Desire versus Efficacy in Smokers’ Paradoxical Reactions to Pictorial Health Warnings for Cigarettes
Figure 2
Relations between intention to quit smoking (Iq) and quit efficacy (Eq) by three levels of warning intensity (α) scaled from 0, .5. to 1.0.
Panel A shows the relation using eq. (5) with Es fixed at.5 and β at 3.0. Panel B shows the observed relation using scores predicted by regression model in Table 4 (step 1).
