Objective: The 2010 Survey of High Impact Psychosis (SHIP) is Australia’s second national psychosis survey. This paper provides an overview of its findings, including comparisons with the first psychosis survey and general population data. Methods: The survey covered 1.5 million people aged 18–64 years, approximately 10% of Australians in this age group. A two-phase design was used. In phase 1, screening for psychosis took place in public mental health services and non-government organizations supporting people with mental illness. In phase 2, 1825 of those screen-positive for psychosis were randomly selected and interviewed. Data collected included symptomatology, substance use, functioning, service utilization, medication use, education, employment, housing, and physical health including fasting blood samples. Results: The estimated 1-month treated prevalence of psychotic disorders in public treatment services was 3.1 people per 1000 population; the 12-month treated prevalence was 4.5 people per 1000. The majority (63.0%) of participants met ICD-10 criteria for schizophrenia/schizoaffective disorder. One-half (49.5%) reported attempting suicide in their lifetime and two-thirds (63.2%) were rated as impaired in their ability to socialize. Over half (54.8%) had metabolic syndrome. The proportion currently smoking was 66.1%. Educational achievement was low. Only 21.5% were currently employed. Key changes in the 12 years since the first survey included: a marked drop in psychiatric inpatient admissions; a large increase in the proportion attending community mental health clinics; increased use of rehabilitation services and non-government organizations supporting people with mental illness; a major shift from typical to atypical antipsychotics; and large increases in the proportions with lifetime alcohol or drug abuse/dependence. Conclusion: People with psychotic illness face multiple challenges. An integrated approach to service provision is needed to ensure that their living requirements and needs for social participation are met, in addition to their very considerable mental and physical health needs.

Worldwide, there is an increase in ecosystem distress syndromes matched by a corresponding increase in human distress syndromes. The specific role played by global-scale environmental challenges to 'sense of place' and identity will be explored in the future development of the concept of solastalgia.

The DIP is suitable for use in large-scale epidemiological studies of psychotic disorders, as well as in smaller studies where time is at a premium. While the diagnostic module stands on its own, the full DIP schedule, covering demography, social functioning and service utilization makes it a versatile multi-purpose tool.

BackgroundThere are insufficient data from nationwide surveys on the prevalence of specific psychotic disorders and associated co-morbidities.MethodThe 2010 Australian national psychosis survey used a two-phase design to draw a representative sample of adults aged 18–64 years with psychotic disorders in contact with public treatment services from an estimated resident population of 1 464 923 adults. This paper is based on data from 1642 participants with an International Classification of Diseases (ICD)-10 psychotic disorder. Its aim is to present estimates of treated prevalence and lifetime morbid risk of psychosis, and to describe the cognitive, physical health and substance use profiles of participants.ResultsThe 1-month treated prevalence of psychotic disorders was 3.10 cases per 1000 population aged 18–64 years, not accounting for people solely accessing primary care services; lifetime morbid risk was 3.45 per 1000. Mean premorbid intelligence quotient was approximately 0.5 s.d.s below the population mean; current cognitive ability (measured with a digit symbol coding task) was 1.6 s.d.s below the population mean. For both cognitive tests, higher scores were significantly associated with better independent functioning. The prevalence of the metabolic syndrome was high, affecting 60.8% of participants, and pervasive across diagnostic groups. Of the participants, two-thirds (65.9%) were current smokers, 47.4% were obese and 32.4% were sedentary. Of the participants, half (49.8%) had a lifetime history of alcohol abuse/dependence and 50.8% lifetime cannabis abuse/dependence.ConclusionsOur findings highlight the need for comprehensive, integrative models of recovery to maximize the potential for good health and quality of life for people with psychotic illness.

People with psychotic illness included in the survey sample. 7,955 people were identified through the three cohort entry pathways. Of these, a sample of 1,825 was randomly selected for interview. People with psychotic illness not included in the survey sample.

Existing rurality categories cannot address the diverse socio-cultural, economic and environmental characteristics of non-metropolitan regions. While it has limitations, the dataset will enable a fine-grained examination of geographic, household and community factors and provide a unique longitudinal dataset over a five-year period.
