Parental sleep patterns and variability at 6 months postpartum: Associations with family factors and depressive symptoms
Bibliographic record
Abstract
Changes in sleep are among the most significant adjustments parents experience in the postpartum period.To date, most research on postpartum sleep has focused on maternal sleep patterns, including the link between maternal sleep disturbances and postpartum mood.Although sleep is a family process, fathers remain frequently overlooked in the literature and less is known about paternal postpartum sleep patterns.The aim of the present dissertation was to advance our knowledge about typical sleep patterns and variability in both mothers and fathers at 6 months postpartum, and to examine the links between parents' sleep and familial and psychosocial factors.Study 1 described and compared sleep patterns and intraindividual night-to-night variability in both parents (N = 33 couples) at 6 months postpartum.A multi-measure approach was used to measure parental sleep, consisting of subjective (i.e., daily sleep diary) and objective (i.e., actigraphy) indices, over the course of 10 consecutive nights.Additionally, associations between parental sleep and specific family factors, including age, education level, employment status, number of children, infant feeding method, infant sleep location, and infant nocturnal sleep variables were investigated.Study 2 examined the relationship between sleep and depressive symptoms at 6 months postpartum, exclusively in fathers (N = 54) as they represent an important, understudied population.Paternal sleep was assessed over the course of 2 weeks utilizing subjective (i.e., daily sleep diary and self-reported perceived sleep quality) and objective (i.e., actigraphy) indices, whereas paternal depressive symptoms were measured using the Center for Epidemiologic Studies -Depression Scale (CES-D).The association between fathers' sleep patterns and depressive symptoms was assessed while controlling for individual and family factors.for the development of clinical interventions targeting paternal sleep and mood in the postpartum period.

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.
