Task performance is frequently stressful, especially when the task imposes high cognitive demands. Research has shown that the subjective stress response to performance is multidimensional. Different types of task demand elicit different patterns of response. This chapter reviews the use of the Dundee Stress State Questionnaire (DSSQ: Matthews et al., 2002) in the investigation of task -induced stress. The DSSQ is based on a factor model that differentiates 11 primary state factors, which cohere around three higher-order dimensions of task engagement, distress and worry. Following a review of the psychometric evidence for this factorial structure, the chapter surveys evidence on the differing profiles of state change produced by a range of basic and applied performance tasks. It als o reviews evidence that links stress states to cognitive appraisal and coping processes, consistent with the transactional model of stress. Data also show that the DSSQ factors predict objective performance. These findings may be understood in relation to the emerging cognitive neuroscience of attention. The final section of the chapter covers practical issues in using the DSSQ for assessment of stress in basic and applied contexts.
