Based on Occupational Stress Indicator-2 in Chinese version and semi-structured interview, a
study of 297 employees from a bank, a company and a nuclear power plant contributes to
generalizability of work stress theories. By hierarchical regression, results show that job
satisfaction, leave intention, psychological and physical well-being are significantly predicted by
different stressors. And, there is evidence that negative affectivity (NA) plays different role in
different stressor-job satisfaction relationship: hyper-responsibility mechanism through which NA
might affect relationships-strain relationship, perception mechanism through which NA might
affect home/work balance-strain relationship, etc.. Further, some validation data for OSI-2 are
provided in Chinese sample.

2095.1 Trust in risk regulation: Cause or consequence of the acceptability of GM food? Wouter
Poortinga, Nick F. Pidgeon, Centre for Environmental Risk, UK
Although there is evidence that trust is strongly related to the perceptions of risk, it is less clear
what the direction of these relationships is. In this study two models of trust are compared. It is
investigated whether trust is the cause or the consequence of the acceptability of GM food. Results
from three studies on GM food were more supportive of the associationist view than of the causal
chain account of trust. In line with the associationist perspective, affect accounted for a large
portion of the variance between perceived risk, perceived benefit, trust in risk regulation and
acceptability.

To study caffeine and/or placebo suggestion as countermeasures during sleep deprivation (SD).
Six health males volunteered for the within-subjects and counterbalanced design study during 30h
SD and received information about scientifically proven effects of caffeine. Except control group,
twice 200-mg caffeine or once 200-mg caffeine and 200-mg placebo were administered at 12:00
and 4:00, respectively in the other two groups. The alertness was assessed with Letter Cancellation
Test. Numbers of cancelled letters of two treatment groups were more than that of control group
