The serotonin transporter gene polymorphism (5HTTLPR) moderates the effect of adolescent environmental conditions on self-esteem in young adulthood: a structural equation modeling approach.
Repository Usage Stats
Here we examine the effects of both self-reported and independent observer-reported environmental risk indices, the serotonin transporter gene promoter (5HTTLPR) polymorphism, and their interaction on self-esteem. This trait was assessed during early and mid adolescence (mean age=14 and 16.5, respectively) and young adulthood (mean age=21.8) in a prospective cohort of 1214 unrelated participants in the Longitudinal Study of Adolescent Health (Add Health). Using structural equation modeling we identified a gene-environment (G×E) interaction using observer-report but not self-report measures of environmental stress exposure during adolescence: 5HTTLPR genotype and observer-reports of home and neighborhood quality (HNQ) during adolescence interacted to predict self-esteem levels in young adulthood (p<.004). Carriers of the s allele who lived in poor HNQ conditions during adolescence reported lower self-esteem in young adulthood than those with a good HNQ during adolescence. In contrast, among individuals with the l/l genotype, adolescent HNQ did not predict adulthood self-esteem. Genes may moderate the effect of adolescent environmental conditions on adulthood self-esteem.

Professor in Medicine
One of my major research foci is in the genetic basis of psychiatric and neurological disorders. I am currently involved in studies to dissect the genetic etiology of attention deficit hyperactivity disorder (ADHD), autism, chiari type I malformations, essential tremor, and neural tube defects. Additional research foci include genetic modifiers of sickle cell disease, and genetic contributions to birth outcomes, particularly among African American women.
Professor of Psychology and Neuroscience
Research in my lab concerns the means by which adolescents and emerging adults manage pursuit of their goals through self-regulation. We take a broad view of self-regulation, accounting for the separate and interactive influences of personality, environment (e.g., home, school, neighborhood), cognition and emotion, and social influences on the many facets of goal management. Although we occasionally study these influences in controlled laboratory experiments, our preference is to study the pu

My research efforts are in the area of developmental health psychology and organized around understanding the role of personality in health and disease in middle and later life. My primary research activity is as Principal Investigator of the UNC Alumni Heart Study (UNCAHS) a prospective epidemiologic study of 5000 middle aged men and women and 1200 of their spouses that evaluates the role of personality on coronary heart disease and coronary heart disease risk, cancer, and normal a
