Mentalization-enhancing therapeutic interventions in the psychotherapy of anorexia nervosa: An analysis of use and influence on patients' mentalizing capacity.

OBJECTIVE: Improvement in patients' mentalizing capacities is considered a possible mechanism of change in psychotherapy. This improvement might take place via mentalization-enhancing interventions (MEIs) performed by psychotherapists. The study aimed to explore the use of MEIs in two evidence-based psychotherapeutic treatments for patients with anorexia nervosa (enhanced cognitive-behavior therapy, focal psychodynamic therapy) and their association with the patients' capacity to mentalize in sessions ("in-session reflective functioning" / in-session RF). Additionally, it was explored, if the amount of MEIs used could either predict change in in-session RF or outcome (end of treatment, one year follow-up). METHOD: 84 audiotapes from psychotherapy sessions of 28 patients of the ANTOP-study (three sessions per patient) were transcribed and rated with both the MEI Rating Scale and the In-Session RF Scale by trained raters. RESULTS: MEIs were applied in both treatments. A moderate correlation between the amount of MEIs and patients' in-session RF as well as its change over the course of treatment was found, but no relation to change in BMI or eating disorder symptoms. CONCLUSION: A greater use of MEIs was related to patients' in-session-mentalizing. However, there seems to be no simple relation between RF as shown in sessions and symptom change.

Reduced structural connectivity in the corpus callosum in patients with anorexia nervosa.

OBJECTIVE: Previous diffusion tensor imaging studies reported a reduced fractional anisotropy in the body of the corpus callosum in patients with anorexia nervosa, which may indicate impaired white matter integrity in interhemispheric connections. The aim of the current study was to investigate whether structural connectivity is affected in patients with anorexia nervosa. METHOD: To this end, we compared the number of streamlines (a model of the white matter fibre tracts) and the total volume filled by these streamlines in different subsections of the corpus callosum in 33 women with and 33 without anorexia nervosa as well as in 20 recovered individuals. RESULTS: The volume of streamlines in the anterior and mid-anterior subsection of the corpus callosum was reduced in women with, but not in those who had recovered from anorexia nervosa. No differences in number of streamlines was detected in the corpus callosum between patients with anorexia nervosa, healthy controls and recovered patients. CONCLUSIONS: Alterations of the corpus callosum have been repeatedly reported in anorexia nervosa. Since the recovered group did not differ from the healthy control group, the reported alterations in acute patients appear to represent a state and not a trait marker.

[Behavioral Addictions in Psychosomatic Care]. / Verhaltenssüchte in der psychosomatisch-psychotherapeutischen Versorgung.

OBJECTIVE: It is commonly agreed, that Behavioral Addictions are accompanied by mental disorders and are still underdiagnosed. The multicenter cross-sectional study aimed at estimating the prevalence of Behavioral Addictions in a consecutive sample of patients seeking treatment for mental disorders other than Behavioral Addiction. METHODS: The study included 801 patients from eight psychosomatic university hospitals. Behavioral Addictions were assessed via standardized questionnaires. RESULTS: 24.1% of the sample reported at least one Behavioral Addiction. The majority of those patients reported symptoms of a single Behavioral Addiction. Questionnaire-based prevalence rates were 3.4% for Pathological Gambling, 1.9% for Pathological Internet Use, 16.7% for Pathological Buying, 5.4% for Hypersexual Disorder, and 3.5% for pathological exercising (exercise dependence). Neither center nor setting (outpatient, inpatient, day clinic) effects were observable. DISCUSSION: Within this clinical sample, symptoms of shopping addiction are highly common in patients undergoing psychosomatic-psychotherapeutic treatment. These are rather women. Men are more likely to suffer from gambling and sex addiction. Generally, symptoms of Behavioral Addictions are commonly reported. Till today, Behavioral Addictions are often still underdiagnosed. CONCLUSION: Patients within psychosomatic treatment commonly suffer from symptoms of Behavioral Addictions, which should be considered for treatment strategies.

Implementation of mentalization-based treatment in a day hospital program for eating disorders-A pilot study.

OBJECTIVE: Aim of the pilot study was to evaluate the effectiveness of a day hospital program for eating disorders (EDs) after implementation of mentalization-based treatment (MBT), including a comparison to a historical matched control group. METHOD: All consecutively admitted patients with an ED were included in a prospective, observational study over a period of 2 years. Main outcome criteria were eating and overall psychopathology. Furthermore, changes in the capacity to mentalize (reflective functioning [RF]), difficulties with affect regulation and interpersonal problems were assessed at admission, discharge and a three months follow-up. RESULTS: Thirty-eight out of fourty patients could be included. The program led to significant reductions in eating and general pathology. There was significant improvement in RF, difficulties in emotion regulation and interpersonal functioning. However, there was no advantage in comparison to a matched control group (main outcomes). ED symptoms showed a slight renewed increase after discharge, while body mass index further increased. RF change was predictive of change in overall psychopathology, but not ED symptoms. Drop-out rate was 13.2%. CONCLUSION: The program showed no advantage in comparison to a historical control group concerning a reduction in eating and overall psychopathology. However, it was associated with low drop-out rates, and changes which MBT targets: An increase in RF and a reduction of interpersonal problems as well as difficulties in emotion regulation.

Psychological and nutritional correlates of objectively assessed physical activity in patients with anorexia nervosa.

BACKGROUND: Physical activity (PA) plays a role in the course of anorexia nervosa (AN). OBJECTIVE: To assess the association between PA, nutritional status and psychological parameters in patients with AN. METHOD: Using a wearable activity monitor, PA was assessed in 60 female AN inpatients, by step count and time spent in 4 metabolic equivalent (MET)-intensity levels: sedentary behaviour, light, moderate and vigorous PA. In addition, BMI, psychological (patient-reported outcome questionnaires) and nutritional parameters (body fat, energy and macronutrient intake) were assessed. RESULTS: The study population spent little time in vigorous PA. BMI on admission and discharge was higher when more time was spent in sedentary behaviour, and lower with more time spent in light PA. Relationships between PA and patient-reported outcomes were weak and limited to an association between vigorous PA and compulsiveness. Low fat mass was associated with more time spent in light PA, while subjects with higher step counts showed less intake of energy, carbohydrates and fat. CONCLUSION: The relationship between inadequate food intake and increased PA in patients with AN requires further investigation.

[Therapeutic Effort in Inpatient or Day Patient Treatments and Therapy Success in Patients with Depressive Disorders]. / Therapeutischer Aufwand in stationärer oder tagesklinischer Behandlung und Therapieerfolg bei Patienten mit depressiven Störungen.

Several therapeutic treatments like individual psychotherapy, group therapy, creative therapies and talks with the nursing staff are components in an inpatient psychosomatic (psychotherapeutic) treatment or a psychosomatic day hospital treatment. In Germany, these therapies have to be documented by the administration with so called OPS-Codes. These codes are reported to the Institute for Reimbursement in Hospitals (InEK). With the data of the INDDEP-study it should be investigated how the therapies of 7 hospitals and 8 day-hospitals compare to each other. In addition, it should be studied, if the amount of the documented therapies is connected to the outcome in these hospitals. In the INDDEP-study, data of patients with major depression were assessed at 4 measurement points (admission, discharge, 3 months and 12 months follow up). In addition, the OPS codes of the treatments were documented. The results show that it is possible to get a rough estimation of the psychotherapeutic doses by the OPS-codes. The results show significant differences between the hospitals in terms of the intensity and professional group composition of the treatments. This result is confirmed for in-patient and day hospital treatments. Correlation analyses showed no significant correlation between the total amount of therapy and the improvement in depressive symptoms. It is assumed that there are moderating variables (patient-, therapy and process-related) which moderate the relation between doses and outcome. This should be identified in further studies.

Altered cortical folding and reduced sulcal depth in adults with anorexia nervosa.

OBJECTIVE: Previous studies on anorexia nervosa (AN) focused on cortical volume and mainly reported grey matter reduction. They also investigated cortical surface parameters, for example, absolute mean curvature (AMC) providing information on cortical folding or sulcal depth (SD). For the first time, we also analysed cortical complexity using fractal dimension (FD) in AN. METHOD: In a cross-sectional study, we performed surface analyses (AMC, SD, and FD) on 34 women with AN, 24 recovered from AN (REC), and 41 healthy controls (HC). Structural MR data was processed using the Computational Anatomy Toolbox and statistically compared across groups on a vertex- and region-of-interest-wise level using statistical parametric mapping. RESULTS: We found a lower AMC and SD in AN, especially in temporal areas. FD was increased in the left precentral gyrus in AN. No differences of the parameters AMC, SD, or FD were evident between REC and HC participants. CONCLUSIONS: Alterations in AMC, SD, and FD in AN patients, but not between the REC and HC groups, suggest that these alterations are state related. The findings concur with other structural AN studies that suggest restitution with clinical recovery. The changes may be due to malnutrition, dehydration, osmotic dysregulation, or hormonal aberrations during the acute stage.

Neurobiological signature of intimacy in anorexia nervosa.

BACKGROUND: Intimacy and psychosexual development represent core problems of anorexia nervosa (AN). Experiential and neurobiological evidence however is scarce. MATERIAL AND METHODS: Thirty-one female AN patients were compared with 35 non-patients (NP) and 22 recovered participants (REC) by using functional magnetic resonance imaging. Participants viewed pictures of couples in intimate relationships and control stimuli. RESULTS: AN patients experienced intimate stimuli with lower valence and dominance. AN showed decreased activation of parietal cortices. NP decreased the prefrontal cortex response, which AN patients did not. REC participants did not differ from NP on a behavioural level, though with regard to the neural signature. DISCUSSION: Parietal cortices are related to processing of erotic themes, which seems to be deficient in AN. Dysfunction of prefrontal cortices likely mirrors dysfunctional control in AN. The neural signature does not seem to be state-related considering results of REC.

The importance of body image disturbances for the outcome of outpatient psychotherapy in patients with anorexia nervosa: Results of the ANTOP-study.

This study investigates the role of body image self-appraisal in predicting the outcomes of outpatient psychotherapy in patients with anorexia nervosa (AN). Multiple linear regression analyses and a path-analysis model were applied to test the study hypotheses that body image at baseline predicts treatment outcomes of outpatient psychotherapy in patients with AN at follow-up measurement. The analyses were conducted as secondary analyses in a subgroup (n = 148) of the anorexia nervosa treatment of outpatient-cohort (ANTOP-study) (N = 242) of patients with AN. The results show that Negative Evaluation of the Body at baseline predicts perceived stress during psychotherapy, which in turn predicts depressive symptoms at the end of therapy which in turn predicts the outcomes body mass index and EDI-2 sum score at 12 months follow-up. The results underline the importance of body image disturbance in the course of AN and call for body image as a central target of psychotherapeutic interventions in patients with AN.

Reasons for non-response and recommendations for optimal outpatient treatment of bulimia nervosa: A survey on German expert therapists' views.

Objectives: Remission rates after treatment for bulimia nervosa can be considered insufficient. The study aimed to explore the perspective of expert psychotherapists on possible reasons for non-response and recommendations for an optimized treatment. Methods: Experts filled in a questionnaire that comprised questions about possible reasons for low remission rates as well as ratings of interventions suggested for different treatment phases and subgroups of patients. Results: 56 experienced therapists could be included in the survey. Ambivalence of patients, insufficient training of therapists and heterogeneity of the patient group were most often rated as possible reasons for insufficient outcomes. For optimized treatment, therapists recommended a combination of cognitive-behavioral and psychodynamic techniques, depending on treatment phase and patient characteristics. Conclusions: Further research should examine, if a more specific training of therapists, a more integrative approach and flexible adaptations of interventions to patients' characteristics are effective strategies to improve outcome.

Recovery of cortical volume and thickness after remission from acute anorexia nervosa.

OBJECTIVE: Reduced grey (GM) and white matter (WM) volumes and increased cerebrospinal fluid (CSF) have been frequently reported in anorexia nervosa (AN), but studies focusing on cortical thickness (CT) are scarce and findings inconsistent. We conducted the first study in AN that analyzed both parameters in the same study to gain novel and comprehensive insight. METHOD: Voxel-based morphometry (VBM) analysis was performed on T1-weighted magnetic resonance images from 34 predominantly adult women with acute AN, 24 REC participants, and 41 healthy controls (HC). Global brain segment volumes (GM, WM, and CSF), regional GM volume, and cortical thickness measures were obtained from the same study sample. We further focused on recovery by including a REC group. RESULTS: The GM and WM volumes were decreased, and correspondingly, the CSF volume increased in the AN in comparison to the HC and REC groups. No significant volume differences between the REC and HC groups could be observed. AN patients showed reduced regional GM volumes in the right hippocampus and the left middle and right inferior frontal gyrus. Cortical thinning occurred in the AN group, which was particularly robust in fronto-parietal areas. The REC and HC groups failed to show any regional GM or cortical thickness differences. DISCUSSION: AN is accompanied by severe loss of brain volume and cortical thickness as assessed by complementary investigation tools. However, these changes seem to be largely reversible, which should be encouraging for therapists and patients. The underlying neurobiological mechanisms remain unclear and should be assessed in further studies.

Validation of the German Version of the Commitment to Exercise Scale.

Pathological forms of exercising are a topic of debate in terms of classification, etiology, and treatment. Validated instruments are a precondition for research in this field. The aim of this study was to validate the German version of the Commitment to Exercise Scale (CES-de). A confirmatory factor analysis was conducted using data from a large community sample (n = 571). In a second study, 100 eating disordered patients, 107 elite athletes and 100 individuals engaged in leisure time sporting activities were compared to assess discriminant validity and psychological correlates. A 1-factor solution showed the best fit to the data. The CES-de differentiated between the eating disordered group and individuals engaged in leisure time sporting activities, but not between those with an eating disorder and competitive athletes. The total score was significantly correlated with drive for thinness, perfectionism, and overall psychopathology. The CES-de can be considered a valid instrument for measuring problematic behavioral and attitudinal aspects of the commitment to exercise. The use of the CES-de total score is recommended. However, a more specific instrument should be used for athletes. A limitation of the study is that the samples were not stratified by age and gender.

Decreased Emotional Perception in Obesity.

BACKGROUND: There is hardly any empirical evidence on emotion processing by controlled studies in obesity. MATERIAL AND METHODS: Participants rated their emotions in response to visual emotional stimuli from the International Affective Picture System. Study 1 compared obese women with normal-weight controls and women with eating disorders. Study 2 compared obese men with normal-weight controls. RESULTS: Obese women had reduced emotional intensity scores for all basic emotions and the mixed emotion sadness-fear. Obese men had reduced scores for all emotions except happiness and disgust; anger showed a trend towards significance. The results were mainly based on ratings from non-depressed obese individuals. DISCUSSION: Obese men and women scored significantly lower on most basic and mixed emotions. Non-depressed obese subjects seem particularly affected. These new findings must be validated by further study, and longitudinal evaluation after weight loss, e.g. by bariatric surgery, will be of interest.

The Intersession Process in Psychotherapy for Anorexia Nervosa: Characteristics and Relation to Outcome.

OBJECTIVE: The "inter session process" (ISP) is defined as therapy-related conscious thoughts, memories, and emotions that patients and therapists experience between psychotherapy sessions. It indicates how the participants process and use treatment. The main aim of this study is to describe the ISP characteristics of patients in outpatient treatment for anorexia nervosa (AN). An additional aim is to explore the relation between patients' ISP and treatment outcome. METHOD: Patients taking part in a randomized controlled trial on outpatient psychotherapy for AN (ANTOP) filled in the Intersession Experience Questionnaire before each of the 40 psychotherapy sessions. Trajectories of different aspects of the ISP were analyzed with growth curve models based on orthogonal polynomials and tested for differences between 3 outcome categories (recovery, partially recovered, full syndrome AN). RESULTS: Data from 108 cases were available for analysis. ISP facets showed diverse, mostly nonlinear, trajectories over the course of treatment. Less favorable outcomes were associated with higher levels of patients' experiencing negative emotions when recalling therapeutic dialogue, thinking about therapy during dreaming/drowsy states, and applying therapeutic learning (in the second half of treatment). CONCLUSIONS: Findings confirm an overall relation between ISP and treatment outcome. In outpatient treatment in AN, patients with a less successful course seem to be more preoccupied with therapy and therapist between sessions. For the ISP facet "applying therapeutic learning," findings point to an optimal range dependent on treatment phase. Growth curve modeling is required to describe the nonlinear trajectories of ISP facets.

Focal psychodynamic therapy, cognitive behaviour therapy, and optimised treatment as usual in outpatients with anorexia nervosa (ANTOP study): randomised controlled trial.

BACKGROUND: Psychotherapy is the treatment of choice for patients with anorexia nervosa, although evidence of efficacy is weak. The Anorexia Nervosa Treatment of OutPatients (ANTOP) study aimed to assess the efficacy and safety of two manual-based outpatient treatments for anorexia nervosa--focal psychodynamic therapy and enhanced cognitive behaviour therapy--versus optimised treatment as usual. METHODS: The ANTOP study is a multicentre, randomised controlled efficacy trial in adults with anorexia nervosa. We recruited patients from ten university hospitals in Germany. Participants were randomly allocated to 10 months of treatment with either focal psychodynamic therapy, enhanced cognitive behaviour therapy, or optimised treatment as usual (including outpatient psychotherapy and structured care from a family doctor). The primary outcome was weight gain, measured as increased body-mass index (BMI) at the end of treatment. A key secondary outcome was rate of recovery (based on a combination of weight gain and eating disorder-specific psychopathology). Analysis was by intention to treat. This trial is registered at http://isrctn.org, number ISRCTN72809357. FINDINGS: Of 727 adults screened for inclusion, 242 underwent randomisation: 80 to focal psychodynamic therapy, 80 to enhanced cognitive behaviour therapy, and 82 to optimised treatment as usual. At the end of treatment, 54 patients (22%) were lost to follow-up, and at 12-month follow-up a total of 73 (30%) had dropped out. At the end of treatment, BMI had increased in all study groups (focal psychodynamic therapy 0·73 kg/m(2), enhanced cognitive behaviour therapy 0·93 kg/m(2), optimised treatment as usual 0·69 kg/m(2)); no differences were noted between groups (mean difference between focal psychodynamic therapy and enhanced cognitive behaviour therapy -0·45, 95% CI -0·96 to 0·07; focal psychodynamic therapy vs optimised treatment as usual -0·14, -0·68 to 0·39; enhanced cognitive behaviour therapy vs optimised treatment as usual -0·30, -0·22 to 0·83). At 12-month follow-up, the mean gain in BMI had risen further (1·64 kg/m(2), 1·30 kg/m(2), and 1·22 kg/m(2), respectively), but no differences between groups were recorded (0·10, -0·56 to 0·76; 0·25, -0·45 to 0·95; 0·15, -0·54 to 0·83, respectively). No serious adverse events attributable to weight loss or trial participation were recorded. INTERPRETATION: Optimised treatment as usual, combining psychotherapy and structured care from a family doctor, should be regarded as solid baseline treatment for adult outpatients with anorexia nervosa. Focal psychodynamic therapy proved advantageous in terms of recovery at 12-month follow-up, and enhanced cognitive behaviour therapy was more effective with respect to speed of weight gain and improvements in eating disorder psychopathology. Long-term outcome data will be helpful to further adapt and improve these novel manual-based treatment approaches.

Immediate Effects of Body Checking Behaviour on Negative and Positive Emotions in Women with Eating Disorders: An Ecological Momentary Assessment Approach.

OBJECTIVES: Cognitive-behavioural models of eating disorders state that body checking arises in response to negative emotions in order to reduce the aversive emotional state and is therefore negatively reinforced. This study empirically tests this assumption. METHODS: For a seven-day period, women with eating disorders (n = 26) and healthy controls (n = 29) were provided with a handheld computer for assessing occurring body checking strategies as well as negative and positive emotions. Serving as control condition, randomized computer-emitted acoustic signals prompted reports on body checking and emotions. RESULTS: There was no difference in the intensity of negative emotions before body checking and in control situations across groups. However, from pre- to post-body checking, an increase in negative emotions was found. This effect was more pronounced in women with eating disorders compared with healthy controls. DISCUSSION: Results are contradictory to the assumptions of the cognitive-behavioural model, as body checking does not seem to reduce negative emotions.

The Freiburg sport therapy program for eating disordered outpatients: a pilot study.

PURPOSE: Many patients with anorexia or bulimia nervosa use physical activity as a method to influence weight and shape and/or exercise in a compulsive manner. This form of exercising is associated with a more severe illness and higher relapse rates. In a proof-of-concept study, effects of a newly developed sport therapy program aiming to reduce unhealthy exercising were assessed. METHODS: Thirty-six patients with eating disorders took part in four group terms of the program, each lasting 3 months. They were compared to a matched control group. Main outcome criterion was a reduction in the total score of the commitment to exercise scale (CES). RESULTS: In the completer analysis, we found statistically significant reductions in the CES total score over time (time × group; p = 0.003) and significant improvements in overall eating psychopathology and quality of life (pre â†’ post). The dropout rate was high (34 %), mainly due to external reasons (time schedule, etc.). CONCLUSIONS: Findings point to specific effects of a newly developed outpatient sport therapy program for eating disorders. Detailed assessments of patients before assigning them to the program will be necessary to reduce dropout rates. The next step has to be a randomized controlled study.

Accuracy of therapist perceptions of patients' alliance: Exploring the divergence.

OBJECTIVE: The therapeutic alliance is a well-established predictor of psychotherapy outcome, yet much research has shown that therapists' and patients' views of the alliance can diverge substantially. Therapists systematically underestimate their patients' perceived level of alliance, and the correlation between therapist and patient estimates of patient alliance is only moderate. The present study explored the divergence between therapists' and patients' perspectives on patients' alliance experience, and its relations to therapists' concurrent work involvement and session process experiences. METHOD: Data from 98 patients treated by 26 therapists with psychodynamic psychotherapy were analyzed. RESULTS: Therapist-patient divergence was significantly related to therapists' case-wise work involvement, but not to therapist's views of session process. The best predictor of therapist-patient divergence was therapists experiencing a "distressed practice" work involvement pattern. CONCLUSION: Although therapists' work involvement experiences are not commonly investigated, they can be a relevant predictor of therapy processes.
