Assisted dying is a contentious and topical issue. Mental disorder is a relevant influence on requests of hastened death. The psychiatry of dying is not a prominent component in the assessment of euthanasia and physician-assisted suicide (PAS) in jurisdictions with liberalised assisted dying laws. The literature on the assessment processes, with particular reference to mental status, involved in euthanasia requests is considered.

An experienced palliative medicine specialist and psychiatrist selectively reviewed the recent literature published about the mental health issues involved in euthanasia and PAS.

Assessments of competency, sustained wish to die prematurely, depressive disorder, demoralisation and ‘unbearable suffering’ in the terminally ill are clinically uncertain and difficult tasks. There is a growing psychiatric and psychological literature on the mental status of the terminally ill. As yet psychiatry does not have the expertise to ‘select’ those whose wish for hastened death is rational, humane and ‘healthy’. Rarely in those societies with liberalised assisted dying laws are psychiatrists involved in the decision-making for individuals requesting early death. This role is fulfilled by non-specialists.

There remain significant concerns about the accuracy of psychiatric assessment in the terminally ill. Mental processes are more relevant influences on a hastened wish to die than are the physical symptoms of terminal malignant disease. Psychiatric review of persons requesting euthanasia is relevant. It is not obligatory or emphasised in those legislations allowing assisted dying. Psychiatry needs to play a greater role in the assessment processes of euthanasia and PAS.

There is a reciprocal association between major depressive disorder (MDD) and coronary heart disease (CHD). These conditions are linked by a causal network of mechanisms. This causal network should be quantitatively studied and it is hypothesised that the investigation of vagal function represents a promising starting point. Heart rate variability (HRV) has been used to investigate cardiac vagal control in the context of MDD and CHD. This review aims to examine the relationship of HRV to both MDD and CHD in the context of vagal function and to make recommendations for clinical practice and research.

The search terms ‘heart rate variability’, ‘depression’ and ‘heart disease’ were entered into an electronic multiple database search engine. Abstracts were screened for their relevance and articles were individually selected and collated.

Decreased HRV is found in both MDD and CHD. Both diseases are theorised to disrupt autonomic control feedback loops on the heart and are linked to vagal function. Existing theories link vagal function to both mood and emotion as well as cardiac function. However, several factors can potentially confound HRV measures and would thus impact on a complete understanding of vagal mechanisms in the link between MDD and CHD.

The quantitative investigation of vagal function using HRV represents a reasonable starting point in the study of the relationship between MDD and CHD. Many psychotropic and cardiac medications have effects on HRV, which may have clinical importance. Future studies of HRV in MDD and CHD should consider antidepressant medication, as well as anxiety, as potential confounders.

This paper examines public attitudes towards the acceptability of using prescription drugs to treat depression and attention deficit hyperactivity disorder (ADHD), and whether attitudes are influenced by familiarity with the use of pharmacological treatments for these disorders.

Participants were 1265 members of the general public aged 18–101 years (50% female) participating in the Queensland Social Survey (QSS), an omnibus state-wide survey of households in the state of Queensland. The survey was administered through a CATI (computer-assisted telephone interviewing) system.

Most members of the public thought that the drug treatment of depression was acceptable (55%) but attitudes were much less positive towards the use of drugs to treat ADHD (35.6% acceptable). Regression analyses showed that respondents who knew someone who had received pharmacological treatment for depression were more likely to find it acceptable. However, participants were divided about the acceptability of drug treatment for ADHD regardless of whether they knew someone who had received drug treatment for ADHD or not. Participants with a higher level of education were more likely to find drug treatment for depression and ADHD acceptable. Participants who did not know anyone who had received drug treatment were less likely to have a definite opinion on whether it was acceptable or unacceptable.

Attitudes towards the acceptability of the use of prescription drugs are more positive for depression than for ADHD. This may broadly reflect ongoing controversies in the public sphere about the potential over-diagnosis of ADHD or overmedication of children with ADHD. Members of the public who do not know anyone with depression or ADHD may need particular information from prescribers in the event that they (or their child) are diagnosed.

Regular physical activity may be an important contributor to psychological well-being. This link has not been explored in ethnically distinct, low- and middle-income countries (LMIC), especially in countries affected by war. This study aimed to examine the relationship between physical activity and levels of psychological distress in an epidemiological cross-representative sample of Vietnamese living in the Mekong Delta region of Vietnam.

The sample was drawn from an urban (Cần Thơ City) and a rural (Hậ u Giang) region, using a multi-stage probabilistic cluster sampling frame. The measures applied included the Composite International Diagnostic Interview (CIDI 2.0) yielding 12-month prevalence rates of common mental disorders, including anxiety, mood and substance use disorders; the Phan Vietnamese Psychiatric Scale (PVPS), a culturally specific self-report measure; and the Harvard Trauma Questionnaire. The Global Physical Activity Questionnaire (GPAQ version 1) was used to measure activity. Analyses were conducted using SAS software v.9.1.3. The population was assigned to three (high, moderate and low) physical activity levels. Analyses included chi-square tests and univariable and multivariable logistic models.

Physical activity was greater in males, the middle-aged group (30–54 years), those who were married, the rural population, less educated individuals and those who were employed. High physical activity was significantly associated with low levels of psychological distress (indexed by a combination of CIDI and PVPS cases identified) when controlling for socio-demographic factors and number of medical conditions). Membership of the lowest of the three physical activity groups was associated with a psychological distress odds ratio of 2.19 (95% CI 1.28–3.75). The results remained consistent when analyses were undertaken separately for males and females.

Low levels of physical activity appear to be associated with greater psychological distress in the Mekong Delta of Vietnam. The association remained after adjusting for the influence of socio-demographic characteristics, exposure to past trauma, urban–rural residency and the presence of self-reported physical disorders. These data provide a foundation for exploring the role of physical activity as an adjunct to conventional interventions for common mental disorders in resource-poor LMIC countries.

Few studies of neuropsychological function in major depression have examined emotional processing or the impact of gender. Patients have also been compared with highly selected control participants and rarely with other patient groups. The objective of this study was to compare neuropsychological function in a major depressive episode (MDE) with a group of patients with an anxiety disorder, social anxiety disorder (SAD), and healthy controls, to include measures of emotional processing and to analyse the effects of gender on neuropsychological function and emotional processing in these groups.

One hundred and one medication-free patients with MDE, 30 patients with SAD and 76 healthy control participants were recruited. The groups were matched for age and estimated premorbid intelligence and education. Subjects performed a battery of neuropsychological tests assessing; verbal learning and memory, visuospatial learning and memory, attention, executive function and psychomotor performance. They also performed a task measuring the accuracy of recognition of facial emotional expressions.

Compared with healthy participants and those with SAD, patients with MDE were significantly impaired in verbal learning and spatial working memory. The SAD group misclassified significantly more neutral expressions as angry and fewer as sad, compared with the MDE group and healthy controls, but there were no significant differences between the MDE group and healthy controls. The profile of performance was the same regardless of gender.

The study confirms a significant impairment in neuropsychological function in a clinical sample of outpatients with MDE, which is likely to have important implications for day-to-day functioning and treatment.

To derive planning estimates for the provision of public mental health services in Queensland 2007–2017.

We used a five-step approach that involved: (i) estimating the prevalence and severity of mental disorders in Queensland, and the number of people at each level of severity treated by health services; (ii) benchmarking the level and mix of specialised mental health services in Queensland against national data; (iii) examining 5-year trends in Queensland public sector mental health service utilisation; (iv) reviewing Australian and international planning benchmarks; and (v) setting resource targets based on the results of the preceding four steps. Best available evidence was used where possible, supplemented by value judgements as required.

Recommended resource targets for inpatient service were: 20 acute beds per 100,000 population, consistent with national average service provision but 13% above Queensland provision in 2005; and 10 non-acute beds per 100,000, 65% below Queensland levels in 2005. Growth in service provision was recommended for all other components. Adult residential rehabilitation service targets were 10 clinical 24-hour staffed beds per 100,000, and 18 non-clinical beds per 100,000. Supported accommodation targets were 35 beds per 100,000 in supervised hostels and 35 places per 100,000 in supported public housing. A direct care clinical workforce of 70 FTE per 100,000 for ambulatory care services was recommended. Fifteen per cent of total mental health funding was recommended for community support services provided by non-government organisations.

The recommended targets pointed to specific areas for priority in Queensland, notably the need for additional acute inpatient services for older persons and expansion of clinical ambulatory care, residential rehabilitation and supported accommodation services. The development of nationally agreed planning targets for public mental health services and the mental health community support sector were identified as priorities.

The present study seeks to examine the impact of therapeutic interventions for people from refugee backgrounds within a naturalistic setting.

Sixty-two refugees from Burma were assessed soon after arriving in Australia. All participants received standard interventions provided by a resettlement organisation which included therapeutic interventions, assessment, social assistance, and referrals where appropriate. At the completion of service provision a follow-up assessment was conducted.

Over the course of the intervention, participants experienced a significant decrease in symptoms of post-traumatic stress disorder, anxiety, depression and somatisation. Pre-intervention symptoms predicted symptoms post-intervention for post-traumatic stress, anxiety and somatisation. Post-migration living difficulties, the number of traumas experienced, and the number of contacts with the service agency were unrelated to all mental health outcomes.

In the first Australian study of its kind, reductions in mental health symptoms post-intervention were significantly linked to pre-intervention symptomatology and the number of therapy sessions predicted post-intervention symptoms of post-traumatic stress. Future studies need to include larger samples and control groups to verify findings.
