- Attitude Towards Pressure Ulcers Instrument: validação e adaptação transcultural para a população portuguesa de enfermeirosPublication . Batista, Margarida; Dixe, Maria dos Anjos; Alves, PauloContexto/objetivos: A investigação e a prática têm evidenciado a importância das atitudes dos enfermeiros na prevenção das úlceras de pressão e a necessidade da elaboração de instrumentos de medida válidos e fiáveis para a sua avaliação. Respondendo a esta necessidade, procedemos à validação transcultural do Attitude Towards Pressure Ulcers Instrument (APU) para a população portuguesa. Metodologia: Realizou-se um estudo metodológico numa amostra não-probabilística de estudantes de enfermagem (n=147) e enfermeiros (n=155). Foi utilizada a metodologia usada no estudo de validação original. Resultados: A tradução-retrotradução com a participação de um painel de peritos garantiu a equivalência semântica e conceptual. A análise fatorial determinou que os 22 itens se organizam em 5 fatores (importância, responsabilidade, obstáculos/barreiras, confiança na eficácia e competências pessoais), explicando 53,6% da variância total. Obteve-se um poder descriminante da escala em alguns dos grupos comparados. O coeficiente a Cronbach total=0,847 garantiu a consistência interna da escala e a confiabilidade teste-reteste revelou coeficientes de correlação r=0,883 comprovando a sua estabilidade temporal. Enfermeiros e estudantes revelaram uma atitude positiva acerca dos itens da escala, sem diferença estatisticamente significativa entre estes (t=0,567; p>;0,05). Conclusão: A escala APu-PT evidenciou ser fiável e válida para a prática, ensino e investigação.
- Comfort-promoting interventions for the elderly in hospital settingsPublication . Marques, Rita; Dixe, Maria dos Anjos; Sousa, Patrícia PontíficeBackground: The comfort of the elderly in hospital settings requires special attention from the health care professionals involved, particularly nurses, since hospitalization often generates suffering and discomfort. In such contexts, it is essential to consider the specific characteristics of the elderly, taking into account their life experiences and their needs, to promote the health, well-being, and comfort of this population. Hence, the present work aimed to explore the nursing interventions that promote comfort among the elderly in hospital settings. Methods: A mixed descriptive exploratory study was conducted through the application of a questionnaire, using intentional non-probabilistic sampling. The study encompassed 55 elderly individuals hospitalized in the medical service of a public hospital located in Lisbon. Results: The results show that the participants perceived a reasonable level of comfort (5.65 ± 6.46). The following categories emerged from the content analysis: (1) physical interventions; (2) psycho-spiritual interventions; (3) socio-cultural interventions; and (4) environmental interventions. Conclusions: These findings help to understand comfort-promoting nursing interventions in the studied population. It was concluded that, to improve care quality, comforting interventions should focus on the elderly patient’s individuality, through support activities, empowerment, and the preservation/correction of the surrounding environment. Additionally, the provided care should be based on the real needs, expectations, preferences, and values of the elderly individual.
- Development and validation of a comfort-measuring scale for elderly individuals with chronic conditionsPublication . Marques, Rita; Veludo, Filipa; Sousa, Patrícia Pontífice; Dixe, Maria dos AnjosBackground: Ageing is associated with chronic diseases and successive losses, which affect the comfort experienced by the elderly. Hence, in that population, comfort must be viewed as a need, and health care professionals (particularly nurses) should promote it through their interventions. This work aimed at developing a scale to assess comfort in elderly individuals with chronic conditions and determining the aforesaid scale’s psychometric characteristics (validity and reliability), while ascertaining the comfort levels experienced by the participants. Methods: Our sample comprised 454 chronically ill elderly individuals, either hospitalized, or in residential care/at home. As regards descriptive statistics, we calculated various summary measures. Validity was appraised via exploratory factor analysis, considering the main components. We performed varimax rotation and factor extraction (in which factors with eigenvalues > 1 were extracted). Reliability was established by calculating internal consistency, using Cronbach’s alpha. For each scale item, we examined the corrected item-test correlation. Additionally, we calculated skewness and kurtosis, also carrying out a confirmatory factor analysis. Results: The exploratory factor analysis produced a scale with 38 items and five factors, which fitted the data and explained a variance of 61.355%. The values of the Kaiser-Meyer-Olkin test and the Bartlett’s test (sphericity) were 0.943 and 12055.962, respectively (both with p < 0.001). Our model was substantiated by the confirmatory factor analysis (χ² = 2884.242; df = 660; RMSEA = 0.086; CFI = 0.811; TLI = 0.798; SRMR = 0.066) and the Cronbach’s alpha coefficient was 0.959. The summary measures showed that, overall, the participants experienced good comfort levels (Mean = 3.64; SD = ±0.676), revealing higher comfort levels in the “Spirituality and meaning of life” dimension (Mean = 3.79; SD = ±0.742) and lower comfort levels in the “Normality of life” dimension (Mean = 3.39; SD = ±0.922). Conclusion: The scale demonstrated suitable psychometric properties, ensuring its validity and reliability in assessing comfort in elderly individuals with chronic conditions. Its five-factor structure enables a comprehensive evaluation, highlighting key comfort dimensions. These findings support targeted interventions, aiding healthcare professionals in improving care and informing evidence-based practices and health policies to enhance well-being. Implications for nursing and health policy: By measuring comfort levels in chronically ill elderly individuals, it is possible to plan/improve the comforting care provided by the involved professionals (namely nurses). Clinical trial number: Not applicable.

- Programas de educação dirigidos ao utente com diabetes mellitus tipo 2: revisão sistemática da literaturaPublication . Menino, Eva; Dixe, Maria dos Anjos; Louro, Maria Clarisse Martins; Roque, Sofia Maria BorbaO aumento da longevidade e as problemáticas de saúde associadas ao aumento da incidência da doença crónica, concretamente a diabetes que apresenta implicações documentadas ao nível económico, social e familiar, justificam a necessidade de uma resposta dos serviços de saúde consertada e de qualidade. Esta revisão sistemática tem como objetivo analisar os programas de educação dirigidos ao utente diabético, metodologias de avaliação assim como os respetivos resultados. Os cinco estudos incluídos resultaram duma pesquisa realizada na EBSCOhost e na ISI Web of Knowledge. Os programas de intervenção apresentam metodologias e estruturas distintas, embora todos tenham tido por base teórica a educação para a autogestão. As metodologias de avaliação da eficácia dos programas incidiram essencialmente em parâmetros fisiológicos, embora em alguns estudos tenham sido avaliados parâmetros psicológicos. Os resultados mostram melhorias nos valores da Hemoglobina glicada; da pressão arterial, colesterol, na vigilância oftálmica, autovigilância dos pés e vigilância nefropática, autoeficácia, qualidade de vida, dieta, peso corporal, perímetro abdominal, indicadores de atitude e indicadores de comportamento. Parece haver uma resposta positiva aos programas de intervenção, traduzida em resultados relacionados com parâmetros fisiológicos e parâmetros psicológicos.
- Psychological impacts of the COVID-19 pandemic among portuguese and swiss higher-education students: protocol for a mixed methods studyPublication . Querido, Ana; Aissaoui, Djamel; Dixe, Maria dos Anjos; Schwander-Maire, Françoise; Cara-Nova, Tanya; Charepe, Zaida; Laranjeira, CarlosBackground: Higher-education students are particularly vulnerable to both everyday stressors and mental health problems. Public health emergencies may generate a range of unforeseen potential stressors for vulnerable individuals and communities. The current pandemic has apparently led to an increase in psychiatric symptoms among these students. Objective: The goal of this study is to characterize the psychological impact of the COVID-19 pandemic among Portuguese and Swiss higher-education students. Methods: This project will use a mixed methods sequential explanatory design in Portugal and Switzerland, with two consecutive phases. During Phase I, a quantitative study will assess the psychological responses of higher-education students during the COVID-19 pandemic. A convenience sampling method will be used for collecting information from students. The association between variables will be determined with univariable and multivariable analyses. During Phase II, qualitative data will be collected in order to understand the determinants of psychological stress and the strategies adopted by students as a result of the COVID-19 pandemic, as well as to identify their opinions and feelings about the teaching-learning process during quarantine. In this phase, participants will be selected using a maximum-variation sampling method. Data from focus group discussions will be coded and inductively analyzed using a thematic analysis approach. Finally, quantitative and qualitative results will be merged during interpretation to provide complementary perspectives. Results: This paper describes and discusses the protocol for this mixed methods study, which will be completed in December 2021. This study was formally approved by the local ethics committee (CE/IPLEIRIA/22/2020) in Portugal and authorized by the Swiss Association of Research Ethics Committees, swissethics (CER-VD-2020-02889). Conclusions: This research can contribute to the development of teaching tools and methods that reinforce positive mental health strategies, hope, and adaptive coping among students, and to the development of a class on mental health interventions in the context of catastrophic and traumatic events. This project will also help government stakeholders as well as health and education professionals safeguard the psychological well-being of students facing an expanding COVID-19 pandemic.
- Revalidation of the Holistic Comfort Questionnaire – Family for caregivers of people with advanced chronic diseasePublication . Marques, Rita Margarida Dourado; Dixe, Maria dos Anjos; Querido, Ana Isabel; Sousa, Patricia PontificeBackground: Comfort is essential in nursing practice, so useful and valid assessment tools are required. Objectives: To analyze the psychometric properties of the Holistic Comfort Questionnaire – Family (HCQ-F) for the Portuguese population and assess the level of comfort among caregivers of people with advanced chronic disease. Methodology: A methodological study with a quantitative approach was conducted with 314 caregivers. The psychometric properties were analyzed using descriptive summary measures, item-total correlations, and Cronbach’s alpha. Factor analysis was performed using varimax orthogonal rotation and extraction factors with eigenvalues > 1. Results: The internal consistency and factor analysis of the HCQ-F items resulted in the Holistic Comfort Questionnaire – Caregivers – Portugal (HCQ-C-PT) with 18 items that were distributed by 3 factors: relief, ease, and transcendence (α=.795). Conclusion: Based on validity and reliability results, the HCQ--C-PT proved to be suitable for assessing comfort in caregivers of people with advanced chronic disease.
- The fear of falls in the caregivers of institutionalized eldersPublication . Baixinho, Cristina Lavareda; Dixe, Maria dos Anjos; Henriques, Maria Adriana; Marques-Vieira, Cristina; Sousa, LuísAIMS: To understand how the fear of falls emerges and manifests itself in caregivers of institutionalized elders. METHOD: It is a qualitative study, based on the Grounded Theory and carried out with 24 informal caregivers, 5 nurses, 2 physicians and 2 directors of two Portuguese nursing homes. Data collection took place through interviews, participant observation, and documentation analysis, between October 2016 and January 2018. Data was collected and analyzed simultaneously, following the stages of open, axial, and selective coding. RESULTS: The comparative analysis of the findings identified the conceptual category "Fear of falls in the caregivers of institutionalized elders". The main category is associated with the categories: maintaining safety, hidden fear of falls, the perceived self-efficacy in the prevention of falls, falls and interpersonal relations, previous experiences, and team support. CONCLUSIONS: The fear has an influence on the self-efficacy perceived in the prevention of falls; the quality of the teamwork, in turn, is affected by previous negative experiences and by the support of the team.
