Protecting Women from the Negative Effects of Body Dissatisfaction: The Role of Differentiation of Self

ABSTRACT

Body dissatisfaction is a prevalent and concerning issue among college age women. Due to its strong association with eating pathology, identification of moderating variables is a crucial line of inquiry. The present study investigated the ability for an intrapersonal differentiation-of-self variable (“I” position) to attenuate the impact of body dissatisfaction on anorexia and bulimia symptoms among college women participants. Study findings indicated that an “I” position moderated the body dissatisfaction-bulimia relationship and the body dissatisfaction-anorexia relationship. These findings signified the protective influence of a high “I” position for women with high levels of body dissatisfaction. Research and therapeutic implications are discussed.     

Understanding the prevalence and correlates of implicit theories of weight in the United States: Insights from a nationally representative sample

Objectives: The primary aim of this research is to understand how mindsets about weight controllability in the United States relate to population health. We examined the distribution of people’s implicit theories of weight, from an incremental (controllable) to an entity (not controllable) mindset, in a nationally representative sample, as well as their relation to: sociodemographic factors, beliefs about behaviour and genetics as causes of obesity and engagement in weight management-relevant behaviours.

Methods: We report data from the National Cancer Institute’s Health Information National Trends Survey 4.

Results: A majority of respondents endorsed an incremental mindset of body weight, but endorsement of this mindset was stronger among younger, white respondents, and those with a higher income and more educational attainment. A stronger incremental mindset was related to stronger behaviour and weaker genetic causal beliefs about obesity, as well as a tendency to report increased engagement in weight management-relevant behaviours.

Conclusions: Our research provides evidence that although incremental mindsets are more common overall and associated with engagement in health behaviours that can contribute to or detract from population health, incremental mindsets are less common among individuals from more marginalised groups.     

Body-ownership for actively operated non-corporeal objects

Rubber-hand and virtual-hand illusions show that people can perceive body ownership for objects under suitable conditions. Bottom-up approaches assume that perceived ownership emerges from multisensory matching (e.g., between seen object and felt hand movements), whereas top-down approaches claim that novel body parts are integrated only if they resemble some part of a permanent internal body representation. We demonstrate that healthy adults perceive body ownership for a virtual balloon changing in size, and a virtual square changing in size or color, in synchrony with movements of their real hand. This finding is inconsistent with top-down approaches and amounts to an existence proof that non-corporeal events can be perceived as body parts if their changes are systematically related to one’s actions. It also implies that previous studies with passive-stimulation techniques might have underestimated the plasticity of body representations and put too much emphasis on the resemblance between viewed object and real hand.     

Balancing awareness: Vestibular signals modulate visual consciousness in the absence of awareness

The processing of visual and vestibular information is crucial for perceiving self-motion. Visual cues, such as optic flow, have been shown to induce and alter vestibular percepts, yet the role of vestibular information in shaping visual awareness remains unclear. Here we investigated if vestibular signals influence the access to awareness of invisible visual signals. Using natural vestibular stimulation (passive yaw rotations) on a vestibular self-motion platform, and optic flow masked through continuous flash suppression (CFS) we tested if congruent visual–vestibular information would break interocular suppression more rapidly than incongruent information. We found that when the unseen optic flow was congruent with the vestibular signals perceptual suppression as quantified with the CFS paradigm was broken more rapidly than when it was incongruent. We argue that vestibular signals impact the formation of visual awareness through enhanced access to awareness for congruent multisensory stimulation.     

From Ideology to Feeling: Discourse,Emotion, and an Analytic Synthesis

Recent arguments in the social sciences exhort a turn to affect and, either explicitly or by implication, a move away from or beyond the earlier turn to language. This conveys a presumption that the site and logic of discursive investigation must inevitably be different to the site and logic of affective investigation. Instead, this article suggests that a nonreductive psychosocial understanding of both discourse and affect needs a way of dissolving the dualism which inhabits and motivates much current debate around discursive and affective “fields.” This article illustrates a route towards dismantling the apparent segregation of discourse and affect in the call to an affective turn. The data come from a project exploring women’s talk of success and failure. Analysis here focuses on affective-discursive practices in discussion of “failed attempts to control body weight” set within the context of contemporary western neoliberal ideology. Discourse and affect are both approached as semiotic, relational practice. As such, affect is made accessible to analysis via concepts already familiar in studies of discursive practice in social psychology, including the reproduction and negotiation of ideologies and the management of trouble. This analytic focus on practical deployments in interaction enables epistemological and ontological psychosocial arguments to be grounded in practical discursive-affective accomplishments.     

The Negative Physical Self Scale: Initial development and validation in samples of Chinese adolescents and young adults

This research presents four studies on the initial development and validation of the 48-item Negative Physical Self Scale (NPS), a multidimensional measure of body image concerns for use with Chinese samples. In Study 1 (N = 1095), exploratory factor analyses identified five dimensions underlying the NPS (General Appearance, Facial Appearance, Shortness, Fatness, Thinness). In Study 2 (N = 1057), confirmatory factor analyses replicated this factor structure. In Studies 3 and 4, the validity of all NPS dimensions except Thinness Concern was supported via their patterns of relation with both objective physical characteristics/behaviors and other self-report measures of body image and general self worth. Because Chinese adolescents and young adults expressed relatively more concerns about General Appearance, Shortness, and Facial Appearance than about Fatness, the NPS may have greater utility for assessing body image disturbances in China than existing measures that focus exclusively on general body satisfaction and body size/weight.     

The interference effect of men's handling of muscular action figures on a lexical decision task

It has been shown in previous work [Action figures and men. Sex Roles 53, 877–885] that male participants who handled extremely muscular action figures had lower body esteem than those who did not handle action figures or a Ken doll. However, the internal mechanisms that dictated this effect are unclear. Therefore, the current study extended this previous work by having male participants handle action figures of varying muscularity and completing a lexical decision task with target words that consisted of both positive and negative body words and feeling words in order to determine if males would be primed to think negatively about their bodies and self or if positive thoughts about their bodies and self would be interfered with. The results show that those participants who handled the extremely muscular action figures responded significantly more slowly to feeling positive words (e.g., content, confident) and marginally more slowly to body positive words (e.g., muscle, bicep) than those who did not handle any action figures. Overall, this suggests that the interference of positive words, not the priming of negative words, is the internal mechanism that produces the decreased body image satisfaction after exposure to muscular stimuli. Implications and future research are discussed.     

Raising the bar on the body beautiful: An analysis of the body image concerns of homosexual men

Research suggests that gay men are at particular risk for body image dissatisfaction. This study seeks to extend research on gay men's body image concerns. A survey assessed the nature and correlates of body image dissatisfaction among 64 gay men. The survey included assessments related to involvement in and perceived acceptance within the gay community, social comparison tendencies, body image satisfaction, self-esteem, and depression. The results indicate that most participants were concerned with muscularity rather than weight. Greater social comparison tendencies and higher body mass index (BMI) were associated with greater body dissatisfaction. Although involvement and perceived acceptance in the gay community did not independently predict general body image dissatisfaction, there is evidence to suggest that the association between body image and self-esteem may be moderated by integration into the gay community, defined as involvement and perceived acceptance. Implications for the further study of gay men's body image are discussed.     

Rates of abuse in body dysmorphic disorder and obsessive-compulsive disorder

Body dysmorphic disorder (BDD) continues to challenge professionals due to symptom severity, co-morbidity, suicidal ideation, and overvalued ideation. Despite the disorder's severity, little research exists. Clinical observation suggests a noteworthy history of abuse; therefore the present study investigated the reported rate of physical, sexual, and emotional abuse in BDD patients. OCD patients were chosen as a comparison group because BDD is considered to be an obsessive-compulsive spectrum disorder. A group survey design was used (N = 50 for each group). Results show significantly higher levels of emotional and sexual abuse in the BDD sample versus the OCD sample. No significant differences were found in physical abuse. Abuse may be a contributing factor in BDD, but not in OCD.     

Effects of exposure to muscular and hypermuscular media images on young men's muscularity dissatisfaction and body dissatisfaction

This study examined the effects of exposure to muscular and hypermuscular media images on young men's body images, and the moderating roles of baseline body dissatisfaction (BD) and muscularity dissatisfaction (MD). Men (M age = 21.9, SD = 2.8) were exposed to pictures of muscular (n = 34) or hypermuscular (n = 29) male physiques throughout a 30-min health seminar. In support of the study hypotheses, higher levels of baseline BD and MD were associated with greater post-seminar BD and MD. In addition, MD moderated the effects of the exposure conditions on BD; greater baseline MD was associated with greater post-seminar BD, but only among men who viewed the muscular images. These results speak to the importance of pre-existing muscularity concerns in determining men's reactions to muscular physique images, and suggest that exposure to the media ideal of muscularity, and not muscularity per se, elicits body dissatisfaction in men with pre-existing muscularity concerns.
