I worked on this project during an internship at the Johns Hopkins School of Medicine Department of General Pediatrics and Adolescent Medicine, during which time I was supervised by Dr. Sarah Lindstrom Johnson. I had been inspired by Dr. Lindstom Johnson’s work on adolescent ecology and future orientation, and explored this idea by conducting qualitative interviews with adolescents participating in a longitudinal, mixed-methods study. While previous scholars described adolescent behavioral transition as a one-time event, our participants described transitioning into and out of periods of increased and decreased risk behavior at various points. These transitions were influenced by their family members, peers, schools, and neighborhoods. Note that while the paper was originally published in 2015, it was reprinted by Youth & Society in 2018.
