RÉSUMÉ L’étude de l’acceptabilité renvoie à de nombreux modèles (Modèle d’acceptation des technologies : Davis, Bagozzi, & Warshaw, 1989 ; P3, Pouvoir, performance, perception : Dillon & Morris, 1999 ; ou encore Unified Theory of Acceptance and Use of Technology : Venkatesh, Morris, Davis, & Davis, 2003) pour prédire le comportement de l’utilisateur. Dans ces modèles le poids des variables sociales pour prédire l’intention d’usage ou le comportement de l’utilisateur est variable (de .02 à .51). Cet article a pour objectif d’analyser les déterminants de cette variabilité en convoquant deux dimensions permettant de mieux cerner l’intervention des variables sociales : la prise en compte des normes descriptives et injonctives (Cialdini, Reno, & Kallgren, 1990) d’une part et d’autre part la pesanteur sociale du comportement réalisé par l’utilisateur alors qu’il recourt à la technologie qu’on lui présente.
Children and adolescents account for half of all cases of type 1 diabetes, which is one of the most common pediatric chronic diseases. The disease's effects and the treatment/disease-management protocols patients must follow can lead to a marked deterioration in quality of life, especially for adolescents. Patients' illness perceptions have been shown to impact their quality of life, but do other people's illness perceptions also have an effect? The present study addressed this question by investigating possible links between the quality of life of adolescent patients with type 1 diabetes and illness perceptions, measured in terms of the adolescents' self-perceptions, parents' self-perceptions, and the adolescents' evaluations of their parents' perceptions. We asked 41 adolescents (M = 13.9 years; SD = 1.9) who had been undergoing treatment for type 1 diabetes for at least a year (M = 6.6 years; SD = 3.7) to complete the Diabetes Quality of Life for Youth Questionnaire-Short Form (DQOLY-SF) and the Illness Perception Questionnaire-Revised (IPQ-R). They completed the IPQ-R twice, once to state their own opinions (self-report) and once to give their evaluations of their parents' perceptions. At the same time, but in a different room, their parents (N = 47) completed the IPQ-R (self-report). Quality of life was predicted by gender (p < .05) and by the parents' emotional representations (p < .01) and perceptions of consequences (p < .01) as evaluated by the adolescents. This new approach provides new insights into the impact of parents' perceptions on the quality of life of adolescents with type 1 diabetes.
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.
