Research participation effects: a skeleton in the methodological cupboard☆

چکیده
OBJECTIVE There have been concerns about impacts of various aspects of taking part in research studies for a century. The concerns have not, however, been sufficiently well conceptualized to form traditions of study capable of defining and elaborating the nature of these problems. In this article we present a new way of thinking about a set of issues attracting long-standing attention. STUDY DESIGN AND SETTING We briefly review existing concepts and empirical work on well-known biases in surveys and cohort studies and propose that they are connected. RESULTS We offer the construct of "research participation effects" (RPE) as a vehicle for advancing multi-disciplinary understanding of biases. Empirical studies are needed to identify conditions in which RPE may be sufficiently large to warrant modifications of study design, analytic methods, or interpretation. We consider the value of adopting a more participant-centred view of the research process as a way of thinking about these issues, which may also have benefits in relation to research methodology more broadly. CONCLUSION Researchers may too readily overlook the extent to which research studies are unusual contexts, and that people may react in unexpected ways to what we invite them to do, introducing a range of biases.

متن کاملEffects of doorsill jet injection on fume cupboard containment.
The flow separation and its accompanied recirculation induced when the airflow passes over the inappropriately designed doorsill of a chemical fume cupboard are the key factors which would lead to deterioration of the cupboard performance. In order to alleviate the contaminant leakage of the fume cupboard induced by inherent aerodynamic deficiency, a technique using doorsill jet injection is de...

This study aims at empirically measuring a universal criterion for materials evaluation, i.e., learning opportunities, in a locally- and a globally-designed materials. Adopting the conceptual framework of sociocultural theory and its conceptualization of learning as participation (Donato, 2000), the researchers utilized the methodological power of conversation analysis to examine how opportunit...
