Nonpharmacologic and Pharmacologic Treatments of Adult Patients With Major Depressive Disorder: A Systematic Review and Network Meta-analysis for a Clinical Guideline by the American College of Physicians.

BACKGROUND: Primary care patients and clinicians may prefer alternative options to second-generation antidepressants for major depressive disorder (MDD). PURPOSE: To compare the benefits and harms of nonpharmacologic treatments with second-generation antidepressants as first-step interventions for acute MDD, and to compare second-step treatment strategies for patients who did not achieve remission after an initial attempt with antidepressants. DATA SOURCES: English-language studies from several electronic databases from 1 January 1990 to 8 August 2022, trial registries, gray literature databases, and reference lists to identify unpublished research. STUDY SELECTION: 2 investigators independently selected randomized trials of at least 6 weeks' duration. DATA EXTRACTION: Reviewers abstracted data about study design and conduct, participants, interventions, and outcomes. They dually rated the risk of bias of studies and the certainty of evidence for outcomes of interest. DATA SYNTHESIS: 65 randomized trials met the inclusion criteria; eligible data from nonrandomized studies were not found. Meta-analyses and network meta-analyses indicated similar benefits of most nonpharmacologic treatments and antidepressants as first-step treatments. Antidepressants had higher risks for discontinuation because of adverse events than most other treatments. For second-step therapies, different switching and augmentation strategies provided similar symptomatic relief. The certainty of evidence for most comparisons is low; findings should be interpreted cautiously. LIMITATIONS: Many studies had methodological limitations or dosing inequalities; publication bias might have affected some comparisons. In some cases, conclusions could not be drawn because of insufficient evidence. CONCLUSION: Although benefits seem to be similar among first- and second-step MDD treatments, the certainty of evidence is low for most comparisons. Clinicians and patients should focus on options with the most reliable evidence and take adverse event profiles and patient preferences into consideration.

Education level and COVID-19 vaccination willingness in adolescents.

Vaccination is essential to control the COVID-19 pandemic. High vaccination willingness is a key for successful vaccination programs. This study assessed attitudes toward vaccination in Austrian adolescents and determined whether there are differences in vaccination readiness regarding education status, gender and migration background. Two cross-sectional online surveys were conducted from March to July 2021 in apprentices and high school students. Willingness to receive COVID-19 vaccination was rated on a 5-point scale. In total, n = 2006 (n = 1442 apprentices and n = 564 high school students) completed the survey. Willingness to receive COVID-19 vaccination was higher in students compared to apprentices (p < 0.001). Furthermore, migration background (p = 0.023) and female gender (p = 0.001) were associated with lower vaccination willingness. In conclusion, more efforts are required to improve confidence and willingness to vaccinate adolescents with lower educational levels, those with migrant backgrounds and females.

Mental health burden of high school students, and suggestions for psychosocial support, 1.5 years into the COVID-19 pandemic in Austria.

The COVID-19 pandemic and containment efforts seem to be particularly challenging for adolescents. This study assessed mental health in high school students 1.5 years after the pandemic began in Austria. A cross-sectional survey was carried out from September to November 2021. Well-being (WHO-5), depressive symptoms, anxiety symptoms and sleep quality were assessed. A total of 1505 adolescents participated (78% girls). The cut-offs for clinically relevant symptoms were exceeded by 62% girls and 38.1% boys for depression (PHQ-9 score ≥ 11), 49% girls and 29% boys for anxiety (GAD-7 score ≥ 11) and 28% girls and 17% boys for insomnia (ISI score ≥ 15). The prevalence of suicidal ideation (item 9 of the PHQ-9) within the last 2 weeks was 47% in girls and 32% in boys. These data collected in autumn 2021 (the start of the second semester of reopened schools; t2) were compared to data collected in February 2021 (one semester after remote schooling; t1). A matched pairs analysis according to age, gender, region, school type and migration background resulted in a total sample size of N = 2514 adolescents. Results showed small deteriorations in mental health (i.e., well-being, depression, insomnia, suicidal ideation) in girls at t2 compared to t1, and an increase in suicidal thoughts in boys (all p-values < 0.05). Qualitative data show that young people have a need for more psychological support, both professional and informal, as well as increased mental health literacy. Results suggest that mental health burden in adolescents remains high 1.5 years into the pandemic and highlight the need to implement timely psychological support.

Stress levels in high-school students after a semester of home-schooling.

There has been an increase in stress in adolescents since the beginning of the COVID-19 pandemic. Social distancing and home-schooling are just two of many stress factors for this age group. The aim of this study was to assess stress in high-school students after a semester of home-schooling. A cross-sectional online survey (February 3rd to 28th 2021) was performed, measuring stress with the Perceived Stress Scale (PSS-10) in Austria. In total, N = 2884 students (age: M = 16.47 (SD = 1.44); 70.4% females) completed the survey. Mean PSS-10 score was M = 23.50 (SD = 7.47) [females: M = 24.69 (SD = 6.80); males: M = 20.11 (SD = 7.93); p < 0.001]. 11.0% reported low stress (females: 7.2%; males 20.9%), 52.5% moderate stress (females: 51.5%; males: 57.3%), and 36.5% high stress (females: 41.3%; males 21.8%); p < 0.001. Around one-third of high-school students suffer from high stress level, females almost twice as often as males. Psychological support should particularly focus on stress and possibilities to reduce it.

Mental Health During COVID-19 Lockdown in the United Kingdom.

OBJECTIVE: The coronavirus disease (COVID-19) pandemic and related lockdown measures have raised important questions about the impact on mental health. This study evaluated several mental health and well-being indicators in a large sample from the United Kingdom (UK) during the COVID-19 lockdown where the death rate is currently among the highest in Europe. METHODS: A cross-sectional online survey with a study sample that mirrors general population norms according to sex, age, education, and region was launched 4 weeks after lockdown measures were implemented in the UK. Measures included mental health-related quality of life (World Health Organization Quality-of-Life Brief Version psychological domain), well-being (World Health Organization Well-Being Index), depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7), perceived stress (Perceived Stress Scale-10), and insomnia (Insomnia Severity Index). Analyses of variances, Bonferroni-corrected post hoc tests, and t tests were applied to examine mental health indicators across different sociodemographic groups (age, sex, employment, income, physical activity, relationship status). RESULTS: The sample comprised n = 1006 respondents (54% women) from all regions of the UK. Approximately 52% of respondents screened positive for a common mental disorder, and 28% screened positive for clinical insomnia. Mean scores and standard deviations were as follows: Patient Health Questionnaire-9, mean = 9.0 ± 7.7; Generalized Anxiety Disorder-7, mean = 8.0 ± 6.5; Insomnia Severity Index, mean = 10.4 ± 7.0; Perceived Stress Scale-10, mean = 17.7 ± 7.9; World Health Organization Quality-of-Life Brief Version, mean = 58.6 ± 21.4; and World Health Organization Well-Being Index score, mean = 13.0 ± 6.0. Statistical analyses consistently indicated more severe mental health problems in adults younger than 35 years, women, people with no work, and people with low income (all p values < .05). Mental health indices also varied across UK regions. CONCLUSIONS: The prevalence of depressive, anxiety, and insomnia symptoms is significantly higher in the UK relative to prepandemic epidemiological data. Further studies are needed to clarify the causes for these high rates of mental health symptoms.

Therapeutic interventions in in-person and remote psychotherapy: Survey with psychotherapists and patients experiencing in-person and remote psychotherapy during COVID-19.

OBJECTIVE: First, to investigate how psychotherapists and patients experience the change from in-person to remote psychotherapy or vice versa during COVID-19 regarding the therapeutic interventions used. Second, to explore the influence of therapeutic orientations on therapeutic interventions in in-person versus remote psychotherapy. METHOD: Psychotherapists (N = 217) from Austria were recruited, who in turn recruited their patients (N = 133). The therapeutic orientation of the therapists was psychodynamic (22.6%), humanistic (46.1%), systemic (20.7%) or behavioural (10.6%). All the data were collected remotely via online surveys. Therapists and patients completed two versions of the 'Multitheoretical List of Therapeutic Interventions' (MULTI-30) (version 1: in-person; version 2: remote) to investigate differences between in-person and remote psychotherapy in the following therapeutic interventions: psychodynamic, common factors, person-centred, process-experiential, interpersonal, cognitive, behavioural and dialectical-behavioural. RESULTS: Therapists rated all examined therapeutic interventions as more typical for in-person than for remote psychotherapy. For patients, three therapeutic interventions (psychodynamic, process-experiential, cognitive interventions) were more typical for in-person than for remote psychotherapy after correcting for multiple testing. For two therapeutic interventions (behavioural, dialectical-behavioural), differences between the four therapeutic orientations were more consistent for in-person than for remote psychotherapy. CONCLUSIONS: Therapeutic interventions differed between in-person and remote psychotherapy and differences between therapeutic orientations in behavioural-oriented interventions become indistinct in remote psychotherapy.

Effects of alliance ruptures and repairs on outcomes.

This study explored whether treatment outcomes in a trial on the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) vs. Supportive Psychotherapy (SP) for patients with early-onset chronic depression differ between alliance patterns.Session-to-session ratings of the therapeutic alliance (Helping Alliance Questionnaire (HAQ)) from 254 outpatients with chronic depression (CBASP: 134; SP: 120) who took part in a multicenter randomized controlled trial of CBASP vs. SP were used to categorize patients into three alliance pattern categories for the patients' and therapists' rating separately. Based on the reliable change in the HAQ from one session to the next categories were: no rupture, unrepaired rupture, rupture-repair. Depression severity (24-item Hamilton Rating Scale for Depression) at post-treatment, at 12- and 24- months follow-up was the outcome.The alliance pattern categories for therapists and patients did not differ between CBASP and SP. Only the alliance patterns calculated for patients were associated with outcome: in the unrepaired rupture category, patients had higher HRSD-ratings across time points (p = 0.047).CBASP was not associated with more or fewer ruptures or repairs as compared to SP in the treatment of chronic depression. The study highlights the need to resolve ruptures to avoid poor outcomes.Trial registration: ClinicalTrials.gov identifier: NCT00970437.

Stress, depression, and the therapeutic alliance as mediators on the outcome of brief psychodynamic-interpersonal psychotherapy for multisomatoform disorder.

The aim of this study was to identify and explore mediators of psychodynamic-interpersonal psychotherapy (PIT) on treatment outcome in multisomatoform disorders (MSD).Data from 164 patients with MSD who took part in a randomized control trial of PIT (n = 88) vs. enhanced medical care (EMC; n = 76) were re-analyzed. A parallel mediation analysis was performed to investigate whether the beneficial effect of PIT vs. EMC on physical quality of life (physical component summary (PCS) of the SF-36 Health Survey) nine months post-treatment is mediated by post-treatment scores of stress, depression, and therapeutic alliance. The potential mediators were operationalized with the Helping Alliance Questionnaire (HAQ; therapeutic alliance), the Patient Health Questionnaire (PHQ)-stress module (perceived stress) and the PHQ-depression module (PHQ-9; depression).Stress partially mediated the effect of PIT vs. EMC on the follow-up outcome. PIT (as compared to EMC) led to lower post-treatment stress-levels, which in turn led to higher physical quality of life at follow-up. Neither depression nor the alliance had a mediating effect.Stress mediated the outcome of PIT for MSD. Future studies are needed to extend the scope of research regarding which specific psychotherapeutic mechanisms of change are beneficial in PIT treatment of MSD patients.

Coping strategies and mental health during COVID-19 lockdown.

BACKGROUND: COVID-19 pandemic lockdown measures changed the everyday lives of people around the world. AIMS: To evaluate the effects of different coping strategies on mental health during COVID-19 lockdown. METHODS: A representative sample for Austria was recruited through Qualtrics® in a period of 4 weeks after the lockdown started. Measurements were coping inventory (SCI), psychological quality of life (WHO-QOL BREF, psychological domain), well-being (WHO-5), depression (PHQ-9), anxiety (GAD-7), stress (PSS-10), and insomnia (ISI). Regression analyses were performed with coping strategies as predictors and mental health measures as dependent variables. RESULTS: The representative sample included N = 1,005 respondents (52.7% women). Positive thinking, active stress coping and social support were found to be positive predictors for psychological life quality, well-being, and negative predictors for perceived stress, depression, anxiety, and insomnia. Alcohol and cigarette consumption was a negative predictor for psychological life quality, and well-being, and a positive predictor for perceived stress, depression, anxiety, and insomnia. Support in faith was a positive predictor for perceived stress, depression, anxiety, and insomnia. CONCLUSIONS: Coping strategies are significant predictors for mental health measures. Education about positive thinking, active coping, and social support could be beneficial for dealing with a decrease in mental health due to COVID-19 pandemic.

Experiences of Psychotherapists With Remote Psychotherapy During the COVID-19 Pandemic: Cross-sectional Web-Based Survey Study.

BACKGROUND: The current situation around the COVID-19 pandemic and the measures necessary to fight it are creating challenges for psychotherapists, who usually treat patients face-to-face with personal contact. The pandemic is accelerating the use of remote psychotherapy (ie, psychotherapy provided via telephone or the internet). However, some psychotherapists have expressed reservations regarding remote psychotherapy. As psychotherapists are the individuals who determine the frequency of use of remote psychotherapy, the potential of enabling mental health care during the COVID-19 pandemic in line with the protective measures to fight COVID-19 can be realized only if psychotherapists are willing to use remote psychotherapy. OBJECTIVE: This study aimed to investigate the experiences of psychotherapists with remote psychotherapy in the first weeks of the COVID-19 lockdown in Austria (between March 24 and April 1, 2020). METHODS: Austrian psychotherapists were invited to take part in a web-based survey. The therapeutic orientations of the psychotherapists (behavioral, humanistic, psychodynamic, or systemic), their rating of the comparability of remote psychotherapy (web- or telephone-based) with face-to-face psychotherapy involving personal contact, and potential discrepancies between their actual experiences and previous expectations with remote psychotherapy were assessed. Data from 1162 psychotherapists practicing before and during the COVID-19 lockdown were analyzed. RESULTS: Psychotherapy conducted via telephone or the internet was reported to not be totally comparable to psychotherapy with personal contact (P<.001). Psychodynamic (P=.001) and humanistic (P=.005) therapists reported a higher comparability of telephone-based psychotherapy to in-person psychotherapy than behavioral therapists. Experiences with remote therapy (both web- and telephone-based) were more positive than previously expected (P<.001). Psychodynamic therapists reported more positive experiences with telephone-based psychotherapy than expected compared to behavioral (P=.03) and systemic (P=.002) therapists. In general, web-based psychotherapy was rated more positively (regarding comparability to psychotherapy with personal contact and experiences vs expectations) than telephone-based psychotherapy (P<.001); however, psychodynamic therapists reported their previous expectations to be equal to their actual experiences for both telephone- and web-based psychotherapy. CONCLUSIONS: Psychotherapists found their experiences with remote psychotherapy (ie, web- or telephone-based psychotherapy) to be better than expected but found that this mode was not totally comparable to face-to-face psychotherapy with personal contact. Especially, behavioral therapists were found to rate telephone-based psychotherapy less favorably than therapists with other theoretical backgrounds.

Metabolomics in Sleep, Insomnia and Sleep Apnea.

Sleep-wake disorders are highly prevalent disorders, which can lead to negative effects on cognitive, emotional and interpersonal functioning, and can cause maladaptive metabolic changes. Recent studies support the notion that metabolic processes correlate with sleep. The study of metabolite biomarkers (metabolomics) in a large-scale manner offers unique opportunities to provide insights into the pathology of diseases by revealing alterations in metabolic pathways. This review aims to summarize the status of metabolomic analyses-based knowledge on sleep disorders and to present knowledge in understanding the metabolic role of sleep in psychiatric disorders. Overall, findings suggest that sleep-wake disorders lead to pronounced alterations in specific metabolic pathways, which might contribute to the association of sleep disorders with other psychiatric disorders and medical conditions. These alterations are mainly related to changes in the metabolism of branched-chain amino acids, as well as glucose and lipid metabolism. In insomnia, alterations in branched-chain amino acid and glucose metabolism were shown among studies. In obstructive sleep apnea, biomarkers related to lipid metabolism seem to be of special importance. Future studies are needed to examine severity, subtypes and treatment of sleep-wake disorders in the context of metabolite levels.

Metabolomic Biomarkers in Anxiety Disorders.

Anxiety disorders range among the most prevalent psychiatric disorders and belong to the leading disorders in the study of the total global burden of disease. Anxiety disorders are complex conditions, with not fully understood etiological mechanisms. Numerous factors, including psychological, genetic, biological, and chemical factors, are thought to be involved in their etiology. Although the diagnosis of anxiety disorders is constantly evolving, diagnostic manuals rely on symptom lists, not on objective biomarkers and treatment effects are small to moderate. The underlying biological factors that drive anxiety disorders may be better suited to serve as biomarkers for guiding personalized medicine, as they are objective and can be measured externally. Therefore, the incorporation of novel biomarkers into current clinical methods might help to generate a classification system for anxiety disorders that can be linked to the underlying dysfunctional pathways. The study of metabolites (metabolomics) in a large-scale manner shows potential for disease diagnosis, for stratification of patients in a heterogeneous patient population, for monitoring therapeutic efficacy and disease progression, and for defining therapeutic targets. All of these are important properties for anxiety disorders, which is a multifactorial condition not involving a single-gene mutation. This review summarizes recent investigations on metabolomics studies in anxiety disorders.

Why are some cases not on track? An item analysis of the Assessment for Signal Cases during inpatient psychotherapy.

Within the Routine Outcome Monitoring system "OQ-Analyst," the questionnaire "Assessment for Signal Cases" (ASC) supports therapists in detecting potential reasons for not-on-track trajectories. Factor analysis and a machine learning algorithm (LASSO with 10-fold cross-validation) were applied, and potential predictors of not-on-track classifications were tested using logistic multilevel modeling methods. The factor analysis revealed a shortened (30 items) version of the ASC with good internal consistency (α = 0.72-0.89) and excellent predictive value (area under the curve = 0.98; positive predictive value = 0.95; negative predictive value = 0.94). Item-level analyses showed that interpersonal problems captured by specific ASC items (not feeling able to speak about problems with family members; feeling rejected or betrayed) are the most important predictors of not-on-track trajectories. It should be considered that our results are based on analyses of ASC items only. Our findings need to be replicated in future studies including other potential predictors of not-on-track trajectories (e.g., changes in medication, specific therapeutic techniques, or treatment adherence), which were not measured this study.

General change mechanisms in the early treatment phase and their associations with the outcome of cognitive behavioural therapy in patients with different levels of motivational incongruence.

Early general change mechanisms (GCMs) have been shown to be associated with psychotherapy outcome but it remains unclear which specific patients benefit from which GCM. This study explored whether the patients' characteristic motivational incongruence moderates the effect of GCMs in the early treatment phase on the outcome. Three early GCMs (interpersonal experiences, intrapersonal experiences, and problem actuation) were evaluated after five therapy-preparing sessions by patients and therapists. On the basis of previous work, we assumed that the association between intrapersonal experiences and outcome is moderated by incongruence. A total of 524 patients completing outpatient cognitive behavioural therapy (CBT) were investigated. The patient-reported outcome measure was psychological symptom severity. The patients' motivational incongruence was assessed with the incongruence questionnaire short form at baseline. Results showed that therapists' ratings of all three early GCMs and patients' ratings of early problem actuation were not associated with CBT outcome. By contrast, positive patients' ratings of early interpersonal and early intrapersonal experiences were beneficial for CBT outcome (both p < .05). Only the association between patients' ratings of early intrapersonal experiences and CBT outcome was moderated by incongruence (p < .05). The higher the patients' baseline incongruence was, the more beneficial early intrapersonal experiences in the patients' perspective were for a good outcome. These findings entail that increasing early intrapersonal experiences from the patients' perspective is particularly important in patients with motivational incongruence but working on early interpersonal experiences in the patients' perspective is important in patients with all levels of incongruence to reach a good CBT outcome.

Mentalization and Self-Efficacy as Mediators between Psychological Symptom Severity and Disabilities in Activities and Participation in Psychotherapy Patients.

BACKGROUND: Psychotherapy patients can be more or less disabled by their psychological symptoms. The present study investigated whether mentalization and self-efficacy contribute to the association between psychological symptom severity and disabilities in activities and participation. METHODS: The data of 216 psychotherapy inpatients were examined in a cross-sectional design. Bootstrapping-enhanced mediation analyses were performed to investigate whether self-efficacy and mentalization are mediators between psychological symptom severity and disabilities in activities and participation. The Hamburg Modules for the Assessment of Psychosocial Health-49 were used to measure psychological symptom severity and self-efficacy, mentalization was assessed with the Mentalization Questionnaire, and disabilities in activities and participation were operationalized with the ICF-Mental-A & P questionnaire. RESULTS: Mentalization as well as self-efficacy functioned as mediators between psychological symptom severity and disabilities in activities and participation (p < 0.05). They were equally strong mediators, and both remained significant mediators when statistically controlling for the other mediator (p < 0.05). CONCLUSIONS: Mentalization as well as self-efficacy explain a significant proportion of the relationship between psychological symptom severity and disabilities in activities and participation. Working on mentalizing and self-efficacy might be important mechanisms to reduce disability due to symptoms. The cross-sectional design is a limitation of the study.

Neural correlates of conversion disorder: overview and meta-analysis of neuroimaging studies on motor conversion disorder.

BACKGROUND: Conversion Disorders (CD) are prevalent functional disorders. Although the pathogenesis is still not completely understood, an interaction of genetic, neurobiological, and psychosocial factors is quite likely. The aim of this study is to provide a systematic overview on imaging studies on CDs and investigate neuronal areas involved in Motor Conversion Disorders (MCD). METHODS: A systematic literature search was conducted on CD. Subsequently a meta-analysis of functional neuroimaging studies on MCD was implemented using an Activation Likelihood Estimation (ALE). We calculated differences between patients and healthy controls as well as between affected versus unaffected sides in addition to an overall analysis in order to identify neuronal areas related to MCD. RESULTS: Patients with MCD differ from healthy controls in the amygdala, superior temporal lobe, retrosplenial area, primary motor cortex, insula, red nucleus, thalamus, anterior as well as dorsolateral prefrontal and frontal cortex. When comparing affected versus unaffected sides, temporal cortex, dorsal anterior cingulate cortex, supramarginal gyrus, dorsal temporal lobe, anterior insula, primary somatosensory cortex, superior frontal gyrus and anterior prefrontal as well as frontal cortex show significant differences. CONCLUSIONS: Neuronal areas seem to be involved in the pathogenesis, maintenance or as a result of MCD. Areas that are important for motor-planning, motor-selection or autonomic response seem to be especially relevant. Our results support the emotional unawareness theory but also underline the need of more support by conduction imaging studies on both CD and MCD.

[Austrian expenditures on psychopharmaceutical drugs between 2006 and 2013]. / Analyse der Ausgaben für Psychopharmaka in Österreich von 2006 bis 2013.

OBJECTIVES: Health costs, which are increasing at a yearly rate of 4 %, represent 11% and thus a large share of Austria's gross domestic product (GDP). High expenditures derive frommental health care costs, including medication. In this article we investigate whether the costs and usage of psychopharmaceutic products in Austria are rising. METHOD: We did a descriptive analysis of the sales figures and number for packaging units of pharmaceutical products of ATC-classes N05 and N06 in all Austrian hospitals, pharmacies and medicine chests for the years 2006-2013. All data were provided free of charge by IMSHealth. RESULTS: The sales volume and number of prescribed packaging units of pharmaceuticals of ATC-classes N05 and N06 increased over the time period in question. In 2013, about 25% more packaging units were being sold than in 2006. Among the two ATC-classes, however, the indication subgroups developed differently. Expenditures increased a total of about 31%within the period of consideration. CONCLUSIONS: The increase in psycho-pharmaceutical sales exceeds the expansion rates of other health expenditures (17.8 %). During the 9 years of observation, 25% more psychopharmaceutical products were sold. This may result from increased prevalence of mental disorders, higher usage or an increment in prescriptions.

Assessment of psychological aspects of somatoform disorders: a study on the German version of the Health Attitude Survey (HAS).

OBJECTIVE: Given the prevalence and costs of somatoform disorders, it is important to identify and adequately treat these patients as early as possible. Instruments assessing experiences, perceptions, and behaviors of somatoform disorders are rare. In this study we evaluated the structure and validity of the German version of the Health Attitude Survey (HAS), a multidimensional self-report questionnaire for somatoform disorders. METHODS: This cross-sectional study involved 1452 participants. The sample was randomly split for independent exploratory (EFA) and confirmatory factor analyses (CFA). Each of the two samples (n1=726; n2=726) included patients with organic vertigo and current mental disorders (somatoform and other mental disorders). Somatic symptom burden was assessed using the Patient Health Questionnaire (PHQ-15). RESULTS: The CFA did not confirm the original HAS factor structure. The EFA revealed six factors. To enhance the fit of the model, we deleted two factors with the poorest reliability and items with low factor loadings. A modified and shortened version achieved good fit indices (CFI=0.92; RMSEA=0.068). It consists of 14 instead of 27 items and four scales ("dissatisfaction with care," "frustration with ill health," "high utilization of care," "excessive health worry"). HAS subscales discriminated among somatoform patients and physically ill and/or patients with a mental but not somatoform disorder, controlled for age, sex and number of (comorbid) mental diagnoses, confirming its construct validity. CONCLUSION: A modified shortened version of the HAS appears to be a reliable, valid, and economical instrument for assessing facets of somatoform disorders or of the recently published DSM-5 Somatic Symptom Disorder.

[How burdensome is the treatment of patients with somatoform disorders?]. / Wie belastend ist die Behandlung von Patienten mit somatoformen Störungen?

OBJECTIVES: This study examines the influence of self-perceived emotional stress during the treatment of patients with somatoform disorders. It asks whether emotional stress can be influenced by psychosomatic education. METHODS: Via online questionnaire general practitioners were asked about the prevalence of patients presenting with somatoform disorders and emotional stress during treatment. RESULTS: The prevalence of somatoform disorders in general practices was estimated at around 27.7 %. Practitioners educated in psychosomatic medicine estimate the prevalence of patients with somatoform disorders higher than practitioners without such education (n = 79; r = 0.242; p = 0.032). The treatment of patients presenting with somatoform disorders causes 42.6% more emotional stress among general practitioners compared with the treatment of an average patient (n = 79; t = 16.67; p ≤ 0.001). Doctors with additional education in psychosomatic medicine rate stress 17.2% lower than doctors without such education (n = 79; t = 1.875; p = 0.033). CONCLUSIONS: General practitioners experience the treatment of patients presenting with somatoform disorders as emotionally stressful. This emotional stress is mainly explained by increases in time expenditure, but it can be reduced by additional psychosomatic education.

Effectiveness of a multimodal treatment program for somatoform pain disorder.

Chronic pain conditions are highly prevalent, with somatoform pain disorder accounting for a large proportion. However, the psychological forms of treatment currently used achieve only small to medium effect sizes. This retrospective study investigated the effectiveness of a 5-week multimodal pain program for patients with somatoform pain disorder. The diagnosis of somatoform pain disorder was confirmed by a specialist for anesthesiology and pain management and a specialist for psychosomatic medicine. Therapy outcome was evaluated with a Numeric Rating Scale (NRS), the Pain Disability Index (PDI), and the Pain Perception Scale. Within the study sample (n = 100), all parameters showed a significant and clinically relevant improvement at the end of therapy (P values < 0.001). The highest effect sizes (d) were found for reduction in average pain rating (NRS: d = 1.00) and the affective items of the Pain Perception Scale (SES-A: d = 0.07). The lowest effect sizes were found for improvement of pain-related disabilities (PDI: d = 0.42) and sensory items of the Pain Perception Scale (SES-S: d = 0.50). Despite high chronification of pain condition, with average pain duration of greater than 8 years, the multimodal treatment program showed medium to large effect sizes on the outcome of patients with somatoform pain disorder. Compared with previous data with small to moderate effect sizes, a multimodal program seems to be more effective than other interventions to address somatoform pain disorder.
