WHO has progressively strengthened its work for adolescent health, growing its portfolio of research, norms and standards, country support and advocacy, and expanding the scope of work across over 17 departments, regional and country offices to address the multifaceted needs of the global adolescent population. Central to a coordinated approach to adolescent health across the organization is the HQ Interdepartmental Technical Working Group on Adolescent Health and Well-being. In 2021, the group produced the first report on its work on adolescent health and well-being, celebrating efforts across many areas of work and all levels of the organization. This is the second in the series of biennial reports that comes on the wake of the Global Forum for Adolescents 2023 and is powered by its 1.8 Billion Young People for Change campaign. The report describes WHO’s efforts to elevate adolescent health and well-being through collaboration and by coordinating new initiatives, addressing emerging needs and establishing ambitious objectives with its development partners and adolescents. Target audience: this WHO serial publication is designed to be used by policy-makers, media and donors.

Adolescents face unique pressures and worries. Will they pass high school? Should they go to college? Will they find love? And what ways do they want to act in the world? The uncertainty surrounding the future can be overwhelming. Sadly, and all too often, if things don’t go smoothly, adolescents will begin labeling themselves as losers, unpopular, unattractive, weird, or dumb. And, let’s not forget the ubiquitous ‘not good enough’ story that often begins during these formative years. These labels are often carried forward throughout life. So what can you do, now, to help lighten this lifelong burden? The Thriving Adolescent offers teachers, counselors, and mental health professionals powerful techniques for working with adolescents. Based in proven- effective acceptance and commitment therapy (ACT), the skills and tips outlined in this book will help adolescents and teens manage difficult emotions, connect with their values, achieve mindfulness and vitality, and develop positive relationships with friends and family. The evidence-based practices in this book focus on developing a strong sense of self, and will give adolescents the confidence they need to make that difficult transition into adulthood. Whether it’s school, family, or friend related, adolescents experience a profound level of stress, and often they lack the psychological tools to deal with stress in productive ways. The skills we impart to them now will help set the stage for a happy, healthy adulthood. If you work with adolescents or teens, this is a must-have addition to your professional library.
