Chapter 4 88 Table 3: Public support following implementation of smoke-free policies from 12 studies investigating pre and post implementation support Author Places covered by smoke-free policy Measurements and comparison Findings Support (percentage, unless otherwise specified) Berg (2020) University campus 1 pre- and 1 postmeasurement among an intervention and control campus Support for smokefree university campuses significantly increased following their introduction, while no changes were seen at the control campus. Support was measured on a 1 to 5 scale, where lower scores indicate a more favourable view towards a smoke-free campus favourable towards smoking. Mean (SD) Campus with policy: Pre: 2.52 (1.50) Post: 1.71 (0.95) Campus without policy: Pre: 2.59 (1.55) Post: 2.63 (1.43) Dono (2014) Public transport stops and playgrounds 2 pre- and 1 postmeasurement for public transport stops; 1 pre- and 1 postmeasurement for children’s playgrounds Support for smokefree public transport stops and children’s playgrounds significantly increased following its introduction, for smokers as well as non-smokers. Pre(2003): 79.6% Pre(2005): 78.3% Post(2013): 93.5% Odds ratio (OR) for post compared to pre intervention level of support OR: 3.8 95%CI (3.0-4.7) Pre(2005): 94.8% Post(2013): 97.8% OR: 2.5 95%CI (1.8-3.6) Farran (2021) University campus 1 pre- and 1 postmeasurement Support for smokefree university campuses did not significantly change following their introduction, for smokers as well as non-smokers. Smokers: Pre: 66.0% Post: 73.2% Non-smokers: Pre: 91.5% Post: 94.6% Hale (2017) Health care grounds 2 postmeasurements Support for smokefree health care grounds significantly increased following their introduction. After 6 months: 70% After 3 years: 74% OR for 6 months vs. 3 years after implementation OR = 1.25 95%CI (1.02-1.52)
