Purpose: A deeper understanding was sought of what peer-based social support means to young people with juvenile arthritis within the UK and ways in which it could be best provided. Design and Methods: A secondary analysis of underused, descriptively rich data relating to peer-based support contributed by young people with juvenile arthritis, their parents/carers and healthcare professionals from a qualitative study (seeking their views on a potential self-management mobile-app) was carried out using methods suggested by Interpretive Phenomenological Analysis. Results: Peer-based support can provide a new kind of ‘normality’ for young people with juvenile arthritis, including greater understanding, relief, reassurance, shared learning and increased self-efficacy. However, the risk of stigma through this shared identity suggests a need to offer various forms of access including using new electronic media. Conclusion and Implications: The evidence suggests that although desired, the potential social cost of identifying with peers living with juvenile arthritis is influenced by the way such support is provided, which in turn impacts on how readily it will be accessed. This suggests the need to provide various means of accessing peer-based contact, including electronic media, to ensure that young people with juvenile arthritis benefit. Therefore, when promoting and supporting peer-based social support, as far as possible, professionals need to individualise ways in which such support can be accessed because there is no ‘one size fits all’ approach.
