About
The goal of this single-blind, randomized controlled pilot study is to evaluate the acceptability and feasibility of an Interpersonal Psychotherapy (IPT) asynchronous self-directed digital training platform for psychiatry residents, as compared to synchronous large group online workshop teaching. This study has the potential to improve access to competency-based training and dissemination of IPT, impacting healthcare delivery with increasing access to this evidence-based psychological depression treatment.
Full description
Background/Rational
The COVID-19 pandemic is expected to have an unprecedented impact on the mental health and well-being of patients, healthcare workers and our society at large. Among these illnesses, depression is expected to be the most prevalent to emerge and is already the leading cause of disability worldwide; it affects up to 1.8 million Canadians. While physical distancing is required to curb the spread of COVID-19, it is well known that social isolation is a substantive risk factor of mental illness and suicide.
Effective treatments exist but as few as 20% of Canadians receive minimally-adequate treatment for depression. One effective treatment for depression includes Interpersonal Psychotherapy (IPT) which may be particularly relevant for the isolation and life changes brought on by the COVID-19 pandemic. IPT is recommended in key consensus guidelines from the World Health Organization and the Canadian Network for Mood and Anxiety Treatments. IPT is a brief, structured psychological treatment that has been shown to effectively reduce depressive symptoms and enhance remission rates for patients across the lifespan. IPT proposes that the key to reducing depression is to increase connection with social supports and help patients work through triggering interpersonal experiences of loss/grief, life changes/social role transitions, interpersonal sensitivity/loneliness, or relational conflicts/role disputes. We selected IPT for three reasons: i) its strong evidence base for effectiveness as an antidepressant treatment, comparable in efficacy to CBT, with fewer patients dropping out of treatments; ii) its effectiveness in treating depression among culturally diverse patients across the lifespan; and iii) its parsimonious approach that is easy to understand and implement. This is critical when training novice clinicians. The poor dissemination of effective psychological therapies such as IPT is partly due to the limited number of available mental health professionals who can train novice clinicians with high fidelity; and one key obstacle is how these individuals are trained. Prior to the COVID-19 pandemic, this typically involved a trainee attending an expert-led workshop and then practicing the treatment under the supervision of someone experienced in delivering that treatment. The recent development of digital training platforms in various psychological treatments has attempted to address this training gap. In addition, web-conferencing applications have opened the door for distance psychotherapy training and supervision.
Online training methods need to be developed and examined to address this significant bottleneck, particularly in light of the current COVID-19 pandemic where in-person trainings have stopped but the need for evidence-based psychotherapy grows. The current study aims to examine two online training methods with consenting psychiatry resident/trainee therapists: a) asynchronous self-directed training through a novel digital training course which they will complete on their own schedule; and b) synchronous large group workshop where residents will participate in a live training workshop at a specific time. Asynchronous training is a more cost-effective and scalable method of training which permits residents (and other trainees) to learn psychotherapy according to their preferred schedules. To date, several asynchronous IPT training courses have been developed, however none have been compared to synchronous large group online workshop. The current study will provide preliminary evidence to examine the acceptability and feasibility of both models among psychiatry residents at University of Toronto affiliated hospitals.
Purpose
The main purpose of the current study is to examine the acceptability and feasibility of a digital training platform for psychiatry residents in IPT for depression treatment.
Aim 1. What is the feasibility of an asynchronous self-directed online digital training platform? To assess feasibility, we will examine psychiatric resident recruitment, and participation (completion of the online modules and homework assignments) for the intervention condition vs control (synchronous large group online workshop).
Aim 2. What is the acceptability of the asynchronous self-directed online digital training process and platform? We will assess acceptability by conducting a process evaluation; this will take the form of semi-structured interviews with all residents in the intervention to explore experiences of learning through the asynchronous self-directed online curriculum and platform along with facilitators and barriers to attaining the learning objectives of achieving competency in delivering IPT.
Aim 3. Does the asynchronous self-directed online training platform demonstrate preliminary efficacy when training PGY 2-5 psychiatry residents in IPT for depressed patients, as compared to a synchronous large group online workshop? This will be estimated by assessing changes in patient outcomes of depressive symptoms over the course of treatment. A secondary patient outcome will be changes in patient anxiety symptoms over the course of IPT treatment. In addition, therapist-related outcomes will be assessed including therapeutic alliance, therapy quality as assessed by IPT- specific skills and non-specific therapeutic communication skills, IPT-knowledge, and counseling self-efficacy.
Target Population
The target population are psychiatry residents in good standing with the University of Toronto (UofT), Faculty of Medicine, post-graduate psychiatry residency program, all of whom require training in IPT as part of the residency requirements, and their IPT patients. Specifically, this will include psychiatry residents from four UofT-affiliated hospitals, Mount Sinai Hospital (MSH), Women's College Hospital (WCH), Sunnybrook Health Sciences Centre (SHSC) and the Centre for Addition and Mental Health (CAMH).
Study Design
This is a mixed-methods feasibility and acceptability study, with a single blind randomized controlled design comparing asynchronous self-directed digital IPT training to a synchronous large group online IPT workshop. Patients will be blind to therapist study arm allocation.
Procedure
Residents doing clinical rotations at MSH, SHSC,WCH and CAMH as part of their Psychiatry Residency training at the University of Toronto will be approached for consent by the Research Coordinator (RC) at the beginning of each academic semester. Consenting resident participants will complete a measure of their counseling self-efficacy and IPT knowledge before randomization to the intervention or the control condition, stratified by study site (MSH, WCH, SHSC and CAMH). Patient recruitment will be through referrals via treatment providers at all study sites (MSH, SHSC, WCH, and CAMH). Patient participants will be stratified by site and then randomly assigned to residents in the intervention or control condition.
Resident participants will be randomized to one of two training conditions: (1) synchronous self-directed digital training (intervention condition), where residents will complete an interactive modular curriculum covering evidence-based psychotherapy principles and IPT-specific principles and strategies at their own pace over a two week time period; or (2) a synchronous online training workshop (control condition), which will involve the same content contained in the asynchronous self-directed digital training platform, except delivered over a one day online workshop.
Immediately after training has been completed, each resident participant will participate in structured role plays designed to assess the resident's competence on IPT-specific and general psychotherapy skills, as rated by two IPT experts. Resident participants will then begin their 12-week course of therapy with their assigned patient participant. During treatment delivery, residents will have once weekly one-on-one supervisory sessions with an IPT expert supervisor/faculty member of the University of Toronto, Department of Psychiatry, who will be blind to residents' foundational didactic training modality.
Patient participants will complete measures of their depressive and anxiety symptoms just before each weekly session, as well as a measure of therapeutic alliance at the 3rd and final therapy sessions. At every session resident participants will complete a measure of their impression of their patient's improvement (or lack thereof) as well as a measure of therapy quality. They will complete the measures of counseling self-efficacy and IPT knowledge at the conclusion of the course of therapy with their patient. Consenting resident-patient pairs will audio record each therapy session; these recordings will be transcribed and coded for therapy quality. Resident participants randomized to the intervention condition (asynchronous digital training) will complete a semi-structured interview exploring the barriers and facilitators to engaging with the digital training platform in order to assess the acceptability of the intervention.
