Homeless young women ages 18-23 years are the most vulnerable of unstably-housed youth. They are prone to sexually transmitted infections, unplanned pregnancies, and substance use/abuse. The study aim was to determine feasibility and preliminary efficacy of a 4-session intervention delivered at a drop-in site. We wanted to explore differences in indicators of psychological capital between participants in the intervention and those in an attention control group immediately following the intervention and 4 weeks later.
