The relationship between the psychosocial factors at work (psychological demands, decision latitude, and social support) and two aspects of mental load (Stress and Energy) was studied among 179 employees in a car body factory (137 men, 42 women). Regression analyses showed that Stress was positively correlated with Psychological demands, and Energy with Decision latitude. Shoulder and neck symptoms were more common among those who reported high stress; shoulder symptoms were also associated with high Psychological demands.
