This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of positivity, negativity, control, and monitoring were used. The use of matched child-based and parent-based samples enabled passive and nonpassive genotype-environment (GE) correlations to be approximated, providing information about process. Passive GE correlations were suggested for mother's positivity and monitoring. For mother's negativity and control, primarily nonpassive GE correlations were suggested. In several cases, both types of GE correlation were indicated. Finally, observer ratings of negativity and monitoring were influenced only by environmental factors.

As most adults will marry at least once during their lifetime, studying marital quality and its predictors is of great importance. The current study addresses (a) the extent of agreement between husbands and wives on their marital quality, (b) genetic and environmental sources of individual differences on spouse reports of marital quality, and (c) the extent to which genetic and environmental influences account for overlap of spouse reports on marital quality. Adult Swedish twin women and their partners participated in this study. Genotype-environment (GE) correlations were found for marital quality, suggesting that wives' genetically influenced characteristics set a tone for the marriage. Wives' genetically influenced characteristics also accounted for overlap of spouse reports of marital quality. Finally, nonshared environmental influences were the primary contributor to both individual reports and the overlap of spouse reports, an interesting deviation from findings of behavior genetic studies of other types of relationships.

Sweden has now around 38,000 individuals who have been adopted from other countries. Most often they are transracially adopted and have a different appearance from their new parents--"visible" adoptions. This study was made to explore the mental health of a teenager/young adult group that arrived with their families in the southernmost county of Sweden between 1970 and 1977. They were placed through the largest Swedish adoption agency at that time. One hundred and forty-seven families and their 211 adopted children, who were 13 years of age or older at the time of the investigation, were interviewed in their homes. CBCL, SCL-90, a self-esteem questionnaire, and two family relations inventories were also completed. Compared to nonadopted Swedish young persons of the same ages, who had been investigated with the same inventories in earlier epidemiological studies, the adoptees had as good mental health. The adoptees also reported good self-esteem. The pre-adoption conditions were more important than the age of arrival in itself for the risk of later maladaptation. Family relations, various aspects of identity, and peer relations explained much of the variance of mental health and self-esteem. Those who were most engaged in questions about their identity and felt mostly non-Swedish had more behaviour problems. The association, however, between the factor "Identity" and the mental health variables approached zero for the older subjects (18-27 years of age). The majority (about 90%) of the adoptees felt mostly Swedish. Seventy per cent didn't feel any connection to their country of origin.
