Salivary Alpha-Amylase and Behavior Reaction in Acute Stress and the Impact of Tridimensional Personality
Background: Understanding individual differences of these indexes in response to stress is important for developing effective interventions. The Tridimensional Personality Questionnaire (TPQ), which has three dimensions, may reflect such individual differences. Meanwhile, there is increasing interest in the relationship between mental stress and non-invasive markers. Objectives: We examined whether these three dimensions were associated with cognitive behavior tests and the related sAA responses. Methods: All subjects were divided into different groups based on the scores of the TPQ measuring temperament dimensions. Patterns of Stroop combined with mental arithmetic stress tests were presented, and the sAA responses were recorded as the index of stress responses, and compared between groups. Results: The sAA levels in the post stress test and the recovery period of the high reward-dependence (RD) group were significantly greater than in the low-RD group. The number of trials of Stroop in the high novelty-seeking (NS) group was significantly greater than in the low-NS group. Conclusions: Individual differences in TPQ personality traits may be associated with different patterns of stress responses.
