About this study

Official title: Examining the Impact of Peer Mentors on Individuals Transitioning to Adult Eating Disorder Treatment: A Feasibility Study

Participants will be males and females aged 16-24 with an eating disorder (ED) diagnosis who are transitioning to adult-oriented ED treatment in Nova Scotia, New Brunswick, or Prince Edward Island. Youth participants will be recruited from community-based clinics, hospital programs, and private practices where ED treatment is delivered. Youth who are interested in participating and provide written consent will be invited to take part in a screening meeting to determine eligibility to participate. Eligible participants will be paired with a peer mentor for a 3-6 month intervention to guide them through the transition to adult-oriented ED treatment. 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 participants, as well as some of their carers and the peer mentors, will be asked to participate in one-on-one interviews about their experiences with transitions in ED care and the peer mentor intervention. The investigators are conducting this study to determine whether the use of peer mentors is an effective and acceptable means of transition support for youth with EDs. The investigators are also interested in better understanding the experiences of carers and peer mentors who are supporting youth with EDs during their transition in care.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Autonomous Motivation

    This will be measured at Baseline, Post-Intervention, and 12-Month Follow-Up, using The Treatment Self-Regulation Questionnaire (TSRQ; Levesque et al., 2007). The TSRQ is a reliable and valid self-report questionnaire that assesses the type of motivation patients use (autonomous or external/controlled) when engaging in a health behaviour or treatment. The TSRQ consists of 12 questions with scores ranging from 1 ("strongly disagree") to 7 ("strongly agree"). The TSRQ can be modified to measure specific health care outcomes (e.g., ED related). Further, the TSRQ has previously been used to detect changes in autonomous motivation before and after health-related interventions, including over six-month timeframes (e.g., Stamp et al., 2016; Knittle et al., 2015). A recent scoping review determined that there are no validated quantitative measures for specifically evaluating mental health related transition interventions for TAY (Cleverly et al., 2018).

    Measured: Baseline, 3-6 months, 12 months

Secondary outcomes (2)
  1. Completed Transitions

    Engagement in adult-oriented service could include: a) one session (or more) of individual psychotherapy aimed at treating the ED (as determined by the PI); b) an admission into AEDP (i.e., group-based Day Program or Inpatient); and c) the youth is on the wait-list to start adult treatment. Initiation of adult services can be through referral from any clinician or self-referral. Although our measurement of a completed transition is a dichotomous variable, we will also collect exploratory data to examine the degree of service uptake in the adult-oriented treatment (low, medium, and high use as defined by McClelland et al., 2020). This will allow us to explore not only whether the youth transitioned or not, but also to what degree they engaged in an adult service after the transition.

    Measured: 12 months

  2. Patient acceptability

    This will be measured at Baseline, Post-Intervention, and 12-Month Follow-Up, using the Health Care Climate Questionnaire (HCCQ; Williams, et al., 1996) at Baseline, Post-Intervention, and 12-Month Follow-Up. The HCCQ measures the extent to which patients feel that providers take full account of their perspective, offer choice and information, encourage self-initiation, provide rationale, and accept patient decisions. The HCCQ is a companion scale to the TSRQ, and has been positively associated with autonomous motivation and treatment adherence (Williams et al., 2006; Chan et al., 2009). The HCCQ is a valid and reliable 6-item self-report questionnaire with scores ranging from 1 ("strongly disagree") to 7 ("strongly agree").

    Measured: Throughout study completion, 12 months
