Objective: The devastating Kahramanmaras earthquake doublet struck with a magnitude of Mw 7.8 and Mw 7.7, occurring 9 hours apart on February 6, 2023. Earthquakes can cause significant psychological impacts. This study aimed to investigate the prevalence and determinants of probable post-traumatic stress disorder (PTSD) among university students eight months following the 2023 earthquake doublet in Kahramanmaras, Turkiye. Method: Convenience sampling was used to recruit participants. The study included 445 university students who completed a detailed questionnaire about the 2023 Turkiye-Syria earthquakes, along with the PTSD checklist for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5, PCL-5). Researchers prepared the questionnaire to evaluate pre- earthquake psychiatric history, behavioral reactions during and after the earthquake, experiences of being trapped under rubble, physical injury status, extent of property damage, and loss of loved ones through face- to-face interviews. Results: According to the PCL-5 scores, 61.6% of the participants exhibited probable earthquake-related PTSD. Factors associated with a higher prevalence of probable earthquake-related PTSD included being female, having severe house damage, pre-existing psychiatric conditions, and a history of traumatic events. Only 26.5% of the participants were in a safer location outside buildings during the second earthquake. Conclusion: A total of 274 subjects (61.6%) were diagnosed with probable earthquake-related PTSD eight months after the 2023 Kahramanmaras earthquake. The determinants linked to a probable PTSD diagnosis were severe house damage, preexisting psychiatric conditions, a history of traumatic events, and being female. These findings enhance our understanding of probable earthquake-related PTSD, its associated risk factors, and underscore the importance of taking preventive measures to mitigate the psychological impacts of earthquakes. Keywords: Earthquake, post-traumatic stress disorder (PTSD), risk factors, disaster

Background Many variables may affect approaches of psychiatrists to methamphetamine-associated psychotic disorder (MAP) treatment. This study was aimed to reach adult psychiatrists actively practicing in Turkey through an internet-based survey and to determine their practices and attitudes to MAP treatment. Methods In this internet-based study, participants were divided into three groups based on their answers: Those who do not follow-up any MAP patient were group 1 ( n  = 78), partially involved in the treatment process of at least one patient diagnosed with MAP were group 2 ( n  = 128), completely involved in the treatment process of at least one patient diagnosed with MAP were group 3 ( n  = 202). Results Psychotropic preferences in insomnia ( p  < 0.001), typical oral antipsychotic choice ( p  < 0.001), preferred doses of olanzapine/risperidone/aripiprazole/amisulpride for maintenance treatment ( p  < 0.001), long-acting injectable antipsychotic use practices ( p  < 0.001), non-antipsychotic psychotropic use characteristics ( p  < 0.001), extrapyramidal system side effect experiences ( p  < 0.001), delirium and life-threatening situations encounter rates ( p  < 0.001) were significantly different between group 2 and group 3. While the duration of maintenance with antipsychotics in the first MAP episode was similar between group 2 and group 3 ( p  = 0.254), it was different in the second and subsequent MAP episodes ( p  < 0.05). A binary logistic regression model containing the experiences of long-acting injectable antipsychotic use, extrapyramidal system side effect, and delirium was created (overall p  < 0.001, Nagelkerke R 2  = 0.435; Hosmer and Lemeshow test p  = 0.203). Conclusions This first study in the field, which examines the current issue in detail, reveals that there are many factors that seriously affect psychiatrists' approaches to MAP treatment in Turkey. Trial registration This study was approved by the Ethics Committee of the Fırat University (Date: 14/09/2023; Number: 2023/12–12).
