Therefore, the current study investigates how worry cross-sectionally and prospectively relates to (components of) burnout and tests whether this relation is moderated by gender. Data of self-reported measures in a longitudinal study of 516 participants were analyzed using multiple regression analyses. Our data show a strong, positive cross-sectional relation between the level of pathological worry and the severity of burnout symptoms. However, the course of burnout symptoms was best predicted by burnout symptoms at baseline and worry did not additionally predict burnout symptoms. Moreover, the components emotional exhaustion and lowered professional efficacy were related to worry, whereas cynicism was not related. Additionally, the study could not confirm that gender moderates between worry and burnout. It can be concluded that the level of pathological worry and (two components) of burnout are positively related. Yet this association is not moderated by gender. A limitation of this study is that the measurements were based on self-reported inventories in an uncontrolled environment. Our findings strengthen the model of PC and create a basis for further research. An opportunity for future research is to further study the relation of worry in somatic and psychological health. Finally, future research could address the prospective relation of pathological worry of the severity of burnout symptoms in a clinical sample, since this relationship has not been researched yet.Show less

Previous studies suggest that health anxiety and neuroticism are important determinants of the behavioral and cognitive response to the virus. Method: The current study investigates these determinants during the beginning of the new coronavirus outbreak using longitudinal questionnaire data derived from the LISS panel. In a sample of Dutch participants (N = 2903), we tested the hypotheses that neuroticism and health anxiety predicted the corona response. Results: Regression analyses showed that higher health anxiety – assessed 6 years before the pandemic - was a predictor of more preventive behaviors and perceived risk. Contrary to the hypothesis, neuroticism was not associated with preventive behavior and risk perceptions. Exploratory analyses showed that higher agreeableness, extraversion, being a woman, and higher education predicted more preventive measures. Furthermore, being a woman and of lower age predicted a higher risk of infection cognitions. Limitations: These findings only shed light on the initial response to the threat of a new, unknown pandemic in the Dutch population. Furthermore, the study did not measure the effect of determinants on harmful behaviors or cognitions. Conclusion: Individual differences play a vital role in the behavioral and cognitive response at the beginning of the pandemic. Tailored interventions can target men, low health anxiety, lower educated, low agreeable, more introverted persons to promote preventive measures and slow down the spreading of a virus.Show less

In addition, research shows attentional control (AC) also moderates threat-related AB, counteracting the moderating role of anxiety. Angelidis, Hagenaars, van Son, van der Does, and Putman (2018) and Van Son, Angelidis, Hagenaars, van der Does, and Putman (2018) conducted dot-probe studies testing AB towards different threat stimuli on healthy participants and observed partially incongruent results. Research objective: This project aimed at firstly testing the moderating roles of trait anxiety and AC on AB towards different threat stimuli individually and secondly testing the moderating role interactively. Methods: 52 healthy students completed a self-report trait-anxiety and AC questionnaire. Additionally, AB was tested by letting the participants complete a dot-probe task with neutral, mild, and high threat level stimuli. Results: The moderating roles of trait anxiety and AC could only be partially confirmed with trait anxiety moderating vigilance towards mild threat and AC moderating vigilance towards high threat. However, trait anxiety and AC did not interactively moderate ABs to different threat levels. Discussion and conclusion: Individual differences in AC along with stimulus threat level importantly moderate anxious AB and need to be considered in future studies.Show less

However, the remission rate is not optimal for adults with an anxiety disorder, which could be due to non-response or to the return of the original fear after exposure therapy. Persons with high levels of anxiety have more difficulties constructing and consolidating extinction memories. Stimulating the vagus nerve (tVNS) is a promising method of enhancing the process of extinction learning as shown in previous animal and human studies. AIM: The aim of this study was to assess whether participants with high levels of anxiety would benefit more from the addition of tVNS measured in US expectancy ratings and skin conductance response. METHOD: This paper is a reanalysis of the data from the study of Burger et al. (2018). In this study healthy humans participated in a prepared fear learning paradigm, spider pictures were used as conditioned stimulus. After the acquisition phase participants were randomly allocated to the tVNS condition (N=42) and to the sham condition (N=43) for the extinction phase. High- and low-scoring groups were created based on the state and trait subscales of the STAI. RESULTS: There were no differences found between the high- and low-scoring groups in the effectiveness of tVNS, although the low state group in the tVNS condition showed lower US expectancy ratings for the CS- trials. CONCLUSION: This distinct study does not provide conclusive evidence to support the direction of studying tVNS in a clinical sample.Show less
