OBJECTIVES: Body image distortion is found in eating disorder and obesity and there are some evidence that schizophrenia is associated with body image distortion. This study sought to find whether schizophrenic patients report more body image distortion than healthy individuals and whether it is related with symptomatology. METHODS: A total of 88 inpatients with schizophrenia and 88 healthy controls were recruited. Weight, height, and body image accuracy were assessed in all participants, and assessment of mood, psychotic symptom severity and self-esteem, and personal and social performance scale were conducted. RESULTS: The patients with schizophrenia had higher Body Mass Index (p < 0. 001) and underestimated their body size more than controls (26.14% vs. 5.13%, p < 0.001). Multiple regression analysis showed that lower depressive symptoms and higher scores of general psychopathology predicted underestimation of body size. CONCLUSION: Weight gain and metabolic syndrome are common adverse events of pharmacological treatment of schizophrenia. Thus, underestimation of body size among patients with schizophrenia may interfere with effort to lose weight or seek weight reduction programs. Clinicians need to consider possible unterestimation of underestimation of body size in patients whose general symptomatology is severe.

Objectives: ：The purpose of this study was to examine whether the MMPI-2-RF serves as a useful tool to differentiate between the subtypes of high risk of suicide among psychiatric outpatients. Methods: ：Patients were recruited from the department of psychiatry of university hospital. Participants were diagnosed using DSM-5 criteria by board certified psychiatrists. Their medical records were reviewed retrospectively. And participants were put into 4 groups (Suicide ideation, Suicide attempt, Non-suicidal self-injury, and general psychiatric diagnosis as a control group). For statistical comparison, the MANCOVA with gender as a covariate was used. Results: ：The results indicated that as previous research with non-clinical sample suggested, psychiatric outpatients with high suicide risk also have significantly higher Emotional/Internalizing Dysfunction, Helplessness/ Hopelessness, Suicidal/Death Ideation, Demoralization, Cognitive complaints, Cynicism, Dysfunctional negative thoughts than general psychiatric patients group. But group differences within the high suicide risk patients have not been observed. However, suicide attempt group and NSSI group has higher Behavioral/Externalizing Dysfunction, RC4, AGG than general psychiatric patients group. But there was no difference between suicidal idea group and general psychiatric patients group. Conclusions ：There was no group difference observed between all three subtypes, which mean the MMPI- 2-RF may not be the useful diagnostic tool to navigate high suicide risk subtypes. Even though there was no difference observed in the suicide ideation group, suicide attempt group and NSSI group have higher aggression and externalization. So those indexes could serve as a useful marker to investigate riskiness of suicide related symptoms.

Objectives: ：This study investigate to identify the stability of temperament and personality characteristics of patients including Posttraumatic Stress Disorder (PTSD) patients. Methods: ：The number of subjects was 102, of which 33 were PTSD patients and 69 were non-PTSD patients. To demonstrate the change in individual temperament and personality characteristics, Temperament and Character Inventory (TCI) were administered repeatedly on the subjects. Repeated measures ANOVA and simple main effects analysis were conducted. Results: ：When analysed by dividing the subjects into PTSD groups and non-PTSD groups, the differences between the primary and secondary tests did not appear in the non-PTSD groups, but the differences between the primary and secondary tests were significant in Harm Avoidance (HA), Reward Dependence (RD), Self-Directedness (SD), Cooperativeness (C). In addition, it was noted that the time and group interaction effects of HA, RD, SD and C were significant, and that the main effects of time of HA, RD, SD and C were significant. Conclusions ：This study is meaningful in that in the course of experience and recovery of traumatic events,we have clinically confirmed that changes in the temperament, known as stable variables, are possible.

Objectives: ：This study aimed to examine the mediating effect of sleep quality and interpretation bias for ambiguity in the relationship between hopelessness and suicidal ideation in psychiatric patients. Methods: ：A total of 231 psychiatric outpatients and inpatients completed the Beck Hopelessness Scale, Pittsburgh Sleep Quality Index, Ambiguous/Unambiguous Situations Diary-Extended Version, and Ultra-Short Suicidal Ideation Scale. Data analysis was conducted using regression analyses and bootstrap sampling. Results: ：The results of this study showed that hopelessness had a direct effect on suicidal ideation, and that sleep quality and interpretation bias for ambiguity mediated the association between hopelessness and suicidal ideation. Moreover, there was a significant double mediating effect of sleep quality and interpretation bias for am-biguity on the relationship between hopelessness and suicidal ideation. Conclusions ：These results suggest that it is important to consider both sleep quality and interpretation bias for ambiguity to prevent hopelessness from leading to suicidal idea. These results suggest that considering both sleep quality and interpretation bias for ambiguity may be important in preventing hopelessness from leading to suicidal ideation.

OBJECTIVES: Dissociative Experiences Scale (DES) is the most widely used and studied instrument for measuring dissociative symptoms with its favorable psychometric properties well described in the literature. However, recent debate on factor structure and multidimensionality has brought attention to factorial validity of the scale. This study tested the factor structure of a Korean translation of the scale (KDES-II) with confirmatory factor analysis in a clinical population. METHODS: Exploratory principal component analysis were conducted with data from 340 psychiatric patients and confirmatory factor analysis (maximum likelihood estimation) with 262 psychiatric outpatients. RESULTS: Exploratory analysis revealed four factor structure of the scale with total variance of 55.9% : Depersonalization/derealization (Factor 1), Amnestic dissociation (Factor 2), Absorption (Factor 3), and Pseudopsychotic symptoms (Factor 4). However, original three- and one- factor model were also acceptable considering the goodness-of-fit indices. CONCLUSION: Despite heterogeneity of the sample, KDES-II showed factorial validity and supported a cross cultural stability of DES. We suggest use of original three factor solution for Korean clinical population.

This article reviews existing Eye Movement Desensitization and Reprocessing (EMDR) literature concerning its effectiveness, theory, mechanism, and procedural aspects in the treatment of post-traumatic stress disorder (PTSD). Evidence from randomized clinical trials and meta-analyses indicates that EMDR is as effective as well established treatments such as exposure and cognitive behavior therapy. And moreover, EMDR may be more efficient in terms of unnecessary homework assignment and fewer treatment sessions. The current status of EMDR occupies one of legitimate and standard psychotherapeutic approaches in adult PTSD treatment. Mechanism for treatment efficacy is poorly understood at present and putative at most, however, there is a growing body of literature on neurobiological change after successful EMDR treatment.

Pilot fatigue is a great hazard to aviation safety. In recent years, longdistancefights have been increasing and flight hours have been increasing, whichhas made fatigue issues important. International organizations in the aviation sectors(ICAO, FAA, IATA etc.) recommend management of fatigue within the SMS (SafetyManagement System) framework. A scientific and systematic approach to measuringfatigue is required as a prerequisite to preparing safety management measures forpilot’s fatigue. Therefore, in this study, I would like to consider recent trends andimplications for fatigue measurement. First, I aimed to consider recent the accidentcases related to fatigue. Second, I also considered how to measure the pilot’sfatigue. Finally, the direction of the countermeasures against fatigue through fatigue measurement was developed and suggested.

BACKGROUND: To further understand the relationship between anxiety and depression, this study examined the factor structure of the combined items from two validated measures for anxiety and depression. METHODS: The participants were 406 patients with mixed psychiatric diagnoses including anxiety and depressive disorders from a psychiatric outpatient unit at a university-affiliated medical center. Responses of the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI)-II, and Symptom Checklist-90-Revised (SCL-90-R) were analyzed. We conducted an exploratory factor analysis of 42 items from the BAI and BDI-II. Correlational analyses were performed between subscale scores of the SCL-90-R and factors derived from the factor analysis. Scores of individual items of the BAI and BDI-II were also compared between groups of anxiety disorder (n = 185) and depressive disorder (n = 123). RESULTS: Exploratory factor analysis revealed the following five factors explaining 56.2% of the total variance: somatic anxiety (factor 1), cognitive depression (factor 2), somatic depression (factor 3), subjective anxiety (factor 4), and autonomic anxiety (factor 5). The depression group had significantly higher scores for 12 items on the BDI while the anxiety group demonstrated higher scores for six items on the BAI. CONCLUSION: Our results suggest that anxiety and depressive symptoms as measured by the BAI and BDI-II can be empirically differentiated and that particularly items of the cognitive domain in depression and those of physical domain in anxiety are noteworthy.
