The present research study will evaluate the feasibility and preliminary efficacy of the adapted Building Regulation in Dual Generations program for families of children (8-12 years old) with Attention-Deficit/Hyperactivity Disorder, creating the BRIDGE-ADHD program. The BRIDGE-ADHD program combines 10 weekly online psycho-education sessions with knowledge about ADHD and relevant parenting skills training videos to improve maternal wellbeing and parenting practices, thus supporting children's own psychological wellbeing through an intergenerational approach. This study will specifically evaluate whether the BRIDGE-ADHD program is able to reduce mothers' psychological distress (e.g., depression, anxiety, parenting stress) and simultaneously reduce their children's attention and/or behaviour problems.
Families of children with attention-deficit/hyperactivity disorder (ADHD) often experience elevated parenting stress. Maternal psychological distress (e.g., symptoms of depression and anxiety) is associated with harsher parenting practices that may increase children's risk for both externalizing and internalizing behaviour problems, including ADHD symptoms such as hyperactivity, impulsivity, and inattention. ADHD is in turn associated with deficits in self-regulation and executive functioning, which tend to result in social and academic difficulties that negatively impact the lives of children and families.
Supporting parents through effective parenting strategies is a key modifiable factor that can reduce child behavioural difficulties. Improving parent mental health by reducing parenting stress through skills-based parenting and psychoeducation may reduce parental distress and improve family functioning.
The Building Regulation in Dual Generations program (BRIDGE) for ADHD program is designed to provide mothers with mental health support and parenting skills that promote more effective management of their child's ADHD symptoms and, ultimately, reduce attention and behaviour problems through improvements in self-regulation. BRIDGE-ADHD is an adapted 10 week program that aims to support intergenerational emotion regulation and positive parenting strategies. The program combines dialectical behaviour therapy (DBT) skills with parenting-focused psychoeducational content. Each week, participants will attend a 1.5 hour synchronous online group session led by a licensed clinical psychologist, co facilitated by clinical psychology graduate students under supervision, and a peer parent coach who has previously participated in the BRIDGE program.
This study will use a non-randomized, parallel-assignment feasibility pilot design to evaluate the feasibility and potential efficacy of BRIDGE-ADHD in addressing parenting stress and children's attentional and behavioural problems. We will recruit thirty parent-child dyads (15 intervention participants and 15 normative controls). Participants in the intervention group will complete the 10 week online BRIDGE-ADHD program and in person assessments at two time points: pre intervention (week 0-1; T0) and post intervention (week 10; T1). The normative control group will complete the same in person assessments without participating in the intervention. The primary aim is to examine the feasibility and acceptability of BRIDGE-ADHD and its impact on maternal mental health and children's social-emotional development.
Secondary aims are to evaluate the program's efficacy in reducing parenting stress and decreasing harsh parenting tendencies. Exploratory aims include examining differences or changes in sleep quality, mental well-being, relationships, and child academic achievement before and after participation in BRIDGE-ADHD.

Changes in child mental health symptoms following BRIDGE-ADHD intervention
Changes in child mental health symptoms will be measured using the Child Behavior Checklist (CBCL) for ages 6 to 18. The CBCL is a 100-item parent-report questionnaire with a range of scores from 0 to 200, measuring child functioning across externalizing and internalizing symptoms. All raw scores are converted into T-scores across all domains tested to have a standardized outcome. Higher T-scores indicate greater symptom severity. We will use the CBCL to assess a) total behaviour problems, b) ADHD subscale scores, c) internalizing behaviours, and d) externalizing behaviours. These subscale scores will collectively be investigated as child mental health symptoms.
Time frame: This measure will be administered at baseline, (week 0-1; noted as T0) and after 10 weeks of BRIDGE intervention, post-intervention which will occur between weeks 11-12 (noted as T1).
Changes in maternal depressive symptoms
Depressive symptoms will be measured using the Patient Health Questionnaire 9-Item (PHQ-9). The PHQ-9 is a 9-item self-report questionnaire with a range of scores from 0 to 27. Higher scores indicate greater symptom severity.
Time frame: This measure will be administered at baseline, which is considered week 0-1 (noted as T0) and after 10 weeks of BRIDGE intervention, post-intervention taking place at weeks 11-12 ( noted as T1).
Maternal ratings of program acceptability
Maternal ratings of program acceptability will be collected using an open-ended program acceptability questionnaire developed by the research team. Participants will rate how important various components of the program were to them and will be asked to respond to open-ended questions regarding their experience in the program.
Time frame: This measure will be administered after the 10 week of BRIDGE intervention, post-intervention (noted as T1) expected to take place sometime between weeks 11-12.
Recruitment Feasibility Metrics
