A pilot randomized controlled trial of a lay telephone coaching and web-based intervention for postpartum depression and anxiety: The MPOWER study
Bibliographic record
Abstract
Background: Mental health problems are frequent in the postpartum period, but accessible treatment options are lacking. The MPOWER study investigated whether the use of trained lay coaches could increase the uptake and effectiveness of a web-based intervention (WBI) for women with postpartum depression and/or anxiety. Objectives: First, to compare the feasibility and acceptability of a WBI for women with postpartum depression and anxiety, with and without the addition of telephone coaching calls. Second, to estimate the effectiveness of the WBI at decreasing symptoms of depression and anxiety at 6 months, with and without coaching calls. Methods: We conducted a pilot randomized controlled trial (RCT) that enrolled women who had recently given birth and had mild to moderate postpartum depression and/or anxiety. Study participants were provided access to the WBI. Women randomized to the intervention group also received up to 7 telephone coaching calls during the 6 months of follow up. We evaluated the feasibility of the intervention through participants' usage of the WBI, as well as the completion and fidelity of planned coach calls. We measured acceptability via two questionnaires on the usability of the WBI and participant satisfaction with the intervention. To determine the potential effectiveness of the intervention, the primary outcomes were defined as symptoms of depression and anxiety at 6 months and adjusted mean differences between groups for these outcomes were estimated using linear regression models. Results: We recruited 52 participants (25 intervention; 27 control). At 6 months, 88 % (22/25) of participants randomized to the intervention arm and 59 % (16/27) of participants randomized to the control arm remained in the study. The intervention group had an average of 11 (95 % CI: [5, 18]) more website logins than the control group. Intervention group participants completed a mean of 6.2 coaching calls with high fidelity. The estimates of the effect of the intervention on mental health outcomes at 6-months were imprecise but point estimates and confidence intervals were consistent with a moderate beneficial effect of the intervention on both symptoms of depression and anxiety (fully adjusted effects sizes: 0.51 (95 % CI: [-0.14, 1.17]) and 0.56 (95 % CI: [-0.09, 1.22]), respectively). Conclusions: WBIs with coaching are feasible, acceptable, and potentially effective treatment options for women with mild to moderate postpartum depression and/or anxiety. The addition of coaching calls markedly increased engagement with the WBI, but a larger RCT is needed to determine the effectiveness of such an intervention.

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.
