- Digital health literacy: comparing factor structures of the portuguese eHEALS using confirmatory factor analysisPublication . Silva, Cláudia; Alves Lopes, António; Azevedo, Vitor Hugo; Lopes, Francisco; Ribeiro, Leonardo; Dias, TomásBackground and Objectives: Digital health literacy is essential for navigating digital health environments safely, particularly for future health professionals. Validated assessment tools are crucial for understanding competency levels and guiding educational interventions. This study evaluated the construct validity and internal consistency of the Portuguese version of the eHealth Literacy Scale (eHEALS) among health sciences students. Two models were tested using Confirmatory Factor Analysis (CFA): a unidimensional model and a second-order bidimensional model. Materials and Methods: A total of 375 undergraduate and postgraduate health sciences students (75.2% female, 23.2% male, 1.6% undisclosed) participated. CFA was performed to assess model fit using Chi-square divided by degrees of freedom (CMIN/DF), Root Mean Square Error of Approximation (RMSEA), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), Goodness-of-Fit Index (GFI), Root Mean Square Residual (RMR), and Akaike Information Criterion (AIC). Internal consistency was assessed via Cronbach’s alpha. Results: Both models demonstrated very good fit. The bidimensional model showed slightly better fit (CMIN/DF = 1.704, RMSEA = 0.043, CFI = 0.991, TLI = 0.985, RMR = 0.015, GFI = 0.983, AIC = 67.261) than the unidimensional model (CMIN/DF = 1.767, RMSEA = 0.045, CFI = 0.990, TLI = 0.983, RMR = 0.017, GFI = 0.980, AIC = 68.047). The chi-square difference test (Δχ² = 2.786, Δdf = 1, p = 0.095) indicated that both models were statistically comparable. Internal consistency was high (α = 0.868 total, 0.850 Factor 1, 0.743 Factor 2). Conclusion: The Portuguese version of eHEALS demonstrates good construct validity and internal consistency for assessing digital health literacy in higher education students. The bidimensional model, distinguishing between "Ability to Search for Online Health Information" and "Ability to Evaluate and Apply Health Information," provides a more detailed understanding of competency areas, helping to identify specific aspects for improvement and inform targeted educational interventions.
- Pressure injury on the face of patients undergoing noninvasive ventilation, hospitalized in the intensive care unitPublication . Viveiros, Abel; Nobrega, Júlio; Santos, Luisa; Pena-Otero, David; Costa, Ana; Ribeiro, Leonardo; Alves, AnaNoninvasive ventilation (NIV) implies some complications, being the lesion by pressure on the face the most frequente lesion associated to this practice in intensive care. Objectives: To determine the incidence of injuries caused by pressure on the face occurred in patients hospitalized in intensive care unit (ICU) of a hospital in the Autonomous Region of Madeira (ARM), submitted to NIV. Methodology: Retrospective study carried out between January and December 2017. Inclusion criteria: patients with age ≥ 18 years, hospitalized in the intensive care unit (ICU), exceeding 24 hours, with the introduction of NIV for an equal time and/or exceeding 2 hours and showing healthy skin on the face at the time of the admission. The data of 103 patients in our sample were collected from the database of patients with NIV in the ICU. Conclusion: The use of masks for single use, pressure relief and the application of sweet almond oil seems to have contributed to the reduction of lesion incidence on the skin which were caused by pressure (LSP) in patients submitted to NIV in the ICU.
