Factors influencing the duration of untreated illness among patients with anorexia nervosa: A multicenter and multi-informant study.

INTRODUCTION: The duration of untreated illness (DUI), that is, the interval between the onset of anorexia nervosa (AN) symptoms and start of specialized treatments, has a strong influence on the prognosis. OBJECTIVE: To quantify modifiable predictors of the DUI and to derive recommendations for secondary prevention strategies. METHODS: Within a multicenter, multi-informant study, DUI was assessed in interviews with patients undergoing first specialized AN treatment. Modifiable factors were assessed perspectives of AN-patients, their relatives, and primary care practitioners [PCPs]) with the FABIANA-checklist (Facilitators and barriers in anorexia nervosa treatment initiation). The effect of FABIANA-items on the DUI for each perspective was calculated using Cox Regression (control variables: age, eating disorder pathology, health care status, migration background, body mass index [BMI]). RESULTS: We included data from N = 125 female patients with AN (72 adults, 53 adolescents, Mage = 19.2 years, SD = 4.2, MBMI = 15.7 kg/m2 , SD = 1.9), N = 89 relatives (81.8% female, 18.2% male, Mage = 46.0 years, SD = 11.0) and N = 40 PCPs (Mage = 49.7 years, SD = 9.0). Average DUI was 12.0 months. Watching or reading articles about the successful treatment of other individuals with AN (patients' perspective) and regular appointments with a PCP (PCPs' perspective) were related to a shorter DUI (HR = 0.145, p = .046/ HR = 0.395, p = .018). Patients whose relatives rated that PCPs trivialized patients' difficulties had a longer DUI (HR = -0.147, p = .037). PCPs and relatives rated PCPs' competence higher than patients did. DISCUSSION: It is recommended (a) to incorporate treatment success stories in prevention strategies, (b) to inform PCPs about potential benefits of regular appointments during the transition to specialized care, and (c) to train PCPs in dealing with patients' complaints. PUBLIC SIGNIFICANCE: Many individuals with AN seek treatment very late. Our study shows that a promising approach to facilitate earlier AN treatment is to inform patients about successful treatments of affected peers, to foster regular appointments with a PCP and, to motivate these PCPs to take individuals' with AN difficulties seriously. Thus, our study provides important suggestions for interventions that aim to improve early treatment in AN.

Reduced emotion recognition from nonverbal cues in anorexia nervosa.

OBJECTIVE: Recent models of anorexia nervosa (AN) emphasise the role of reduced emotion recognition ability (ERA) in the development and maintenance of the disorder. However, methodological limitations impede conclusions from prior research. The current study tries to overcome these limitations by examining ERA with an audio-visual measure that focuses strictly on multimodal nonverbal cues and allows to differentiate between ERA for different emotion categories. METHOD: Forty women with AN and 40 healthy women completed the Geneva Emotion Recognition Test. This test includes 83 video clips in which 10 actors express 14 different emotions while saying a pseudo-linguistic sentence without semantic meaning. All clips contain multimodal nonverbal cues (i.e., prosody, facial expression, gestures, and posture). RESULTS: Patients with AN showed poorer ERA than the healthy control group (d = 0.71), particularly regarding emotions of negative valence (d = 0.26). Furthermore, a lower body weight (r = 0.41) and longer illness duration (ρ = -0.32) were associated with poorer ERA in the AN group. CONCLUSIONS: Using an ecologically valid instrument, the findings of the study support illness models emphasising poor ERA in AN. Directly addressing ERA in the treatment of AN with targeted interventions may be promising.

No effect of very brief exposure to masked food pictures on fear of food in anorexia nervosa.

OBJECTIVE: Very brief exposure to masked images of spider stimuli can facilitate approach behaviour towards spiders in fearful subjects. We hypothesized that a similar effect might occur for fear of food in patients with anorexia nervosa (AN), possibly offering a new treatment approach, with advantages over other methods of food exposure. METHODS: Patients with AN (n = 60) were randomly assigned to one of three experimental conditions and received a single session of exposure to either masked and very briefly presented food images, clearly visible food images, or masked non-food images (i.e. household items). Effects of the three exposure conditions on fear of food and food avoidance were examined. RESULTS: Contrary to our expectations, very brief food cue exposure was not superior to the control conditions regarding fear of food and approach behaviour towards food immediately after the intervention and body mass index four weeks later. CONCLUSION: This finding suggests important differences between fear of food in AN and specific phobias such as fear of spiders. The absence of an effect reveals limitations of the very brief exposure method, which might be better suited for evolutionarily relevant threat stimuli.

Improving emotion recognition in anorexia nervosa: An experimental proof-of-concept study.

OBJECTIVE: Previous research has found increasing evidence for difficulties in emotion recognition ability (ERA) and social cognition in anorexia nervosa (AN), and recent models consider these factors to contribute to the development and maintenance of the disorder. However, there is a lack of experimental studies testing this hypothesis. Therefore, the present proof-of-concept study examined whether ERA can be improved by a single session of a computerized training in AN, and whether this has short-term effects on eating disorder symptoms. METHOD: Forty inpatients (22.20 ± 7.15 years) with AN were randomly assigned to receive a single session of computerized training of ERA (TERA) or a sham training (training the recognition of different types of clouds). ERA, self-reported eating disorder symptoms, and body mass index (BMI) were assessed within 3 days before and after training. RESULTS: After training, both groups showed improved ERA, reduced self-reported eating disorder symptoms, and an increased BMI. As compared to patients in the control group, patients who received TERA showed greater improvements in ERA and self-reported eating disorder symptoms. DISCUSSION: ERA can be effectively trained in patients with AN. Moreover, short-term improvements in self-reported eating disorder symptoms provide tentative support for the hypothesis that difficulties in ERA contribute to the maintenance of AN, and that specific trainings of ERA hold promise as an additional component in AN treatment. Future studies are needed to replicate these findings in larger samples, and to investigate long-term effects and transfer into real-world settings.

Approach and avoidance bias for thin-ideal and normal-weight body shapes in anorexia nervosa.

OBJECTIVE: The two studies aimed to examine implicit affective evaluations of thin-ideal and normal-weight body shapes in women with anorexia nervosa (AN), taking identification with body shapes into account. METHOD: In study 1, approach-avoidance bias for thin-ideal and normal-weight bodies was assessed in 40 women with AN and 40 healthy women by using an Approach-Avoidance Task and female avatar bodies with a standard face as stimuli. In study 2, 39 women with AN and 38 healthy women underwent a similar task but identification with bodies was manipulated by presenting bodies once with the participant's own face and once with another woman's face. RESULTS: In study 1, patients with AN did not differ from healthy participants in their automatic approach-avoidance tendencies towards thin-ideal and normal-weight bodies. In study 2, no definite approach bias for a thin self and no avoidance bias for thin other women or for a normal-weight self were found. However, as compared to healthy women, those with AN showed a less positive implicit evaluation of thin other women, and an implicit preference for thin bodies depicted as themselves over thin bodies depicted as another woman. CONCLUSIONS: The findings suggest that intra-sexual competition for being slim is increased in AN.

[What do Patients Experience between Group Sessions during Inpatient Psychotherapy? An Application of the Inter-Session-Questionnaire in Psychotherapeutic Hospitals]. / Was erleben Patienten in stationärer Psychotherapie zwischen den Gruppentherapie-Sitzungen? Eine Erprobung des Inter-Session-Fragebogens in der Klinik.

The study describes an application of the Inter-Session-Questionnaire (ISF) related to inpatient group psychotherapy. The instrument should be tested with the extension of differentiating intersession experiences related to the person of the therapist as well as the group. In a cross sectional study performed in 13 different hospitals, 702 patients were assessed. These patients were treated in rehab hospitals, acute hospitals as well as special hospitals providing treatment for eating disorders. The sample should be relatively representative for psychosomatic and psychotherapeutic hospitals in Germany. Besides the type of the hospital, we also analysed the influence of group characteristics (size of group, type of group and number of completed sessions) as well as the patients' sex. Surprisingly, there were almost no marked differences of inter-session-experiences related to the the therapist or the group. The profiles of the item judgements of the ISF were similar to those reported for outpatient and day treatment samples. Inter-session-experiences differed in part according to our expectation depending on the variables mentioned above which suggests to use the ISF in specific studies dealing with the process and outcome of inpatient group psychotherapy as well as the differentiation of relevant subgroups.

Temperament and risk for exercise dependence: results of a pilot study in female patients with eating disorders compared to elite athletes.

BACKGROUND: The present pilot study investigated the relationship between temperament and the risk for exercise dependence (EXD). SAMPLING AND METHODS: A total of 32 female patients with eating disorders (potentially at risk for secondary EXD) and 29 female elite athletes without eating disturbances (potentially at risk for primary EXD) answered the Eating Disorder Examination-Questionnaire (EDE-Q), the Exercise Dependence Scale-German version (EDS-G), the Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) scales, and the effortful control subscale of the Adult Temperament Questionnaire (ATQ-EC). RESULTS: There were significant positive correlations of the EDS-G with the BIS in women with an eating disorder and with the BAS in elite athletes. No significant association was found between the EDS-G and effortful control. CONCLUSIONS: The results indicate that the risk for EXD is associated with avoidance tendencies in women with eating disorders and with approach tendencies in elite athletes. Implications for secondary and primary EXD are discussed.

[Training background, everyday practice, and training needs of group therapists working in inpatient psychotherapy - Results of a survey]. / Ausbildungshintergrund, Alltagspraxis und Weiterbildungsbedarf von Gruppenpsychotherapeuten in der stationären Psychotherapie - Ergebnisse einer Umfrage.

OBJECTIVES: A survey serves to clarify whether psychotherapists working in inpatient and day treatment psychotherapeutic hospitals feel sufficiently trained as group therapists and what their specific training needs are. METHODS: The survey queried 175 therapists from different hospitals and professions who perform group psychotherapy in their hospital. The questionnaire focussed on training experiences, everyday group practice, and training needs. RESULTS: As expected, only some of the therapists had completed training as group therapist. The therapists are faced with a wide variety of group formats and patients in their everyday work and reveal a broad spectrum of training needs. CONCLUSIONS: The survey, although not entirely representative, indicates general and specific needs of group therapists within psychotherapeutic hospitals and underlines the role of training and therapist experience in reducing uneasiness toward group psychotherapy.

Cognitive flexibility, central coherence, and quality of life in anorexia nervosa.

BACKGROUND: Anorexia nervosa (AN) has consistently been found to be associated with poor cognitive flexibility and central coherence. These two cognitive functions have been considered important maintenance factors in AN and are addressed by specific treatment approaches such as cognitive remediation therapy. While there is clear empirical evidence that difficulties in such cognitive functions are related to impaired daily functioning in schizophrenia and bipolar disorder, this potential association has received only little attention in AN research so far. Therefore, the aim of this study was to examine potential relationships between weak cognitive flexibility, central coherence, and poor quality of life (QoL) in AN. METHODS: Cognitive flexibility and central coherence were measured by both neuropsychological (i.e., performance based) and self-report measures alongside with self-reported QoL in a sample of 138 adult patients with AN. RESULTS: Self-report but not performance based measures of cognitive flexibility and central coherence were associated with QoL. Weaker cognitive flexibility and central coherence were correlated with poorer QoL. These associations were independent of comorbid depression. The link between weak central coherence and poor QoL was particularly strong in patients with the restricting subtype of AN. The link between cognitive flexibility and QoL, however, was independent of AN subtype. CONCLUSIONS: Weak cognitive flexibility and central coherence are associated with low QoL in AN, especially in patients with the restrictive subtype. However, this relationship is dependent on the method of measurement, where self-report measures seem to be more relevant than performance based measures.

Cognitive remediation therapy in anorexia nervosa-A randomized clinical trial.

Objective: Especially for adult patients with anorexia nervosa (AN), treatment response is generally low to moderate. The present study aimed to evaluate the efficacy of cognitive remediation therapy (CRT) as adjunctive treatment for AN regarding clinical and cognitive outcomes. Method: In this randomized controlled superiority trial, 167 adult and adolescent (≥17 years) patients with AN were randomly allocated (1:1) to 10 weekly sessions of group therapy of either CRT (n = 82) or art therapy (ART; n = 85) as an adjunct to inpatient treatment-as-usual (TAU). Outcomes were assessed at baseline, end-of-treatment (10 weeks), and 6-month follow-up. Change in body mass index (BMI), eating disorder psychopathology, and health-related quality of life (QoL) from baseline to 6-month follow-up served as primary outcomes. Improvements in motivation to change and several indices of set-shifting and central coherence between baseline and end-of-treatment and between baseline and 6-month follow-up served as secondary outcomes. Analysis was by intention to treat. Results: Treatment groups did not differ regarding change in BMI, eating disorder psychopathology, and health-related QoL from baseline to 6-month follow-up. Likewise, groups neither differed regarding improvements in these outcomes between baseline and end-of-treatment nor in motivation to change, set-shifting, and central coherence at any time, except for greater short-term improvements in one measure of set-shifting in the CRT group. Conclusions: CRT as an adjunct to inpatient TAU for AN was not efficacious in improving clinical and cognitive outcomes. The results do not support routine employment of CRT in inpatient treatment for AN. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Antimicrobial peptides in patients with anorexia nervosa: comparison with healthy controls and the impact of weight gain.

Clinical observations show that patients with anorexia nervosa (AN) are surprisingly free from infectious diseases. There is evidence from studies in Drosophila melanogaster that starvation leads to an increased expression of antimicrobial peptides (AMPs). AMPs are part of the innate immune system and protect human surfaces from colonization with pathogenic bacteria, viruses and fungi. We compared the expression of AMPs between patients with AN and healthy controls (HC) and investigated the influence of weight gain. Using a standardized skin rinsing method, quantitative determination of the AMPs psoriasin and RNase 7 was carried out by ELISA. Even though non-significant, effect sizes revealed slightly higher AMP concentrations in HC. After a mean weight gain of 2.0 body mass index points, the concentration of psoriasin on the forehead of patients with AN increased significantly. We could not confirm our hypotheses of higher AMP concentrations in patients with AN that decrease after weight gain. On the contrary, weight gain seems to be associated with increasing AMP concentrations.

Body image related negative interpretation bias in anorexia nervosa.

A distorted body image and pronounced body dissatisfaction are hallmarks of anorexia nervosa (AN) that typically result in dietary restraint and compensatory behaviours. Cognitive biases such as negative interpretation bias are considered key maintaining factors of these maladaptive cognitions and behaviours. However, little attention has been paid to empirical tests whether negative interpretation bias exists in AN and to what degree it is associated with symptom severity. Participants in the present study were 40 women with AN and 40 healthy women with no history of an eating disorder. Body-related negative interpretation bias (i.e., a tendency to interpret ambiguous information about the own body in a negative way) was measured by a Scrambled Sentences Task. Patients with AN showed a stronger body-related negative interpretation bias than healthy controls. Within both groups, negative interpretation bias correlated strongly and positively with AN symptom severity and these effects were not moderated by levels of depressive symptoms. The findings support the idea that biased interpretation of body-related information is associated with the specific psychopathology of AN. Targeted, computerised interventions (e.g. interpretation bias modification) may help to alter these dysfunctional cognitive schemas that lie at the heart of AN.

Does internet-based prevention reduce the risk of relapse for anorexia nervosa?

Technological advancements allow new approaches to psychotherapy via electronic media. The eating disorder literature currently contains no studies on internet intervention in anorexia nervosa (AN). This study presents a RCT on an internet-based relapse prevention program (RP) over nine months after inpatient treatment for AN. The sample comprised 258 women, randomized to the RP or treatment as usual (TAU). Expert- and self-ratings were evaluated by intent-to-treat analyses. Concerning age, age at onset and comorbidity, both groups were comparable at randomization. During the RP, the intervention group gained weight while the TAU group had minimal weight loss. RP completers gained significantly more body weight than patients in the TAU condition. Group-by-time comparisons for eating-related cognitions and behaviors and general psychopathology showed a significantly more favorable course in the RP program for "sexual anxieties" and "bulimic symptoms" (interview), and "maturity fears" and "social insecurity" (EDI-2). General psychopathology showed no significant group-by-time interaction. Important factors for successful relapse prevention were adherence to the intervention protocol and increased spontaneity. Considering the unfavorable course and chronicity of anorexia nervosa (AN), internet-based relapse prevention in AN following inpatient treatment appears a promising approach. Future internet-based programs may be further improved and enhanced.
