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.
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.
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.
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.

人乳头瘤病毒（HPV）疫苗接种总体上很高，但接种率存在差异，特别是在族裔方面。激励接种同意书的返回是增加疫苗接种率的一种有前途的方法。作为一项两臂、集群随机可行性试验的一部分，我们从定性上评估了通过激励同意书的返回来增加 HPV 疫苗接种率的可接受性。
在一项两臂、集群随机可行性试验的背景下，从青少年女孩（n=181）及其父母（n=61）中收集了定性自由文本问卷的回复，评估了激励干预措施增加 HPV 疫苗接种同意书返回的可接受性。在激励干预组中，返回已签署同意书的女孩（无论同意或拒绝），有 1/10 的机会赢得 50 英镑的购物券。还对参与学校的工作人员（n=6）进行了电话访谈，评估了激励措施的可接受性。数据采用主题分析。
女孩和父母对使用激励措施鼓励 HPV 疫苗接种同意书返回的态度存在积极、消极和矛盾的混合反应。女孩和父母都对激励措施的性质存在误解，错误地认为激励措施取决于疫苗接种而不是同意书的返回。学校工作人员对激励措施的可接受性也持混合意见，包括对有效性和道德性的看法。
向接受和提供干预措施的人发现，使用激励干预措施来鼓励 HPV 疫苗接种同意书的返回是可以接受的，但需要进行一些改进。特别是，改进关于激励措施性质的沟通，以减少误解，是至关重要的。这些发现表明，激励同意书的返回可能是提高 HPV 疫苗接种率的一种可接受的方法，如果进行改进的话。
