- Assessment and impact of the risk of exposure of Portuguese biomedical scientists in the context of COVID-19Publication . Tavares, Ana Sofia R.; Bellém, Fernando; Abreu, Renato; Leitão, Céu; Medeiros, Nuno; Alves, Patrícia; Calmeiro, LuisCurrently, the main public health concern worldwide is the COVID-19 pandemic, caused by SARS-CoV-2, which was recently discovered and described. Due to its high pathogenicity and infectiousness, it is necessary to determine the risk healthcare professionals face every day while dealing with infected patients and contaminated biological samples. The purpose of this study was to assess Portuguese Biomedical Scientists' risk of COVID-19 exposure and related stress appraisals. One hundred and forty participants completed online versions of the WHO's Risk Assessment and Management of Exposure Survey and the Stress Appraisal Measure. Participants worked mainly in outpatient settings (45%), and in emergency services (28%). Twenty three percent of participants were exposed to COVID-19 through community exposure, and 39% through occupational exposure. Although 95% reported using personal protective equipment (PPE), 83.6% were at high risk of infection. However, the use of some types of PPE was related to the risk of exposure. Participants reported moderate perceptions of stress and threat, but also moderate perceptions of control over the situation. These results may contribute to a more efficient risk management of these professionals and prevent disease transmission in hospitals and communities.
- Determinants of the intention to use performance-enhancing substances among portuguese gym usersPublication . Tavares, Ana Sofia R.; Rosado, António; Marôco, João; Calmeiro, Luis; Serpa, SidonioThe purpose of this study is to examine the determinants of the intentions to use prohibited performance-enhancing substances (PES) and to test the Theory of Planned Behavior's usefulness in predicting self-reported PES use in both genders. A convenience sample of Portuguese gym users (n = 453) completed an anonymous web-based survey. Structural equation modeling, multigroup analysis, and t-test with the Welch correction for heterokedastic variances were used. At the structural level, results support attitudes, beliefs, and subjective norms in predicting intentions to PES use in gym users, with subjective norms being its strongest predictor. Moreover, results showed a significant association between self-reported PES use and intentions to use. The predictive model was invariant across genders; however, compared to males, females believed less in the performance-enhancing effects of PES, were less prone to the influence of significant others, and had weaker intentions to use these substances. Psychological strategies should be based on subjective norms, alongside beliefs and attitudes, toward PES use as these variables influence the intention to use PES in this particular population.
