Associations Between Peer Pressure and Adolescents’ Binge Behaviors: The Role of Basic Needs and Coping

Framed from a framework based on the integration of self-determination theory (Ryan &; Deci, 2000 Ryan, R. M., &; Deci, E. L. (2000). Self-determination theory and the facilitation of intrinsic motivation, social development, and well-being. American Psychologist, 55(1), 68–78. doi:10.1037/0003-066X.55.1.68[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and Endler and Parker’s (1990) conception of coping strategies, the authors analyzed the relationships between peer pressure and binge behaviors (binge eating and binge drinking) in adolescence. Moreover, the authors explored the mediating role of satisfaction/frustration of basic psychological needs and coping strategies in these associations. Participants were 570 high school students (M?=?15.75 years, SD?=?1.14 years) living in Italy. The study design was cross-sectional and adolescents were administered self-report questionnaires. Path analysis showed significant and positive direct associations of peer pressure with both binge eating and binge drinking. Moreover, findings show that there is an indirect path in which peer pressure is positively associated with need frustration that is related to the use of emotion-oriented coping strategies that, on their turn, are associated with binge eating. Differently, binge drinking seems to be only directly related to peer pressure. The authors put light to the complex nature of the relationships between peer pressure and binge behaviors in adolescence, taking into account the separate contribution of need satisfaction and need frustration, as well as of coping strategies. Finally, practical implications of the study are discussed.     

Validation of the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Chinese adolescents

We sought to validate the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Chinese adolescents and investigate differences in eating behaviors among Chinese normal weight, overweight, and obese adolescents. Chinese middle and high school students completed the DEBQ, Eating Disorder Inventory-1, and the Self-Control Scale. Result showed that the DEBQ had good internal consistency, test–retest reliability and criterion validity. Furthermore, the obese and overweight adolescents scored significantly higher than normal weight adolescents on three subscales. The DEBQ is effective for assessing eating behaviors in Chinese adolescents.     

Cultural Adaptation of a Cognitive Behavior Therapy Guided Self‐Help Program for Mexican American Women With Binge Eating Disorders

Data on the compatibility of evidence‐based treatment in ethnic minority groups are limited. This study utilized focus group interviews to elicit Mexican American women's (N= 12) feedback on a cognitive behavior therapy guided self‐help program for binge eating disorders. Findings revealed 6 themes to be considered during the cultural adaptation process and highlighted the importance of balancing the fidelity and cultural relevance of evidence‐based treatment when disseminating it across diverse racial/ethnic groups.     

Resting EEG in alpha and beta bands predicts individual differences in attentional blink magnitude

Accuracy for a second target (T2) is reduced when it is presented within 500 ms of a first target (T1) in a rapid serial visual presentation (RSVP) - an attentional blink (AB). There are reliable individual differences in the magnitude of the AB. Recent evidence has shown that the attentional approach that an individual typically adopts during a task or in anticipation of a task, as indicated by various measures, predicts individual differences in the AB deficit. It has yet to be observed whether indices of attentional approach when not engaged in a goal-directed task are also relevant to individual differences in the AB. The current studies investigated individual differences in the AB by examining their relationship with attention at rest using quantitative measures of EEG. Greater levels of alpha at rest were associated with larger AB magnitudes, where greater levels of beta at rest were associated with smaller AB magnitudes. Furthermore, individuals with more beta than alpha demonstrated a smaller AB effect than individuals with more alpha than beta. Our results suggest that greater attentional engagement at rest, when not engaged in a goal-directed task, is associated with smaller AB magnitudes.     

Eating Behavior—Choice or Reconstruction of Past Experience? A Randomized Clinical Trial of Changing Eating Intentions of Healthy Adults Through Hypnotic Suggestions

Recent meta-analyses have shown that psychological interventions have a small to medium effect on weight loss. We propose here a different approach to changing eating intentions. According to the Free Will literature, people decide to act before they acknowledge it, and they decide based on the reconstruction of previous experiences. The action can thus be inhibited immediately (max 100 ms) after awareness. We wanted to test if intervention based on this model, using hypnotic suggestions, can effectively change the intentions of eating. This study aims to identify which format of hypnotic suggestion can be more effective in changing eating intentions regarding high-calorie foods. Therefore, 88 healthy adult participants randomized in four groups received one session of hypnotic induction and suggestions or placebo. We measured the eating intentions through a computer task in which participants could choose pictures of low and high caloric food before, during, and after hypnosis. For the within-subject effect, results showed that two types of hypnotic suggestions significantly impacted the intentions of eating on high-calorie foods with large-effect, namely Cognitive Rehearsal (d = 0.81, p < .001) and Memory Substitution (d = 0.82, p < .001). After controlling for pretest ratings, we found a significant between-effect: the Cognitive Rehearsal group differed significantly from the Control in terms of intentions of eating (d = 0.85, p < .05). We conclude that hypnosis with Cognitive Rehearsal suggestions can help to positively impact the intentions of eating.     

Support for a Transdiagnostic Motivational Model of Self-Damaging Behaviors: Comparing the Salience of Motives for Binge Drinking,Disordered Eating,and Nonsuicidal Self-Injury

Integrating across motivational models suggests that different self-damaging behaviors (SDBs) are enacted for similar reasons. However, it remains unclear whether some motives are more relevant to certain SDBs than others. To answer this question, the present study compared the salience of 8 potentially shared motives across 3 exemplar SDBs, selected to represent different points along the internalizing and externalizing spectra: binge drinking, disordered eating (binge eating, purging, fasting), and nonsuicidal self-injury (NSSI). Seven hundred and four first-year university students (73% female, M_age = 17.97) completed monthly surveys assessing their engagement in and motives for SDBs. Motives were conceptualized as either interpersonal (bonding with others, conforming with others, communicating strength, communicating distress, reducing demands) or intrapersonal (reducing negative emotions, enhancing positive emotions, punishing oneself). Multilevel models compared endorsement of each motive across SDBs. Results revealed that SDBs were motivated by similar goals, albeit to different degrees. Although some exceptions emerged, interpersonal motives were most salient to binge drinking, followed by disordered eating, and then NSSI. In contrast, intrapersonal motives were most salient to NSSI, followed by disordered eating, and then binge drinking. Motivational differences were also found within disordered eating. For example, punishing oneself was more relevant to purging and fasting than binge eating, whereas relieving negative emotions was more relevant to binge eating and purging than fasting. Similar to dimensional models that position SDBs on internalizing or externalizing spectra, the salience of motives for binge drinking and NSSI may fall on distinct spectra (i.e., interpersonal and intrapersonal, respectively), with motives for disordered eating exhibiting elements consistent with both spectra. This study supports a common motivational framework for investigating and potentially treating a variety of topographically distinct SDBs.     

An investigation of the psychometric properties of the Eating Disorder Symptom Impact Scale within an Australian sample

Caring for patients with an eating disorder (ED) is associated with a high level of burden and psychological distress. Currently, the Eating Disorder Symptom Impact Scale (EDSIS) is the only scale that measures the specific impact of caring for a patient with an ED. The initial development study within a British sample of carers indicated that the EDSIS has a four‐factor structure. The aim of the current study was to confirm the factor structure of the EDSIS within an Australian sample of carers. One hundred and fifty‐four carers completed the EDSIS. In contrast to the initial study, a six‐factor structure was derived explaining 69.66% of the variance: guilt, social isolation, confrontational behaviours, binge–purge difficulties, mealtime difficulties, and illness awareness. Reliability was acceptable (Cronbach's alpha range 0.69–0.88). Five of the six factors were moderately correlated with the General Health Questionnaire‐12 (r range = 0.24–0.51). A six‐factor solution may be a valid alternative for the EDSIS.     

Self-help for binge eating disorder in primary care: A randomized controlled trial with ethnically and racially diverse obese patients

Objective

The objective was to examine the effectiveness of a self-help treatment as a first line primary care intervention for binge eating disorder (BED) in obese patients. This study compared the effectiveness of a usual care plus self-help version of cognitive behavioral therapy (shCBT) to usual care (UC) only in ethnically/racially diverse obese patients with BED in primary care settings in an urban center.

Method

48 obese patients with BED were randomly assigned to either shCBT (N = 24) or UC (N = 24) for four months. Independent assessments were performed monthly throughout treatment and at post-treatment.

Results

Binge-eating remission rates did not differ significantly between shCBT (25%) and UC (8.3%) at post-treatment. Mixed models of binge eating frequency determined using the Eating Disorder Examination (EDE) revealed significant decreases for both conditions but that shCBT and UC did not differ. Mixed models of binge eating frequency from repeated monthly EDE-questionnaire assessments revealed a significant treatment-by-time interaction indicating that shCBT had significant reductions whereas UC did not during the four-month treatments. Mixed models revealed no differences between groups on associated eating disorder psychopathology or depression. No weight loss was observed in either condition.

Conclusions

Our findings suggest that pure self-help CBT did not show effectiveness relative to usual care for treating BED in obese patients in primary care. Thus, self-help CBT may not have utility as a front-line intervention for BED for obese patients in primary care and future studies should test guided-self-help methods for delivering CBT in primary care generalist settings.     

A randomized wait-list controlled pilot study of dialectical behaviour therapy guided self-help for binge eating disorder

This study examined the efficacy of guided self-help based on dialectical behaviour therapy (DBTgsh) for binge eating disorder (BED). Individuals (88.3% female; mean 42.8 years) were randomized to DBTgsh (n = 30) or wait-list (WL; n = 30). DBTgsh participants received an orientation, DBT manual, and six 20-min support calls over 13 weeks. All participants were assessed pre- and post-treatment using interview and self-report; also, DBTgsh participants were re-assessed six months post-treatment. At treatment end, DBTgsh participants reported significantly fewer past-month binge eating episodes than WL participants (6.0 versus 14.4) and significantly greater rates of abstinence from binge eating (40.0% versus 3.3%). At six-month follow-up, DBTgsh participants reported significantly improved quality of life and reduced ED psychopathology compared to baseline scores. In addition, most improvements in the DBTgsh group were maintained, although binge eating abstinence rates decreased to 30%. These preliminary positive findings indicate that DBTgsh may offer an effective, low-intensity treatment option for BED.     

Amplitude Scaling Compensates for Serial Delays in Correcting Eye and Arm Movements

Spatial and metrical parameters of the eye and arm movements made by human subjects (N = 7) in response to visual targets that were stepped unexpectedly either once (single step) or twice (double step) were studied. For the double-step, the displacement of a visual target was decreased or increased in amplitude at intervals before and during a movement. Provided the second target step occurred more than 100 ms before the onset of movement, the amplitude of the subjects' first response was altered in the direction of the new target location. But this amplitude scaling was not always sufficient to reach the new target location, and a second corrective response was required. The latency in producing this second response was greatly increased above reaction time latencies of movements to single-step targets, especially when the target change occurred 100 ms or more before movement onset. These findings suggest that even though serial processing limitations delay the production of a second corrective response, continuous parallel processing of visual information enables the amplitude of the first response to be altered with minimal delay. This enables some degree of real-time continuous control by the visuomotor control system.
