Objective : Heart rate variability (HRV) is known to reflect autonomic nervous system activity. Individuals with posttraumatic stress disorder (PTSD) are reported to have lower HRVs. We attempted to find HRV indices with head up tilt position that reflect the symptoms well in order to evaluate PTSD symptoms. Methods : Sixty-seven patients with PTSD and 72 patients without PTSD were assessed using the PTSD Checklist for DSM-5 (PCL-5), the Beck Depression Inventory, the Beck Anxiety Inventory and the Pittsburgh Sleep Quality Index. HRV was measured in the head-up tilt position. We collected data regarding heart rate (HR), standard deviation of the NN intervals (SDNN), the square root of the mean squared differences of successive NN intervals (RMSSD), log low-frequency (LNLF) and log high-frequency (LNHF). Results : The value of LNHF was different according to presence or absence of PTSD after head-up tilt position. In the findings of the association between PTSD symptoms and HRV indices as based on head-up tilt, LNHF had a significant correlation with the total score of PCL-5. Conclusion : The reduction of the high-frequency component of HRVs in the PTSD group might reflect more PTSD symptoms.

Objective : This study investigated the relationship between the resilience and posttraumatic stress symptoms, as well as comorbid symptoms in firefighters. Methods : We collected 764 firefighters, who worked at six fire department stations in Gangwon-do. We investigated the impact of event scale-revised (IES-R), the life events checklists (LEC), Connor-Davidson resilience scale (CD-RISC), Beck depression inventory (BDI), state trait anxiety inventory (STAI) and alcohol use disorder identification test (AUDIT). Full PTSD groups, partial PTSD groups and non-PTSD groups, which were classified by IES-R scores, were compared in the LEC, CD-RISC, BDI, STAI and AUDIT, ; multiple linear regression analyses were done for independent predictors of variables. Results : Of the 764 firefighters, there were significant differences in LEC (p<0.001), CD-RISC (p<0.001), BDI (p<0.001), and AUDIT (p=0.001) among the full PTSD groups, partial PTSD groups and non-PTSD groups. However, STAI did not show significant difference among three groups. In multiple regression analysis, CD-RISC (${\beta}=-0.168$, p<0.001), LEC (${\beta}=0.211$, p<0.001) and AUDIT (${\beta}=0.115$, p=0.001) were significant predictors for IES-R. Conclusion : The results of the present study suggested that resilience might be a protective factor in PTSD and comorbid symptoms of PTSD.

Purpose: This study aims to examine the levels of posttraumatic stress disorder (PTSD), depression and social stigma among nurses caring for Corona Virus Disease-19 (COVID-19) patients. Methods: 169 nurses caring for COVID-19 patients participated in this study. Data collection was conducted at university hospitals from March 1 to August 31, 2020. Data analysis was performed for descriptive statistics, t-test, ANOVA, and Pearson correlation coefficients using SPSS/WIN 24.0 program. Results: The mean scores of PTSD, depression and social stigma were 25.16±16.80, 17.26±8.63 and 5.83±2.84, respectively. The PTSD scores were significantly different between the department (F=2.89, p=.037). Depressive scores were significantly different between the marital status (t=2.27, p=.024) and the department (F=4.91, p=.003). Social stigma scores were significantly different between age (F=6.49, p=.002), marital status (t=-3.30, p=.008), having or not having children (t=3.82, p=.001), department (F=5.82, p=.001) and clinical experience (F=7.43, p=.001). Positive correlations were found between PTSD and depression (r=.70, p<.001) and social stigma (r=.22, p<.004). Conclusion: Integrated assessment and management are required to address the psychological and emotional problems faced by nurses caring for COVID-19 patients, and active follow-up measures should be considered.

Purpose: This study explored the mediating role of resilience between post-traumatic stress and emotional exhaustion in nurses during the COVID-19 pandemic. Methods: The data were collected from 193 nurses working at a hospital in Daegu from October 16 to 30, 2020, in the middle of the COVID-19 pandemic. Participants conducted self-reported surveys of post-traumatic stress (Impact of Event Scale-Revised Korean version), emotional exhaustion (Maslach Burnout Inventory), and resilience (Korean Resilience Quotient Test). The data were analyzed using descriptive statistics, frequency, t-tests, Mann-Whitney U tests, Kruskal-Wallis tests, Pearson correlation coefficients, and multiple regression. Mediation analysis was performed using the Baron and Kenny method and Sobel test. Results: The mean scores for post-traumatic stress, resilience, and emotional exhaustion were 16.18±16.18, 183.41±18.29, and 32.64±9.66, respectively. A higher level of post-traumatic stress was associated with lower resilience (r=-.20, p=.004) and with higher emotional exhaustion (r=.33, p<.001). A higher level of resilience was associated with lower emotional exhaustion (r=-.35, p<.001). The resilience was confirmed to have a partial mediating effect in the relationship between post-traumatic stress and emotional exhaustion, verified by the Sobel test (Z=2.31, p=.02). Conclusion: Resilience had a partial mediating effect in the relationship between post-traumatic stress and emotional exhaustion. Thus, nurses should develop individual strengths to reduce emotional exhaustion, and managers should also make efforts to increase the nurses' resilience. It is also necessary to develop and apply a program to strengthen nurses' resilience.

Objectives : The aim of this study was to identify the factors affecting ideas of persecution in post-traumatic stress disorder (PTSD) patients who underwent Clinician-Administered PTSD Scale (CAPS) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Methods : We retrospectively reviewed 116 patients who underwent CAPS and MMPI 2 between May 2013 and April 2020 at Veteran Health Service Medical Center. Based on the CAPS score, the patients were divided into the PTSD group (n=63, age: 58.16±17.84) and the trauma exposed without PTSD group (n=53, age: 67.34±12.05). After checking the correlation between Ideas of persecution, CAPS, and MMPI-2 scales, linear regression analysis was performed to identify the risk factors for clinically relevant symptoms. Results : The PTSD group showed significant differences in Schizophrenia, Ideas of persecution, Dysfunctional negative emotions, Aberrant Experiences, Psychoticism, Negative Emotionality/Neuroticism, Anxiety, Depression, and Anger scales compared to the trauma-exposed without PTSD group. When analyzing the correlation between Idea of persecution, CAPS and MMPI-2 scales, there was a strong association with most of the scales in MMPI-2 and Idea of persecution except Disconstraint. Multiple linear regression analysis performed in PTSD group identified that risk factors for Idea of persecution were Dysfunctional negative emotions and Anger scale. Conclusions : The PTSD group had increased idea of persecution compared to the trauma exposed without PTSD group. Dysfunctional negative emotions and anger may be risk factors for idea of persecution in trauma exposed population.

This thesis is a result of a study of the treatment course of post traumatic stress disorder because of the historical incident which is described in the novel, Uncle Suni by Hyun Ki-young. Uncle Suni survived the massacre which happened during the 4.3 Incident in Jeju Island. However, living a buried life, she suffers a historical trauma. To cure her disorder, she had to know the cause of her illness, such as auditory hallucination, mysophobia, etc. The author describes that kinds of patients should be ensured to get help not only in duty of the society but of the country and that historical justice should stand right. Uncle Suni reexperienced the incident when she happened to discover 'the white bones' and 'the lead bullets' while she was working in her 'Ohmpang field'. To cure her illness, she needed to confess her guilt that she had escaped from the massacre, and deep appreciation about the incident, which means she had to testify, and in the course of the testimony, she had to confess her inner feelings. To solve the historical trauma, there should be a recovery of connection between the patient and the society. The course of treatment should go from the patient herself to the realm of the society through which the patient, Uncle Suni can reach the recovery.

Purpose: The study aimed to determine the impact of post-traumatic stress and ways of stress coping on problem drinking in firefighters. Methods: Data were collected from May 11 to June 11, 2015, in fire brigades across South Korea. Participants were 183 male firefighters who used self-report questionnaires containing questions from the Impact of Event Scale-Revised (IES-R), Ways of Coping Checklist (WCC), and Alcohol Use Disorders Identification Test (AUDIT). Data were analyzed using $x^2$ test, t-test, and logistic regression with the SPSS/WIN 21.0 program. Results: The prevalence of PTSD among firefighters was 36.7% and that of problem drinking was 39.3%. Firefighters with single (OR=0.23, 95% CI=0.038~1.321) and married status (OR=0.46, 95% CI=0.069~3.040) were less likely to have problem drinking than those who were divorced or bereavement. Those with invasion symptoms (OR=1.17, 95% CI=1.031~1.327) and hyperarousal symptoms (OR=0.85, 95% CI=0.722~0.989) were more likely to have problem drinking than those with avoidance symptoms. Conclusion: Post-traumatic stress symptom was a major risk factor that increased problem drinking, and married status reduced problem drinking. There is a need to develop post-traumatic stress symptom management program and early education content for symptom management.

Objective : One of the aims of this study was to confirm the relationship in firefighters who have a high risk of developing posttraumatic stress disorder. We also explored the mediation effects of resilience and posttraumatic growth (PTG) on the association between traumatic experiences and posttraumatic stress symptoms. Methods : A total of 677 firefighters were assessed in terms of the intensity of job-related traumatic experiences using the Visual Analogue Scale. They completed the Korean version of the Posttraumatic Growth Inventory (PTGI), the Korean version of the Impact of Event Scale-Revised (IES-R), and the Korean version of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10). Results : The intensity of traumatic experiences was significantly negatively related to the CD-RISC-10 score, but it was positively related to the PTGI and the IES-R scores. The CD-RISC-10 score had a significantly positive correlation with the PTGI score, but it was negatively correlated to the IES-R score. Path analyses revealed that resilience and PTG independently mediated the association between traumatic experiences and posttraumatic stress symptoms. Conclusion : These results suggest that traumatic experiences contribute to posttraumatic stress symptoms and that these impacts may be mediated through resilience and PTG.

Purpose: This study examined degrees of irrational parenthood cognition, post traumatic stress disorder (PTSD), spousal support, and quality of life and investigated factors that influence the quality of life of infertile women. Methods: Research design was a cross sectional correlational survey with a total of 113 female patients receiving treatment for infertility. Data were collected from August 1 to November 30, 2015. The collected data were analyzed using t-test, ANOVA, Pearson's correlation, and multiple regression analysis. Results: The mean score of the quality of life was $59.0{\pm}14.8$. The quality of life was significantly associated with irrational parenthood cognition (r=-.70), post traumatic stress disorder (r=-.65), and spousal support (r=.56). The factors significantly affecting the quality of life in infertile women were irrational parenthood cognition (${\beta}=-.45$), post traumatic stress disorder (${\beta}=-.34$), and spousal support (${\beta}=-.32$). The explained variance by these factors was 70.4%, and the regression model was valid (F=89.81, p<.001). Conclusion: This study may contribute to the development of nursing intervention program to improve the quality of life of infertile women.
