"No" doesn't always mean "no"

26.04.2007
Just because someone decides not to participate in a research project doesn't necessarily mean that they fundamentally object to taking part, a study published online in the open access journal BMC Health Services Research suggests.

Misunderstandings about the nature and process of a study often contribute to expressions of non-consent, a factor that should be incorporated in the design of future studies.

Low participation rates are a problem in human subject research because they can lead to delays, sampling bias and increased costs. Most studies to date have focussed on participants' motives for participation, so Brian Williams and colleagues from the University of Dundee, UK, decided to study the reasons why people chose not to take part in research projects.

They studied a group of older people living in Scotland who had opted out of a survey about retirement activities. Around half of the initial 887 people invited to participate declined to do so. Approximately 60% of these then agreed to take part in Williams' follow-up study and give reasons for their original refusal. Most were willing to take part, but had refused to do so because of confusion about the nature and purpose of the research, and perceived difficulties in participating because of other commitments. Only 28% indicated they were "not interested in research."

The results query the meaningfulness of expressions of 'non-consent' - a term that can encompass a variety of hidden personal decisions and motives. Reasons for non-participation are highly specific, not just to the research topic, but also to the potential participants. The information sheets that accompany participation requests should therefore aim to clarify any potential sources of confusion, and behavioural theory could be used to aid study design.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
