Dysfunctional Eating in an Australian Community Sample: The Role of Emotion Regulation,Impulsivity, and Reward and Punishment Sensitivity

This study aimed to examine the role of emotion regulation and reinforcement sensitivity in dysfunctional eating behaviours. Two hundred twenty‐eight adults from the Australian community completed self‐report inventories assessing the variables. Dysfunctional restrained eaters differed from those who did not engage in restrained eating in terms of their emotion regulation, impulsivity, and sensitivity to reward. Difficulties in emotion regulation, low impulsivity, and sensitivity to reward predicted engagement in restrained eating. Emotional eaters significantly differed from those who did not engage in dysfunctional levels of emotional eating in terms of their emotion regulation, impulsivity, and sensitivity towards reward, and difficulties in emotion regulation predicted emotional eating. Finally, dysfunctional external eaters differed from non‐dysfunctional external eaters in terms of their emotion regulation, impulsivity, sensitivity towards reward, as well as sensitivity towards punishment, and difficulties with emotion regulation and sensitivity towards reward predicted external eating. These findings highlight the importance of the inclusion of emotional functioning in models of development and maintenance of eating disorders, and support the potential implementation of treatment interventions that address emotion regulation and include strategies to cope with impulsivity and reinforcement sensitivities.     

Where is the chocolate? Rapid spatial orienting toward stimuli associated with primary rewards

Some stimuli can orient attentional resources and access awareness even if they appear outside the focus of voluntary attention. Stimuli with low-level perceptual salience and stimuli with an emotional content can modulate attention independently of voluntary processes. In Experiment 1, we used a spatial cuing task to investigate whether stimuli that are controlled for their perceptual salience can modulate the rapid orienting of attention based exclusively on their affective relevance. Affective relevance was manipulated through a Pavlovian conditioning paradigm in which an arbitrary and affectively neutral perceptual stimulus was associated with a primary reward (i.e., a chocolate odor). Results revealed that, after conditioning, attentional resources were rapidly oriented toward the stimulus that was previously associated with the reward. In Experiment 2, we used the very same conditioning procedure, but we devaluated the reward after conditioning for half of the participants through a sensory-specific satiation procedure. Strikingly, when the reward was devaluated, attention was no longer oriented toward reward-associated stimuli. Our findings therefore suggest that reward associations rapidly modulate visual processing independently of both voluntary processing and the perceptual salience of the stimulus. This supports the notion that stimuli associated with primary rewards modulate rapid attention orienting on the basis of the affective relevance of the stimulus.     

Exploring Criterion Confounding in the Measurement of Binge Eating Symptoms and Negative Affect

Common measures of eating disorder symptoms contain affect-related items. When associations between negative affect and eating disorder symptoms are examined, criterion confounding is possible. The current study explored whether criterion confounding biases estimates of relations between symptoms of binge eating and negative affect. Data were collected from first-year university student women via 14-day web-based daily diaries. The Minnesota Eating Behavior Survey (MEBS) measured daily symptoms of binge eating, and the Positive and Negative Affect Schedule (PANAS) measured daily negative affect. The inclusion of affect-related items in the MEBS biased mean level tests of negative affect, correlations of negative affect with symptoms of binge eating, and associations between the likelihood of reporting behavioral symptoms of binge eating and same-day negative affect. Converging results demonstrated the need to measure associated features and risk factors separately from problematic eating behavior symptoms.

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.     

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.     

The impact of advertisements featuring ultra‐thin or average‐size models on women with a history of eating disorders

Previous research demonstrates that exposure to ultra‐thin media models leads to increased body image concerns amongst women (Groesz, Levine, & Murnen, 2002 ). There is emerging evidence that attractive, average‐size models do not have this negative effect and can be effective in advertising (e.g. Halliwell & Dittmar, 2004 ). The present study investigates these factors amongst women with a history of eating disorders. Participants either viewed advertisements featuring ultra‐thin, average‐size or control images. Immediately after exposure, they reported their body‐focused anxiety and rated the effectiveness of the advertisements. Whereas exposure to ultra‐thin models did not lead to increased body‐focused anxiety, exposure to average‐size models produced a relief effect, whereby women reported lower levels of body‐focused anxiety. Advertisements featuring ultra‐thin and average‐size models were equally effective. The results suggest that average‐size, attractive models could be used effectively in advertising, which may help to relieve body image concerns amongst these women.

A closer look at the role of social influence in the development of attitudes to eating

The relationship between social influence and the development of attitudes to eating was explored in an experimental study. Schoolgirls (n=59, median age=15 years) listened to an interview in which the interviewee (identified as a radical feminist, a sportswoman or a women's magazine journalist) gave either a pro-diet or an anti-diet message. Following the interview, participants completed a questionnaire which examine their attitudes to eating and their judgements of the interviewee. The results supported predictions that influence would vary as an interactive function of the message and the normative ingroup–outgroup status of the message source. However, different patterns of influence were observed on two factors that emerged from an analysis of the eating disorder items, suggesting that there were important differences in the shaping of subjects' beliefs about appropriate eating behaviour, (a) for themselves personally and (b) for the community in general. The findings suggest that social influence has a significant but complex impact upon the development of potentially harmful attitudes to eating. It also appears that, for a variety of reasons, certain anti-diet messages may actually be a counter-productive means of improving female body satisfaction. © 1998 John Wiley & Sons, Ltd.     

A mixture hierarchical model for response times and response accuracy

In real testing, examinees may manifest different types of test‐taking behaviours. In this paper we focus on two types that appear to be among the more frequently occurring behaviours – solution behaviour and rapid guessing behaviour. Rapid guessing usually happens in high‐stakes tests when there is insufficient time, and in low‐stakes tests when there is lack of effort. These two qualitatively different test‐taking behaviours, if ignored, will lead to violation of the local independence assumption and, as a result, yield biased item/person parameter estimation. We propose a mixture hierarchical model to account for differences among item responses and response time patterns arising from these two behaviours. The model is also able to identify the specific behaviour an examinee engages in when answering an item. A Monte Carlo expectation maximization algorithm is proposed for model calibration. A simulation study shows that the new model yields more accurate item and person parameter estimates than a non‐mixture model when the data indeed come from two types of behaviour. The model also fits real, high‐stakes test data better than a non‐mixture model, and therefore the new model can better identify the underlying test‐taking behaviour an examinee engages in on a certain item.     

Individual Differences in Situation Awareness: Validation of the Situationism Scale

This article concerns the construct of lay situationism—an individual’s belief in the importance of a behavior’s context. Study 1 identified a 13-item Situationism Scale, which demonstrated good reliability and validity. In particular, higher situationism was associated with greater situation-control (strategies to manipulate the environment in order to avoid temptation). Subsequent laboratory studies indicated that people higher on the situationism subscales used greater situation-control by sitting farther from junk food (Study 2) and choosing to drink non-alcoholic beverages before a cognitive task (Study 3). Overall, findings provide preliminary support for the psychometric validity and predictive utility of the Situationism Scale and offer this individual difference construct as a means to expand self-regulation theory.     

The Sporting Body: Body Image and Eating Disorder Symptomatology Among Female Athletes from Leanness Focused and Nonleanness Focused Sports

Female athletes experience pressure to conform to social and sporting norms concerning body weight. This study compared general and sporting body dissatisfaction and disordered eating symptomatology among 320 elite, recreational, and noncompetitive female athletes aged 17 to 30 years competing in leanness focused sports and nonleanness focused sports. Participants completed an online questionnaire including demographic questions, the Eating Attitudes Test, and the Figure Rating Scale. Athletes from leanness focused sports reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of participation level. Elite athletes reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of sport type, and differences between recreational and noncompetitive athletes were not found. More than 60% of elite athletes from leanness focused and nonleanness focused sports reported pressure from coaches concerning body shape. The findings have important implications for identifying risk factors for eating disorders among female athletes, where athletes who compete at elite level and those who compete in leanness focused sports at any level may be at higher risk for developing eating disorders.
