Although youth advisory structures (YASs) have proliferated internationally to facilitate the voice of young people, little is known about the practices of such groups, especially in the United States. To address this gap of knowledge, this study describes the findings of a scoping review of scholarly research on YAS in the United States. The review found that although the use of YAS is increasing, current scholarship offers little information about YAS processes or how youth are engaged. Most YAS in the review partnered with marginalized young people to inform research and programming around sensitive health topics, such as human immunodeficiency virus prevention. Youth who participated in YAS experienced positive outcomes such as leadership and skill development, healthier decision‐making, and confidence. Although most studies involved youth in minimal ways, there is a growing body of literature where youth are engaged in long‐term partnerships that support positive youth development. This review details other key characteristics of YAS and provides recommendations for best practices, such as building consensus around terms used to refer to YAS and promoting the dissemination of process details around YAS facilitation.
