Cognitive functioning is essential for handling both job and daily life. However, a cognitive failure characterised by self-perceived issues with focus, memory, decision-making, and clear thinking, is prevalent in both the general population and the working population and can be accompanied by both decreased well-being and job competence. Given the significance of people’s health, this study investigated the connection between sociodemographic factors and cognitive failures by conducting a cross-sectional study that involved 327 employees from the health department. Forgetfulness, Distractibility, and False Triggering were measured using a 25-item cognitive failure questionnaire. Information on sociodemographic and professional traits was obtained using the questionnaire. The association between cognitive failure and sociodemographic was established by descriptive analysis and a parametric test. The results of the cognitive questionnaire showed that most respondents (89%) had normal scores for cognitive function. A study using logistic regression found a link between Distractibility during sleeping, exercising, and residing with relatives. These findings may facilitate the development of effective strategies for preventing cognitive dysfunction and its negative effects on employees.
