A new study has revealed that two-thirds of homeless individuals are struggling with some form of mental illness, with rates significantly higher among men compared to women. The research, led by Rebecca Barry and her team at the University of Calgary, analyzed data from 85 rigorous studies involving over 48,000 homeless individuals in affluent countries like the United States, Canada, and Germany.
The most common mental disorders among the homeless population included substance use disorders, antisocial personality disorders, major depression, and general mood disorders. The study found that 67% of homeless people currently have some form of mental illness, while 77% have experienced mental illness at some point in their lives.
These rates are much higher than those seen in the general population, where only 13% to 15% of individuals battle psychiatric illnesses. Rates of bipolar disorder among homeless individuals were over eight times higher than in the general population, along with similarly high rates for other disorders like antisocial personality disorder, psychotic disorders, PTSD, substance abuse, and mood disorders.
Barry’s team also noted a potential increase in the number of mentally ill individuals living on the streets or in shelters, possibly due to factors like housing unaffordability, limited access to mental health care, low income, or challenges reintegrating into society after treatment. The researchers emphasized the importance of “housing first” initiatives and assertive community treatment programs to provide comprehensive mental health services to those in need.
