About this trial
The goal of this feasibility study is to learn whether a trauma therapy intervention for children and adolescents who have experienced weight-based bullying can be successfully delivered within a pediatric weight management program. The intervention is informed by Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) principles and is designed to address trauma-related distress, body image concerns, emotional difficulties, and eating-related challenges associated with weight-based bullying. The main questions this study aims to answer are:
* Can this trauma therapy intervention be feasibly implemented within the HEAL Program at Children's Hospital, London Health Sciences Centre? * Is the intervention acceptable and helpful for participating children, adolescents, and caregivers? * Are exploratory changes observed in trauma symptoms, emotional well-being, self-esteem, eating-related concerns, and weight-related distress following participation in the intervention?
Participants will:
* Participate in approximately 12 weekly virtual therapy sessions, with flexibility for additional sessions if clinically needed * Complete questionnaires before and after treatment related to emotional well-being, trauma symptoms, eating-related concerns, and body image * Participate in selected caregiver-supported sessions during treatment * Optionally complete a brief feedback interview about their experience in the program after treatment is completed
The study will also examine recruitment, attendance, treatment completion, and participant satisfaction to help determine whether this intervention can be implemented in routine clinical care settings.

Trauma Therapy for Weight-Based Bullying Informed by TF-CBT
BehavioralThis intervention is a trauma therapy program for children and adolescents experiencing distress related to weight-based bullying. The intervention is informed by the core principles and components of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and is adapted to address bullying-related trauma, body image concerns, emotional distress, maladaptive eating behaviours, and weight-related stigma. The intervention includes psychoeducation, emotional regulation and coping skills, cognitive coping strategies, trauma narrative development and processing, body image and stigma-related cognitive restructuring, caregiver support strategies, and safety planning as clinically indicated. Treatment is developmentally tailored and delivered virtually within the HEAL Program at Children's Hospital, London Health Sciences Centre. Participants will complete approximately 12 weekly therapy sessions delivered by a trained MSW/RSW clinician.
Treatment groups
Trial outcomes
Primary outcomes
Outcome Measure 1: Recruitment Rate
Recruitment rate, defined as the proportion of eligible participants who consent and enroll in the study.
Outcome Measure 2: Session Attendance
Session attendance, defined as the number and proportion of intervention sessions attended by each participant during the intervention period.
Outcome Measure 3: Retention Rate
Retention rate, defined as the proportion of enrolled participants who complete the post-treatment assessment.
Outcome Measure 4: Treatment Completion Rate
Treatment completion rate, defined as the proportion of participants who complete at least 10 of the 12 intervention sessions.
Secondary outcomes
Outcome Measure 7: Trauma-Related Symptoms
Exploratory changes in trauma-related symptoms will be assessed using the Children's Revised Impact of Event Scale-13 (CRIES-13). Total scores range from 0 to 65, with higher scores indicating greater trauma-related symptom severity.
Outcome Measure 8: Anxiety Symptoms
Exploratory changes in anxiety symptoms will be assessed using the Generalized Anxiety Disorder-7 (GAD-7). Total scores range from 0 to 21, with higher scores indicating greater anxiety symptom severity.
Outcome Measure 9: Depressive Symptoms
Exploratory changes in depressive symptoms will be assessed using the Patient Health Questionnaire-9 (PHQ-9). Total scores range from 0 to 27, with higher scores indicating greater depressive symptom severity.
Outcome Measure 10: Weight Bias Internalization
Exploratory changes in weight bias internalization will be assessed using the Weight Bias Internalization Scale-Modified (WBIS-M). Mean scores range from 1 to 7, with higher scores indicating greater internalized weight bias.
