Group psychological help for adults impaired by distress in communities exposed to adversity With this manual, the World Health Organization (WHO) is responding to requests from colleagues around the world for a group version of the manual Problem Management Plus (PM+), which was developed for adults impaired by distress in communities who are exposed to adversity. Aspects of Cognitive Behavioural Therapy (CBT) have been changed to make them feasible in communities that do not have many specialists. To ensure maximum use, the intervention is developed in such a way that it can help people with depression, anxiety and stress, whether or not exposure to adversity has caused these problems. It can be applied to improve aspects of mental health and psychosocial well-being no matter how severe people’s problems are.
