Maintenance of internet-based prevention: a randomized controlled trial.

OBJECTIVE: Excessive weight or shape concerns and dieting are among the most important and well-established risk factors for the development of symptoms of disordered eating or full-syndrome eating disorders. Prevention programs should therefore target these factors in order to reduce the likelihood of developing an eating disorder. The aims of this study were to determine the short-term and maintenance effects of an internet-based prevention program for eating disorders. METHOD: One hundred female students at two German universities were randomly assigned to either an 8-week intervention or a waiting-list control condition and assessed at preintervention, postintervention, and 3-month follow-up. RESULTS: Compared with the control group, the intervention produced significant and sustained effects for high-risk women. CONCLUSION: Internet-based prevention is effective and can be successfully adapted to a different culture.

[Pathological buying -- a literature review].

This review summarizes the literature on pathological buying published during the past 15 years. Pathological or compulsive buying is defined as frequent preoccupation with buying or impulses to buy that are experienced as irresistible, intrusive, and/or senseless. The buying behavior causes marked distress, interferes with social functioning, and often results in financial problems. Studies on the phenomenology, diagnosis, classification, comorbidity, epidemiology, and treatment are presented. Pathological buying should be diagnosed as impulse control disorder not otherwise specified (ICD-10 F63.9). Psychiatric comorbidity is frequent, particulary mood, anxiety, substance use, eating, impulse control and obsessive-compulsive disorders. The positive results of pharmacological treatment with antidepressants (usually SSRI) and opioid antagonists could not be confirmed in controlled trials. A disorder specific cognitive-behavioral group treatment manual was published in USA. A controlled study is currently conducted in USA and since 2003 at the Department of Psychosomatics and Psychotherapy at the University Hospital Erlangen.

[Cognitive-behavioral psychotherapy for adolescents with eating disorders].

Anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) are grouped together under the term eating disorders. Due to its typical onset in adolescence, AN in particular represents a frequent disorder with often an unfavourable course in this age range (Steinhausen 2002). The mental, social and physical consequences are serious. Research has shown that cognitive-behavioral treatment (CBT) has good effectiveness in adult patients with AN, BN and BED and that it is superior to other treatments. However, there have been few studies on children and adolescents. The effectiveness in adolescence can thus be judged only when the results in adulthood are taken into account. At present, there is limited evidence for the effectiveness of CBT in adolescence.

Specificity of self-concept disturbances in eating disorders.

OBJECTIVES: The current study examined self-concept deficits among three diagnostic groups of eating-disordered patients, evaluated the relationship between self-concept deficits and depression, and addressed the specificity of self-concept deficits in eating-disordered patients. METHOD: Three groups of eating-disordered patients (anorexia nervosa, N = 33; bulimia nervosa, N = 38; binge eating disorder, N = 28) were first compared to three matched healthy control groups and then to two psychiatric comparison groups (patients with anxiety disorders, N = 37; patients with depressive disorders, N = 37). RESULTS: All three groups of eating-disordered patients displayed lower self-esteem and higher feelings of ineffectiveness compared with the healthy controls, even after controlling for depression. Differences in self-esteem and ineffectiveness were also found between eating-disordered patients and psychiatric controls. However, not all of the differences were significant. In addition, the psychiatric controls also exhibited lower self-esteem than normative samples. DISCUSSION: Findings suggest that self-concept deficits are more pronounced in eating-disordered patients but cannot be regarded as highly specific.

Screening for eating disorders and high-risk behavior: caution.

OBJECTIVE: The current study reviews the state of eating disorder screens. METHODS: Screens were classified by their purported screening function: identification of cases with (a) anorexia nervosa only; (b) bulimia nervosa only; (c) eating disorders in general; (d) partial syndrome, eating disorder not otherwise specified (EDNOS), or subclinical; (e) not a-d but at high risk. Information is presented on development, psychometric properties, and external validation (e.g., sensitivity, specificity, positive predictive values, and negative predictive values). RESULTS: Screens differ widely with regard to objective, psychometric properties and the validation methodology used. Most screens that identify cases are not appropriate for the identification of at-risk behaviors. Little data on the external validity of screens are available. DISCUSSION: Screens should be used with caution. A sequential procedure, in which subjects identified as being at risk during the first stage is followed by more specific diagnostic tests during the second stage, might overcome some of the limitations of the one-stage screening approach.

Coming to terms with risk factors for eating disorders: application of risk terminology and suggestions for a general taxonomy.

The aims of the present review are to apply a recent risk factor approach (H. C. Kraemer et al., 1997) to putative risk factors for eating disorders, to order these along a timeline, and to deduce general taxonomic questions. Putative risk factors were classified according to risk factor type, outcome (anorexia nervosa, bulimia nervosa, binge-eating disorder, full vs. partial syndromes), and additional factor characteristics (specificity, potency, need for replication). Few of the putative risk factors were reported to precede the onset of the disorder. Many factors were general risk factors; only few differentiated between the 3 eating disorder syndromes. Common risk factors from longitudinal and cross-sectional studies were gender, ethnicity, early childhood eating and gastrointestinal problems, elevated weight and shape concerns, negative self-evaluation, sexual abuse and other adverse experiences, and general psychiatric morbidity. Suggestions are made for the conceptualization of future risk factor studies.

Behavioral validation, precursors, and concomitants of picky eating in childhood.

OBJECTIVES: To validate the concept of parent-reported picky eating using objective, laboratory-based measures and to identify both child and parental precursors and concomitants of picky eating. METHOD: One hundred thirty-five infants were monitored from birth to 5.5 years. Behavioral measures of picky eating were obtained from standardized feedings at ages 3.5 and 5.5 years in the laboratory and at home. Child precursors were measures of infant sucking behavior; parental precursors were disinhibition of eating, restrained eating, body dissatisfaction, and body mass index. Parentally reported attitudes and behaviors thought to be related to pickiness and parental concomitants were taken from the Stanford Feeding Questionnaire. Child Temperament was assessed by the Children's Behavior Questionnaire. RESULTS: Picky eaters ate fewer foods and were especially more likely to avoid vegetables. Picky girls decreased their caloric intake between ages 3.5 and 5.5, whereas all other children increased their caloric intake. None of the included parental precursors was significantly related to pickiness. Picky eaters demonstrated a different sucking pattern with fewer sucks per feeding session at weeks 2 and 4. Finally, picky children displayed more parent-reported negative affect than nonpicky children. CONCLUSIONS: Parentally reported picky eating is associated with a consistent pattern of inhibited and selective eating beginning in infancy.

Are obese adolescents and young adults at higher risk for mental disorders? A community survey.

OBJECTIVE: Associations between body mass index (BMI) and mental disorders meeting Axis-I diagnoses according to the Diagnostic and Statistical Manual for Mental Disorders IV (DSM-IV) were investigated in The Early Developmental Stages of Psychopathology Study in a large population-based sample, which included adolescents and young adults of both genders for the first time. RESEARCH METHODS AND PROCEDURES: A total of 3021 German subjects ranging from 14 to 24 years of age were assessed for specific DSM-IV diagnoses derived from a modified version of the standardized Composite International Diagnostic Interview, and general psychological disturbances, using the Symptom Checklist-90-Revised. BMI percentiles for age and gender were calculated to avoid systematic bias in the BMI distribution resulting from the young age range represented in the sample. Additionally, subjects with a lifetime diagnosis of any eating disorder were excluded from statistical analysis to control the confounding effect of body weight-related eating disorders on associations between BMI and psychopathology. RESULTS: The results based on logistic regression analyses and MANOVAs demonstrate that the BMI is not associated with mental disorders or general psychopathologies. There were no significant associations between BMI and mood, anxiety, substance, and somatoform disorders, a result that contrasts with almost all previous clinical studies. Additionally, in contrast to clinical investigations and most epidemiological studies, neither obesity nor underweight was significantly associated with any kind of general psychopathology. DISCUSSION: The overall finding that obesity is not significantly related to marked psychopathology in the general German population of adolescents and young adults has important clinical implications.
