Book excerpt: There were more visits to peer support/self-help groups last year, than there were visits to the offices of mental health professionals. Peer support groups have exploded in popularity, as the public and the healthcare community recognize that they provide an effective complement to formal care, and improve the chance that many participants will have better healthcare outcomes. Few peer support/self-help group leaders have more than minimal training in how to lead a group successfully. This is unfortunate, as leading a self-help group is often challenging. This pocket resource is designed to provide easy access to key information and strategies to help Peer Specialists and other lay group leaders develop and expand their group facilitation skills so they can lead healthy thriving peer support groups.
