The serotonin theory of depression: a systematic umbrella review of the evidence.

The serotonin hypothesis of depression is still influential. We aimed to synthesise and evaluate evidence on whether depression is associated with lowered serotonin concentration or activity in a systematic umbrella review of the principal relevant areas of research. PubMed, EMBASE and PsycINFO were searched using terms appropriate to each area of research, from their inception until December 2020. Systematic reviews, meta-analyses and large data-set analyses in the following areas were identified: serotonin and serotonin metabolite, 5-HIAA, concentrations in body fluids; serotonin 5-HT1A receptor binding; serotonin transporter (SERT) levels measured by imaging or at post-mortem; tryptophan depletion studies; SERT gene associations and SERT gene-environment interactions. Studies of depression associated with physical conditions and specific subtypes of depression (e.g. bipolar depression) were excluded. Two independent reviewers extracted the data and assessed the quality of included studies using the AMSTAR-2, an adapted AMSTAR-2, or the STREGA for a large genetic study. The certainty of study results was assessed using a modified version of the GRADE. We did not synthesise results of individual meta-analyses because they included overlapping studies. The review was registered with PROSPERO (CRD42020207203). 17 studies were included: 12 systematic reviews and meta-analyses, 1 collaborative meta-analysis, 1 meta-analysis of large cohort studies, 1 systematic review and narrative synthesis, 1 genetic association study and 1 umbrella review. Quality of reviews was variable with some genetic studies of high quality. Two meta-analyses of overlapping studies examining the serotonin metabolite, 5-HIAA, showed no association with depression (largest n = 1002). One meta-analysis of cohort studies of plasma serotonin showed no relationship with depression, and evidence that lowered serotonin concentration was associated with antidepressant use (n = 1869). Two meta-analyses of overlapping studies examining the 5-HT1A receptor (largest n = 561), and three meta-analyses of overlapping studies examining SERT binding (largest n = 1845) showed weak and inconsistent evidence of reduced binding in some areas, which would be consistent with increased synaptic availability of serotonin in people with depression, if this was the original, causal abnormaly. However, effects of prior antidepressant use were not reliably excluded. One meta-analysis of tryptophan depletion studies found no effect in most healthy volunteers (n = 566), but weak evidence of an effect in those with a family history of depression (n = 75). Another systematic review (n = 342) and a sample of ten subsequent studies (n = 407) found no effect in volunteers. No systematic review of tryptophan depletion studies has been performed since 2007. The two largest and highest quality studies of the SERT gene, one genetic association study (n = 115,257) and one collaborative meta-analysis (n = 43,165), revealed no evidence of an association with depression, or of an interaction between genotype, stress and depression. The main areas of serotonin research provide no consistent evidence of there being an association between serotonin and depression, and no support for the hypothesis that depression is caused by lowered serotonin activity or concentrations. Some evidence was consistent with the possibility that long-term antidepressant use reduces serotonin concentration.

Prevalence, trends, and individual patterns of long-term antidepressant medication use in the adult Swiss general population.

PURPOSE: Antidepressant use has increased in many European countries, mostly driven by longer treatment duration. The aim of this study was to provide prevalence rates of long-term users of antidepressants for the Swiss population over the last decade and to investigate associated factors for longer use. METHODS: We examined the prevalence rates of individuals with at least one prescription for antidepressants using longitudinal health claims data for 2013 to 2021. We defined short- (< one year), medium- (one-two years), and long-term users (> two years) for 2015 to 2019. We applied a binary logistic regression model to investigate the effects of population (gender, age, area of living, language, health insurance plan, and nursing home) and treatment characteristics (psychiatric or psychotherapeutic care) on long-term compared to short- and medium-term users in 2019. RESULTS: In 2021, 9% of the Swiss population (n = 770,698) received at least one antidepressant prescription, which remained stable since 2013. In 2019, the proportion of long-term users was 57.4%, with steady increase since 2015. The proportion of medium- and short-term users has decreased. Older age, being a woman, living in an urban area, living in a nursing home, being enrolled in a standard care plan, and receiving psychiatric or psychotherapeutic care were factors positively associated with being a long-term user. CONCLUSION: The proportion of long-term users in Switzerland is high and steadily increasing. Given the ongoing debate about the confounding effects of relapse and withdrawal, more research is needed to investigate longer use of antidepressants that could indicate overprescribing.

Patterns of internalizing symptoms and disability functioning in children and adolescents.

Despite findings from previous studies, there is still little consistent knowledge regarding the co-occurrence patterns of somatic, depressive and anxiety symptoms in childhood and adolescence. Moreover, functional disability due to somatic symptoms at different concomitant levels of depression and anxiety is understudied. The present study examined the co-occurrence patterns of somatic symptoms and symptoms of depression and anxiety, in children and adolescents using two-step cluster analysis. Differences in functional disability due to somatic symptoms were tested with ANCOVA controlling for gender and age. The sample comprised 1127 Italian children and adolescents (48.7% males, n = 549) aged 8-16 years (Mage = 11.7, SD = 2.37). Data were collected using the Children Somatization Inventory-24, the Children Depression Inventory, the Screen for Child Anxiety Related Emotional Disorders, and the Functional Disability Inventory. A four-cluster solution based on the co-occurrence of internalizing symptoms best fit the data. The four clusters were labelled as follows: cluster 1: "High somatic symptoms and average depression/anxiety"; cluster 2: "High somatic symptoms and high depression/anxiety"; cluster 3: "Average somatic symptoms and above average depression/anxiety"; and cluster 4: "Low somatic symptoms and low depression/anxiety". Significant differences between the four groups according to gender and age were shown. Participants with high levels of somatic, depressive, and anxiety symptoms reported greater functional disability due to somatic symptoms than the other three groups. Our findings indicate that children and adolescents who demonstrate high symptoms of depression and anxiety also reported higher levels of disability in daily life due to somatic symptoms.

Cognitive function in association with high estradiol levels resulting from fertility treatment.

The putative association between hormones and cognitive performance is controversial. While there is evidence that estradiol plays a neuroprotective role, hormone treatment has not been shown to improve cognitive performance. Current research is flawed by the evaluation of combined hormonal effects throughout the menstrual cycle or in the menopausal transition. The stimulation phase of a fertility treatment offers a unique model to study the effect of estradiol on cognitive function. This quasi-experimental observational study is based on data from 44 women receiving IVF in Zurich, Switzerland. We assessed visuospatial working memory, attention, cognitive bias, and hormone levels at the beginning and at the end of the stimulation phase of ovarian superstimulation as part of a fertility treatment. In addition to inter-individual differences, we examined intra-individual change over time (within-subject effects). The substantial increases in estradiol levels resulting from fertility treatment did not relate to any considerable change in cognitive functioning. As the tests applied represent a broad variety of cognitive functions on different levels of complexity and with various brain regions involved, we can conclude that estradiol does not show a significant short-term effect on cognitive function.

Did the introduction and increased prescribing of antidepressants lead to changes in long-term trends of suicide rates?

BACKGROUND: Ecological studies have explored associations between suicide rates and antidepressant prescriptions in the population, but most of them are limited as they analyzed short-term correlations that may be spurious. The aim of this long-term study was to examine whether trends in suicide rates changed in three European countries when the first antidepressants were introduced in 1960 and when prescription rates increased steeply after 1990 with the introduction of the serotonin reuptake inhibitors (SSRIs). METHODS: Data were extracted from the WHO Mortality Database. Suicide rates were calculated for people aged 10-89 years from 1951-2015 for Italy, 1955-2016 for Austria and 1951-2013 for Switzerland. Trends in suicide rates stratified by gender were analyzed using joinpoint regression models. RESULTS: There was a general pattern of long-term trends that was broadly consistent across all three countries. Suicide rates were stable or decreasing during the 1950s and 1960s, they rose during the 1970s, peaked in the early 1980s and thereafter they declined. There were a few notable exceptions to these general trends. In Italian men, suicide rates increased until 1997, then fell sharply until 2006 and increased again from 2006 to 2015. In women from all three countries, there was an extended period during the 2000s when suicide rates were stable. No trend changes occurred around 1960 or 1990. CONCLUSIONS: The introduction of antidepressants around 1960 and the sharp increase in prescriptions after 1990 with the introduction of the SSRIs did not coincide with trend changes in suicide rates in Italy, Austria or Switzerland.

Swiss GPs' preferences for antidepressant treatment in mild depression: vignette-based quantitative analysis.

BACKGROUND: GPs frequently prescribe antidepressants in mild depression. The aim of this study was to examine, how often Swiss GPs recommend antidepressants in various clinical presentations of mild depression and which factors contribute to antidepressant treatment recommendations. METHODS: We conducted an online survey among Swiss GPs with within-subject effect analysis. Alternating case vignettes described a typical female case of mild depression according to International Classification of Diseases, 10th edition criteria, with and without anxiety symptoms and sleep problems. GPs indicated for each vignette their preferred treatments (several recommendations were possible). Additionally, we assessed GP characteristics, attitudes towards depression treatments, and elements of clinical decision-making. RESULTS: Altogether 178 GPs completed the survey. In the initial description of a case with mild depression, 11% (95%-CI: 7%-17%) of GPs recommended antidepressants. If anxiety symptoms were added to the same case, 29% (23%-36%) recommended antidepressants. If sleep problems were mentioned, 47% (40%-55%) recommended antidepressants, and if both sleep problems and anxiety symptoms were mentioned, 63% (56%-70%) recommended antidepressants. Several factors were independently associated with increased odds of recommending antidepressants, specifically more years of practical experience, an advanced training in psychosomatic and psychosocial medicine, self-dispensation, and a higher perceived effectiveness of antidepressants. By contrast, a higher perceived influence of patient characteristics and the use of clinical practice guidelines were associated with reduced odds of recommending antidepressants. CONCLUSIONS: Consistent with depression practice guidelines, Swiss GPs rarely recommended antidepressants in mild depression if no co-indications (i.e., sleep problems and anxiety symptoms) were depicted. However, presence of sleep problems and anxiety symptoms, many years of practical experience, overestimation of antidepressants' effectiveness, self-dispensation, an advanced training in psychosomatic and psychosocial medicine, and non-use of clinical practice guidelines may independently lead to antidepressant over-prescribing.

'Placement budgets' for supported employment: impact on employment rates in a multicentre randomised controlled trial.

BACKGROUND: The most effective rehabilitation model for job (re-)entry of people with mental illness is supported employment. A barrier to introducing supported employment into standard care is its temporally unlimited provision, which conflicts with health and social legislation in many European countries. AIMS: To test the impact of different 'placement budgets', i.e. a predefined maximum time budget for job seeking until take-up of competitive employment. METHOD: Participants (116) were randomly assigned to 25 h, 40 h or 55 h placement budgets in an intent-to-treat analysis. We applied the individual placement and support model over 24 months, following participants for 36 months. Primary outcome was employment in the labour market for at least 3 months. RESULTS: The proportion of participants obtaining competitive employment was 55.1% in the 25 h group, 37.8% in the 40 h group and 35.8% in the 55 h group. In a Cox regression analysis, time to employment was slightly lower in the 25 h group relative to the 40 h (hazard ratio 1.78, 95% CI 0.88-3.57, P = 0.107) and 55 h groups (hazard ratio 1.74, 95% CI 0.86-3.49, P = 0.122), but this was not statistically significant. The vast majority of all participants who found a job did so within the first 12 months (80.4%). CONCLUSION: A restricted time budget for job finding and placement does not affect the rate of successful employment. In accordance with legislation, a restriction of care provision seems justified and enhances the chances of supported employment being introduced in statutory services.

Comparative efficacy of placebos in short-term antidepressant trials for major depression: a secondary meta-analysis of placebo-controlled trials.

BACKGROUND: The issue of unblinded outcome-assessors and patients has repeatedly been stressed as a flaw in allegedly double-blind antidepressant trials. Unblinding bias can for example result from a drug's marked side effects. If such unblinding bias is present for a given drug, then it might be expected that the placebos of that drug are rated significantly less effective than that of other antidepressants. METHODS: To test this hypothesis, the present exploratory analysis conducted a Bayesian network meta-analysis (NMA) comparing the efficacy of 19 different placebos in placebo-controlled trials provided in the dataset by Cipriani et al. (Lancet 2018; 391: 1357-66). Primary outcome was efficacy (continuous) estimated on the standardized mean difference (SMD) scale and defined as the pre-post change on the Hamilton Depression scale (HAMD-17), on which information was available in N = 258 trials. RESULTS: Comparative placebo ranking suggested mirtazapine-placebo (SMD -2.0 [- 5.0-1.0 95% CrI]) to be the most, and amitriptyline- (SMD 1.2 [- 1.6-3.9 95% CrI]) and trazodone- (SMD 2.1 [- 0.9-5.2 95% CrI]) placebos to be the least effective placebos. Other placebos suggested to be more effective than amitriptyline- and trazodone-placebos (based on 95% CrIs excluding zero) were citalopram, desvenlafaxine, duloxetine, escitalopram, fluoxetine, sertraline, and venlafaxine placebos. These NMA results were corroborated by the observation that the relative efficacy between drug and placebo was considerably larger for amitriptyline and trazodone than for instance mirtazapine, duloxetine, and venlafaxine, supported by a small and insignificant correlation between drug-efficacy and placebo-efficacy (r = - 0.202, p = 0.408). DISCUSSION: The present exploratory NMA indicates that distinguishable side effects of older drugs may unblind outcome-assessors thus resulting in overestimation of the average drug-placebo difference and underrating bias in placebo-arms, particularly for the older antidepressant drugs amitriptyline and trazodone. If confirmed in prospective studies, these findings suggest that efficacy rankings for antidepressants are susceptible to bias and should be considered unreliable or misleading. The analysis is limited by the focus on the single-comparison placebos (76%, i.e., placebos assessed in two-arm trials), since double-comparison placebos (25%, i.e., placebos assessed in three-arm trials) are hard to interpret and therefore not included in the present interpretation. Another limitation is the problem of multiplicity, which was only approximately accounted for in the Bayesian NMA by modelling treatment effects as exchangeable.

Guidelines for the pharmacological acute treatment of major depression: conflicts with current evidence as demonstrated with the German S3-guidelines.

Several international guidelines for the acute treatment of moderate to severe unipolar depression recommend a first-line treatment with antidepressants (AD). This is based on the assumption that AD obviously outperform placebo, at least in the case of severe depression. The efficacy of AD for severe depression can only be definitely clarified with individual patient data, but corresponding studies have only been available recently. In this paper, we point out discrepancies between the content of guidelines and the scientific evidence by taking a closer look at the German S3-guidelines for the treatment of depression. Based on recent studies and a systematic review of studies using individual patient data, it turns out that AD are marginally superior to placebo in both moderate and severe depression. The clinical significance of this small drug-placebo-difference is questionable, even in the most severe forms of depression. In addition, the modest efficacy is likely an overestimation of the true efficacy due to systematic method biases. There is no related discussion in the S3-guidelines, despite substantial empirical evidence confirming these biases. In light of recent data and with their underlying biases, the recommendations in the S3-guidelines are in contradiction with the current evidence. The risk-benefit ratio of AD for severe depression may be similar to the one estimated for mild depression and thus could be unfavorable. Downgrading of the related grade of recommendation would be a logical consequence.

Scientific debate instead of beef; challenging misleading arguments about the efficacy of antidepressants.

In a recent commentary with the polemic title 'Antidepressants; what's the beef?', Goodwin and Nutt argued that the benefit-risk ratio of antidepressants had been questioned inappropriately (Goodwin & Nutt, 2019). Personally I think it is a great achievement that our medical system can offer pharmacological treatments to people who suffer from serious clinical depression, and like Goodwin and Nutt I accept that antidepressants may be useful in some patients (Hengartner & Plöderl, 2018). Nevertheless, and this is where my position deviates from Goodwin and Nutt, I am also concerned about the overestimation of efficacy and the minimisation of harm (Hengartner, 2017). There are many misrepresentations in the commentary by Goodwin and Nutt, all of which systematically inflate the apparent benefits of antidepressants, and in this letter, I will discuss five of them.

Articulation and testing of a personality-centred model of psychopathology: evidence from a longitudinal community study over 30 years.

Advances in psychopathological research advocate a personality-centred model of common mental disorders (CMD). We tested four hypotheses to test such a model. First, personality relates to critical life events; second, both personality and critical life events relate to CMD; third, interaction effects between personality and critical life events relate to CMD; fourth, neuroticism explains the majority of variance in psychopathology. We analysed data (n = 453) based on seven semi-structured interviews from a longitudinal epidemiologic cohort study over 30 years spanning years 1979 (age 20) to 2008 (age 50). CMD and critical life events were assessed seven times between 1979 and 2008 and personality domains of neuroticism, extraversion and aggressiveness in 1988 and 1993. Aggressiveness and neuroticism related to partnership rupture and job loss. Neuroticism related significantly to major depression, anxiety disorders, substance-use disorders (SUD) and severity of psychopathology. Both partnership rupture and job loss related to major depression and severity of psychopathology, but not to anxiety disorder or SUD. An interaction effect between neuroticism and partnership rupture pointed towards significantly increased SUD prevalence. All associations held when additionally adjusted for childhood adversity and familial socio-economic status. According to a pseudo-R 2, neuroticism explained 51% of total variance in severity of psychopathology over time, while all three personality domains along with both partnership rupture and job loss explained 59% of total variance. In conclusion, personality, especially neuroticism, relates consistently to repeated measures of psychopathology. These associations are independent of and more pervasive than the effects of partnership rupture and job loss. Partnership rupture in interaction with neuroticism may further increase the risk for SUD. We conclude that neuroticism is a fundamental aetiological factor for severe psychopathology, but further testing of this model in other longitudinal studies is required.

Attachment anxiety and avoidance as mediators of the association between childhood maltreatment and adult personality dysfunction.

This paper tests the hypothesis that the association between childhood maltreatment and adult personality dysfunction is at least partially attributable to insecure attachment, that is that attachment style mediates the relationship between childhood maltreatment and adult personality dysfunction. Associations between childhood trauma, as measured by the Childhood Trauma Questionnaire (CTQ), anxious and avoidant attachment in romantic relationships, as measured by the Experiences in Close Relationships-Revised (ECR-R), and five personality domains, as measured by the Severity Indices of Personality Problems (SIPP-118), were examined in a sample of 72 psychiatric inpatients. The SIPP-118 domains included relational capacities, identity integration, self-control, responsibility, and social concordance. The direct effect of childhood trauma on all SIPP-118 domains was not significant after controlling for the indirect effect of attachment. In regression modeling, a significant indirect effect of childhood trauma via adult attachment style was found for SIPP-118 relational capacities, identity integration, self-control, and social concordance. Specifically, anxious attachment was a significant mediator of the effect of childhood trauma on self-control, identity integration, and relational domains. These results suggest that childhood trauma impacts a broad range of personality domains and does so in large part through the pathway of anxious romantic attachment style.

Treated versus non-treated subjects with depression from a 30-year cohort study: prevalence and clinical covariates.

The aim of this study was to determine prevalence rates of several components of depression (unipolar and bipolar major, minor, recurrent brief depression, and dysthymia) and to identify covariates of treatment. We analysed a representative population-based, long-term prospective cohort study from age 20 to 50. Across the seven semi-structured interviews, generalized estimating equations examined the associations between diagnoses and treatment status during the course. The results show that the mean annual treatment rate across 30 years in persons with MDE was 39.2%. The weighted treatment prevalence for any depressive disorder was 23.4% (15.7% for MDE, 4.3% for minor depressive disorders and 3.4% for non-diagnosed subjects). Persons were more likely to seek treatment as they grew older. Women with MDE had triple the treatment prevalence of men (23.8 vs. 7.4%). Variables of distress/suffering under depression (OR 1.36-1.52) and the number of diagnostic depressive symptoms (OR 1.47) were statistically significant predictors of treatment, as were episode duration (OR 2.21) and various variables assessing impairment due to depression (OR 4.65-8.02). In conclusion, only a minority of persons with depressive disorders seek professional treatment in the year of disorder onset. Women and subjects suffering from high levels of depressive symptoms, frequent episodes, long episode duration and consecutive high distress and impairment were more likely to seek treatment.

Pure animal phobia is more specific than other specific phobias: epidemiological evidence from the Zurich Study, the ZInEP and the PsyCoLaus.

Interest in subtypes of mental disorders is growing in parallel with continuing research progress in psychiatry. The aim of this study was to examine pure animal phobia in contrast to other specific phobias and a mixed subtype. Data from three representative Swiss community samples were analysed: PsyCoLaus (n = 3720), the ZInEP Epidemiology Survey (n = 1500) and the Zurich Study (n = 591). Pure animal phobia and mixed animal/other specific phobias consistently displayed a low age at onset of first symptoms (8-12 years) and clear preponderance of females (OR > 3). Meanwhile, other specific phobias started up to 10 years later and displayed almost a balanced sex ratio. Pure animal phobia showed no associations with any included risk factors and comorbid disorders, in contrast to numerous associations found in the mixed subtype and in other specific phobias. Across the whole range of epidemiological parameters examined in three different samples, pure animal phobia seems to represent a different entity compared to other specific phobias. The etiopathogenetic mechanisms and risk factors associated with pure animal phobias appear less clear than ever.

Factors influencing patients' recovery and the efficacy of a psychosocial post-discharge intervention: post hoc analysis of a randomized controlled trial.

PURPOSE: The aim of this post hoc analysis was to examine self-reported recovery following a post-discharge intervention and to focus on the moderators of this intervention programme. METHODS: RCT using parallel group block randomisation, including 151 patients with ≤3 hospitalisations within the last 3 years, a GAF score ≤60, and aged 18-64 years, assessed at two psychiatric hospitals from Zurich, Switzerland, between September 2011 and February 2014. In the present study, the main outcome was the OQ-45 as assessed prior to discharge from the index hospitalisation and at 12-month follow-up. Participants received either the post-discharge intervention provided by a social worker or treatment as usual (TAU). RESULTS: Patients in the intervention group showed substantially less recovery over the 12-month observation period than controls (d = 0.44). In the TAU group, 15.6 % remained clinically impaired at 12-month follow-up as opposed to 48.1 % in the intervention group (p = 0.001). Among participants in the intervention group, an interdisciplinary meeting of significant network members was associated with less recovery (d = 0.46). Involuntary index admission (d = 0.42) and high educational degree (d = 0.52) were significant moderators of the intervention. Both factors related to less recovery over time in the intervention group relative to TAU. CONCLUSIONS: According to the OQ-45, this psychosocial post-discharge intervention revealed an unintended negative effect on self-reported recovery over time. Specifically, the meeting of significant network members related to a moderate deteriorating effect, suggesting that the involvement of some carers, relatives, or friends may cause harm to the patient. Considering with reservation pending replication, these findings could have important implications for brief interventions targeted at patients' social networks. FUNDING: This study was supported by a private foundation. TRIAL REGISTRATION: ISRCTN58280620.

Predictors of burnout: results from a prospective community study.

The possible link between work strain and subsequent mental disorders has attracted public attention in many European countries. Burnout has become a favored concept within this context. Most burnout research has concentrated on various professional groups and less so on ordinary community samples. We analyzed the data collected from a 30-year community sample during seven measuring occasions, beginning in 1978. In the last assessment (2008), we included for the first time the Maslach Burnout Inventory (MBI). Making the diagnosis of a lifetime mental disorder a predictor for burnout required us to compile the cumulative prevalence rate over all seven occasions. We also evaluated various psycho-social predictors of burnout over the life cycle of our sample. Concurrent associations of the MBI with subscales from the SCL-90-R were also investigated. The relationship of burnout with several SCL-90-R subscales demonstrated that, in all dimensions, burnout is associated with significant psychopathology. Persons with a lifetime mood disorder, and especially those with a combination of mood and anxiety disorders, had a higher risk for subsequent burnout. Various partnership problems were another predictor for burnout. In conclusion, the role of mental disorder as an occupational illness remains controversial. Various forms of such disorders as well as some psycho-social predictors can predispose to burnout. By contrast, work-related predictors appear to be less important.

Comparing two basic subtypes in OCD across three large community samples: a pure compulsive versus a mixed obsessive-compulsive subtype.

Due to its heterogeneous phenomenology, obsessive-compulsive disorder (OCD) has been subtyped. However, these subtypes are not mutually exclusive. This study presents an alternative subtyping approach by deriving non-overlapping OCD subtypes. A pure compulsive and a mixed obsessive-compulsive subtype (including subjects manifesting obsessions with/without compulsions) were analyzed with respect to a broad pattern of psychosocial risk factors and comorbid syndromes/diagnoses in three representative Swiss community samples: the Zurich Study (n = 591), the ZInEP sample (n = 1500), and the PsyCoLaus sample (n = 3720). A selection of comorbidities was examined in a pooled database. Odds ratios were derived from logistic regressions and, in the analysis of pooled data, multilevel models. The pure compulsive subtype showed a lower age of onset and was characterized by few associations with psychosocial risk factors. The higher social popularity of the pure compulsive subjects and their families was remarkable. Comorbidities within the pure compulsive subtype were mainly restricted to phobias. In contrast, the mixed obsessive-compulsive subtype had a higher prevalence and was associated with various childhood adversities, more familial burden, and numerous comorbid disorders, including disorders characterized by high impulsivity. The current comparison study across three representative community surveys presented two basic, distinct OCD subtypes associated with differing psychosocial impairment. Such highly specific subtypes offer the opportunity to learn about pathophysiological mechanisms specifically involved in OCD.

Dyspareunia in the Context of Psychopathology, Personality Traits, and Coping Resources: Results From a Prospective Longitudinal Cohort Study From Age 30 to 50.

Although dyspareunia has a major impact on sexual and general wellbeing, there are few data on the longitudinal development of its prevalence in representative study groups. Therefore, it was the aim of the present study to fill this gap by evaluating the prevalence of dyspareunia in a representative sample at age 30, 35, 41, and 50. Additional aims were to determine the association between dyspareunia, psychopathological covariates, personality characteristics, and coping resources. Semi-structured interviews with single-item questions on sexual problems in general as well as dyspareunia were used to gain information on 1-year as well as long-time prevalence rates. Psychopathological covariates were explored with the SCL-90-R. The Freiburger Personality Inventory (Freiburger Persönlichkeits Inventar, FPI) assessed personality characteristics. Scales of sense of mastery and self-esteem were used to investigate coping resources. Twelve months prevalence of dyspareunia varied between 4.5 and 6.4 % with a mean of 5.6 % and a long-time risk of 19.3 %. No relation between age and the prevalence rates was found. Dyspareunia was related to psychopathological covariates, especially depression. With respect to personality traits as measured with the FPI only nervousness showed a significant association with dyspareunia, whereas coping resources were unrelated. As dyspareunia is experienced by about 20 % of all women, it represents a frequent sexual problem. Therefore, assessment of dyspareunia should be integrated into primary care of women at any age and diagnostic as well as therapeutic strategies should be based on physiological and psychological factors.
