Besides, perceived susceptibility has been shown to be an important factor of preventive behavior according to health theory (e.g., the Health Belief Model; e.g., Schwarzer, 2001) and research (e.g., Brewer & Fazekas, 2007;.…”

“…The outcome criteria were mothers' perceived daughters' susceptibility and mothers' HPV-vaccination intention. Mothers' perceived daughters' susceptibility towards HPV and towards cervical cancer was measured by 7-point scaled item, each: 'Without the HPV-vaccination, the chances of my daughter for getting infected with HPV (getting cervical cancer) are … '(1 = very small; to 7 = very big) (Pot et al, 2017;Van Keulen et al, 2013). HPV-vaccination intention was measured as a composite of two items: 'Are you planning to have your daughter vaccinated against HPV?'…”

“…and 'What are the chances that you will get your daughter vaccinated against HPV?' (Pot et al, 2017;Van Keulen et al, 2013). Responses were given on a 7-point scale ranging from (1) certainly not/very small/to (7) certainly/very big (Pearson's r = .95).…”

“…Several studies have provided insight in factors constituting HPV-vaccination acceptability (e.g., Alberts et al, 2017;Hofman et al, 2014;Pot et al, 2017;Van Keulen et al, 2013). Results from two Dutch studies among mothers of girls to-be-invited showed that 'modifiable' social-psychological determinants (e.g., perceived daughters' susceptibility towards HPV-related risks) accounted for large proportions of variance in HPV-vaccination intention (Van Keulen et al, 2013;Pot et al, 2017). Mothers' intention, in turn, was found to be the main and stable predictor of their daughters' actual uptake (Pot et al, 2017).…”

This was also found by Hofman and colleagues (2014) among parents of invited girls and is in line with social cognitive models such as the Reasoned Action Approach (Fishbein & Ajzen, 2010).…”

Background:In order to promote HPV-vaccination acceptability among mothers of invited girls, we developed a web-based, tailored intervention. This study reports on an experimental pretest for the component of this intervention targeting mothers' perceptions of their daughters' susceptibility towards HPV-related risk factors. Statistical versus narrative risk information was pretested as research results remain to be mixed on the surplus value of one type over the other in influencing mothers' perceptions of their daughters' susceptibility. Methods: We used data from 375 mothers of girls-to-be invited to the HPV-vaccination round 2014, who were derived from the Dutch National Immunization Register. They were randomly assigned to one of four conditions in a 2 (statistical information: yes or no) × 2 (narrative information: yes or no) between-subjects factorial design. Findings: Mothers who received statistical information felt their daughters were more susceptible towards HPV than mothers who received no statistical information. No main or interaction effects with narrative information were found. The effect of statistical information on mothers' perceptions of their daughters' susceptibility towards HPV was not moderated by perceived comprehensibility, credibility or novelty of the risk information, nor mediated by message-induced imaginability, elaboration, personal relevance, or defensive reactions. However, in secondary analyses, in which we only included the statistical and narrative condition, we found personal relevance to mediate the effect of statistical information (independent variable) on mothers' perceptions of their daughters' susceptibility towards HPV (dependent variable). Discussion: Statistical risk information appeared most effective in increasing mothers' perceptions of their daughters' susceptibility towards HPV and was therefore included in the web-based, tailored intervention promoting HPV-vaccination acceptability.
