"Life Starts for Me Again." The Social Impact of Psychology on Programs for Homeless People: Solidarity Networks for the Effectiveness of Interventions.

The role of psychology in the improvement of people's lives is consistent, according to the scientific literature review. More and more studies within psychology, and other social sciences, are pointing out the importance of the quality of social interactions on physical and mental health and upon perceived wellbeing. When talking about homelessness, psychology has served these individuals mostly by informing intervention programs related to preventing and responding to substance abuse, healthcare, sexual risks, or mental illnesses, and these are key problems that psychology has also studied and found to be connected to homelessness.
