Background: This study aims to: (1) examine rates of obesity and physical health complaints among 911 telecommunicators; and (2) document the role of emotion dysregulation, psychological inflexibility, duty-related distress and dissociation, and psychopathology in predicting obesity and physical health complaints in this population. Methods: The sample consisted of 911 telecommunicators from across the country (N = 758). Participants completed an online survey assessing their mental and physical health functioning. Results: A total of 82.5% of the sample reported a body mass index that fell within the overweight or obese category and an average of 17 physical health complaints within the past month. Peritraumatic reactions (distress and dissociation), emotion dysregulation, and psychological inflexibility had effects on physical health largely through psychopathology (alcohol abuse, post-traumatic stress disorder, and depression). Conclusion: Development of adapted prevention and intervention efforts with this population is needed.

Virtual reality (VR) provides an immersive and interactive 3-dimensional system, which allows an individual to become immersed in a computer-generated situation. VR technology has been administered in the exposure-based treatment of a variety of psychiatric disorders, including acrophobia, fear of flight, and post-traumatic stress disorder. Furthermore, VR systems have also been developed for the use of research and treatment in addiction. They might have advantages in cue exposure therapy, by increasing the salience of cues, as well as assessments of cue reactivity in addiction. This article summarizes the application of VR in the field of psychiatry. More importantly, it suggests the possibilities of clinical use of VR technology, in the treatment of addiction.

Background and objective: This study was conducted to investigate the effects of forest therapy programs on reducing post-traumatic stress disorder (PTSD), depression and improving mood states in fire officers. Methods: To determine PTSD, depression, and mood states before and after the forest therapy program, the survey results of 185 fire officers were analyzed. Frequency analysis was conducted to identify the demographic characteristics of the participants, and Wilcoxon signed-rank test to analyze the differences among group. Results: As a result of a comparative analysis of PTSD before and after the program, there was a significant decrease in PTSD from 10.65 ± 12.00 to 5.64 ± 8.29 after the program. Depression also showed a statistically significant difference from 3.21 ± 4.00 to 2.21 ± 3.47 after the program. As a result of comparatively analyzing mood states before and after the program, there was an increase in positive factors and a decrease in negative factors. Total mood disturbance (TMD) also showed a statistically significant decrease from 5.78 ± 17.37 to -7.38 ± 10.35 after the program. Conclusion: This study has significance in verifying that forest therapy programs can bring psychological changes to fire officers, and these results can be used as a basis for stress management and relief of fire officers.

It has been reported that stressful events in early life influence behavior in adulthood and are associated with different psychiatric disorders, such as major depression, post-traumatic stress disorder, bipolar disorder, and anxiety disorder. Maternal separation (MS) is a representative animal model for reproducing childhood stress. It is used as an animal model for depression, and has well-known effects, such as increasing anxiety behavior and causing abnormalities in the hypothalamic-pituitary-adrenal (HPA) axis. This study investigated the effect of MS on anxiety or aggression-like behavior and the number of GABAergic neurons in the hippocampus. Mice were separated from their dams for four hours per day for 19 d from postnatal day two. Elevated plus maze (EPM) test, resident-intruder (RI) test, and counted glutamic acid decarboxylase 67 (GAD67) or parvalbumin (PV) positive cells in the hippocampus were executed using immunohistochemistry. The maternal segregation group exhibited increased anxiety and aggression in the EPM test and the RI test. GAD67-positive neurons were increased in the hippocampal regions we observed: dentate gyrus (DG), CA3, CA1, subiculum, presubiculum, and parasubiculum. PV-positive neurons were increased in the DG, CA3, presubiculum, and parasubiculum. Consistent with behavioral changes, corticosterone was increased in the MS group, suggesting that the behavioral changes induced by MS were expressed through the effect on the HPA axis. Altogether, MS alters anxiety and aggression levels, possibly through alteration of cytoarchitecture and output of the ventral hippocampus that induces the dysfunction of the HPA axis.

Purpose: This study aimed to determine the level of postpartum posttraumatic stress disorder (PTSD) and postpartum depression (PPD) in Korean mothers with healthy babies and to explore the factors related to postpartum PTSD. Methods: This study used a longitudinal survey design to explore the levels and association of PPD and PTSD. Two hundred women were recruited during pregnancy and the data were collected via online survey from 166 mothers (84% retained) who gave birth to healthy babies, at two postpartum periods: Fear of childbirth was assessed at the 1st week; and spousal support, PPD, and postpartum PTSD were surveyed at the 4th week postpartum. Descriptive statistics, t-test, one-way analysis of variance, Chi square test, and multiple regression were done. Results: The mean age of mothers was 33.12 (±3.97) years old. Postpartum PTSD was low (8.95±6.49) with 1.8% (n=3) at risk (≥19). PPD was also low (6.68±5.28) and 30.1% (n=50) were identified at risk (≥10). The comorbid rate of PPD with PTSD was 6%. Mothers who did not have a planned pregnancy had higher scores of PPD (t=-2.78, p=.008), whereas spousal support and PPD had negative relationship (r=-.21, p=.006). The overall explanatory power for postpartum PTSD was 55.2%, of which PPD was the only significant variable (β=. 76, t=13.76, p<.001). Conclusion: While only 1.8% was at risk of postpartum PTSD at 4 weeks postpartum, PPD prevalence was 30.1% and PPD was the only influential factor of postpartum PTSD. Assessment and counseling of PPD are required as well as screening for postpartum PTSD. More research is also needed on postpartum PTSD in Korean women.

Don DeLillo has shown considerable interest in terror, frequently depicting extreme dread of something terrible to happen, in his literary texts. Since more than three thousand innocent people in New York were killed by the 9-11 terrorist attack in 2001, the anticipation about what kind of fiction he would write as a New Yorker was high. DeLillo's novel Falling Man (2007) in fragmentary detail represents the scene of the terrorism from the perspective of Keith Neudecker, a lawyer who escapes the collapsing world trader center. Neudecker's post-traumatic stress disorder in the first chapter is followed by the free-associative portrayal of various impacts of the 9-11 terror on Neudecker's wife Lienne in the second chapter. The random mixture of the first person narratives from such diverse view-point characters as Neudecker's son Justin, relatives and friends, with dialogues and recollections yields a very close picture of the consequences of terrorism. Reading DeLillo's Falling Man in juxtaposition with a Japanese Canadian novel Obasan by Joy Kogawa, reminiscences of the maltreatment of Japanese Canadians during and after the second world war, surfaces the authorial intention of the two novels. They as trauma literature emerge to aim at curing the readers and proposing post-traumatic ethics. Laurie Vickroy's theory of trauma narrative and cure, E. Ann Kaplan's theory of trauma witness narrative and responsibility, and Emmanuel Levinas's theory of trauma memory and ethics offer theoretical grounds for the convincing analysis of the two texts.

Objectives : The aim of this study was to investigate Post Traumatic Stress Disorder (PTSD)-related symptom severity, level of functional impairment and personality profiles between full-blown PTSD, partial PTSD and non-PTSD groups among 59 adolescent survivals from the Incheon fire disaster. Method : Using Short Screening Scale for DSM-IV PTSD, victims of the disaster were assigned to a full-blown PTSD group (n=18), a partial PTSD (n=22), or a non-PTSD group (n=19). Assessments included the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the Impact of Event Scales (IES), the McBride's Degree of General Labor Loss, and the Korean Version of Temperament and Character Inventory (K-TCI). Results : Significantly severe PTSD symptoms (F=4.832, df=2, p<.05) and functional impairment (F=12.144, df=2, p<.01) were demonstrated by PTSD groups as compared to the non-PTSD group. Interestingly, full and partial PTSD did not differ in these comparisons. Similarly, the subtypes of PTSD did not differ with respect to personality profiles using the K-TCI ; however, personality profiles were sharply differentiated between the PTSD and non-PTSD group. Conclusion : Although high subject homogeneity and small sample size may limit the results of this study, the present results highlight the possibility of the underestimation as well as the insufficient, treatment and compensation of partial vs full PTSD.

Objective : The purpose of this study was to establish a school-based mental health intervention. The success of which was indexed by its effects on the social anxiety symptoms of the enrolled adolescents. Methods : This program for promoting mental health among adolescents in the community was adopted by three middle schools that volunteered to participate in the project. The program included screening for emotional problems related to social anxiety, depression, suicide, and post-traumatic stress disorder. Case management was provided for groups considered high-risk for depression, suicide, or post-traumatic stress disorder; cognitive-behavior therapy was provided for those at high-risk of developing social anxiety. Additionally, educational programs for the prevention of suicide, a "loving life" module, and mental health promotional campaigns were also included. In total, 1,100 middle school students completed self-report questionnaires. Twenty-five students in the high-risk group for social anxiety participated in a cognitive-behavior therapy program, comprising eight sessions, and conducted by two clinical psychologists. Results : Following the suicide prevention education program, suicide awareness among students increased and coping strategies were improved. In addition, the loving life program was associated with positive self-perceptions by many students. Furthermore, social anxiety symptoms showed a statistically significant difference after the cognitive-behavior therapy program. After the therapy, not only did social anxiety symptoms improve, depressive symptoms and suicidal ideation decreased significantly, while self-esteem and psychological resilience significantly increased. Conclusion : A school-based mental health intervention was successfully implemented in three middle schools and improved the mental health of the participating students. Therefore, this intervention could be widely implemented to promote positive mental health among middle school students.

한국의 COVID-19 대유행 기간 동안 병원 간호사의 외상 후 스트레스 장애증상(PTSD)에 영향을 미치는 요인을 조사하기 위함이다. 방법: 횡단적, 서술적 연구설계로 병원에서 COVID-19 환자를 다루는 간호사 180명을 대상으로 2020년 12월부터 2021년 1월까지 온라인 설문 조사를 통해 데이터 수집을 하였다. 이 설문조사는 사회인구학적 질문, 외상 후 스트레스 장애 22항목, D유형 성격 14항목, 회복탄력성 25항목, 사회적 지지 23항목이다. 연구결과: 이 표본(n=180)에서 간호사의 56.1%(n=101)가 PTSD 고위험군에 해당하였다. PTSD 고위험군의 경우 회복탄력성과 사회적 지지 정도가 PTSD 저위험군에 비해 낮았으나 두 변수 모두 통계적으로 유의한 차이는 없었다(회복탄력성 t=0.207, p=.836, 사회적 지지 t=1.07, p=.287). PTSD에 영향을 미치는 요인으로는 교육(OR=2.23, p=.041)과 D유형 성격(OR=3.67, p<.001)으로 확인되었다. 결론: 연구의 결과는 COVID-19와 같은 전염병 동안 PTSD에 영향을 미치는 요인을 확인함으로써 간호사의 PTSD를 확인하고, 이를 극복하기 위한 심리 프로그램 등 관리 체계를 적용하기 위해 활용될 수 있다.
