First international index developed to predict suicidal behavior

10.03.2011
Although thousands of people commit suicide worldwide each year, researchers and doctors do not have any method for evaluating a person's likelihood of thinking about or trying to commit suicide. An international group of scientists, in which the Hospital del Mar Research Institute (IMIM) has participated, has devised the first risk index in order to prevent suicides.

"It is of key importance to identify suicidal thoughts among people at increased risk. The most important contribution that our study has made is an international risk index to estimate the likelihood of a person moving on from these thoughts to any one of the following behaviours – planning or trying to commit suicide", Jordi Alonso, head of the IMIM Healthcare Services Research Group, tells SINC.

The data used in the study, which also involved Josep M. Haro, a researcher at the Sant Joan de Déu Healthcare Park, and which has been published in the Journal of Clinical Psychiatry, come from the World Health Organisation (WHO) survey World Mental Health Surveys between 2001 and 2007, in which 108,705 adults from 21 countries responded to the Composite International Diagnostic Interview.

The study looks at suicidal behaviour rather than suicides that result in death, since it is based on interviews carried out with adults. The factors associated with such behaviour are – being female, younger age groups, lower levels of education, not living with a partner, being unemployed, suffering from certain mental illnesses, having experienced troubles during childhood, and mental illnesses among parents.

We are all at the same risk

Suicidal behaviour rates are similar in both developed and developing countries. In addition, "all the risk factors are similar for both these sets of countries, so the index used to determine the risk of suicidal behaviour is valid in both cases", the expert explains.

However, in terms of mortality as a result of suicide, there are significant variations around the world. For example, countries in eastern Europe and the former Soviet Union have the highest rates (Lithuania, Belarus, the Russian Federation), and a large number of those who die from suicide suffer from mental illnesses.

Other decisive factors involved in suicides being enacted include religion (meaning there are very low suicide rates in Muslim countries), social support and access to weapons or lethal substances.

Below the average but on the rise

In Spain, a country with a traditional Catholic culture with extended families, a relatively low prevalence of mental illnesses and significant restrictions on the use of weapons, suicide rates are low, at half the European average.

"However, this rate is on the rise, while in countries with higher rates it is falling", the researcher warns. In places such as the United States, for every death from suicide there are between three and four hospitalisations resulting from failed suicide attempts, and between 15 and 20 emergency room visits for the same reason.

"Our index for evaluating multiple risks could help to predict suicidal planning and attempts with a fairly high level of precision and help medical specialists to foresee such behaviour", concludes Alonso.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
