Examining the roles of reward sensitivity and difficulties in emotion regulation in relation to low-restraint binge eating.

Leading treatments for binge eating target dietary restraint, but up to 35% of the people with binge eating report low restraint. This study examined the roles of reward sensitivity and emotion dysregulation in relation to low-restraint binge eating. Women with binge eating (low-restraint:  = 22; high-restraint:  = 69) and controls ( = 49) completed self-report measures of generalized reward sensitivity and emotion dysregulation and a picture-viewing task assessing craving and pleasure for high-calorie food.

Capturing the experience of borderline personality disorder symptoms in the daily lives of women with eating disorders.

Borderline personality disorder (BPD) is highly comorbid with eating disorders (EDs), and comorbid ED-BPD is associated with a worse clinical presentation and treatment outcomes. Understanding how BPD symptoms manifest in the daily lives of those with EDs and predict momentary ED symptoms has important treatment implications. This study: (a) compared the nine BPD symptoms, assessed across 14 days, in individuals with comorbid ED-BPD, only an ED, and no ED; and (b) examined average and momentary relationships between BPD symptoms and specific ED symptoms (i.

Daily instability in body dissatisfaction in individuals with and without eating disorders.

Body dissatisfaction (BD) includes negative thoughts and feelings about one's body shape. Although typically assessed as a trait, BD has been found to fluctuate within a day. The present study examined whether daily instability in BD differs according to trait BD, eating disorder (ED) diagnosis, and engagement in maladaptive exercise.

Acting impulsively when "upset": Examining associations among negative urgency, undifferentiated negative affect, and impulsivity using momentary and experimental methods.

Introduction: Negative urgency is a personality pathway toward impulsive behavior that increases risk for transdiagnostic psychopathology. Limited research supports the core tenant of urgency theory, that is, that individuals with high trait negative urgency act more impulsive when experiencing increased negative emotion. We hypothesized that it may not be negative emotion intensity, but difficulty in differentiating among negative emotions, that prompts impulsive behavior among individuals with elevated negative urgency.

The roles of negative affect and emotion differentiation in the experience of 'feeling fat' among undergraduate students: An ecological momentary assessment study.

'Feeling fat' is the somatic experience of being overweight not fully explained by objective body mass. According to the body displacement hypothesis, 'feeling fat' occurs when diffuse negative emotions are projected onto the body in lieu of adaptive emotion regulation. Emotion differentiation, the ability to experience and label discrete emotions, is an important skill for adaptively addressing emotion that may reduce 'feeling fat.

Affective processes underlying restrictive eating in atypical anorexia nervosa: Comparisons to anorexia nervosa and bulimia nervosa using ecological momentary assessment.

Objective: Certain symptom and risk/maintenance factor similarities between individuals with atypical anorexia nervosa (AN) and 'typical' AN have been documented, but few studies have investigated how atypical AN compares to bulimia nervosa (BN). Further, the role of affective mechanisms in maintaining restrictive eating in atypical AN has not been examined. The current study investigated whether atypical AN resembles AN and/or BN on affect-related processes using questionnaires and ecological momentary assessment (EMA).

Gender differences in compulsive exercise facets and their associations with eating disorder symptoms.

Compulsive exercise (CE) is a core symptom of eating disorders (EDs) that is common in undergraduate men and women. Importantly, CE is a multidimensional construct, and certain facets of CE (i.e.

The role of self-compassion in the relationship between rejection and unhealthy eating: An ecological momentary assessment study.

Available studies suggest that experiencing interpersonal rejection heightens negative affect and, in turn, triggers unhealthy eating behaviors. Elucidating individual differences that attenuate the negative consequences of rejection could inform interventions targeting unhealthy eating. This study examined the buffering role of self-compassion in the relationship between rejection experiences and unhealthy eating behaviors, defined as snacking on junk food and overeating.

The roles of negative emotion intensity, negative emotion differentiation, and self-compassion in loss of control eating.

Objective: Negative affect intensity is robustly related to binge eating, but the relationship between negative emotion differentiation (i.e., the ability to differentiate negatively-valenced emotions) and binge eating is unclear.

Protection versus risk? The relative roles of compassionate and uncompassionate self-responding for eating disorder behaviors.

Research demonstrates the protective role of self-compassion for eating disorder symptoms. However, studies investigating self-compassion most often use the Self-Compassion Scale, which aggregates the distinct but related constructs of compassionate and uncompassionate self-responding. This study examined differential associations of compassionate and uncompassionate self-responding with positive and negative affect and with a range of eating disorder behaviors (i.
