Disgust sensitivity in eating disorders: a preliminary investigation.

BACKGROUND: Disgust is a basic emotion that has been relatively neglected in psychiatry in general and in eating disorders in particular. Nevertheless, there are features of disgust and its more complex derivatives (e.g., shame) which suggest that disgust may have a role to play in eating disorders. METHOD: Seventy-four patients with a DSM-IV diagnosis of anorexia nervosa, bulimia nervosa, eating disorder not otherwise specified, and obese binge eater were compared with 15 control subjects on their levels of disgust sensitivity. RESULTS: Overall, eating disorder patients did not appear to be more sensitive to disgust-eliciting stimuli than comparison subjects, although there was a tendency for patients to be more disgusted by body products. However, drive for thinness and bulimia scores were related to higher levels of disgust sensitivity to food, death, and magical contagion. General psychopathology did not appear to be related to levels of disgust sensitivity. DISCUSSION: Although patients are not more sensitive than controls to the disgust-eliciting stimuli measured, disgust still has a positive relationship to eating disorder symptoms. Future studies will need to examine more precisely what this relationship might be.

Events and the onset of eating disorders: correcting an "age old" myth.

BACKGROUND: Previous reports have suggested differences between early and late onset cases both in anorexia nervosa and bulimia nervosa. In anorexia nervosa, women with late onset are thought to be more likely to develop symptoms in response to life events than early onset cases. Women developing anorexia in response to life events are also considered to show different background features. In bulimia nervosa, it is not known whether rates of life events before onset differ in bulimics who develop their disorder at different stages in life. METHOD: Previously published data were reanalyzed to examine differences between women whose eating disorder did or did not develop in response to stress. Seventy-two women with anorexia nervosa (48 with a severe provoking agent) and 29 women with bulimia nervosa (22 with a severe provoking agent) were administered semistructured interviews to assess life events and difficulties in the year before onset, childhood adversity, and other clinical features. RESULTS: In both anorexia nervosa and bulimia nervosa, subjects with or without a severe provoking agent did not differ from each other on age or childhood variables. The only significant difference found was that, in women developing anorexia nervosa, those who later developed bulimic symptoms alongside their anorexia reported a lower rate of provoking agents (31%) than those anorexic women who either maintained their restriction (76%) or went on to develop normal weight bulimia nervosa (69%). CONCLUSION: There are no differences between women whose eating disorder develops in response to stress and those who do not. Women presenting for treatment with anorexia nervosa of the binge-purge subtype are unlikely to have developed their illness in response to a severe provoking agent.

Engagement and outcome in the treatment of bulimia nervosa: first phase of a sequential design comparing motivation enhancement therapy and cognitive behavioural therapy.

Despite the major advances in the development of treatments for bulimia nervosa, drop-outs and a lack of engagement in treatment, continue to be problems. Recent studies suggest that the transtheoretical model of change may be applicable to bulimia nervosa. The aim of this study was to examine the roles of readiness to change and therapeutic alliance in determining engagement and outcome in the first phase of treatment. One hundred and twenty five consecutive female patients meeting DSM-IV criteria for bulimia nervosa took part in a randomised controlled treatment trial. The first phase of the sequential treatment compared four sessions of either cognitive behavioural therapy (CBT) or motivational enhancement therapy (MET) in engaging patients in treatment and reducing symptoms. Patients in the action stage showed greater improvement in symptoms of binge eating than did patients in the contemplation stage. Higher pretreatment scores on action were also related to the development of a better therapeutic alliance (as perceived by patients) after four weeks. However, pretreatment stage of change did not predict who dropped out of treatment. There were no differences between MET and CBT in terms of reducing bulimic symptoms or in terms of developing a therapeutic alliance or increasing readiness to change. The results suggest that the transtheoretical model of change may have some validity in the treatment of bulimia nervosa although current measures of readiness to change may require modification. Overall, readiness to change is more strongly related to improvement and the development of a therapeutic alliance than the specific type of treatment.

Stress, coping, and crisis support in eating disorders.

OBJECTIVE: Recent research has supported the role of stress in the development and maintenance of eating disorders. However, coping and crisis support, important aspects of this stress process, have received little systematic attention. The cognitive-transactional approach to coping emphasizes the importance of the relationship between the individual and the particular problematic situation and yet most studies investigating coping in eating disorders have failed to measure situation-specific coping. METHOD: The present study used semistructured interviews to measure coping and crisis support in response to severe events and/or marked difficulties in 12 women with anorexia nervosa (AN), 21 women with bulimia nervosa (BN), and 21 women without an eating disorder (non-ED). RESULTS: Women with eating disorders were more likely to use cognitive avoidance or cognitive rumination and were less likely to downplay their problems. In addition, BN subjects were more likely to blame themselves and were less likely to receive crisis support from a core-tie. Overall, women with eating disorders were less likely to be masterful in response to crises than women without eating disorders. DISCUSSION: It is concluded that women with eating disorders are less effective in their coping than women without eating disorders.

Intriguing links between animal behavior and anorexia nervosa.

OBJECTIVE: The aim of this review is to examine the literature on possible animal models for anorexia nervosa. METHOD: The literature was searched using MedLine, PSYCHLIT, and CAB Abstracts using search items that included body composition, thin sow syndrome, and halothane gene. In addition, key workers in the field of animal husbandry and body composition were sent earlier drafts of the paper for comment. RESULTS: Thin sow syndrome in pigs has some similarities to anorexia nervosa. Leanness and susceptibility to stress are associated in pigs with mutations of the ryanodine gene. Body composition in animals has a high heritability and various components of this overall composite trait are influenced to a major extent by polymorphism at specific gene loci. DISCUSSION: Recent developments in understanding body composition in animals offer intriguing insights into anorexia nervosa and suggest several candidate genes which would be worthy of further examination.

Predictors of outcome for two treatments for bulimia nervosa: short and long-term.

OBJECTIVE: This study examined pretreatment variables to predict outcome in two treatments for bulimia nervosa. METHOD: Patients were offered either 16 weeks of cognitive-behavioral therapy (CBT) or a self-treatment manual followed by up to 8 weeks of CBT (sequential group). Using complete data, stepwise regression analyses were performed. RESULTS: It was found that a longer duration of illness and lower binge frequency predicted a better outcome both at the end of treatment (p < .001) and at 18 months of follow-up (p < .005). In the sequential group, lower pretreatment binge frequency predicted better outcome at the end of treatment (p < .05) and at 18 months of follow-up (p < .05). In the CBT group, longer duration of illness predicted better outcome at the end of treatment (p < .02). DISCUSSION: It is concluded that (1) those with more frequent binging may require a more intense intervention and (2) those who have been ill longer may be more motivated to respond to treatment.

Social support in patients with anorexia nervosa and bulimia nervosa.

OBJECTIVE: To investigate the social support networks of patients with anorexia nervosa (AN) and bulimia nervosa (BN). METHOD: Social support was measured using the Significant Others Scale for 44 patients with AN, 81 patients with BN, and 86 polytechnic students. RESULTS: Eating disorder patients had smaller social networks than the students. AN patients were significantly less likely than BN patients to have a spouse or partner as a support figure. Both AN and BN patients reported less actual emotional and practical support than students. AN patients perceived their social support to be adequate, whereas BN patients were dissatisfied with their support. Patients set lower ideals for support than the students. Social support was not correlated with duration of illness. DISCUSSION: AN and BN patients have deficient social networks. In BN patients there is disturbance in both the size and perceived adequacy of social relationships.

Setting the scene for eating disorders, II. Childhood helplessness and mastery.

BACKGROUND: Previous studies have examined childhood factors that appear to increase the risk of developing an eating disorder (e.g. sexual abuse and parental care). Studies have not yet examined whether the way in which women cope with these adversities in childhood influences the risk. METHOD: Using a semi-structured interview, childhood helplessness and mastery were measured (based on behavioural indices) in women with and without a history of eating disorders. RESULTS: There was a higher rate of childhood helplessness and a lower rate of childhood mastery in women with eating disorders compared to those without. Furthermore, this difference did not appear to be a result of current psychiatric state. CONCLUSION: It is concluded that it is not simply the presence of adversity in childhood which is of aetiological importance in the development of eating disorders but the way in which these are negotiated.

Psychosocial factors in the onset of eating disorders: responses to life-events and difficulties.

A number of studies have proposed a role for stress in the onset of eating disorders. Initially the focus was on the life-events and difficulties themselves. However, the aim of this study was to examine the coping and support elicited in response to the crises that precipitate onset of eating disorders. Thirty-two women who had developed an eating disorder within four years of presentation were administered semi-structured interviews asking about events and difficulties in the year before onset, as well as how they coped and the support they received. Twenty women with no history of eating disorders acted as a comparison group. Results show that the onset of anorexic symptoms is associated with cognitive avoidance in response to a crisis while the onset of bulimic symptoms is associated with cognitive rumination. In addition, women who developed an eating disorder were more likely to be helpless in response to the crisis than women who did not develop an eating disorder. It is concluded that coping interventions may be useful in terms of primary and relapse prevention.

Feelings and fantasy in eating disorders: a factor analysis of the Toronto Alexithymia Scale.

The aim of the study was to examine the factor structure of alexithymia in patients with eating disorders and to compare scores on these factors with a non-eating disordered population. The Toronto Alexithymia Scale (TAS) was given to patients with restricting anorexia nervosa (AN/R, n = 29), bulimia nervosa (BN, n = 83), anorexia with a subtype bulimia (AN/BN, n = 15), and 79 female students. Factors were extracted using a principal-components factor analysis. Four factors were found--inability to Identify Feelings, Paucity of Fantasy, Noncommunication of Feelings, and Concrete Thinking. All three eating disorder groups were less able to identify their feelings than the comparison group and AN/R patients had a more diminished fantasy life than BN patients and students. Groups did not differ significantly on concrete thinking but there was a trend towards significance on noncommunication of feelings, with patient groups expressing their feelings less than comparison subjects. Differences between patient groups on factors of the TAS suggest that scores are not simply a result of psychopathology in general. Approaches which promote the identification and expression of feelings may be particularly useful in the treatment of eating disorders.

Ways of coping in women with eating disorders.

The aim of this study was to investigate the strategies used for coping with stress in eating disorder patients. Twenty-four anorexia nervosa (AN) patients, 66 bulimia nervosa (BN) patients, and 30 female control subjects completed a revised Ways of Coping Checklist, indicating how they dealt with a self-nominated stressor. The AN and BN patients used proportionately more avoidance than control subjects. The BN patients used proportionately more wishful thinking and sought less social support than control subjects but patients with AN did not differ significantly from either BN or control groups. Patient groups did not differ significantly from control subjects on their use of problem-focused coping or self-blame, although the use of problem-focused coping was significantly lower, and self-blame significantly higher, with psychological problems than with relationship and general problems in all groups. Coping failed to predict severity of eating pathology but, in the patient groups, Beck Depression scores were related positively to avoidant coping (avoidance in BN patients and wishful thinking in AN patients) and inversely to problem-focused coping and seeking social support (although the latter just failed to reach significance in the AN group). It is concluded that a treatment approach that teaches coping strategies, as well as removing the obstacles (cognitive, emotional, or practical) that preclude the use of more effective coping, may be a useful component of treatment.

The ultrasonographic features in anorexia nervosa and bulimia nervosa: a simplified method of monitoring hormonal states during weight gain.

Ovarian volume and the diameter of the intra-ovarian follicles correlated with the percentage of premorbid weight in 36 patients with anorexia nervosa who had repeated pelvic ultrasound scans during weight gain. Oestradiol levels increased when the follicles became dominant and were greater than 1 cm in diameter; and uterine growth increased linearly with plasma oestradiol. Pelvic ultrasonography can thus be used as a simple, rapid, bioassay to determine hypothalamic-pituitary-ovarian function in patients with anorexia nervosa and provides a useful guide to the degree of weight restoration required to enable menstrual function to recover. The outcome of anorexia nervosa may be related to the degree to which the biological consequences of starvation which perpetuate the disorder are overcome. The menstrual abnormalities in bulimia nervosa are associated with pelvic ultrasound findings such as small multifollicular ovaries and small uterine areas which also occur in anorexia nervosa and simple weight loss amenorrhoea. This suggests that weight loss or the nutritional disturbance in bulimia nervosa may underlie the menstrual irregularities which commonly occur in this condition.

Weight gain and reproductive function: ultrasonographic and endocrine features in anorexia nervosa.

Pelvic ultrasonographic measurements and reproductive hormone levels in 36 patients with anorexia nervosa were followed as they gained weight during inpatient treatment. In 24 patients who were severely malnourished (69% of premorbid weight) the ovaries were small and amorphous and the levels of LH, FSH and oestradiol were very low. Weight gain led to the appearance of multifollicular ovaries when levels of LH and oestradiol remained low but FSH levels had increased resulting in an LH:FSH ratio of less than 1. The emergence of a dominant follicle in 19 patients after weight gain (to 97% of premorbid weight) was accompanied by an increase in uterine area and associated with increased levels of LH and oestradiol and an LH:FSH ratio greater than 2. Among these patients with a dominant follicle at peak weight, 11 menstruated within a month of discharge. The weight at which normal ovarian morphology returned was related to premorbid weight (P less than 0.002) whereas body mass index (BMI) was poorly related. Our findings suggest that pelvic ultrasonography is probably the best indicator of the weight required for full endocrine recovery and offers advantages over sequential hormonal measurements, and is valuable in the management of patients with anorexia nervosa.
