Campaigns and awareness raising strategies in traffic safety — <strong>Deliverable</strong> D-1.1Overall effects according to consequence handling are shown in Table 7.39.Those campaigns showing non-shocking consequences give the largestoverall accident-reducing effect, but differences are not significant. Therewere too few shocking campaigns in the sample to allow for solid conclusionsabout their effects.Campaign effects were also categorized subjectively according to whetherthey incorporated an element of humour. Examples of humour are a comicalcampaign mascot or the use of humour in a television campaign. Only oneaccident effect was for a campaign judged to use humour and so this analysiswas omitted. Results for seatbelt use effects are given in Table 7.40. The useof humour has no clear influence on overall campaign effect in our sample.Table 7.40. Overall effects of road safety campaigns on seatbelt use according to use ofhumour. Results are given after accounting for publication bias. Each overall effect is basedon n individual effects (excluding any artificial effects generated by trim-and-fill).Seatbelt useHumour?effect(%)95%confidenceinterval (%)nSig.?(p < 0.05)Yes +23 (+15;+31) 23 yesNo +30 (+16;+45) 107 yesCampaign effects were further categorized and analysed according to whetherthe evaluated campaign attempted to persuade by highlighting the riskinvolved in unsafe behaviour. Any risk addressed was further categorizedaccording to whether it was risk of detection (by police), risk of harm to self orrisk of harm to others that was addressed. It was possible for any onecampaign to address one, two or all three types of risk. Analyses carried outon this basis are shown in Table 7.41 for accident effects, and in Table 7.42for seatbelt use effects.In terms of effects on accident counts, the results indicate that addressing riskis beneficial, but that it is more beneficial if risk of detection is addressed,rather than risk of harm to self or others. The seatbelt use results suggest thataddressing risk is not beneficial.86
