Researchers compared three training pathways: self-directed digital training (DGT), digital training plus remote coaching (DGT+), and traditional face-to-face classroom-based training (F2F). Participants were randomly assigned to one of the arms and completed a knowledge assessment before and after training. The primary outcome focused on learning gains, quantified as changes in knowledge scores, rather than direct clinical outcomes.

Completion rates were high across all groups, with 87% finishing DGT, 96% completing DGT+, and 92% completing F2F. Knowledge scores improved in every arm, indicating that all training formats can build core competency related to behavioral activation. Notably, F2F and DGT+ produced comparable improvements, suggesting that adding coaching to digital instruction can narrow the gap often seen when trainees learn remotely.

The self-directed digital approach (DGT) performed worse than the classroom method, but the difference was not statistically decisive: the reported P value was 0.077. In practical terms, DGT still delivered meaningful learning, though it may require enhancements to match the effectiveness of coached or in-person formats.

Beyond effectiveness, the trial evaluated cost-effectiveness—an essential metric for scaling mental health programs. Average per-participant costs were highest for F2F at US$209.26, intermediate for DGT+ at US$150.42, and lowest for DGT at US$121.24. Cost-effectiveness analyses indicated that digital strategies become more favorable at lower willingness-to-pay thresholds.

Taken together, the results support a scalable and lower-cost training pipeline, especially when digital modules are paired with remote coaching. The authors caution, however, that knowledge improvements must be translated into real-world clinical competency and effective patient care—an open question for future research.
