Understand the linkages between trauma and homelessness, including sexual, psychological, or physical abuse. Homelessness is traumatic. People experiencing homelessness often live with a multitude of personal challenges, such as the sudden loss of a home or adjusting to conditions of shelter life. Some people, particularly women, may have histories of trauma, including sexual, psychological, or physical abuse. Most families who are experiencing homelessness are headed by single women, and these women experience posttraumatic stress disorder, depression, and substance use at a rate higher than the national average. Within the larger society, people experiencing homelessness often are marginalized, isolated, and discriminated against. Additionally, they are highly vulnerable to violence and victimization, and re-traumatization becomes a distinct possibility. Given these concerns, it is important to understand the linkages between trauma and homelessness, and the impact on ensuring quality care.
