Objective: This paper presents the cross-cultural adaptation to Portuguese of the Dissociative Experiences Scale, the worldwide most employed questionnaire for screening and quantifying dissociative phenomena.

Methods: Two translations and their respective back-translations were performed, as well as the evaluation of the semantic equivalence, the preparation of the synthetic version, the pre-testing on the target population, the definition of the final version and a second pre-testing on the target population.

Results: A high level of semantic equivalence between the original instrument and the two pairs of translations and back-translations was observed regarding the referential and general meanings. The two pre-testing in the target population led to alterations in order to achieve the semantic and operational equivalence criteria.

Conclusion: This work provides the first adaptation of a specific instrument to detect and quantify dissociative symptoms in the Brazilian context.

The Democratic Republic of the Congo (DRC) struggles with low full childhood vaccination coverage (around 50 %) and a high children-under-five mortality rate (79 deaths per 1000 live births). This situation is potentially exacerbated by vaccine hesitancy, which was identified by the World Health Organization (WHO) as one of the top 10 global health threats in 2019. To gain deeper insights into levels of vaccine confidence possibly influencing vaccination coverage, we explored perceptions and attitudes towards childhood and adult vaccines in Boende (Tshuapa province, western DRC), which experienced an Ebola outbreak in 2014 and hosted the EBL2007 Ebola vaccine trial (2019-2022).

Article Synopsis
  • Foodborne diseases are a major global health issue, often due to improper food handling, and this study investigates the knowledge, attitudes, and hygiene practices of food handlers in Yeka Sub-city, Addis Ababa, Ethiopia.
  • A survey of 373 food handlers showed good overall knowledge (65%) and positive attitudes (92.2%) toward food safety, but poor hygiene practices (44%) and gaps in understanding disease transmission, particularly for diseases like Hepatitis A and tuberculosis.
  • Factors such as marital status, food safety experience, and job satisfaction influenced the food handlers' knowledge, attitudes, and practices, indicating a need for improved education and consistent hygiene measures in food service establishments.
