Abstract

One hundred and fifteen electronics factory employees completed questionnaires relevant to work stress, and gave unstimulated saliva samples. As previously found. Perceived Coping Incapacity correlated very significantly with self-reported emotional upset and psychosomatic complaints. Salivary [Na+] correlated significantly with Perceived Coping Incapacity (ϱ = −0.30, p < 0.01), and also with emotional upset (ϱ = −0.19, p < 0.05). Raised [K+] tended to be associated with reduced fatigue (ϱ = −0.21, p < 0.05) and lower self-medication (ϱ = −0.21, p < 0.05) together with a greater perceived personal work responsibility (ϱ = 0.19, p < 0.05) — all consistent with the perception of work demands as positive challenges rather than Stressors. Selfreported fatigue and emotional upset at work gave higher correlations with [K+] and [Na+] than either did on its own. Salivary [cortisol] was uncorrelated with self-reported work stress indices, and with [K+] and [Na+].
