Abstract

An extended Theory of Planned Behaviour (Ajzen, 1991:2002; Ajzen and Fishbein, 1980) was employed to examine intentions of 18-26 year old British females towards potential HPV vaccination. Cross-sectional questionnaires based around this TPB extension were completed by British females (N = 149). Three intervention groups were formed by supplying participants with positive, negative or neutral HPV vaccination information prior to questionnaire completion. Hierarchical multiple linear regression analysis revealed that the extended TPB was better at predicting HPV vaccination intention, accounting for 60.3% of variation, compared to 58.5% accounted for by the standard TPB. A one-way ANOVA found intentions and attitudes following a publicised news item on a death after HPV vaccination were significantly lower than those recorded before. However, a one-way ANOVA found no intervention group difference effect on intention. These results strongly suggest that women currently excluded from NHS HPV vaccination would intend to accept the vaccine if offered.
