All partners contributed with national data for all the study sections. The scientific common phases were: 1) Measures translation with a common procedure; 2) Data gathering in different territories; exeption for Citizen's study perforrmed by telefone.3) data analysis performed by the research leading teams; 4) Outputs and Deliverables internally shared for feedback and further submission. The Citizens Study developed with two components (KAP+WTP) Knowledge, Attitudes and Practices and Willingness to Pay. Results indicate that EU Citizens are favourable to more governmental investments to reverse Homelessness, 49% are willing to pay more taxes for HF. Service User’s Study homeless adults enrolled in either Housing First (HF) or Other Services (OS) in the eight Partner’s countries. Participants at T0+T1data demonstrated significant housing stability for HF, positive results on capabilities development (health, emotions, thoughts and relationships, and appreciation of life). Service Provider’s Study Analysed perspectives of service providers working with homeless people; results indicate common values HF and OS Teams, but different approaches for advocacy and reversing the concrete situation of homelessness; HF Teams favour autonomy of roles, recognition, and leadership. Social Policy Study, the qualitative comparative study of social policies major result is that HF is already integrated in most policies, that civic society was the major source of encouragement for policy development, and from the socio-political stakeholders the panorama is that there is a wide variation of the HF implemented programs in the Cities, and that the knowledge about these programs still needs to be strengthened. Comparative Analysis HF Programs implemented have a more positive attitude towards the focus on reversing homelessness, educational level is associated with favouring governmental investment and willingness to pay. Sociopolitical stakeholders consider financial governmental investment crucial, but the implementation of programs is better when implemented by civic society organizations.
