This study examined the effects of scores on state anxiety on overall accuracy of performance and speed of working in a simulated pharmacy dispensing task. 75 undergraduates worked in a simulated pharmacy environment, designed by Schell and Grasha in 1998, to fill 42 mock orders for simulated pharmacy items. Participants' accuracy and work pace in the simulation, presimulation stress, and postsimulation perceived workload and state anxiety were measured. Analysis indicated that state anxiety and overall accuracy were strongly related. State anxiety appears to be one of the best predictors of errors in the simulated pharmacy dispensing task found so far, while the lack of relationship between work pace and accuracy was confirmed. Work pace predicted accuracy, indirectly, but only after statistically removing the effects of anxiety, task frustration, significant-other stress, and grade point average.
