​â¶Ä‹Young people aged 16-24 have a higher prevalence of genital chlamydia and gonorrhoea than other age groups. With users, we developed the theory-based  intervention delivered by text message to reduce sexually transmitted infection (STI) by increasing partner notification, condom use, and STI testing before sex with new partners. We evaluated the intervention in the UK using a mixed-methods design, including a parallel-group randomised controlled trial (RCT, n=6248 participants), and a linked qualitative study (semi-structured interviews with n=18 and free-text comments of n=3526 trial participants). During this STIRIG seminar, we will present results of both, the RCT and qualitative study.​

All interventions are co-developed in collaboration with potential users to ensure they are accessible and relevant across socio-economic groups. Cari was the principal investigator for the txt2stop trial, which was the first trial to demonstrate that smoking cessation support delivered by text message more than doubled biochemically verified smoking cessation at 6 months. Most recently Cari has been the principal investigator for the NIHR funded  designed to evaluate the effect of a safer sex intervention delivered by mobile phone on STI infection at one year. She is also working on an NIHR funded project for the development and pilot trial of a weight management after pregnancy intervention delivered by mobile phone. Other current work focuses on development and evaluation of interventions for primary and secondary prevention of cardiovascular disease, interventions to increase use of contraception and digital contraception services in the UK and internationally. She is joint senior author for two Cochrane systematic reviews funded by WHO on the effect of targeted client communication delivered by mobile phone for maternal, neonatal and child health and sexual and reproductive health. She is also an adviser to the WHO M-health working groups for non-communicable disease and the WHO advisory group for maternal, reproductive, neonatal, and child health.
