Résumé
Introduction : L’utilisation des dispositifs numériques en sante améliorerait certains résultats cliniques. Proposer des interventions ≪ en ligne ≫ efficaces visant l’amélioration du processus d’adaptation des patients vivant avec une maladie chronique nécessite de disposer d’une mesure validée de la littératie en sante numérique. La mesure autorapportée ≪ Lisane ≫ a été construite et validée par des experts. Objectifs : Décrire le test sur le terrain de la version préliminaire de l’outil, plus spécifiquement le taux de non-réponse, les effets plafond et plancher, la redondance d’items et l’évaluation préliminaire de sa cohérence interne. Méthode : L’outil Lisane, compose de 14 items divises en 5 domaines (e-littératie, fiabilité de l’information sur Internet, pertinence de l’information pour la sante personnelle, protection de la vie privee, pouvoir d’agir), a été applique auprès d’un échantillon de convenance (29 participants) recrute au Québec (communautés de patients) et en Suisse (milieu clinique). Le taux de non-réponse, les effets plafond et plancher ont été évalués. La redondance d’items a été décrite a titre exploratoire. La cohérence interne a été évaluée par le coefficient alpha de Cronbach. Résultats : Le taux de résultats manquants > 15% et une redondance (r = 0,94, p<0,05) des items du pouvoir d’agir ont été relevés. Un effet plancher a été identifie. L’alpha de Cronbach était de : α= 0,90, IC 95% [0.78 – 1.03]. Discussion et conclusion : Le test sur le terrain indique des limites dans l’outil, comme un effet plancher et l’indication de redondance de certains items, mais une bonne évidence préliminaire de cohérence interne. La continuité d’analyse de ses propriétés psychométriques (validité, fidélité) s’avère nécessaire.
Introduction: The use of digital health devices (e-health) would improve certain patient’s clinical outcomes. Proposing effective “online” interventions to improve patients’ adaptation to chronic conditions requires a validated measure of digital health literacy. The “Lisane” self-report measure was developed and validated by experts. Objectives: This article describes the field-testing of the preliminary version of the tool, more specifically the non-response rate, ceiling and floor effects, item redundancy and the preliminary assessment of its internal consistency. Method: The Lisane tool, consisting of 14 items divided into five domains (e-literacy, reliability of information on the Internet, relevance of information to personal health, protection of privacy, empowerment), was applied to a convenience sample (29 participants) recruited in Quebec (patient communities) and Switzerland (clinical setting). The non-response rate and the ceiling and floor effects were evaluated. Item redundancy was described for exploratory purposes. Internal consistency was assessed using Cronbach's alpha coefficient. Results: The rate of missing results > 15% and a redundancy (r = 0.94, p<0.05) on power to act’s items were noted. A floor effect was identified. Cronbach’s alpha was α= 0.90, 95% CI [0.78 – 1.03]. Discussion and Conclusion: The field test of the Lisane tool has limitations, such as a ceiling effect and the indication of redundancy in certain items, but good preliminary evidence of internal consistency. Continued analysis of its psychometric properties (validity, reliability) is necessary.
