Twin Offspring Study in Sweden - TOSS
The main focus of this study is to examine if patterns of genetic and environmental influences on associations between family relationships and women's adjustment also hold for men.
Studies that have examined genetic and environmental contributions to measures of family relationships and to associations between family relationships and mental health have found two different patterns of results for adults and children. For children, genetic factors explain most of the covariance between parent-child relationships and child adjustment, while in adults nonshared environmental factors account for most of the covariance between marital relationships and adult adjustment. These different patterns of findings suggest that different mechanisms are involved in linking pertinent family relationships to adjustment in children and adults.
This project extends the Twin Moms Project and includes a sample of twin fathers and their families (N=320 twin pairs and their families) and to collect an addition 250 pairs of twin mothers for a sample of 900 twin parents and their families (total N about 3,000 individuals). This expanded sample enables us to examine whether patterns of genetic and environmental influences on associations between family relationships and women's adjustment also hold for men. We also utilize the full twin families design in an effort to distinguish between different types of genotype-environment correlation for the associations between family relationships and child adjustment. As such, this information will enable us to understand better how and why relationships within the family affect the mental health of family members.
We have collected data on family relationships, including parent-child, marital and siblings, on adult and child mental health, and on the individual attributes of family members. Twin parents, their partner and the target child will participate through questionnaires and an interview, using a multi-agent, multi-method strategy.
