Working in a homeless youth shelter in a major Eastern Canadian city, 35 homeless males and females, aged 16-24, engaged in a participatory action research (PAR) project over a one-year period. In the study, the participants systematically brainstormed 107 potential research themes pertaining to their experiences, concerns, and interests in youth homelessness. From these themes, the youth prioritized stereotyping and stigmatization, issues that they wanted to better understand, address and take action on in their various lifeworlds. After the youth considered a variety of representative art forms and artworks from participants in the study, they selected a theatre script, “The Other Side of the Door,” to represent their research findings. From this play, the youth selected ‘who is a homeless youth,’ and the relationship of parenting to youth homelessness as key themes. By including and analyzing the youths’ decisions and ideas about their research priorities and findings, new insights and understandings are contributed to scholarly research about youth homelessness.
