Impact of Peer Mentors on Individuals Transitioning to Adult Eating Disorder Treatment

This feasibility study will incorporate quantitative and qualitative methods and utilizes an uncontrolled pretest-posttest quasi-experimental design to examine the effectiveness and acceptability of a peer mentor delivered intervention that aims to improve transitions to adult-oriented care for patients with eating disorders (EDs) aged 16-24. Youth will be recruited from community-based clinics, hospital programs, and private practices where youth- or adult-oriented ED treatment is delivered across Nova Scotia, New Brunswick, and Prince Edward Island. Clinicians in these settings will be asked to identify potentially eligible youth who will be transitioning to adult-oriented ED care. Potential participants who are interested in participating and provide written consent will meet with a research team member for a screening meeting to determine their eligibility status. Screening will involve the Structured Clinical Interview for DSM-5 Research Version (SCID-5-RV) and the Columbia Suicide Severity Rating Scale (C-SSRS). All screening information will be reviewed by the PI (Dr. Keshen). Participants who are not interested in the study or who fail to meet the eligibility criteria will be given standard options available to treatment age youth. Youth participants who are found eligible will be connected with a trained peer mentor for a 3-6 month transition intervention. Youth and their peer mentor will meet weekly, bi-weekly, or monthly depending on the phase of the intervention and the needs of the youth. The intervention is divided into 3 phases: phase 1 includes building a sense of trust, rapport, and motivation, as well as the identification of goals, strengths, challenges and barriers related to transition; phase 2 focuses on self-reflection, problem-solving, and transition planning; and phase 3 involves the gradual tapering off and conclusion of the peer mentor relationship. Youth participants will be asked to complete questionnaire packages before beginning the intervention, after completing the intervention, and 12 months after beginning the intervention. Some youth will also be asked to participate in one-on-one interviews with a research team member at these same time-points. Some youth participants will be asked if they would like to involve a carer in the study, as well. Carers will be invited to participate in a one-on-one interview with a research team member 12 months after the youth they are caring for began the intervention. Peer mentors will be invited to participate in one-on-one interviews at the end of the study. The aim of the interviews is to understand experiences with eating disorder treatment, transitions in care, and the peer mentor intervention.
