Two literature reviews address critical issues in the lives of many patients who rely on the safety net: language barriers to treatment and elevated rates of morbidity and mortality. Amy M. Bauer, M.D., M.S., and Margarita Alegría, Ph.D., examined effects on treatment quality of patients' limited English proficiency and the use of interpreters in mental health settings. The limited research in this area indicates that evaluation in a patient's nonprimary language can lead to incomplete or distorted mental status assessment. Both trained and untrained interpreters make errors, but use of professional interpreters may improve patient disclosure, referral to specialty care, and patient satisfaction (page 765). A healthier lifestyle is a key aspect of recovery among people with serious mental illness, and many interventions have been developed to improve diet and promote physical activity in this population. Leopoldo J. Cabassa, Ph.D., and colleagues examined three decades of outcomes research on such interventions. Twelve of the 23 U.S. studies reviewed found significant improvements in health. However, people from racial-ethnic minority groups were underrepresented (page 774).
