Abstract(s)
Introdução: A demência afeta atualmente cerca de 55 milhões de pessoas em todo o mundo. Em fases mais avançadas, as Pessoas com Demência podem sentir dor sem conseguir verbalizá-la, dificultando a gestão da dor e acarretando sofrimento evitável. A aplicação móvel PainChek® é um dispositivo médico que permite a avaliação objetiva da dor quando o autorrelato está comprometido. Importa conhecer a usabilidade desta tecnologia digital antes da sua disponibilização em Portugal.
Objetivo: Avaliar a usabilidade da versão portuguesa (PT) da aplicação PainChek® por cuidadores formais de Pessoas que vivem com Demência.
Métodos: O estudo realizou-se em duas Estruturas Residenciais para Pessoas Idosas (ERPI), com base nas normas ISO 9241-11:2018 e ISO 25062:2025. Após formação presencial, a efetividade e eficiência foram avaliadas por observação de nove tarefas, com videogravação do ecrã e voz. Durante o desempenho das tarefas os participantes verbalizaram os seus pensamentos (Think-aloud). A satisfação foi avaliada por um questionário online que incluiu a versão portuguesa do Post-Study System Usability Questionnaire e perguntas abertas. Os dados textuais foram analisados tematicamente e procedeu-se à estatística descritiva dos dados quantitativos, com o apoio do Microsoft Excel.
Resultados: Obteve-se uma amostra de 19 participantes, sendo a maioria do sexo feminino (n=14;73.7%). A taxa média de sucesso na execução das tarefas foi de 91.3%. Contabilizou-se um total de 16 erros no conjunto das tarefas. O tempo médio para completar as tarefas variou entre 22 segundos (tarefa 9) e cerca de 6 minutos (tarefa 3). A tarefa 7 registou o maior número de tentativas (17). A média de satisfação dos participantes foi de 1.9, numa escala de 1 (mais positivo) a 7 (menos positivo).
Conclusão: A PainChek®-PT demonstrou efetividade, eficiência e satisfação neste contexto de utilização. Os problemas e defeitos de usabilidade identificados são um contributo para otimizar a sua usabilidade.
Introduction: Dementia currently affects around 55 million people worldwide. In more advanced stages, people with dementia may feel pain without being able to verbalise it, making pain management difficult and causing avoidable suffering. The PainChek® mobile application is a medical device that allows for the objective assessment of pain when self-reporting is compromised. It is important to understand the usability of this digital technology before it becomes available in Portugal. Aims: To evaluate the usability of the Portuguese (PT) version of the PainChek® application by formal carers of people living with dementia. Methods: The study was conducted in two Residential Structures for Elderly People (ERPI), based on ISO 9241-11:2018 and ISO 25062:2025 standards. After face-to-face training, effectiveness and efficiency were assessed by observing nine tasks, with screen and voice recording. During the performance of the tasks, participants verbalised their thoughts (Think-aloud). Satisfaction was assessed using an online questionnaire that included the Portuguese version of the Post-Study System Usability Questionnaire and open-ended questions. The textual data were analysed thematically and descriptive statistics were performed on the quantitative data, with the support of Microsoft Excel. Results: A sample of 19 participants was obtained, the majority of whom were female (n=14; 73.7%). The average success rate in performing the tasks was 91.3%. A total of 16 errors were counted across all tasks. The average time to complete the tasks ranged from 22 seconds (task 9) to about 6 minutes (task 3). Task 7 recorded the highest number of attempts (17). The average satisfaction of the participants was 1.9, on a scale from 1 (most positive) to 7 (least positive). Conclusions: PainChek®-PT demonstrated effectiveness, efficiency and satisfaction in this context of use. The usability problems and defects identified contribute to optimising its usability.
