The Importance of Shared Environment in Infant-Father Attachment: A Behavioral Genetic Study of the Attachment Q-Sort.

In this first behavior genetic study on infant-father attachment, we estimated genetic and environmental influences on infant-father attachment behaviors and on temperamental dependency, both assessed with the Attachment Q-Sort (AQS; B. E.Vaughn & E. Waters, 1990; E. Waters, 1995). Mothers of mono- and dizygotic twins (N = 56 pairs) sorted the AQS with a focus on the infant's behaviors in the presence of the father. Genetic modeling showed that attachment was largely explained by shared environmental (59%) and unique environmental (41%) factors. For dependency, genetic factors explained 66% of the variance, and unique environmental factors including measurement error explained 34%. Attachment to father appears to be, to a significant degree, a function of the environment that twins share. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Supporting affect regulation in children with multiple disabilities during psychotherapy: A multiple case design study of therapeutic attachment.

In a controlled multiple case design study, the development of a therapeutic relationship and its role in affect regulation were studied in 6 children with visual disabilities, severe intellectual disabilities, severe challenging behavior, and prolonged social deprivation. In the 1st phase, children had sessions with an experimental therapist stimulating therapeutic attachment, alternating with a control therapist providing positive personal attention only. In the 2nd phase, both therapists applied behavior therapy. Clients sought more proximity to the experimental therapist compared with the control therapist. Psychophysiological arousal (respiratory sinus arrhythmia and pre-ejection period) was lower when the experimental therapist applied behavior modification than when the control therapist did. Despite prolonged social deprivation, the attachment behavioral system appeared responsive to stimulation. The effects on affect regulation may explain the synergy between psychotherapy based on interpersonal and behavior modification approaches.

In search of shared and nonshared environmental factors in security of attachment: A behavior-genetic study of the association between sensitivity and attachment security.

The current article presents results from a twin study of genetic and environmental components of maternal sensitivity and infant attachment and their association. The sample consisted of 136 twin pairs from 2 sites: Leiden, the Netherlands, and London, UK. Maternal sensitivity was assessed in the home at 9-10 months, and infant attachment security was observed in the laboratory at 12 months. The study yielded little evidence that genetic factors are involved in variations between twins in maternal sensitivity ratings but did find that shared variance in maternal sensitivity was able to account for some of the similarity between twins in attachment security. Weak nonshared associations between sensitivity and attachment appeared to suppress the magnitude of the correlation between attachment and sensitivity in twin children. The results could indicate that the attachment security of one twin may depend on the relationship the parent has with the other twin. The results are brought to bear on the validity of attachment theory as a theory of primarily shared environmental effects in children's development and the continuing challenge posed to attachment theory by within-family differences in socioemotional processes.

"Children of the dream" revisited: 70 years of collective early child care in Israeli kibbutzim.

This article focuses on kibbutz care for infants and young children. It reviews (1) past and present practices of collective education within the context of its historical background and guiding principles and (2) the results of developmental research regarding the impact of multiple caregiving and group care on children's socioemotional development within the framework of attachment theory. The research results indicate that, from a psychological point of view, collective sleeping is a problematic aspect of kibbutz child rearing. However, group care and multiple caregiving of high quality do not necessarily interfere with the formation of close relationships between parents and children or with the development of social skills.

Intergenerational family solidarity: Value differences between immigrant groups and generations.

Although immigrants may be more dependent on their immediate family for support, they may also experience a wider generation-gap in values regarding intergenerational solidarity, because of processes of acculturation. Based on large scale survey data (N = 2,028), differences between first and second generation immigrants in values regarding intergenerational solidarity were examined among family members in the Netherlands with an immigration background from Turkey, Morocco, Suriname, and The Dutch Antilles. Using a multilevel analytic approach, effects of family and individual characteristics on values regarding intergenerational solidarity were tested, considering the perspectives of two generations. It was found that immigrants with Moroccan and Turkish backgrounds scored higher on values with respect to intergenerational family solidarity than immigrants stemming from Suriname and The Antilles. First generation immigrants placed higher values on family solidarity compared to second generation immigrants. Additionally, religious denomination was a significant predictor of higher values with respect to intergenerational family solidarity. Immigration and acculturation may create great strains in migrant families. Policies to support the fabric of intergenerational solidarity should consider ethnic and religious background and immigration history.

Frightening maternal behavior linking unresolved loss and disorganized infant attachment.

Main and Hesse's (1990) model in which frightening (threatening, frightened, or dissociated) parental behavior explains why infants of parents with unresolved loss develop disorganized attachment relationships was tested. Unresolved loss using the Adult Attachment Interview in a nonclinical middle-class sample of 85 mothers who had experienced the loss of someone important was assessed. Disorganized attachment was examined in the Strange Situation. Parental behavior was recorded during 2 2-hr home visits. The model applied to mothers with currently insecure attachment representations. Secure mothers with unresolved loss displayed less frightening behavior than other mothers, and unresolved loss in secure mothers did not predict disorganized attachment of their infants. Frightening behavior predicted infant disorganized attachment irrespective of maternal security. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
