Genetic Probes of Three Theories of Maternal Adjustment: I. Recent Evidence and a Model,

FAMILY PROCESS, Issue 3 2001
David Reiss M.D.
Studies focusing on genetic and social influences on maternal adjustment will illumine mother's marriage, parenting, and the development of psychopathology in her children. Recent behavioral genetic research suggests mechanisms by which genetic and social influences determine psychological development and adjustment. First, heritable, personal attributes may influence individuals' relationships with their family members. These genetically influenced family patterns may amplify the effects of adverse, heritable personal attributes on adjustment. Second, influences unique to siblings may be the most important environmental determinants of adjustment. We derive three hypotheses on maternal adjustment from integrating these findings from genetic studies with other contemporary research on maternal adjustment. First, mother's marriage mediates the influence of her heritable, personal attributes on her adjustment. Second, mother's recall of how she was parented is partially genetically influenced, and both her relationships with her spouse and her child mediate the impact of these genetically influenced representations on her current adjustment. Third, characteristics of mother's spouse are important influences on difference between her adjustment and that of her sister's These sibling-specific influences are unrelated to mother's heritable attributes. The current article develops this model, and the companion article describes the Twin Mom Study that was designed to test it as well, as its first findings. Data from this study can illumine the role of family process in the expression of genetic influence and lead to specific family interventions designed to offset adverse genetic influences. [source]

Genetic Probes of Three Theories of Maternal Adjustment: II.

FAMILY PROCESS, Issue 3 2001
Environmental Influences, Genetic
This is the first report of the Twin Mom Study, an investigation of three hypotheses concerning influences on maternal adjustment. These hypotheses concern the role of the marital and parent-child relationships in mediating genetic influences on maternal adjustment and on the importance of the mothers' marital partners as a specifiable source of influences on their adjustment not shared with their sisters. The study's sample of 150 monozygotic (MZ) twins and 176 dizygotic (DZ) twins was drawn randomly from the Swedish Twin Registry and is, with some small exceptions, likely to be representative of women in the Swedish population. The sample included the marital partners of these twins and their adolescent children. Self-report and coded videotapes were a source of information about family process. Results reported in this first report focus on comparability of American and Swedish samples on scales measuring psychiatric symptoms, and on an analysis of genetic and environmental influences on nine measures of mothers' adjustment. Results suggest comparability between the US and Sweden. Genetic influences were found for all measures of adjustment, particularly in the psychological manifestations of anxiety and for smoking. The pattern of findings also underscored the importance of influences unique to each sibling within the twin pair, thus focusing attention on the potential role of marital partners in maternal adjustment. Results also suggested that experiences shared by the twin sisters, experiences unrelated to their genetic similarity, may influence their fearfulness and alcohol consumption. Our model did not include these influences and thus must be amended. [source]

Korean mothers' psychosocial adjustment to their children's cancer

JOURNAL OF ADVANCED NURSING, Issue 5 2003
Hae-Ra Han PhD RN
Background., During the course of adjustment to their child's illness and medical treatment, parents of children with cancer may experience numerous challenges and difficulties. Although parental adjustment has been a research topic for many years, little research has been conducted among families in different cultures and countries. Aim., To identify factors that influence maternal psychosocial adjustment to childhood cancer using a new cultural group: Korean. Methods., A sample of 200 Korean mothers of children with cancer was included in the study. Guided by the double ABCX model of family adjustment and adaptation, a series of variables (i.e. maternal stress, coping, social support and selected illness-related and demographic questions) were examined for their relationships with maternal psychosocial adjustment to childhood cancer. Results., Using a hierarchical multiple regression, we found perceived level of stress, coping, social support, and time since diagnosis to be significant correlates of maternal psychosocial adjustment. Stress accounted for most (50%) of the total variance explained (56%) in maternal adjustment. Conclusion., The results suggest that the stress-coping framework may be appropriate in explaining maternal responses to childhood cancer across cultures. [source]

Population consequences of maternal effects: sex-bias in egg-laying order facilitates divergence in sexual dimorphism between bird populations

JOURNAL OF EVOLUTIONARY BIOLOGY, Issue 6 2002
A. V. Badyaev
Abstract When costs and benefits of raising sons and daughters differ between environments, parents may be selected to modify their investment into male and female offspring. In two recently colonized environments, breeding female house finches (Carpodacus mexicanus) modified the sex and growth of their offspring in relation to the order in which eggs were laid in a clutch. Here we show that, in both populations, these maternal effects strongly biased frequency distribution of tarsus size of fully grown males and females and ultimately produced population divergence in this trait. Although in each population, male and female offspring show a wide range of growth patterns, maternal modifications of sex-ratio in relation to egg-laying order resulted in under-representation of the morphologies that were selected against and over-representation of morphologies that were favoured by the local selection on juveniles. The result of these maternal adjustments was fast phenotypic change in sexual size dimorphism within and between populations. Maternal manipulations of offspring morphologies may be especially important at the initial stages of population establishment in the novel environments and may have facilitated recent colonization of much of North America by the house finch.

The psychosocial impact of parental cancer on children and adolescents: a systematic review

PSYCHO-ONCOLOGY, Issue 2 2007
Tessa Osborn
Abstract This review aimed to identify (i) whether early stage parental cancer is associated with an increased risk of psychosocial difficulties amongst children and adolescents; (ii) which factors are associated with variations in psychosocial functioning amongst these children and adolescents. Searches of four electronic databases and the reference lists of relevant articles revealed 10 studies which satisfied the inclusion criteria for the first review question and thirteen studies for the second. Limitations in methodological quality and modest numbers of studies examining the same variables, restricted the conclusions which could be drawn. Overall, the evidence suggests that children and adolescents do not generally experience elevated levels of serious psychosocial difficulties compared to reference groups, but they are at a slightly increased risk for internalising type problems. Adolescent daughters appear to be the most negatively affected group. The prevalent use of measures of child psychopathology may be masking more context-specific problems and lower levels of distress. Family variables, especially family communication/expressiveness, are consistently associated with child/adolescent psychosocial functioning and there is suggestive evidence for the role of maternal depression/adjustment and parenting variables. There is little evidence that medical/treatment variables are important predictors of child outcomes. These findings have implications for identifying families with children most in need of support and indicating variables to target in interventions. Copyright © 2007 John Wiley & Sons, Ltd. [source]
