Rippetoe and Rogers (1987) gave women information about breast cancer and examined the effect of this information on the components of the PMT and their relationship to the women’s intentions to practise BSE. The results showed that the best predictors of intentions to practise BSE were response effectiveness, severity and self-efficacy. In a further study, the effects of persuasive appeals for increasing exercise on intentions to exercise were evaluated using the components of the PMT. The results showed that susceptibility and self-efficacy predicted exercise intentions but that none of the variables was related to self-reports of actual behaviour. In another study, Beck and Lund (1981) manipulated dental students’ beliefs about tooth decay using persuasive communication. The results showed that the information increased fear, and that severity and self-efficacy were related to behavioural intentions. Norman et al. (2003) also used the PMT to predict children’s adherence to wearing an eye patch. Parents of children diagnosed with eye problems completed a baseline questionnaire concerning their beliefs and a follow-up questionnaire after two months describing the child’s level of adherence. The results showed that perceived susceptibility and response costs were significant predictors of adherence.
