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.     

COLLEGE STUDENTS'ATTITUDES TOWARD EMPLOYEE DRUG TESTING PROGRAMS

Drug testing programs are becoming increasingly popular, but little is known about attitudes toward various aspects of common testing programs. This study examined college students'attitudes toward several aspects of drug testing programs. Results indicate that testing is seen, under some circumstances, as appropriate and necessary. However, attitudes toward most aspects of testing were characterized by extreme variability. Virtually all aspects of drug testing programs are strongly accepted by some individuals and strongly rejected by others. Furthermore, attitudes toward employee drug testing do not appear to vary as a function of employment experience, qualifications, or political inclinations, and are not strongly related to the individual's exposure to others'drug use. One of the few consistent correlates of approval of employee drug testing was the individual's drug use; self-report frequency of drug use was negatively correlated with the acceptability of employee drug testing.
