Abstract
OBJECTIVE Cognitive behavior therapy (CBT) is the best-evaluated psychological approach to treat patients with medically unexplained symptoms (MUS). We still need a better understanding of what characterizes patients with MUS who benefit more or less from CBT. This systematic review aimed to identify patients' cognitive-emotional characteristics predicting the outcome of CBT for MUS. METHODS A systematic literature search (PubMed, PsycINFO, Web of Science) revealed 37 eligible studies, 23 of these provided data for meta-analyses. Mean correlation coefficients between predictor variables and the outcomes (symptom intensity, physical or social-emotional functioning) were calculated using a random-effects model. Differences between syndromes of MUS were investigated with moderator analyses. RESULTS Meta-analyses showed that patients with a comorbid mood disorder (r = 0.32, p < .01) or anxiety disorder (r = 0.18, p < .01), symptom catastrophizing and worries (r = 0.34, p < .01), tendencies of somatosensory amplification (r = 0.46, p = .04), and low symptom acceptance or self-efficacy (r = 0.25, p < .01) have a less favorable CBT outcome. Moderator analyses revealed that these associations between predictors and treatment outcome are pronounced in patients with chronic fatigue syndrome and irritable bowel syndrome. CONCLUSIONS Our results show that pre-treatment differences in patients' cognitive-emotional characteristics predict patients' outcome in CBT. Patient-tailored CBT could be a promising approach to address MUS patients' widely varying needs more effectively. PROTOCOL REGISTRATION The protocol of this systematic review and meta-analysis was registered in the PROSPERO registry (CRD 42018098649).

Moderating Effects of Alexithymia on Associations between the Therapeutic Alliance and the Outcome of Brief Psychodynamic-Interpersonal Psychotherapy for Multisomatoform Disorder.

Abstract
This secondary analysis of a trial on brief psychodynamic-interpersonal therapy (PIT) for patients with multisomatoform disorder investigated whether alexithymia moderates the associations between the therapeutic alliance and the outcome of PIT and whether moderating effects of alexithymia remain significant when controlling for depression. Eighty-three patients with multisomatoform disorder receiving PIT were statistically analyzed. Moderation analyses were performed with the SPSS macro PROCESS. The primary outcome (Y), self-reported physical quality of life at 9-month after the end of PIT, was measured with the physical component summary (PCS) of the SF-36 Health Survey. The potential moderator (M) alexithymia was operationalized with the Toronto Alexithymia Scale (TAS-20) at pre-treatment and the predictor (X) the therapeutic alliance was rated by both patients and therapists via the Helping Alliance Questionnaire (HAQ) at the end of PIT. Moreover, the PCS at pre-treatment functioned as covariate in all moderation models. When the patients' alliance ratings were analyzed, alexithymia did not moderate associations between the alliance and the outcome. When the therapists' alliance ratings were evaluated, alexithymia moderated the relationship between the alliance and the outcome (p < 0.05): a stronger alliance in the therapists' perspective was beneficial for the outcome only for patients scoring above 61 on the TAS-20. This moderating effect of alexithymia was, however, not statistically significant anymore when adding the pre-treatment depression scores (PHQ-9) as a covariate to the moderation model. The results underline the importance of a good therapists' view of the alliance when treating alexithymic patients and highlight the complex interaction between alexithymia and depression. Future studies are needed to extend the scope of research regarding which psychotherapeutic mechanisms of change are beneficial for which patients.

Abstract
There continues to be debate about the influence of personality disorder on the outcome of depressive disorders and is relative interactions with treatment. To determine whether personality disorder, both generically and in terms of individual clusters, leads to a worse outcome in patients with depressive disorders and whether this is influenced by type of treatment, a systematic electronic search of MEDLINE, CINAHL, and PsycINFO from 1966, 1982, and 1882, respectively, until February 2007 was undertaken. The keyword terms depression, mental illness, and personality disorder were used. All references were reviewed and personal correspondence was undertaken. Only English language papers were considered. Any English language paper studying a depressed adult population was considered for inclusion. Studies needed to clearly define depression and personality disorder using peer-reviewed instruments or International Classification of Disease/Diagnostic Statistical Manual criteria. Outcome assessment at greater than 3 weeks was necessary. Final inclusion papers were agreed on by consensus by at least two reviewers. All data were extracted using predetermined criteria for depression by at least two reviewers in parallel. Disagreement was settled by consensus. Complex data extraction was confirmed within the study group. Data were synthesized using log odds ratios in the Cochrane RevMan 5 program. The finding of comorbid personality disorder and depression was associated with a more than double the odds of a poor outcome for depression compared with those with no personality disorder (OR 2.16, CI 1.83-2.56). This effect was not ameliorated by the treatment modality used for the depressive disorder. This finding led to the conclusion that personality disorder has a negative impact on the outcome of depression. This finding is important in considering prognosis in depressive disorders.

Patients with unexplained physical symptoms have poorer quality of life and higher costs than other patient groups: a cross-sectional study on burden. BMC Health Serv Res 2013; 13:520. [PMID: 24344899 PMCID: PMC3878564 DOI: 10.1186/1472-6963-13-520] [Citation(s) in RCA: 52] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2013] [Accepted: 12/09/2013] [Indexed: 12/02/2022] Open
Abstract
Background To determine whether healthcare resources are allocated fairly, it is helpful to have information on the quality of life (QoL) of patients with Unexplained Physical Symptoms (UPS) and on the costs associated with them, and on how these relate to corresponding data in other patient groups. As studies to date have been limited to specific patient populations with UPS, the objective of this study was to assess QoL and costs in a general sample of patients with UPS using generic measures. Methods In a cross-sectional study, 162 patients with UPS reported on their QoL, use of healthcare resources and lost productivity in paid and unpaid work. To assess QoL, the generic SF-36 questionnaire was used, from which multidimensional quality-of-life scores and a one-dimensional score (utility) using the SF-6D scorings algorithm were derived. To assess costs, the TiC-P questionnaire was used. Results Patients with UPS reported a poor QoL. Their QoL was mostly decreased by limitations in functioning due to physical health, and the least by limitations in functioning due to emotional problems. The median of utilities was 0.57, and the mean was 0.58 (SD = .09). The cost for the use of healthcare services was estimated to be €3,123 (SD = €2,952) per patient per year. This cost was enlarged by work-related costs: absence from work (absenteeism), lower on-the-job productivity (presenteeism), and paid substitution of domestic tasks. The resulting mean total cost was estimated to be €6,815 per patient per year. Conclusions These findings suggest that patients with UPS have a high burden of disease and use a considerable amount of healthcare resources. In comparison with other patient groups, the QoL values of patients with UPS were among the poorest and their costs were among the highest of all patient groups. The burden for both patients and society helps to justify the allocation of sufficient resources to effective treatment for patients with UPS. Trial registration Nederlands Trial Register, NTR1609

Predicting the outcome of a cognitive-behavioral group training for patients with unexplained physical symptoms: a one-year follow-up study. BMC Public Health 2012; 12:848.

Abstract
Background Although Cognitive-Behavioral Therapy (CBT) is effective for Unexplained Physical Symptoms (UPS), some therapists in clinical practice seem to believe that CBT outcome will diminish if psychiatric comorbidity is present. The result is that patients with a psychiatric comorbidity are redirected from treatment for UPS into treatment for mental health problems. To explore whether this selection and allocation are appropriate, we explored whether CBT outcomes in UPS could be predicted by variables assessed at baseline and used in routine-practice assessments. Methods Patients (n=162) with UPS classified as undifferentiated somatoform disorder or chronic pain disorder were followed up until one year after they had attended a CBT group training. The time-points of the follow-up were at the end of CBT (immediate outcome), three months after CBT (short-term outcome), and one year after CBT (long-term outcome). CBT outcome was measured using the Physical Component Summary of the SF-36, which was the primary outcome measure in the randomized controlled trial that studied effectiveness of the CBT group training. Predictors were: 1.) psychological symptoms (global severity score of SCL-90), 2.) personality-disorder characteristics (sum of DSM-IV axis II criteria confirmed), 3.) psychiatric history (past presence of DSM-IV axis I disorders), and 4.) health-related quality of life in the mental domain (mental component summary of SF-36). The effect of this predictor set was explored using hierarchical multiple regression analyses into which these predictors had been entered simultaneously, after control for: a.) pretreatment primary outcome scores, b.) age, c.) gender, d.) marital status, and e.) employment. Results The predictor set was significant only for short-term CBT outcome, where it explained 15% of the variance. A better outcome was predicted by more psychological symptoms, fewer personality-disorder characteristics, the presence of a psychiatric history, and a better quality of life in the mental domain. Conclusions As the predictors do not seem to predict CBT outcome consistently over time, the need for selection and allocation of patients for CBT is doubtful. It seems that this would unnecessarily deprive patients of effective treatment. Trial registration Nederlands Trial Register, NTR1609

Abstract
BACKGROUND Although cognitive-behavioral therapy for Unexplained Physical Symptoms (UPS) is effective in secondary care, studies done in primary care produced implementation problems and conflicting results. We evaluated the effectiveness of a cognitive-behavioral group training tailored to primary care patients and provided by a secondary community mental-health service reaching out into primary care. METHODOLOGY/PRINCIPAL FINDINGS The effectiveness of this training was explored in a randomized controlled trial. In this trial, 162 patients with UPS classified as undifferentiated somatoform disorder or as chronic pain disorder were randomized either to the training or a waiting list. Both lasted 13 weeks. The preservation of the training's effect was analyzed in non-randomized follow-ups, for which the waiting group started the training after the waiting period. All patients attended the training were followed-up after three months and again after one year. The primary outcomes were the physical and the mental summary scales of the SF-36. Secondary outcomes were the other SF-36-scales and the SCL-90-R. The courses of the training's effects in the randomized controlled trial and the follow-ups were analyzed with linear mixed modeling. In the randomized controlled trial, the training had a significantly positive effect on the quality of life in the physical domain (Cohen's d = 0.38;p = .002), but this overall effect was not found in the mental domain. Regarding the secondary outcomes, the training resulted in reporting an improved physical (Cohen's d = 0.43;p = 0.01), emotional (Cohen's d = 0.44;p = 0.01), and social (Cohen's d = 0.36;p = 0.01) functioning, less pain and better functioning despite pain (Cohen's d = 0.51;p = <0.001), less physical symptoms (Cohen's d = -.23;p = 0.05) and less sleep difficulties (Cohen's d = -0.25;p = 0.04) than time in the waiting group. During the non-randomized follow-ups, there were no relapses. CONCLUSIONS/SIGNIFICANCE The cognitive-behavioral group training tailored for UPS in primary care and provided by an outreaching secondary mental-health service appears to be effective and to broaden the accessibility of treatment for UPS.

Abstract
Dysfunctions of the brain 5-HT system are often associated with affective disorders, such as depression. The raphe nuclei target the limbic system and most forebrain areas and constitute the main source of 5-HT in the brain. All 5-HT neurons express tryptophan hydroxylase-2 (TPH2), the brain specific, rate-limiting enzyme for 5-HT synthesis. Estrogen receptor (ER) beta agonists have been shown to attenuate anxiety- and despair-like behaviors in rodent models. Therefore, we tested the hypothesis that ER beta may contribute to the regulation of gene expression in 5-HT neurons of the dorsal raphe nuclei (DRN) by examining the effects of systemic and local application of the selective ER beta agonist diarylpropionitrile (DPN) on tph2 mRNA expression. Ovariectomized (OVX) female rats were injected s.c. with DPN or vehicle once daily for 8 days. In situ hybridization revealed that systemic DPN-treatment elevated basal tph2 mRNA expression in the caudal and mid-dorsal DRN. Behavioral testing of all animals in the open field (OF) and on the elevated plus maze (EPM) on days 6 and 7 of treatment confirmed the anxiolytic nature of ER beta activation. Another cohort of female OVX rats was stereotaxically implanted bilaterally with hormone-containing wax pellets flanking the DRN. Pellets contained 17-beta-estradiol (E), DPN, or no hormone. Both DPN and E significantly enhanced tph2 mRNA expression in the mid-dorsal DRN. DPN also increased tph2 mRNA in the caudal DRN. DPN- and E-treated rats displayed a more active stress-coping behavior in the forced-swim test (FST). No behavioral differences were found in the OF or on the EPM. These data indicate that ER beta acts at the level of the rat DRN to modulate tph2 mRNA expression and thereby influence 5-HT synthesis in DRN subregions. Our results also suggest that local activation of ER beta neurons in the DRN may be sufficient to decrease despair-like behavior, but not anxiolytic behaviors.

Abstract
BACKGROUND There is conflicting evidence about the influence of personality disorder on outcome in depressive disorders. AIMS Meta-analysis of studies in which a categorical assessment of personality disorder or no personality disorder was made in people with depressive disorders, and categorical outcome (recovered/not recovered) also determined. METHOD Systematic electronic search of the literature for relevant publications. Hand searches of Journal of Affective Disorders and recent reviews, with subsequent meta-analysis of selected studies. RESULTS Comorbid personality disorder with depression was associated with a doubling of the risk of a poor outcome for depression compared with no personality disorder (random effects model OR=2.18, 95% CI 1.70-2.80), a robust finding maintained with only Hamilton-type depression criteria at outcome (OR=2.20, 95% CI 1.61-3.01). All treatments apart from electroconvulsive therapy (ECT) showed this poor outcome, and the ECT group was small. CONCLUSIONS Combined depression and personality disorder is associated with a poorer outcome than depression alone.

Abstract
Modern cognitive behavioral approaches for the treatment of patients with medically unexplained somatic symptoms have been developed on the basis of the classification systems DSM-IV and ICD-10. These systems define somatoform disorders as a homogeneous clinical group. Behavior therapy has additionally developed vicious circle models specifying etiological, triggering and maintaining factors. Treatment goals and strategies can be derived directly from these models. The main components are: (1) motivation of patients to accept the psychotherapeutic approach; (2) introduction of alternative explanations of the symptoms on the basis of both biomedical as well as psychosocial mechanisms; (3) evaluation of the new explanations by patient and therapist; (4) reduction of avoidance and inadequate illness behaviour. Health economical aspects are particularly important because patients with somatoform disorders tend to overuse medical services and are thus considered an expensive problem group for the health system.

Abstract
To examine the nature and extent of personality dysfunction related to somatization, the authors administered the Structured Interview for DSM-IV Personality and the NEO Five-Factor Inventory to a series of somatizing and nonsomatizing patients in a general medicine clinic. A greater percentage of somatizers met criteria for one or more DSM-IV personality disorders, especially obsessive-compulsive disorder, than did control patients. Somatizers also differed from control patients with respect to self-defeating, depressive, and negativistic personality traits and scored higher on the dimension of neuroticism and lower on the dimension of agreeableness. In addition, initial and facultative somatizers showed more personality pathology than true somatizers. These findings suggest that certain personality disorders and traits contribute to somatization by way of increased symptom reporting and care-seeking behavior.
