Self-Objectification Among Physically Active Women

Objectification Theory (Fredrickson & Roberts, 1997) was used to examine (a) the mediation effects of body shame and flow on the relationship between self-objectification and disordered eating, (b) age differences in self-objectification, body shame, flow, and disordered eating, (c) the prediction of physical activity from self-objectification, flow, body shame, and disordered eating, and (d) the relationships between self-objectification, flow, and physical activity. Participants were 394 women ages 18–64. Results revealed that (a) body shame mediated the relationship between self-objectification and disordered eating, (b) younger women reported higher levels of self-objectification, body shame, dieting, and several flow characteristics, (c) older women scored higher on the loss of self-consciousness subscale of the flow measure, and (d) self-objectification was a significant predictor of physical activity.This article is based on the authors doctoral dissertation, which was completed at the University of North Carolina at Greensboro under the direction of Daniel Gould.     

Eating Disorders—The Regulation of Positive as well as Negative Emotion Experience

Disordered eating behaviors are often conceptualized as maladaptive emotion regulation strategies. The present study investigated links between emotional experience, schematic belief systems, and psychological themes associated with eating disorders. In contrast to the majority of studies, which focus on just one or two emotions and use nonclinical samples, this study compared the full range of emotional experience in women with eating disorders to a control group. Measures used include the Differential Emotional Scale-IV, Youngs Early Maladaptive Schema Questionnaire, and Eating Disorder Inventory-2. The study provides the first empirical evidence that women diagnosed with eating disorders report experiencing pleasant as well as unpleasant emotions more frequently than do controls. A surprising finding was that pleasant emotions (joy, interest, surprise) correlated with eating disorder themes (EDI-2 subscales) more consistently than unpleasant emotions in the eating disorder group, while the reverse was true of the control group. Also of note, eating-disordered women reported significantly less anger and similar levels of fear vs. controls. While eating-disordered women scored more highly than do controls on all maladaptive schema (suggesting high levels of distress in women with eating disorders), the pattern of correlations between schema and emotion experience was distinctly different for each group and counterintuitive for the eating disorder group. In particular, pleasant emotion was highly correlated with maladaptive schema in the eating-disordered group but not in the control group. These marked group differences in the pattern of relationships between emotion experience, eating disorder themes, and belief systems suggest that it is not valid to draw conclusions about eating disorders from research that employs only nonclinical samples. The authors discuss these findings, and suggest that women with eating disorders are proficient at using disordered eating behaviors to manipulate their experience of both positive and negative emotional states, and that this dynamic should be recognized as an important maintenance factor.     

Eating Disorders in Men: Current Considerations

Over the past two decades, there has been a change in the way men think about their bodies. The media portrays images of men with muscular bodies and a six pack abdomen. These images can create body dissatisfaction in males. With the change in the way that the media and society in the United States look at men, so has the drive for men to achieve this ideal body image. Eating disorders, body dysmorphia, and strict exercise and diet regimens seem to plague young men as do the images in advertisements. Although eating disorders in men are similar to what women experience, men seem to strive for more body mass whereas women try to obtain thinness. Gay men and heterosexual men seem to experience eating disorders in the same way although there are differences between how they perceive their bodies. This paper outlines how the media contributes to body dissatisfaction in men. In addition to understanding how the media affects men, it is important to review and possibly revise out understanding of eating disorders and body dysmorphia symptoms to gain a solid understanding of how these symptoms appear in men today.     

Situation Taxonomy and Behavioral Diagnosis Using Prospective Self-Monitoring Data: Application to Dietary Adherence in Patients with Type 1 Diabetes

The goals of this study were to create a taxonomy of problem situations for diet adherence in persons with insulin-dependent diabetes mellitus (Type 1 diabetes) and a behavioral diagnosis by grouping patients together who have similar adherence problems. In study one, 29 patients with Type 1 diabetes kept food diaries for 4 weeks. Adherence was assessed using eight behavioral measures: (1) compliance with a meal plan, (2) energy intake, (3) protein, (4) carbohydrates, (5) fat, (6) self-reported overeating, (7) self-reported undereating, and (8) ratings of impulsive eating. The occurrence of each behavior was quantified in a wide range of situational contexts including meal, social context, physical location, and mood. Cluster analysis of behaviors, situations, and behaviors-in-situations was used to create a hierarchical classification model consisting of five major categories of adherence problems: (1) compliance with meal plan, (2) undereating, (3) overeating, (4) impulsive eating, and (5) lifestyle differences. Within each category, situations were associated with everyday eating habits and special circumstances such as social events, and meals in restaurants. Grouping patients based on the similarity of their adherence problems resulted in five diagnostic groups: (1) emotional binge eaters, (2) restrained eaters, (3) unrestrained eaters, (4) undereaters, and (5) cyclical diet bingers. In study two, 28 subjects kept diaries during an intervention program designed to enhance dietary adherence. Study two results were similar to study one. Situation taxonomy and behavioral diagnosis are potentially useful ways to understand the intervention needs of those attempting maintaining dietary behavior changes.     

Establishing appropriate symptomatic control groups for the eating disorders

Two symptomatic control groups for the eating disorders were defined using high and low scores on the Dietary Restraint and Disinhibition scales of the Three Factor Eating Questionnaire. Clinical subjects diagnosed with anorexia and bulimia nervosa were compared with these symptomatic control groups using measures of body weight, bulimic symptoms, and anorexic symptoms. In comparison to the high-Restraint/low-Disinhibition group, anorexic subjects scored higher on measures of eating disorder symptoms but not on Restraint and Disinhibition. The high-Restraint/high-Disinhibition group differed from bulimia nervosa subjects on measures of eating disorder symptoms but did not differ on Restraint and Disinhibition. The results suggested that a control group defined by high Restraint and low Disinhibition formed an appropriate control group for anorexia nervosa. For bulimia nervosa, the most appropriate control group was defined by high Restraint and high Disinhibition.     

COMPARISON OF ESTABLISHED AND INNOVATIVE WEIGHT-REDUCTION TREATMENT PROCEDURES1

A central component of a commonly used weight-loss procedure developed by Stuart (1967), which emphasizes situational engineering (SE), was compared to eating behavior control (EBC), a treatment employing reinforcement of changes in eating habits. A third treatment encouraged development of individuals' own applications of a model of self-control and attempted to provide effective feedback regarding progress toward weight-loss goals. This self-initiated treatment (SI) was designed to be less directive than many behavioral treatment packages and to be more realistic about the expectations of subjects and the actual eating habits of overweight and normalweight people. Following baseline, treatment lasted six weeks and followup lasted 16 weeks. While all treatments produced weight losses, EBC surpassed SE during treatment. SI losses during treatment did not differ from SE or EBC, but SI was the only group that lost weight throughout followup, indicating the possible utility of more subtle, less directive interventions than those that have often been associated with behavioral approaches. The results of SE question the applicability to clinical procedures of the external cue hypersensitivity theory of obesity (Schachter and Rodin, 1974), to which SE is closely related.     

Eating Disorder Symptom and Fear Change Trajectories During Imaginal Exposure Therapy: A Slope Network Analysis

Eating disorders (EDs) are characterized by fears related to food, body image, and social evaluation. Exposure-based interventions hold promise for targeting a range of ED fears and reducing ED psychopathology. We investigated change mechanisms and optimal fear targets in imaginal exposure therapy for EDs using a novel approach to network analysis. Individuals with an ED (N = 143) completed up to four online imaginal exposure sessions. Participants reported ED symptoms and fears at pretreatment, posttreatment, and 6-month follow-up. We constructed networks of symptoms (Model 1), fears (Model 2), and combined symptoms and fears (Model 3). Change trajectory networks from the slopes of symptoms/fears across timepoints were estimated to identify how change in specific ED symptoms/fears related to change in other ED symptoms/fears. The most central changing symptoms and fears were feeling fat, fear of weight gain, guilt about one’s weight/shape, and feared concerns about consequences of eating. In Model 3, change in ED fears bridged to change in desire to lose weight, desiring a flat stomach, following food rules, concern about eating with others, and guilt. As slope networks present averages of symptom/fear change slopes over the course of imaginal exposure therapy, further studies are needed to examine causal relationships between symptom changes and heterogeneity of change trajectories. Fears of weight gain and consequences of eating may be optimal targets for ED exposure therapy, as changes in these fears were associated with maximal change in ED pathology. Slope networks may elucidate change mechanisms for EDs and other psychiatric illnesses.     

A Pilot Open Trial of a Digital Mindfulness-Based Intervention for Anorexia Nervosa

Anorexia nervosa (AN) is a chronic and debilitating psychiatric disorder. Unfortunately, current treatments are lacking, with only 30-50% of individuals with AN recovering after treatment. We developed a beta-version of a digital mindfulness-based intervention for AN called Mindful Courage-Beta, which includes: (a) one foundational multimedia module; (b) 10 daily meditation mini-modules; (c) emphasis on a core skill set called the BOAT (Breathe, Observe, Accept, Take a Moment); and (d) brief phone coaching for both technical and motivational support. In this open trial, we aimed to evaluate (1) acceptability and feasibility; (2) intervention skill use and its association with state mindfulness in daily life; and (3) pre-to-post changes in target mechanisms and outcomes. Eighteen individuals with past-year AN or past-year atypical AN completed Mindful Courage-Beta over 2 weeks. Participants completed measures of acceptability, trait mindfulness, emotion regulation, eating disorder symptoms, and body dissatisfaction. Participants also completed ecological momentary assessment of skill use and state mindfulness. Acceptability ratings were good (ease-of-use: 8.2/10, helpfulness: 7.6/10). Adherence was excellent (100% completion for foundational module and 96% for mini-modules). Use of the BOAT in daily life was high (1.8 times/day) and was significantly associated with higher state mindfulness at the within-person level. We also found significant, large improvements in the target mechanisms of trait mindfulness (d = .96) and emotion regulation (d = .76), as well as significant, small-medium to medium-large reductions in eating disorder symptoms (ds = .36–.67) and body dissatisfaction (d = .60). Changes in trait mindfulness and emotion regulation had medium-large size correlations with changes in global ED symptoms and body dissatisfaction (rs = .43 – .56). Mindful Courage-Beta appears to be promising and further research on a longer, refined version is warranted.     

Food wrenching and dodging: Eating time estimates influence dodge probability and amplitude

Eating rats dodge conspecifics, who are trying to steal their food, by making a somewhat stereotyped 180° turn and step movement to block the robber's approach. This experiment examined the effect of food features on the form and vigor of the dodging movement. Dodge probability and its amplitude were measured as a function of food size, elapsed eating time, food hardness, and the way in which food theft was attempted. Under all conditions dodge probability and its amplitude were directly related to the time necessary to complete eating. Thus, rats estimated the time required to complete eating and adjusted the size of their evasive movements to gain this time. The results show that although dodging has the appearance of a fixed-action pattern, it is influenced by cognitive processes that may be similar to those that direct other aspects of foraging behavior. © 1994 Wiley-Liss, Inc.     

Loneliness,eating, and body mass index in parent–adolescent dyads from the Family Life,Activity, Sun,Health, and Eating study

Loneliness is a salient risk factor for obesity, emotional eating, and poor diet. Because adolescents and parents are embedded within a family unit, their experiences of loneliness may be associated with both their own and one another's behaviors. To examine the extent to which parent and child loneliness predict body mass index (BMI) and eating in parents and adolescents, an actor–partner interdependence model of loneliness, eating, and BMI in adolescent–parent dyads was analyzed. There were actor effects among adolescents such that greater loneliness was positively associated with emotional eating and BMI‐z, and there was an actor effect among parents such that higher loneliness was positively related to emotional eating. There was a partner effect among adolescents such that greater parental loneliness was positively associated with adolescent emotional eating, and there was a partner effect among parents such that higher adolescent loneliness was positively associated with parental emotional eating. There were several actor–partner effects for loneliness and junk food in dyads with boys. Findings highlight the importance of dyadic models of loneliness in adolescent–parent dyads.
