PURPOSE Prenatal screening should enable pregnant women to make informed choices. An informed decision is defined as being based on sufficient, relevant information and consistent with the decision maker's values. This study aims to assess to what extent pregnant women make informed choices about prenatal screening, and to assess the psychological effects(More)
OBJECTIVE The aim of the study is to study pregnant women's views on noninvasive prenatal testing (NIPT) for Down syndrome and the potential to test for a broader range of conditions. METHODS An online questionnaire available on the Dutch pregnancy fair website was completed by 381 pregnant women. RESULTS Of the women, 51% expressed interest in having(More)
OBJECTIVE Guidelines on primary prevention of cardiovascular disease (CVD) emphasize identifying high-risk patients for more intensive management, but patients' misconceptions of risk hamper implementation. Insight is needed into the type of patients that general practitioners (GPs) encounter in their cardiovascular prevention activities. How appropriate(More)
Perceived risk and representations of cardiovascular disease (CVD), and preventive behaviour of people diagnosed with Familial Hypercholesterolemia by DNA testing (N = 81) were assessed. In general, participants perceived their own CVD risk as being relatively low. While participants reported almost optimal medication adherence (99%), only 49 per cent(More)
BACKGROUND Patients are increasingly expected and asked to be involved in health care decisions. In this decision-making process, preferences for participation are important. In this systematic review we aim to provide an overview the literature related to the congruence between patients' preferences and their perceived participation in medical(More)
BACKGROUND New high-voltage power transmission lines will be introduced due to increasing demand for reliable and renewable energy supplies. Some residents associate non-specific health complaints with exposure to electromagnetic fields from nearby power lines. This study protocol describes the design and rationale of a prospective study investigating(More)
OBJECTIVE To assess the potential effectiveness of communicating familial risk of diabetes on illness perceptions and self-reported behavioral outcomes. RESEARCH DESIGN AND METHODS Individuals with a family history of diabetes were randomized to receive risk information based on familial and general risk factors (n = 59) or general risk factors alone (n =(More)
BACKGROUND Making evidence-based decisions often requires comparison of two or more options. Research-based evidence may exist which quantifies how likely the outcomes are for each option. Understanding these numeric estimates improves patients' risk perception and leads to better informed decision making. This paper summarises current "best practices" in(More)
BACKGROUND There is public concern about the potential health effects of exposure to extremely low frequency electromagnetic fields (ELF-EMF) of high-voltage power lines (HVPLs). Some residents living near HVPLs believe ELF-EMF might cause non-specific health complaints. OBJECTIVES The present study is the first to prospectively investigate whether(More)
Non-invasive prenatal testing (NIPT) and its potential to test for multiple disorders has received much attention. This study explores attitudes of women and men towards NIPT, and their views on widening the scope of prenatal testing in a country with a low uptake of prenatal screening (The Netherlands). Five focus groups with low-risk pregnant women(More)
