Adaptive changes in infant emotion regulation persist three months following birthing parent receipt of cognitive behavioral therapy for postpartum depression
Bibliographic record
Abstract
Infants exposed to postpartum depression (PPD) exhibit more emotion regulatory (ER) difficulties than infants who are not. While treatments for PPD that include cognitive behavioral therapy (CBT) may adaptively alter infant ER immediately following treatment, it is unclear if these improvements persist. This study examined if adaptive changes in infant ER persisted three months after their birthing parent completed 9-weeks of CBT for PPD. We used data from n = 35 case infants (of birthing parents diagnosed with a postpartum major depressive disorder), and n = 33 healthy control infants (born to non-depressed birthing parents and matched to case infants on age, sex and family SES). A multimethod assessment of infant ER included resting-state frontal EEG asymmetry (FA), high-frequency heart rate variability (HF-HRV), and birthing parent- and partner-reported temperamental positive affect (PA). Infant ER was examined at three study visits (V1 occurred before CBT/at baseline for control infants, V2 took place immediately after CBT (9-weeks later), and V3 was three months after V2). Three months after birthing parent CBT (V3), infants continued to exhibit greater left FA relative to pre-treatment [∆mean V1 to V3 = 0.19, [SE = 0.082], p = 0.02]-the pre-to-post treatment shift from right to left FA remained statistically significant at V3). HF-HRV at V3 also increased relative to pre-treatment [∆m V1 to V3 = 0.81, [0.19], p < 0.001], as did PA reported by birthing parents [∆m V1 to V3 = 0.64, [0.16], p < 0.001] and their partners [∆m V1 to V3 = 0.54, [0.18], p = 0.004]. No ER measures differed between case and control infants at the three-month visit. Treating PPD may set infants on a persistent adaptive ER trajectory. • Maternal postpartum depression (PPD) predicts infant emotion regulation problems. • Treating PPD alters behavioral and biological markers of infant emotion regulation. • Adaptive infant emotion regulation changes persist 3 months following treatment. • PPD treatments may set infants on a more adaptive developmental trajectory.

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.
