Therefore, this study evaluated the levels of obsession and fear related to COVID-19 in patients with diabetes who were fully vaccinated compared to those with incomplete vaccination. This study employed a causal-comparative design. The statistical population included 362 patients with diabetes including fully vaccinated and in completely vaccinated individuals. These patients were recruited from vaccination centers in Torbat Heydariyeh City using a convenience sampling method. . Research instruments included the Fear of COVID-19 Questionnaire and the COVID-19 Obsession Scale. Data were analyzed using the Chi-square test and the independent two-sample t-test. SPSS version 21 software was used for analysis. A significant difference was observed between the fully vaccinated and incompletely vaccinated groups in terms of COVID-19 obsession and fear of COVID-19 (p < 0.05). According to the observed means, the mean values of COVID-19 obsession and fear of COVID-19 were higher in patients with diabetes with full vaccination compared to the group with incomplete vaccination. To reduce fear and obsession in patients with chronic diseases such as diabetes, health care programs can use psychological programs and the presence of clinical psychologists. This is especially important when designing treatment and care programs, including vaccination strategies against infectious diseases such as the coronavirus.</span></span></span><br> &nbsp;</div> COVID-19 Obsession, Fear of COVID-19, Patients with Diabetes, Full Vaccination, Incomplete Vaccination 59 65 http://jrhms.thums.ac.ir/browse.php?a_code=A-10-33-5&slc_lang=en&sid=1 Abbas Ghodrati 10031947532846002077 10031947532846002077 No School of Nursing and Midwifery, Torbat Heydariyeh University of Medical Sciences, Torbat Heydariyeh, Iran Zahra Yazdansetad 10031947532846002078 10031947532846002078 No Student Research Committee, Shiraz University of Medical Sciences, Shiraz, Iran Naghmeh Saba 10031947532846002079 10031947532846002079 Yes School of Medicine, Torbat Heydariyeh University of Medical Sciences, Torbat Heydariyeh, Iran
