Aim:The aim of this study is to investigate the effect of swallowing anxiety on gastroscopy time and sedation type and its relationship with health literacy. Methods: Participants between the ages of 18-75, who were registered in Karacabey Ulubatli Hasan Family Health Center and applied with dyspeptic complaints and underwent gastroscopy, were evaluated in the study. Persons who volunteered to participate in the study were examined through the Sociodemographic Data Form, the State Trait Anxiety Inventory (STAI), the Swallowing Anxiety Scale (SAS), and the Health Literacy Scale (HL-EU-Q16).Results: In the study, it was found that women's STAI and SAS mean scores were higher than men's mean scores (p<0.05). It was found that SAS scores differed significantly according to economic status (p<0.05). It was determined that the rate of patients with undergraduate education was higher in the local anesthesia group (p<0.05). It was found that the endoscopy period was longer in the patient group with psychiatric disease than in the group without psychiatric disease (p<0.05). In the study, it was found that there was a significant positive correlation (r=0.22, p=0.002) between SAS scores and STAI-I scores. It was found that there was a significant positive correlation (r=0.37, p<0.001) between SAS scores and STAI-II scores. According to the STAI-I and STAI-II scales, as a result of the ROC analysis in order to predict the presence of anxiety in the patient and whether this anxiety is continuous; It is predicted that if the total score to be obtained from SAS is >19, the patient may have anxiety, and if the total score is >22, the continuity of this anxiety can be mentioned. In addition, a statistically significant negative correlation was found between the ages of the cases and their HL-EU-Q16 scores (r=-0.14, p=0.05). Conclusions: State and trait anxiety symptoms and swallowing anxiety symptoms are common in patients presenting with dyspeptic complaints. In dyspeptic patients, SAS is an appropriate measurement tool in order to determine swallowing problems of psychological origin. It may be beneficial for their mental health to provide anti-anxiety information before endoscopy to people with a score of 19 or higher on SAS. The fact that health literacy results are not associated with anxiety tests is a valuable finding. It suggests that while making the accurate health decisions, individuals exhibit an anxiety-free behavior.
