Le patient face à la technologie : étude des déterminants de l'acceptabilité des technologies en santé

Abstract : Introduction: In health psychology, few studies have been conducted to understand patients' perceptions of health technologies and need to be carried out. This work aims to identify and evaluate the determinants that make up the acceptability of new technologies in health, by associating developments from social psychology and health psychology.Methodology: To investigate patient and health professional acceptability of health technologies, we conducted three studies. We chose to use a multiple methods approach (Ajzen, 1991, Fisher & Tarquinio, 2006) in order to identify the different determinants predicting the intention to use technologies.Objectives and studies: The first objective of our work was to select the most suitable models of behavioral intention, and then tailor it by adding pertinent variables. The results, using the qualitative focus group methodology, revealed that the determinants proposed in the UTAUT model (Venkatesh, 2003) supplemented with affective and interpersonal determinants, seemed the most appropriate to evaluate the process of acceptability. In a second study, we proposed adapting the UTAUT model, associating an affective dimension composed of anxiety and trust in technology, and then testing the predictive power of this model with patients and health professionals. This model showed quite satisfactory results in predicting acceptability. In patients, the technologies are initially perceived through emotional and general components (perceived anxiety and attitude) whereas among experienced and familiar health professionals, the technologies are understood through cognitive and specific components (perceived utility and control). To optimize our model we added two new variable of the doctor-patient relationship representing the level of patient’s trust in the doctor and the effectiveness of the explanation of the technology (interpersonal dimension).Discussion: The proposal of an integrative model of acceptability of health technologies based on the UTAUT model, supplemented by an affective dimension and an interpersonal dimension, appears to be a promising model to understand users' perceptions of technologies.
