventeen measured the intention to be more physically active [86, 87, 89-94, 96, 99, 104-108, 122] 1 , 74 measured physical activity behavior [38, 39, 41-53, 55-69, 71-85, 87, 89, 90, 93-98, 100-103, 105, 106, 109-120] 1 and four measured health outcomes [40,54,60,111]. A total of three studies targeted sedentary behavior, of which one measured the intention to be less sedentary [121] and two measured sedentary behavior [38,47]; none of the studies measured health outcomes. Individuals' intentions to become physically active or less sedentary were usually measured by one to three questionnaire items on a 5-, 6-or 7point scale.…”
