The Selah trial: A preference-based partially randomized waitlist control study of three stress management interventions
Bibliographic record
Abstract
ABSTRACT Objective Chronic stress can undermine psychological and physiological health. We sought to evaluate three stress management interventions among clergy, accounting for intervention preferences. Methods United Methodist clergy in North Carolina enrolled in a partially randomized, preference-based waitlist control trial. The interventions were: mindfulness-based stress reduction (MBSR), Daily Examen prayer practice, and Stress Proofing (stress inoculation plus breathing skills). The intervention period spanned 12 weeks with a 12-week follow-up. Daily text message data were collected to assess practice across the 24 weeks. Co-primary outcomes were symptoms of stress using the Calgary Symptoms of Stress Inventory and 48-hour ambulatory heart rate variability (HRV) at 12-weeks post-intervention compared to waitlist control. Survey data were collected at 0, 12 and 24 weeks, with HRV collected at 0 and 12 weeks. Results 255 participants (mean age=54 years old; 91% white; 48% female) were randomized and initiated an intervention (n=184) or waitlist control (n=71). Compared to waitlist control, lower stress symptoms were found for MBSR participants [Mean Difference (MD)=-0.30, 95% CI:-0.41,-0.20; p <.001] and Stress Proofing (MD=-0.27, 95% CI:-0.40,-0.14; p <.001) at 12 weeks, and Daily Examen participants not until 24 weeks (MD=-0.24, 95% CI:-0.41,-0.08). Only MBSR participants demonstrated improvement in HRV at 12 weeks (MD=+3.32 millisecond; 95% CI:0.21,6.44; p =.036). Conclusions MBSR demonstrated robust improvement in self-reported and objective physical correlates of stress whereas Stress Proofing and Daily Examen resulted in improvements in self-reported correlates of stress only. These brief practices were sustainable and beneficial for an occupational sample during the COVID pandemic.

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.
