Internet-Based Cognitive-Behavioral Therapy for Bulimia Nervosa: A Controlled Study

Imaging of Eating Disorders: Multiple Techniques to Demonstrate the Dynamic Brain

This study sought to determine if rates of childhood sexual, physical, psychological, and multiple abuse (i.e., abuse in more than one form) differed between women with a lifetime history of bulimia nervosa and women with no history of eating disorders. Subjects were 80 women, aged 18-35, with a lifetime history of bulimia nervosa (40 women who had recovered for a year or more and 40 women currently suffering from bulimia nervosa) and 40 women who had never had an eating disorder or related difficulties. The cohort was obtained primarily by newspaper advertisement. Subjects participated in structured diagnostic interviews and completed paper-and-pencil questionnaires related to abusive experiences in childhood. Women in the bulimia nervosa group reported higher levels of childhood physical, psychological, and multiple abuse. Contrary to expectation, rates of sexual abuse did not distinguish the groups, except in combination with other forms of abuse. The higher rates of psychological, physical, and multiple abuse found among women with a lifetime history of bulimia nervosa than among comparison subjects underscore the importance of examining the full range of possible abusive experiences in women with eating disorders, rather than focusing simply on sexual abuse.

Eating disorders are multifaceted psychopathologies and the transdiagnostic approach is currently considered a useful framework to understand their complexity. This preliminary study aimed to investigate both broad (i.e., intolerance of uncertainty and emotion dysregulation) and narrow (i.e., extreme body dissatisfaction) transdiagnostic risk factors underlying eating disorders. 50 Italian female patients seeking treatment for an eating disorder were involved (Mage = 31.6 years ± 12.8, 18–65). They completed self-report measures assessing emotion regulation difficulties, intolerance of uncertainty, extreme body dissatisfaction, general psychological distress, and eating disorder symptomatology. To explore whether the abovementioned transdiagnostic factors predicted patients’ psychological distress and eating disorder symptoms, two linear regressions were performed. Emotion dysregulation emerged as the only significant predictor of distress, while extreme body dissatisfaction was the only significant predictor of overall eating disorder symptomatology. Then, to analyze the differences between patients with anorexia nervosa and bulimia nervosa in intolerance of uncertainty and emotion regulation problems, t-tests were conducted. The two groups differed significantly in intolerance of uncertainty levels only, with higher scores obtained by patients with anorexia nervosa. Overall, our findings suggest that emotion dysregulation and extreme body dissatisfaction may be relevant constructs in eating disorders in general, while intolerance of uncertainty may be more involved in restrictive eating disorders. The clinical implications of such results are discussed.

Eating disorders (EDs), especially anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) often co-occur with suicidal behaviour and non-suicidal self-injury (NSSI). The shared epidemiological and risk factors of EDs, suicidal behaviour, and NSSI include the self-destructive and body-focused characteristics of these behaviours; body dissatisfaction, interoceptive deficits, emotion dysregulation, impulsivity, and several environmental risk factors. Compared to the general population, lifetime rates of suicidal ideation, suicide attempts, and NSSI are increased among patients with AN, BN, or BED. Risk factors play a role in the development of suicidal behaviour in patients with EDs, including comorbid psychopathology that is associated with an increased risk of suicide itself, increased impulsive behaviours including NSSI, the duration of illness, and the number of previous treatments. Being aware of the increased risk and the ED-specific risk factors of suicidal behaviour are essential for preventing suicide and treating clinical risk factors in patients with EDs.

Eating Disorders: What Are the Risks?

The characteristics of anorexia nervosa and bulimia nervosa were studied in ballet dancers in full-time training and compared with other young women at school. Dancers had higher scores on the Eating Attitudes Test. Dancers were more likely to have an eating disorder when strict modified DSM-3-R criteria were applied. Currently 1 dancer (1.6%) and no student had anorexia nervosa, 1 dancer (1.6%) and 3 students (1.3%) had bulimia nervosa and 5 dancers (8.3%) and 9 students (4.2%) had an unclassified eating disorder. Another dancer had been treated for anorexia nervosa in the past. One dancer was treated for bulimia nervosa and 6 for weight loss. Dancers were more likely to have been told to increase their body weight. Dancers were not more likely to be afraid of losing control of their weight and becoming obese if they attempted weight gain, to ignore the advice to gain weight or resist gaining weight. Regular self-induced vomiting was reported by 4% of women. Dancers are at risk for the development of eating disorders. Ballet dancers are under pressure to maintain low body weight. The low body weight and menstrual disturbance found among young dancers during training are two of the characteristics of anorexia nervosa Ballet dancers use behaviours aimed at weight control and weight loss. In dancers and professional groups under intense pressure to diet, low body weight and amenorrhoea are not sufficient criteria to diagnose anorexia nervosa. These behaviours can result in binge eating and multiple behaviours aimed at preventing binge eating. Whether the characteristics of bulimia among dancers are sufficient for a diagnosis of bulimia nervosa to be made is unknown. The aim of this paper is to study the characteristics of the eating disorders anorexia nervosa, bulimia nervosa and eating disorder not otherwise specified among young ballet dancers in full-time ballet training and to provide information about the risk of development of eating disorders among young women required to maintain below average body weight while continuing above average exercise.

We report on the long-term outcome of males compared to females treated for anorexia nervosa (AN) or bulimia nervosa (BN). A total of 119 males with AN and 60 males with BN were reassessed 5.8 ± 4.6 and 7.5 ± 5.9 years (respectively) after treatment and compared to matched female patients. At follow-up, males with AN had a higher body weight than females. For AN, remission rates (40% males vs. 41% females) did not differ at follow-up. And at follow-up, more males (34%) than females (19%) had an eating disorder not otherwise specified (ED-NOS; p < .01). At follow-up of AN, there was no binge-eating disorder (BED) and obesity was rare. For BN, remission rates (44% males vs. 50% females) and frequency of AN, BN, BED and ED-NOS did not differ at follow-up. Males with AN scored lower than females at follow-up on most subscales of the Eating Disorder Inventory (EDI) and on somatization, obsessive-compulsive symptoms, and depression (Brief Symptom Inventory). Males with BN scored lower than females with BN on perfectionism and higher on interpersonal distrust (EDI) at follow-up. Results from the scarce literature on males with ED are inconclusive regarding longer term outcome. In the present study, males with AN showed a slightly better outcome than females. In BN, outcome was about the same in males and females. According to our study, existing treatment is equally effective in both males and females. Additional research on the need of gender-specific diagnosis and therapy is required.

In individuals undergoing different intensities of outpatient treatment for an eating disorder, we sought to assess associations between autonomous and controlled motivations and response to treatment on the one hand, and likelihood of dropping out of treatment, on the other. Seven hundred seventy adults meeting DSM-5 criteria for an eating disorder (216 with Anorexia Nervosa, 282 with Bulimia Nervosa, and 272 with Other Specified Feeding or Eating Disorder) were included in this study. Before an interval of outpatient treatment, individuals completed the Eating Disorder Examination Questionnaire and the Autonomous and Controlled Motivations for Treatment Questionnaire. Participants completed the Eating Disorder Examination Questionnaire again at one or two subsequent timepoints. After controlling for diagnosis, treatment intensity, and number of previous treatments, analyses showed that higher autonomous motivation was associated with better response on eating-disorder overall symptoms and lower likelihood of dropping out of treatment. In contrast, controlled motivation was not associated with response to treatment. Our results suggest that autonomous motivation has trans-diagnostic influence upon response to various intensities of treatment for an eating disorder. In support of an autonomy supportive approach to treatment, findings link autonomous motivation with more favorable outcome.

Selective processing of linguistic and pictorial food stimuli in females with anorexia and bulimia nervosa

Many believe that the current application of modern logistics solutions in general and centralisation of distribution systems in particular is damaging from an environmental perspective. The reason for this claim is that when a distribution system is centralised, products need to be shipped over greater distances. This causes an increase in transport work, which in turn is believed to cause an increase in emissions. Further, the decision to centralise distribution can be characterised as a structural decision and earlier research has helped illustrate how such decisions have greater impact on the overall performance of a distribution system than decisions taken at subsequent levels (tactical and operative). The reason for this is that structural decisions help create new opportunities to make other logistical decisions that are beneficial for the performance of a distribution system, as measured in terms of costs and service. It is also acknowledged that there is a lack of research illustrating the actual environmental effects of centralisation. This area is the theme of this thesis and the overall purpose is to describe and analyse how centralisation of a distribution system can affect the environment. This purpose has been divided into two research questions, where the first one reads: - How does physical centralisation of a distribution system influence the environment? This question aims at investigating what effect centralisation has on the amount of emissions that are caused by transport in a distribution system. One of the main advantages with a centralised distribution system is that emergency deliveries are expected to decrease. This type of transport is often performed by airfreight, which is a mode of transport that is regarded to cause the largest amount of environmental stress among the four most commonly used transport modes. The argument that is made is that even though centralisation causes an increase in transport work, this must not necessarily mean that emissions increase. As indicated above, earlier studies on structural changes in distribution systems have shown that this type of decision creates new opportunities to make other decisions that are beneficial for the performance of a distribution system, albeit in terms of costs and service. The aim of the second research question is consequently to study this issue, but from an environmental perspective. This question therefore reads: - How do structural decisions in logistics create new opportunities to improve on the environmental performance of a distribution system? The results of the study show that it is not sufficient to only consider transport work and emergency deliveries when the environmental effect of a centralisation is to be evaluated. It has also been concluded that centralisation creates an opportunity to make improvements within the distribution system that can prove beneficial from an environmental perspective. In summary, three characteristics besides transport work and emergency deliveries were identified as being of importance when considering the environmental effects of a centralisation. These included centralised flow, modal change, and bargaining power. This model (see full pdf) does not aim to include all characteristics that can be relevant in an environmental evaluation of a centralisation, but rather those that have been found significant in this study. However, the model helps illustrate that there are many aspects that need to be considered in such an evaluation and that depending on the characteristics of the distribution system at hand the results can vary quite extensively.

Variables such as severe symptoms, comorbidity, and sociodemographic characteristics (eg, low educational attainment or unemployment) are associated with a poorer prognosis in adults treated for depressive symptoms. The exclusion of patients with a poor prognosis from RCTs is negatively associated with the generalizability of research findings. To compare the prognostic risk factors (PRFs) in patient samples of RCTs of face-to-face therapy (FTF) and internet-based therapy (IBT) for depression. PsycINFO, Cochrane CENTRAL, and reference lists of published meta-analyses were searched from January 1, 2000, to December 31, 2021. RCTs that compared FTF (individual or group therapy) and IBT (guided or self-guided interventions) against a control (waitlist or treatment as usual) in adults with symptoms of depression were included. Data were extracted by 2 independent observers. The Cochrane revised risk-of-bias tool was used to assess the risk of bias. The study was preregistered with OSF Registries and followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. The primary outcome was the standardized mean difference (Hedges g effect size) in depressive symptoms at treatment termination (assessed with standard patient self-report questionnaires), with a positive standardized mean difference indicating larger improvements in the intervention compared with those in the control group. Meta-regression analyses were adjusted for the type of control group. Three preregistered and 2 exploratory sensitivity analyses were conducted. A prognostic risk index (PROG) was created that calculated the sum of 12 predefined individual indicators, with scores ranging from 0 to 12 and higher scores indicating that a sample comprised patients with poorer prognoses. This systematic review and meta-regression analysis identified 105 eligible RCTs that comprised 18 363 patients. In total, 48 studies (46%) examined FTF, and 57 studies (54%) examined IBT. The PROG was significantly higher in the RCTs of FTF than in the RCTs of IBT (FTF: mean [SD], 3.55 [1.75]; median [IQR], 3.5 [2.0-4.5]; IBT: mean [SD], 2.27 [1.66]; median [IQR], 2.0 [1.0-3.5]; z = -3.68, P < .001; Hedges g = 0.75; 95% CI, 0.36-1.15). A random-effects meta-regression analysis found no association of the PROG with the effect size. Sensitivity analyses with outliers excluded and accounting for risk of bias or small-study effects yielded mixed results on the association between the PROG and effect size. The findings of this systematic review and meta-regression analysis suggest that samples of RCTs of FTF vs IBT differ with regard to PRFs. These findings have implications for the generalizability of the current evidence on IBT for depression. More RCTs of internet-based interventions with clinically representative samples are needed, and the reporting of PRFs must be improved.

Elements of family dynamics have been shown to be related to onset, course, as well as prognosis of anorexia nervosa and bulimia nervosa. The goal was to explore the experience of family relations in a group of patients with eating disorders using a projective family test. The Patient group (anorexia=21, bulimia=16), as well as a healthy Control group, were given a projective family test, the Eating Disorder Inventory-2, as well as Karolinska Scales of Personality. The Patient group expressed more discord within the family picture than the Control group, such as cold and loveless relationships and not feeling validated. The group of patients reporting the most family discord did not show more eating disorder pathology or general psychopathology. They did, however, have higher scores on the Eating Disorder Inventory-2 subscale Maturity Fears, as well as higher values on the Karolinska Scales of Personality subscale Socialization. These results are interpreted within the background of methodological challenges in this area of research.

BackgroundOne of the main problems of Internet-delivered interventions for a range of disorders is the high dropout rate, yet little is known about the factors associated with this. We recently developed and tested a Web-based 6-session program to enhance motivation to change for women with anorexia nervosa, bulimia nervosa, or related subthreshold eating pathology.ObjectiveThe aim of the present study was to identify predictors of dropout from this Web program.MethodsA total of 179 women took part in the study. We used survival analyses (Cox regression) to investigate the predictive effect of eating disorder pathology (assessed by the Eating Disorders Examination-Questionnaire; EDE-Q), depressive mood (Hopkins Symptom Checklist), motivation to change (University of Rhode Island Change Assessment Scale; URICA), and participants’ age at dropout. To identify predictors, we used the least absolute shrinkage and selection operator (LASSO) method.ResultsThe dropout rate was 50.8% (91/179) and was equally distributed across the 6 treatment sessions. The LASSO analysis revealed that higher scores on the Shape Concerns subscale of the EDE-Q, a higher frequency of binge eating episodes and vomiting, as well as higher depression scores significantly increased the probability of dropout. However, we did not find any effect of the URICA or age on dropout.ConclusionsWomen with more severe eating disorder pathology and depressive mood had a higher likelihood of dropping out from a Web-based motivational enhancement program. Interventions such as ours need to address the specific needs of women with more severe eating disorder pathology and depressive mood and offer them additional support to prevent them from prematurely discontinuing treatment.
