Sponsorship is a key feature of traditional drug and alcohol self-help groups. It is a source of interpersonal support provided by an individual who is in a more advanced stage of recovery to an individual at an earlier stage of recovery. Whilst it is widely recognised that sponsorship is beneficial to the person receiving it, little is known about the psychological and social benefits that sponsors derive from providing sponsorship to others. We conducted in-depth qualitative interviews with 36 long-term self-help users (6 months-10 years) with experience of sponsoring the recovery of others, recruited from three traditional types of self-help groups in the North of England. Interviews examined sponsors' experiences of providing sponsorship within their own recovery process. Sponsors reported that providing sponsorship to others increased their own self-awareness, social skills, and social competence when it came to engaging with others. In addition, sponsors derived an increased sense of psychological wellbeing and positive social approval from helping others. Over the longer term, sponsorship becomes a meaningful and purposeful activity as it allows those providing it to be productive, make meaning and maintain a non-addicted identity. Additionally, sponsorship is a process which is beneficial for those who have little access to wider social networks.
