OA15.02. Quantitative findings from piloting the LEAP project: an online spirituality based depression intervention for young adults
Bibliographic record
Abstract
This pilot study used a parallel-group randomized controlled assessor-blinded trial design. A total of 46 individuals aged 13-24 with clinically diagnosed unipolar major depression of mild to moderate severity are being recruited in Calgary, Canada and randomized to two study arms: 1. Immediate Intervention Group (eight week online intervention) and 2. Waitlist Control Group (no intervention for 8 weeks followed by the online intervention). Participants were assessed at baseline, 8, 16 and 24 weeks. The main outcome measure (depression severity) was based on the Children Depression Rating Scale (CDRS for participants aged 13 to 18) and the Hamilton Depression Rating Scale (HAM-D for participants aged 19-24). Preliminary analysis of 30 participants (20 participants aged 13-18, 10 participants aged 19-24) indicates notable changes in depression severity at 8 weeks in the Immediate Intervention Group compared to the Waitlist Control Group. For those aged 13-18 in the Immediate Intervention Group the CDRS score change at 8 weeks was -13.8 compared to -1.8 in the Waitlist Control Groups (p=0.044). Follow-up scores for this group at 16 and 24 weeks show a further reduction in depression severity compared to the baseline score (CDRS score change at 16 weeks: -21.6 and at 24 weeks: -23.3). For those aged 19-24 in the Immediate Intervention Group the HAM-D score change at 8 weeks was -8.8 compared to -3.6 in the Waitlist Control Groups (p=0.037); 16 and 24 week follow-up scores suggest that the post intervention score was maintained. Preliminary results suggest that the LEAP Project can reduce depression severity long term. Data collection is continuing and final results will be available for presentation in May 2012.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
