2nd edition.
The book is aimed at general health workers in low- and middle-income country settings and has some chapters on perinatal mental health. That said, it has definite applicability in high-income country settings too! In the new edition, there has been a big expansion of the psychosocial interventions. Thanks to your advocacy for such a resource being open-access (as the first edition was not), the book is freely available for download: https://www.cambridge.org/core/books/where-there-is-no-psychiatrist/47578A845CAFC7E23A181749A4190B54
