Friend support and psychological distress in a U.S. adult twin sample

Friend support is often assumed to exert direct environmental influences on psychological distress, yet the role of both genetic and environmental influences on this association has not been examined. This study investigates whether both genetic and environmental factors explain the link between friend support and psychological distress in adults. The sample was drawn from the Midlife Development in the United States study and included 947 pairs of monozygotic, same‐sex dizygotic (DZ), and opposite‐sex DZ twins. Results showed that genetic influences explain the association between friend support and psychological distress, suggesting that heritable contributions to friend support also shape psychological distress. Interventions focused on psychological distress should consider how individuals' heritable characteristics influence their friend support and psychological distress.     

Self‐esteem trajectories across 25 years and midlife intimate relations

Guided by a life‐span developmental systems approach, this study examined links between self‐esteem assessed over 25 years and adaptive interaction and relationship risk at midlife using data from 341 Canadian adults surveyed (or followed) from ages 18 to 43. Results showed higher self‐esteem at age 18 was associated with more adaptive interactions and lower perceived relationship risk at age 43. A more rapid increase in self‐esteem through the transition to adulthood into midlife (ages 18–43) was also associated with more frequent adaptive interactions and less relationship risk at age 43. These results held after accounting for potential confounding variables. This study is the first to demonstrate self‐esteem trajectories over a quarter century predict midlife intimate relationship functioning.     

THE FIRST ‘DESIGNER BABY’: The Role of Narratives,Cliche´s and Metaphors in the Year 2000 Media Debate

The public do not like, and we do not like the idea of designer babies (Ruth Deech, then Chair of the Human Fertilisation and Embryology Authority, quoted in The Independent, 18 October 2000). We are all on the slippery slope-the question we should be asking is: skis or crampons (Professor John Harris, The Centre for Social Ethics and Policy, University of Manchester, in an interview with Susan Johnson). LINGUISTIC AND CULTURAL GROUNDING OF THE DESIGNER BABY DEBATE In October 2000, news was released of the world’s first ‘designer baby’—Adam Nash who was born on 29 August 2000 in the United States. He was chosen as a donor for his sister Molly, who suffered with Fanconi Anaemia, which is a rare genetic disease. Without a bone marrow transplant, Molly would have died before the age of 10. A suitable donor had not been found, so her parents decided to undergo in vitro fertilization (IVF), and preimplantation genetic diagnosis (PGD) to select an embryo that would not carry the disease-causing gene and would become a brother and a donor for Molly. At the time of his birth, Adam’s cord blood was collected and later transplanted into his sister. Initial reports suggest that the treatment has been successful.
