Reliability, validity and responsiveness of the EQ-5D in assessing and valuing health status in patients with social phobia
2013
Abstract Objective The aim of the study was to analyse the psychometric properties of the EQ-5D in patients with social phobia. Methods We used a sample of 445 patients with social phobia with five measurement points over a 30 month period. The discriminative ability of the EQ-5D was analysed by comparing the patients’ responses with the general population and between different disease severity levels. For test-retest reliability we assessed the level of agreement in patients’ responses over time, when there was no change in the Liebowitz Social Anxiety Scale (LSAS). Construct validity was analysed by identifying correlations of the EQ-5D with more specific instruments. For responsiveness w…
The costs of social anxiety disorder: The role of symptom severity and comorbidities
2013
Abstract Background Social anxiety disorder (SAD) is associated with low direct costs compared to other anxiety disorders while indirect costs tend to be high. Mental comorbidities have been identified to increase costs, but the role of symptom severity is still vague. The objective of this study was to determine the costs of SAD, and to explore the impact of symptoms and comorbidities on direct and indirect costs. Methods Baseline data, collected within the SOPHO-NET multi-centre treatment study ( N =495), were used. Costs were calculated based on health care utilization and lost productivity. Symptom severity was measured with the Liebowitz-Social-Anxiety-Scale; comorbidities were include…
Short-term cost-effectiveness of psychodynamic therapy and cognitive-behavioral therapy in social anxiety disorder: Results from the SOPHO-NET trial
2015
Abstract Background To investigate the short-term cost-effectiveness of cognitive-behavioral therapy (CBT) and psychodynamic therapy (PDT) compared to waiting list (WL). Methods The analysis was conducted alongside the SOPHO-NET multi-center efficacy trial. Patients were randomly assigned to CBT ( n =209), PDT ( n =207), or WL ( n =79). Resource use was assessed prior and during treatment to determine direct and absenteeism costs. Unadjusted incremental cost-effectiveness ratios (ICERs) were calculated based on remission and response rates. To visualize statistical uncertainty, cost-effectiveness acceptability curves (CEACs) were constructed based on adjusted net-benefit regression. Differe…
Excess costs of social anxiety disorder in Germany
2017
Abstract Background Social anxiety disorder is one of the most frequent mental disorders. It is often associated with mental comorbidities and causes a high economic burden. The aim of our analysis was to estimate the excess costs of patients with social anxiety disorder compared to persons without anxiety disorder in Germany. Methods Excess costs of social anxiety disorder were determined by comparing two data sets. Patient data came from the SOPHO-NET study A1 (n=495), whereas data of persons without anxiety disorder originated from a representative phone survey (n=3213) of the general German population. Missing data were handled by “Multiple Imputation by Chained Equations”. Both data se…
SOPHO-NET – Forschungsverbund zur Psychotherapie der Sozialen Phobie
2009
This paper presents the Social Phobia Psychotherapy Research Network (SOPHO-NET). SOPHO-NET is among the five research networks on psychotherapy funded by "Bundesministerium fur Bildung und Forschung". The research program encompasses a coordinated group of studies of social phobia. In the central project (Study A), a multi-center randomized controlled trial, refined models of manualized cognitive-behavioral therapy (CBT) and manualized short-term psychodynamic psychotherapy (STPP) are compared in the treatment of social phobia. A sample of n=512 outpatients will be randomized to either CBT, STPP or wait list. For quality assurance and treatment integrity, a specific project has been establ…
Long-term cost-effectiveness of cognitive behavioral therapy versus psychodynamic therapy in social anxiety disorder.
2015
Background To determine the cost-effectiveness of cognitive behavioral therapy (CBT) versus psychodynamic therapy (PDT) in the treatment of social anxiety disorder after a follow-up of 30 months from a societal perspective. Methods This analysis was conducted alongside the multicenter SOPHO-NET trial; adults with a primary diagnosis of social anxiety disorder received CBT (n = 209) or PDT (n = 207). Data on health care utilization and productivity loss were collected at baseline, after 6 months (posttreatment), and three further follow-ups to calculate direct and indirect costs. Anxiety-free days (AFDs) calculated based on remission and response were used as measure of effect. The increment…
Co-morbid mental health conditions in cancer patients at working age - prevalence, risk profiles, and care uptake
2013
Summary Objective This study examined the prevalence of mental health conditions in cancer patients, the role of socioeconomic position in relation to that, and the use of professional mental health care. Methods Prospective cohort with measurements at the beginning of inpatient treatment (baseline) and 3, 9, and 15 months after baseline using structured clinical interviews based on DSM-IV, questionnaires, and medical records. Results At baseline, 149 out of 502 cancer patients (30%) were diagnosed with a mental health condition. Prevalence was associated with unemployment (odds ratio [OR] 2.0), fatigue (OR 1.9), and pain (OR 1.7). Of those with mental health conditions, 9% saw a psychother…
