Social researchers continue to strive to understand the development and social decision-making processes of homeless adolescents. While it has been established that attachment is a salient factor with regard to childhood maltreatment and later psychosocial problems, there is a dearth of information on how homeless youths' thoughts and feelings about attachment may also be linked to behavioral risks including alcohol and substance use. This exploratory study examines older homeless adolescent's perspectives on attachment, trauma, and substance use via the semistructured Adult Attachment Interview and survey data. The findings illuminate the relationship between these factors and implications for future research and work with this population.
