Abstract

Abstract: Background: Negative beliefs about stress (e.g., "stress is bad") constitute an independent risk factor for increased morbidity and mortality. One potential underlying mechanism are altered responses to acute psychosocial stress. The aim of this study was to investigate whether beliefs about stress are associated with physiological and endocrine stress response patterns. Methods: A total of N = 77 healthy adults were randomised to an experimental and a placebo control group and were subsequently exposed to the Trier Social Stress Test (TSST). Stress beliefs were measured before and after a psychological manipulation aiming at fostering more balanced stress beliefs or a placebo manipulation. Self-reported stress was measured four times before/after the TSST, heart rate was assessed continuously, and cortisol was assessed eight times before/after the TSST. Results: There was a significant decrease in negative stress beliefs ( p < .001) and increase in positive stress beliefs ( p < .001) in participants in the experimental condition, which was absent in participants in the placebo condition. The participants in the experimental group had more pronounced self-reported stress reactions ( p = .028) while at the same time also showing more pronounced stress recoveries ( p = .036). The findings regarding cortisol were mixed. Conclusions: More balanced stress beliefs appeared to be associated with more efficient subjective responses to acute psychosocial stress. These findings attest to a potential mechanism translating negative stress beliefs into ill health while at the same time outlining targets for psychological interventions. Highlights: Our brief intervention significantly reduced negative stress beliefs. This was associated with altered emotional stress reactivity and recovery. The evidence was mixed regarding altered endocrine stress recovery.
