The article comments on the primary papers from Te Rau Hinengaro, the New Zealand mental health survey. It states that there are more useful myths than scientific facts based on the eleven reports related to mental health survey and research. It mentions that mental illness is associated with much more over-reporting than under-reporting of treatment.

The new RANZCP guidelines for the treatment of schizophrenia and related disorders highlights what we know works. In this paper, we examine why patients so often fail to benefit from this knowledge and why clinical practice falls so far short of the recommended standard. Instead of the continuous improvement that we expect of health care in general, in psychiatry we face an accelerating decline in systems of care. There has been a sustained underinvestment in public mental health care and a shared failure by State and Federal governments to construct and commit to a governance and funding model that can deliver the standard of care that is available in other major non-communicable diseases, and which we know is equally possible for severe mental illness. This paper sets out some of the reasons for the poor quality of care received by many people with schizophrenia and related disorders in Australia, and describes ways that care could be improved. In particular, we recommend an explicit statement of what constitutes an adequate standard of care, for people at all stages of these illnesses. This would help provide transparency about whether the care provided by mental health services achieves these benchmarks, and enable publication of results comparing the performance of different states and regional services. Patients and families, as well as professional, consumer and carer organizations would then be able to see clearly where the deficits are and demand resources and care that match the recommendations.

Objective: In New Zealand and Australia, a renewed emphasis on equity and efficiency in the provision of mental health care has seen outcomes-focused, culturally appropriate clinical practice become essential within mental health services. Ascertaining the degree to which quality improvement and monitoring systems are enhancing professional practice and patient outcomes, however, is hindered by the difficulty of measuring the process of quality care delivery. Method: This paper argues that it is the process of care delivery (i.e. what clinicians do to, and for, patients) that is critical to the effectiveness of treatment and the degree to which treatment either inhibits or promotes an improvement in mental health recovery. Identification of the underlying causes of poor achievement of process factors is likely to positively impact on things such as readmission rates, shared care initiatives, and ultimately patient recovery. Such attention could be the difference between low-quality service provision and a high-quality service provision with positive recovery outcomes for patients. Results: Ascertaining the degree to which quality improvement and monitoring systems are enhancing professional practice and patient outcomes for indigenous people, however, is hindered by the difficulty of measuring such concepts. Australia has indeed embraced 'culturally appropriate' practice in recent years, but this appears to be piecemeal when compared with New Zealand. Certainly, there are inconsistent and variable approaches to cultural practices with indigenous people when comparing the two countries. Conclusions: Using evidence from a bicultural mental health nursing study that developed and validated generic and Maori-specific (indigenous) clinical indicators for mental health nursing standards of practice in New Zealand, it is argued that the process of care delivery is equally as important as outcome measures when ascertaining the effectiveness of nursing care. Second, this paper contends that accurate process measures must be culturally responsive to indigenous and other ethnic groups. [ABSTRACT FROM AUTHOR]

Objective: This paper provides an overview of the Christchurch Health and Development Study (CHDS) and a summary of findings relating to child and adolescent mental health. Method: The CHDS is a longitudinal study of a birth cohort of 1265 children born in the Christchurch (New Zealand) urban region during mid 1977. This cohort has now been studied from birth to age 21. Results: The paper examines the ways in which the study has been able to examine a wide range of issues. Key issues examined include: (i) measurement of disorder (respondent effects; dimensionality; scales vs categories); (ii) prevalence and treatment of disorder; (iii) stability and continuity of disorders; (iv) the contribution of risk and aetiological factors (e.g. lead exposure, parental divorce, child abuse, family adversity, sexual orientation) to psychosocial adjustment; and (v) the psychosocial consequences of mental health problems in adolescence. Conclusions: The study findings illustrate the many advantages of a longitudinal study, such as the CHDS, in providing methodologically sound, theoretically relevant and cost effective research that caters for the interests of multiple end-users including the scientific community, clinicians and applied policy makers.

Objective: The aim of the present study was to provide a profile of young people attending alcohol and other drug (AOD) treatment services in Aotearoa, New Zealand. Method: Data were gathered from a clinical file search of 184 randomly selected young people aged 13-19 years who had attended one of eight youth AOD treatment services in New Zealand during 2003 or 2004. These services represented eight of the 11 youth-specific AOD services available to youth in New Zealand. Results: Young people who attend youth-specific AOD services in New Zealand present with a range of complex needs including substance use and mental health issues, criminality, family conflict and disengagement from school. A total of 62.0% were male, 56.4% had criminal convictions, 40.6% had spent some time in Child, Youth and Family Services care and 53.8% were reported to have a coexisting substance use and mental health disorder. Low rates of reporting of substance use and mental health diagnoses in treatment files suggest that substance use and mental health disorders among this population are likely to be higher than those reported. Conclusions: This paper provides a unique profile of young people attending youth-specific AOD treatments in New Zealand. Such information is useful in informing treatment planning and funding and ensuring that service development occurs to specifically meet the complex needs of this patient group.

Objective: The present accepted classificatory systems (ICD-10 and DSM-IV) represent the culmination of 100 years of post-Kraepelinian evolution. The present paper reports on a study to ascertain the views of New Zealand psychiatrists on their requirements of a classificatory system, and their opinions on those currently in use. Method: An anonymous postal survey of 542 psychiatrists and trainees was undertaken in New Zealand. Results: A total of 235 questionnaires were returned, completed. New Zealand psychiatrists primarily use DSM-IV and do so because that is what they were taught on. They make relatively limited use of the multiaxiality. The purposes of classificatory systems that they value most highly are reliable interclinician communication, and to inform patient management planning. The two purposes they valued least were usefulness for a national statistical base, or to indicate prognosis. Conclusions: New Zealand psychiatrists' views are consistent with some of the stated objectives of ICD-10 and DSM-IV, but there is significant diversity in the former and over-ambition in the latter, with much to be resolved.

Objective: This paper examines clinical and forensic outcomes for defendants found not guilty by reason of insanity in New Zealand, and explores the implications for policy development and clinical rehabilitation in this population. Method: All insanity acquittees disposed of by the courts as special patients after 1976 and released before 2004 are described. Their duration of inpatient care, rates of reconviction and rehospitalization following release are examined. The high resolution rate for violent crime reported to police suggests that reconviction rates are a reasonable proxy for violent reoffending. Factors predicting duration of inpatient care and reoffending are analysed. Results: Severity of Index Offence was the only variable predicting duration of inpatient care of the 135 special patients. Offenders of more serious offences were securely detained for longer periods – averaging 6 years in the case of those charged with murder. Most patients were readmitted over the decade following discharge. Only 6% had violently reoffended 2 years after release into the community. Prior offending, age at release, ethnicity and gender predicted reoffending, but not diagnosis or duration of inpatient admission. Conclusions: Following discharge into the community, insanity acquittees are reconvicted of violent crimes at a very low rate, although readmission to hospital is common. It may be that insanity acquittees are initially detained in hospital longer than is clinically indicated, and that safe forensic community treatment can occur at an earlier stage of recovery without compromising public safety.

Objective: To estimate the lifetime prevalence and projected lifetime risk at age 75 years of DSM-IV disorders in New Zealand. Method: A nationwide face-to-face household survey carried out in 2003–2004. A fully structured diagnostic interview, the World Health Organization Composite International Diagnostic Interview (CIDI 3.0), was used. There were 12 992 completed interviews from participants aged 16 years and over. The overall response rate was 73.3%. In this paper, the outcomes reported are lifetime prevalence and projected lifetime risk at age 75 years. Results: The lifetime prevalence of any disorder was 39.5%. The lifetime prevalences for disorder groups were: anxiety disorders, 24.9%; mood disorders, 20.2%; substance use disorders, 12.3%; and eating disorders, 1.7%. The prevalences for all disorders were higher in the younger age groups. Females had higher prevalences of anxiety, mood and eating disorders compared with males; males had higher prevalences of substance use disorders. The estimated projected lifetime risk of any disorder at age 75 years was 46.6% with the median age of onset being 18 years. Adjustment for age, sex, education and household income did not remove all differences between Māori and the composite other ethnic group in the risk of disorder (hazard ratio = 1.1–1.4). After adjustment, hazard ratios for Pacific people ranged from 0.8 to 2.5. Conclusions: These results confirm those of other studies: mental disorders are relatively common and tend to have early onset. Females are more likely to experience anxiety, mood and eating disorders than males, who experience more substance use disorders. Adjustment for socioeconomic factors and demography does not explain all ethnic differences, although remaining differences are small relative to cohort and even sex differences.

Objective: To estimate the 12 month and lifetime use of health services for mental health problems. Method: A nationwide face-to-face household survey carried out in 2003–2004. A fully structured diagnostic interview, the World Health Organization Composite International Diagnostic Interview (CIDI 3.0) was used. There were 12 992 completed interviews from participants aged 16 years and over. The overall response rate was 73.3%. In this paper, the outcomes reported are 12 month and lifetime health service use for mental health and substance use problems. Results: Of the population, 13.4% had a visit for a mental health reason in the 12 months before interview. Of all 12 month cases of mental disorder, 38.9% had a mental health visit to a health or non-health-care provider in the past 12 months. Of these 12 month cases, 16.4% had contact with a mental health specialist, 28.3% with a general medical provider, 4.8% within the human services sector and 6.9% with a complementary or alternative medicine practitioner. Most people with lifetime disorders eventually made contact if their disorder continued. However, the percentages seeking help at the age of onset were small for most disorders and several disorders had large percentages who never sought help. The median duration of delay until contact varies from 1 year for major depressive disorder to 38 years for specific phobias. Conclusions: A significant unmet need for treatment for people with mental disorder exists in the New Zealand community, as in other comparable countries. [ABSTRACT FROM AUTHOR]

Objective: To estimate the prevalence of chronic physical conditions, and the risk factors for those conditions, among those with 12 month mental disorder; to estimate the prevalence of 12 month mental disorder among those with chronic physical conditions. Method: A nationally representative face-to-face household survey was carried out in October 2003 to December 2004 with 12 992 participants aged 16 years and over, achieving a response rate of 73.3%. Mental disorders were measured with the World Mental Health version of the Composite International Diagnostic Interview (CIDI 3.0). Physical conditions were self-reported. All associations are reported adjusted for age and sex. Results: People with (any) mental disorder, relative to those without mental disorder, had higher prevalences of several chronic physical conditions (chronic pain, cardiovascular disease, high blood pressure and respiratory conditions) and chronic condition risk factors (smoking, overweight/obesity, hazardous alcohol use). Around a quarter of people with chronic physical conditions had a comorbid mental disorder compared with 15% of the population without chronic conditions. Significant relationships occurred between some mental disorders and obesity, cardiovascular disease and diabetes for females, but not for males. Conclusions: This paper provides evidence of substantial comorbidity between mental disorders and chronic physical conditions in New Zealand. This should be borne in mind by clinicians working in both mental health and medical services. [ABSTRACT FROM AUTHOR]

Objective: To estimate the 12 month prevalence of DSM-IV disorders in New Zealand, and associated interference with life and severity. Method: A nationally representative face-to-face household survey carried out in 2003–2004. A fully structured diagnostic interview, the World Health Organization World Mental Health Survey Initiative version of the Composite International Diagnostic Interview (CIDI 3.0) was used. There were 12 992 completed interviews from participants aged 16 years and over. The overall response rate was 73.3%. In this paper the outcomes reported are 12 month prevalence, interference with life and severity for individual disorders. Results: The prevalence of any disorder in the past 12 months was 20.7%. The prevalences for disorder groups were: anxiety disorders 14.8%, mood disorders 7.9%, substance use disorders 3.5%, eating disorders 0.5%. The highest prevalences for individual disorders were for specific phobia (7.3%), major depressive disorder (5.7%) and social phobia (5.1%). Interference with life was higher for mood disorders than for anxiety disorders. Drug dependence, bipolar disorder and dysthymia had the highest proportion of severe cases (over 50%), when severity was assessed over the disorder itself and all comorbid disorders. Overall, only 31.7% of cases were classified as mild with 45.6% moderate and 22.7% serious. Conclusions: Compared with other World Mental Health survey sites New Zealand has relatively high prevalences, although almost always a little lower than for the US. For all disorders, except specific phobia, interference with life was reported to be moderate, on average, which has lead to less than a third of cases being classified as mild. Most people who have ever met full DSM-IV criteria, including the impairment criterion, and who experience symptoms or an episode in the past 12 months find that their disorders impact on their lives to a non-trivial extent.

Objective: To describe the prevalence of mental disorders (period prevalence across aggregated disorders, 12 month and lifetime prevalence) among Māori in Te Rau Hinengaro: The New Zealand Mental Health Survey. Method: Te Rau Hinengaro: The New Zealand Mental Health Survey, undertaken between 2003 and 2004, was a nationally representative face-to-face household survey of 12 992 New Zealand adults aged 16 years and over, including 2595 Māori. Ethnicity was measured using the 2001 New Zealand census ethnicity question. A fully structured diagnostic interview, the World Health Organization World Mental Health Survey Initiative version of the Composite International Diagnostic Interview (CIDI 3.0), was used to measure disorder. The overall response rate was 73.3%. This paper presents selected findings for the level and pattern of mental disorder prevalence among Māori. Results: Māori lifetime prevalence of any disorder was 50.7%, 12 month prevalence 29.5% and 1 month prevalence 18.3%. The most common 12 month disorders were anxiety (19.4%), mood (11.4%) and substance (8.6%) disorders and the most common lifetime disorders were anxiety (31.3%), substance (26.5%) and mood (24.3%) disorders. Levels of lifetime comorbidity were high with 12 month prevalence showing 16.4% of Māori with one disorder, 7.6% with two disorders and 5.5% with three or more disorders. Twelve-month disorders were more common in Māori females than in males (33.6% vs 24.8%) and in younger age groups: 16–24 years, 33.2%; 25–44 years, 32.9%; 45–64 years, 23.7%; and 65 years and over, 7.9%. Disorder prevalence was greatest among Māori with the lowest equivalized household income and least education. However, differences by urbanicity and region were not significant. Of Māori with any 12 month disorder, 29.6% had serious, 42.6% had moderate and 27.8% had mild disorders. Conclusion: Mental disorders overall and specific disorder groups (anxiety, mood and substance) are common among Māori and measures of severity indicate that disorders have considerable health impact. Findings provide a platform for informing public health policy and health sector responses to meeting mental health needs of Māori. [ABSTRACT FROM AUTHOR]

To examine the likely utility of the recently published Australian and New Zealand clinical practice guidelines for the treatment of depression.The guidelines are critiqued for their intrinsic logic and their success in extracting potentially valid and useful management templates.This paper provides examples of key limitations to many specific interpretations and conclusions.It is argued that these guidelines are far less precise and informative for clinical practice than they appear and with a disturbing lack of rigour for a document promulgated by a professional college.

Background: The violent action of mentally ill people is a source of considerable public and professional concern. At times such incidents are subject to inquiry. In England and Wales, homicides by people suffering from mental illness are subject to mandatory external inquiry. Further, the Royal College of Psychiatrists coordinates a confidential research study into homicide and suicide by people in contact with mental health services. Inquiries have raised concern regarding widespread problems in mental health service delivery. Within New Zealand, similar concerns have been raised, but inquiries have been irregular and not of consistent methodology. The paper aims to review 10 years of inquiries into violent incidents to describe their methods, structure and findings. Method: All inquiries into violent actions perpetrated by patients in contact with mental health services between 1988 and 1998 and held by the Ministry of Health were reviewed. The nature of the inquiry, the incident, findings and recommendations were summarized. For each inquiry, an assessment was made as to whether the incident was predictable or preventable. Results: There were 11 incidents leading to 13 inquiries, six of homicide, two of rape, one of the release of a dangerous patient and two in which a patient was shot by police. Two internal inquiries were followed by external inquiries. All inquiries found deficiencies of varying severity, the degree of deficiency being greater with external inquiries. Consistent criticisms related to skill, resource, coordination and communication failures. Two of the 11 inquiries found the incident to be ‘predictable’, and eight to have been ‘preventable’. Conclusions: The problems in New Zealand are similar to those noted in England and Wales. Small numbers of inquiries make firm conclusions difficult, but the authors feel that a mandatory process of independent review of serious incidents is wise. [ABSTRACT FROM AUTHOR]

Objective: The paper describes the methodologies and results obtained on a large cohort of prison inmates in New Zealand who were screened for psychiatric disorder. Method: All women and remanded male inmates in New Zealand prisons, and a randomly selected cohort of 18% of sentenced male inmates were interviewed. Interviewers used the Composite International Diagnostic Interview – Automated to establish DSM-IV diagnoses, and the Personality Disorders Questionnaire to identify personality disorder. All prisons in New Zealand were visited. Results: The results indicate markedly elevated prevalence rates for major mental disorder in the prison population when compared with community samples. This is especially the case for substance misuse, psychotic disorders, major depression, bipolar disorder, obsessive– compulsive disorder and posttraumatic stress disorder. Of particular concern is not only the increased prevalence rates for schizophrenia and related disorders but also the high level of comorbidity with substance misuse disorders demonstrated by this group. While 80.8% of inmates diagnosed with bipolar disorder were receiving psychiatric treatment in the prison, only 46.4% of depressed inmates and 37% of those suffering from psychosis were receiving treatment. Maori inmates were grossly overrepresented in the remand, female and male sentenced inmate population compared with the general population. Conclusions: A significant increase in provision of mental health services is required to cope with the high number of mentally ill inmates. The level of need demonstrated by this study requires a level of service provision that is quite beyond the capacity of current forensic psychiatry services, Department of Corrections Psychological Services or the prison nursing and medical officers. The elevated rates of common mental disorders argues for the use of improved psychiatric screening instruments, improved assessment and treatment capacities in the prison and an increased number of forensic psychiatric inpatient facilities to care for those psychotic inmates who are too unwell to be treated in the prison.

Objective: This paper outlines the methods used, and preliminary descriptive data collected, in a study on a cohort of Maori and non-Maori patients admitted to the inpatient psychiatric services in Otago between 1990 and 1992. Method: The notes of 42 Maori and 217 non-Maori first admissions to psychiatric inpatients were reviewed. Information concerning this admission was entered onto a database and analysed. Results: The Maori admission rate was 4 per 1000 compared with 1 per 1000 for non-Maori people. This was higher than expected based on Otago population figures. Rates of family psychiatric history did not differ between Maori and non-Maori. Although Maori were found to have higher rates of social welfare support and were more likely to have no academic qualifications the differences were not significant. The sources of referral for Maori admissions were more likely to be from the law, and Maori were more likely to have had prior psychiatric inpatient treatment. The most common diagnosis for Maori and non-Maori was depressive disorders, and suicidal behaviour was common. Conclusions: Maori are overrepresented among first psychiatric inpatient admissions in Otago. They appear to be a more disadvantaged group with respect to financial support, academic qualifications and other health problems. The most common diagnosis did not differ between Maori and non-Maori cohorts. [ABSTRACT FROM AUTHOR]

Objective: The objective of this paper is to illustrate trends in Maori health, examine earlier health policies and to suggest avenues for improved mental health. Method: Several sources of historical and contemporary data have been reviewed and there has been some analysis of mental health policies as they relate to Maori. The interplay between culture, socioeconomic circumstances and personal health has been used as a context within which strategic directions are discussed. Results: Five strategies are highlighted: the promotion of a secure cultural identity, active Maori participation in society and the economy, improved mental health services, workforce development, autonomy and control. It is recommended that mental health services should be more closely aligned with primary health care, Maori youth, Maori-centred frameworks, and evidence-based practices. Conclusions: Improvements in Maori mental health require broad approaches which are consistent with Maori aspirations and coordinated across the range of sectoral and disciplinary interests. Active Maori participation in the process and the retention of a cultural base will be critical if the current trends are to be reversed. [ABSTRACT FROM AUTHOR]
