Key result
Relaxing breathing and biofeedback improved cardiac coherence during anticipatory stress, with greater effectiveness in individuals presenting higher scores of openness to experience.
Why the study?
The study aimed to investigate the influence of personality on both anticipatory stress vulnerability and the effectiveness of coping strategies in a real-life context.

Personality traits, particularly neuroticism and openness, significantly influence anticipatory stress vulnerability and the effectiveness of brief coping interventions like relaxing breathing and biofeedback in medical residents.
Supports breathing/biofeedback for anticipatory stress in residents; extends evidence that openness moderates efficacy.
Objective: The present study aimed at investigating the influence of personality on both anticipatory stress vulnerability and effectiveness of coping strategies in a real-life context. Methods: Following assessment of individual personality traits (Big Five Inventory), 147 volunteers were exposed to the anticipation of a stressful event. Anxiety and cardiac reactivity were assessed as markers of vulnerability to anticipatory stress. Then, participants were randomly assigned to three groups and subjected to a 5-min intervention: relaxing breathing, relaxing breathing combined with cardiac biofeedback, and control. The effectiveness of coping interventions was determined through the cardiac coherence score achieved during the intervention. Results. Higher neuroticism was associated with higher anticipatory stress vulnerability, whereas lower conscientiousness and extraversion were related to lower anticipatory stress vulnerability. Relaxing breathing and biofeedback coping interventions contributed to improve the cardiac coherence in all participants, albeit with greater effectiveness in individuals presenting higher score of openness to experience. Conclusions. The present findings demonstrated that personality traits are related to both anticipatory stress vulnerability and effectiveness of coping interventions. These results bring new insights into practical guidelines for stress prevention by considering personality traits. Specific practical applications for health professionals, who are likely to manage stressful situations daily are discussed.

Schlatter et al. (2022) conducted an RCT in Anticipatory stress (n=147). Relaxing breathing and cardiac biofeedback vs. Control (common professional activity) was evaluated on Cardiac coherence score (interaction with openness trait for relaxing breathing) (β 65.13, p=0.010). Relaxing breathing and biofeedback improved cardiac coherence during anticipatory stress, with greater effectiveness in individuals presenting higher scores of openness to experience.
