Validity of the Eating Disorder Examination Questionnaire (EDE-Q) in screening for eating disorders in community samples

In order to examine the concurrent and criterion validity of the questionnaire version of the Eating Disorders Examination (EDE-Q), self-report and interview formats were administered to a community sample of women aged 18-45 (n = 208). Correlations between EDE-Q and EDE subscales ranged from 0.68 for Eating Concern to 0.78 for Shape Concern. Scores on the EDE-Q were significantly higher than those of the EDE for all subscales, with the mean difference ranging from 0.25 for Restraint to 0.85 for Shape Concern. Frequency of both objective bulimic episodes (OBEs) and subjective bulimic episodes (SBEs) was significantly correlated between measures. Chance-corrected agreement between EDE-Q and EDE ratings of the presence of OBEs was fair, while that for SBEs was poor. Receiver operating characteristic (ROC) analysis, based on a sample of 13 cases, indicated that a score of 2.3 on the global scale of the EDE-Q in conjunction with the occurrence of any OBEs and/or use of exercise as a means of weight control, yielded optimal validity coefficients (sensitivity = 0.83, specificity = 0.96, positive predictive value = 0.56). A stepwise discriminant function analysis yielded eight EDE-Q items which best distinguished cases from non-cases, including frequency of OBEs, use of exercise as a means of weight control, use of self-induced vomiting, use of laxatives and guilt about eating. The EDE-Q has good concurrent validity and acceptable criterion validity. The measure appears well-suited to use in prospective epidemiological studies.

The therapeutic alliance: the key to effective patient outcome? A descriptive review of the evidence in community mental health case management

Objective: The aim of this review was to examine the level of evidence supporting the assumed link between a positive therapeutic alliance among patients and case managers and effective outcome for patients with a mental illness who are managed in community mental health services. Method: MedLine, PsychINFO and Social Sciences Index search of articles from 1986 to 2001 returned 84 articles and two texts. Inclusion criteria were the use of validated measures and relevance to psychiatry and community case management. Results: A definite correlation exists in the psychotherapy literature between the therapeutic relationship and improved outcomes, with its potential as a prognostic indicator acknowledged. Attempts to apply the concept to patients outside the field of psychotherapy have been slow, although expansion of the concept to other forms of change-inducing therapy was a current trend. Issues of definition, quantification and measurement of the relationship caused rigorous debate in the literature. Case management research demonstrating the importance of the therapeutic relationship and ‘goodness-of-fit’ between patients and case managers was sparse with no published Australian studies. Conclusions: The level of evidence supporting the link between the therapeutic alliance of patients with mental illness and improved outcomes although sparse is encouraging. It indicates the potential of the alliance as a predictor of outcome for patients engaged in case management services in community mental health. Research to determine the role and effectiveness of the alliance in the patient/case manager dyad is needed to define this potential. Effectiveness of clinical practice in the case management field could be enhanced if research findings confirmed the genesis and value of the alliance in case management. Focus on relationship strategies as a clinical tool gives the clinician and service provider a potential vehicle for promoting partnerships with the seriously mentally ill person in managing their illness and optimizing their strengths in the community.

Assessing quality of life in eating disorder patients

Objective: To examine quality of life among subgroups of eating disorder patients. Method: Self-report questionnaires which included two quality of life measures were completed by 87 individuals referred for treatment to the Australian Capital Territory Eating Disorders Day Program. Health-related quality of life, as measured by the Medical Outcomes Study 12-item Short Form Mental Component Summary scale, and subjective quality of life, as measured by subscales of the World Health Organization Brief Quality of Life Assessment Scale (WHOQOL-BREF), were compared among individuals who received the diagnosis of anorexia nervosa purging subtype (n=15), anorexia nervosa restricting subtype (n=19), bulimia nervosa (n=40) and binge eating disorder (n=10), and among a general population sample of young adult women employed as a control group (n=495). Results: Eating disorder patients, when considered together, showed marked impairment in both health-related and subjective quality of life relative to normal control subjects. However, in both domains, restricting anorexia nervosa patients reported significantly better quality of life than other patient groups, after controlling for levels of general psychological distress. Scores on the Social Relationships subscale of the WHOQOL-BREF among individuals in this subgroup were similar to those of normal control subjects. Conclusions: Reliance on any one instrument is likely to be misleading in assessing the quality of life of eating disorder patients. Careful consideration needs to be given to the assessment of restricting anorexia nervosa patients in particular.

Discerning quality : using the multiple mini-interview in student selection for the Australian National University Medical School

Disordered eating behaviours and cognitions in young women with obesity: relationship with psychological status

Objective:To examine levels of eating disorder behaviours and cognitions of young women with obesity in the Australian Capital Territory, Australia and assess the impact upon psychological status.Design:General population cross-sectional survey.Subjects:A total of 4891 young women from the community aged 18–42 years, of which 630 were in the obese weight range.Measurements:Body mass index (BMI), eating disorder psychopathology (eating disorder examination questionnaire), and psychological distress (K-10).Results:Women with obesity had significantly higher levels of dietary restraint, eating concern, weight concern, shape concern, binge eating, misuse of diuretics, use of diet pills and fasting compared to other women in the community. These eating disorder cognitions and behaviours were associated with increased levels of psychological distress. In women with obesity, eating concern, weight concern, shape concern, dietary restraint and decreased age predicted psychological distress in a multivariate model. Among other women in the community, behaviours such as laxative misuse, ‘hard’ exercise and subjective bulimic episodes also contributed to the model predicting psychological distress.Conclusion:As disordered eating psychopathology is high in young obese women and negatively impacts upon psychological status, obesity prevention and treatment should consider eating disorder psychopathology and mental health outcomes.

Objective and subjective bulimic episodes in the classification of bulimic-type eating disorders: Another nail in the coffin of a problematic distinction

We sought to further explore the validity of the distinction between objective bulimic episodes (OBEs) and subjective bulimic episodes (SBEs) in the study of bulimic-type eating disorders. Drawing on data obtained at the second, interview phase of a large-scale epidemiological study, we identified mutually exclusive subgroups of women with bulimic-type eating disorders who engaged in regular OBEs but not SBEs (n = 37) or regular SBEs but not OBEs (n = 52). These subgroups were compared on a wide range of outcomes, including socio-demographic characteristics, current levels of eating disorder psychopathology, general psychological distress and impairment in role functioning, current and lifetime impairment in quality of life specifically associated with an eating problem, (self)-recognition of an eating problem, health service utilization and use of psychotropic medication. The only difference between groups was that participants who reported regular OBEs were heavier than those who reported regular SBEs. The findings converge with those of previous research in suggesting that bulimic-type eating disorders characterized by regular SBEs, but not OBEs, do not differ in any clinically meaningful way from those characterized by regular OBEs, but not SBEs. Inclusion of bulimic-type eating disorders characterized by regular SBEs as a provisional category requiring further research in DSM-V appears warranted.

Beliefs Of Women Concerning The Severity And Prevalence Of Bulimia Nervosa.

Abstract.Background:Few studies have examined attitudes towards eating-disordered behaviour among women in the general population.Methods:A vignette describing a fictional person meeting diagnostic criteria for bulimia nervosa (BN) was presented to a community sample of women aged 18–45. Respondents (n = 208) were asked a series of questions concerning the severity and prevalence of the problem described.Results:Most respondents viewed BN as a distressing condition whose sufferers are deserving of sympathy. However, more than one-third of respondents had at some stage believed that it ‘might not be too bad’ to be like the person described in the vignette. Most respondents believed that the prevalence of the problem described among women in the community was likely to be between 10 % and 30 % (48.6%) or between 30% and 50 % (23.1 %). Individuals with a clinically significant eating disorder (n = 13, 6.3%) were more likely to perceive the symptoms of BN as being acceptable, and its prevalence higher, than individuals with no eating disorder diagnosis.Conclusions:Information concerning the medical and psychological sequelae of BN and other eating disorders might usefully be incorporated in prevention programmes. Prospective community-based research is required to elucidate the nature of the relationship between perceived acceptability of eating disorder symptoms and actual eating disorder psychopathology. Extension of the present research to examine the views of women in other cultures would also be of interest.

Group interpersonal psychotherapy for postnatal depression: a pilot study

SummaryWe conducted a pilot study to assess the potential effectiveness of group interpersonal psychotherapy (IPT-G) as a treatment for postnatal depression (PND). The study was also established to test a treatment manual for IPT-G, assess the acceptability of this format for participants and test a recruitment strategy for a randomised controlled trial. 18 mothers diagnosed with PND participated in 2 individual session and 8 sessions of group IPT. A two-hour psychoeducational session was also held for the partners of the participants. Measures of depressive symptomatology and social adjustment were administered by an independent clinician at baseline, 4 weeks, 8 weeks and 3 months post treatment. Patient satisfaction with the treatment was also evaluated. Severity scores on the BDI, EPDS and the HDRS decreased from pre- to post-treatment. This was maintained at three months follow up. No overall improvement in the Social Adjustment Scale-Self Report was noted, although there was improvement in their relationship with their significant other. The results confirm previous work that IPT-G may improve symptom severity for women suffering from postnatal depression. Limitations included the use of antidepressant therapy by 67% of subjects and the lack of a control group. There is a need for further randomised controlled trials of IPT-G with larger sample sizes to establish its effectiveness as treatment for PND.

Obesity and Impairment in Psychosocial Functioning in Women: The Mediating Role of Eating Disorder Features

Objective: The objective was to test the hypothesis that, in women, the association between obesity and impairment in psychosocial functioning is mediated by levels of weight and shape concerns and/or binge‐eating frequency.

Posttraumatic stress disorder: an exploratory study examining rates of trauma and PTSD and its effect on client outcomes in community mental health

BackgroundRates of trauma and Posttraumatic Stress Disorder (PTSD) were examined in order to compare the profile in clients of an Australian Public Mental Health Service with that reported in the international literature for clients with major mental illness and to explore the effect of this on client health outcomes. Potential factors contributing to increased levels of trauma/PTSD in this group of clients and the issue of causality between PTSD and subsequent mental illness was also explored.MethodsA convenience sample of 29 clients was screened for trauma and PTSD using the Posttraumatic Stress Diagnostic Scale™ (PDS) and selected outcome measures. Paired and independent samples t-test and ANOVA were applied to the data.ResultsHigh levels of undocumented trauma and PTSD were found. Twenty clients, (74%) reported exposure to multiple traumatic events; 33.3% (9) met DSM IV diagnostic criteria for PTSD. Significant difference was found for PTSD symptomatology, severity and impairment and for client and clinician-rated scores of Quality of Life (QOL) outcomes in the PTSD group. No effect for PTSD symptomatology on the Working Alliance (WA) was found. Factors that may influence higher rates of PTSD in this group were identified and included issues associated with the population studied, the predominance of assaultive violence found, and vulnerability and risks factors associated with re-traumatisation within the social and treating environments.ConclusionA similar trauma and PTSD profile to that reported in the international literature, including greater levels of trauma and PTSD and a poorer QOL, was found in this small sample of clients. It is postulated that the increased levels of trauma/PTSD as reported for persons with major mental illness, including those found in the current study, are primarily related to the characteristics of the population that access public mainstream psychiatric services and that these factors have specific implications for service delivery, and raise issues of efficiency and effectiveness of resource use in achieving successful outcomes in public mental health services for clients with co-morbid PTSD. Further research with a more rigorous design is needed to test these preliminary findings within Australian Community Mental Health Services.
