Common Humanity as an Under-acknowledged Mechanism for Mental Health Peer Support

Abstract

Abstract Mental health peer support (PS) is a relational approach to recovery. Service users are helped through a relationship focused on connection with a PS worker who shares similar experiences. Despite the strong evidence base, the mechanisms of action for mental health PS are under-researched. Several theories have been proposed to explain the mechanisms, including social comparison theory (SCT). SCT highlights the benefits arising from emphasising differences between a service user and the PS worker. An unintended consequence is that connection between them may be reduced. We propose common humanity (CH) as an under-acknowledged mechanism of action. CH is an experience recognising that there are other people living with similar suffering, and helps us regulate emotions. A CH-informed connection-based PS relationship may help a service user in different ways from a SCT-informed comparison-based PS relationship. Future PS research can investigate emotional self-regulation to establish whether CH-related outcomes arise from PS.
