This study focused on attachment of foster children by examining factors associated with attachment relationships of children raised from birth by the same parents. The sample included 61 children between 26 to 88 months of age and their foster caregivers. Attachment security and caregiver sensitivity were coded on the basis of, respectively, a(More)
Infant temperamental characteristics have been found associated with decreasing parenting self-efficacy (PSE) during the first year after birth, which has been generally interpreted as a child effect on the parent. To test direction of effects, PSE was assessed during the third trimester of pregnancy and twice after birth together with perceived infant(More)
This study examined whether the quality of relationships with foster caregivers was associated with autonomic nervous system reactivity of children during separation and reunion with their foster caregiver. Moreover, effects of early adversity were examined in relation to attachment and autonomic nervous system reactivity. The sample included 60 children(More)
Twenty years ago, meta-analytic results (k = 19) confirmed the association between caregiver attachment representations and child-caregiver attachment (Van IJzendoorn, 1995). A test of caregiver sensitivity as the mechanism behind this intergenerational transmission showed an intriguing "transmission gap." Since then, the intergenerational transmission of(More)
OBJECTIVE To determine whether foster children showed different autonomic nervous system activity on separation and reunion than control children. Autonomic nervous system activity in foster children was examined in relation to time in placement and disinhibited attachment. METHOD The sample included 60 foster and 50 control children between 2 and 7 years(More)
This study examined physiological effects of separation and reunion in a sample 3- to 6-year-old children. Using continuous ambulatory recording, changes in heart rate (HR), respiratory sinus arrhythmia (RSA), and pre-ejection period (PEP) were compared across the episodes of a separation-reunion procedure based on the strange situation. RSA decreased(More)
BACKGROUND High levels of prenatal maternal anxiety - either pregnancy-specific anxiety or general anxiety - may have detrimental effects on both the mother and her child. It is currently unknown how these two different expressions of anxiety influence each other over time during pregnancy. AIMS This study aimed to describe the relationship between state,(More)
BACKGROUND Previous DSM-versions recognized an inhibited and a disinhibited subtype of the Reactive Attachment Disorder (RAD). The current DSM-5 distinguishes two different disorders, instead of two subtypes of RAD. This study examined whether a split-up of the subtypes is valid. METHOD In 126 foster children, attachment disorder symptoms were assessed(More)
The aim of the study was to examine parenting self-efficacy in relation to depressive and anxiety symptoms during pregnancy. Five hundred thirty-three first-time pregnant women completed questionnaires at 12, 22, and 32 weeks of pregnancy that measure parenting self-efficacy, anxiety, and depressive symptoms. Parenting self-efficacy increased slightly but(More)
OBJECTIVES A clear association between exposure to intimate partner violence (IPV) and children's physical health is still not well determined, because adverse effects might be explained by the confounding detrimental effects of other traumatic experiences. This study investigated whether children exposed to IPV have higher risks for physical health(More)
