“…The studies reviewed were concerned with reducing alcohol consumption [ 50 , 51 ], smoking cessation [ 36 , 47 ], predicting adherence to medicines [ 48 , 52 ], promoting hand hygiene [ 53 ], nutrition-related intervention, such as promoting whole-grain foods by dieticians [ 37 ], and food safety [ 38 ], physical activity [ 39 ], and weight control [ 40 , 54 ], sexual behaviour related interventions, such as promoting safer sex practices [ 41 , 55 , 56 ], traffic-related interventions, such as promoting school-age cyclists to wear safety helmets [ 42 ], and promoting drivers’ compliance with speed limits [ 43 ], and work-related interventions, such as promoting work health and safety [ 57 ]. In addition to the above, TPB-based interventions have been applied in other domains, such as environment and sustainability [ 44 , 58 , 59 ], reuse [ 60 ], recycling [ 35 , 45 ], and intention to donate to charity [ 61 ]. The effectiveness of TPB-based interventions in predicting behavioural changes is illustrated in the quantitative meta-analysis review of 185 independent studies published up to the end of 1997, where it was found that across all behaviours, the average multiple correlations of intention and PBC with behaviour was 0.52, accounting for 27% of the variance, and the average multiple correlations of attitude, subjective norm, and PBC with intention was 0.63, accounting for 39% of the variance [ 6 ].…”
