Nowadays, obesity (OB) is one of the most important health problems in population-wide health. In addition to its physical consequences, it is a risk factor for the development of psychological problems, including body dissatisfaction (BD). This is why the treatment of BD is essential for its prevention. However, this has mostly been studied from a quantitative perspective, without focusing on the discomfort experienced by the person and the accompanying thoughts and emotions. In this study, 26 women with obesity (BMI > 30 kg/m2) participated, of whom 16 had high BD and 10 had low BD, as measured by the BSQ questionnaire. The women with high BD underwent six sessions of exposure to their own body in front of a mirror, recording the discomfort experienced with this vision during the session. In addition, all participants recorded positive and negative thoughts towards their body before and after these sessions. After the exposure treatment sessions, a reduction in symptomatology (BD, discomfort when visualizing one’s own body) was observed, as well as a change in the thoughts expressed by the participants, both in quantity (fewer negative thoughts) and in quality (a more positive self-perception and/or in more respectful terms used towards themselves). In conclusion, such treatments prove to be effective in reducing subjective discomfort and body-related thoughts in women with obesity.

Obesity is one of the most important health problems nowadays. In addition to the direct physical consequences, it is also a risk factor in the development of psychological (Eating disorders, body dissatisfaction, depression, anxiety, etc.) and social problems. Among there, body dissatisfaction is key for development and maintenance of such problems.OBJECTIVE:to deepen the effectiveness of the body exposure treatment, both in its pure form and guided modality in subjective, psychological and attentional levels in people with body dissatisfaction and obesity.METHODS:Evaluations were carried out in a total of 16 women with obesity and body dissatisfaction at the beginning and end of 6 treatment sessions of pure exposure in front of the mirror. The changes experienced at the subjective level (questionnaires and subjective discomfort during the sessions) and psychophysiological (eye-tracking and heart rate) were analyzed.RESULTS:Pure exposure treatment reduces negative thoughts and emotions towards the body itself, as well as the experienced discomfort towards the most conflictive parts. Selective attention to those parts of the body classified as uglier by the participants (especially the rear view of the body) show a decrease in physiological reactivity.CONCLUSIONS:Pure exposure treatment seems to be effective in reducing subjective and psychological symptoms associated with body dissatisfaction in people with obesity, this technique could be considered a good choice for the treatment of body dissatisfaction. This step is essential to guarantee the long-term therapeutic success of any other treatment (nutritional or/and physical activity) in the future.

This study examined whether poor health habits – those associated with a higher risk of developing eating disorders or obesity – modified adolescents’ emotions toward sweet food cues. We aimed to answer the following questions: Is adolescent obesity accompanied by excessive enjoyment of sweets? Or is any risk habit, regardless its stronger association with obesity or disordered eating, associated with less food enjoyment? 552 Spanish adolescents (279 females) viewed pictures of sweets interspersed with emotional images as controls. Participants recorded their feelings of pleasure, activation, control, and food craving while looking at each picture; then answered questions on their general health, food intake, and physical activity; finally, their body mass index was estimated. We performed MANCOVAs on feelings during sweets, including individual risk habits as factors, and sex, age, and hunger as covariates. We performed the same analysis on emotional and neutral images. Results revealed that among risk habits, obesity and unhealthy dieting practices were accompanied by less enjoyment of sweets (mostly less pleasure and less food craving). On the contrary, risk habits had no effect on adolescents’ feelings during emotional stimuli, unrelated to food. Thus, the presence of habits linked to obesity and disordered eating was associated with reduced reward value of sweet food cues, supporting the need to approach both disorders from an integrative perspective. Consistent with recent prevention strategies, the results suggest the potential role of food enjoyment as a protective factor.

This study aimed to examine the psychophysiological changes resulting from two mirror exposure treatments that are effective at reducing body dissatisfaction. Thirty-five university women with body dissatisfaction and subclinical eating disorders were randomly assigned to one of two groups: pure (n = 17) or guided exposure (n = 18). The participants received six sessions of treatment. Their thoughts, feelings and avoidance behaviours were assessed after each session. Their subjective discomfort, heart rate and skin conductance were assessed within the sessions. Both groups showed improvement in cognitive-affective and avoidance behaviour symptoms. Nevertheless, the pure exposure group showed faster habituation of subjective discomfort and a greater physiological response than the guided exposure group. These findings suggest that both procedures are effective interventions for improving body image disturbances, although psychophysiological changes observed within session suggest that each technique would act through different processes.

Recently, several sets of standardized food pictures have been created, supplying both food images and their subjective evaluations. However, to date only the OLAF (Open Library of Affective Foods), a set of food images and ratings we developed in adolescents, has the specific purpose of studying emotions toward food. Moreover, some researchers have argued that food evaluations are not valid across individuals and groups, unless feelings toward food cues are compared with feelings toward intense experiences unrelated to food, that serve as benchmarks. Therefore the OLAF presented here, comprising a set of original food images and a group of standardized highly emotional pictures, is intended to provide valid between-group judgments in adults. Emotional images (erotica, mutilations, and neutrals from the International Affective Picture System/IAPS) additionally ensure that the affective ratings are consistent with emotion research. The OLAF depicts high-calorie sweet and savory foods and low-calorie fruits and vegetables, portraying foods within natural scenes matching the IAPS features. An adult sample evaluated both food and affective pictures in terms of pleasure, arousal, dominance, and food craving, following standardized affective rating procedures. The affective ratings for the emotional pictures corroborated previous findings, thus confirming the reliability of evaluations for the food images. Among the OLAF images, high-calorie sweet and savory foods elicited the greatest pleasure, although they elicited, as expected, less arousal than erotica. The observed patterns were consistent with research on emotions and confirmed the reliability of OLAF evaluations. The OLAF and affective pictures constitute a sound methodology to investigate emotions toward food within a wider motivational framework. The OLAF is freely accessible at digibug.ugr.es.

Differences between bulimic anorectics and exclusive dieting anorectics were determined on both pretreatment and 1-year follow-up on the same assessment scales. At the time of follow-up there was no significant difference in the mean weights between the groups, however, there was a large within group weight variation. During pretreatment the exclusive dieters were significantly more depressed than the bulimics. This finding persisted at the time of the 1-year follow-up. The bulimics retained a greater sensitivity on interpersonal matters and remained more preoccupied with somatic complaints at the follow-up. Psychotic factors on two assessments discriminated bulimics from exclusive dieters at follow-up. Although there was considerable within group heterogeneity of signs and symptoms, the bulimics seem to be a more chaotic group with personality disorder features of lying, "psychotic tendencies," and stressed interpersonal relationships.

Background and Objectives: Body exposure improves body image problems in women with eating disorders. However it has almost always been combined with other interventions. Thus, the efficacy of body exposure alone (i.e., pure exposure) remains largely unclear. We aimed to compare the efficacy of two body exposure techniques through psychological and neuroendocrine indices recorded within and between successive sessions.Method: Twenty-nine women with high body dissatisfaction and diagnosis of bulimia nervosa were randomly assigned to one of two treatment groups: Pure Exposure (n = 14) or Guided Exposure (n = 15). Participants received 6 exposure sessions. After each session, changes in thoughts (positive/negative) and body satisfaction were assessed. Also, we assessed the body discomfort experienced by participants within and. between sessions. Finally, the changes in salivary cortisol levels within and between the initial and final treatment sessions were measured.Results: Both groups showed a reduction in negative thoughts and a progressive increase in positive thoughts throughout the treatment. However, the increase in body satisfaction and the reduction in subjective discomfort within the sessions were greater in the pure exposure group. The cortisol levels during the initial and final treatmept sessions decreased in both groups.Limitations: Methodological limitations are reported.Conclusions: These results suggest that pure and guided exposures are effective interventions for improving thoughts and neuroendocrine responses, although pure exposure increased more body satisfaction feelings in bulimic women. Subjective discomfort also showed different patterns of change within and along sessions for each treatment. Reasons for these results are discussed. (C) 2015 Elsevier Ltd. All rights reserved.

Purpose: This study aimed at comparing weight loss methods (WLM) performed near competition by elite judo athletes from different age and gender groups and relating WLM with the prevalence of eating disorders. Methods: 144 athletes (66 females and 78 males) from the Spanish judo teams participated in this observational descriptive study grouped into cadets, juniors, and seniors. Data were collected during previous training meetings to international tournaments. The used tools are a basic data questionnaire, State-Trait Anxiety Inventory (STAI-T), Food Craving Questionnaire-Trait (FCQ-T), Restraint Scale (RS), and Eating Attitude Test (EAT-40). Two-way ANOVAs and chi-square tests were used to compare groups. Results: Seniors presented higher use of WLM, especially one week before competition compared with juniors. Judoists were more involved in their diets and reduced more weight as they were older. Females were more concerned about their diets, presented higher anxiety, scored higher in the emotion scale, and more eating disorders symptoms, although weight loss was lower. Anxiety and eating disorders symptoms differences were more common in juniors and cadets, respectively, with higher scores in females. Conclusions and Implications: Seniors seem to develop more effective strategies to cope with weight loss. Cadet and junior females are more likely to suffer from the psychological-related states associated to weight loss. Implications: (1) Educational programs might help competitors and coaches to adopt and promote healthier weight loss processes, (2) special attention should be paid to female young judoists to detect eating disorders in its early stages, and (3) judo organizations should consider implementing new rules to sanction harmful weight loss practices.

BACKGROUND:Body dissatisfaction is the most relevant body image disturbance in bulimia nervosa (BN). Research has shown that viewing one's own body evokes negative thoughts and emotions in individuals with BN. However, the psychophysiological mechanisms involved in this negative reaction have not yet been clearly established. Our aim was to examine the emotional and attentional processes that are activated when patients with BN view their own bodies. METHOD:We examined the effects of viewing a video of one's own body on the physiological (eye-blink startle, cardiac defense, and skin conductance) and subjective (pleasure, arousal, and control ratings) responses elicited by a burst of 110 dB white noise of 500 ms duration. The participants were 30 women with BN and 30 healthy control women. The experimental task consisted of two consecutive and counterbalanced presentations of the auditory stimulus preceded, alternatively, by a video of the participant's own body versus no such video. RESULTS:The results showed that, when viewing their own bodies, women with BN experienced (a) greater inhibition of the startle reflex, (b) greater cardiac acceleration in the first component of the defense reaction, (c) greater skin conductance response, and (d) less subjective pleasure and control combined with greater arousal, compared with the control participants. CONCLUSION:Our findings suggest that, for women with BN, peripheral-physiological responses to self-images are dominated by attentional processes, which provoke an immobility reaction caused by a dysfunctional negative response to their own body.

In the last decades, food pictures have been repeatedly employed to investigate the emotional impact of food on healthy participants as well as individuals who suffer from eating disorders and obesity. However, despite their widespread use, food pictures are typically selected according to each researcher's personal criteria, which make it difficult to reliably select food images and to compare results across different studies and laboratories. Therefore, to study affective reactions to food, it becomes pivotal to identify the emotional impact of specific food images based on wider samples of individuals. In the present paper we introduce the Open Library of Affective Foods (OLAF), which is a set of original food pictures created to reliably select food pictures based on the emotions they prompt, as indicated by affective ratings of valence, arousal, and dominance and by an additional food craving scale. OLAF images were designed to allow simultaneous use with affective images from the International Affective Picture System (IAPS), which is a well-known instrument to investigate emotional reactions in the laboratory. The ultimate goal of the OLAF is to contribute to understanding how food is emotionally processed in healthy individuals and in patients who suffer from eating and weight-related disorders. The present normative data, which was based on a large sample of an adolescent population, indicate that when viewing affective non-food IAPS images, valence, arousal, and dominance ratings were in line with expected patterns based on previous emotion research. Moreover, when viewing food pictures, affective and food craving ratings were consistent with research on food cue processing. As a whole, the data supported the methodological and theoretical reliability of the OLAF ratings, therefore providing researchers with a standardized tool to reliably investigate the emotional and motivational significance of food. The OLAF database is publicly available at zenodo.org.

Emotional effects of upward body comparisons are suggested to occur automatically. A startle reflex paradigm was used to objectively examine the emotions elicited by viewing a picture of one's own body adopting a model pose or a neutral pose, in 30 women with high body dissatisfaction (HBD) and 33 women with low body dissatisfaction (LBD). In-task emotional responses in perceived valence, arousal and control were assessed. Additionally, post-task positive/negative and body-related beauty feelings were recorded. The results revealed that HBD women, compared with LBD women, showed (i) less pleasure, higher activation and less control whilst viewing their own bodies and (ii) less pleasure, more negative/ugliness feelings and an increased startle response when viewing themselves posing as models. The data showed that their own bodies provoked an immediate negative emotional state in HBD women. However, greater aversive psychophysiological mechanisms were automatically activated only when these women posed as models, suggesting that they made upward own-body comparisons.
