Understanding homelessness, mental health and substance abuse through a mixed-methods longitudinal approach.

This manuscript outlines the multiple methods utilized in a long-term follow-up of a non-traditional population: Homeless substance abusers in New Orleans. This article addresses qualitative mental health research by outlining steps taken to explore both qualitative and quantitative data sources. By way of qualitative and quantitative methods, this research examines the life course of a sample of New Orleans homeless substance abusers from the time they entered into treatment (1991) until the present and observes the quality of their social bonds and their long-term outcomes. By making use of mixed methods, this research gives a more thorough understanding of mental health, specifically examined through homelessness and substance abuse. [ABSTRACT FROM AUTHOR]
