Many current measures of eating disorder (ED) symptoms have 1 or more serious limitations, such as inconsistent factor structures or poor discriminant validity. The goal of this study was to overcome these limitations through the development of a comprehensive multidimensional measure of eating pathology. An initial pool of 160 items was developed to assess 20 dimensions of eating pathology. The initial item pool was administered to a student sample (N = 433) and community sample (N = 407) to determine the preliminary structure of the measure using exploratory and confirmatory factor analyses. The revised measure was administered to independent samples of patients recruited from specialty ED treatment centers (N = 158), outpatient psychiatric clinics (N = 303), and students (N = 227). Analyses revealed an 8-factor structure characterized by Body Dissatisfaction, Binge Eating, Cognitive Restraint, Excessive Exercise, Restricting, Purging, Muscle Building, and Negative Attitudes Toward Obesity. Scale scores showed excellent convergent and discriminant validity; other analyses demonstrated that the majority of scales were invariant across sex and weight categories. Eating Pathology Symptoms Inventory scale scores had excellent internal consistency (median coefficient alphas ranged from .84-.89) and reliability over a 2- to 4-week period (mean retest r = .73). The current study represents one of the most comprehensive scale development projects ever conducted in the field of EDs and will enhance future basic and treatment research focused on EDs.

Postpartum women often suffer clinically significant depressive symptoms, a problem addressed by nurse-delivered screening programs. In the past, success of these identification programs was measured in terms of screening rates; however, merely evaluating the screening rate does little to inform how to implement depression screening in clinical practice. This article describes the experiences of nurses in implementing depression screening on a maternity unit. We evaluate the practice qualitatively, by asking nurses to describe their screening strategies and their views about implementation, as well as quantitatively by assessing their screening rates and the number of women identified. Utilizing a framework of program evaluation, 20 maternity unit nurses completed qualitative assessments investigating their day-to-day experiences with this practice. To include the perspectives of nurses that declined to participate in qualitative assessments, 14 additional maternity unit nurses completed a brief survey assessing their views. We also assessed screening rates, defined as the number of women screened divided by the number eligible for screening. Maternity unit nurses viewed depression screening positively and were able to screen patients in relatively few steps, which they implemented using strategies they had developed themselves. Despite nurses' ongoing concern about finding time to screen, they achieved high screening rates and, with one exception, indicated they would opt to continue voluntarily. Depression screening on the maternity unit is feasible and embraced by attending nurses. The clinical strategies used to implement screening are extensively described and provide a basis for implementation in other settings that serve perinatal women.

The purpose of this study was to use an alternative, dimensionally based approach to understanding the reasons for comorbidity between eating disorders and obsessive compulsive disorder. Participants from a representative community sample (N=407; 47% female) completed self-report measures of eating pathology, obsessive-compulsive symptoms, perfectionism, and neuroticism. Hierarchical multiple regression indicated that neuroticism and perfectionism completely mediated associations between most obsessive-compulsive and eating disorder symptoms. However, body dissatisfaction shared unique associations with checking, cleaning, and obsessive rituals that could not be explained by these personality traits. Results suggest that shared personality traits play a key role in the comorbidity between eating disorders characterized by binge eating and dietary restraint and obsessive-compulsive disorder. Future studies are needed to examine whether similar underlying neurocognitive processes that give rise to compulsive checking, cleaning, and obsessive rituals may also contribute to the development and maintenance of body checking in individuals diagnosed with eating disorders.

This study aimed to determine if obese adults with poor versus good sleep quality demonstrate reduced self-regulatory capacity and different patterns of neural activation when making impulsive monetary choices. Six obese, good quality sleepers (M age = 44.7 years, M BMI = 83.1 kg/m2) were compared to 13 obese, poor quality sleepers (M age = 42.6, M BMI = 39.2 kg/m2) on sleep and eating behavior and brain activation in prefrontal and insular regions while engaging in a delay discounting task during functional magnetic resonance imaging (fMRI). Poor quality sleepers demonstrated significantly lower brain activation in the right inferior frontal gyrus, right middle frontal gyrus, and bilateral insula when making immediate and smaller (impulsive) monetary choices compared to the baseline condition. Behaviorally, poor compared to good quality sleepers reported higher scores in the night eating questionnaire. Obese adults with poor sleep quality demonstrate decreased brain activation in multiple regions that regulate cognitive control and interceptive awareness, possibly reducing self-regulatory capacity when making immediately gratifying decisions.
