“…Twelve studies (50%) evaluated the CE-informed intervention, out of which eight studies conducted process evaluations ( 3 , 18 , 62 , 68 , 70 – 72 , 78 ); three studies conducted formative, process, and outcome evaluations ( 59 , 66 , 67 ); and one study conducted an outcome evaluation only ( 74 ). Areas of CE commonalities in terms of effectiveness include conducting the research within the context of health issues of high perceived severity ( 3 , 4 , 18 , 59 , 60 , 62 , 65 , 66 , 69 , 71 , 76 ) and conducting needs assessments to identify barriers specific to each community ( 3 , 4 , 18 , 59 , 60 , 62 , 65 , 66 , 69 , 71 , 76 ) ( Supplementary Table 2 ).…”
