Entre 18 et 25 ans, les jeunes adultes doivent prendre pour la première fois la décision de se faire vacciner (rappel du vaccin DTP). Adoptant une démarche expérimentale, cette étude menée auprès de 303 jeunes adultes teste l’efficacité de 6 combinaisons de messages pro-vaccination DTP sur les changements d’attitude et d’intentions comportementales, en faisant varier le cadrage (gain vs. perte) et l’argument utilisé (se faire vacciner pour soi, pour les autres, ou pour respecter la loi). Les résultats montrent que selon l’option, la communication est soit peu performante, soit contreproductive, en diminuant l’intention de vaccination. Il ressort également que certains cadrages sont à l’origine d’une chaîne séquentielle de nature soit plutôt affective, soit plutôt cognitive. Finalement, l’option la plus efficace consiste à développer des messages à partir du cadrage gain / légal : « Se faire vacciner, c’est respecter la loi ».
Information and communication technologies (ICTs) are omnipresent and define the interactions in society. Within society, there are vulnerable groups of people for whom ICT use is more challenging. Disabled people are the most vulnerable ICT users. To identify the digital divides of access and impact of ICT on disabled users, an exploratory qualitative study was conducted. Relying on a French national association for disability that grants unique access to disabled ICT users, two focus groups and 10 in-depth interviews were carried. The study allows to propose a model of ICT use and effects for disabled people, integrating several types of disabilities. The results show that ICT appropriation by disabled users depends on their perceived self-efficacy in ICT. ICT use can lead to negative effects, including social exclusion and low perceived normalcy. To address societal interests and develop the literature, a research agenda is proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
