Once housed in supportive living residences, formerly homeless adults with mental illness commonly continue to experience high levels of stress, anxiety, depression, and post-traumatic stress disorder (PTSD), despite receiving medical and psychiatric services. Stress that is not sufficiently addressed can frequently lead to rehospitalizations and subsequent loss of housing. Although stress has been successfully treated with anti-anxiety pharmaceuticals, cognitive behavioral therapies, and support groups in adults in the larger population, formerly homeless adults with chronic mental illness tend to experience greater treatment resistance to such interventions or respond positively for short intervals and then relapse.
