Homeless Population and Mental Health: Impact of Primer la Llar Program

The main goal is to evaluate the impact of the Primer La Llar housing program for the homeless population on the mental health of the participants. The hypothesis is that the housing program, which follows Housing first model, for the homeless population has a positive impact on the mental health of the participants, compared to the group that does not receive the intervention -treatment as usual group (meaning the "positive impact" a lower score on the symptomatology scales and lower toxic intake in the group receiving the intervention).
