This book provides an overview of risk and protective factors for lesbian, gay, bisexual, transgender, and queer (LGBTQ+) youth and emerging adults to inform the clinical practice of mental health professionals who work with this population. Grounded in multicultural, intersectional, and positive youth development frameworks, this book emphasizes holistic health perspectives, integrated care approaches (of mental health with general health service delivery), and interdisciplinary team efforts targeting both the psychological and physical health needs of children, adolescents, and emerging adults. Mental health professionals and educators at any stage of their career who want to expand their knowledge base and improve their skill level for working effectively with LGBTQ+ children, adolescents, and emerging adults will find this a thought-provoking and illuminating resource.
