Chao-Cheng Lin of the National Taiwan University Hospital, Yu-Chuan Li of the National Yang-Ming University, and other colleagues in Taiwan developed the Internet-based Self-assessment Program for Depression (ISP-D). Between September 2001 and January 2002 the team recruited 579 subjects via a popular mental health website. Volunteers were sent a follow-up email one to two weeks after completing the first questionnaire inviting them to re-sit the test, and those who completed the questionnaires were offered a psychiatrist’s appointment to validate the diagnosis.
Results of the first assessment showed that 31% of participants had major depressive disorder, 7% a minor depressive disorder, 15% had some symptoms of depression that did not amount to a full diagnosis of depression (subsyndromal depressive symptoms) and 46% had no depression. Analysis of the retest results show excellent reproducibility for major depressive disorder. The reproducibility was lower for minor depressive disorder, which may be because minor depression is not a stable diagnosis. The psychiatrist’s follow-up revealed that the diagnosis was correct for ¾ of those tested online.
Already between 1/5 and 2/5 of the world’s population suffer from depression, but most remain undetected or go untreated, making it vital to provide more opportunities for diagnosis.
“The ISP-D provides a continuously available, inexpensive, and easily maintained depression screening method that is accessible to a large number of individuals across a broad geographic area,” write the authors. This tool allows people to reliably assess depression in themselves on their own and in a short amount of time.

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...
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...
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...
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...
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...
