Association between dental environment stress and sense of coherence in dental students: a cross-sectional study

ABSTRACT

Abstract The aim of this study was to explore associated variables with sense of coherence (SOC), and dental environment stress (DES) in a sample of dental students. All undergraduate (n = 474) and graduate (n = 105) dental students enrolled in the first semester of 2020 at a public university in southern Brazil were invited to participate. Data collection was performed by an online questionnaire, which included information related to sociodemographic and educational characteristics, biopsychosocial factors, aspects related to feelings experienced in the COVID-19 pandemic, and the SOC scale. The study outcome (DES) was measured by a validated tool. Linear regression analyses were performed to identify the associations between the outcome and all independent variables. A total of 408 students were included (response rate 70.5%). The overall mean score of the DES scale was 73.95 (SD 24.13). Students with higher SOC scores were observed to have significantly lower DES scores (βGRADUATE -0.376; 95% -0.482 to -0.271; βUNDERGRADUATE -0.478; 95%-0.658 to -0.297). Female undergraduate students (β 11.788; 95%CI 7.161-16.415) had higher DES scores compared with undergraduate male students. In addition, the presence of anxiety symptoms when providing dental care to patients with symptoms or suspected COVID-19 infection was associated with higher DES scores (β 10.460; 95%CI 5.644-15.277) among undergraduate dental students. The level of stress was higher in non-white undergraduate students than white (β 8.912; 95%CI 3.581-14.244). Among both undergraduate and graduate dental students, higher SOC scores were associated with lower DES.
