What are you losing it for? Weight suppression motivations in undergraduates

Testing replicability of the relationship between weight suppression and binge eating in three non-clinical samples varying in lifetime weight history

OBJECTIVE

Increased weight suppression, the difference between an individual's highest and current weight at present height, predicts binge eating among eating disorder samples. Less is known about this relationship in non-clinical samples of individuals with a history of higher weight.

METHODS

Lifetime highest BMI was tested as a moderator of the relationship between weight suppression and binge eating in three independent samples (N = 1740).

RESULTS

At the bivariate level, weight suppression was not associated with binge eating in any sample (p's ≥ 0.20). Lifetime highest BMI moderated the relationship between weight suppression and binge eating in Sample 1 (p = .04), such that greater weight suppression was associated with lower binge eating among those with a history of higher weight (i.e., BMI = 40 kg/m2). In Samples 2 and 3, the lifetime highest BMI by weight suppression interaction term was not significant and dropped from the model (p's = 0.10-0.12). Accounting for age, gender, and lifetime highest BMI, greater weight suppression was associated with lower binge eating scores (p's < 0.04). A meta-analysis combining results revealed a small but significant interaction effect (r = 0.07, p = .02).

CONCLUSIONS

Findings highlight the importance of investigating the generalizability of eating disorder risk and maintenance theories across the weight spectrum. Weight loss may not increase risk for binge eating among those with a history of higher weight. Future work should replicate and extend this finding using longitudinal designs. More research is needed to elucidate which weight loss motivations and/or behaviors are most closely linked to binge eating.

Eating Disorder Examination-Questionnaire: Evaluating factor structures and establishing measurement invariance with Asian/Hawaiian/Pacific Islander, Black, and White American college men

OBJECTIVE

This study evaluated the factor structure and invariance of the Eating Disorder Examination-Questionnaire (EDE-Q) in a sample of Asian/Hawaiian/Pacific Islander (n = 163), Black (n = 155), and White (n = 367) American university men.

METHOD

Twelve different EDE-Q factor structures reported in the literature were evaluated using multi-group confirmatory factor analyses, and measurement invariance assessed.

RESULTS

A respecified four-factor structure proposed by Parker et al. (2016) showed superior fit and was invariant across groups. Significant differences emerged across all latent factors, with small to medium effects. Asian/Hawaiian/Pacific Islander men reported significantly higher scores on factors assessing Appearance Concern, Overvaluation of Shape/Weight, and Eating Concerns, and were more likely to endorse regular objective binge eating (OBE) and fasting episodes than their Black and White peers. Both White and Asian/Hawaiian/Pacific Islander men reported greater dietary restraint than Black men. Among this sample, frequencies of regular compensatory exercise ranged from 10% to 16%, fasting 6% to 14%, and OBEs 1% to 10%.

DISCUSSION

Results provide further support for the use of alternate EDE-Q factor structures, especially among non-White men. In this study, Asian/Hawaiian/Pacific Islander men reported the highest levels of ED psychopathology relative to White and Black men, indicating they might be particularly vulnerable to EDs.

PUBLIC SIGNIFICANCE

This study failed to find support for using the original Eating Disorder Examination-Questionnaire four-factor structure to detect disordered eating in Asian, Black, and White American college men. An alternate model proposed by Parker et al. in 2016 may be more appropriate. Asian men also reported the highest levels of eating psychopathology relative to their peers, suggesting they may be at high risk for developing eating disorders.

Effects of acceptance and reappraisal on body dissatisfaction: an experimental comparison of two adaptive emotion regulation strategies

BACKGROUND

In recent years, research has increasingly focused on body dissatisfaction, which is associated with numerous negative psychological and physical health consequences and, more importantly, with the development and maintenance of eating pathology.

OBJECTIVE

In the present study, we focused on the effect of two adaptive emotion regulation strategies (acceptance and reappraisal) on body dissatisfaction compared to a control group, and pre- and post-induction of body dissatisfaction.

METHODS

A total of 105 women [mean age (M) = 22.07; standard deviation (SD) = 6.11] were randomly assigned to one of the two emotion regulation conditions: acceptance (n = 35) and reappraisal (n = 35) or to a control group (n = 35). Participants were instructed accordingly with the condition that was assigned (acceptance or reappraisal). Participants were then induced body dissatisfaction by exposure to images representing the female thin-ideal and were asked to respond to their body-related feelings according to the instructions. Outcomes assessed were body dissatisfaction, and positive and negative affect.

RESULTS

Results indicated a significant increase of body satisfaction in the acceptance and reappraisal conditions from pre- to post-induction of body dissatisfaction, compared to control group which suffered a significant decrease in body satisfaction. Moreover, in the control group, positive affect significantly decreased and negative affect increased from pre- to post-induction, and did not change significantly, neither in the acceptance nor in the reappraisal condition.

CONCLUSIONS

Our findings highlight the positive effects of acceptance and reappraisal as emotion regulation strategies on body dissatisfaction and on positive and negative affect.
