Working out measurement overlap in the assessment of maladaptive exercise

Elizabeth W. Lampe, Katherine Schaumberg, David Kolar, Kathryn Coniglio, więcej

International Journal of Eating Disorders > 57 > 3 > 558 - 567

Objective Although exercise is generally considered healthy, many individuals engage in maladaptive exercise (e.g., compulsive in nature). Several definitions of maladaptive exercise exist, leading to multiple, varied assessment tools; assuming homogeneity across these assessments contributes to low consensus in etiological models. Method We used a Jaccard Index to quantify content overlap among...

Registered report: Initial development and validation of the eating disorders safety behavior scale

Erin E. Reilly, Brittany Bohrer, Daniel Sullivan, Jamal H. Essayli, więcej

International Journal of Eating Disorders > 54 > 4 > 660 - 667

Anxiety and eating disorders (EDs) often co‐occur, prompting calls to explore anxiety‐related maintenance processes in ED samples. Safety behaviors, which function to prevent a feared outcome from occurring or to reduce anxiety associated with a feared stimulus, are observed across anxiety disorders and, along with overt avoidance behaviors, are an important target in treatment. Data suggest that...

Are the Criterion B binge‐eating symptoms interchangeable in understanding binge‐eating severity? An item response theory analysis

Brianne N. Richson, Kelsie T. Forbush, Katherine Schaumberg, Ross D. Crosby, więcej

International Journal of Eating Disorders > 53 > 12 > 1983 - 1992

Objective The Criterion B binge‐eating symptoms represent five symptoms associated with binge eating. Any three out of five symptoms can be used to meet Criterion B. However, Criterion B symptoms may not be interchangeable in terms of how binge‐eating severity is associated with each symptom. Item response theory (IRT) can test how endorsing each symptom relates to the overall level (i.e., severity)...

Identifying a male clinical cutoff on the Eating Disorder Examination‐Questionnaire (EDE‐Q)

Lauren M. Schaefer, Kathryn E. Smith, Rachel Leonard, Chad Wetterneck, więcej

International Journal of Eating Disorders > 51 > 12 > 1357 - 1360

Objective Evidence suggests that eating disorders (EDs) may be under‐detected in males. Commonly used measures of EDs such as the Eating Disorder Examination‐Questionnaire (EDE‐Q) were initially developed within female samples, raising concern regarding the extent to which these instruments may be appropriate for detecting EDs in males. The current study used receiver operating characteristic curve...

Improving prediction of eating-related behavioral outcomes with zero-sensitive regression models

Katherine Schaumberg, Erin E. Reilly, Lisa M. Anderson, Sasha Gorrell, więcej

Appetite > 2018 > 129 > C > 252-261

Outcome variables gauging the frequency of specific disordered eating behaviors (e.g., binge eating, vomiting) are common in the study of eating and health behaviors. The nature of such data presents several analytical challenges, which may be best addressed through the application of underutilized statistical approaches. While zero-sensitive models are well-supported by methodologists, application...

Comparing internalization of appearance ideals and appearance-related pressures among women from the United States, Italy, England, and Australia

Lauren M. Schaefer, Natasha L. Burke, Lisa M. Anderson, J. Kevin Thompson, więcej

Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity > 2019 > 24 > 5 > 947-951

Researchers have observed variation in levels of body image disturbance and eating pathology among women from different Western countries. Examination of cross-cultural differences in the established risk factors (i.e., thin-ideal internalization, muscular-ideal internalization, and appearance pressures from family, peers, and media) for negative outcomes may help to elucidate the prominence of specific...

Dietary restraint and weight loss as risk factors for eating pathology

Katherine Schaumberg, Drew Anderson

Eating Behaviors > 2016 > 23 > C > 97-103

Measures of dietary restraint do not consistently predict caloric restriction, and these scales appear inadequate for differentiating between healthy and risky restraint in individuals. The current study examined the relationship between self-reported dietary restraint, recent weight loss, body mass index (BMI), and eating pathology in a college sample to determine if dietary restraint coupled with...

Energy intake highs and lows: how much does consistency matter in weight control?

Diane L. Rosenbaum, Leah M. Schumacher, Katherine Schaumberg, Amani D. Piers, więcej

Clinical Obesity > 6 > 3 > 193 - 201

Behavioural weight control programmes recommend adherence to daily energy intake goals, yet also allow for flexibility in intake across days. Evidence is lacking as to whether intake consistency is important for weight control. The current study explored the relation between day‐to‐day intake consistency and weight loss in the context of behavioural weight loss treatment and examined the relationship...

Gender-based differential item function for the difficulties in emotion regulation scale

Lisa M. Anderson, Erin E. Reilly, Sasha Gorrell, Katherine Schaumberg, więcej

Personality and Individual Differences > 2016 > 92 > C > 87-91

Emotion dysregulation is a mechanism central to the development and maintenance of various psychological disorders. Notably, men and women may differ in their experience of emotion regulation; for instance, women generally report more frequent use of problematic emotion regulation strategies. While considering the possibility that true gender differences in emotion regulation exist, it is also important...

The role of negative reinforcement eating expectancies in the relation between experiential avoidance and disinhibition

Katherine Schaumberg, Leah M. Schumacher, Diane L. Rosenbaum, Colleen A. Kase, więcej

Eating Behaviors > 2016 > 21 > C > 129-134

Eating-related disinhibition (i.e., a tendency to overeat in response to various stimuli) is associated with weight gain and poorer long-term weight loss success. Theoretically, experiential avoidance (i.e., the desire or attempts to avoid uncomfortable internal experiences), may predispose individuals to developing negative reinforcement eating expectancies (i.e., the belief that eating will help...
