Abstract

Background

Uptake of human papillomavirus (HPV) vaccination is high overall but there are disparities in uptake, particularly by ethnicity. Incentivising vaccination consent form return is a promising approach to increase vaccination uptake. As part of a randomised feasibility trial we qualitatively assessed the acceptability of increasing uptake of HPV vaccination by incentivising consent form return.

Methods

In the context of a two-arm, cluster randomised feasibility trial, qualitative free-text questionnaire responses were collected from adolescent girls (n = 181) and their parents (n = 61), assessing the acceptability of an incentive intervention to increase HPV vaccination consent form return. In the incentive intervention arm, girls who returned a signed consent form (regardless of whether consent was given or refused), had a 1-in-10 chance of winning a £50 shopping voucher. Telephone interviews were also conducted with members of staff from participating schools (n = 6), assessing the acceptability of the incentive. Data were analysed thematically.

Results

Girls and parents provided a mix of positive, negative and ambivalent responses about the use of the incentive to encourage HPV vaccination consent form return. Both girls and parents held misconceptions about the nature of the incentive, wrongly believing that the incentive was dependent on vaccination receipt rather than consent form return. School staff members also expressed a mix of opinions on the acceptability of the incentive, including perceptions of effectiveness and ethics.

Conclusions

The use of an incentive intervention to encourage the return of HPV vaccination consent forms was found to be moderately acceptable to those receiving and delivering the intervention, although a number of changes are required to improve this. In particular, improving communication about the nature of the incentive to reduce misconceptions is vital. These findings suggest that incentivising consent form return may be an acceptable means of improving HPV vaccination rates, should improvements be made.

Footnotes
1
Where the term ‘parent’ is used, we are referring to any adult with parental responsibility.
 
2
Love2Shop vouchers are gift vouchers that can be spent in a range of high street shops, restaurants and major attractions.
 
3
By ‘deliverers’ we refer to all school staff members who participated in the trial, in both the incentive intervention arm and standard invitation arm. There was only one staff member in the standard invitation arm who participated in an interview. Despite not delivering the intervention, they provided feedback on the use of such an incentive.
