Narcissistic Vulnerability and Grandiosity as Mediators Between Insecure Attachment and Future Eating Disordered Behaviors: A Prospective Analysis of Over 2,000 Freshmen

OBJECTIVE

This study aimed to build on existing literature by examining the potential mediating role of two variants of narcissism (grandiosity and vulnerability) in explaining part of the underlying mechanism by which insecure (avoidant and anxiety) attachment affects behavioral elements of eating pathology (dieting and bulimic behaviors).

METHOD

Longitudinal data collected from 2,055 freshman college students (52.2% women; mean age 18.34 years) were analysed using a latent variable structural equation modelling approach, controlling for initial levels of the endogenous (i.e., dependent) latent variables and holding body mass index, anxiety, stress, depression, and self-esteem levels as time-varying covariates.

RESULTS

The effect of attachment anxiety on future bulimic behaviors was fully mediated through vulnerable narcissism (i.e., no significant direct link between attachment anxiety and bulimic behaviors), whereas grandiose narcissism fully mediated the association between attachment avoidance and future dieting behaviors. Dieting also predicted future bulimic behaviors and served as an additional (full) mediator between grandiose narcissism and bulimic behaviors. Differences in the strength of these associations across gender were not observed, and all indirect effects were statistically significant.

CONCLUSION

Overall, the findings (a) seem to support the theoretical postulations linking different insecure attachment experiences to different narcissistic tendencies, (b) imply that specific insecure attachment patterns may pass through different mediating pathways (narcissistic grandiosity and vulnerability) to specific behavioral elements of eating pathology (dieting and bulimic behaviors) regardless of gender, and (c) suggest that individuals with high grandiose narcissistic levels may not be protected from bulimic behaviors as previously indicated.

Virtual Reality-Enhanced Cognitive-Behavioral Therapy for Morbid Obesity: A Randomized Controlled Study with 1 Year Follow-Up

It is well known that obesity has a multifactorial etiology, including biological, environmental, and psychological causes. For this reason, obesity treatment requires a more integrated approach than the standard behavioral treatment based on dietary and physical activity only. To test the long-term efficacy of an enhanced cognitive-behavioral therapy (CBT) of obesity, including a virtual reality (VR) module aimed at both unlocking the negative memory of the body and to modify its behavioral and emotional correlates, 163 female morbidly obese inpatients (body mass index >40) were randomly assigned to three conditions: a standard behavioral inpatient program (SBP), SBP plus standard CBT, and SBP plus VR-enhanced CBT. Patients' weight, eating behavior, and body dissatisfaction were measured at the start and upon completion of the inpatient program. Weight was assessed also at 1 year follow-up. All measures improved significantly at discharge from the inpatient program, and no significant difference was found among the conditions. However, odds ratios showed that patients in the VR condition had a greater probability of maintaining or improving weight loss at 1 year follow-up than SBP patients had (48% vs. 11%, p = 0.004) and, to a lesser extent, than CBT patients had (48% vs. 29%, p = 0.08). Indeed, only the VR-enhanced CBT was effective in further improving weight loss at 1 year follow-up. On the contrary, participants who received only the inpatient program regained back, on average, most of the weight they had lost. Findings support the hypothesis that a VR module addressing the locked negative memory of the body may enhance the long-term efficacy of standard CBT.

The developmental effects of media-ideal internalization and self-objectification processes on adolescents' negative body-feelings, dietary restraint, and binge eating

Despite accumulated experimental evidence of the negative effects of exposure to media-idealized images, the degree to which body image, and eating related disturbances are caused by media portrayals of gendered beauty ideals remains controversial. On the basis of the most up-to-date meta-analysis of experimental studies indicating that media-idealized images have the most harmful and substantial impact on vulnerable individuals regardless of gender (i.e., "internalizers" and "self-objectifiers"), the current longitudinal study examined the direct and mediated links posited in objectification theory among media-ideal internalization, self-objectification, shame and anxiety surrounding the body and appearance, dietary restraint, and binge eating. Data collected from 685 adolescents aged between 14 and 15 at baseline (47 % males), who were interviewed and completed standardized measures annually over a 3-year period, were analyzed using a structural equation modeling approach. Results indicated that media-ideal internalization predicted later thinking and scrutinizing of one's body from an external observer's standpoint (or self-objectification), which then predicted later negative emotional experiences related to one's body and appearance. In turn, these negative emotional experiences predicted subsequent dietary restraint and binge eating, and each of these core features of eating disorders influenced each other. Differences in the strength of these associations across gender were not observed, and all indirect effects were significant. The study provides valuable information about how the cultural values embodied by gendered beauty ideals negatively influence adolescents' feelings, thoughts and behaviors regarding their own body, and on the complex processes involved in disordered eating. Practical implications are discussed.

Mechanisms of influence of body checking on binge eating

Despite the theorized role of body checking behaviours in the maintenance process of binge eating, the mechanisms by which they may impact binge eating remain unclear. Using objectification model of eating pathology as a theoretical framework, the authors examined the potential intervening roles of body shame, appearance anxiety, and dietary restraint in the pathway between body checking and binge eating. Data collected from a large sample of treatment-seeking people with Bulimic-type Eating Disorders (N = 801) were analysed trough structural equation modelling. Results showed that, regardless of specific DSM-5 diagnostic categories, body checking behaviours were indirectly associated with binge eating and dietary restraint through body shame and appearance anxiety, whereas dietary restraint was directly linked to binge eating. The findings have clinical utility as they contribute to gaining insight into how critical scrutiny of one's body may act in several indirect ways to affect binge eating. We discuss practical implications of the findings.
