In early 2022, various kinds of text messages were sent to over 100,000 residents of Brabant-Zuidoost who had not yet received a booster jab from the GGD. The results show that the most effective variant − in the 6 days after receiving the text message − led to a 3.2% increase in the number of vaccinations administered. This was the text message saying 'Jouw boosterprik ligt voor je klaar' (You can now book your booster vaccination) plus a randomly allocated date, time and location. Why…

62% of times when an electronic device is broken their owner throw it away without thinking about repairing it, often encouraged by the industry. Consumers also think the information about "repairability" is hardly available at time of purchase. DITP created an indicator understandable and usable by consumers. Different types of labels were created to be tested in the field. Their clarity and impact on consumer's purchase decision were scientifically evaluated.

In Germany there are significant gaps in measles vaccination which lead to repeated outbreaks of the disease. Vaccinations do more than just protect the recipient against infection. They also protect people who cannot be vaccinated, for example infants or people with certain chronic illnesses. However, many adults do not know that they are not completely vaccinated against measles. In order to close this information and vaccination gap, wirksam regieren compared various possible ways to provide…

Hospital-care-associated infections (HCAIs) represent the most frequent adverse event during care delivery, affecting hundreds of millions of patients around the world. Implementing and ensuring conformity to standard precautions, particularly best hand hygiene practices, is regarded as one of the most important and cheapest strategies for preventing HCAIs. The behavioural sciences have documented the potential of adjusting seemingly irrelevant contextual features in order to ‘nudge’ people…

The project’s goal was to increase voter turnout among potential voters: registered voters who participated in one or fewer primary elections since 2000. Voting is a high-salience, socially important behavior that is essential to a functioning democratic society. While campaigns and organizations spend millions of dollars to increase voter turnout, recent research suggests that simple interventions like facilitating plan-making can help people follow through on their intentions.

30% of the requests CNAM (Primary health care institution in France) receives by phone or email could be made and treated online. In order to encourage use of online services, the CNAM solicited help from the DITP. This dematerialization would benefit the user by easing the access to services, to the administration workers by improving their work conditions and to the institutions through gains in efficience. We chose to target a precise procedure: ordering a Carte Vitale (Health Care card) for…

In Indonesia, as in other countries, a large proportion of tax returns are filed at the last minute. In a population-wide randomised controlled trial (n = 11,157,069), we evaluated the impact of behavioural email prompts on the proportion of annual tax returns filed at least two weeks before the deadline; and overall filing rate. In two control conditions, taxpayers either received no email or an email used in prior years, emphasising regulatory information. The five treatments informed by…

The study aims to identify barriers and trade-offs faced by consumers when deciding whether to engage in the circular economy. In particular, it explores decisions whether to buy a more or a less durable good, and whether to have a good repaired or to discard it and buy a replacement. It establishes the relative importance of economic, social and psychological factors that govern how consumers engage in the circular economy. Finally, it proposes policy tools to enable and encourage consumers to…

HPV…

The commercialization of formula milk (FM) began in Argentina at the end of the sixties. This market has grown remarkably since then, in turn, state agencies use LF as a tool to solve or combat low-weight problems in children and who for other reasons need to supplement the diet when milk is not possible exclusive breastfeeding (EBF). The increase in LF consumption is detrimental to breastfeeding (BF). Its introduction generates a vicious circle and dependency that is difficult to reverse…
