Background: This study aimed to examine the effect of individuals’ personality traits on the perceived effort.
Methods: This experimental study was conducted on 30 students via general health questionnaire (GHQ-28), Raven’s IQ test, Visual Analogue Scale (VAS), revised NEO personality inventory, and Jamar hand dynamometer (JHD).
Results: A significant positive correlation was found between the exerted force to the JHD (EF-JHD), and perceived effort rated on horizontal VAS (PE-H/VAS) and vertical VAS (PE-V/VAS) in the individuals with low levels of ‘neuroticism’. Considering ‘extraversion’ and ‘agreeableness’ factors of the NEO test, the correlation coefficient between EF-JHD, and PE-H/VAS and PE-V/VAS was higher in the individuals with medium levels compared to those with high levels. This relationship was reverse for the ‘openness to experience’ and ‘conscientiousness’ factors. The results demonstrated a significant strong positive correlation between PE-H/VAS and PE-V/VAS (r = 0.97). Multiple linear regression analysis revealed a moderate positive correlation between EF-JHD and PE-H/VAS and between EF-JHD and PE-V/VAS.
Conclusion: Individuals’ personality traits are recommended to be considered in assessing the perceived effort by VAS.

Background: Productivity plays a fundamental role in the global economy. Human resources are the most important factor, causing an increase or decrease in the productivity of an organization. Ergonomics is the scientific theory that studies the relationship between individuals and other elements of a system and the profession applies theories, principles, evidence, and methods to design to optimize human well-being and productivity of the organization. This study aims to investigate the effects of ergonomic features and anxiety on the productivity of office workers. Methods: In this descriptive-analytical cross-sectional study, 176 office workers (133 female and 43 male) of a university with three years of work experience were randomly selected. Data collection tools included demographic surveys, an inspection checklist, Rapid Upper Limb Assessment (RULA) checklist, the productivity measurement questionnaire, and Beck anxiety inventory. Results: The study results showed that 70% of workstations need to be changed through ergonomic interventions and changes. According to the results obtained from the linear regression model between productivity and working posture, anxiety, and work environmental factors, there is a positive relationship between working environment conditions and productivity (P=0.002). Conclusion: The main contribution of this research is that productivity should receive attention through changing working environment. The chairs are a vital element of an ergonomic and productive work office
