Professional Stress in Relation to Anxiety, Depression and Irrational Beliefs Among Dental and Psychotherapy Students

Predisposing Factors for Recurrent Aphthous Stomatitis among Undergraduate Dental Students

Objectives The prevalence of recurrent aphthous stomatitis (RAS) among the general population worldwide is 20%. This study aims to discover any correlations between RAS predisposing factors and the gender and year of study of undergraduate dental students at the Faculty of Dental Medicine at Airlangga University.

Methods A cross-sectional analytical study using simple random sampling was performed. The respondents answered seven questions on a self-reported online questionnaire set up using Google Forms. Chi-square analyses were conducted to determine any correlation between RAS predisposing factors and the gender and year of study of the students.

Results The highest predisposing factors for RAS in undergraduate dental students were local trauma (77.7%) followed by stress (71.3%) and nutritional deficiencies (41.5%). Stress correlated strongly with the year of study (p = 0.015). There was no correlation between gender and RAS predisposing factors (p > 0.05).

Conclusion There was a correlation between stress, one of the predisposing factors for RAS, and the year of study, but there was no correlation between gender and RAS predisposing factors including local trauma, stress, nutritional deficiency, genetics, allergies, and systemic diseases.

The Impact of Chinese College Students' Perceived Stress on Anxiety During the COVID-19 Epidemic: The Mediating Role of Irrational Beliefs

Objective: To explore the underlying mechanism of the impact of perceived stress on anxiety of the Chinese college students during the COVID-19 epidemic. Methods: The Perceived Stress Scale, Irrational Belief Scale, and General Anxiety Scale were adopted in the current study. College students were randomly selected for online questionnaire survey. There were 1,598 valid questionnaires, and the proportion of women was 47.81%. Results: The perceived stress and anxiety, as well as the three dimensions of irrational beliefs (catastrophizing, low frustration tolerance, and depreciation) were significantly positively correlated; demandingness was not significantly correlated with anxiety. Further analysis found that the perceived stress had a significant positive predictive effect on the anxiety of college students. Catastrophizing, low frustration tolerance, and depreciation played part of the mediating role, and there was no significant difference in the strength of these mediating roles. Conclusion: The perceived stress of the COVID-19 epidemic had a positive effect on the anxiety of Chinese college students, this was partly mediated by irrational beliefs.
