- Chemical safety in academic laboratories: awareness, attitudes, and practices among higher education studentsPublication . Ribeiro, Inês; Ramos, Catarina; Santos, Joana; Carvalhais, Carlos; Santos, Joana; Alberto Alves Carvalhais, CarlosHigher education institutions, particularly those with teaching and research laboratories, play an important role in transmitting knowledge and attitudes regarding chemical safety to their students. As such, this study aims to assess the knowledge and attitudes of higher education students across different study programs regarding laboratory chemical safety. A cross-sectional study was conducted using a questionnaire adapted and translated into Portuguese. The instrument comprised twenty-seven questions and was distributed to students enrolled in undergraduate and graduate programs that include laboratory practices in their curricula in March and July of 2025. A total of 284 students participated in the study, divided among the different study programs (CTeSP = 4.2%; Bachelor’s = 70.4%; Master’s = 21%; Doctorate = 4.2%). The results showed that, although a large percentage of students have a high level of knowledge, their attitudes are not always the most appropriate, which could jeopardize their safety and that of those around them. Our findings revealed that there is room for curriculum adjustments. Early exposure to chemical and laboratory safety concepts can promote the development of students’ awareness and future professionals’ competence. Integrating safety modules into education may enhance knowledge and skills for making informed decisions that reduce accidents/incidents in laboratory environments.
- Portuguese version of the Swedish Occupational Fatigue Inventory (SOFI) among assembly workers: Cultural adaptation, reliability and validityPublication . Santos, Joana; Alberto Alves Carvalhais, Carlos; Ramos, Catarina; Coelho, Tiago; Monteiro, Pedro; Vaz, MárioObjectives: Reliable and valid instruments are essential for understanding fatigue in occupational settings. This study analyzed the psychometric properties of the Portuguese version of the Swedish Occupational Fatigue Inventory (SOFI). Material and Methods: A cross-sectional study was conducted with 218 workers from an automotive industry involved in assembly tasks for fabrication of mechanical cables. Convergent and discriminant validity, internal consistency reliability and confirmatory factor analysis were performed. Results: Results showed adequate fit to data, yielding a 20-item, 5-factor structure (all intercorrelated): Chi2 /df (ratio Chi2 and degrees of freedom) = 2.530, confirmatory fit index (CFI) = 0.919, goodness of fit index (GFI) = 0.845, root mean square error of approximation (RMSEA) = 0.084. The SOFI presented an adequate internal consistency, with the sub-scales and total scale presenting good reliability values (Cronbach’s α values from 0.742 to 0.903 and 0.943 respectively). Conclusions: Findings suggest that the Portuguese version of the SOFI may be a useful tool to assess fatigue and prevent work-related injuries. In future research, other instruments should be used as an external criterion to correlate with the SOFI dimensions.
- Psychometric properties of the portuguese version of the occupational fatigue exhaustion/recovery (OFER) scale among industrial shift workersPublication . Santos, Joana; Ramos, Catarina; Silva, André; Amorim, Sara; Winwood, Peter; Alberto Alves Carvalhais, CarlosReliable and valid instruments are essential for understanding fatigue in occupational settings. This study analyzed the psychometric properties of the Portuguese version of the Occupational Fatigue Exhaustion/Recovery (OFER). A cross-sectional study was conducted with 260 workers (M = 46.52 ± 13.16 years) from a textile industry, exposed to shift work. Convergent and discriminant validity, internal consistency reliability and exploratory and confirmatory factor analysis were performed. Results showed an adequate fit to data (χ2 (84) = 209,102, CFI = 0.936, GFI = 0.902, RMSEA = 0.076 CI90% (0.063–0.089)), yielding a 13-item, three factor structure. Two items were removed due to low factor loading. The OFER presented an adequate internal consistency, with the subscales presenting good reliability values (Chronic Fatigue (α = 0.81), Acute Fatigue (α = 0.84) and Recovery between Shifts (α = 0.77)). Findings suggest that the Portuguese version of OFER can be a useful tool to assess occupational fatigue of shift workers and prevent work related injuries.
