Self-Help Plus (SH+) has been developed as a five-session, group-based stress management course. It is suitable for all settings where there are populations affected by adversity. It can be used to help reduce psychological distress in adults, regardless of whether they have a diagnosable mental health condition or not and has been shown to prevent the onset of mental disorders in adults. SH+ uses pre-recorded audio and an illustrated guide to teach stress management skills. This innovative format makes it possible for supervised non-specialists to complete a short training on SH+ and then deliver it to large groups of people (e.g. up to approximately 30 at a time). SH+ is one of a number of evidence-based scalable psychological interventions published by WHO and can be offered alongside other mental health interventions or community programming. This manual is for facilitators, supervisors and organizations implementing SH+. When we refer to “you” in the manual, we are addressing facilitators.
