“…Of these, we defined 27 as conceptually and/or empirically ‘thin’, whereby they provided limited description of intervention implementation and acceptability [ 60 , 68 , 77 – 79 , 81 , 82 , 84 , 85 , 87 , 89 , 91 , 94 , 96 – 98 , 101 , 102 , 106 , 111 – 115 , 117 , 118 , 183 ]. Meanwhile, 23 were considered conceptually and/or empirically ‘rich’, presenting detailed data and analysis of contextual characteristics that might structure intervention functioning through their influence on implementation and acceptability [ 72 , 74 , 80 , 83 , 86 , 93 , 95 , 99 , 100 , 103 – 105 , 107 – 110 , 116 , 119 , 175 , 182 , 184 – 186 ]. This set of rich process evaluations had theoretical generalisability beyond the immediate evaluation context.…”
