Abstract(s)
Os sítios Web são a face das instituições, mas há evidências de frequentemente serem
pouco cuidados, sobretudo ao nível dos seus conteúdos. Nesta tese apresentamos uma
investigação que desenvolve um modelo de avaliação da qualidade dos conteúdos de
sítios Web de unidades de saúde. A revisão bibliográfica, realizada neste trabalho,
permitiu identificar as dimensões e atributos de avaliação da qualidade de conteúdos de
sítios Web mais considerados pelos diversos autores dos trabalhos mais importantes da
área, mas não um modelo que, a partir deles, fosse capaz de os avaliar objetivamente.
Assim, levantou-se o problema de saber se todos os atributos têm a mesma importância.
Atributos mais importantes devem dar maior contributo na avaliação pretendida e o
modelo a ser considerado deve refletir isso, adicionalmente a ferramenta de avaliação
deveria ser intuitiva e rápida na aplicação. Para determinar a importância de cada
atributo aplicou-se o Método Delphi tendo sido necessário três rondas para encontrar
consenso relativamente à importância dos atributos a que se seguiu a aplicação de um
conjunto de modelos estatísticos de forma a determinar uma métrica consistente e que
permitisse a comparação de pontuações entre sítios web. De acordo com as questões de
investigação e os objetivos definidos foi possível encontrar um modelo que fornecesse
uma medida objetiva, normalizada e consistente acerca da qualidade de conteúdos de
sítios web de unidades de saúde.
Websites are institutional entry points, but there is evidence that they are often not cared enough, particularly when we look at their contents. In this thesis we present a research, leading to a model for assessing the quality of website contents, when applied to healthcare institutions. The literature review conducted in this work, allowed us to identify the attributes and dimensions of quality assessment, when applied to Website content. These attributes have been considered by the main authors in the area, but no formal model was derived from them, which would be able to objectively assess quality as a whole. It is important to determine if all attributes have the same importance. Most important attributes should give greater contribution in the required review, and the model to be considered should reflect this. Additionally, our assessment tool should be intuitive and applied quickly. To determine the importance of each attribute, we used the Delphi method; three rounds were needed to find a consensus on the importance of attributes. This was followed by the application of a set of statistical models to determine a consistent metric, which enables the comparison of scores between websites. According to the research questions and objectives set, we were able to find a model that provides an objective, standardized and consistent view on the quality of content in websites of healthcare facilities.
Les sites Web sont la vitrine des institutions, cepandant il est prouvé qu'ils sont souvent peu soignés, notamment en termes de leur contenu. Dans cette thèse, nous présentons le développement d'un modèle de recherche pour l'évaluation de la qualité du contenu de sites Web d'établissements de santé. La revue de littérature réalisée dans ce travail identifie les dimensions et les caractéristiques de l'évaluation de la qualité du contenu de sites Web considérés par de nombreux auteurs. Toutefois aucune étude presente un modèle permettant d'évaluer objectivement la qualité de sites Web. Pour obtenir um tel modèle, il est necessaire savoir si tous les attributs ont la même importance. D'autre part, les attributs importants doivent avoir une plus grande contribution dans le processus d'evaluation. L'outil d'évaluation doit être, egalement, intuitif et rapide à appliquer. Afin de déterminer l'importance de chaque attribut, la méthode Delphi a été appliqué. L'application de modèles statistiques a egalement été appliqué pour déterminer une métrique uniforme et permettre la comparaison des résultats entre sites Web. En accord avec les questions d'investigation et les objectifs definis, un modèle a été elaboré permettant fournir une mesure objective, normalisée et cohérente de la qualité du contenu de sites Web d'établissements de santé.
