Psychiatric Disorders and Childhood Parental Loss in Obesity: Relationship with the Mode of Weight Gain

We assessed the association between psychiatric disorders, childhood parental loss, and weight gain mode in 150 obese patients seeking bariatric surgery and with a history of sudden or gradual weight gain mode. Subjects with sudden weight gain mode (47%) showed significantly higher bipolar II disorder (p < .001), childhood parental death (p < .01), and separation (p < .01), but lower pure hypomania (p < .001) prevalence than subjects with gradual weight gain mode. We found preliminary evidence that lifetime bipolar spectrum disorders and childhood parental loss may influence weight gain mode in obese subjects. These findings may contribute to predict patients’ weight trajectories and implement preventive interventions.     

肥胖谈论:心理学视角下的沟通方式

肥胖谈论是一种关于身体外貌交流的社会现象,特别是指女性之间关于体型、体重和饮食习惯等自我贬损的谈话。通常认为女性通过肥胖谈论中的自我贬损,能够获得他人的安慰、支持以及印象管理等积极效果,但是研究表明肥胖谈论对身体意象、饮食失调、情绪等存在消极影响。未来的研究应该增加对肥胖谈论的纵向研究,进一步探究肥胖谈论的影响作用,扩展完善肥胖谈论的标准性操作。     

The feasibility,acceptability and possible benefit of a positive psychology intervention group in an adolescent inpatient eating disorder service

Positive affect focused therapies could increase subjective happiness and life satisfaction for patients with eating disorders (EDs), illnesses known to significantly impact quality of life. This longitudinal pilot study aimed to develop and implement a five session ‘Positivity Group’ using positive psychology interventions (PPIs) in an adolescent ED inpatient service. Eight female inpatients aged 11–18 years attended the group and subjective happiness and life satisfaction were assessed before, after and at 6-month follow-up. Patients provided feedback on acceptability and feasibility was assessed via patient engagement, facilitator and team feedback and the data support the feasibility and acceptability of the group. A possible benefit was derived from the group, with 75% of patients reporting meaningful improvement in subjective happiness and 87.5% in life satisfaction. Involving the wider team and supporting homework were identified as considerations for future replication alongside the assessment of implementation, acceptability, feasibility and effectiveness in other clinical contexts.     

Early Change Trajectories in Cognitive-Behavioral Therapy for Binge-Eating Disorder

Rapid response is considered the most well-established outcome predictor across treatments of binge-eating disorder (BED), including cognitive-behavioral therapy (CBT). This study sought to identify latent trajectories of early change in CBT and compare them to common rapid response classifications. In a multicenter randomized trial, 86 adults with BED (DSM-IV) or subsyndromal BED provided weekly self-reports of binge eating over the first 4 weeks of CBT, which were analyzed to predict binge eating, depression, and body mass index at posttreatment, 6-, and 18-month follow-up. Using latent growth mixture modeling, three patterns of early change—including moderate and low decreasing—as well as low stable binge eating were identified, which significantly predicted binge-eating remission at 6-month follow-up. Other classifications of rapid response based on Receiver Operating Characteristics curve analyses or on the literature (≥ 10% reduction in binge eating at week 1, ≥ 70% reduction in binge eating at week 4) only predicted posttreatment remission or overall depression, respectively. Latent change trajectories, but not other rapid response classifications, predicted binge-eating frequency over time. A fine-grained analysis of change over the first 4 weeks of CBT for BED revealed different trajectories of early change in binge eating that led to an improved prediction of binge-eating outcome, compared to that of common rapid response classifications. Thorough monitoring of early change trajectories during treatment may have clinical utility.     

神经质对青少年情绪化饮食的影响：一个有调节的中介效应模型

摘 要 为探讨神经质、青少年情绪化饮食、体验回避及自尊之间的关系,选取1000名青少年为被试,采用简式大五人格问卷、荷兰饮食行为问卷、接纳行动量表及自尊量表进行测试。结果表明：（1）神经质对青少年情绪化饮食有显著的正向影响,并间接地通过体验回避对青少年情绪化饮食产生作用;（2）自尊在体验回避对青少年情绪化饮食的影响中起显著的调节作用,具体而言,在低自尊水平下,体验回避能显著地正向预测青少年情绪化饮食,而在高自尊水平下,体验回避对青少年情绪化饮食的预测作用不显著。     

Emotional eating as a mediator between anxiety and cholesterol in population with overweight and hypertension

Although the relationship between cholesterol and mood states (especially anxiety) has been well studied, few researches have included the role of eating styles in this relationship. This study explored the associations among eating styles, negative emotional symptoms, and levels of cholesterol (and other medical variables) in a population with hypertension and overweight or obesity, analyzing the possible mediation mechanisms involved. A cross-sectional study was conducted in 68 adults with hypertension and overweight/obesity, and stepwise multiple regression analysis and mediation analyses were carried out to test the hypothesis that eating styles mediate the relationship between negative emotional symptoms and cholesterol. Several significant correlations among age, anthropometric, medical, and psychological variables (eating styles and negative emotional symptoms) were found. There was a significant indirect effect of anxiety on total cholesterol and LDL cholesterol through emotional eating. Results suggest that emotional eating has a relevant role in the rise in total and LDL cholesterol, acting as a mediator in the relationship between anxiety and cholesterol. This finding could have important implications, since it introduces a new variable in the relationship between emotions and cholesterol and, therefore, changes the way of understanding this relationship, and of treating high cholesterol in a hypertensive sample.     

Self‐efficacy or perceived behavioural control: Which influences consumers' physical activity and healthful eating behaviour maintenance?

This research investigated the role of a commercial program, Michelle Bridges 12 Week Body Transformation (MB12WBT), that uses a variety of tools including social support to influence weight management behaviours such as exercising and eating healthfully. The need for research into weight management remains current given obesity rates have continued to increase in recent decades. Weight management is a complex behaviour that for many consumers involves barriers that influence their commitment to continue exercising and eating healthily. The Theory of Planned Behaviour is frequently used to explain, and to a lesser extent predict, behaviours such as physical activity and healthy eating; however, there is much debate as to whether a perceived behavioural control variable or self‐efficacy is the best predictor of behaviour. Structural equation modelling was used to analyse data from a sample of 724 respondents who answered a baseline and three month follow‐up survey. The analysis revealed self‐efficacy and perceived behavioural control were two distinct constructs. Self‐efficacy was a better predictor of behaviour than perceived behavioural control variables as suggested in the original Theory of Planned Behaviour. Furthermore, self‐efficacy had a significant impact on exercising and eating healthfully behaviour. The findings and implications for both behaviour change theory and practice are discussed.
