A national survey of health risk perception among 1,503 Canadians was conducted in 2004. The current survey follows-up a previous national survey conducted in 1992 and documents changes in risk perception since that time and investigates new risk issues not previously examined. This article presents a description of the ratings of perceived risk of thirty(More)
BACKGROUND Randomised controlled trials of implementation strategies tell us whether (or not) an intervention results in changes in professional behaviour but little about the causal mechanisms that produce any change. Theory-based process evaluations collect data on theoretical constructs alongside randomised trials to explore possible causal mechanisms(More)
Several trials have employed anxiety measures to assess decision aid effectiveness. This study employed a systematic review method to integrate their findings. The affective impact of decision aids and the appropriateness of anxiety as a measure of decision aid effectiveness are explored.

In the past it was assumed that work attendance equated to performance. It now appears that health-related loss of productivity can be traced equally to workers showing up at work as well as to workers choosing not to. Presenteeism in the workplace, showing up for work while sick, seems now more prevalent than absenteeism. These findings are forcing(More)
Differentials in health status and behaviour by socioeconomic status (SES) constitute a scientific and policy challenge. In this article, data from a national survey on Canadians' perceptions of population health risks were analysed to determine whether various types of health risk perceptions mediated SES differentials in health behaviour. As expected,(More)
OBJECTIVES The global impact of severe acute respiratory syndrome (SARS) brought attention to the role of healthcare professionals as "first receivers" during infectious disease outbreaks, a collateral aspect to their role as responders. This article records and reports concerns expressed by Canadian emergency and critical care nurses in terms of(More)
INTRODUCTION Three years following the global outbreak of severe acute respiratory syndrome (SARS), a national, Web-based survey of Canadian nurses was conducted to assess perceptions of preparedness for disasters and access to support mechanisms, particularly for nurses in emergency and critical care units. HYPOTHESES The following hypotheses were(More)
The volume of research on terrorism has increased since the events of September 11, 2001. However, efforts to develop a contextualized model incorporating cognitive, social-contextual, and affective factors as predictors of individual responses to this threat have been limited. Therefore, the aim of this study was to evaluate a series of hypotheses drawn(More)
BACKGROUND Theory-based process evaluations conducted alongside randomized controlled trials provide the opportunity to investigate hypothesized mechanisms of action of interventions, helping to build a cumulative knowledge base and to inform the interpretation of individual trial outcomes. Our objective was to identify the underlying causal mechanisms in a(More)
