This book is written for students and clinicians who want to learn about adolescent behavioral health and psychosocial development. It focuses on the experiences of culturally diverse adolescents and families including, but not limited to, diversity based on race, ethnicity, gender identity, sexual orientation, spirituality, ability/disability status, age, nationality, language, and socioeconomic status. Written from a bioecological and strength-based perspective, it views adolescents as having the power to initiate growth and recover from setbacks.
