This journal article looks at what factors predict retention rates of young adults who are homeless in a program to reduce alcohol and other drug (AOD) and risky sexual behaviors. As part of a larger intervention program study, the authors identified a sample of 100 participants between the ages of 18 and 25. Nearly half of the participants completed the four-session program. Findings indicate that the factors of sleeping outdoors and receiving the program in the urban setting predicted the participants attending fewer sessions. The authors suggest that these findings can help outreach staff and researchers better prepare methods to engage higher risk homeless youth and retain them in services.
