In addition to standard medical care, adolescents in the experimental group will receive the VP2P support program, a manualized peer-mentorship program that will provide modeling and reinforcement by peers (young adults with JIA aged 16-25 years who have learned to function successfully with their JIA to the mentored participants).

The control group will receive usual care but without the mentorship intervention. They will be offered the VP2P support program after completion of outcome measures (T1 - to be completed online prior to randomization; T2 - at program completion).

The mentorship program will encourage mentored participants to develop and engage in self-management and transition skills and support their practice of these skills. The mentors will present information to mentored participants in a monitored virtual interaction using Skype for 8 weeks (10 total Skype sessions of 30-60 minutes each) to encourage participation in skill building tailored to their needs. All mentors will complete a paid 2.5 day training course and will be supported throughout the duration of the study (consultations with research staff to deal with unforeseen concerns). Mentored participants will complete online outcome measures prior to randomization (T1) and upon study completion (T2).

1. Accrual and Dropout Rates - recruitment and withdrawal rates will be calculated that the end of the study.
2. Compliance (Level of Engagement) - rates of completion of weekly calls and online outcome measures will be calculated that the end of the study - defined as 100% when the participant completes 10 calls over 8 weeks with all online measures completed.
3. Adolescents' Perception of JIA VP2P Program - the acceptability of and satisfaction with the JIA VP2P support program as measured through semi-structured phone interviews with mentees and focus groups with mentors
4. Estimates of Intervention Effects (e.g., effect sizes, variance measures/standard deviation) on health outcomes to inform the calculation of an appropriate sample size for the future definitive multi-centred randomized controlled trial (RCT)

HRQL will be measured by using the Pediatric Quality of Life (PedsQL) Arthritis Module, a 22-item self-report scale which assesses the impact of arthritis in adolescents in terms of physical, psychological and social functioning.
