Uitkomstmaten
Primaire uitkomstmaten
1. Mean physical activity level will be measured by the self-administered short version of the International Physical Activity Questionnaire (IPAQ). Time points: Baseline, 3 months;<br>
2. Mean saturated fat intake using a validated short food frequency questionnaire, the short Fat list. Time points: Baseline, 3 months;<br>
3. Testing for diabetes: the percentage of people who test for diabetes after the risk information and attitudes towards taking a yearly or regular test for diabetes. Time points: Baseline, 3 months.
Achtergrond van het onderzoek
Family history is an important and independent risk factor for many common chronic diseases, reflecting the consequences of genetic predisposition, shared environment, and common behaviour. It is seen as a useful tool for disease prevention in public health and preventive medicine, and may be used for tailoring behavioural messages. Internet is seen as an effective way to improve health and disseminate information among the public, even when people do not perceive themselves at risk for disease. In this study type 2 diabetes is taken as an example. The main objective of this study is to investigate how the collection of a diabetes family history, interpretation and communication of familial risk information using a web-based tool affects health behaviour, and to explore the possible negative implications for individuals and their families.
Research questions are:
1. What is the impact of the collection of a family history of diabetes and communicating familial risk information of diabetes in a web-based tailored intervention on preventive behaviour?
A. What is the effect on health behaviour change (saturated fat intake, physical activity, test for diabetes)?
B. To what extent does the information affect causal beliefs, personal control, and perceived susceptibility?
C. Are people without a positive family history falsely reassured about their risk for diabetes, when the emphasis in the diabetes risk communication is on familial risk?
2. What are possible implications for the individual¡¯s freedom of choice, feelings of stigmatisation and discrimination, worries about confidentiality of the information, and impact on family relationships?

Onderzoeksproduct en/of interventie
The (web-based) intervention consists of:
