OBJECTIVE To determine if maladaptive parental behaviors (at age 29-41 months) and mother/child psychological characteristics predict future sleep disturbances in 50-month-old to 6-year-old preschoolers, while controlling for early (age 5-17 months) sleep and sociodemographic factors. DESIGN Randomized survey; children assessed annually from 5 months to 6(More)
STUDY OBJECTIVES To (1) clarify the epidemiology of bad dreams in children and investigate risk and protective factors related to (2) the child's sleep, (3) parental sleep-enabling practices, and (4) the child's temperament. DESIGN Longitudinal with 6 time points from 5 months to 6 years. SETTING Subjects' homes. PARTICIPANTS Representative sample of(More)
OBJECTIVE The majority of women develop sleep impairments during pregnancy, but alterations in dream experiences remain poorly understood. This study aimed to assess prospectively and comparatively the recall of dreaming and of disturbed dreaming in late pregnancy. METHODS Fifty-seven nulliparous, third-trimester pregnant women (mean age±SD, 28.7±4.06(More)
OBJECTIVES To examine the relation between early maladaptive schemas (EMS), as defined in schema therapy, and both child and adult attachment. DESIGN A 15-year longitudinal design in which child attachment groups (secure, avoidant, ambivalent, and disorganized) were compared in early adulthood on their profile of scores across EMS domains. A similar(More)
Isolated sleep paralysis (ISP) is a common parasomnia characterized by an inability to move or speak and often accompanied by hallucinations of a sensed presence nearby. Recent research has linked ISP, and sensed presence more particularly, with social anxiety and other psychopathologies. The present study used a large sample of respondents to an internet(More)
Dreams are thought to respond to self- and socially-relevant situations that evoke strong emotions and require rapid adaptation. First pregnancy is such a situation during which maternal mental representations (MMR) of the unborn baby, the self and significant others undergo remodeling. Some studies suggest that dreams during pregnancy contain more MMR and(More)
STUDY OBJECTIVES The algorithms used to derive sleep variables from actigraphy were developed with adults. Because children change position during sleep more often than adults, algorithms may detect wakefulness when the child is actually sleeping (false negative). This study compares the validity of three algorithms for detecting sleep with actigraphy by(More)
OBJECTIVE To investigate relations between children's attachment and sleep, using objective and subjective sleep measures. Secondarily, to identify the most accurate actigraphy algorithm for toddlers. METHODS 55 mother-child dyads took part in the Strange Situation Procedure (18 months) to assess attachment. At 2 years, children wore an Actiwatch for a(More)
This study investigated the moderating role of infant sleep in the connections between maternal sensitivity and three indicators of infant functioning: attachment security, theory of mind, and executive functioning (EF). Maternal sensitivity was assessed when infants (27 girls and 36 boys) were 1 year of age. Infant sleep was assessed with actigraphy at age(More)
This study investigated the effectiveness of a psychotherapeutic treatment for nightmares that was adapted for 6- to 11-year-old children from imagery rehearsal therapy. Ten child-mother dyads took part in a 3-session, 8-week treatment protocol. Participation in the study (contact with clinician, keeping a prospective dream log) was associated with(More)
