Ontario Brain Injury Association Peer Support Program: a mixed methods protocol for a pilot randomised controlled trial
Bibliographic record
Abstract
INTRODUCTION: The objective of this study is to conduct a pilot randomised controlled trial (RCT) of the Ontario Brain Injury Association (OBIA) Peer Support Program. The RCT is designed to evaluate the effectiveness and dose-response of the Peer Support Program in improving participation and mood for people with moderate-to-severe traumatic brain injury compared with a wait-list control group. METHODS AND ANALYSIS: The proposed research is a three-phase, mixed methods pilot RCT. Consistent with an integrated knowledge translation approach, the study design has been informed in consultation with the knowledge user (ie, OBIA). It will include an initial qualitative examination of barriers and enablers to the trial implementation (phase 1), a pilot RCT (phase 2) and conclude with a qualitative component (phase 3). A qualitative descriptive approach will be adopted for both qualitative phases of the study (n=20-25) and thematic analysis will be used. The 6 months phase-2 trial will be conducted with 60 participants. These participants will be randomised to one of three groups: a twice a week programme (n=20), a once a week programme (n=20) or the wait-list control group (n=20). The feasibility of participant recruitment and retention, data collection, as well as participant adherence to the OBIA Peer Support Program will be evaluated. The primary outcome measure will be participation, as measured by the Participation Assessment with Recombined Tools-Objective. Other proposed outcomes of interest will include mood, health-related quality of life and self-efficacy. ETHICS AND DISSEMINATION: Ethics approval will be obtained from the principal author's institution (University Health Network Research Ethics Board). The results of this study will inform the development of a larger scale RCT and will inform future iterations of the OBIA Peer Support Program including a revised programme curriculum. TRIAL REGISTRATION NUMBER: NCT03450460; Pre-results.

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.
