  1. Adolescent femalesknowledge, beliefs and intended behaviours surrounding the HPV vaccine Flora Doogan Janet Tucker Maggie Cruickshank

  2. Outline • Background • Need for research • Methodology • Results • Summary

  3. Background • 2008 • National HPV vaccination programme introduced in the UK. • 3 year vaccination ‘catch up’ programme for girls aged up to 18 years. • 2011 • ‘Catch up’ cohort now eligible for cervical screening in Scotland. • Vaccine uptake in catch-up cohort much lower than new cohort.

  4. The need for research... • 1) Studies in adolescents have shown that knowledge and attitudes towards HPV vaccination are poor. 1, 2 • Will attendance at cervical screening decline? • Will young women’s sexual and reproductive health be at risk? • These studies are not representative of the population.

  5. The need for research... • 2) Women of lower socioeconomic status have lower attendance at cervical screening and colposcopy and a higher risk of cervical cancer.4 • Health Belief Model “Behaviour is a set of core beliefs that have been redefined over years.” • Current beliefs are the foundations for behaviour in the future

  6. Aim 1o To examine the knowledge, beliefs and intended behaviours of adolescent girls on HPV, HPV vaccination and cervical screening 2o Compare differences by socioeconomic group intake of the school attended

  7. Method • Developed 30 item questionnaire • Multi-level approval • 3 (of 7) schools accepted the invitation • Parent information and opt-out • Pupil information and consent • Questionnaire administered to girls in S3/S4 in PSE classes • Thank you slips with link to sources of guidance • Indicators of socio-economic status at school level • Analysis done in SPSS

  8. Results • 425 invited • 2 PSE classes did not run questionnaire • 78% response rate • 85.4% of participants reported that they had received all 3 doses of the vaccine. • Only 36.6% of participants recalled reading a vaccine information leaflet. • Only 17.6% recalled receiving spoken information at school.

  13. School with the lowest socio-demographic had significantly less positive beliefs and intended behaviour towards screening (p= <0.001). A B C Figure 2: Box plot diagram describing median scores of beliefs and behaviour across 3 schools in Aberdeen.

  14. Results • 12% of participants left free text comments. “I don't actually know what HPV is or what the jab does. I was told it only lasts 6 years. If I knew before I wouldn't have got it.” “I thought if you got the jab you didn’t have to get a screening test.” “I remember not so long ago my mum got invited for cervical screening but she didn’t go, so I didn’t think it was that important.” Box 1: Free text comments illustrating concerns in understanding on HPV and vaccine.

  15. Summary • In girls 1-2 years after vaccination... • HPV knowledge was low • Beliefs held were positive • The intention to attend for cervical screening was high • Significant differences between socio-demographic intake

  16. Implications • Full vaccination against HPV does not mean that the individuals understand what this means. • There is a need for appropriate and relevant educational interventions to ensure that the emerging vaccinated cohort appreciate the importance of cervical screening in the future.
