Mentalizing in psychotherapeutic processes of patients with eating disorders

Background

Improvement in the capacity to mentalize (i.e., reflective functioning/RF) is considered both, an outcome variable as well as a possible change mechanism in psychotherapy. We explored variables related to (in-session) RF in patients with an eating disorder (ED) treated in a pilot study on a Mentalization-Based Treatment (MBT) - oriented day hospital program. The research questions were secondary and focused on the psychotherapeutic process: What average RF does the group of patients show in sessions and does it change over the course of a single session? Are differences found between sections in which ED symptomatology is discussed and those in which it is not? Does RF increase after MBT-type interventions?

Methods

1232 interaction segments from 77 therapy sessions of 19 patients with EDs were rated for RF by reliable raters using the In-Session RF Scale. Additionally, content (ED symptomatology yes/no) and certain MBT interventions were coded. Statistical analysis was performed by mixed models.

Results

Patients showed a rather low RF, which increased on average over the course of a session. If ED symptomatology was discussed, this was associated with significantly lower RF, while MBT-type interventions led to a significant increase in RF.

Conclusions

Results suggest that in-session mentalizing can be stimulated by MBT-typical interventions. RF seems to be more impaired when disorder-specific issues are addressed. Further studies have to show if improving a patient´s ability to mentalize their own symptoms is related to better outcomes.

Words count in psychotherapy: Differentiating language characteristics of cognitive behavioral therapy and focal psychodynamic therapy for anorexia nervosa

It is generally assumed that psychodynamic therapy and cognitive behavioral therapy (CBT) differ in terms of applied techniques and processes. To date, however, little is known about whether and how such differences can actually be observed at a basic linguistic level and in what the two treatment approaches differ most strongly (i.e., how psychodynamic and CBT therapists differ in what they actually say word-by-word in therapy sessions). Building on theoretical models and previous research that used observer ratings, we formulated specific hypotheses regarding which word categories psychodynamic and CBT therapists who treat patients with an eating disorder should differ in. To investigate these hypotheses, we used verbatim transcripts from 297 therapy sessions of a randomized controlled trial in which patients with anorexia nervosa (n = 88) received either focal psychodynamic therapy (FPT) or CBT. These transcripts were then examined using computerized quantitative text analysis. In line with our hypotheses, we found that CBT therapists overall spoke more than their FPT counterparts and that they used more words related to eating. Also in line with our hypotheses, FPT therapists used more words related to social processes. Contrary to our expectations, CBT therapists did not show a stronger focus on the future but talked more about emotions than FPT therapists. The latter effect, however, appears to be driven by a stronger focus on positive emotions. These findings suggest that computerized quantitative text analysis can differentiate meaningful language characteristics of CBT and FPT on spoken-word level and that it holds potential as a tool for researchers and therapists.

The role of general change mechanisms in sudden gains in the treatment of anorexia nervosa

Previous research has shown a robust association between sudden gains (SGs) and treatment outcome in psychotherapy for various mental disorders including anorexia nervosa (AN). However, little is known about factors contributing to SGs. This study investigated the role of general change mechanisms in body-weight related SGs in AN. Data were drawn from a randomized-controlled trial on cognitive-behavioral therapy (CBT) and focal psychodynamic therapy (FPT) for adult outpatients with AN. Session-level data on the general change mechanisms 'clarification' (insight), 'mastery' (coping), and 'therapeutic relationship' were analyzed. Pre-gain sessions were compared with control (pre-pre-gain) sessions in 99 patients with a SG in body weight. Additionally, propensity score matching was used to compare data from pre-gain sessions from 44 patients with SG and data from the corresponding session from 44 patients without SG. In the pre-gain session, patients experienced higher levels of clarification and mastery but not therapeutic relationship. Compared to patients without a SG, patients with a SG likewise experienced more clarification and mastery but not a better therapeutic relationship in the pre-gain/corresponding session. CBT and FPT did not differ regarding these effects. The findings suggest that general change mechanisms contribute to SGs in CBT and FPT for AN.

Typical disease courses of patients with unipolar depressive disorder after in-patient treatments-results of a cluster analysis of the INDDEP project

Introduction

Previously established categories for the classification of disease courses of unipolar depressive disorder (relapse, remission, recovery, recurrence) are helpful, but insufficient in describing the naturalistic disease courses over time. The intention of the present study was to identify frequent disease courses of depression by means of a cluster analysis.

Methods

For the longitudinal cluster analysis, 555 datasets of patients who participated in the INDDEP (INpatient and Day clinic treatment of DEPression) study, were used. The present study uses data of patients with at least moderate depressive symptoms (major depression) over a follow-up period of 1 year after their in-patient or day-care treatments using the LIFE (Longitudinal Interval Follow-Up Evaluation)-interview. Eight German psychosomatic hospitals participated in this naturalistic observational study.

Results

Considering only the Calinski-Harabatz index, a 2-cluster solution gives the best statistical results. In combination with other indices and clinical interpretations, the 5-cluster solution seems to be the most interesting. The cluster sizes are large enough and numerically balanced. The KML-cluster analyses revealed five well interpretable disease course clusters over the follow-up period: "sustained treatment response" (N = 202, 36.4% of the patients), "recurrence" (N = 80, 14.4%), "persisting relapse" (N = 115, 20.7%), "temporary relapse" (N = 95, 17.1%), and remission (N = 63, 11.4%).

Conclusion

The disease courses of many patients diagnosed with a unipolar depression do not match with the historically developed categories such as relapse, remission, and recovery. Given this context, the introduction of disease course trajectories seems helpful. These findings may promote the implementation of new therapy options, adapted to the disease courses.

State or trait: the neurobiology of anorexia nervosa - contributions of a functional magnetic resonance imaging study

BACKGROUND

The understanding of the cerebral neurobiology of anorexia nervosa (AN) with respect to state- versus trait-related abnormalities is limited. There is evidence of restitution of structural brain alterations with clinical remission. However, with regard to functional brain abnormalities, this issue has not yet been clarified.

METHODS

We compared women with AN (n = 31), well-recovered female participants (REC) (n = 18) and non-patients (NP) (n = 27) cross-sectionally. Functional magnetic resonance imaging was performed to compare neural responses to food versus non-food images. Additionally, affective ratings were assessed.

RESULTS

Functional responses and affective ratings did not differ between REC and NP, even when applying lenient thresholds for the comparison of neural responses. Comparing REC and AN, the latter showed lower valence and higher arousal ratings for food stimuli, and neural responses differed with lenient thresholds in an occipital region.

CONCLUSIONS

The data are in line with some previous findings and suggest restitution of cerebral function with clinical recovery. Furthermore, affective ratings did not differ from NP. These results need to be verified in intra-individual longitudinal studies.

Focal psychodynamic therapy, cognitive behaviour therapy, and optimised treatment as usual in female outpatients with anorexia nervosa (ANTOP study): 5-year follow-up of a randomised controlled trial in Germany

BACKGROUND

Anorexia nervosa is a serious illness leading to substantial morbidity and mortality. The Anorexia Nervosa Treatment of Outpatients (ANTOP) study is the largest randomised controlled trial (RCT) globally that uses psychotherapy in outpatients with anorexia nervosa. In this Article, we report the results of the 5-year follow-up.

METHODS

The ANTOP study is an open-label, multicentre RCT involving 242 adult female outpatients with anorexia nervosa. Participants were recruited from ten university hospitals in Germany, had to be aged at least 18 years and female, and have a diagnosis of anorexia nervosa with a body-mass index (BMI) of 15·0-18·5 kg/m². Participants were randomly allocated (1:1:1) to 10 months of treatment with focal psychodynamic therapy, enhanced cognitive behaviour therapy, or optimised treatment as usual; complete masking of the participants was not possible. The mean duration of the follow-up was 5·96 years (SD 0·2) after randomisation. The primary outcome was change in BMI from baseline at the end of treatment; here, we present the change in BMI from baseline to the 5-year follow-up, using an intention-to-treat approach with a mixed model for repeated measurements. Groups were also compared according to global outcome (based on the combination of BMI and measures of anorexia severity), eating pathology (based on the Eating Disorder Inventory 2), and other secondary mental health outcomes. We did a linear regression analysis to identify the predictors of BMI at follow-up.

FINDINGS

Between May, 2007, and June, 2009, we screened 727 patients for eligibility; at baseline, 242 patients with a mean BMI of 16·7 kg/m² (SD 1·0) were included and randomly allocated to 10 months of treatment with focal psychodynamic therapy, enhanced cognitive behaviour therapy, or optimised treatment as usual. 154 (64%) of 242 patients completed the 5-year follow-up assessment (53 [66%] of 80 in the focal psychodynamic therapy group, 55 [69%] of 80 in the enhanced cognitive behaviour therapy group, and 46 [56%] of 82 in the optimised treatment-as-usual group), with a mean age of 32·4 years; all reported their ethnicity as White. At the 5-year follow-up, there was an improvement in mean BMI, eating pathology, and global outcome in all treatment groups with no significant differences between treatment groups. Estimated mean BMI was: 18·64 kg/m² (95% CI 18·07-19·21) in the focal psychodynamic therapy group (with an estimated mean BMI gain from baseline to 5-year follow-up of 1·91 kg/m² [1·34-2·48]); 18·70 kg/m² (18·15-19·25) in the enhanced cognitive behaviour therapy group (with an estimated mean BMI gain of 1·98 kg/m² [1·43-2·53]); and 18·99 kg/m² (18·39-19·59) in the optimised treatment-as-usual group (with an estimated mean BMI gain of 2·26 kg/m² [1·67-2·86]). There were no significant differences between treatment groups regarding BMI at the 5-year follow-up; the estimated difference was -0·06 (-0·85 to 0·73) between the focal psychodynamic therapy and enhanced cognitive behaviour therapy groups; -0·35 (-1·18 to 0·47) between the focal psychodynamic therapy and optimised treatment-as-usual groups; and -0·29 (-1·10 to 0·52) between the enhanced cognitive behaviour therapy and optimised treatment-as-usual groups. On the basis of observed data, global outcome at the 5-year follow-up showed 41% (33-49) full recoveries, 41% (33-49) partial recoveries, and 18% (12-24) with full-syndrome anorexia nervosa. One patient initially treated in the enhanced cognitive behaviour therapy group died by suicide between the 1-year and 5-year follow-up. BMI at the 5-year follow-up was predicted by BMI at baseline (p=0·0021), illness duration (p=0·0004), and depression at baseline (p=0·012).

INTERPRETATION

The long-term results of the ANTOP trial confirm the improvement in BMI of patients with anorexia nervosa in all groups; however, a substantial proportion of patients had a poor global outcome. The predictors for the long-term course of anorexia nervosa in our ANTOP study show that we need to treat patients with anorexia nervosa at an earlier stage of the disease, with a clear focus on weight gain and considering other comorbidities (especially depression).

Relationship between dental experiences, oral hygiene education and self-reported oral hygiene behaviour

Many preventive approaches in dentistry aim to improve oral health through behavioural instruction or intervention concerning oral health behaviour. However, it is still unknown which factors have the highest impact on oral health behaviours, such as toothbrushing or regular dental check-ups. Various external and internal individual factors such as education, experience with dentists or influence by parents could be relevant. Therefore, the present observational study investigated the influence of these factors on self-reported oral heath behaviour. One hundred and seventy participants completed standardized questionnaires about dental anxiety (Dental Anxiety Scale (DAS), and dental self-efficacy perceptions (dSEP)). They also answered newly composed questionnaires on oral hygiene behaviours and attitudes, current and childhood dental experiences as well as parental oral hygiene education and care. Four independent factors, namely attitude towards oral hygiene, attitude towards one's teeth, sense of care and self-inspection of one's teeth were extracted from these questionnaires by rotating factor analysis. The results of the questionnaires were correlated by means of linear regressions. Dental anxiety was related to current negative emotions when visiting a dentist and negative dental-related experiences during childhood. High DAS scores, infantile and current negative experiences showed significant negative correlations with the attitude towards oral hygiene and one's teeth. Dental anxiety and current negative dental experiences reduced participants' dental self-efficacy perceptions as well as the self-inspection of one's teeth. While parental care positively influenced the attitude towards one's teeth, dental self-efficacy perceptions significantly correlated with attitude towards oral hygiene, self-inspection of one's teeth and parental care. Dental anxiety, dental experiences, parents' care for their children's oral hygiene and dental self-efficacy perceptions influence the attitude towards oral hygiene and one's own oral cavity as well as the autonomous control of one's own dental health. Therefore, oral hygiene instruction and the development of patient-centred preventive approaches should consider these factors.

In-Session-Reflective-Functioning in Anorexia Nervosa: An Analysis of Psychotherapeutic Sessions of the ANTOP Study

OBJECTIVE

Previous research suggests that patients with anorexia nervosa (AN) show an impaired capacity to mentalize (reflective functioning, RF). RF is discussed as a possible predictor of outcome in psychotherapeutic processes. The study aimed to explore RF in sessions of patients with AN and its association with outcome and type of treatment.

METHODS

A post-hoc data analysis of selected cases from a randomized trial on outpatient psychotherapy for AN was conducted. Transcripts from 84 sessions of 28 patients (early phase, middle phase, and end of treatment) were assessed using the In-Session-Reflective-Functioning-Scale [14 cognitive-behavior therapy, enhanced (CBT-E); 14 focal psychodynamic therapy (FPT); 16 with good, 12 with poor outcome after 1 year]. Relations between the level of RF, type of treatment, and outcome were investigated using mixed linear models. Additionally, associations with depressive symptoms, weight gain, and therapeutic alliance were explored.

RESULTS

Mean in-session RF was low. It was higher in FPT when compared to CBT-E treatments. The findings point to an association between RF increase and a positive outcome. An increase in BMI in the first half of treatment was associated with higher subsequent in-session RF. There was no association between RF and depressive symptoms or the therapeutic alliance.

DISCUSSION

Patients with AN show a low capacity to mentalize in sessions, which seems to be at least partly dependent on the degree of starvation. The results suggest a possible relationship between an increase in in-session RF and outcome, which has to be replicated by further studies.

[Behavioral Addictions in Psychosomatic Care]

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.

Efficacy of post-inpatient aftercare treatments for anorexia nervosa: a systematic review of randomized controlled trials

BACKGROUND

Early relapse after inpatient treatment is a serious problem in the management of anorexia nervosa (AN). Specialized aftercare interventions have the potential to bridge the gap between inpatient and outpatient care, to prevent relapse and to improve the long-term outcome for patients with AN.

METHODS

Following the guidelines of the PRISMA statement, we conducted a systematic review, synthesizing the evidence from randomized-controlled trials (RCTs) investigating the efficacy of post-inpatient aftercare treatments for AN.

RESULTS

Our search resulted in seven RCTs and three registered ongoing trials. Pharmacotherapy and low-threshold guided self-help have limited uptake and high dropout. Novel mobile guided self-help approaches seem promising due to high patient satisfaction, but their efficacy has yet to be investigated in larger trials. Cognitive-behavior psychotherapy may be beneficial in delaying relapse, but evidence is based on a single study.

CONCLUSION

Only a limited number of RCTs investigating aftercare interventions for patients with AN is available. There is no clear evidence favoring any one specific approach for post-inpatient aftercare in adult patients with AN. The field faces many challenges which generally affect intervention research in AN. A specific issue is how to increase uptake of and reduce dropout from aftercare interventions. This calls for better tailoring of interventions to patient needs and the integration of patient perspectives into treatment. Intensified research and care efforts are needed to address the problem of recurrent relapse after intensive inpatient treatment for AN and to eventually improve prognosis for this eating disorder.

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.

Specialized post-inpatient psychotherapy for sustained recovery in anorexia nervosa via videoconference - study protocol of the randomized controlled SUSTAIN trial

BACKGROUND

A major barrier to long-term recovery from anorexia nervosa (AN) are early and frequent relapses after inpatient treatment. There is an urgent need for enhanced continuity of specialized care involving effective aftercare interventions and relapse prevention strategies in order to improve the long-term outcome for patients with AN.

METHODS

SUSTAIN is a multi-center, prospective, randomized-controlled trial investigating the efficacy of a novel post-inpatient aftercare intervention for patients with AN as compared to optimized treatment-as-usual (TAU-O). The SUSTAIN aftercare intervention is based on the cognitive-interpersonal maintenance model of AN and specifically tailored to achieve sustained recovery in AN following inpatient treatment. The SUSTAIN aftercare intervention comprises 20 treatment sessions over eight months and will be predominantly delivered via videoconference to overcome discontinuity of care. TAU-O refers to routine outpatient psychotherapy as generally offered in the German health care system. A total number of 190 patients receiving inpatient or day-hospital treatment for AN will be randomized and assessed over a 14-month period following randomization including a 6 months follow-up. Minimum Body Mass Index (BMI) is 15 kg/m² at trial inclusion. The primary efficacy endpoint is the change in BMI between baseline (T0) and end of treatment (T2) adjusted for baseline BMI. Key secondary outcomes comprise eating disorder and general psychopathology, quality of life, proportion of relapse and of weight restoration, and cost-effectiveness.

DISCUSSION

The results of the present trial will provide evidence if the novel aftercare intervention fosters sustained recovery in patients affected by severe courses of AN.

TRIAL REGISTRATION

The SUSTAIN trial was prospectively registered on November 18, 2020, under the registration number DRKS00023372 at the German Clinical Trials Register ( https://www.drks.de/drks_web/ ) which is an acknowledged primary register of the World Health Organization ( http://apps.who.int/trialsearch/ ).

A Neglected Topic in Neuroscience: Replicability of fMRI Results With Specific Reference to ANOREXIA NERVOSA

Functional magnetic resonance imaging (fMRI) studies report impaired functional correlates of cognition and emotion in mental disorders. The validity of preexisting studies needs to be confirmed through replication studies, which there is a lack of. So far, most replication studies have been conducted on non-patients (NP) and primarily investigated cognitive and motor tasks. To fill this gap, we conducted the first fMRI replication study to investigate brain function using disease-related food stimuli in patients with anorexia nervosa (AN). Using fMRI, we investigated 31 AN patients and 27 NP for increased amygdala and reduced midcingulate activation when viewing food and non-food stimuli, as reported by the original study (11AN, 11NP; Joos et al., 2011). Similar to the previous study, we observed in the within group comparisons (food>non-food) a frontoinsular activation for both groups. Although in AN the recorded activation clustered more prominently and extended into the cingulate cortex. In the between-group comparisons, the increased amygdala and reduced midcingulate activation could not be replicated. Instead, AN showed a higher activation of the cingulate cortices, the pre-/postcentral gyrus and the inferior parietal lobe. Unlike in the initial study, no significant differences between NP>AN could be observed. The inconsistency of results and the non-replication of the study could have several reasons, such as high inter-individual variance of functional correlates of emotion processing, as well as intra-individual variances and the smaller group size of the initial study. These results underline the importance of replication for assessing the reliability and validity of results from fMRI research.

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]

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.

Self-Criticism and Personality Functioning Predict Patterns of Symptom Change in Major Depressive Disorder

Aim of the study was to identify patient variables that predict specific patterns of symptom course during and after hospital treatment for major depressive disorder (MDD). In a sample of 518 patients, four pairs of clinically relevant patterns of symptom change were contrasted. The time points of measurement were admission, discharge, 3 and 12 month after discharge. CATREG was used to identify the best sets of predictors from 28 variables. A greater reduction in self-criticism during hospital treatment was the strongest predictor of rapid and sustained improvement. Traumatic childhood experiences and lower abilities for communication with others predicted a transient relapse after discharge, while a co-morbid personality disorder and higher level of anxiety differentiated between those with a persistent relapse and those with only a transient relapse in depressive symptoms following discharge. Overall, patients with less severe depression at admission, better abilities in self-perception, and less self-criticism (baseline and/or greater reduction during treatment) showed a better outcome after 1 year. There is limited generalizability to other countries and treatment settings. Data on personality functioning were not available for all patients and findings are correlational in nature. However, findings are in support of a psychotherapeutic focus on a reduction of self-criticism in MDD. Patient with traumatization, a co-morbid personality disorder and lower abilities to communicate their emotional needs should get specific attention and support after discharge from hospital treatment.

The Freiburg sport therapy program for eating disorders: a randomized controlled trial

BACKGROUND

Unhealthy attitudes towards sport and problematic exercise behavior in eating disorders (ED) are common and associated with poorer treatment outcome and higher relapse rates. There is a need to develop and empirically test interventions that could complement standard treatment. The study aimed to assess the efficacy of the Freiburg sport therapy program for eating disorders (FSTP).

METHODS

Outpatients with ED were randomized either to a 3 month sport therapy program (sport therapy group: STG) or a waiting list control group (CG). Patients were assessed when starting the program and at the end of the intervention. The intervention group (STG) was followed up after 6 month. Main outcome criterion was a reduction in unhealthy exercise (Commitment to Exercise Scale, CES). Secondary outcomes encompassed eating pathology (Eating Disorder Examination, EDE), different dimensions of unhealthy exercise (Compulsive Exercise Test, CET subscales) and exercise quantity (accelerometer).

RESULTS

Recruitment was challenging. Fifteen patients were randomized to the STG and 11 were randomized to the CG condition. There was no statistically significant difference between groups according to the main outcome criterion. However, the STG showed a significantly stronger reduction in avoidance and rule driven behavior (CET subscale) when compared to the CG. Improvements (STG) were maintained at follow up.

CONCLUSIONS

There was no statistically significant difference in the reduction of unhealthy attitudes towards sport and problematic exercise behavior between the intervention and the group, as measured with the Commitment to Exercise Scale. Further findings may point to the effectiveness of the program, but have to be interpreted with caution and verified in further studies. A major limitation is the small sample size.

Follow-Up Treatment After Inpatient Therapy of Patients With Unipolar Depression-Compliance With the Guidelines?

OBJECTIVE

To date, there is only a limited number of studies evaluating the implementation and effects of treatment guidelines. Therefore, this study aimed to determine how many patients diagnosed with a major depression were treated in compliance with the German treatment guideline after hospital treatment, and whether a deviation from the guideline resulted in a less favorable development.

METHODS

Five hundred two patients, which originally participated in the INDDEP-study, were included. Data were collected at admission and discharge from eight different psychosomatic (psychotherapeutic) hospitals in Germany as well as 3 months and 1 year after hospital treatment. Data on depressive symptomatology were assessed by QIDS-C (clinical interviews). By phone interviews, the clinical course and the outpatient treatments were assessed. Statistical analyses compared patients who were treated in compliance with the German treatment guideline with those who were not.

RESULTS

Seventy-nine point one percent of the outpatient treatments complied with the treatment guideline. Eleven point eight percent of the patients were treated with medication only, 60.2% with psychotherapy only, and 28.0% with a combination. There was no difference in the clinical outcome (depression) with regard to guideline compliance. Cases in which deviation from the guideline occurred (20.9%) were younger and had a less severe depressive symptomatology at admission and after hospital treatment.

CONCLUSION

After treatment in a psychosomatic hospital or day hospital, the majority of patients with a depressive disorder received adjacent treatment in accordance with the German guideline and with a clear focus on psychotherapy. Deviations from the guideline did not result in a less favorable course of the illness.

Intimate stimuli result in fronto-parietal activation changes in anorexia nervosa

BACKGROUND

Intimacy is a key psychological problem in anorexia nervosa (AN). Empirical evidence, including neurobiological underpinnings, is however, scarce.

OBJECTIVE

In this study, we evaluated various emotional stimuli including intimate stimuli experienced in patients with AN and non-patients, as well as their cerebral response.

METHODS

Functional magnetic resonance imaging was conducted using stimuli with positive, neutral, negative and intimate content. Participants (14 AN patients and 14 non-patients) alternated between passive viewing and explicit emotion regulation.

RESULTS

Intimate stimuli were experienced less positively in AN patients compared to non-patients. AN patients showed decreased cerebral responses in superior parietal cortices in response to positive and intimate stimuli. Intimate stimuli led to stronger activation of the orbitofrontal cortex, and lower activation of the bilateral precuneus in AN patients. Orbitofrontal responses decreased in AN patients during explicit emotion regulation.

CONCLUSIONS

These results show that intimate stimuli are of particular importance in AN patients, who show experiential differences compared to non-patients and altered activation of orbitofrontal and parietal brain structures. This supports that AN patients have difficulties with intimacy, attachment, self-referential processing and body perception.

Systematic Review: Overlap Between Eating, Autism Spectrum, and Attention-Deficit/Hyperactivity Disorder

Background: Links between eating disorders (EDs) [e.g., anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED)] and the major neurodevelopmental disorders of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) have been repeatedly highlighted. In both ASD and ADHD, these links range from an elevated risk for EDs to common symptomatic overlaps and etiological commonalities with EDs. Methods: We performed a systematic literature search (through July 2019) with Medline via Ovid for epidemiological data on EDs (AN, BN, and BED) in combination with both ASD and ADHD. Results: The reviewed studies showed that, on average, 4.7% of patients with certain ED diagnoses (AN, BN, or BED) received an ASD diagnosis. Reliable data on the prevalence of EDs in ASD samples are still scarce. Comorbid ASD is most commonly diagnosed in patients with AN. The prevalence of ADHD in EDs ranged between 1.6% and 18%. Comorbid ADHD was more often reported in the AN-binge eating/purging subtype and BN than in the AN restrictive subtype. The prevalence of EDs in ADHD ranged between no association and a lifetime prevalence of 21.8% of developing an ED in women with ADHD. Conclusions: Studies on the prevalence rates of EDs in ADHD and ASD and vice versa are heterogeneous, but they indicate frequent association. While there is growing evidence of clinical overlaps between the three disorders, it remains difficult to determine whether overlapping characteristics (e.g., social withdrawal) are due to common comorbidities (e.g., depression) or are instead primarily associated with EDs and neurodevelopmental disorders. Furthermore, prospective studies are required to better understand how these disorders are related and whether ADHD and ASD could be either specific or nonspecific predisposing factors for the development of EDs.

White Matter Abnormalities in the Corpus Callosum in Acute and Recovered Anorexia Nervosa Patients-A Diffusion Tensor Imaging Study

Objective: Severe malnutrition in patients with anorexia nervosa (AN) as well as possible trait-related aberrations lead to pronounced structural brain changes whose reversibility after recovery is currently unclear. Previous diffusion tensor imaging (DTI) studies investigating white matter (WM) microstructure alterations in AN are inconsistent. Methods: In this so far largest DTI study in adults, we investigated 33 AN patients, 20 recovered (REC), and 33 healthy women. DTI data were processed using the "DTI and Fiber tools," and the Computational Anatomy Toolbox. WM integrity, both in terms of fractional anisotropy (FA) and mean diffusivity (MD), was assessed. Results: We found a significant FA decrease in the corpus callosum (body) and an MD decrease in the posterior thalamic radiation in the AN group. The REC group displayed FA decrease in the corpus callosum in comparison to HC, whereas there were no MD differences between the REC and HC groups. Conclusion: Despite prolonged restoration of weight in the REC group, no significant regeneration of WM integrity in terms of FA could be observed. Transient changes in MD likely represent a reversible consequence of the acute state of starvation or result from dehydration. Reduction of FA either may be due to WM damage resulting from malnutrition or may be considered a pre-morbid marker.

Association of Leptin Gene DNA Methylation With Diagnosis and Treatment Outcome of Anorexia Nervosa

Epigenetic alterations are increasingly implicated in the pathophysiology of anorexia nervosa (AN) but are as yet poorly understood. We investigated possible associations between the leptin gene (LEP) and the leptin receptor gene (LEPR) DNA promoter methylation and (1) a diagnosis of AN and (2) outcome after a 10 months psychotherapeutic outpatient treatment. 129 (LEPR: n = 135) patients with AN were investigated during the large scale psychotherapeutic Anorexia Nervosa Treatment Outpatient Study (ANTOP) trial, compared to 117 (LEPR: n = 119) age and height matched, normal-weight healthy controls. Blood samples were taken at baseline, the end of therapy (40 weeks) and the 12-months follow-up and compared to controls. Methylation was measured in whole blood via bisulfite sequencing. Within the promoter region 32 (LEP) and 39 CpG sites (LEPR) were analyzed. Two key findings were observed. First, LEP and LEPR methylation at baseline were lower in patients compared to controls (LEP: [%] AN: 30.94 ± 13.2 vs. controls: 34.53 ± 14.6); LEPR ([%] AN: 3.73 ± 5.4 vs. controls: 5.22 ± 8.3, mixed linear models: both P < 0.001). Second, lower DNA methylation of the LEP promoter, with a dynamic upregulation during treatment, was associated with a full recovery in AN patients (% change from baseline to follow-up in full recovery patients: +35.13% (SD: 47.56); mixed linear model: P < 0.0001). To test for potential predictive properties of mean LEP DNA methylation a LEP DNA methylation cut-off (31.25% DNA methylation) was calculated, which significantly discriminated full recovery vs. full syndrome AN patients. This cut-off was then tested in a group of previously unclassified patients (missing follow-up data of the Structured Interview for Anorexic and Bulimic disorders; n = 33). Patients below the cut-off (31.25% LEP DNA methylation) showed an increase in BMI over time, while those above the cut-off had a decrease in BMI (ANOVA at the 12-months follow-up: P = 0.0142). To our knowledge, this is the first study investigating epigenetic alterations in AN over time. Our findings indicate that LEP DNA methylation might be involved in the disease course of AN.

Muscle Dysmorphic Disorder Inventory (MDDI): Validation of a German version with a focus on gender

Muscle dysmorphia (MD) is a condition that is characterized by body image disturbance, a drive for muscularity and excessive exercising. It leads to considerable functional impairment. Most previous studies focused on male samples. The study aimed to validate a German version of the Muscle Dysmorphic Disorder Inventory (MDDI) in order to make the instrument available in German speaking countries. We further aimed to explore for gender differences in the MDDI factors (measurement invariance) and to assess the relationship between MD and positive dimensions of body experience as well as exercise dependence. 394 participants (53% females, mean age 24.3 years) took part in an internet-based survey. The three-factor structure of the English version of the MDDI was replicated, independent of gender (multi group CFA; Base model TLI = .961; CFI = .970). Cronbach´s alpha was .81-.84 for the subscales and .75 for the MDDI total score. MD was associated with exercise dependence and negatively correlated with dimensions of positive body experience, which can be considered relevant for satisfying relationships and a positive sense of self: e.g. body contact and sexual fulfillment. Men and women showed differences in two subscales of the MDDI (appearance intolerance, drive for size). Testing for measurement invariance resulted in weak invariance: Equivalent factor structure for men and women, but significantly different loadings and coefficients. No statistically significant difference in the MDDI total score was found. The findings suggest good psychometric properties of the German version of the MDDI. Future studies should address the question of cut-off scores and norms for different samples as well as a possible overlap between MD and eating disorder psychopathology in women.

Patterns of symptom change in major depression: Classification and clustering of long term courses

To evaluate treatment effects in depression, it is important to monitor change during treatment and also to follow up for a reasonably long time. Describing the variability of symptom change trajectories is useful to better predict long-term status and to improve interventions. Outcome data (N__complete = 518, 4 time points, 1 year of observation time) from a large naturalistic multi-center study on the effects of inpatient and day hospital treatment of unipolar depression were used to identify clusters of symptom trajectories. Common outcome classifications and statistical methods of longitudinal cluster analysis were applied. However, common outcome classifications (in terms of e.g. remission, relapse or recurrence) were not exhaustive, as 49.3% of the trajectories could not be allocated to its classes. Longitudinal cluster analysis reveals 7 clusters (fast response, slow response, retarded response, temporary or persistent relapse, recurrence, and nonresponse). Nonresponse at the end of treatment was a predictor of poor outcome at long term follow up. The classification of patterns of symptom change in depression should be extended. Longitudinal cluster analysis seems a valid option to analyze outcome trajectories over time if a limited number of time points of measurement are available.

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.

Contingency Contracts for Weight Gain of Patients with Anorexia Nervosa in Inpatient Therapy: Practice Styles of Specialized Centers

The treatment of patients with anorexia nervosa (AN) is often challenging, due to a high degree of ambivalence towards recovery and weight gain these patients often express. One part of the multimodal treatment is the utilization of treatment contracts (i.e., contingency contracts) that aim to motivate patients to gain weight by applying positive and negative consequences for the (non-)achievement of weight goals. The main aim of this study is to assess and analyze current standards of contingency contracts’ utilization in German eating disorder centers. n = 76 mental health professionals of twelve specialized university centers in Germany that are currently or were formerly treating patients with AN in an inpatient setting participated. Most experts use contingency contracts in their clinic with weekly weight goals ranging between 500 and 700 g. Overall effectiveness and significance of contingency contracts for the inpatient treatment of patients with AN was rated high. Typical characteristics of a contingency contract in specialized German university hospital centers, such as the most frequent consequences, are described. The survey results assist the planning of further studies aiming to improve the multimodal treatment of patients with AN. For clinical practice, using external motivators such as contingency contracts as well as targeting internal motivation (e.g., by using motivational interviewing) is proposed.

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.

Neural correlates of intimate picture stimuli in females

Jacob et al. (2011) previously reported on intimate picture stimuli for emotion research in females in Psychiatry Research. Difficulties to engage in intimate relations constitute problems of many mental disorders, and intimacy must be differentiated from pure sex drive. Functional neuroimaging is an important tool to understand the pathophysiology of psychiatric disorders. We now studied cerebral activation in response to intimate stimuli in 35 healthy women. Comparison stimuli were taken from the International Affective Picture System. Neuroimaging revealed increased activation in bilateral occipitotemporal, parietal and anterior cingulate cortices extending to the orbitofrontal area. These data reflect cognitive, emotional and motivational compounds congruent with previous neuroimaging data of attachment and long term romantic relationships. Lateral prefrontal, posterior insular regions and the fusiform face area were more active during control images. Our data present a solid basis for use in psychiatric samples.

Psychotherapeutic Treatment for Anorexia Nervosa: A Systematic Review and Network Meta-Analysis

Background: The aim of the study was a systematic review of studies evaluating psychotherapeutic treatment approaches in anorexia nervosa and to compare their efficacy. Weight gain was chosen as the primary outcome criterion. We also aimed to compare treatment effects according to service level (inpatient vs. outpatient) and age group (adolescents vs. adults). Methods:The data bases PubMed, Cochrane Library, Web of Science, Cinahl, and PsychInfo were used for a systematic literature search (until Feb 2017). Search terms were adapted for data base, combining versions of the search terms anorexia, treat^*/therap^* and controlled trial. Studies were selected using pre-defined in- and exclusion criteria. Data were extracted by two independent coders using piloted forms. Network-meta-analyses were conducted on all RCTs. For a comparison of service levels and age groups, standard mean change (SMC) statistics were used and naturalistic, non-randomized studies included. Results: Eighteen RCTs (trials on adults: 622 participants; trials on adolescents: 625 participants) were included in the network meta-analysis. SMC analyses were conducted with 38 studies (1,164 participants). While family-based approaches dominate interventions for adolescents, individual psychotherapy dominates in adults. There was no superiority of a specific approach. Weight gains were more rapid in adolescents and inpatient treatment. Conclusions: Several specialized psychotherapeutic interventions have been developed and can be recommended for AN. However, adult and adolescent patients should be distinguished, as groups differ in terms of treatment approaches considered suitable as well as treatment response. Future trials should replicate previous findings and be multi-center trials with large sample sizes to allow for subgroup analyses. Patient assessment should include variables that can be considered relevant moderators of treatment outcome. It is desirable to explore adaptive treatment strategies for subgroups of patients with AN. Identifying and addressing maintaining factors in AN remains a major challenge.

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.

Cost-effectiveness of focal psychodynamic therapy and enhanced cognitive-behavioural therapy in out-patients with anorexia nervosa

BACKGROUND

Anorexia nervosa (AN) is a serious illness leading to substantial morbidity and mortality. The treatment of AN very often is protracted; repeated hospitalizations and lost productivity generate substantial economic costs in the health care system. Therefore, this study aimed to determine the differential cost-effectiveness of out-patient focal psychodynamic psychotherapy (FPT), enhanced cognitive-behavioural therapy (CBT-E), and optimized treatment as usual (TAU-O) in the treatment of adult women with AN.

METHOD

The analysis was conducted alongside the randomized controlled Anorexia Nervosa Treatment of OutPatients (ANTOP) study. Cost-effectiveness was determined using direct costs per recovery at 22 months post-randomization (n = 156). Unadjusted incremental cost-effectiveness ratios (ICERs) were calculated. To derive cost-effectiveness acceptability curves (CEACs) adjusted net-benefit regressions were applied assuming different values for the maximum willingness to pay (WTP) per additional recovery. Cost-utility and assumptions underlying the base case were investigated in exploratory analyses.

RESULTS

Costs of in-patient treatment and the percentage of patients who required in-patient treatment were considerably lower in both intervention groups. The unadjusted ICERs indicated FPT and CBT-E to be dominant compared with TAU-O. Moreover, FPT was dominant compared with CBT-E. CEACs showed that the probability for cost-effectiveness of FTP compared with TAU-O and CBT-E was ⩾95% if the WTP per recovery was ⩾€9825 and ⩾€24 550, respectively. Comparing CBT-E with TAU-O, the probability of being cost-effective remained <90% for all WTPs. The exploratory analyses showed similar but less pronounced trends.

CONCLUSIONS

Depending on the WTP, FPT proved cost-effective in the treatment of adult AN.

How do patients with anorexia nervosa "process" psychotherapy between sessions? A comparison of cognitive-behavioral and psychodynamic interventions

OBJECTIVE

Patients' processing of psychotherapy between sessions ("inter-session process" (ISP)) has been repeatedly shown to be related to outcome. The aim of this study was to compare ISP characteristics of cognitive-behavioral vs. psychodynamic psychotherapy in the treatment of anorexia nervosa (AN) and their relation to outcome.

METHODS

Data of 106 patients participating in a randomized-controlled trial who received either 40 sessions of enhanced cognitive-behavioral therapy (CBT-E) or focal psychodynamic therapy (FPT) were analyzed. The ISP was measured with the Inter-session Experience Questionnaire (IEQ). Three outcome classes were distinguished: full recovery, partial recovery, and still fulfilling all AN criteria.

RESULTS

Patients receiving CBT-E reported more on "applying therapy" in the initial and the final treatment phase compared to FPT patients. In terms of process-outcome relations, higher levels of "recreating the therapeutic dialogue between sessions," "recreating the therapeutic dialogue with negative emotions" as well as "applying therapy with negative emotions" in the final phase of treatment predicted negative outcome in FPT, whereas overall higher levels of negative emotions predicted negative outcome in CBT-E.

CONCLUSIONS

In outpatient treatment in AN, the processing of therapy as measured by the IEQ showed surprisingly few differences between CBT-E and FPT. However, different ISP patterns were predictive of outcome, pointing to different mechanisms of change.

Predictors of outcomes in outpatients with anorexia nervosa - Results from the ANTOP study

This study aimed to determine predictors of BMI and recovery for outpatients with anorexia nervosa (AN). Patients were participants of the ANTOP (Anorexia Nervosa Treatment of Out-Patients) trial and randomized to focal psychodynamic therapy (FPT), enhanced cognitive behavior therapy (CBT-E), or optimized treatment as usual (TAU-O). N=169 patients participated in the one-year follow-up (T4). Outcomes were the BMI and global outcome (recovery/partial syndrome/full syndrome) at T4. We examined the following baseline variables as possible predictors: age, BMI, duration of illness, subtype of AN, various axis I diagnoses, quality of life, self-esteem, and psychological characteristics relevant to AN. Linear and logistic regression analyses were conducted to identify the predictors of the BMI and global outcome. The strongest positive predictor for BMI and recovery at T4 was a higher baseline BMI of the patients. Negative predictors for BMI and recovery were a duration of illness >6 years and a lifetime depression diagnosis at baseline. Additionally, higher bodily pain was significantly associated with a lower BMI and self-esteem was a positive predictor for recovery at T4. A higher baseline BMI and shorter illness duration led to a better outcome. Further research is necessary to investigate whether or not AN patients with lifetime depression, higher bodily pain, and lower self-esteem may benefit from specific treatment approaches.

Symptom course in inpatient and day clinic treatment of depression: Results from the INDDEP-Study

BACKGROUND

In major depression (MDD), hospital treatment is an option in more severe cases or if outpatient treatment failed. Psychosomatic hospitals in Germany provide treatment programs with multimodal psychotherapy, either in an inpatient or a day hospital setting. In the context of health care research, this study aimed (1) to compare characteristics of patients treated in psychosomatic day hospitals and inpatient units, (2) to compare the effectiveness of both treatment modalities.

METHODS

A naturalistic design was chosen to achieve external validity. 604 consecutive patients were assessed at admission, discharge and a 3-month follow-up. Primary outcome was defined as a reduction of depressive symptomatology (QIDS-C), secondary outcomes comprise overall functioning and quality of life. For a comparison of effectiveness, inpatient and day hospital samples were matched according to known predictors of outcome.

RESULTS

The few differences found between the inpatient and day hospital sample were related to severity of depression and physical impairment. Inpatients more often got antidepressant medication. Additionally, inpatients were treated significantly longer, due to a subgroup of patients with somatic co-morbidity. There were no differences when comparing effectiveness.

LIMITATIONS

When comparing treatment effectiveness, possible bias cannot be ruled out. There was no randomization or untreated control group.

CONCLUSIONS

In patients with a more severe depression and somatic co-morbidity, inpatient treatment might be preferred as compared to day hospital treatment. However, most patients can be treated in both settings.
