The interactive effect of workplace stressors and mood on creativity and implementation activities: a dual level approach

Student thesis: Doctoral ThesisDoctor of Philosophy


This thesis analyses the impact of workplace stressors and mood on innovation
activities. Based on three competitive frameworks offered by cognitive spreading
activation theory, mood repair perspective, and mood-as-information theory, different sets of predictions are developed. These hypotheses are tested in a field study involving 41 R&D teams and 123 individual R&D workers, and in an experimental study involving 54 teams of students. Results of the field study suggest that stressors and mood interact to predict innovation activities in such a way that with increasing stressors a high positive ( or negative) mood is more detrimental to innovation activities than a low positive (or negative) mood, lending support to the mood repair perspective. These effects are found for both individuals and teams. In the experimental study this effect is replicated and potential boundary conditions and mediators are tested. In addition, this thesis includes the development of an instrument to assess creativity and implementation activities within the realm of task-related innovative performance.
