Spanish Validation of the Maastricht Acute Stress Test (MAST): A Cost-effective Stress Induction Protocol

The rise of stress studies has led to the existence of multiple stress induction protocols. However, cultural differences in stress reactivity are often overlooked. Therefore, this study aims to validate the Maastricht Acute Stress Test (MAST) in the Spanish population. A sample of 96 young adult participants was divided into an experimental group and a control group based on whether they were exposed to the MAST or a non-stressful control task. State anxiety and positive and negative affects were measured before and immediately after the protocol, while physiological stress (blood pressure and heart rate) was monitored throughout the experiment. The experimental group exhibited an increase in state anxiety, negative affect, and systolic and diastolic blood pressures after the MAST protocol. Participants with higher psychopathological risk presented higher scores of psychological stress than those with lower risk. Finally, it was found that participants with higher mathematical performance exhibited lower anxious reactivity following stressor exposure. Our results confirm the efficacy of the MAST and its validation for use in the Spanish population.
