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.

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.

[Information about Eating Disorders - the perspective of relatives]. / Informationsbedarf bei Essstörungen ­ die Angehörigenperspektive.

Objectives: This qualitative study aimed to assess the need for information in eating disorders from the perspective of relatives. Further, it examined the question how publicly available information about eating disorders may contribute to psychoeducation. Methods: Thirteen relatives of patients with anorexia nervosa and bulimia nervosa were interviewed based on a semistructured interview guide. The interview transcripts were interpreted by using a structuring qualitative content analysis. Results: Relatives showed a high need for information throughout the entire course of illness. More information about the disorder itself and its potential treatment were requested. The needs were addressed to public services and to family doctors as well as paediatricians. Conclusions: Relatives as well as family doctors and paediatricians play an important role in the detection and support of the treatment of eating disorders. In view of the high rate of cases diagnosed late or not at all, psychoeducational offers require further expansion.

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.

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).

[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.

Motivation-Enhancing Psychotherapy for Inpatients With Anorexia Nervosa (MANNA): A Randomized Controlled Pilot Study.

Patients with anorexia nervosa (AN) are frequently characterized by an unstable readiness to change and high ambivalence toward treatment. Enhancing readiness to behavioral change therefore plays an essential role for adherence to treatment especially for severely ill patients treated in inpatient settings. Therefore, a novel 10 week program for the individual psychotherapy sessions was designed using elements from motivational interviewing to be applied within the multidisciplinary inpatient treatment for patients with AN. In a randomized controlled pilot trial, N = 22 patients with AN received either the new intervention or treatment as usual in one of two recruiting university hospitals. Readiness to change, eating disorder pathology, therapeutic alliance as well as acceptance and feasibility of the new intervention were measured from patients and therapists in week 1, 5, and 10 of inpatient treatment. Results confirm acceptance and feasibility of the MANNA intervention as evaluated by patients as well as therapists. Patients receiving the new intervention completed their inpatient treatment significantly more often on regular terms than patients receiving treatment as usual. No differences between the groups could be found concerning therapeutic alliance during and at the end of treatment and readiness to change. Absolute numbers of BMI increase indicate a larger increase in the intervention group albeit not significant in this pilot study sample. Limitations of the study such as the small sample size as well as possible adaptions and advancements of the intervention that need to be examined in a larger clinical trial of efficacy are discussed. This phase II study is registered with the German Clinical Trials Register (DRKS) under the trial number DRKS00015639.

Depression screening using patient-targeted feedback in general practices: study protocol of the German multicentre GET.FEEDBACK.GP randomised controlled trial.

INTRODUCTION: Approximately one out of six patients in primary care suffers from depression, which often remains undetected. Evidence regarding the efficacy of depression screening in primary care, however, is inconsistent. A previous single-centre randomised controlled trial (RCT) in cardiac patients, the DEPSCREEN-INFO trial, provided the first evidence that written feedback to patients following a positive depression screening reduces depression severity and leads to more comprehensive patient engagement in mental healthcare. To amplify these effects, the feedback should be tailored according to patients' needs and preferences. The GET.FEEDBACK.GP RCT will test the efficacy of this patient-targeted feedback intervention in primary care. METHODS AND ANALYSIS: The multicentre three-arm GET.FEEDBACK.GP RCT aims to recruit a total of 1074 primary care patients from North, East and South Germany. Patients will be screened for depression using the Patient Health Questionnaire-9 (PHQ-9). In the case of a positive depression screening result (PHQ-9 score ≥10), the participant will be randomised into one of three groups to either receive (a) patient-targeted and general practitioner (GP)-targeted feedback regarding the depression screening results, (b) only GP-targeted feedback or (c) no feedback. Patients will be followed over a period of 12 months. The primary outcome is depression severity (PHQ-9) 6 months after screening. Secondary outcomes include patient engagement in mental healthcare, professional depression care and cost-effectiveness. According to a statistical analysis plan, the primary endpoint of all randomised patients will be analysed regarding the intention-to-treat principle. ETHICS AND DISSEMINATION: The Ethics Committee of the Hamburg Medical Association approved the study. A clinical trial company will ensure data safety, monitoring and supervision. The multicentre GET.FEEDBACK.GP RCT is the first trial in primary care that tests the efficacy of a patient-targeted feedback intervention as an adjunct to depression screening. Its results have the potential to influence future depression guidelines and will be disseminated in scientific as well as patient-friendly language. TRIAL REGISTRATION NUMBER: NCT03988985.

Treatment of Anorexia Nervosa-New Evidence-Based Guidelines.

Anorexia nervosa is the most severe eating disorder; it has a protracted course of illness and the highest mortality rate among all psychiatric illnesses. It is characterised by a restriction of energy intake followed by substantial weight loss, which can culminate in cachexia and related medical consequences. Anorexia nervosa is associated with high personal and economic costs for sufferers, their relatives and society. Evidence-based practice guidelines aim to support all groups involved in the care of patients with anorexia nervosa by providing them with scientifically sound recommendations regarding diagnosis and treatment. The German S3-guideline for eating disorders has been recently revised. In this paper, the new guideline is presented and changes, in comparison with the original guideline published in 2011, are discussed. Further, the German guideline is compared to current international evidence-based guidelines for eating disorders. Many of the treatment recommendations made in the revised German guideline are consistent with existing international treatment guidelines. Although the available evidence has significantly improved in quality and amount since the original German guideline publication in 2011, further research investigating eating disorders in general, and specifically anorexia nervosa, is still needed.

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.

Manualised Cognitive Behaviour Therapy for Anorexia Nervosa: Use of Treatment Modules in the ANTOP Study.

Standardised treatment manuals facilitate therapy planning and enhance comparability for research purposes. Within the Anorexia Nervosa Treatment of Out Patients (ANTOP) study, the largest multisite outpatient intervention trial in anorexia nervosa (AN) to date, manualised enhanced cognitive-behavioural therapy (CBT-E) was offered as one treatment modality. The manual consisted of 9 modules, of which Motivation, Nutrition, Formulation and Relapse Prevention were compulsory. Homework worksheets were provided, to ensure the transfer of therapeutic improvements to daily life. This study investigated the use of modules and worksheets in order to explore practice styles of trained therapists in the treatment of AN. This secondary analysis was based on log-sheets (n = 2604) CBT-E therapists completed after each session. Frequencies of modules and worksheets used across all sessions were calculated. Relationships, such as that between use of module and duration of illness, were examined. The most commonly used module was Motivation. In patients with longer illness duration, the module Self Esteem seemed to be particularly important. The worksheet Scales, balancing the pros and cons of AN, was prioritised by therapists. The results underline the importance of motivational work in the treatment of AN, including validating the ambivalence experienced by most AN patients. With increasing duration of illness, resource-oriented elements, such as self esteem stabilisation, should be of focus.

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.

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.

The effectiveness of contingency management in the treatment of patients with anorexia nervosa: A systematic review.

Contingency management in stipulating weight gain is routinely used in the treatment of anorexia nervosa, however, empirical investigations concerning its effectiveness have been scarce. This systematic review was conducted according to the PRISMA statement. Of N = 973 hits, 42 full-texts were included in the qualitative synthesis (11 theoretical texts, 19 case reports, 12 descriptive, cohort, and controlled trials). A central topic in the included publications concerns the enhancement of patients' autonomy through participation in the contingency management process. This heightened autonomy is achieved by using contingency contracts. Positive short-term effects on weight gain were shown, whereas follow-up results were heterogeneous. Although contingency contracts are widely used in clinical practice, our systematic review shows that empirical evidence on underlying mechanisms and efficacy is still scarce. Using an explicit treatment contract can enhance patients' motivation, compliance, and autonomy. Clinical practice should see further development including innovative motivation enhancing and conflict dissolving techniques in addressing the pronounced ambivalence often shown by patients with anorexia nervosa.

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.

The relationship of body image with symptoms of depression and anxiety in patients with anorexia nervosa during outpatient psychotherapy: Results of the ANTOP study.

Body image disturbance represents a central characteristic of anorexia nervosa (AN). Depression and anxiety are the most common mental comorbidities in patients with AN. This study aims to investigate the relationship of body image with symptoms of depression and anxiety during outpatient psychotherapy in AN. Analyses were conducted using the data set of the Anorexia Nervosa Treatment Outpatient Study (ANTOP) randomized controlled trial. The ANTOP study included N = 242 females with AN between 18 and 56 years of age. The trial was designed to compare enhanced cognitive behavioral therapy (CBT-E) and focal psychodynamic therapy (FPT) with optimized treatment as usual (TAU-O) for patients with AN. The analyses on body image dimensions were conducted using measures of correlations and multiple linear regression analyses to assess the relationship and longitudinal prediction of symptoms of depression and anxiety by body image dimensions. Results showed that body image perceptions were significantly associated with symptoms of depression and anxiety in patients with AN at all treatment stages. In addition, body image dimensions at early treatment stages predict depression and anxiety in follow-up measurements. The correlation of symptoms of depression and anxiety by body image perceptions increased along treatment course. The persistence of body image disturbance, while body mass index increases under treatment (persistency effect), may constitute a relevant factor contributing to the course of the most common affective comorbidities of depression and anxiety in patients with AN. Body image disturbances in patients with AN should therefore be explicitly targeted within the specialized psychotherapy of affected patients. (PsycINFO Database Record

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.
