Coping ability at mid-life in relation to genetic and environmental influences at adolescence: a follow-up of Swedish twins from adolescence to mid-life.
From 1964 to 1971, twins and singleton controls were followed from 10 to 16 years of age in Swedish schools. It was a nationally representative sample of 323 twin pairs, and 1193 classmate controls. In 1991 a follow-up was made of this sample with the purpose of investigating genetic influences on experienced family and school environments, as well as coping ability at the age of 35. The follow-up also evaluated the relation between coping ability at mid-life and family environment, as well as coping ability and school environment at adolescence for males and females. Genetic influences on perceived family and school environments, as well as on self-reported coping ability, have been investigated by means of comparisons of MZ and DZ twin pairs. A stepwise linear regression analysis was performed to assess environmental influences on coping ability at mid-life. The findings indicated that coping ability at mid-life is influenced by both genetic and environmental factors. Different environmental factors were operating for males and females, however. The results demonstrate that early environmental factors and genetic disposition have a long-term effect on coping ability.
