This thesis investigates the effectiveness of third-person self-talk (TPST) as a strategy for managing work-related stress using imaginary scenarios. Employing an experimental design, the impact of TPST on stress was compared to first-person self-talk and control conditions. Six subscales (Upset, Afraid, Nervous, Irritated, Distressed, and Alert) of the Positive and Negative Affect Schedule (PANAS) were used to measure negative affect, while trait anxiety was controlled using the State-Trait Anxiety Inventory (STAI) to control for its effect on the relationship between TPST and stress responses. Contrary to expectations, the findings did not support TPST's effectiveness in significantly reducing stress levels. Furthermore, trait anxiety appeared as a strong predictor influencing situational stress responses, indicating that TPST's effectiveness was limited compared to individual differences. Further research can explore TPST's applicability across cultures, using longitudinal or diary designs or distinguishing between self-talk of different natures (e.g., spontaneous and induced).
