"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: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
