paragraph_text: Homeless population
  
  Mental illness is thought to be highly prevalent among homeless populations, though access to proper diagnoses is limited. An article written by Lisa Goodman and her colleagues summarized Smith's research into PTSD in homeless single women and mothers in St. Louis, Missouri, which found that 53% of the respondents met diagnostic criteria, and which describes homelessness as a risk factor for mental illness. At least two commonly reported symptoms of psychological trauma, social disaffiliation and learned helplessness are highly prevalent among homeless individuals and families.
  
  While mental illness is prevalent, people infrequently receive appropriate care. Case management linked to other services is an effective care approach for improving symptoms in people experiencing homelessness. Case management reduced admission to hospitals, and it reduced substance use by those with substance abuse problems more than typical care.
