Hypothesis

Homeless people in Western countries have a higher prevalence of mental disorders compared to the general population.

Conclusion

Homeless individuals are significantly more likely to suffer from alcohol and drug dependence and psychotic disorders than those who are not homeless.

Supporting Evidence

  • Homeless people are more likely to have alcohol and drug dependence.
  • The prevalence of psychotic disorders among the homeless is notably high.
  • Serious mental disorders contribute to increased rates of death and victimization among the homeless.

Takeaway

This study shows that many homeless people have serious mental health issues, like addiction and psychosis, which makes it harder for them to find stable housing.

Methodology

Systematic review and meta-regression analysis of studies on mental disorders among the homeless over the last 40 years.

Potential Biases

Potential biases due to varying definitions of homelessness and mental disorders across studies.

Limitations

The analysis was limited by the small number of relevant studies and the lack of clear definitions of homelessness and mental disorders.

Participant Demographics

Homeless individuals in Western countries.
