Sumario:OBJECTIVES: We aimed to explore the relationship between objective cognitive functioning and work performance among Japanese workers. METHODS: From February to November 2019, this cross‐sectional study enrolled workers aged 18–65 years from 10 companies located in a metropolitan area of Japan. We emailed invitations to participate to employees of companies that had agreed to cooperate with the study. We measured work performance with the question, “How would you rate your performance (compared with your optimum performance) over the past 4 weeks?” Responses were made via a visual analog scale (range: 0–100). Cognitive functioning was assessed using the THINC‐integrated tool (THINC‐it®). THINC‐it® is a brief, objective computerized cognitive assessment battery. Associations between work performance and cognitive functioning tests were examined using logistic regression analysis. RESULTS: In total, 353 individuals provided e‐consent to participate, of whom 276 were included in the analysis (after omitting those with missing values). The median work performance was used to divide participants into high‐ (scoring ≥ 80%) and low‐ (scoring < 80%) performing groups. The P‐values for trends indicated that association between cognitive domains, such as attention, executive functioning and working memory was significant (P < .05). Work performance was significantly associated with cognitive function for the two tests that assess attention, executive functioning, and working memory in general workers. CONCLUSIONS: Our results suggest that objective cognitive functioning may be related to work performance. Longitudinal investigations may allow for the establishment of causality.
