Authoring Action (A2) is a youth-focused, arts-based, afterschool and summer program. A2's mission is "to transform the lives of youth and the world through the power of creative writing, spoken word, visual and media arts, film-making and leadership education that promotes positive systemic change." Using in-depth interviews, this study aimed to understand how this arts-based program affects youth development. Participants in this study (N=36) were alums of Authoring Action (A2), interviewed when they were between the ages of 17-32. Over half identified as female (N=21). Most A2 participants were youth of color and participated in A2 between ages 13-17. Interview data were coded following several steps: generating initial codes, searching for themes, reviewing themes, defining and naming themes, and generating a report. Four themes describe the impacts of A2 for program participants: "communication," "cathartic and transformative experiences," "connection," and "critical consciousness." Programmatic features--getting paid to participate, shared group identity, and open access to program leaders and peers--were meaningful to youth participants. The mission and programmatic features of A2 support youth development; we discuss practices that may benefit other arts-based youth programs and the implications of such practices for youth development.
