OBJECTIVE Research shows a significant association between eating disorders (ED) and substance use disorders (SUD). The objective of this study is to examine the prevalence, chronology, and possibility of shared familial risk between SUD and ED symptomatology. METHOD Subjects included 1,206 monozygotic and 877 dizygotic adult female twins. ED(More)
The dopamine D3 receptor (DRD3) gene has been implicated in schizophrenia, autism, and substance use-disorders and is related to emotion reactivity, executive functioning, and stress-responding, processes impaired in posttraumatic stress disorder (PTSD). The aim of this candidate gene study was to evaluate DRD3 polymorphisms for association with PTSD. The(More)
Nectins are immunoglobulin-like cell adhesion molecules mainly localized in adherens junctions. The transcription factor p63 is a master regulator of gene expression in stratified epithelia and controls several molecular processes. As mutations in the Pvrl1 and Pvrl4 genes encoding for nectins cause genetic disorders with phenotypes similar to p63-related(More)
An accurate and precisely annotated genome assembly is a fundamental requirement for functional genomic analysis. Here, the complete DNA sequence and gene annotation of mouse Chromosome 11 was used to test the efficacy of large-scale sequencing for mutation identification. We re-sequenced the 14,000 annotated exons and boundaries from over 900 genes in 41(More)
OBJECTIVE These three studies examined the hypothesis that prenatal exposure to sex hormones influences twins' risk for eating disorders based on co-twin sex, such that individuals with a female co-twin would be more likely than individuals with a male co-twin to meet diagnostic criteria for an eating disorder. METHODS Male and female twins from the(More)
OBJECTIVE To evaluate the effects of a reality TV cosmetic surgery program on eating disordered attitudes, behaviors, mood, anxiety, and self-esteem. METHOD Participants (N=147 women) completed baseline surveys and were subsequently randomly assigned to one of two conditions: one in which they watched a reality TV cosmetic surgery program (The Swan) and(More)
The equal environments assumption, which holds that trait-relevant environments are equally correlated among monozygotic (MZ) and dizygotic (DZ) twin pairs, is essential to twin designs. Violations of this assumption could lead to biased parameter estimates in twin models. A variety of methods and measures have been used to test this assumption. No studies(More)
CONTEXT The familiality of borderline personality disorder (BPD) and its sectors of psychopathology are incompletely understood. OBJECTIVES To assess the familial aggregation of BPD and its 4 major sectors (affective, interpersonal, behavioral, and cognitive) and test whether the relationship of the familial and nonfamilial associations among these(More)
The fifth edition of the Diagnostic and Statistical Manual includes a dissociative subtype of posttraumatic stress disorder, but no existing measures specifically assess it. This article describes the initial evaluation of a 15-item self-report measure of the subtype called the Dissociative Subtype of Posttraumatic Stress Disorder Scale (DSPS) in an online(More)
OBJECTIVE Posttraumatic stress disorder (PTSD) has been associated with adverse health consequences, including overweight, obesity and cardiovascular disease. African Americans, particularly women, have among the highest rates of overweight and obesity in the U.S. compared to other racial groups. High rates of violence exposure in urban African Americans(More)
