Jay Levy and colleagues’ “Cross-Cultural Dialogues on Homelessness: From Pretreatment Strategies to Psychologically Informed Environments” provides wonderful insight into the profound relationship-building that is the core of street outreach to the unsheltered homeless. Jay distills many decades of his own street experience, and by cross comparing his brilliant schema of Pretreatment with the British model of Psychologically Informed Environments (PIE), he reveals the underlying common processes of effective street engagement. Essentially, Jay shows us how to compassionately embrace the reality of those who fall within the underwater portion of the “pre-contemplative” iceberg of behavioral change. As a long-time practitioner of street medicine, I recommend this book to anyone who seeks that sacred place on the streets where healing begins.

In  Cross-Cultural Dialogues on Homelessness, Jay Levy and co-authors provide the conceptual tools, the hitherto “missing language”, needed by practitioners and policy makers working with excluded individuals. This well-written and insightful book outlines the psychologically informed approach that has been successfully used in the US, UK and other countries to re-integrate people who have experienced homelessness, severe mental illness and, frequently, other traumatic life events. This book has been informed by the authors’ practice and should come with a warning: it will revolutionise how you work – irreversibly and, undoubtedly, for the better.
