How does the emotive content of televised anti-smoking mass media campaigns influence monthly calls to the NHS Stop Smoking helpline in England?
Bottom Line: We adjusted for seasonal trends, inflation-adjusted weighted average cigarette prices and other tobacco control policies.We found non-linear associations between exposure to positive and negative emotive campaigns and quitline calls.While positive campaigns were most effective at increasing quitline calls, those with negative emotive content were also found to impact on call rates but only at higher levels of exposure.

Mentions: However, when these associations were fitted with smooth terms, our models indicated that the effects of exposure to both positive and negative emotive campaigns deviated significantly from linearity, as indicated by EDFs that were significantly different from 1. As shown in Fig. 2, the plots of the smooth terms (generated using the package ggplot2) indicate a dose–response relationship between GRPs for positive emotive campaigns and monthly call rates which accelerated at higher levels of exposure. An increase in exposure to positive emotive campaigns from 0 to 400 GRPs resulted in a significant increase in calls in the same month (rate ratio: 1.58, 95% CI: 1.25–2.01) while an increase from 0 to 600 GRPs resulted in more than a quadrupling in the rate of calls (rate ratio: 4.57, 95% CI: 3.47–6.02). By contrast, negative campaigns only increased calls once per capita exposure exceeded 400 GRPs. An increase from 0 to 400 GRPs resulted in a non-significant increase of 3.3% (rate ratio: 1.03, 95% CI: 0.94–1.14), while an increase from 0 to 600 GRPs was associated with a 60.4% (rate ratio: 1.60, 95% CI: 1.37–1.88) increase in calls.
