Post-traumatic stress disorder (PTSD) is typically associated with high-risk population groups, but the risk of PTSD that is associated with trauma experienced in the community, and effect of changes in diagnostic criteria in DSM-5 on prevalence in the general population, is unknown.

Cross-sectional analysis of population-based data from 4558 adults aged 25–83 years resident in Caerphilly county borough, Wales, UK. Exposure to different traumatic events was assessed using categorisation of free-text descriptions of trauma. PTSD caseness was determined using items assessing Diagnostic and Statistical Manual IV (DSM-IV) and DSM-5 A criteria and the Traumatic Screening Questionnaire.

Of the 4558 participants, 1971 (47.0%) reported a traumatic event. The most common DSM-IV A1 qualifying trauma was life-threatening illnesses and injuries (13.6%). The highest risk of PTSD was associated with assaultive violence [34.1%]. The prevalence of PTSD using DSM-IV A criteria was 14.3% (95% confidence interval [CI] = 12.8, 15.9%). Using DSM-5 A criteria reduced the prevalence to 8.0 (95% CI = 6.9, 9.4%), primarily due to exclusion of DSM-IV A1 qualifying events, such as life-threatening illnesses.

Nearly one-half of a general community sample had experienced a traumatic event and of these around one in seven was a DSM-IV case of PTSD. Although the majority of research has concentrated on combat, rape and assaultive violence, life threatening illness is a more common cause of PTSD in the community. Removal of this traumatic event in DSM-5 could reduce the number of cases of PTSD by around 6.0%.

This study builds on existing research on the prevalence and consequences of mental illness discrimination by investigating and quantifying the relationships between experienced discrimination and costs of healthcare and leisure activities/social participation among secondary mental health service users in England.

We use data from the Mental Illness-Related Investigations on Discrimination (MIRIAD) study (n = 202) and a subsample of the Viewpoint study (n = 190). We examine experiences of discrimination due to mental illness in the domains of personal relationships, community activities, and health care, and how such experienced discrimination relates to patterns of service use and engagement in leisure activities.

Our findings show that the cost of health services used for individuals who reported previous experiences of discrimination in a healthcare setting was almost twice as high as for those who did not report any discrimination during the last 12 months (Relative Risk: 1.73; 95% Confidence Interval (CI): 1.39, 2.17) and this was maintained after controlling for symptoms and functioning. Experienced discrimination in healthcare (Relative Risk: 0.83; 95% CI: 0.81, 0.84) or in relationships (Relative Risk: 0.89; 95% CI: 0.87, 0.91), however, was associated with lower participation in, and hence lower costs of, leisure activities. Individuals who reported any discrimination in a healthcare setting had, on average, £434 higher costs associated with health service use while reported discrimination in the community was associated with increased leisure costs of £32.

These findings make an important initial step towards understanding the magnitude of the costs of mental health-related discrimination.

To test the hypothesis that cognitive impairment in older adults is associated with all-cause mortality risk and the risk increases when the degree of cognitive impairment augments; and then, if this association is confirmed, to report the population-attributable fraction (PAF) of mortality due to cognitive impairment.

A representative random community sample of individuals aged over 55 was interviewed, and 4557 subjects remaining alive at the end of the first year of follow-up were included in the analysis. Instruments used in the assessment included the Mini-Mental Status Examination (MMSE), the History and Aetiology Schedule (HAS) and the Geriatric Mental State (GMS)-AGECAT. For the standardised degree of cognitive impairment Perneczky et al's MMSE criteria were applied. Mortality information was obtained from the official population registry. Multivariate Cox proportional hazard models were used to test the association between MMSE degrees of cognitive impairment and mortality risk. We also estimated the PAF of mortality due to specific MMSE stages.

Cognitive impairment was associated with mortality risk, the risk increasing in parallel with the degree of cognitive impairment (Hazard ratio, HR: 1.18 in the ‘mild’ degree of impairment; HR: 1.29 in the ‘moderate’ degree; and HR: 2.08 in the ‘severe’ degree). The PAF of mortality due to severe cognitive impairment was 3.49%.

A gradient of increased mortality-risk associated with severity of cognitive impairment was observed. The results support the claim that routine assessment of cognitive function in older adults should be considered in clinical practice.

Prevalence and covariates of subclinical psychosis have gained increased interest in the context of early identification and treatment of persons at risk for psychosis.

We analysed 9829 adults representative of the general population within the canton of Zurich, Switzerland. Two psychosis syndromes, derived from the SCL-90-R, were applied: ‘schizotypal signs’ and ‘schizophrenia nuclear symptoms’.

Only a few subjects (13.2%) reported no schizotypal signs. While 33.2% of subjects indicated mild signs, only a small proportion (3.7%) reported severe signs. A very common outcome was no ‘schizophrenia nuclear symptoms’ (70.6%). Although 13.5% of the participants reported mild symptoms, severe nuclear symptoms were very rare (0.5%). Because these two syndromes were only moderately correlated (r = 0.43), we were able to establish sufficiently distinct symptom clusters. Schizotypal signs were more closely connected to distress than was schizophrenia nuclear symptoms, even though their distribution types were similar. Both syndromes were associated with several covariates, such as alcohol and tobacco use, being unmarried, low education level, psychopathological distress and low subjective well-being.

Subclinical psychosis symptoms are quite frequent in the general population but, for the most part, are not very pronounced. In particular, our data support the notion of a continuous Wald distribution of psychotic symptoms in the general population. Our findings have enabled us to confirm the usefulness of these syndromes as previously assessed in other independent community samples. Both can appropriately be associated with well-known risk factors of schizophrenia.

This study evaluated the measurement invariance of the strengths and difficulties questionnaire (SDQ) self-report among adolescents from seven different nations.

Data for 2367 adolescents, aged 13–18 years, from India, Indonesia, Nigeria, Serbia, Turkey, Bulgaria and Croatia were available for a series of factor analyses.

The five-factor model including original SDQ scales emotional symptoms, conduct problems, hyperactivity–inattention problems, peer problems and prosocial behaviour generated inadequate fit degree in all countries. A bifactor model with three factors (i.e., externalising, internalising and prosocial) and one general problem factor yielded adequate degree of fit in India, Nigeria, Turkey and Croatia. The prosocial behaviour, emotional symptoms and conduct problems factor were found to be common for all nations. However, originally proposed items loaded saliently on other factors besides the proposed ones or only some of them corresponded to proposed factors in all seven countries.

Due to the lack of a common acceptable model across all countries, namely the same numbers of factors (i.e., dimensional invariance), it was not possible to perform the metric and scalar invariance test, what indicates that the SDQ self-report models tested lack appropriate measurement invariance across adolescents from these seven nations and it needs to be revised for cross-country comparisons.

Considerable evidence now links childhood adversity to a variety of adult health problems. Unfortunately, almost all of these studies have relied upon retrospective assessment of childhood events, creating a vulnerability to bias. In this study, we sought to examine three associations using data sources that allowed for both prospective and retrospective assessment of childhood events.

Methods. A 1994 national survey of children between the ages of 0 and 11 collected data from a ‘person most knowledgeable’ (usually the mother) about a child. It was possible to link data for n = 1977 of these respondents to data collected from the same people in a subsequent adult study. The latter survey included retrospective reports of childhood adversity. We examined three adult health outcomes in relation to prospectively and retrospectively assessed childhood adversity: major depressive episodes, excessive alcohol consumption and painful conditions.

Results. A strong association between childhood adversities (as assessed by both retrospective and prospective methods) and major depression was identified although the association with retrospective assessment was stronger. Weaker associations were found for painful conditions, but these did not depend on the method of assessment. Associations were not found for excessive alcohol consumption irrespective of the method of assessment.

These findings help to allay concerns that associations between childhood adversities and health outcomes during adulthood are merely artefacts of recall bias. In this study, retrospective and prospective assessment strategies produced similar results.

A range of peer worker roles are being introduced into mental health services internationally. There is some evidence that attests to the benefits of peer workers for the people they support but formal trial evidence in inconclusive, in part because the change model underpinning peer support-based interventions is underdeveloped. Complex intervention evaluation guidance suggests that understandings of how an intervention is associated with change in outcomes should be modelled, theoretically and empirically, before the intervention can be robustly evaluated. This paper aims to model the change mechanisms underlying peer worker interventions.

In a qualitative, comparative case study of ten peer worker initiatives in statutory and voluntary sector mental health services in England in-depth interviews were carried out with 71 peer workers, service users, staff and managers, exploring their experiences of peer working. Using a Grounded Theory approach we identified core processes within the peer worker role that were productive of change for service users supported by peer workers.

Key change mechanisms were: (i) building trusting relationships based on shared lived experience; (ii) role-modelling individual recovery and living well with mental health problems; (iii) engaging service users with mental health services and the community. Mechanisms could be further explained by theoretical literature on role-modelling and relationship in mental health services. We were able to model process and downstream outcomes potentially associated with peer worker interventions.

An empirically and theoretically grounded change model can be articulated that usefully informs the development, evaluation and planning of peer worker interventions.

To explore the role of psychiatric admission, diagnosis and reported unfair treatment in the relationship between ethnicity and mistrust of mental health services.

The Mental Illness-Related Investigations on Discrimination (MIRIAD) study was a cross-sectional study of 202 individuals using secondary mental health services in South London. Two structural equation models were estimated, one using Admission (whether admitted to hospital for psychiatric treatment in the past 5 years) and one using involuntary admission to hospital in the past 5 years.

Increased mistrust was directly associated with the latent variable ‘unfair treatment by mental health services and staff’ and with Black or mixed ethnicity in both models. Those with a diagnosis of schizophrenia spectrum (as compared to depression and bipolar disorder) had a lower average score on the latent variable, suggesting that on average they reported less unfair treatment. We found evidence of increased reporting of unfair treatment by those who had an admission in the past 5 years, had experienced involuntary admission, and for people of Black of mixed Black and White ethnicity.

Neither prevalence of schizophrenia spectrum nor rates of hospital admission explained the greater mistrust of mental health services found among people of Black and mixed Black and White ethnicity compared with White ethnicity. Rather, people of Black and mixed Black and white ethnicity may be more likely to experience unfair treatment, generating mistrust; furthermore, this group is more likely to express mistrust even after accounting for reporting of unfair treatment by mental health services and staff.

New reimbursement schemes for inpatient mental health care are imminent in the UK and Germany. The shared intention is to reflect cost differences between patients in reimbursement rates. This requires understanding of patient characteristics that influence hospital resource use. The aim of this review was to show which associations between mental health care per diem hospital costs and patient characteristics are supported by current evidence.

A systematic review of the literature published between 1980 and 2012 was carried out. The search strategy included electronic databases and hand-searching. Furthermore, reference lists, citing articles and related publications were screened and experts were contacted.

The search found eight studies. Dispersion in per diem costs was moderate, as was the ability to explain it with patient characteristics. Six patient characteristics were identified as the most relevant variables. These were (1) age, (2) major diagnostic group, (3) risk, (4) legal problems, (5) the ability to perform activities of daily living and (6) presence of psychotic or affective symptoms. Two non-patient-related factors were identified. These were (1) day of stay and (2) treatment site.

Idiosyncrasies of mental health care complicated the prediction of per diem hospital costs. More research is required in European settings since transferability of results is unlikely.

This paper aims to present the Integrated Atlas of Mental Health of Catalonia (2010) focusing on: (a) the importance of using a taxonomy-based coding and standard system of data collection when assessing health services; and (b) its relevance as a tool for evidence-informed policy.

This study maps all the care-related services for people with mental disorders available in Catalonia in 2010, using the ‘Description and Evaluation of Services and Directories in Europe for long-term care’ (DESDE-LTC). The unit of analysis is the Basic Stable Input of Care (BSIC), which is the minimal organisation unit composed by a set of inputs with temporal stability. We presented data on: (a) availability of BSICs and their capacity; (b) the adequacy of the provision of care, taking into account availability and accessibility; (c) the evolution of BSCIs from 2002 to 2010; and (d) the perceived relevance of Atlas of Mental Health as a tool for evidence-informed policy.

We identified a total of 639 BSICs. A lack of Health services was detected in highly rural areas, although there was moderate availability of Social Services. Overall, more than 80% of the small mental health areas in Catalonia had an adequate core mental health service. Since 2002 the availability of mental health services has increased. Decision makers found the Atlas a useful and relevant tool for evidence informed policy.

Policy makers can use Atlases to detect gaps and inequities in the provision of care for people with mental health needs.

There is substantial diversity in national suicide rates, which has mainly been related to socio-economic factors, as well as cultural factors. Stigma is a cultural phenomenon, determining the level of social acceptance or rejection of persons with mental illness in a society. In this study, we explore whether national suicide rates are related to the degree of mental illness stigma in that country.

We combine the data on country-level social acceptance (Eurobarometer) with the data on suicide rates and socio-economic indicators (Eurostat) for 25 European countries.

In a linear regression model controlling for socio-economic indicators, the social acceptance of someone with a significant mental health problem in 2010 was negatively correlated with age standardised national suicide rates in the same year (β −0.46, p = 0.014). This association also held true when combining national suicide rates with death rates due to events of undetermined intent.

Stigma towards persons with mental health problems may contribute to differences in suicide rates in a country. We hypothesise possible mechanisms explaining this link, including stigma as a stressor and social isolation as a consequence of stigma.

Previous population-based studies did not support the view that biological and genetic causal models help increase social acceptance of people with mental illness. However, practically all these studies used un-labelled vignettes depicting symptoms of the disorders of interest. Thus, in these studies the public's reactions to pathological behaviour had been assessed rather than reactions to psychiatric disorders that had explicitly been labelled as such. The question arises as to whether results would have been similar if respondents had been confronted with vignettes with explicit mention of the respective diagnosis.

Analyses are based on data of a telephone survey in two German metropolises conducted in 2011. Case-vignettes with typical symptoms suggestive of depression or schizophrenia were presented to the respondents. After presentation of the vignette respondents were informed about the diagnosis.

We found a statistically significant association of the endorsement of brain disease as a cause with greater desire for social distance from persons with schizophrenia. In major depression, this relation was absent. With both disorders, there was no statistically significant association between the endorsement of hereditary factors as a cause and social distance.

Irrespective of whether unlabelled or labelled vignettes are employed, the ascription to biological or genetic causes seems not to be associated with a reduction of the public's desire for social distance from people with schizophrenia or depression. Our results corroborate the notion that promulgating biological and genetic causal models may not help decrease the stigma surrounding these illnesses.

The relative importance of traumatic events (TEs) in accounting for the social burden of post-traumatic stress disorder (PTSD) could vary according to cross-cultural factors. In that sense, no such studies have yet been conducted in the Spanish general population. The present study aims to determine the epidemiology of trauma and PTSD in a Spanish community sample using the randomly selected TEs method.

The European Study of the Epidemiology of Mental Disorders (ESEMeD)-Spain is a cross-sectional household survey of a representative sample of adult population. Lifetime prevalence of self-reported TEs and lifetime and 12-month prevalence of PTSD were evaluated using the World Health Organization (WHO) Composite International Diagnostic Interview. Reports of PTSD associated with randomly selected TEs were weighted by the individual-level probabilities of TE selection to generate estimates of population-level PTSD risk associated with each TE.

Road accident was the most commonly self-reported TE (14.1%). Sexual assault had the highest conditional risk of PTSD (16.5%). The TEs that contributed most to societal PTSD burden were unexpected death of a loved one (36.4% of all cases) and sexual assault (17.2%). Being female and having a low educational level were associated with low risk of overall TE exposure and being previously married was related to higher risk. Being female was related to high risk of PTSD after experiencing a TE.

Having an accident is commonly reported among Spanish adults, but two TE are responsible for the highest burden associated with PTSD: the unexpected death of someone close and sexual assault. These results can help designing public health interventions to reduce the societal PTSD burden.

Acute psychiatric provision in the UK today as well as globally has many critics including service users and nurses.

Four focus groups, each meeting twice, were held separately for service users and nurses. The analysis was not purely inductive but driven by concerns with the social position of marginalised groups – both patients and staff.

The main themes were nurse/patient interaction and coercion. Service users and nurses conceptualised these differently. Service users found nurses inaccessible and uncaring, whereas nurses also felt powerless because their working life was dominated by administration. Nurses saw coercive situations as a reasonable response to factors ‘internal’ to the patient whereas for service users they were driven to extreme behaviour by the environment of the ward and coercive interventions were unnecessary and heavy handed.

This study sheds new light on living and working in acute mental health settings today by comparing the perceptions of service users and nurses and deploying service user and nurse researchers. The intention is to promote better practice by providing a window on the perceptions of both groups.

The rate with which attention deficit/hyperactivity disorder (ADHD) is diagnosed varies widely across countries, suggesting that cultural factors influence the clinical interpretation of child behaviour. This study estimated the point prevalence of severe ADHD among elementary and middle-school Italian children.

An epidemiological sample of 2016 children attending 2nd–8th grade in the Italian regions of Tuscany and Latium was selected based on census distribution of the school-age population. Teachers completed the Italian version of the ADHD Rating Scale for Teachers (SDAI). For children with at least six inattention symptoms and/or at least six hyperactivity/impulsivity symptoms rated ‘very often’ by the teachers, the parents completed the Italian ADHD Rating Scale for Parents (SDAG). Children with documented ADHD symptoms at both school and home received a complete psychiatric interview with the Kiddie Schedule for Affective Disorders and Schizophrenia-present and lifetime version (K-SADS-PL).

Of the 1887 assessed children, 4.45% (95% CI 3.58–5.51) met the ADHD cut-off on teacher ratings, 1.43% (0.96–2.12) had ADHD symptoms endorsed by both teacher and parent, and 1.32% (0.87–1.97) were further confirmed by the psychiatric evaluation. The male:female ratio was 7:1. The inattentive type accounted for about half of the ADHD cases.

When applying stringent criteria for both severity and pervasiveness of symptoms, it is estimated that about 1.3% of the Italian elementary and middle-school children suffer from severe ADHD.

Young adults with early psychosis want to pursue normal roles – education and employment. This paper summarises the empirical literature on the effectiveness of early intervention programmes for employment and education outcomes.

We conducted a systematic review of employment/education outcomes for early intervention programmes, distinguishing three programme types: (1) those providing supported employment, (2) those providing unspecified vocational services and (3) those without vocational services. We summarised findings for 28 studies.

Eleven studies evaluated early intervention programmes providing supported employment. In eight studies that reported employment outcomes separately from education outcomes, the employment rate during follow-up for supported employment patients was 49%, compared with 29% for patients receiving usual services. The two groups did not differ on enrolment in education. In four controlled studies, meta-analysis showed that the employment rate for supported employment participants was significantly higher than for control participants, odds ratio = 3.66 [1.93–6.93], p < 0.0001. Five studies (four descriptive and one quasi-experimental) of early intervention programmes evaluating unspecified vocational services were inconclusive. Twelve studies of early intervention programmes without vocational services were methodologically heterogeneous, using diverse methods for evaluating vocational/educational outcomes and precluding a satisfactory meta-analytic synthesis. Among studies with comparison groups, 7 of 11 (64%) reported significant vocational/education outcomes favouring early intervention over usual services.

In early intervention programmes, supported employment moderately increases employment rates but not rates of enrolment in education. These improvements are in addition to the modest effects early programmes alone have on vocational/educational outcomes compared with usual services.

To determine whether disparities exist in mental health care provision to immigrants and Italian citizens with severe mental illness in Bologna, Italy.

Records of prevalent cases on 31/12/2010 with severe mental illness and ≥1 contact with Community Mental Health Centers in 2011 were extracted from the mental health information system. Logistic and Poisson regressions were carried out to estimate the probability of receiving rehabilitation, residential or inpatient care, the intensity of outpatient treatments and the duration of hospitalisations and residential care for immigrant patients compared to Italians, adjusting for demographic and clinical covariates.

The study population included 8602 Italian and 388 immigrant patients. Immigrants were significantly younger, more likely to be married and living with people other than their original family and had a shorter duration of contact with mental health services. The percentages of patients receiving psychosocial rehabilitation, admitted to hospital wards or to residential facilities were similar between Italians and immigrants. The number of interventions was higher for Italians. Admissions to acute wards or residential facilities were significantly longer for Italians. Moreover, immigrants received significantly more group rehabilitation interventions, while more social support individual interventions were provided to Italians.

The probability of receiving any mental health intervention is similar between immigrants and Italians, but the number of interventions and the duration of admissions are lower for immigrants. Data from mental health information system should be integrated with qualitative data on unmet needs from the immigrants' perspective to inform mental health care programmes and policies.

Because no epidemiological study has been conducted of children's mental health problems in Kosova, which experienced a traumatic war in 1998–99, we conducted the first national epidemiological survey of children's mental health ever undertaken in Kosova.

Participants were 1374 Kosovar children ages 6–18 recruited through schools (60% from urban areas). Parent-reported behavioural and emotional problems were assessed using the Child Behaviour Checklist (CBCL/6–18). Kosovar findings were compared with findings from five other Central and Eastern European societies (Poland, Romania, Lithuania, Serbia and Croatia), plus the US.

Confirmatory factor analysis (CFA) indicated that the CBCL 8-syndrome model manifested good fit to the Kosovar data. Mean item ratings and Cronbach's alphas were very similar to those of the other six societies. Kosova's mean Total Problems score fell in the middle of the range of the seven societies compared. CBCL scores were higher for adolescents (12–18), urban children, and those whose parents had limited education compared with younger (6–11), rural, and more socially advantaged children.

Strong consistency was found between Kosovar findings and those for neighbouring countries with respect to CFA results, mean item ratings, alphas and problem score levels. Results of this epidemiological survey highlight the utility of the CBCL for identifying Kosovar Albanian children with mental health service needs.

The Camberwell Assessment of Need – Forensic Version (CANFOR) is a standardised assessment tool specifically designed to assess needs for care in forensic psychiatric populations. The original English version of the instrument has shown good psychometric properties. The aim of this study was to validate the Italian version of the CANFOR-staff tool.

After translation and back-translation, the Italian CANFOR tool was administered to a sample of 50 forensic psychiatric patients. Convergent validity was tested using the Brief Psychiatric Rating Scale (BPRS) and the Global Assessment of Functioning (GAF) by applying Kendall's tau-b. Inter-rater and test–retest reliabilities were measured by ICCs for need dimensions (total and unmet) and Cohen's kappa coefficients for individual need items.

Regarding convergent validity, a higher number of needs (total and unmet) were associated with more severe psychiatric symptoms (BPRS). Higher numbers of unmet needs were also associated with lower levels of global functioning (GAF). ICCs for total and unmet needs scores indicated a good level of agreement for inter-rater reliability and a very good level for test–retest, respectively. Regarding the specific items, inter-rater Cohen's kappa was high (moderate to very good agreement) for 18 items in relation to the presence of a need and for 15 items in the rating of an unmet need, whereas Cohen's kappa for test–retest reliability was very high for all the items in the presence of a need and high for 18 of the unmet need domains.

The Italian version of CANFOR has adequate psychometric properties. It can be considered a promising instrument for the assessment of needs of forensic psychiatric patients.

The links between migrant status and psychosis have attracted considerable attention in recent decades. The aim of the study was to explore the demographic and clinical correlates of migrant v. Australia-born status in individuals with psychotic disorders using a large community-based sample.

Data were drawn from a population-based prevalence survey of adults with psychotic disorders. Known as the Survey of High Impact Psychosis (SHIP), it was conducted in seven Australian catchment areas in 2010. Logistic regression was used for the main analyses, examining associations of migrant status with sociodemographic and clinical variables.

Of the 1825 participants with psychotic disorders, 17.8% (n = 325) were migrants, of whom 55.7% (n = 181) were male. Compared to Australia-born individuals with psychosis, migrants were more likely to be currently married, to have completed a higher level at school, to have left school later, and to be employed with full-time jobs. Migrants with psychosis were either no different from or less impaired or disadvantaged compared to their Australian-born counterparts on a range of clinical and demographic variables.

In a sample of individuals with psychotic disorders, there was no evidence to suggest that migrant status was associated with worse clinical or socio-economic outcomes compared to their native-born counterparts.
