Objective: Binge-eating disorder (BED) is characterized by recurrent episodes of binge eating and is associated with eating disorder and general psychopathology and overweight/obesity. Deficits in cognitive and emotional functioning for eating disorders or obesity have been reported. However, a systematic review on cognitive and emotional functioning for individuals with BED is lacking. Method: A systematic literature search was conducted across three databases (Medline, PubMed, and PsycINFO). Overall, n = 57 studies were included in the present review. Results: Regarding cognitive functioning, individuals with BED consistently demonstrated higher information processing biases compared to obese and normal-weight controls in the context of disorder-related stimuli (i.e., food and body cues), whereas cognitive functioning in the context of neutral stimuli appeared to be less affected. Thus, results suggest disorder-related rather than general difficulties in cognitive functioning in BED. With respect to emotional functioning, individuals with BED reported difficulties similar to individuals with other eating disorders, with a tendency to show less severe difficulties in some domains. In addition, individuals with BED reported greater emotional deficits when compared to obese and normal-weight controls. Findings suggest general difficulties in emotional functioning in BED. Thus far, however, investigations of emotional functioning in disorder-relevant situations are lacking. Discussion: Overall, the cross-sectional findings indicate BED to be associated with difficulties in cognitive and emotional functioning. Future research should determine the nature of these difficulties, in regards to general and disorder-related stimuli, and consider interactions of both domains to foster the development and improvement of appropriate interventions in BED.

Objectives: Binge-eating disorder (BED) is characterized by recurrent binge eating episodes, associated eating disorder and general psychopathology, and commonly occurs in obese individuals. Explicit self-esteem and explicit weight bias have been linked to BED, while little is known about implicit cognitive processes such as implicit self-esteem and implicit weight bias. Methods: Obese participants with BED and an individually matched obese only group (OB) and normal weight control group (CG; each N = 26) were recruited from the community to examine group differences and associations in explicit and implicit self-esteem and weight bias, as well as the impact of implicit cognitive processes on global eating disorder psychopathology. Implicit cognitive processes were assessed using the Implicit Association Test. Results: Significantly lower explicit self-esteem, as well as higher exposure to explicit weight bias, compared to CG and OB was found in the BED group. All groups showed positive implicit self-esteem, however, it was significantly lower in BED when compared to CG. BED and CG demonstrated equally high implicit weight bias whereas OB did not. Explicit and implicit measures were not significantly correlated. Global eating disorder psychopathology was predicted by explicit and implicit self-esteem. Conclusions: The results of the present study add to the importance of implicit self-esteem and implicit weight bias beyond explicit measures in BED, while both were previously shown to be associated with onset and maintenance of BED. In conclusion, implicit cognitive processes should be focused on in interventions for BED to investigate their impact on psychological treatments.

While cognitive-behavioral therapy (CBT) is the most well-established treatment for binge-eating disorder (BED), little is known about process factors influencing its outcome. The present study sought to explore the assessment of therapist adherence, its course over treatment, and its associations with patient and therapist characteristics, and the therapeutic alliance. In a prospective multicenter randomized-controlled trial comparing CBT to internet-based guided self-help (INTERBED-study), therapist adherence using the newly developed Adherence Control Form (ACF) was determined by trained raters in randomly selected 418 audio-taped CBT sessions of 89 patients (25% of all sessions). Observer-rated therapeutic alliance, interview-based and self-reported patient and therapist characteristics were assessed. Three-level multilevel modeling was applied. The ACF showed adequate psychometric properties. Therapist adherence was excellent. While significant between-therapist variability in therapist adherence was found, within-therapist variability was non-significant. Patient and therapist characteristics did not predict the therapist adherence. The therapist adherence positively predicted the therapeutic alliance. The ACF demonstrated its utility to assess therapist adherence in CBT for BED. The excellent levels of therapist adherence point to the internal validity of the CBT within the INTERBED-study serving as a prerequisite for empirical comparisons between treatments. Variability between therapists should be addressed in therapist trainings and dissemination trials.

Hazardous alcohol consumption is an issue that affects a lot of university students today. Consuming alcohol tend to have a negative impact on both mental and physical aspects, which can lead to severe alcohol addictions in the future. This study investigates which background factors that causes the phenomenon of binge drinking by collecting and analysing data from Linköping University. The results were analysed with data mining techniques such as: decision trees, random forest, and logistic regression. The results showed that logistic regression were the most reliable method in predicting binge drinking with an accuracy of (86.50 %), precision (92.64 %) and recall (90.96 %). The findings also showed that participation in student events together with higher weekly alcohol consumption predicted binge drinking. Additionally, other risk factors were the amounts of time the students spent with their friends and the students activity in partaking in their programs section (program association). The results from this study suggest that the student culture not only influence alcohol consumption but it induces the habits of binge drinking.

The diploma thesis is focusing on the topic of eating disorders in young men. The literature review summarizes the current information concerning eating disorders in this population. Eating and feeding disorders included in DSM - 5 are described. The thesis also focuses on orthorexia nervosa and muscle dysmorphia. A separate chapter deals with body image in men and its connection to eating disorders. The final chapter of the literary review section is focused on the possibilities of diagnostics and therapy. The empirical part of the work consists of a quantitative research conducted on a sample of 164 men aged 18-30 years. A questionnaire survey was carried out. Using Spearman's correlation coefficient, a significant correlation was found between the symptomatology of eating disorders and muscle dysmorphia. There was also a significant correlation between Body Mass Index and the symptoms of eating disorders and also between BMI and muscular dysmorphia. Data analysis revealed a positive correlation between the higher symptomatology of eating disorders and dissatisfaction with the amout of body fat. No significant relationship was found between the symptomatology of eating disorders and dissatisfaction with muscle mass. There was a significant correlation between Body Mass Index and dissatisfaction...

Indiana University-Purdue University Indianapolis (IUPUI) / Extrasynaptic GABAA receptors, often identified as those containing both α4 and δ subunits, appear to be a target for the actions of alcohol (ethanol) at relatively low concentrations, perhaps suppressing the activity of GABAergic interneurons which regulate activity in the mesolimbocortical circuit. Pharmacological studies in rodents using the δ-subunit selective agonist Gaboxadol (THIP) have found both promotional and inhibitory effects on alcohol consumption. The goal of this project was to determine the role of extrasynaptic GABAA receptors located in the infralimbic cortex (ILC) in the binge-like alcohol intake of male C57BL/6J (B6) mice. The ILC is of interest due to its demonstrated involvement in stress reactivity and alcohol exposure has been shown to interfere with extinction learning; impairments of which may be related to inflexible behavior (i.e. problematic alcohol consumption). Adult male B6 mice were bilaterally implanted with stainless steel guide cannulae aimed at the ILC and were offered limited access to 20% ethanol or 5% sucrose for 6 days. On day 7, mice were bilaterally injected with 50 or 100 ng THIP (25 or 50 ng per side respectively) or saline vehicle into the ILC. It was found that the highest dose of THIP (100 ng/mouse) increased alcohol intake relative to vehicle controls, although control animals consumed relatively little ethanol following infusion. Furthermore, THIP had no effect on sucrose consumption (p > 0.05), suggesting that the effect of THIP was selective for ethanol consumption. Together, these findings suggest that the mice that consumed ethanol may have been particularly reactive to the microinfusion process relative to animals that consumed sucrose, perhaps because ethanol consumption was not as reinforcing as sucrose consumption. In addition, the observation that THIP effectively prevented the decrease in ethanol intake on day 7 induced by the microinjection process may be related to a role for the ILC in adaptive learning processes, which in turn, promote behavioral flexibility.

Objective: Numerous studies trying to find the causes and implications of binge drinking on college campuses have focused their attention on the heavy drinkers. The purpose of this study was to understand why and how college students choose to abstain from drinking. The study also examined the experiences of the abstaining college students on a campus where 83% of the student body drinks. Methods: Twelve undergraduate students from the University of Richmond participated in this qualitative study. Individual interviews using open-ended questions were conducted to ascertain the reasons for their abstinence and their experiences as college students. After the interviews, the 12 students were assigned to focus groups to discuss and compare their experiences and to test emergent themes.Results: The three most often mentioned reasons for the decision to abstain were (a) they wanted to maintain control over their body and environment, (b) it is illegal to drink under age 21 and (c) they did not want to disappoint their parents. The students described needing strong personal convictions about the decision to abstain in order to stand up to social pressures to fit in. Most of the students (11) made the decision during their high school years. A supportive network of peers and high parental expectations helped solidify the decision to abstain throughout high school. The transition period into college and the development of a social network is the most difficult time to be an abstainer, since most social activities revolve around drinking. The meaning they gave to their experience on campus was that it is more difficult to develop a social network as an abstainer, but the relationships are deeper and more genuine than those developed over nights of drinking. Conclusions: The choice to abstain from drinking is often made during high school and maintained through social support. The transition into college and the lack of a social network is a tenuous period during which the decision to abstain is challenged. University administrators need to look into alternative ways in which new students can develop their social network where drinking is not the primary focus.

Doctor of Philosophy / Department of Family Studies and Human Services / Jared A. Durtschi and Sandra M. Stith / Early binge drinking (i.e., five or more drinks on a single occasion) is associated with a greater risk of later substance abuse or dependence, and other non-alcohol related problems in adulthood, (e.g., adult civil or criminal convictions). Identifying alcohol use trajectories has mainly been limited to within single developmental periods (i.e., adolescence or emerging adulthood) or between developmental periods up until around the legal drinking age. Using N = 1,864 adolescents from the National Longitudinal Study of Adolescent Health (Add Health) dataset, this paper sought to identify trajectories of binge drinking beginning in adolescence and into adulthood using growth mixture modeling. Family factors (e.g., parent-child communication, shared activities, connectedness, and parental control) were used to predict the various trajectories. Two class trajectories were identified, a low initial-escalating group (87%), and a high initial-deescalating group (13%). Being male and having more close friends using alcohol were predictive of a greater likelihood of being in the high initial-deescalating group. Results can inform therapeutic interventions in an effort to affect an adolescent’s trajectory of use and reduce the risk of long-term heavy alcohol use.

Introdução: O aumento da expectativa de vida e da prevalência de doenças crônicas, como o diabetes mellitus (DM), mudou o foco das agências governamentais de saúde. O DM causa complicações crônicas graves comprometendo a qualidade de vida (QV) e a sobrevida; em concomitância com transtornos psiquiátricos como depressão e compulsão alimentar periódica (CAP) piora adesão ao tratamento e deteriora o prognóstico. É possível que abordagem psicoeducativa reverta em melhor controle metabólico e QV por meio de programa de mudanças de hábitos de vida. Objetivo: Avaliar se intervenção no estilo de vida com abordagem intensiva interdisciplinar a indivíduos de risco para DM resulta em melhor QV que a intervenção tradicional (IT). Métodos: 177 indivíduos pré-diabéticos ou portadores de síndrome metabólica, atendidos pelo SUS, foram alocados aleatoriamente para uma IT ou intensiva (II) em hábitos de vida por 9 meses. O grupo de IT foi submetido a consultas médicas trimestrais e o grupo II, além destas, participou de 13 sessões de grupos psicoeducativos para mudanças em hábitos alimentares e atividade física. No momento basal e após 9 meses submeteram-se a exames clínico-laboratoriais e a questionários: versão longa do IPAQ, recordatórios alimentares de 24h, de QV (SF-36), para depressão (IBD e PRIME-MD) e escala de CAP. Fatores preditivos de adesão definida como participação em pelo menos 70 por cento das sessões psicoeducativas foram analisados em modelo de regressão logística. Resultados: Em ambas as intervenções houve melhora significante do IMC, circunferência abdominal e HDL. Após 9 meses, apenas os indivíduos da II reduziram pressão arterial e glicemia. O grupo II obteve melhora significante da QV na maioria dos domínios do SF-36 e nas medidas-resumo do componente físico e mental. Comparando os incrementos na QV induzidos pelas intervenções, foram maiores nos domínios capacidade física (II: 11,1±14,0 vs. IT: 5,3±13,0; p=0,02) e aspecto emocional (II: 20,4±40,2 vs. IT: 16,2±43,8; p=0,05) na II em relação à IT. As frequências de depressão reduziram em ambas as intervenções aos 9 meses, porém as de CAP diminuíram apenas na II (28,0 para 4,0 por cento, p<0,001; IT: 13,7 por cento para 8,6 por cento; p=0,38). As mudanças nos domínios do SF-36 se correlacionaram inversa e significantemente com os deltas do IMC, circunferência abdominal, pressão arterial sistólica e glicemia. Também se detectou correlação inversa dos escores de QV com os de depressão (r= -0,275; p=0,001) e de CAP (r= -0,175; p=0,043). Regressão logística mostrou que o sexo masculino associou-se independentemente à adesão à II (p=0,02), mas não a presença de CAP ou depressão. Conclusão: Intervenção no estilo de vida com abordagem interdisciplinar em indivíduos de risco para DM beneficia mais a QV que IT, em paralelo à melhora metabólica. O controle da CAP e depressão parecem contribuir para melhora da QV, mas não é preditivo de adesão a programa de II. Nossos achados indicam que intervenção interdisciplinar, ainda que não-direcionada à terapia de distúrbios psiquiátricos, pode auxiliar no controle da depressão e CAP e melhorar a QV / Introduction: Longer life expectancy and high prevalence rates of chronic diseases such as diabetes mellitus (DM) have modified the focus of government health agencies. DM causes severe chronic complications deteriorating quality of life (QoL) and survival; concomitance of DM and psychiatric disorders - such as depression and binge eating (BED) - decreases compliance to treatment and deteriorates prognosis. Management of these disorders may revert in better metabolic control and QoL during programs of lifestyle changes. Objective: To assess whether lifestyle intervention with intensive interdisciplinary approach for individuals at risk for DM results in better QoL that traditional intervention (TI). Methods: 177 individuals with pre-diabetes or metabolic syndrome, seen by Brazilian public health system, were randomly allocated to an IT or intensive intervention (II) in life habits for 9 months. Individuals from TI had medical visits each three months and from II additionally attended 13 psychoeducative group sessions focusing on dietary habits and physical activities. At baseline and after 9 months, they were submitted to clinical examination and laboratory procedures and answered questionnaires: long version of IPAQ, 24-h food recalls, QoL (SF-36), for depression (BDI and PRIME-MD) and binge eating scale. Predictors of compliance defined as attendance >70 per cent of group sessions were analysed by logistic regression. Results: In both interventions, significant improvements in body mass index, waist circumference and HDL-cholesterol levels were observed. After 9 months, only the individuals submitted to II had blood pressure and plasma glucose levels reduced. The same individuals had significant increases in almost all domains and summary measures of the SF-36. Comparing the induced increases in QoL, measures were greater in the domains of physical functioning (II: 11.1 ± 14.0 vs. IT: 13.0 ± 5.3; p = 0.02) and role-emotional (II: 20.4 ± 40.2 vs. IT: 16.2 ± 43.8; p = 0.05) in II in relation to IT. Frequencies of depression reduced in both interventions to 9 months, although of BED decreased only in II (28 to 4 per cent, p <0.001; IT: 13.7 per cent to 8.6 per cent, p = 0.38). Changes in SF-36 correlated inversely and significantly with differences of BMI, waist circumference, systolic blood pressure and glucose levels. Also found was as inverse correlation of QoL scores with depression (r = -0.275, p = 0.001) and BED (r = -0.175, p = 0.043). Logistic regression showed that male gender was independently associated with adherence to II (p = 0.02) but not the presence of BED or depression. Conclusion: Intervention in lifestyle with an interdisciplinary approach induced better benefits for QoL of individuals at risk for DM than the IT, as well as for metabolic profile. The decreased frequencies of the BED and depression following the II may contribute to improvement of QoL, but is not predictive of compliance. Our findings indicate that interdisciplinary intervention for prevention of DM, even not directed to psychiatric disorders, has extrametabolic effects, favoring the control depression and BED and improving QoL
