This ‘cohort profile’ aims to provide a description of the study design, methodology, and baseline characteristics of the participants in the Corona Behavioral Unit cohort. This cohort was established in response to the COVID-19 pandemic by the Dutch National Institute for Public Health and the Environment (RIVM) and the regional public health services. The aim was to investigate adherence of and support for COVID-19 prevention measures, psychosocial determinants of COVID-19 behaviors, well-being, COVID-19 vaccination, and media use. The cohort also examined specific motivations and beliefs, such as for vaccination, which were collected through either closed-ended items or open text responses. In April 2020, 89,943 participants aged 16 years and older were recruited from existing nation-wide panels. Between May 2020 and September 2022, 99,676 additional participants were recruited through online social media platforms and mailing lists of higher education organizations. Participants who consented were initially invited every three weeks (5 rounds), then every six weeks (13 rounds), and since the summer of 2022 every 12 weeks (3 rounds). To date, 66% of participants were female, 30% were 39 years and younger, and 54% completed two or more questionnaires, with an average of 9.2 (SD = 5.7) questionnaires. The Corona Behavioral Unit COVID-19 cohort has published detailed insights into longitudinal patterns of COVID-19 related behaviors, support of COVID-19 preventive measures, as well as peoples’ mental wellbeing in relation to the stringency of these measures. The results have informed COVID-19 policy making and pandemic communication in the Netherlands throughout the COVID-19 pandemic. The cohort data will continuously be used to examine COVID-19 related outcomes for scientific analyses, as well as to inform future pandemic preparedness plans.

The studies in this thesis aim to increase understanding of the effects of various characteristics of scientific news about a common chronic disease, i.e., diabetes, on the cognitive responses (e.g., emotions, attitudes, intentions) of diabetes patients. The research questions presented in this thesis are guided by the Health Belief Model, a theoretical framework developed to explain and predict healthrelated behaviours based on an individual’s beliefs and attitudes. The model asserts that perceived barriers to a recommended health behavior, advantages of the behavior, self-efficacy in executing the behavior, and disease severity and personal susceptibility to the disease are important predictors of a health behavior. Communication is one of the cues to action (i.e., stimuli) that may trigger the decision-making process relating to accepting a medical or lifestyle recommendation.
De uitingen van de crossmedia dringen zich steeds nadrukkelijker aan ons op. Een toenemend aantal crossmedia diensten en producten doet een beroep op onze aandacht en financiën: van interactieve televisieprogrammas op websites, tot themakanalen op mobiele apparaten, fysieke bijeenkomsten van online communities, en virtuele werelden waarin wordt gehandeld, gestolen en waarin je echte schulden kan maken. Oude en nieuwe media vinden elkaar in IPTV en podcasts. Traditionele spelers worden links en rechts ingehaald door creatieve pioniers en actieve consumenten die zich niets aantrekken van bestaande marktverdelingen en gevestigde namen. De ene baanbrekende dienst valt over de andere innovatie heen: nog maar net gewend aan het bloggen of iedereen slaat aan het twitteren. Zelfs een achteloze journaalkijker kan de hysterische taferelen die hiermee soms gepaard gaan niet ontlopen, blijkens de nieuwe introductie van een oud apparaat zoals de telefoon: de iPhone.
