- Development and psychometric validation of a multidimensional scale on the self-care needs of dependent peoplePublication . Dixe, Maria dos Anjos; Soares, Elsa; Gomes, José Carlos; Pereira, Cidália; Carvalho, Daniel; Teixeira, Liliana; Sousa, Pedro Miguel Lopes; Amado, Sandra Cristina Fernandes; Peralta, Teresa de Jesus de Almeida; Lopes, Paulo; Querido, AnaObjectives: To develop and validate an interprofessional, multidimensional self-care needs scale of dependent people. Methodology: After a literature search, 61 items were identified and divided into nine self-care dimensions. The items were then reviewed by an expert panel (N = 11) to confirm the content validity of the scale. Refined items were pilot-tested in 12 patients, using a 5-point Likert-type scale. A final version was generated and psychometrically tested in 143 dependent men and women aged 37–102 (80.7 ± 10.1) years. Results: The nine multidimensional self-care needs scales were developed on a broad theoretical and empirical basis. The scales showed very good psychometric properties, having adequate characteristics, satisfactory reliability, and good validity. Conclusions: The scales have good psychometric properties, with minor differential item functioning. The scales can be used by health professional and policy makers to measure dependent people’s self-care needs. Nevertheless, it is necessary to perform further psychometric validations using a larger sample. This is an appropriate tool for application in clinical and research settings to assess patients’ self-care needs.
- Development of a distributed electronic system for low-cost heavy-duty engine test benchPublication . Rodrigues Gouveia, Olivier; Borges, Alexandre; Costa, Diogo; Coelho, Diogo; Lopes, Paulo; Perpétua, Hugo; Serrano, Luis; Ferreira, CarlosTest benches are important tools for the optimization and diagnosis of internal combustion engines. This paper presents the work done to develop a low-cost tech bench for heavy-duty engines, which uses an electromagnetic brake, to apply load to the engine, and a distributed electronic system for control and data acquisition. Signal noise contamination in test benches represents a problematic aspect of the engine testing. Moreover, a distributed control and monitoring electronic systems, allied with a Controller Area Network (CAN) communication bus for signal transmission, was used to mitigate and ultimately immunize signals from noise sources such as electric or electromagnetic fields. Overall, a heavy-duty test bench aiming the engines diagnostics was obtained, where all control and data acquisition is performed via an USB serial port, interfacing with two CAN bus networks, in a complete distributed control system.
- Psychometric Properties of the European Portuguese Version of the Memorial Emergency Department Fall Risk Assessment ToolPublication . Dixe, Maria dos Anjos Coelho Rodrigues; Querido, Ana; Mendonça, Susana; Sousa, Pedro; Monteiro, Helena; Carvalho, Daniel; Lopes, Paulo; Rodrigues, PedroFalls are a public health problem that cause serious damage to people’s health and health systems. This study aims to estimate the validity and reliability of the Memorial Emergency Department Fall Risk Assessment Tool for the European Portuguese population. The sample included 186 adults from an emergency department of a District Hospital in Portugal. Reliability and precision (inter-rater reliability) are assessed by two independent raters. The relationship between MEDFRAT and the Morse Fall Risk Scale is evaluated. All items presented a high Kappa index. The MEDFRAT showed a high and significant correlation with the Morse Fall Risk Scale. The influence of sociodemo graphic and clinical data was also checked. The MEDFRAT is adequate, valid and reliable for the European Portuguese population to assess the risk of falling of emergency department patients.
