The Centre of Research Excellence in Suicide Prevention (CRESP) brings together leading Australian and international experts to undertake research and drive rapid advances in suicide prevention.
Suicide Prevention RCT Database
The Suicide Prevention RCT Database project is a database of randomised controlled trials of psychosocial interventions targeting suicidal behaviour. The database has been compiled through a series of comprehensive literature searches and categorises included studies according to a number of key characteristics. The database is updated yearly by researchers funded through the Australian National Health and Medical Research Council Centre for Research Excellence for Suicide Prevention (CRESP).
It is available for use by researchers in the suicide prevention field by accessing the menu items on the left. By providing researchers with access to such an up-to-date resource, the database aims to stimulate an increase in the efficiency, relevance and quality of reviews in the area of suicide prevention, allow independent reanalysis of prior findings and provide a strong starting point for systematic reviews and meta-analyses of treatments and interventions. Importantly, this database provides a comprehensive overview of the existing knowledge in the suicide prevention field, and adds to the evidence base of best-practice psychosocial interventions for suicidal behaviour and prevention.
The database has been designed and collated by a group of researchers from the Black Dog Institute in Sydney Australia (University of New South Wales), and the Centre for Mental Health Research, Australian National University in Canberra Australia, under the auspices of the National Health and Medical Research Council (NHMRC) Centre of Research Excellence in Suicide Prevention (CRESP), located at the Black Dog Institute. The principal researcher is Professor Helen Christensen, Director of the Black Dog Institute and Chief Investigator of CRESP. Ongoing maintenance and refinement of the database will be undertaken by the research team, and managed by Professor Christensen.
This website allows suicide prevention researchers to access the database and its included studies to facilitate replications and independent re-analysis of selections of studies. It provides a strong starting point for systematic reviews and meta-analyses of treatments and interventions. The database provides a comprehensive overview of up-to-date knowledge in suicide prevention, and adds to the evidence base of best-practice interventions in this growing field.
We have conducted a series of comprehensive systematic literature searches to identify randomized controlled trials. The methodology used to compile the database is described in the Open Access paper below: Christensen H, Calear AC, Van Spijker B, Gosling J, Petrie K, Donker T, Fenton K. Psychosocial interventions for suicidal ideation and attempts: A database of randomised controlled trials. BMC Psychiatry 2014, 14:86 doi:10.1186/1471-244X-14-86. http://www.biomedcentral.com/1471-244X/14/86
We have made available some of the files that can be used for analysis of the database, which can be downloaded from this website. We also provide a listing of publications by our research team based on included studies in our database. Although we have conducted regular comprehensive literature searches in this field, relevant papers may have been missed. Please contact us if you are aware of a study that may be eligible for inclusion in our database.
Additionally, this database does not provide effect sizes or quantitative measures of differences between control and intervention groups. Because different statistical approaches are indicated, these indicators will need to be drawn directly from the research papers by the interested research groups. Similarly, coded variables included may not be those of interest to particular researchers, who may need to code new variables or recode existing variables.
To date, we present only data on psychosocial randomised controlled trials for suicidal behaviour. Nevertheless, variables included in this database will be reviewed upon each update, with variables such as study quality and inclusion/calculation of effect sizes to be introduced at later iterations. We are continuously working on the update of the available information at this website.
The current database has the potential to stimulate an increase in the efficiency, relevance and quality of reviews in the area of suicide prevention, as well as informing future research directions.

To date, 154 studies are included in our database. These 154 trials were identified through comprehensive literature searches of bibliographic databases for articles published between 1800 to December 30, 2014. This dataset contains only studies which featured a randomised controlled design in which the effects of a psychosocial intervention were compared to a control condition (no intervention, attention placebo, wait-list, treatment-as-usual [TAU]), another psychosocial intervention or a pharmacological intervention.
Each included study has been coded into categories describing:
- participant characteristics (age, gender, formal diagnosis, primary reason for recruitment);
- details of the intervention (recruitment setting, content, intervention setting, administering individual, delivery type, delivery format, delivery frequency, delivery length);
- study characteristics (control and experimental conditions, primary outcome/s, secondary outcome/s, follow-up period).

Canberra Longitudinal Study
The Canberra Longitudinal Study is a 12-year study investigating health and memory in older people. The longitudinal study began in 1990 (with subsequent waves in 1994, 1998 and 2002). The 2002 wave was the last time that participants were approached for interviews, when the youngest participant was 82 years old.

Personality and Total Health (PATH) Through Life
The PATH Through Life project is a 20-year longitudinal cohort study of 7,485 young, midlife and older adults. Participants were randomly sampled from the electoral roll of the Australian Capital Territory and the nearby city of Queanbeyan.
The project aims to:
- track and define how depression, anxiety, substance use and cognitive ability develop in individuals
- identify environmental risk and protective factors within these domains
- examine the relationships between depression, anxiety and substance use with cognitive ability and dementia
Dunedin Multidisciplinary Study
The Dunedin Multidisciplinary Health and Development Study is a longitudinal cohort study that began in 1972. Participants in the study were all born between 1 April 1972 and 31 March 1973 at the Queen Mary Maternity Hospital in Dunedin, New Zealand. Of the original 1037 babies, 1014 participants are still alive today.
The babies were first followed up when they were 3-year-old, and then at 5, 7, 9, 11, 13, 15, 18, 21, 26, 32 and 38. Further assessments are scheduled for the future.
During each follow up almost all aspects of participants’ physical and mental health are examined, including:
- cardiovascular heal
- dental heal
- respiratory heal
- sexual heal
- mental heal
- psychosocial wellbeing
Detailed interviews about the participants’ relationships, behaviour and family are also conducted.
Sub-studies of the Dunedin Study, include:
- the Family health history Study (2003-2006) which involved the parents of the study members
- the Parenting Study (involving study members who are parenting 3-year-old pre-schoolers)
- the Next Generation Study (involving study members who are parenting 15-year-old teenagers).
Christchurch Longitudinal Study
The Christchurch Health and Development Study (CHDS) follows the health, education and life progress of a group of 1,265 children born in the Christchurch, New Zealand during mid-1977. This cohort has now been studied from infancy into childhood, adolescence and adulthood. Some key research themes include: the mental health effects of cannabis use and alcohol use in young people, mental health and treatment seeking, and suicidal behaviour in young adults (in collaboration with the Canterbury Suicide Project).
The study has published over 400 scientific papers, reports, books and book chapters describing the 30-year life history of the CHDS cohort.
Brisbane Longitudinal Twin Study
The Queensland Institute of Medical Research’s (QIMR) Brisbane Longitudinal Twin Study (BLTS) began in 1992. Twins were recruited from schools in the greater Brisbane area. The sample includes both monozygotic and dizygotic twin pairs (including opposite-sex dizygotic twin pairs) singleton siblings of twins, and the twins’ parents. There are a total of 1,703 families involved with the study.
Approximately 100 new twins are recruited each year to the study. The BLTS data focuses on psychiatric conditions such as anxiety, depression, schizophrenia, bipolar disorder, alcoholism and drug abuse, as well as common diseases such as melanoma, asthma, endometriosis (a condition that affects a woman’s reproductive system) and migraines.
The data from the study is a longitudinal collection of psychiatric phenotypes, environmental and psychological risk factors, as well as neurobiological correlates and endophenotypes for psychiatric disorders.

Developed at the Black Dog Institute, the Black Dog Index assesses the mental health of Australians, looking at the level of happiness as well as depression, anxiety and suicidal thoughts. The index was developed because economic-based measures do not sufficiently reflect a country's health, with the UK and Canada also having similar measures. It is conducted by Newspoll every three months with results reported in 'The Australian'.
The ECCO Project
The Exploring Continued Care Options (ECCO) trial is a collaboration between the Australian National University’s e-hub and Lifeline Australia. The trial examined the effectiveness of an online depression intervention for callers to a national telephone counselling service (Lifeline). Using a randomised controlled trial, the results found that online depression interventions (i.e. MoodGYM and BluePages websites) were effective in reducing depression in Lifeline callers. The online intervention was found to be effective with and without ongoing telephone tracking.
The ECCO project won a Silver Award at the 2010 Mental Health Services Achievement Awards, in the category of e-health.
The aim of the Climate and Preventure (CAP) study is to trial two school-based prevention programs to prevent substance use and related harms. The universal ‘Climate Schools’ program, and the selective personality-targeted ‘Preventure’ program would ideally delay the onset of substance use in both:
- adolescents with low-risk profiles who may be influenced to take up substances due to peer influence and social conformity
- adolescents with high-risk profiles whose underlying vulnerability to psychopathology may lead to substance misuse.
The CAP intervention builds on the National Drug and Alcohol Research Centre unique success in this area through developing effective online school-based programs.

45 and Up Study
The 45 and Up Study is the largest study of healthy ageing ever undertaken in the Southern Hemisphere. The longitudinal study will follow around 250,000 over 45-year-old people from across NSW, (which is about 10% of this age group). Over the coming decades the cohort and their health will be followed.
Growing Up in Australia: The Longitudinal Study of Australian Children
Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC) is following the development of 10,000 children and families from all parts of Australia. The study commenced in 2004 with two cohorts (families with 4-5 year old children and families with 0-1 year old infants). The researchers are interested in investigating the contribution of a child’s social, economic and cultural environments to their adjustment and wellbeing. The main aim of the study is to identify policy opportunities, early interventions and prevention strategies that could improve support for children and their families.
Bettering the Evaluation and Care of Health (BEACH)
The BEACH program is a cross-sectional, paper-based data collection system developed and validated by the University of Sydney. The program continuously collects information about the clinical activities in general practice in Australia. The BEACH database currently includes about 1,780,000 GP-patient encounter records (04/2016). The data collected is used by researchers, and government, industry and non-government organisations. Detailed information is available on the BEACH website.
Australian Longitudinal Study on Women’s Health
The Australian Longitudinal Study on Women’s Health (ALSWH) is a population-based survey examining the health of over 58,000 Australian women. The study is the most comprehensive ever conducted on the health of Australian women. The study assesses physical and mental health, psychosocial aspects of health (such as socio-demographic and lifestyle factors) and use of health services. ALSWH is funded by the Australian Department of Health and Ageing. Extensive details about the project can be found online.
