Relation of binge eating age of onset to functional aspects of binge eating in binge eating disorder

OBJECTIVE: This study examined whether age of binge eating onset in binge eating disorder (BED) is related to affective binge eating antecedents and consequences. METHOD: Participants included women (N = 44) with BED who participated in a group cognitive-behavioral therapy (CBT) study. Measures included the Eating Hedonics Questionnaire, Beck Depression Inventory, Multidimensional Personality Questionnaire Negative Emotionality factor, Restraint Scale, Three-Factor Eating Questionnaire Restraint factor, and Eating Behaviors-IV. Participants were classified according to reported age of binge eating onset, with early onset defined as 13 years (LOB; n = 19). RESULTS: Compared with LOB, EOB was associated with reductions in postbinge subjective anxiety, but not depression. DISCUSSION: This study suggested that EOB in BED may be associated with binge eating as an affective means of coping, particularly with anxiety, and further supported age of binge eating onset as a clinically meaningful way to delineate BED subclassifications.     

Evaluating the effects of eating disorder memoirs on readers' eating attitudes and behaviors

OBJECTIVE: More than 50 individuals have published eating disorder (ED) memoirs. The current study was the first to test whether memoirs affect readers' eating attitudes and behaviors, and whether they normalize and/or glamorize EDs. METHOD: Fifty female undergraduates read an ED or control memoir. Before and afterward, participants completed the 26-item Eating Attitudes Test (EAT-26), the Eating Disorders Inventory (EDI) Drive for Thinness subscale, a measure of perceived ED symptom prevalence, and an Implicit Association Test (IAT) measuring associations between anorexia and glamour/danger. RESULTS: Participants in the ED condition did not demonstrate significant changes in the EAT-26, the EDI Drive for Thinness subscale, perceived symptom prevalence, or IAT associations compared with controls. Before reading, the EAT-26 and EDI Drive for Thinness subscale correlated positively with perceived symptom prevalence and strength of the IAT association between anorexia and glamour. CONCLUSION: ED memoirs appear to have little effect on undergraduates' eating attitudes and behaviors. Future research should investigate whether memoirs affect individuals with preexisting eating pathology, who may normalize and glamorize ED symptoms.     

Binge eating disorder and night eating syndrome: psychological and behavioral characteristics.

OBJECTIVE: The present study was designed to examine the psychological and behavioral characteristics associated with both night eating syndrome (NES) and binge eating disorder (BED) in 42 males and 41 females who were enrolled in a university-based weight loss center. METHOD: Individuals were classified into one of four groups: NES only (N = 23), BED only (N = 13), both NES and BED (N = 13), or no diagnoses of an eating disorder (N = 34). Analyses of covariance (covarying for age and gender) were conducted to compare patients with BED and NES. RESULTS: NES patients scored lower on disinhibition than BED patients (p <.01). Also, individuals who met criteria for both disorders scored higher than NES only patients on state anxiety (p <.01), disinhibition (p =.08), and trait anxiety (p =.08). DISCUSSION: These results suggest that NES represents a subcategory among the obese, which also overlaps with binge eaters. In addition, anxiety distinguished individuals who met criteria for both disorders from patients who were diagnosed with either NES or BED.     

A comparison of the binge eating scale, questionnaire for eating and weight patterns-revised, and eating disorder examination questionnaire with instructions with the eating disorder examination in the assessment of binge eating disorder and its symptoms

OBJECTIVE: The current study assesses concordance between self-administered measures and a diagnostic standard for assessment of binge frequency and diagnosis of binge eating disorder (BED) in a sample of binge eaters. METHOD: The Questionnaire for Eating and Weight Patterns-Revised (QEWP-R), Binge Eating Scale (BES), two items from the Eating Disorder Examination Questionnaire with Instructions (EDE-Q-I), and the Eating Disorder Examination (EDE) were administered. Participants were 157 adults volunteering for a clinical study, of whom 129 (79%) were diagnosed with BED using the EDE as the diagnostic standard. RESULTS: In the identification of BED, the QEWP-R yielded a sensitivity value of .74 and a specificity value of .35. The BES yielded a sensitivity value of .85 and a specificity value of .20. Frequency of binge eating days and episodes on the EDE-Q-I correlated highly with the EDE (.65 and .48, respectively; p < .001). DISCUSSION: The accuracy of diagnosis and symptomatology among self-administered questionnaires is variable. The BES and the QEWP-R performed satisfactorily as initial screens for the diagnosis of BED, but were less accurate in identifying non-BED individuals and the frequency of binge eating. The EDE-Q-I most accurately assessed the frequency of binge eating.     

Objective and subjective binge eating in underweight eating disorders: associated features and treatment outcome

Objective:

To define the utility of the DSM‐IV‐TR definition of binge eating, as it applies to anorexia nervosa (AN) and underweight eating disorder not otherwise specified (ED‐NOS).

Method:

We investigated the psychopathological features associated with bulimic episodes in 105 underweight individuals with eating disorders who reported regular objective bulimic episodes with or without subjective bulimic episodes (OBE group, n = 33), regular subjective bulimic episodes only (SBE group, n = 36) and neither objective nor subjective bulimic episodes (n = 36, no‐RBE group). The Eating Disorder Examination (EDE), anxiety, depression, and personality tests were administered before and upon completion of inpatient cognitive behavior therapy (CBT) treatment 6 months later.

Results:

Compared with the SBE group, OBE subjects had higher body mass index, and more frequent self‐induced vomiting, while both OBE and SBE groups had more severe eating disorder psychopathology and lower self‐directness than the no‐RBE group. Dropout rates and outcomes in response to inpatient CBT were similar in the three groups.

Discussion:

Despite a few significant differences at baseline, the similar outcome in response to CBT indicates that categorizing patients with underweight eating disorder on the basis of the type or frequency of bulimic episodes is of limited clinical utility. © 2011 by Wiley Periodicals, Inc.

Placebo response in binge eating disorder

OBJECTIVE: Placebo response in studies of binge eating disorder (BED) has raised concern about its diagnostic stability. The aims of this study were (1) to compare placebo responders (PRs) with nonresponders (NRs); (2) to investigate the course of BED following placebo response; and (3) to examine attributions regarding placebo response. METHOD: The baseline placebo run-in phase (BL) was part of a RCT investigating sibutramine hydrochloride for BED; it included 451 participants, ages 19-63, diagnosed with BED. Follow-up (FU) included 33 PRs. RESULTS:: In this study, 32.6% of participants responded to placebo (PRs = 147; NRs = 304). PRs exhibited significantly less symptom severity. At FU (n = 33), many PRs reported continued symptoms. CONCLUSION: PRs exhibited significantly less severe pathology than NRs. Placebo response in BED may transitory or incomplete. The results of this study suggest variable stability in the BED diagnosis.
