This two-year study evaluates a mobile phone-based comprehensive sexuality education program designed to support adolescent sexual and reproductive health in Kenya, where rates of teenage pregnancy and sexually transmitted infections remain high. The program, called AskDoki, delivers age-appropriate health information through the WhatsApp platform and is supported by trained youth peer leaders known as Digital Champions, who help adolescents access and use the program. Communities participating in the study are assigned either to receive the AskDoki program with Digital Champion support (intervention communities) or to not receive the program (comparison communities). Adolescents in both intervention and comparison communities complete surveys before the program begins and again six months after implementation of the AskDoki program. The surveys assess health knowledge, attitudes, perceptions, and intended behaviors related to sexual and reproductive health. The study compares changes in survey responses over time between intervention and comparison communities to assess the program's effectiveness. It also evaluates how feasible it is to use Digital Champions to support adolescents' engagement with the mobile program and examines the cost-effectiveness of this approach.
Despite recent improvements in adolescent sexual and reproductive health outcomes in Kenya, rates of unsafe sex, unintended pregnancy, abortion, and sexually transmitted infections remain high. School based comprehensive sexuality education has been shown to improve adolescent sexual and reproductive health outcomes; however, implementation in Kenya is often limited by curriculum constraints and challenges faced by teachers, including limited time, training, and resources. As a result, many adolescents lack access to adequate sexuality education outside the formal school setting. Mobile health technology may offer a cost effective approach to delivering comprehensive sexuality education to adolescents. Amref Health Africa in Kenya developed and pilot tested a mobile, WhatsApp based artificial intelligence chatbot called AskDoki, designed to provide age appropriate comprehensive sexuality education. Preliminary findings suggested that pairing the digital curriculum with trained youth peer leaders-referred to as Digital Champions-may enhance reach, engagement, and effectiveness, particularly among adolescents with limited access to personal mobile devices. Pacific Institute for Research and Evaluation (PIRE), in collaboration with Amref Health Africa, is implementing AskDoki in urban informal settlements in Kenya using a community based approach. The study uses a quasi experimental design in which communities are assigned either to receive the AskDoki program supported by Digital Champions or to serve as comparison communities without access to the intervention. Adolescents aged 15 to 19 years complete surveys at baseline and six months after program implementation. The study evaluates changes over time in key determinants of sexual and reproductive health behaviors, including knowledge, attitudes, perceptions, self efficacy, and behavioral intentions, and compares outcomes between intervention and comparison communities. In addition, the study includes a process evaluation to assess the feasibility, acceptability, and implementation of the Digital Champion strategy. A cost effectiveness analysis is conducted to estimate the cost per adolescent reached and the cost per adolescent achieving improvements in key outcomes.

The study will share the clinical trial survey data.
Data will be made available once analysis is completed or at the time of associated publication. The duration of preservation and sharing of the data will be a minimum of 5 years after the funding period.
The data shared will be made available to researchers at other institutions only per PIRE Institutional Review Board (IRB) approval and after the study is completed and primary findings are published. The rights and privacy of participants will be protected by: (a) IRB review and approval of data sharing activities and (b) releasing only de-identified data. De-identified data will include no information that could link it to individual participants. It is the policy of the PIRE IRB to not share data that are personally identifiable or could lead to disclosure of the identities of individual subjects. Moreover, we will not share data that could cause significant social or legal harm to research participants. Data will be shared for quantitative analyses of primary outcome measures. The dataset(s) that we share will be deposited in a repository such as openICPSR.
