Suicide is a leading cause of premature death for autistic individuals. The autism community has identified suicide prevention as a top priority, yet there is a large evidence gap about best practices to reduce suicide risk in autistic individuals. The presenters will discuss a recently funded Patient-Centered Outcomes Research Institute (PCORI) study comparing the effectiveness of two suicide prevention interventions for autistic adolescents and young adults. The presenters will highlight the value of stakeholder engagement and describe effective practices for meaningful and authentic inclusion of autistic individuals and their family members as research partners. They will describe how autistic co-researchers have contributed to study design decisions and study team considerations in instrumental ways. Strategies that could be used by other stakeholders to promote meaningful partnership will be highlighted.
