“…Interventions were evaluated with different study designs. Sixteen used a pre-post design [ 73 , 86 , 88 , 89 , 91 , 92 , 111 , 125 – 127 , 137 , 141 , 143 , 144 , 172 , 174 ], three used a pre-post design with a non-randomised control group [ 120 , 156 , 162 ], five other studies used a pre-post design with no control group, but with the addition of follow-up data collection [ 76 , 93 , 95 , 106 , 177 ], five used a randomised or quasi-randomised controlled trial design [ 83 , 94 , 132 , 154 , 169 ] and thirteen were descriptive case studies or feasibility studies which did not formally evaluate the effectiveness of the interventions they reported [ 74 , 78 , 82 , 100 , 101 , 108 , 116 , 122 , 129 , 160 , 164 , 165 , 178 ]. Only n = 18 (43%) of interventions reported using any theoretical framework, of which n = 13 (31%) drew on psychological theories, and n = 5 (12%) on organisational theories.…”
