Population-based research on mental disorders needs to keep pace with trends in general epidemiology. At present, this requirement is complicated by uncertainty within the parent discipline about its future development. The present study examines proposals for new directions in strategy and methods and considers their significance for psychiatric epidemiology.

Narrative review, cross-checked by search of English-language journals of epidemiology for new trends and developments reported in the years from 2000 onwards.

The proposals reviewed here are divided into three groups:

1. 1. A new research paradigm of ‘eco-epidemiology’, which includes both individual risk factors and macro-environmental systems that mediate population levels of health and sickness.

2. 2. Improved ‘translation’ of research findings – i.e. more rapid and effective implementation of epidemiological evidence into health policy and practice.

3. 3. Adaptation of epidemiology to a globalised economy, with firmer regulation of funding and resources.

Each of these proposals has implications for psychiatric epidemiology. Workers in this field, however, are still preoccupied by relatively specific problems of definition, measurement and classification, and so far the current debates in general epidemiology are scarcely reflected. The proposals outlined above call for:

• • a working model of eco-epidemiology as it relates to psychiatric disorders;

• • implementation strategies to encourage more active participation in epidemiological research by community health services and caregiver organisations;

• • international collaborative projects that offer practical benefits in training and service facilities for the countries taking part.

Discrimination against people with severe mental illness is an international problem. It is associated with reduced social contact and hinders recovery. This paper aims to evaluate if experienced or anticipated discrimination is associated with social capital, a known correlate of mental health.

Data from the annual viewpoint cross-sectional survey of people with severe mental illness (n = 1016) were analysed. Exploratory univariate analysis was used to identify correlates of social capital in the sample, which were then evaluated in linear regression models. Additional hypotheses were tested using t tests.

Experienced discrimination made a modest contribution to the explained variance of social capital. Experienced discrimination from friends and immediate family was associated with reduced access to social capital from these groups, but this was not found for wider family, neighbours or mental health staff. Experience of discrimination in finding or keeping a job was also associated with reduced access to social capital.

Further longitudinal research is needed to determine how resources within people's networks can help to build resilience, which reduces the harmful effect of discrimination on mental health.

To evaluate the effectiveness of a brief suicide management training programme for Japanese medical residents compared with the usual lecture on suicidality.

In this multi-center, clustered randomized controlled trial, the intervention group attended a structured suicide management programme and the control group, the usual lecture on depression and suicidality. The primary outcome was the difference in residents' cumulative competency score to manage suicidal persons from baseline (T0) to 1 month after the intervention (T2), determined using the Suicide Intervention Response Inventory (SIRI-1) score, at individual level.

Analysis of 114 residents (intervention group n = 65, control group n = 49) assigned to two clusters in each group revealed no change in SIRI-1 score from T0 to T2 or immediately after the intervention (T1) between the two groups. As a secondary analysis, discrepancy in judgement between the participants and Japanese suicidologists was examined immediately after the intervention in the adjusted model, with a mean difference in score of 9.98 (95% confidence interval: 4.39–15.56; p = 0.001).

The structured programme was not proven to improve competency in suicide management when measured by the SIRI-1 score. Further elaboration of the programme and valid measurement of its outcome would be needed to show the program's effectiveness.

To examine stigma- and knowledge-related barriers to help-seeking among members of the general population.

In a representative survey of young to middle-aged Swiss adults (n = 8875), shame about a potential own mental illness, perceived knowledge about and satisfaction with one's mental health, psychiatric symptoms and attitudes towards help-seeking were assessed.

A latent profile analysis of all participants yielded two groups with different attitudes towards help-seeking. Relative to the majority, a one-in-four subgroup endorsed more negative attitudes towards seeking professional help, including psychiatric medication, and was characterized by more shame, less perceived knowledge, higher satisfaction with their mental health, younger age, male gender and lower education. Among participants with high symptom levels (n = 855), a third subgroup was reluctant to seek help in their private environment and characterized by high symptoms as well as low satisfaction with their mental health.

Shame as an emotional proxy of self-stigma as well as poor subjective mental health literacy may be independent barriers to help-seeking. Interventions to increase mental health service use could focus on both variables and on those individuals with more negative views about professional help, in the general public as well as among people with a current mental illness.

To assess the extent to which being a victim of intimate partner violence (IPV) is associated with psychiatric disorders in men and women.

A stratified multistage random sample was used in the third English psychiatric morbidity survey. Psychiatric disorders were measured by the Clinical Interview Schedule (Revised) and screening questionnaires. IPV was measured using British Crime Survey questions.

18.7% (95% CI 17.1–20.4; n = 595 of 3197) of men had experienced some form of IPV compared with 27.8% of women (95% CI 26.2–29.4; n = 1227 of 4206; p < 0.001). IPV was associated with all disorders measured (except eating disorders in men). Physical IPV was significantly linked to psychosis and with substance and alcohol disorders in men and women, but significant associations with common mental disorders (CMDs), post-traumatic stress disorder (PTSD) and eating disorders were restricted to women. Emotional IPV was associated with CMDs in men and women.

The high prevalence of experiences of partner violence, and strength of the association with every disorder assessed, suggests enquiry about partner violence is important in identifying a potential risk and maintenance factor for psychiatric disorders, and to ascertain safety, particularly in women as they are at greatest risk of being victims of violence.

Depression requires the presence of either depressed mood or anhedonia, yet little research attention has been focused on distinguishing these two symptoms. This study aimed to obtain the prevalence rates of these two core depression symptoms and to explore the risk factors for each symptom by race/ethnicity.

2423 White, African American, Hispanic and Asian/Pacific Islander (API) women from the Massachusetts area completed the Pregnancy Risk Assessment Monitoring System (PRAMS) from 2007 to 2008.

Socioeconomic variables (SES) accounted for increased rates in depressed mood and anhedonia among African Americans and Hispanics compared with Whites. API women were still 2.1 times more likely to report anhedonia after controlling for SES. Stressors were associated with depressed mood across groups and associated with anhedonia for Whites and Hispanics. Having a female infant was associated with depressed mood for APIs. Being non-US born was associated with anhedonia for Whites, APIs and African Americans, but not Hispanics.

Prevalence rates for depressed mood and anhedonia differ across race/ethnic groups and risks associated with depressed mood and anhedonia depend on the race/ethnic group, suggesting the importance of distinguishing depressed mood from anhedonia in depression assessment and careful inquiry regarding symptom experiences with a diverse patient population.
