The 6 guiding principles of the Bridging the Transition Framework, a frame designed to guide the practice, research and policy in homelessness prevention. The 6 guiding principles include: 1) Housing First; 2) Recovery; 3) Harm Reduction; 4) Social Justice; 5) Intersectionality; and 6) Trauma and Violence-Informed Care. 6 Guiding Principles In using the Bridging the Transition Framework, we encourage the use of 6 Guiding Principles that are supported by practice and research evidence and known to be effective for homelessness prevention. These include: Social Justice Housing First Recovery Harm Reduction Trauma and Violence-Informed Care Intersectionality Social Justice Social justice is an interdisciplinary concept acknowledging the ways in which resources are distributed in society, with an interest in advancing the common well-being of all by seeking to distribute resources in a more equitable manner [1]. Social justice is fundamentally connected with human rights in that it aims to elevate the well-being of materially and socially oppressed groups in society [1]. Homelessness is the direct result of poverty [2], and is an issue for which a social justice lens is particularly useful. Many persons who experience homelessness live in situations of extreme deprivation in countries that have ample resources for all. As health and social care proivders, we have a role in seeking to realize social justice for individuals who experience homelessness through our individual encounters, and through the use of community and population level approaches. Learn more about Social Justice by reading Chapter 9 in the Bridging the Transition Book: Guiding Principles of the Bridging the Transition Framework: Social Justice . For the perspectives of service providers, researchers and persons with lived experiences of homelessness on the importance of social justice as a perspective in homelessness prevention, watch the video below. Anchor 1 Housing First Housing First (HF) is a person-centred philosophy of practice which emphasizes that individuals are housing ready from the moment that they are born, and do not need to prove their ability to be “housing ready” prior to being offered permanent housing [3]. HF emerged out of criticisms of the “treatment first” or “staircase model” approach, which emphasized the treatment of mental health and substance use challenges before an individual could be regarded as “housing ready.” These “treatment first” approaches emphasized the use of shelters and transitional housing, and are often seen as inhumane because they prolong homelessness for individuals who already live with multiple health and social challenges. Practitioners, researchers policymakers and advocates using this framework should emphasize the primacy of permanent housing in their support of persons experiencing homelessness over encouraging “housing readiness."

For the perspectives of service providers, researchers and persons with lived experiences of homelessness on the importance of Housing First as an approach in homelessness prevention, watch the video below. Anchor 2 Recovery Rates of mental illness, trauma, and substance use disorders are known to be high in the homeless population [4]. The recovery model posits that a person living with mental illness and/or substance use disorder can create a life of personal meaning in the face of challenges imposed by a diagnosis [5, 6]. Many individuals living with mental illness, trauma, and substance use difficulties experience symptoms episodically or chronically, meaning that they live with these challenges to a greater or lesser degree in the long term. Adopting a recovery-oriented approach to practice is particularly important given that individuals may become homeless in part due to functional challenges associated with mental illness, and these challenges are likely to persist across the trajectory of homeless to housed. Learn more about the recovery model by reading Chapter 11 in the Bridging the Transition Book: Guiding Principles of the Bridging the Transition Framework: Recovery . For the perspectives of service providers, researchers and persons with lived experiences of homelessness on the importance of the recovery model in homelessness prevention, watch the video below. Anchor 3 Harm Reduction Harm reduction is a philosophy which emphasizes the safety of individuals engaged in activities that have the potential to impose harm such as substance use and sex work [7,8]. Harm reduction approaches encourage the use of a range of practices including the provision of clean and safe tools for administering substances, or by providing condoms and sexual health education. One common misconception is that harm reduction and abstinence approaches are mutually exclusive [9]. Practitioners, researchers, policymakers and advocates should be aware that using a harm reduction philosophy does not preclude supporting individuals with goals related to abstinence or supporting a reduction in behaviours that have the potential to impose harm should a person wish to focus on such goals. Individuals using this framework should employ a harm reduction approach by providing supports aimed at promoting the health and well-being of persons who experience homelessness by encouraging the use of safe strategies. Offering support with abstinence or reducing engagement in a behaviour that palace their health at risk when a service user expresses an interest in such goals is both supportive and person-centred. Such an approach requires the presence of a strong therapeutic alliance, which needs to be developed over time. Abstinence should not be emphasized as a goal if a person does not express an interest in making such a change in their lives, and never as a precondition for accessing services.

For the perspectives of service providers, researchers and persons with lived experiences of homelessness on the importance of harm reduction as a perspective in homelessness prevention, watch the video below. Anchor 4 Anchor 5 Trauma & Violence-Informed Care It is widely recognized that individuals who experience homelessness have endured physical, sexual, and emotional trauma both before and during homelessness [4,10,11]. Homelessness itself has been described as a form of trauma in that the denial of the right to housing can be experienced as deep exclusion and abandonment by one’s community. Knowledge that trauma is more prevalent among persons who experience homelessness means that it is necessary to use approaches that acknowledge the presence of this trauma in the delivery of services. When using this framework, practitioners, researchers, policymakers and advocates are encouraged to use a universal precautions approach to trauma. This means that when individual encounter a person with experiences of homelessness, they should assume that the person has experienced trauma and use evidence-based trauma informed approaches in the delivery of services. One such approach is “Trauma and Violence-Informed Care” (TVIC). TVIC builds on “Trauma Informed Care” (TIC) by acknowledging that individuals may experience trauma both from traumatic experiences (i.e. physical and emotional trauma), and also from the structural environments in which they are situated (i.e. being denied the right to resources for survival, poverty) both historically and in the present [12]. TVIC emphasizes minimizing harm associated with trauma, rather than treating the trauma itself [13]. Approaches that minimize the activation of past and present traumatic experiences including person-centred and strengths-based approaches should be employed by individuals who are using this framework. Learn more about TVIC by reading Chapter 13 in the Bridging the Transition Book: Guiding Principles of the Bridging the Transition Framework: Trauma and Violence-Informed Care . For the perspectives of service providers, researchers and persons with lived experiences of homelessness on the importance of TVIC as a perspective in homelessness prevention, watch the video below. Anchor 6 Intersectionality Intersectionality is an acknowledgement of the ways in which race, gender, ability, sexual orientation andclass intersect to influence social possibilities and health [14]. The fact that persons of colour, men, individuals identifying as LGBTQ2+ , indigenous persons, and individuals living with disabilities are disproportionately represented in statistics on homelessness suggest that these social locations should be accounted for in support services. Often, these social locations layer over one another to create deep degrees of discrimination and health inequities. For example, a racialized woman living with poverty and with mental illness experiences discrimination related to her gender, race, disability, and class.
