A longitudinal study of the links between maternal and infant nocturnal wakefulness.

Study Objectives: To examine the longitudinal links between maternal and infant nocturnal wakefulness by employing a trajectory-based approach, and to assess whether the strength of these links differs as a function of sleep assessment method (actigraphy vs. self-report) and sleeping arrangements.

Methods: Maternal and infant nocturnal wakefulness were assessed with actigraphy and sleep diaries at home for 5 nights, at 3 (N = 191), 6 (N = 178), 12 (N = 155), and 18 (N = 135) months postpartum.

Maternal emotional distress and infant sleep: A longitudinal study from pregnancy through 18 months.

This longitudinal study examined whether changes in maternal emotional distress (depressive, anxiety, and parenting-stress symptoms) predict changes over time in subjective and objective infant sleep. We recruited 226 Israeli expectant mothers ( age 28.8 ± 3.

Prenatal maternal sleep and trajectories of postpartum depression and anxiety symptoms.

Postpartum emotional distress is very common, with 10%-20% of postpartum women reporting depressive or anxiety disorders. Sleep is a modifiable risk factor for emotional distress that has a pivotal role in postpartum adjustment. The present study aimed to examine whether sleep duration and quality during pregnancy predict trajectories of emotional distress in the postpartum period.

Mother-Infant Sleep and Maternal Emotional Distress in Solo-Mother and Two-Parent Families.

Objective: This study examined for the first time mother-infant sleep and emotional distress in solo mother families compared with two-parent families and explored whether the links between mother-infant sleep and maternal emotional distress differ as a function of family structure.

Methods: Thirty-nine solo-mother families and 39 two-parent families, with an infant within the age range of 6-18 months participated in the study. Actigraphy and sleep diaries were used to assess maternal and infant sleep at home.

Infant nocturnal wakefulness: a longitudinal study comparing three sleep assessment methods.

Study Objectives: To examine the convergence between actigraphy, sleep diaries, and the Brief Infant Sleep Questionnaire (BISQ) in the assessment of infant nocturnal wakefulness (i.e. minutes awake after sleep onset [WASO] and number of night-wakings [NW]) in the context of a longitudinal study.

Links between infant sleep and parental tolerance for infant crying: longitudinal assessment from pregnancy through six months postpartum.

Background: Low parental tolerance for crying has been associated with infant sleep problems, yet the directionality of this link remained unclear. This longitudinal study aimed to assess the synchronous and prospective bidirectional links between parental cry-tolerance, soothing, and infant sleep from pregnancy through six months postpartum.

Methods: Sixty-five couples were recruited during pregnancy and assessed for cry-tolerance using a paradigm in which participants were shown a videotape of a crying infant and were asked to stop the video when they feel it is necessary to intervene.

Mother-infant sleep patterns and parental functioning of room-sharing and solitary-sleeping families: a longitudinal study from 3 to 18 months.

Study Objectives: To examine longitudinally differences in (1) objective and subjective sleep patterns and (2) parenting functioning (i.e. maternal emotional distress, maternal separation anxiety, and parental involvement in infant care) between room-sharing and solitary-sleeping mother-infant dyads.

Sleep patterns of co-sleeping and solitary sleeping infants and mothers: a longitudinal study.

Objective: Controversies exist regarding the impact of co-sleeping on infant sleep quality. In this context, the current study examined: (a) the differences in objective and subjective sleep patterns between co-sleeping (mostly room-sharing) and solitary sleeping mother-infant dyads; (b) the predictive links between maternal sleep during pregnancy and postnatal sleeping arrangement; (c) the bi-directional prospective associations between sleeping arrangement and infant/maternal sleep quality at three and six months postpartum.

Methods: The sample included 153 families recruited during pregnancy.

Objective and subjective sleep during pregnancy: links with depressive and anxiety symptoms.

The aims of this paper are to study the associations between objective and subjective sleep in pregnant women, to examine which specific aspects of women's sleep are associated with depressive and anxiety symptoms and to test the moderating role of depressive and anxiety symptoms in the relations between objective and subjective sleep. The sample included 148 pregnant women. Objective sleep was measured by actigraphy for five nights at the participants' home, and subjective sleep was measured with the Pittsburgh sleep quality index.

Infant sleep development from 3 to 6 months postpartum: links with maternal sleep and paternal involvement.

The aims of this longitudinal study were to examine (a) development of infant sleep and maternal sleep from 3 to 6 months postpartum; (b) concomitant and prospective links between maternal sleep and infant sleep; and (c) triadic links between paternal involvement in infant caregiving and maternal and infant sleep. The study included 57 families that were recruited during pregnancy. Maternal and infant sleep was assessed using actigraphy and sleep diaries for 5 nights.
