Discriminant function analysis of depressive symptoms in binge eating disorder, bulimia nervosa, and major depression

Depressive dimensions and item response analysis of the Hamilton Depression Rating Scale-17 in eating disorders

BACKGROUND

Most patients having eating disorders (EDs) experience depressive symptoms. To date, there have been few reports about the different depressive dimensions in EDs.

OBJECTIVE

The aim of this study was to investigate the dimensions of depressive symptoms and highlight the distribution of the symptoms. The psychometric properties of these measures were tested using item response theory methods.

METHODS

A total of 103 consecutively admitted inpatients and outpatients who met the Diagnostic and Statistical Manual of Mental Disorders, Revised Fourth Edition, criteria for anorexia nervosa, bulimia nervosa, and EDs not otherwise specified were rated with the Hamilton Depression Rating Scale (HDRS-17). A factor analysis of the HDRS-17 was carried out with the Cf-varimax rotation.

RESULTS

Factor analysis showed 2 independent and clinically interpretable factors corresponding to "anxious depression" and "somatic complaints" that constituted the core of depression. For the HDRS-17, item response theory analyses revealed that most of the items were maximally related to the core concept of depression and provided a good functioning. The 17 items were distributed in almost the same way as in the factor analyses found by other authors with different clinical groups. We conclude therefore that for the sample of EDs, 2 factors constitute the core symptoms of depression and most of the items provided a good functioning.

Examining the relationship between dietary restraint and binge eating: differential effects of major and minor stressors

This study sought to examine the complex interactive impact of major stress and minor stressors on the relation between dietary restraint and binge eating. Participants were 497 undergraduate females who completed an online questionnaire that included measures of binge eating (modified version of the bulimia scale of the Eating Disorder Inventory-2; EDI-2), major life stressors (the Social Readjustment Rating Scale; SRRS), minor stressors (Daily Stress Inventory; DSI), and dietary restraint (Restraint Scale; RS). A hierarchal linear regression revealed a significant three-way interaction among dietary restraint, life event stress, and daily stress that accounted for a significant proportion of the variance in binge eating above and beyond all main effects and two-way interactions. Findings suggested that the interactive relationship among dietary restraint and daily stress is present only under conditions of high life event stress. Overall, the relationship between dietary restraint and binge eating appears to be quite complex and dependent upon differential levels of daily and life event stressors.

Symptom profile of major depressive disorder in women with eating disorders

OBJECTIVE

Based on the well-documented association between eating disorders (EDs) and affective disorders, the patterns of comorbidity of EDs and major depressive disorder (MDD) were investigated. The temporal relation between EDs and MDD onset was analyzed to determine differences in the course and nature of MDD when experienced prior to versus after the onset of the ED.

METHOD

Lifetime MDD and depressive symptoms were assessed in 1371 women with a history of ED. The prevalence of MDD was first explored across ED subtypes, and ages of onset of MDD and EDs were compared. Depressive symptoms were examined in individuals who developed MDD before and after ED onset.

RESULTS

The lifetime prevalence of MDD was 72.9%. Among those with lifetime MDD (n =963), 34.5% reported MDD onset before the onset of ED. Those who experienced MDD first reported greater psychomotor agitation (OR =1.53; 95%CI =1.14-2.06), and thoughts of own death (but not suicide attempts or ideation; OR =1.73; 95%CI =1.31-2.30). Among individuals who had MDD before ED, 26.5% had the MDD onset during the year before the onset of ED; 67% of individuals had the onset of both disorders within the same 3 year window.

CONCLUSION

Clinicians treating individuals with new-onset ED or MDD should remain vigilant for the emergence of additional psychopathology, especially during the initial 3 year window following the onset of the first disorder.

An empirical comparison of atypical bulimia nervosa and binge eating disorder

The International Classification of Diseases, 10th edition (ICD-10) defines atypical bulimia nervosa (ABN) as an eating disorder that encompasses several different syndromes, including the DSM-IV binge eating disorder (BED). We investigated whether patients with BED can be differentiated clinically from patients with ABN who do not meet criteria for BED. Fifty-three obese patients were examined using the Structured Clinical Interview for DSM-IV and the ICD-10 criteria for eating disorders. All volunteers completed the Binge Eating Scale (BES), the Beck Depression Inventory, and the Symptom Checklist-90 (SCL-90). Individuals fulfilling criteria for both ABN and BED (N = 18), ABN without BED (N = 16), and obese controls (N = 19) were compared and contrasted. Patients with ABN and BED and patients with ABN without BED displayed similar levels of binge eating severity according to the BES (31.05 +/- 7.7 and 30.05 +/- 5.5, respectively), which were significantly higher than those found in the obese controls (18.32 +/- 8.7; P < 0.001 and P < 0.001, respectively). When compared to patients with ABN and BED, patients with ABN without BED showed increased lifetime rates of agoraphobia (P = 0.02) and increased scores in the somatization (1.97 +/- 0.85 vs 1.02 +/- 0.68; P = 0.001), obsessive-compulsive (2.10 +/- 1.03 vs 1.22 +/- 0.88; P = 0.01), anxiety (1.70 +/- 0.82 vs 1.02 +/- 0.72; P = 0.02), anger (1.41 +/- 1.03 vs 0.59 +/- 0.54; P = 0.005) and psychoticism (1.49 +/- 0.93 vs 0.75 +/- 0.55; P = 0.01) dimensions of the SCL-90. The BED construct may represent a subgroup of ABN with less comorbities and associated symptoms.

Women's experiences of bulimia nervosa

AIM

This paper reports a study to interpret and understand bulimia nervosa as women experience it.

BACKGROUND

Research into bulimia nervosa has focused on prevalence rates, health complications, comorbidity, neurochemical dysregulation, and cultural influences. Despite a multitude of investigations, little published research appraised bulimic women's personal experiences and understanding of this disorder. Such an understanding would assist health care professionals in providing sensitive, empathetic care.

METHOD

The principles of Heideggerian phenomenology guided the study. Participants were 13 actively bulimic women, aged 18-36 years, with lengths of illness from 1 to 23 years. Data were obtained through interviews, personal diaries, and demographic questionnaires.

FINDINGS

Participants' narratives revealed four themes that characterized the experience of living with bulimia: isolating self, living in fear, being at war with the mind, and pacifying the brain. The practices bulimic women engage in are carried out in secret, and hence participants experienced isolation. Binge eating and self-induced vomiting are considered abnormal behaviours; therefore, participants believed that they were subjected to negative public perceptions, which led to the experience of living in fear. The women feared being judged if others knew about the disorder. Several feared living without bulimia because it had become a significant part of their identity. In addition, these women were terrified of gaining weight or becoming fat. They experienced an internal struggle with the mind. In order to pacify the inner voice, many fed the compulsion to eat, and this resulted in guilt. The women subsequently balanced the experience by getting rid of fullness and erasing guilt, which was primarily achieved through self-induced vomiting.

CONCLUSIONS

Understanding the experience of bulimia for women who suffer from this disorder is important. Bulimia often presents as a chronic and potentially lifelong health issue. Awareness of bulimic women's perspectives could promote a comprehensive appreciation of bulimia, its aetiology, and directions for treatment alternatives.

Interest of pronostic score for optimal clinical management of obese patients

OBJECTIVE

The aim of this retrospective study was to identify key factors favoring weight regain.

METHODS

Therefore, prognostic factors for weight loss and regain have been retrieved and identified among 186 obese patients (40 +/- 2 y and 34 +/- 0.3 kg/m(2)) through the use of a simple questionnaire which considered psychological issues such as depression, anxiety and the patient's individual capacity to follow a diet. All patients have been prescribed a low-calorie diet (1200 kcal/day) being either balanced, food-combining or low-CHO. Follow-up averaged 6.4 +/- 0.3 months of which weight loss accounted for 4.4 +/- 0.1 months.

RESULTS

Weight loss was similar in all 3 groups and averaged 6.0 +/- 0.2 kg. The final weight loss and weight regain results have been identical for the 3 groups. A high/bad prognostic score rating is associated with weight regain (P<0.02). Weight regain is significantly influenced by the initial weight loss speed (P<0.0001).

CONCLUSIONS

The proposed prognostic score is likely to be helpful for clinicians better to profile the therapeutic approach to individualized obesity management and follow-up. Diet composition does not influence either weight loss or weight regain.
