“…Stress is often referred to as if it exists in the environment per se, although it is not typically an objective feature of a specific environment. Instead, stress reactivity consists of an individual’s perception of an environment and their reaction to it [3,4]. Some individuals are more prone to stress than others, thus enabling measurement of individual stress proneness via personality and other features as well as coping styles.…”

BackgroundExcessive stress has a negative impact on many aspects of life for both individuals and societies, from studying and working to health and well-being. Each individual has their unique level of stress-proneness, and positive or negative outcomes of stress may be affected by it. Technology-aided interventions have potential efficacy in the self-management of stress. However, current Web-based or mobile stress management solutions may not reach the individuals that would need them the most, that is, stress-sensitive people.ObjectiveThe aim of this study was to examine how personality is associated with stress among Finnish university students and their interest to use apps that help in managing stress.MethodsWe used 2 structured online questionnaires (combined, n=1001) that were advertised in the University of Helsinki’s mailing lists. The first questionnaire (n=635) was used to investigate intercorrelations between the Big Five personality variables (neuroticism, extraversion, openness, agreeableness, and conscientiousness) and other stress-related background variables. The second questionnaire (n=366) was used to study intercorrelations between the above-mentioned study variables and interest in using stress management apps.ResultsThe quantitative findings of the first questionnaire showed that higher levels of extraversion, agreeableness, and conscientiousness were associated with lower self-reported stress. Neuroticism, in turn, was found to be strongly associated with rumination, anxiety, and depression. The findings of the second questionnaire indicated that individuals characterized by the Big Five personality traits of neuroticism and agreeableness were particularly interested to use stress management apps (r=.27, P<.001 and r=.11, P=.032, respectively). Moreover, the binary logistic regression analysis revealed that when a person’s neuroticism is one SD above average (ie, it is higher than among 84% of people), the person has roughly 2 times higher odds of being interested in using a stress management app. Respectively, when a person’s agreeableness is one SD above average, the person has almost 1.4 times higher odds of being interested in using a stress management app.ConclusionsOur results indicated that personality traits may have an influence on the adoption interest of stress management apps. Individuals with high neuroticism are, according to our results, adaptive in the sense that they are interested in using stress management apps that may benefit them. On the contrary, low agreeableness may lead to lower interest to use the mobile stress management apps. The practical implication is that future mobile stress interventions should meaningfully be adjusted to improve user engagement and support health even among less-motivated users, for instance, to successfully engage individuals with low agreeableness.

“…Our aim is to explore whether the mindfulness intervention has a significant effect on the automatic nervous system in adolescence that can be detected with psychophysiological measures. Social and cognitive stress were induced by tasks that are loosely based on tasks commonly used in studies on physical (Carson et al, 2017; Määttänen et al, 2020) and mental health issues (Määttänen et al, 2019; Schwerdtfeger & Rosenkaimer, 2011).…”

The current pilot study examines the effects of a mindfulness intervention versus relaxation-based active control on psychophysiological reactivity measured by heart rate (HR), high-frequency heart rate variability (HF-HRV), skin conductance level (SCL), and number of skin conductance responses (SCR) in adolescents. A total of 110 students, ages 12 and 15, participated from four schools. The conditions of a 9-week mindfulness intervention or a relaxation-based active control were randomly assigned to schools. At the baseline (preintervention), participants completed a test protocol with three different tasks: an arithmetic task, a minimal stress task, and a social stress-inducing speech task, divided into argue, oppose, and comment subtasks. The test protocol was repeated postintervention at 9 weeks and followed up at 26 weeks. For the speech task (oppose), the number of SCRs increased in the control group during both (9-week and 26-week) follow-ups, but stayed at the same level in the intervention group (i.e., the stress response in the control group increased). Additionally, HR and SCL reactivity were close to significance, demonstrating an increase in the control group and increased stress. There were no significant differences in HR, HF-HRV, and SCL between the intervention and control groups. The results of this pilot study suggest that in a highly stressful social situation, mindfulness, compared to the active control, might have a subtle effect in lowering sympathetically driven physiological stress reactivity. Other measures show either no effects or tentative findings that should be addressed in future studies with larger samples.

Personality describes the average behaviour and responses of individuals across situations; but personality traits are often poor predictors of behaviour in specific situations. This is known as the "personality paradox".We evaluated the interrelations between various trait and state variables in participants' everyday lives. As state measures, we used 1) experience sampling methodology (ESM/EMA) to measure perceived affect, stress, and presence of social company; and 2) heart rate variability and 3) real-time movement (accelerometer data) to indicate physiological stress and physical movement. These data were linked with self-report measures of personality and personality-like traits.Trait variables predicted affect states and multiple associations were found: traits neuroticism and rumination decreased positive affect state and increased negative affect state. Positive affect state, in turn, was the strongest predictor of observed movement. Positive affect was also associated with heart rate and heart rate variability (HRV). Negative affect, in turn, was not associated with neither movement, HR or HRV.The study provides evidence on the influence of personality-like traits and social context to affect states, and, in turn, their influence to movement and stress variables.
