“…Most of the interventions included feedback on the targeted health behavior (9/11, 82%) [ 12 , 19 , 20 , 36 , 37 , 39 - 41 , 43 - 45 , 48 - 50 ] and self-monitoring of the behavior (8/11, 73%) [ 12 , 19 , 20 , 36 - 41 , 43 , 48 - 52 ]. Other BCTs used included action planning (5/11, 45%) [ 36 , 41 , 43 - 47 ], goal setting (4/11, 36%) [ 12 , 19 , 20 , 37 , 41 , 43 , 48 - 50 ], problem solving (4/11, 36%) [ 12 , 19 , 20 , 37 , 41 , 46 - 50 ], awareness (1/11, 9%) [ 46 , 47 ], verbal persuasion (1/11, 9%) [ 39 , 40 ], commitment (1/11, 9%), self-regulation (1/11, 9%) [ 44 , 45 ], prompts and cues (1/11, 9%), rewards (1/11, 9%), social comparison (1/11, 9%), and relapse prevention (1/11, 9%) [ 43 ]. Although common techniques were identified, they were rarely explained by the authors, which makes their definition and application unclear.…”
