Exploring the correlation between certain psychological factors and cognitive abilities among central control room operators in a western Iranian oil field: A fitting trial study in ergonomics

BACKGROUND: Employees in high-stakes environments, such as central control rooms in oil fields, face various psychological factors that can covertly impact their cognitive performance. This study aims to investigate the relationship between specific psychological factors and cognitive abilities among these operators. MATERIALS AND METHODS: This fitting trial study in ergonomics is done among 24 central control room operators participated, which employed five questionnaires—GHQ, RTLX, OSIPOW, ESS, and PSQI—alongside cognitive performance testing software (IVA-2) to evaluate participants’ perceptions and performance. Data analysis was performed using R-Studio version 2023.06.1, with a significance level set at 5% for various statistical tests. RESULTS: The findings revealed no significant differences in questionnaire scores based on marital or smoking status. However, weight significantly influenced Pittsburgh Sleep Quality Index scores ( P = 0.034), while the number of children correlated with the RTLX questionnaire scores ( P < 0.001). Age also impacted the Epworth Sleepiness Scale scores ( P = 0.016). Cognitive performance indicators were higher in the morning compared with evening and night shifts, with a significant decline in cognitive functions over time ( P < 0.001). Correlations between cognitive performance and OSIPOW questionnaire scores were noted. CONCLUSION: The research highlights the critical role of sleep quality, overall health, work-related stress, and mental workload in shaping cognitive performance among control room operators. These findings emphasize the need for comprehensive health initiatives aimed at mitigating the negative effects of shift work to enhance cognitive abilities and workplace safety.
