This study investigated strategies for people with intellectual disabilities to self-advocate for inclusion of their priorities in social policy processes in South Africa. Method: Self advocacy strategies were identified through a scoping literature review, a review of self advocacy toolkits and semi structured interviews with people with intellectual disabilities and other stakeholders working at non-governmental and disabled people’s organisations. These data sources were triangulated to identify strategies to upskill and support young adults with intellectual disabilities to share their opinions and perspectives to deepen the diversity of voices engaged in social policy advocacy. Results: Data triangulation identified three core strategies for self advocacy, in person, written strategies and engagement through social media. Discussion: Inclusion of people with intellectual disabilities in civic and political life is crucial, and will only be achieved if self advocates are accepted into the policy-making arena. The cycle of perpetuating exclusion needs to be disrupted, to give people with an intellectual disabilities a say in policy decisions that have an impact on their lives. Conclusion: Adopting strategies which enable the inclusion of the voices of people with intellectual disabilities in civic activities holds potential for diversifying perspectives brought to public participation in policy development and implementation, which is currently primarily the domain of non-disabled citizens.
