OBJECTIVE: Cervical cancer is the fourth most common cancer to occur in women worldwide. In the UK, the NHS cervical screening programme invites eligible individuals to take part in screening every 3-5 years. At present, around 70% of individuals attend screening when invited. The present study aimed to test the effectiveness of a volitional and a motivational intervention alone and in combination on screening uptake at 16-week follow up. METHODS: 14,536 participants were recruited from the list of eligible participants invited for screening in Yorkshire, Humber and the North East regions of England in December 2021. They were randomised to a social norm-based motivational intervention (SNA); implementation intention-based Volitional Help Sheet (VHS); combined intervention (SNA + VHS); or treatment as usual control. The primary outcome was screening uptake measured via patient screening records at 16 weeks. RESULTS: Of the 14,466 participants with eligible data for analysis, 5793 (40.0%) attended for cervical cancer screening in the 16 weeks after the intervention mailing. Both age and deprivation influenced screening uptake, with lower uptake in the youngest individuals and those from more deprived areas. Compared to control, there was no evidence of any benefit from the VHS implementation intervention alone (Adj.OR = 0.99, 95% CI 0.90 to 1.10), the SNA motivational intervention alone (Adj.OR = 0.89; 95% CI: 0.80 to 0.99), or the combined intervention (Adj.OR = 0.96, 95% CI 0.86 to 1.06). CONCLUSION: The study did not support any benefit of either VHS or SNA interventions alone or in combination on cervical cancer screening uptake. It did demonstrate alarmingly low levels of screening uptake at 16 weeks which were well below the average rate. Future research needs to urgently investigate and understand the barriers to uptake following on from the COVID-19 pandemic.
