Effectiveness of a parent "buddy" program for mothers of very preterm infants in a neonatal intensive care unit.
Bibliographic record
Abstract
OBJECTIVE: Very preterm birth (< 30 weeks' gestation) is a stressful event for parents, and few support interventions for these parents have been evaluated. In this study, we evaluated the effectiveness of parent-to-parent peer support for mothers of very preterm infants in a neonatal intensive care unit (NICU). METHODS: In this cohort study, 32 mothers were recruited for the intervention group from the Mount Sinai Hospital and 28 mothers were recruited for the control group from the Sunnybrook and Women's College Health Sciences Centre, both located in Toronto. The NICUs of these hospitals serve the same region and accept referrals on alternate days. Mothers in the intervention group were paired with trained mothers who had previously had a very preterm infant in the NICU and who provided principally telephone support. Participants in both groups received standard medical and social work services. Primary outcome data consisted of self-reported, standardized measures of parental stress, state anxiety and depression. Secondary measures included self-reported, standardized measures of perceived social support and trait anxiety. RESULTS: At 4 weeks after enrolment in the study, mothers in the intervention group reported less stress than those in the control group (mean score 1.54 v. 2.93, p < 0.001). At 16 weeks after enrolment, the intervention group reported less state anxiety (mean score 31.4 v. 38.6, p < 0.05), less depression (mean score 2.20 v. 4.88, p < 0.01) and greater perceived social support (mean score 6.49 v. 5.48, p < 0.01) than the control group. There was no difference between the groups in terms of trait anxiety. Of the 24 mothers who evaluated the program, 21 (87.5%) indicated that it was very helpful or helpful. INTERPRETATION: Support from individual, trained peers was found to be effective in helping mothers deal with the stress of very preterm birth.

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.
