Behavioral activation to prevent depression in at-risk adolescents: A pilot feasibility, acceptability and potential impact trial
Bibliographic record
Abstract
This study aimed to assess the feasibility, acceptability, and potential impact of a novel 5-week group Behavioral Activation (BA) prevention program for adolescents at risk of depression. A pilot study with a pre-post design was conducted on one group of adolescents ( N = 9) with depressive symptoms in a high school setting. The nonparametric Wilcoxon signed-rank test was conducted to determine potential impact of the program on depressive symptomatology, the incidence of depressive diagnoses and behavior change from pretest to posttest. Feasibility and acceptability were established by the active participation, low drop-out rate, and positive comments collected. As for the potential impact of the program, significant pre-post differences suggest improvement in participants who initially presented with subclinical depressive symptoms. Participants enjoyed the activities they were participating in, despite an overall reduction in the number and variety of activities that were possible due to the pandemic lockdown. Also, the participants expressed an improvement in their functioning. The group BA prevention program for at-risk adolescents appears feasible, acceptable, and effective within a school setting. A larger controlled trial is needed to confirm its efficacy and determine the clinical significance of BA as a preventive intervention for adolescent depression.

How this classification was reachedexpand
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.
