Prognostic Risk Factors in Randomized Clinical Trials of Face-to-Face and Internet-Based Psychotherapy for Depression: A Systematic Review and Meta-Regression Analysis

Importance

Variables such as severe symptoms, comorbidity, and sociodemographic characteristics (eg, low educational attainment or unemployment) are associated with a poorer prognosis in adults treated for depressive symptoms. The exclusion of patients with a poor prognosis from RCTs is negatively associated with the generalizability of research findings.

Objective

To compare the prognostic risk factors (PRFs) in patient samples of RCTs of face-to-face therapy (FTF) and internet-based therapy (IBT) for depression.

Data Sources

PsycINFO, Cochrane CENTRAL, and reference lists of published meta-analyses were searched from January 1, 2000, to December 31, 2021.

Study Selection

RCTs that compared FTF (individual or group therapy) and IBT (guided or self-guided interventions) against a control (waitlist or treatment as usual) in adults with symptoms of depression were included.

Data Extraction and Synthesis

Data were extracted by 2 independent observers. The Cochrane revised risk-of-bias tool was used to assess the risk of bias. The study was preregistered with OSF Registries and followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.

Main Outcomes and Measures

The primary outcome was the standardized mean difference (Hedges g effect size) in depressive symptoms at treatment termination (assessed with standard patient self-report questionnaires), with a positive standardized mean difference indicating larger improvements in the intervention compared with those in the control group. Meta-regression analyses were adjusted for the type of control group. Three preregistered and 2 exploratory sensitivity analyses were conducted. A prognostic risk index (PROG) was created that calculated the sum of 12 predefined individual indicators, with scores ranging from 0 to 12 and higher scores indicating that a sample comprised patients with poorer prognoses.

Results

This systematic review and meta-regression analysis identified 105 eligible RCTs that comprised 18 363 patients. In total, 48 studies (46%) examined FTF, and 57 studies (54%) examined IBT. The PROG was significantly higher in the RCTs of FTF than in the RCTs of IBT (FTF: mean [SD], 3.55 [1.75]; median [IQR], 3.5 [2.0-4.5]; IBT: mean [SD], 2.27 [1.66]; median [IQR], 2.0 [1.0-3.5]; z = -3.68, P < .001; Hedges g = 0.75; 95% CI, 0.36-1.15). A random-effects meta-regression analysis found no association of the PROG with the effect size. Sensitivity analyses with outliers excluded and accounting for risk of bias or small-study effects yielded mixed results on the association between the PROG and effect size.

Conclusions and Relevance

The findings of this systematic review and meta-regression analysis suggest that samples of RCTs of FTF vs IBT differ with regard to PRFs. These findings have implications for the generalizability of the current evidence on IBT for depression. More RCTs of internet-based interventions with clinically representative samples are needed, and the reporting of PRFs must be improved.

Innovative moments in low-intensity, telephone-based cognitive-behavioral therapy for depression

Background

Innovative moments (IMs), defined as moments in psychotherapy when patients' problematic patterns change toward more elaborated and adaptive patterns, have been shown to be associated with a clinical change in patients with depression. Thus, far IMs have been studied in face-to-face settings but not in telephone-based cognitive-behavioral therapy (t-CBT). This study investigates whether IMs occur in t-CBT and examines the association between IMs and symptom improvement, and reconceptualization and symptom improvement.

Methods

The therapy transcripts of n = 10 patients with mild to moderate depression (range: 7-11 sessions, in total 94 sessions) undergoing t-CBT were qualitatively and quantitatively analyzed. Symptom severity (Patient Health Questionnaire-9) and IMs (levels and proportions) were assessed for each therapy session. Hierarchical linear models were used to test the prediction models.

Results

The rating of IMs was shown to be feasible and reliable using the Innovative Moments Coding System (IMCS) (84.04% agreement in words coded), which is indicative of the applicability of the concept of IMs in t-CBT. Only reconceptualization IMs were shown to have a predictive value for treatment success (R2 = 0.05, p = 0.01).

Discussion

The results should be interpreted with caution due to the exploratory nature of this study. Due to the telephone setting, it was necessary to adapt the IMCS. Nonetheless, the extent of IMs identified in the low-intensity t-CBT investigated was comparable to IMs in face-to-face therapy. Further studies are needed to clarify the association between IMs and treatment success as a change process, especially for low-intensity treatments.

Acceptance of E-mental health interventions and its determinants among psychotherapists-in-training during the first phase of COVID-19

BACKGROUND

Although E-mental health (EMH) interventions have been shown to be effective in the treatment of mental health problems and empirical knowledge regarding EMH acceptance for different occupations in health care is established, little is known regarding EMH and psychotherapists-in-training. This seems particularly relevant as psychotherapists-in-training will shape the future health care system since they are as being the next generation of psychotherapists. With social distancing measures in place, COVID-19 has led to an increased demand for EMH, which is broadening the way psychological treatments are delivered.

OBJECTIVE

The present study aims to assess the acceptance of EMH and its determinants among psychotherapists-in-training of different EMH modalities and to retrospectively compare current acceptance with pre-COVID-19 times.

METHODS

Altogether, 29 training institutions in Switzerland and 232 training institutions in Germany were contacted, resulting in a sample of N = 216 psychotherapists-in-training (88.4 % female) who filled out the self-administered web-based questionnaire in summer 2020. The acceptance of EMH was assessed considering several different modalities (e.g., videoconference, guided self-help programs) as well as further possible predictors of EMH acceptance based on the Unified Theory of Acceptance and Use of Technology. Acceptance scores were categorized as low, moderate or high based on prior research and predicted using multiple regression.

RESULTS

Acceptance of EMH was moderate (M = 3.40, SD = 1.11) and increased significantly (t(215) = 12.03, p < .01; d = 0.88) compared to pre-COVID-19 (M = 2.67, SD = 1.11); however, acceptance varied significantly between modalities (F(2.6, 561.7) = 62.93, p < .01, partial η² = 0.23), with videoconferencing being the most accepted and unguided programs the least. Stepwise regression including three of 14 variables (R² = 0.55, F (14, 201) = 17.68, p < .001) identified performance expectancy, social influence and concerns about the therapeutic alliance as significant determinants of EMH acceptance.

DISCUSSION

Acceptance by psychotherapists-in-training was moderate and in line with prior research and comparable with other clinicians' acceptance scores. Performance expectancy, social influence and concerns about the therapeutic alliance were predictive of EMH acceptance, indicating their significance in the implementation of EMH in health care.

CONCLUSION

These findings underline the importance of the aforementioned determinants of EMH acceptance and the need for further studies investigating EMH acceptance in order to derive adequate educational programs and to facilitate dissemination among psychotherapists-in-training.

Intensity of Treatment as Usual and Its Impact on the Effects of Face-to-Face and Internet-Based Psychotherapy for Depression: A Preregistered Meta-Analysis of Randomized Controlled Trials

INTRODUCTION

Treatment as usual (TAU) is the most frequently used control group in randomized trials of psychotherapy for depression. Concerns have been raised that the heterogeneity of treatments in TAU leads to biased estimates of psychotherapy efficacy and to an unclear difference between TAU and control groups like waiting list (WL).

OBJECTIVE

We investigated the impact of control group intensity (i.e., amount and degree to which elements of common depression treatments are provided) on the effects of face-to-face and internet-based psychotherapy for depression.

METHODS

We conducted a preregistered meta-analysis (www.osf.io/4mzyd). We included trials comparing psychotherapy with TAU or WL in patients with symptoms of unipolar depression. Six indicators were used to assess control group intensity.

PRIMARY OUTCOME

Standardized mean difference (SMD) of psychotherapy and control in depressive symptoms at treatment termination.

RESULTS

We included 89 trials randomizing 14,474 patients to 113 psychotherapy conditions and 89 control groups (TAU in 42 trials, WL in 47 trials). Control group intensity predicted trial results in preregistered (one-sided ps < 0.042) and exploratory analyses. Psychotherapy effects were significantly smaller (one-sided p = 0.002) in trials with higher intensity TAU (SMD = 0.324, CI 0.209 to 0.439) than in trials with lower intensity TAU (SMD = 0.628, CI 0.455 to 0.801). Psychotherapy effects against lower intensity TAU did not differ from effects against WL (two-sided p = 0.663).

CONCLUSIONS

Our results suggest that variation in TAU intensity impacts the outcome of trials. More scrutiny in the design of control groups for clinical trials is recommended.

Validierung einer Skala zur Erfassung der depressionsbezogenen Selbstwirksamkeitserwartung (DSW)

Zusammenfassung. Erste Befunde indizieren, dass Patientinnen und Patienten mit stark ausgeprägter depressionsbezogener Selbstwirksamkeitserwartung bessere Behandlungsergebnisse erzielen und ein geringeres Rückfallrisiko aufweisen. Bisher existieren jedoch nur englischsprachige validierte Instrumente zur Erfassung des Konstrukts. In der vorliegenden Studie erfolgte eine psychometrische Überprüfung der deutschsprachigen Adaptation (DSW-Skala) der Self-efficacy for Managing Depression Scale ( Bush et al., 2001 ) anhand von N = 377 primärärztlichen Patientinnen und Patienten mit depressiver Symptomatik, die zu Behandlungsbeginn sowie nach 3, 6 und 12 Monaten untersucht wurden. Die Ergebnisse belegten eine gute interne Konsistenz der Skala (Cronbachs α ≥ .85) und akzeptable Retest-Reliabilität ( rtt = .63). Die Responsivität der Skala sowie eine vergleichbare Messstruktur über alle Messzeitpunkte hinweg wurden nachgewiesen. Multiple Regressionsanalysen belegten die Vorhersagekraft der DSW-Skala bezüglich der depressiven Symptomatik über 6 Monate. Die Ergebnisse zeigen, dass die DSW-Skala gängige psychometrische Standards erfüllt, sodass die Skala als zeitökonomisches und reliables Messinstrument in der Praxis und Forschung eingesetzt werden kann.

BDD-NET – Ein internetbasiertes Programm bei Körperunzufriedenheit zur niedrigschwelligen Behandlung der körperdysmorphen Störung für den deutschen Sprachraum

Hintergrund: Die Körperdysmorphe Störung (KDS) ist eine schwerwiegende psychische Störung, die mit starker Scham sowie Leidensdruck und Funktionseinschränkungen einhergeht. Kognitive Verhaltenstherapie stellt die aktuell wirksamste evidenzbasierte Behandlungsmethode dar. Aufgrund zahlreicher Behandlungsbarrieren kommen KDS-Betroffene jedoch selten in der psychotherapeutischen Behandlung an, weshalb niedrigschwelligen Behandlungsmethoden (z.B. aus dem Bereich E-Mental-Health) eine wichtige Rolle zukommen könnten. Erste internationale Studien weisen auf die Wirksamkeit von E-Mental-Health-Angeboten bei KDS hin. Material und Methoden: Dieser Beitrag gibt eine Übersicht zur bisherigen Umsetzung und Evidenz von E-Mental-Health-Angeboten für KDS und stellt die ins Deutsche übersetzte Version des BDD-NET-Programms, eines internetbasierten, manuali­sierten, therapeutenbegleiteten Interventionsprogramms, für die KDS vor, welches aus dem Englischen für den deutschen Sprachraum übersetzt und adaptiert wurde. Ergebnisse: BDD-NET umfasst acht Module, die binnen einer 12-wöchigen Behandlung online bearbeitet werden. Die Online-Plattform bietet für die Patienten die Möglichkeit, mit dem BDD-NET-Therapeuten mittels persönlicher Nachrichten zu kommunizieren. Sämtliche Materialien wurden aus dem Englischen übersetzt und vor allem in kultureller Hinsicht adaptiert. Schlussfolgerungen: BDD-NET könnte ein wichtiger Baustein in der Versorgung von KDS-Betroffenen sein. Die Evaluation steht für den deutschen Sprachraum noch aus. Auf Besonderheiten des Settings (z.B. Störungseinsicht als möglicher Behandlungsfokus) sowie praktische Implikationen wird eingegangen. Zudem werden Voraussetzungen und Rahmenbedingungen für eine perspektivische Dissemination diskutiert.

Body dysmorphic disorder of female genitalia: a qualitative study of Swiss obstetrician-gynecologists' experiences and practices

Purpose

This work focuses on the experiences and practices of obstetrician–gynecologists (ob–gyns) with patients suffering from body dysmorphic disorder (BDD) and issues with their aesthetics, specifically focusing on female genitalia. Ob–gyns are likely to play an important role in the recognition and treatment of women facing such issues.

Methods

This study took a qualitative, explorative approach. Semi-structured interviews were conducted with 11 ob–gyns about their experiences with patients who presented symptoms of BDD of female genitalia, their treatments, and interest in further education and supportive material. Interviews were analyzed through qualitative content analysis.

Results

A categorization system was created. The results showed that the participating ob–gyns are often confronted with genital dissatisfaction of patients. The study sample demonstrated a lack of mental health literacy concerning BDD. The treatments that the ob–gyns of this sample suggested for BDD of female genitalia were not in line with what evidence suggests. Finally, interest in further education and supportive material for consultation was evidenced in this sample.

Conclusions

The findings encourage further studies to identify the recognition of BDD concerning genitalia or etiological factors. Furthermore, practical implications (e.g., need of supportive material) can be derived from the results.

Prevalence of symptoms of body dysmorphic disorder (BDD) and associated features in Swiss military recruits: a self-report survey

BACKGROUND

Body dysmorphic disorder (BDD), defined as the obsessive idea that some aspect of one's own body or appearance is severely flawed/deformed, is relatively common in the general population and has been shown to have strong associations with mood and anxiety disorders and substance abuse disorders. Furthermore, a previous study on symptoms of BDD among people in the military showed that muscles are an important area of preoccupation. Hence, this study aimed to 1. assess the prevalence of BDD symptoms in Swiss military recruits, 2. specify the areas of preoccupation, and 3. analyze associated features (depression and alcohol/drug abuse).

METHOD

A total of 126 Swiss male military recruits (age: M = 20.12, SD = 1.09, range: 18-24) were examined using self-report measurements to assess symptoms of BDD, depression, alcohol/drug abuse.

RESULTS

The results showed that symptoms of BDD were relatively common (9.5% reached the cutoff value for probable BDD, 84% reported some symptoms), with the muscles as the most common area of preoccupation. A positive correlation (r = .38, p < .001) between depressive symptoms and symptoms of BDD was found, thus no correlation between alcohol/drug abuse and symptoms of BDD.

CONCLUSION

The results indicate a need to develop and implement measures for prevention (e.g. raising awareness among the military) and intervention in this specific population.

Long-Term Effects of the Individual Placement and Support Intervention on Employment Status: 6-Year Follow-Up of a Randomized Controlled Trial

People with mental illness often experience difficulties with reintegration into the workplace, although employment is known to assist these individuals in their recovery process. Traditional approaches of "first train, then place" have been recently replaced by supported employment (SE) methods that carry strategy of "first place, then train." Individual placement and support (IPS) is one of the best-studied methods of SE, which core principles are individualized assistance in rapid job search with consequent placement in a paid employment position. A considerable amount of high-quality evidence supported the superiority of IPS over conventional methods in providing improved employment rates, longer job tenure, as well as higher salaries in competitive job markets. Nonetheless, our knowledge about the IPS-mediated long-term effects is limited. This non-interventional follow-up study of a previously published randomized controlled trial (RCT) called ZhEPP aimed to understand the long-term impact of IPS after 6 years since the initial intervention. Participants from the ZhEPP trial, where 250 disability pensioners with mental illnesses were randomized into either IPS intervention group or treatment as usual group (TAU), were invited to face-to-face interviews, during which employment status, job tenure, workload, and salaries were assessed. One hundred and fourteen individuals agreed to participate in this follow-up study. Although during the first 2 years post-intervention, the IPS group had higher employment rates (40% (IPS) vs. 28% (TAU), p < 0.05 at 24 months), these differences disappeared by the time of follow-up assessments (72 months). The results indicated no substantial differences in primary outcome measures between IPS and TAU groups: employment rate (36 vs. 33%), workload (10.57 vs. 10.07 h per week), job tenure (29 vs. 28 months), and salary (20.21CHF vs. 25.02 CHF). These findings provide important insights regarding the long-term effects of IPS among individuals with mental health illnesses. Further research is required to advance the current knowledge about IPS intervention and its years-long impact.

Does symptom severity matter in stepped and collaborative care for depression?

BACKGROUND

We investigated the differential effectiveness of a stepped and collaborative care model (SCM) vs. treatment as usual (TAU) for primary care patients with various depression severity degrees and explored whether subgroups received distinct evidence-based treatments.

METHODS

Subgroup analyses of a RCT were calculated applying a multiple linear mixed model with the factors 1. group (SCM; TAU), 2. severity ((mild-moderate (MMD); severe depression (SD)) and their interaction, with PHQ-9 as primary outcome. Utilization of treatments was analyzed descriptively.

RESULTS

For the 737 participating patients (SCM: n = 569; TAU: n = 168), availability of data substantially varies between subgroups at 12-month follow-up ranging between 37% and 70%. ITT-analysis (Last-observation-carried-forward) revealed a significant interaction for group x severity [p = 0.036] and a significant difference between groups in symptom reduction for MMD (-3.9; [95% CI: -5.1 to -2.6, p < 0.001; d = 0.64] but not for SD (-1.6; [95% CI: -3.4 to 0.2, p = 0.093; d = 0.27]. Sensitivity analyses (multiple imputation, completer analysis, pattern mixture model) didn`t confirm the interaction effect and showed significant effects for both severity groups with slightly higher effect sizes for MMD. Differences between SCM and TAU in the percentage of patients utilizing depression-specific treatments are larger for MMD.

LIMITATIONS

There was a high proportion of missing values among severely depressed patients, especially in SCM.

CONCLUSION

SCM is effective for both MMD and SD. Utilization patterns might help explain the higher effects for MMD. Various strategies of replacement of missing values lead to slightly divergent results due to selective drop out between severity groups.

Cost-effectiveness of guideline-based stepped and collaborative care versus treatment as usual for patients with depression - a cluster-randomized trial

BACKGROUND

Depression is associated with major patient burden. Its treatment requires complex and collaborative approaches. A stepped care model based on the German National Clinical Practice Guideline "Unipolar Depression" has been shown to be effective. In this study we assess the cost-effectiveness of this guideline based stepped care model versus treatment as usual in depression.

METHODS

This prospective cluster-randomized controlled trial included 737 depressive adult patients. Primary care practices were randomized to an intervention (IG) or a control group (CG). The intervention consisted of a four-level stepped care model. The CG received treatment as usual. A cost-utility analysis from the societal perspective with a time horizon of 12 months was performed. We used quality-adjusted life years (QALY) based on the EQ-5D-3L as effect measure. Resource utilization was assessed by patient questionnaires. Missing values were imputed by 'multiple imputation using chained equations' based on predictive mean matching. We calculated adjusted group differences in costs and effects as well as incremental cost-effectiveness ratios. To describe the statistical and decision uncertainty cost-effectiveness acceptability curves were constructed based on net-benefit regressions with bootstrapped standard errors (1000 replications). The complete sample and subgroups based on depression severity were considered.

RESULTS

We found no statically significant differences in costs and effects between IG and CG. The incremental total societal costs (+€5016; 95%-CI: [-€259;€10,290) and effects (+ 0.008 QALY; 95%-CI: [- 0.030; 0.046]) were higher in the IG in comparison to the CG. Significantly higher costs were found in the IG for outpatient physician services and psychiatrist services in comparison to the CG. Significantly higher total costs and productivity losses in the IG in comparison to the CG were found in the group with severe depression. Incremental cost-effectiveness ratios for the IG in comparison to the CG were unfavourable (complete sample: €627.000/QALY gained; mild depression: dominated; moderately severe depression: €645.154/QALY gained; severe depression: €2082,714/QALY gained) and the probability of cost-effectiveness of the intervention was low, except for the group with moderate depression (ICER: dominance; 70% for willingness-to-pay threshold of €50,000/QALY gained).

CONCLUSIONS

We found no evidence for cost-effectiveness of the intervention in comparison to treatment as usual.

The Role of Homework Engagement, Homework-Related Therapist Behaviors, and Their Association with Depressive Symptoms in Telephone-Based CBT for Depression

Background

Telephone-based cognitive behavioral therapy (tel-CBT) ascribes importance to between-session learning with the support of the therapist. The study describes patient homework engagement (HE) and homework-related therapist behaviors (TBH) over the course of treatment and explores their relation to depressive symptoms during tel-CBT for patients with depression.

Methods

Audiotaped sessions (N = 197) from complete therapies of 22 patients (77% female, age: M = 54.1, SD = 18.8) were rated by five trained raters using two self-constructed rating scales measuring the extent of HE and TBH (scored: 0–4).

Results

Average scores across sessions were moderate to high in both HE (M = 2.71, SD = 0.74) and TBH (M = 2.1, SD = 0.73). Multilevel mixed models showed a slight decrease in HE and no significant decrease in TBH over the course of treatment. Higher TBH was related to higher HE and higher HE was related to lower symptom severity.

Conclusions

Results suggest that HE is a relevant therapeutic process element related to reduced depressive symptoms in tel-CBT and that TBH is positively associated with HE. Future research is needed to determine the causal direction of the association between HE and depressive symptoms and to investigate whether TBH moderates the relationship between HE and depressive symptoms.

Barriers to access to outpatient mental health care for refugees and asylum seekers in Switzerland: the therapist's view

BACKGROUND

More than 120,000 refugees and asylum seekers are currently living in Switzerland. The prevalence of mental disorders among this population is significantly higher than that in the general population. While effective treatment options and cross-cultural, specialized treatment centers exist, they tend to be overloaded by their target populations. General outpatient primary health care providers might be able to compensate for the lack of specialized treatment slots. To date, however, it is unknown how often and under what conditions (e.g., length of waiting lists) refugees and asylum seekers are treated outside of specialized centers and whether there are barriers that prevent providers in outpatient settings from treating more patients in this subgroup. The present study aimed to assess the challenges and barriers faced by psychiatrists and psychotherapists working in outpatient settings in Switzerland in treating refugees and asylum seekers to determine the potential capacity of this group to provide mental health care.

METHODS

An online survey was conducted during the winter of 2017/2018. The survey was constructed in three official languages and took 10-15 min to complete. Spearman's correlations, Mann-Whitney U-Tests, and Chi-squared tests were conducted to analyze the data.

RESULTS

Eight hundred and sixty-seven (N = 867) psychotherapists and psychiatrists working in outpatient settings completed the survey: 43% of them reported having treated between 1 and 9 refugees or asylum seekers in the past 12 months, and a further 13% reported treating 10 or more. Interpreters were used for almost every other patient with a refugee or asylum-seeker background. At the same time, the funding of interpreters, as well as the funding of treatment in general, were reported to be the biggest hurdles to treating more refugees and asylum seekers.

CONCLUSIONS

Given the low number of patients rejected for capacity reasons (between 2 and 5%) and the median waiting times for the admission of new patients ranging between 2 and 3 weeks, outpatient primary mental health care providers might treat more refugees and asylum seekers and relieve specialized treatment centers. However, barriers such as lack of funding of interpreters seem to hinder them. Appropriate steps by the authorities are needed to improve the current situation.

[Body Dysmorphic Disorder: Diagnosis, Treatment and Challenges in the General Practice]

Body Dysmorphic Disorder: Diagnosis, Treatment and Challenges in the General Practice Abstract. Body dysmorphic disorder (point prevalence: 1.7-2.4 %) is characterized by excessive preoccupation with one or more subjectively perceived blemishes of the appearance, as a result of which those affected show a high burden of disease due to avoidance behavior and time-consuming rituals, and often secondary problems (including depression, suicidal tendencies). The disorder is often accompanied by pronounced shame and is therefore associated with challenges in diagnostics, which is why the indication and specialist treatment (first-line treatment: cognitive-behavioural therapy) are usually only carried out with great latency. Family doctors can play a key role in diagnosis and treatment because of the often long-standing relationship of trust with their patients. Targeted screening, active and at the same time prudent discussion, as well as knowledge of treatment options and special features of the disease pattern (e.g. fluctuating understanding of the disease, desire for plastic surgery measures) are necessary. Against this background, the article provides an overview of the clinic, diagnostics and therapy and concludes with specific challenges and practical recommendations for family practice.

Antidepressant prescription practice and related factors in Switzerland: a cross-sectional analysis of health claims data

BACKGROUND

The aim of the study was to examine the prevalence of and factors associated with antidepressant (AD) prescriptions in order to draw a comprehensive picture of prescribing practices in Switzerland.

METHOD

We conducted a population-based, cross-sectional descriptive study using a large Swiss healthcare claims database, covering approximately 13% of the Swiss population. AD prescription was determined by identifying patients (N = 105,663) with health claims data of at least 1 AD prescription in the year 2016. AD medication was identified using ATC-codes classified by the World Health Organisation. Univariate, bivariate and multivariate analyses using logistic regression were performed.

RESULTS

The extrapolated 1-year prevalence of AD prescription was 8.7% (95% CI, 8.7-8.8) with two thirds of AD recipients being female and the average age being 59 years (SD = 19.1). The regional distribution of prescription rates varied between cantons and ranged from 6.5 to 11.7%. Logistic regression revealed higher prescription rates among females compared to males (OR: 1.52) and an increased probability of AD prescription by age up until 54 years (OR: 2.25) and ≥ 85 years (OR: 2.32). Comorbidity is associated with higher odds (OR: 3.26 with 1-2 comorbidities) and enrollment in a managed care plan (compared to standard care) with lower odds for an AD prescription (OR: 0.85).

CONCLUSION

This study is the first in Switzerland to describe the prevalence of and factors associated with AD prescription based on a large health claims database reflecting routine care. The results provide important information about regional variation, prescription source, and potential over-prescription in the treatment of depressive disorders.

[Advice Literature on Depression: How Evidence-Based is it?]

INTRODUCTION

Advice literature on depression for patients and their relatives is a widespread and low-threshold source of information. In terms of empowerment of the patients it can contribute to the early detection and effective treatment of the disorder. An evaluation of its content quality, particularly its evidence base, is still missing. Considering this, the content of advice literature on depression is reviewed by comparing it systematically with content and recommendations from the German S3-/NV-guideline on unipolar depression.

METHODS

Based on a systematic search within the data base of the book trade, the 30 most widespread German advice books were analysed. For this purpose a rating instrument (RLP-D) with 54 items on diagnostics and treatment was derived from the current S3-/NV-guideline. With the help of the RLP-D one rater analysed both elaboration and accuracy of the 30 books' content.

RESULTS

Between 7.4 and 81.5% of the items i. e. of the guideline content, are missing in the analysed advice books (Mdn=25.9%, IQR=22.7%). On average a third of the 54 items is covered extensively as well as without contradictions to the guideline (Mdn=36.1%, IQR=17.1%, Range: 1.9-64.8%). A fifth of the covered items (Mdn=20.4%; IQR=19.0%, Range: 2.9-47.6%) shows clinically relevant contradictions to the guideline content. Information about psychotherapy and pharmacotherapy as treatment options is the content which is covered extensively and correctly most often: The information is given in more than 83% of the books.

DISCUSSION

There is a substantial variability concerning the elaboration and accuracy of the diagnostics and treatment content in advice literature. This also applies to the especially concerning erroneous content in advice literature. The further evaluation of the rating instrument RLP-D is a next important step. An application and reduction to the core contents of the guideline could facilitate the currently rather complex and laborious rating system.

CONCLUSION

Although some basic information is given in almost all of the analysed books, advice literature on depression cannot be recommended per se due to the large differences in quality. Systematic evaluations of quality should be established in order to facilitate a well-grounded choice of literature in order to improve the information for patients.

Comparative effectiveness of continuation and maintenance treatments for persistent depressive disorder in adults

BACKGROUND

Persistent depressive disorder (PDD) is defined as a depressive disorder with a minimum illness duration of two years, including four diagnostic subgroups (dysthymia, chronic major depression, recurrent major depression with incomplete remission between episodes, and double depression). Persistent forms of depression represent a substantial proportion of depressive disorders, with a lifetime prevalence ranging from 3% to 6% in the Western world. Growing evidence indicates that PDD responds well to several acute interventions, such as combined psychological and pharmacological treatments. Yet, given the high rates of relapse and recurrences of depression following response to acute treatment, long-term continuation and maintenance therapy are of great importance. To date, there has been no evidence synthesis available on continuation and maintenance treatments of PDDs.

OBJECTIVES

To assess the effects of pharmacological and psychological (either alone or combined) continuation and maintenance treatments for persistent depressive disorder, in comparison with each other, placebo (drug/attention placebo/non-specific treatment control), and treatment as usual (TAU). Continuation treatments are defined as treatments given to currently remitted people (remission is defined as depressive symptoms dropping below case level) or to people who previously responded to an antidepressant treatment. Maintenance therapy is given during recovery (which is defined as remission lasting longer than six months).

SEARCH METHODS

We searched Ovid MEDLINE (1950- ), Embase (1974- ), PsycINFO (1967- ) and the Cochrane Central Register of Controlled Trials (CENTRAL) to 28 September 2018. An earlier search of these databases was also conducted for RCTs via the Cochrane Common Mental Disorders Controlled Trial Register (CCMD-CTR) (all years to 11 Dec 2015). In addition we searched grey literature resources as well as the international trial registers ClinicalTrials.gov and ICTRP to 28 September 2018. We screened reference lists of included studies and contacted the first author of all included studies.

SELECTION CRITERIA

We included randomized (RCTs) and non-randomized controlled trials (NRCTs) in adults with formally diagnosed PDD, receiving pharmacological, psychological, or combined continuation and maintenance interventions.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies and extracted and analyzed data. The primary efficacy outcome was relapse/recurrence rate of depression. The primary acceptance outcome was dropout due to any reason other than relapse/recurrence. We performed random-effects meta-analyses using risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI).

MAIN RESULTS

We included 10 studies (seven RCTs, three NRCTs) involving 840 participants in this review, from which five studies investigated continuation treatments and five studies investigated maintenance treatments. Overall, the included studies were at low-to-moderate risk of bias. For the three NRCTs, the most common source of risk of bias was selection of reported results. For the seven RCTs, the most common sources of risk of bias was non-blinding of outcome assessment and other bias (especially conflict of interest due to pharmaceutical sponsoring).Pharmacological continuation and maintenance therapiesThe most common comparison was antidepressant medication versus tablet placebo (five studies). Participants taking antidepressant medication were probably less likely to relapse or to experience a recurrent episode compared to participants in the placebo group at the end of the intervention (13.9% versus 33.8%, RR 0.41, 95% CI 0.21 to 0.79; participants = 383; studies = 4; I² = 54%, moderate quality evidence). Overall dropout rates may be similar between participants in the medication and placebo group (23.0% versus 25.5%, RR 0.90, 95% CI 0.39 to 2.11; RCTs = 4; participants = 386; I² = 64%, low quality evidence). However, sensitivity analyses showed that the primary outcome (rate of relapse/recurrence) showed no evidence of a difference between groups when only including studies with low risk of bias.None of the studies compared pharmacological or psychological treatments versus TAU.Psychological continuation and maintenance therapiesOne study compared psychological therapies versus attention placebo/non-specific control. One study compared psychotherapy with medication. The results of the studies including psychotherapy might indicate that continued or maintained psychotherapy could be a useful intervention compared to no treatment or antidepressant medication. However, the body of evidence for these comparisons was too small and uncertain to draw any high quality conclusions.Combined psychological and pharmacological continuation and maintenance therapiesThree studies compared combined psychological and pharmacological therapies with pharmacological therapies alone. One study compared combined psychological and pharmacological therapies with psychotherapeutic therapies alone. However, the body of evidence for these comparisons was too small and uncertain to draw any high quality conclusionsComparison of different antidepressant medications Two studies reported data on the direct comparison of two antidepressants. However, the body of evidence for this comparison was too small and uncertain to draw any high quality conclusions.

AUTHORS' CONCLUSIONS

Currently, it is uncertain whether continued or maintained pharmacotherapy (or both) with the reviewed antidepressant agents is a robust treatment for preventing relapse and recurrence in people with PDD, due to moderate or high risk of bias as well as clinical heterogeneity in the analyzed studies.For all other comparisons, the body of evidence was too small to draw any final conclusions, although continued or maintained psychotherapy might be effective compared to no treatment. There is need for more high quality trials of psychological interventions. Further studies should address health-related quality of life and adverse events more precisely, as well as assessing follow-up data.

Effectiveness of Telephone-Administered Cognitive-Behavioral Psychotherapy for Depression With Versus Without Additional Letters: A Randomized Controlled Trial

Background: Telephone-administered cognitive-behavioral psychotherapy (T-CBT) can effectively treat patients with depressive symptoms. Introduction: We investigated whether adding letters (via postal mail) to T-CBT reduces depressive symptoms and increases response and remission. Additionally, we assessed whether T-CBT reduced all patients' symptoms in the first depression-specific T-CBT sample in German healthcare. Materials and Methods: Primary care patients were randomized to T-CBT with versus without letters. All received 1 face-to-face and 8-12 telephone-administered sessions. An intention-to-treat sample was analyzed. Between-groups differences in symptom change and the total sample's symptom change were computed using linear mixed models with group as fixed effect, referring general practice as random effect and several covariates. Differences in response and remission were assessed using logistic regressions. Results: Fifty-nine patients were referred to T-CBT and randomized. Twenty-six patients actually participated in T-CBT with letters and 21 without letters. The groups did not differ significantly regarding symptom change (Patient Health Questionnaire [PHQ-9]) from baseline to end: T-CBT without letters showed 1.05 points greater reduction (95% confidence interval: -4.72 to 2.62; p = 0.56; Cohen's d = -0.12) (adjusted mean change). The groups did not differ significantly regarding symptom change from baseline to 6-month follow-up nor odds of response or remission. The total sample's PHQ-9 showed significant adjusted mean reduction from baseline to end of T-CBT and to 6-month follow-up. Discussion: Additional letters did not lead to greater symptom reduction. Overall results for the first German T-CBT intervention for depression appear promising but require further assessment using a control condition. Conclusions: Additional letters do not appear to enhance the effectiveness of T-CBT.

Treatment selection and treatment initialization in guideline-based stepped and collaborative care for depression

In order to optimize patient allocation, guidelines recommend stepped and collaborative care models (SCM) including low-intensity treatments. The aim of this study is to investigate the implementation of guideline-adherent treatments in a SCM for depression in routine care. We analyzed care provider documentation data of n = 569 patients treated within a SCM. Rates of guideline-adherent treatment selections and initializations as well as accordance between selected and initialized treatment were evaluated for patients with mild, moderate and severe depression. Guideline-adherent treatment selection and initialization was highest for mild depression (91% resp. 85%). For moderate depression, guideline-adherent treatments were selected in 68% and applied in 54% of cases. Guideline adherence was lowest for severe depression (59% resp. 19%). In a multiple mixed logistic regression model a significant interaction between guideline adherence in treatment selection/initialization and severity degree was found. The differences between treatment selection and initialization were significant for moderate (OR: 1.8 [95% CI: 1.30 to 2.59; p = 0.0006]) and severe depression (OR: 6.9; [95% CI: 4.24 to 11.25; p < .0001] but not for mild depression (OR = 1.8, [95%-CI: 0.68 to 4.56; p = 0.2426]). Accordance between selected and initialized treatment was highest for mild and lowest for severe depression. We conclude that SCMs potentially improve care for mild depression and guideline adherence of treatment selections. Guideline adherence of treatment initialization and accordance between treatment selection and initialization varies with depression severity. Deficits in treating severe depression adequately may be more a problem of failed treatment initializations than of inadequate treatment selections.

Guideline-based stepped and collaborative care for patients with depression in a cluster-randomised trial

Guidelines recommend stepped and collaborative care models (SCM) for depression. We aimed to evaluate the effectiveness of a complex guideline-based SCM for depressed patients. German primary care units were cluster-randomised into intervention (IG) or control group (CG) (3:1 ratio). Adult routine care patients with PHQ-9 ≥ 5 points could participate and received SCM in IG and treatment as usual (TAU) in CG. Primary outcome was change in PHQ-9 from baseline to 12 months (hypothesis: greater reduction in IG). A linear mixed model was calculated with group as fixed effect and practice as random effect, controlling for baseline PHQ-9 (intention-to-treat). 36 primary care units were randomised to IG and 13 to CG. 36 psychotherapists, 6 psychiatrists and 7 clinics participated in SCM. 737 patients were included (IG: n = 569 vs. CG: n = 168); data were available for 60% (IG) and 64% (CG) after 12 months. IG showed 2.4 points greater reduction [95% confidence interval (CI): -3.4 to -1.5, p < 0.001; Cohen's d = 0.45] (adjusted PHQ-9 mean change). Odds of response [odds ratio: 2.8; 95% CI: 1.6 to 4.7] and remission [odds ratio: 3.2; 95% CI: 1.58 to 6.26] were higher in IG. Guideline-based SCM can improve depression care.

Identifying relapse prevention elements during psychological treatment of depression: Development of an observer-based rating instrument

BACKGROUND

Although observer-rated instruments assessing therapist's adherence to relapse-preventive treatments are available, they do not adequately cover specific relapse-preventive elements that focus on implementation of strategies after terminating treatment. This study describes the development of the KERI-D (Kodierbogen zur Erfassung Rückfallprophylaktischer Interventionen bei Depression/Coding System to Assess Interventions of Relapse Prevention in Depression). The KERI-D is a new observer-based rating tool for acute or continuation/maintenance-phase sessions and assesses relapse-prevention elements including implementation into patient's daily routines.

METHODS

The development of the KERI-D included iterative steps referring to theoretical, clinical and empirical sources. It consists of 19 content items within four categories (self-care, early warning signs, triggering events/situations, termination of therapy) and one global item. For empirical analyses, videotaped psychotherapy sessions of 36 psychotherapies were rated by three independent observers and analyzed for their psychometric properties.

RESULTS

Most items showed moderate to good inter-rater reliability (median ICC = .80) and retest reliability (median ICC = .93). Principal-axis factor analysis revealed three subscales, and first evidence of content validity was demonstrated. No associations with clinical follow-up data were found.

LIMITATIONS

Analysis was limited to a relatively small sample of selected psychotherapy sessions. Evaluation of predictive validity is a desirable next step to further examine applicability and scope of the instrument.

CONCLUSIONS

The KERI-D is the first observer-based rating instrument measuring specific relapse-prevention strategies in psychotherapy for depression. It may help to identify elements that prove effective in reducing relapse/recurrence in the long-term and thereby help to optimize effect duration of depression treatment.

Effectiveness of telephone-based aftercare case management for adult patients with unipolar depression compared to usual care: A randomized controlled trial

BACKGROUND

Patients with depression often have limited access to outpatient psychotherapy following inpatient treatment. The objective of the study was to evaluate the long-term effectiveness of a telephone-based aftercare case management (ACM) intervention for patients with depression.

METHODS

We performed a prospective randomized controlled trial in four psychotherapeutic inpatient care units with N = 199 patients with major depression or dysthymia (F32.x, F33.x, F34.1, according to the ICD-10). The ACM consisted of six phone contacts at two-week intervals performed by trained and certified psychotherapists. The control group received usual care (UC). The primary outcome was depressive symptom severity (BDI-II) at 9-month follow-up, and secondary outcomes were health-related quality of life (SF-8, EQ-5D), self-efficacy (SWE), and the proportion of patients initiating outpatient psychotherapy. Mixed model analyses were conducted to compare improvements between treatment groups.

RESULTS

Regarding the primary outcome of symptom severity, the groups did not significantly differ after 3 months (p = .132; ES = -0.23) or at the 9-month follow-up (p = .284; ES = -0.20). No significant differences in health-related quality of life or self-efficacy were found between groups. Patients receiving ACM were more likely to be in outpatient psychotherapy after 3 months (OR: 3.00[1.12-8.07]; p = .029) and 9 months (OR: 4.78 [1.55-14.74]; p = .006) than those receiving UC.

CONCLUSIONS

Although telephone-based ACM did not significantly improve symptom severity, it seems to be a valuable approach for overcoming treatment barriers to the clinical pathways of patients with depression regarding their access to outpatient psychotherapy.

Predicting the preferences for involvement in medical decision making among patients with mental disorders

BACKGROUND

The involvement of patients in medical decision making has been investigated widely in somatic diseases. However, little is known about the preferences for involvement and variables that could predict these preferences in patients with mental disorders.

OBJECTIVE

This study aims to determine what roles mentally ill patients actually want to assume when making medical decisions and to identify the variables that could predict this role, including patients' self-efficacy.

METHOD

Demographic and clinical data of 798 patients with mental disorders from three psychotherapeutic units in Germany were elicited using self-report questionnaires. Control preference was measured using the Control Preferences Scale, and patients' perceived self-efficacy was assessed using the Self-Efficacy Scale. Bivariate and multivariate regression analyses were conducted to investigate the associations between patient variables and control preference.

RESULTS

Most patients preferred a collaborative role (57.5%), followed by a semi passive (21.2%), a partly autonomous (16.2%), an autonomous (2.8%) and a fully passive (2.3%) role when making medical decisions. Age, sex, diagnosis, employment status, medical pretreatment and perceived self-efficacy were associated with the preference for involvement in the multivariate logistic model.

CONCLUSION

Our results confirm the preferences for involvement in medical decisions of mentally ill patients. We reconfirmed previous findings that older patients prefer a shared role over an autonomous role and that subjects with a high qualification prefer a more autonomous role over a shared role. The knowledge about predictors may help strengthen treatment effectiveness because matching the preferred and actual role preferences has been shown to improve clinical outcome.

Effectiveness of case management as a cross-sectoral healthcare provision for women with breast cancer

OBJECTIVE

Case management (CM) programs are intended to improve care coordination for cancer patients. This quasi-experimental, controlled study evaluated whether such a program was effective in improving health-related quality of life and reducing the psychological distress of breast cancer patients.

METHODS

For the study, 126 patients with CM and 118 patients with treatment as usual (TAU) were surveyed at baseline, a 6-month follow-up and a 12-month follow-up. Comparisons of the two groups with regard to quality of life (Short Form-8, European Organization for Research and Treatment of Cancer-11; primary outcome) and psychological distress (Hospital Anxiety and Depression Scale, distress thermometer; secondary outcome) were conducted.

RESULTS

Univariate t-tests regarding the primary and secondary outcomes demonstrated improvements in the relevant outcomes at the 6-month and 12-month follow-ups for the intervention group as well as for the control group. An analysis of covariance revealed that the controls showed a higher level of physical quality of life at the 12-month follow-up than the other time points and no differences at 6 months after the baseline.

CONCLUSIONS

The tested CM model did not improve the quality of life or psychological well-being of the patients beyond treatment as usual. Possible reasons include that the treatment was already of high standards in the control group or that there are possibly different impacts than found in the literature regarding different forms of organization in CM. The need for and the tailoring of this CM model as well as the transfer of CM to other oncological indications remain to be clarified. Copyright © 2016 John Wiley & Sons, Ltd.

Symptom change trajectories during inpatient psychotherapy in routine care and their associations with long-term outcomes

This study examined symptom change trajectories during inpatient psychotherapy and the association of these changes with long-term outcomes. In an observational multicenter study, weekly measurements of symptom severity were performed during inpatient treatment and 6 months after discharge. The symptom severity was measured using the 18-item scale of the Hamburg Modules for the Assessment of Psychosocial Health. The sample included 576 inpatients (mean age: 43.9 years; 77.6% female; main diagnoses: depressive (57.2%), adjustment (15.8%), anxiety (7.4%), and eating disorders (7.2%); mean treatment duration: 42.0 days). With empirically and clinically informed growth mixture models four subgroups of symptom change were revealed: gradual response (71%), early response (9%), delayed response (5%), and nonresponse (11%). Particularly low educational level, non-employment and chronic disorders were associated with unfavorable symptom courses (non- and delayed response). Long-term outcomes differed systematically across subgroups (p<0.001; η(2)=0.165). The patients who responded early presented the highest rates of clinically significant improvement (43.9%) from admission to follow-up. Nearly all of these patients (92.7%) showed reliable improvement. Due to the high association of symptom change trajectories with long-term outcomes, results may contribute to interventions that are tailored to the needs of patients and may foster longer lasting therapeutic effectiveness.

[Collaborative and stepped care for depression: Development of a model project within the Hamburg Network for Mental Health (psychenet.de)]

BACKGROUND

Depression is one of the most widespread mental disorders in Germany and causes a great suffering and involves high costs. Guidelines recommend stepped and interdisciplinary collaborative care models for the treatment of depression.

OBJECTIVES

Stepped and collaborative care models are described regarding their efficacy and cost-effectiveness. A current model project within the Hamburg Network for Mental Health exemplifies how guideline-based stepped diagnostics and treatment incorporating innovative low-intensity interventions are implemented by a large network of health care professionals and clinics.

MATERIALS AND METHODS

An accompanying evaluation using a cluster randomized controlled design assesses depressive symptom reduction and cost-effectiveness for patients treated within "Health Network Depression" ("Gesundheitsnetz Depression", a subproject of psychenet.de) compared with patients treated in routine care.

RESULTS

Over 90 partners from inpatient and outpatient treatment have been successfully involved in recruiting over 600 patients within the stepped care model. Communication in the network was greatly facilitated by the use of an innovative online tool for the supply and reservation of treatment capacities. The participating professionals profit from the improved infrastructure and the implementation of advanced training and quality circle work.

CONCLUSIONS

New treatment models can greatly improve the treatment of depression owing to their explicit reference to guidelines, the establishment of algorithms for diagnostics and treatment, the integration of practices and clinics, in addition to the implementation of low-intensity treatment alternatives. These models could promote the development of a disease management program for depression.

[psychenet - The Hamburg Network for Mental Health: Evaluation of the Health Network Depression from the Perspective of Participating General Practitioners, Psychotherapists and Psychiatrists]

OBJECTIVE

Evaluation of satisfaction and acceptance of a stepped care model in the Health Network Depression from the perspective of general practitioners, psychotherapists and psychiatrists.

METHODS

Cross-sectional questionnaire study with n = 61 care providers.

RESULTS

All elements of the stepped care model, e. g. screening, diagnostic, and monitoring checklists, guidelines, low-intensity treatment options and IT-tools were utilized by over 75 % of partners and obtained largely positive ratings.

CONCLUSION

This positive evaluation provides a basis for further participative development and transfer into health care.

Cost-effectiveness of collaborative care for the treatment of depressive disorders in primary care: a systematic review

BACKGROUND

For the treatment of depressive disorders, the framework of collaborative care has been recommended, which showed improved outcomes in the primary care sector. Yet, an earlier literature review did not find sufficient evidence to draw robust conclusions on the cost-effectiveness of collaborative care.

PURPOSE

To systematically review studies on the cost-effectiveness of collaborative care, compared with usual care for the treatment of patients with depressive disorders in primary care.

METHODS

A systematic literature search in major databases was conducted. Risk of bias was assessed using the Cochrane Collaboration's tool. Methodological quality of the articles was assessed using the Consensus on Health Economic Criteria (CHEC) list. To ensure comparability across studies, cost data were inflated to the year 2012 using country-specific gross domestic product inflation rates, and were adjusted to international dollars using purchasing power parities (PPP).

RESULTS

In total, 19 cost-effectiveness analyses were reviewed. The included studies had sample sizes between n = 65 to n = 1,801, and time horizons between six to 24 months. Between 42% and 89% of the CHEC quality criteria were fulfilled, and in only one study no risk of bias was identified. A societal perspective was used by five studies. Incremental costs per depression-free day ranged from dominance to US$PPP 64.89, and incremental costs per QALY from dominance to US$PPP 874,562.

CONCLUSION

Despite our review improved the comparability of study results, cost-effectiveness of collaborative care compared with usual care for the treatment of patients with depressive disorders in primary care is ambiguous depending on willingness to pay. A still considerable uncertainty, due to inconsistent methodological quality and results among included studies, suggests further cost-effectiveness analyses using QALYs as effect measures and a time horizon of at least 1 year.

Effectiveness of case management-based aftercare coordination by phone for patients with depressive and anxiety disorders: study protocol for a randomized controlled trial

BACKGROUND

Depressive and anxiety disorders are highly prevalent, but only a small percentage (approximately 50%) of patients receive appropriate treatment. Relevant barriers include communication and coordination gaps between different providers that result from the lack of integration between different care-giving systems. Aftercare following inpatient treatment represents one of these gaps because systematic follow-up care does not exist. Case management-based aftercare coordination by phone might be a promising approach to overcoming this gap and improving long-term treatment outcomes. Case management is a patient-centered and situation-based approach comprising systematic tracking and support of patients by a case manager. The aim of this study is to evaluate the effectiveness of aftercare coordination by phone for patients with depressive and anxiety disorders.

METHODS/DESIGN

The effectiveness of aftercare coordination will be investigated in a prospective randomized controlled trial in four psychotherapeutic inpatient routine care units (St. Franziska-Stift Bad Kreuznach, MediClin Seepark Klinik Bad Bodenteich, Segeberger Kliniken Gruppe Bad Segeberg and Luisenklinik Bad Dürrheim). The patients receiving aftercare coordination (intervention group; IG) will be compared with those who receive treatment as usual (TAU control group; CG). Eligible patients will be required to have a diagnosis of an anxiety and/or depressive disorder and a recommendation for follow-up outpatient psychotherapy. The aftercare coordination consists of six phone contacts at intervals of two weeks that are performed by therapists in the inpatient units. The patients will complete questionnaires at discharge (t1), 3 months after discharge (i.e., at the end of the intervention (t2)) and 9 months after discharge (t3). The primary outcome will be change in symptom severity from t1 to t3, the secondary outcomes will be health-related quality of life and the proportion of patients who manage to begin outpatient psychotherapy by t3.

DISCUSSION

This study will determine whether case management-based aftercare coordination by phone is an adequate approach for overcoming treatment barriers in the clinical pathways of patients with depressive and anxiety disorders. If proven effective, an accessible supplementary treatment approach that will help to maintain and even improve long-term treatment outcomes will be made available for patients following inpatient treatment.

[Health care barriers on the pathways of patients with anxiety and depressive disorders - a qualitative interview study]

OBJECTIVE

Which health care barriers do patients with anxiety and depressive disorders experience on their clinical pathways?

METHODS

Semi-structured interviews were conducted among 30 patients with anxiety and depressive disorders. Interviews were audio-taped, transcribed, coded and content-analysed.

RESULTS

Following barriers perceived by patients were extracted: a lack of early diagnosis, communication and coordination problems between different services and providers, little information about their illness and its adequate treatment, as well as intrapersonal barriers.

CONCLUSIONS

Patients perceive barriers on the individual, provider and system level. Especially barriers on the system and provider level indicate a need for more information, early recognition and support especially during the help-seeking process.

Effectiveness and cost-effectiveness of a guideline-based stepped care model for patients with depression: study protocol of a cluster-randomized controlled trial in routine care

BACKGROUND

Depression is a widespread and serious disease often accompanied by a high degree of suffering and burden of disease. The lack of integration between different care providers impedes guideline-based treatment. This constitutes substantial challenges for the health care system and also causes considerable direct and indirect costs. To face these challenges, the aim of this project is the implementation and evaluation of a guideline-based stepped care model for depressed patients with six treatment options of varying intensity and setting, including low-intensity treatments using innovative technologies.

METHODS/DESIGN

The study is a randomized controlled intervention trial of a consecutive sample of depressive patients from primary care assessed with a prospective survey at four time-standardized measurement points within one year. A cluster randomization at the level of participating primary care units divides the general practitioners into two groups. In the intervention group patients (n = 660) are treated within the stepped care approach in a multiprofessional network consisting of general practitioners, psychotherapists, psychiatrists and inpatient care facilities, whereas patients in the control condition (n = 200) receive routine care. The main research question concerns the effectiveness of the stepped-care model from baseline to t3 (12 months). Primary outcome is the change in depressive symptoms measured by the PHQ-9; secondary outcomes include response, remission and relapse, functional quality of life (SF-12 and EQ-5D-3 L), other clinical and psychosocial variables, direct and indirect costs, and the incremental cost-effectiveness ratio. Furthermore feasibility and acceptance of the overall model as well as of the separate treatment components are assessed.

DISCUSSION

This stepped care model integrates all primary and secondary health care providers involved in the treatment of depression; it elaborates innovative and evidence-based treatment elements, follows a stratified approach and is implemented in routine care as opposed to standardized conditions. In case of positive results, its sustainable implementation as a collaborative care model may significantly improve the health care situation of depressive patients as well as the interaction and care delivery of different care providers on various levels.

TRIAL REGISTRATION

This study is registered with ClinicalTrials.gov, number NCT01731717 (date of registration: 24 June 2013).

[Data analysis based on the Classification of Therapeutic Procedures (CTL) of inpatient rehabilitation of depressive disorders]

OBJECTIVE

As an initiative of the German Pension Insurance Association (DRV), evidence-based therapeutic modules (ETM) for the rehabilitation of patients with depression were developed. The objective of the subsequent analysis was to analyse the therapeutic procedures in inpatient rehabilitation on the basis of the ETM to evaluate the principal needs for therapeutic standards.

METHODS

Data based on the German Classification of Therapeutic Procedures (KTL) for 21 529 patients treated in rehabilitation clinics for people with mental illnesses was analysed with respect to differences between diagnostic groups/clinics regarding type, quantity and duration of measures coded.

RESULTS

The mean quantity and duration of the interventions for patients with depressive disorders encoded varied greatly between the ETM. No or only minor differences were found between patients with depression and those with other diagnoses regarding the type, quantity and duration of measures coded. However, there were great variances between clinics.

CONCLUSIONS

Therapeutic standards for rehabilitative practice appear necessary in order to reduce treatment heterogeneity between rehabilitation facilities, which could improve the quality of healthcare.

Rationale and content of psychenet: the Hamburg Network for Mental Health

With the public-funded research and development project psychenet: the Hamburg Network for Mental Health (2011-2014), the Federal Ministry of Education and Research contributes to strengthening healthcare regions in Germany by establishing new trans-sectoral cooperations and implement and evaluate selected innovations. More than 60 partners from research, health care, health industry and government in the Free and Hanseatic City of Hamburg are promoting innovative measures to improve the treatment for mental disorders. The main objective is to implement integrated healthcare networks based on evidence for effective treatment methods, deriving from high-quality research throughout five indications such as psychosis, depression, somatoform and functional syndromes, anorexia and bulimia and addiction illnesses in adolescence. Those networks are accompanied by additional measures, for example, for improving information and education, addressing occupational health or strengthening the participation of patients and their families suffering from mental illness.

Non-pharmacological treatment of depressive disorders: a review of evidence-based treatment options

BACKGROUND

The primary goals of this paper are to describe the collection and evaluation of various nonpharmacological treatment options for depressive disorders and to establish a basis for the development of a standard for the treatment of patients with depressive disorders.

METHOD

To identify evidence-based treatment elements, a comprehensive investigation of national and international guidelines was conducted. The extracted guidelines were then assessed with regard to aspects of methodological quality and evidence-based treatment elements. In a further step, specific and systematic literature searches for residual treatment elements were conducted. For the corresponding literature search, a hierarchical approach was chosen in which current guidelines were reviewed first and systematic reviews and meta-analyses second. Psychopharmacological treatments were excluded from the analysis because this is covered by specific guidelines.

RESULTS

The treatment elements with an adequate level of evidence were identified as follows: psychotherapeutic interventions, marital/couples/family therapy and counseling, inclusion of family members, psycho-education, exercise, problem solving therapy, guided self-help and behavioral activation treatments. Further evidence-based methods include diagnostic treatment elements, participative decision-making, development of the therapeutic alliance, Cognitive Behavioral Analysis System for Psychotherapy, computerized cognitive behavior therapy, psychopharmacological therapy, combined psychopharmacological and psychotherapeutic therapy, electroconvulsive therapy, phototherapy, sleep deprivation, repetitive trans-cranial magnetic stimulation (rTMS) and acupuncture.

CONCLUSION

In summary, using a hierarchical approach, it was possible to assign different levels of evidence to the various treatment options for depression.

Self-efficacy and fear of cancer progression during the year following diagnosis of breast cancer

OBJECTIVE

The aim of this study was to investigate fear of disease progression (FoP) during the year following diagnosis of breast cancer and its association with general self-efficacy (SE).

METHODS

In a prospective study, 118 breast cancer patients were recruited shortly after diagnosis disclosure (response rate: 54%) and at 1-year follow-up (follow-up rate: 90%). Participants completed self-report measures of general self-efficacy (General Self-Efficacy Scale) and fear of progression (short form of the Fear of Progression Questionnaire).

RESULTS

Cross-sectional regression analysis revealed that high FoP is significantly associated with low SE, even when controlling for demographic and medical characteristics (total R² = 0.17). Having children and a relatively short time since diagnosis also significantly predicted higher FoP. Longitudinal analyses showed that FoP decreased significantly over time (p = 0.001; d = 0.25), but a significant decrease was only observed for patients with high initial FoP (p < 0.001; d = 0.74) and not for those with low initial FoP (p = 0.688; d = 0.08). SE was not a significant predictor of FoP at follow-up when controlling for initial FoP and other patient characteristics (incremental R² = 0.001; p = 0.674; total R² = 0.47). Overall, only initial FoP significantly predicted FoP at follow-up (p < 0.001; β = 0.671).

CONCLUSION

Findings that low SE is associated with high FoP can help to improve the treatment of dysfunctional fears in breast cancer patients. As FoP changes only slightly over time, treatment to enhance SE and reduce FoP should be initiated soon after disease disclosure.

Effectiveness of systematic treatment selection for psychodynamic and cognitive-behavioural therapy: randomised controlled trial in routine mental healthcare

BACKGROUND

Although cognitive-behavioural therapy (CBT) and psychodynamic therapy (PDT) are both effective treatments for mental disorders, they show clear dissimilarities concerning their therapeutic models and treatment rationales.

AIMS

To determine the effectiveness of systematic treatment selection (STS) to CBT or PDT in a mental healthcare setting compared with a control procedure of random treatment selection (RTS).

METHOD

A randomised controlled trial in a consecutive sample of 291 in-patients with at least one ICD-10 mental disorder was performed. The primary outcome was symptom severity (General Severity Index of the Symptom Checklist-14) at 6-month follow-up. Health-related quality of life was the secondary outcome, determined using the Short Form-8.

RESULTS

Analyses revealed no general effect for systematic treatment selection. However, there was a differential effect: systematic selection resulted in a better longer-term outcome for PDT, but not for CBT; STS-PDT patients showed a significantly larger reduction in symptom severity than RTS-PDT patients. This difference was not observed in CBT.

CONCLUSIONS

Since systematic treatment selection seems to be able to optimise treatment outcome, at least for PDT, pursuing systematic treatment assignment strategies in mental healthcare settings is a worthwhile endeavour.

Diabetes in primary care: prospective associations between depression, nonadherence and glycemic control

BACKGROUND

Findings are inconsistent regarding the degree to which depression may exert a negative impact on glycemic control in patients with type 2 diabetes. We therefore aimed to examine the longitudinal relationship between depression, behavioral factors, and glycemic control.

METHODS

In a prospective component of a nationally representative sample, 866 patients with type 2 diabetes aged >or=18 years completed a standardized assessment including a laboratory screening, questionnaires, and diagnostic measures. Subsequent to baseline (t(0)), patients were tracked over a period of 12 months (t(1)). Depression was assessed according to DSM-IV and ICD-10 criteria. Glycemic control was determined by levels of glycosylated hemoglobin (HbA(1c)); a level of >or=7% was judged as unsatisfactory. Regression analyses were performed to analyze the prospective relationship between depression, medication adherence, diabetes-related health behavior, and HbA(1c).

RESULTS

Patients with depression at t(0) revealed increased rates of medication nonadherence (adjusted OR: 2.67; CI: 1.38-5.15) at t(1). Depression (adjusted regression coefficient: beta = 0.96; p = 0.001) and subthreshold depression (beta = 1.01; p < 0.001) at t(0) also predicted increased problems with diabetes-related health behavior at t(1). Adjusted ORs for poor glycemic control (HbA(1c) >or=7%) at t(1) were also increased for patients with baseline depression (2.01; CI: 1.10-3.69). However, problems with medication adherence as well as problems with diabetes-related health behavior at t(0) did not predict poor glycemic control at t(1).

CONCLUSIONS

In a prospective representative study of patients with type 2 diabetes, baseline depression predicted problems with medication adherence, problems with health-related behaviors, and unsatisfactory glycemic control at follow-up.

[Evidence-based treatments in the rehabilitation of patients with depression--a literature review]

BACKGROUND

In recent years, the importance of guidelines has increased continuously. This development also occurs in the field of rehabilitative health care, where process guidelines are being designed for various indicational groups to ensure quality standards and improvements.

AIM

The primary goal of this paper is to collect and evaluate the evidence for various treatment options for depressive disorders in order to establish a basis for the current development of a process guideline for the rehabilitation of patients with depressive disorders.

METHOD

In order to identify evidence based treatment elements, first a comprehensive investigation of national and international guidelines was conducted. Thirteen selected guidelines were then assessed with regard to aspects of methodological quality and evidence-based treatment elements. In a further step, literature searches were conducted for residual treatment elements, which were identified on the basis of the Classification of Therapeutic Services (KTL) 2007. For the literature search, a hierarchical approach was chosen: At first, meta-analyses and systematic reviews were viewed. In case when there was still a lack of evidence for specific, potentially relevant treatment elements, the search was expanded to the level of primary studies. All selected reviews and primary studies then underwent a standardized assessment especially regarding methodological quality and evidence grades were allocated to treatments.

RESULTS

Thereby, the following treatment elements with an adequate level of evidence were identified: Psychotherapeutic interventions, marital/couples/family therapy and counselling, inclusion of family members, psycho education and exercise, problem solving therapy, guided self-help, and behavioural activation treatments. On the basis of this complementary literature search, various other evident interventions could be identified within the following areas: relaxation techniques, improvement of social competence, occupational therapy, art therapies (music, movement/dance therapies), body-oriented therapies and massage therapy.

CONCLUSION

In summary, using this hierarchical approach, it was possible to assign different levels of evidence to the various treatment elements for depression. Based on the results of this literature search, a next step in the development of a process guideline for the rehabilitative treatment of patients with depression will be the integration of experts in the field of rehabilitation.

Comparison of therapeutic action, style and content in cognitive-behavioural and psychodynamic group therapy under clinically representative conditions

It is still an open question whether psychotherapists adhere to their therapeutic conceptions in routine practice (clinician's treatment adherence) and thus to what extent the two most common approaches, cognitive-behavioural (CBT) and psychodynamic therapy (PDT), differ from each other as theoretically expected (treatment differentiation). This holds true especially in case of group therapy.The study compares essential process components of CBT and PDT group treatments under clinically representative conditions using non-participating observer ratings. Results demonstrate that CBT group therapists use more cognitive, behavioural and psychoeducational strategies, foster self-efficacy to a larger extent and are more supporting and empathetic. PDT group therapists use more interpretative and confrontative interventions and focus on interactional and dynamic aspects. The results strongly support that not only in individual psychotherapy-as shown in prior research-but also in the group setting do CBT and PDT reveal very distinct profiles and that therapists primarily abide by their theoretical training also in clinical practice. They allow one to identify differential process components of the group setting and to trace back parameters of outcome to the process of CBT and PDT for clinical routines.

[Which integrative and disorder specific treatment approaches are considered in research papers? An analysis on psychotherapeutic treatments in German journals]

In the current discussion on optimizing psychotherapeutic approaches, two important developments have to be considered: a tendency towards integrative and a tendency towards disorder specific approaches. For the years 2005 and 2006, an analysis of three German journals (covering the fields of psychosomatics, psychiatry and clinical psychology) was conducted on the question whether these two developments can be identified in current empirical and conceptual publications. Contrary to the expectations, there are only very few papers dealing with integrative approaches. As expected, there is a major emphasis on psychodynamic and cognitive behavioural approaches; other approaches are only marginally considered. A disorder specific approach can be identified not only for cognitive behavioural, but also for psychodynamic papers.

[On the theoretical and empirical differences of therapeutic interventions, contents, and styles between cognitive behavioural and psychodynamic psychotherapies]

Since cognitive behavioural (CBT) and psychodynamic (PDT) approaches treat patients with comparable disorder spectrums, yet at the same time show very different fundamental concepts, training modalities and treatment rationale, a comparison of the process and outcome of these methods becomes particularly significant. The present article offers an overview of the significance of comparative process research as well as of the theoretical and, in particular, the empirical knowledge concerning the difference between CBT and PDT at the process level (therapeutic interventions, contents and styles). Results show that CBT and PDT display pronounced differences in a broader spectrum of process variables not only on the basis of their theoretical conceptions but also referring to empirical data. While at least within the framework of experimental designs the general result of different profiles can be considered robust, statements concerning the actual treatment practice and clinical routines can only be made on a very isolated basis due to a lack of naturalistic studies. The need for research which can be derived from this, as well as further necessary developments in the field of comparative process research are discussed.
