- Development and validation of a Portuguese psychologist's empathy scale: a pilot studyPublication . Cruz, Márcia; Grilo, Ana; Custódio, Susana; Dores, Artemisa R.; Silva, Carina; Alves, PauloThe systematic assessment of empathy is essential for identifying psychologists' competencies and developmental needs, ultimately contributing to more effective clinical practice. Given the multidimensional nature of empathy, comprehensive evaluation requires consideration of its cognitive, affective, and behavioural dimensions. However, no existing instrument is specifically validated to assess psychologists' self-perceived empathy in clinical contexts. To address this limitation, the present pilot study aimed to develop and undertake a preliminarily validation of the Portuguese Psychologists' Empathy Scale (PPES), a self-report instrument designed to assess empathy among psychologists working in Portuguese-speaking contexts across these three components. The study proceeded in two phases: item construction and initial psychometric testing. A total of 106 Portuguese psychologists completed a 57-item Likert-type instrument. Bartlett's test of sphericity was significant (χ2(45) = 811.56, p < .001), and the KMO index (0.73) indicated moderate adequacy for factor analysis. Exploratory factor analysis revealed three core factors explaining 48% of the total variance, with strong internal consistency. A subsequent confirmatory factor analysis supported model refinement, leading to the removal of items with low factor loadings. The final PPES comprises 43 items distributed across cognitive (16), affective (16), and behavioural (11) dimensions. The findings provide encouraging preliminary evidence for the PPES, demonstrating robust internal consistency and acceptable initial factorial validity. Nevertheless, further studies using independent samples and external validation procedures are required to fully establish its psychometric soundness and clinical applicability with Portuguese-speaking psychologists.
- A malnutrição associada à doença e as suas repercussões em PortugalPublication . Marinho, Anibal; Lopes, Ana; Sousa, Gabriela; Antunes, Henedina; Fonseca, Jorge; Mendes, Lino; Carvalho, Mamede de; Veríssimo, Manuel Teixeira; Carvalho, Nuno; Alves, Paula; Alves, PauloA malnutrição associada à doença é frequente do ponto de vista clínico, apresentando elevada morbilidade, mortalidade e impacto na qualidade de vida, em especialidades como a medicina interna, a oncologia, a neurologia, a gastroenterologia e a pediatria, entre outras. Estudos realizados em Portugal estimam existirem cerca de 40% de doentes em risco nutricional à data da admissão hospitalar, dependendo do estadio da doença e do grau/severidade. O custo da hospitalização destes doentes, é cerca de 20% superior ao dos doentes com o mesmo grupo de diagnóstico homogéneo, mas sem risco nutricional associado. No nosso país, o acesso dos doentes malnutridos a avaliação, aconselhamento e tratamento nutricional adequados ainda é limitado, mesmo em ambiente hospitalar. Um conhecimento detalhado da malnutrição associada à doença nas referidas especialidades, permitiria uma melhor caracterização da situação em Portugal, e permitiria estabelecer uma estratégia de intervenção clínica e terapêutica, para melhorar este panorama e as suas consequências no nosso país.
- The Portuguese national seismic network: products and servicesPublication . Carrilho, Fernando; Custodio, Susana; Bezzeghoud, Mourad; Oliveira, Carlos; Marreiros, Célia; Vales, Dina; Alves, Paulo; Pena, Areosa; Madureira, Guilherme; Escuer, Maria; Silveira, Graça; Corela, Carlos; Matias, Luis; Silva, Matilde; Veludo, Idalina; Dias, Nuno; Loureiro, Afonso; Borges, J. F.; Caldeira, Bento; Wachilala, Piedade; Fontiela, JoaoPortugal, located in the southwest region of the Eurasian plate, has been affected by several destructive earthquakes throughout its history, the most well-known being the 1755 Great Lisbon earthquake. The seismicity of the territory, both in the mainland and in the Azores and Madeira islands, has prompted the continuous development of seismic monitoring, from the first known macroseismic inquiry, following the 1755 Great Lisbon earthquake, to the current state-of-the-art seismic network. Once scattered in separate efforts, at present, most seismic stations in Portugal relay its data to a common data center, at Instituto Português do Mar e da Atmosfera, where data are automatically processed for the downstream generation of both manually revised and automatically generated products and services. In this article, we summarize the evolution of the permanent seismic network, its current status, the products and services that are publicly available, a recent effort of rapid deployment of a dense network following a mainshock, and state-of-the-art ocean-bottom seismometer developments.
- The Tagus River delta landslide, off Lisbon, Portugal. Implications for Marine geo-hazardsPublication . Terrinha, Pedro; Duarte, Henrique; Brito, Pedro; Noiva, João; Ribeiro, Carlos; Omira, Rachid; Baptista, Maria Ana Carvalho Viana; Miranda, Miguel; Magalhaes, Vitor; Roque, C.; Rosa, Marcos; Alves, Paulo; Teixeira, Francisco; Tagusdelta Cruise TeamThe stratigraphy of the Tagus river ebb-tidal delta off Lisbon (Portugal) is investigated using high resolution multichannel seismic reflection profiles with the purpose of searching for sedimentary or erosive features associated with landslides. The Tagus delta is sub-divided in two prograding seismic units of 17 ky to 13 ky and 13 ky to Present based on the calibration of seismic lines using gravity and box-cores in the Tagus pro-delta. We report the existence of a buried landslide with 11 km of length, 3.5 km of width and a maximum thickness of 20 m that accounted for the collapse of half of the upper unit of the Tagus river delta front in Holocene times. The non-collapsed half of the delta front contains extensive shallow gas of still unknown origin and nature. An estimated age of similar to 8 ky BP for the Tagus delta landslide is proposed based on stratigraphic correlation. The trigger mechanisms of the newly identified Tagus landslide are discussed as well as of the several landslides also found in the lower delta unit. These findings present a first step towards a future assessment of the susceptibility of the nearby coastal areas and the off-shore infrastructures to hazards related to such large collapses.
