Protocol for a randomized control trial of the Building Regulation in Dual Generations Program (BRIDGE): preventing the intergenerational transmission of mental illness in at-risk preschool children
Bibliographic record
Abstract
BACKGROUND: Since the onset of the COVID-19 pandemic, the worldwide prevalence of maternal depression has risen sharply; it is now estimated that one quarter of mothers experience clinically significant depression symptoms. Exposure to maternal depression during early childhood increases the risk for the development of childhood mental illness (MI) in offspring, with altered parenting practices mediating the association between maternal depression and child outcomes. Dual-generation interventions, which aim to simultaneously treat parent and child mental health, show promise for improving outcomes for mothers with depression and their young children. The Building Regulation in Dual Generations (BRIDGE) program combines Dialectical Behavior Therapy (DBT) and parenting skills training to concurrently treat maternal depression and improve parenting practices. In pilot within-group studies, BRIDGE has led to large reductions in maternal depression and child MI symptoms. The aim of the current study is to evaluate the efficacy of BRIDGE in reducing maternal depression and child MI symptoms (primary outcomes) as well as parenting stress and harsh parenting (secondary outcomes). METHODS: A three-armed randomized control trial with equal group sizes will be conducted to compare the efficacy of (1) BRIDGE (DBT + parenting skills), (2) DBT skills training, and (3) services-as-usual. Participants (n = 180) will be mothers of 3- to 5-year-old children who report elevated depression symptoms. Those randomized to BRIDGE or DBT skills training will complete a 16-week group therapy intervention. Assessments will be administered at pre-intervention(T1) post-intervention (T2), and 6-month follow-up (T3). DISCUSSION: Dual-generation programs offer an innovative approach to prevent the intergenerational transmission of mental illness. The current study will add to the evidence base for BRIDGE by comparing it to a stand-alone mental health intervention and a services-as-usual group. These comparisons will provide valuable information on the relative efficacy of including parenting support in a mental health intervention for parents. The results will contribute to our understanding of how maternal depression affects children's development and how intervening at both a mental health and parenting level may affect child and family outcomes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
