GONZALEZ MUNOZ, ELVIA LUZ and GUTIERREZ MARTINEZ, RODOLFO E. MENTAL WORKLOAD AS A STRESS RISKFACTORIN WORKERS FROM THE ELECTRONICS INDUSTRY. rev.latinoam.psicol. [online]. 2006, vol.38, n.2, pp. 259-270. ISSN 0120-0534.
The purpose of the present study was to determine how some individual, organizational and ergonomic factors influence work stress and mental workload. Participants were 95 workers (male and female) from an electronics organization located in the metropolitan area of the city of Guadalajara, México. Ergonomic conditions were evaluated through the Ergonomics Evaluation List (OIT); Mental work load was analyzed with the NASA-TLX (Hart Staveland, 1988) and stress was measured with the SWS-Survey (Gutiérrez Ostermann, 1994). Odds Ratio was obtained for each variable as risk factor for work stress and a logistic regression was conducted with those risks that were significant. Results show that work schedule, mental demand, temporary demand and frustration on the task can be considered as risk factors for work stress.
