Childhood and adolescent onset-bipolar disorders have higher rate of comorbidity with anxiety disorders as well as attention deficit hyperactivity disorder and conduct disorder. Obsessive compulsive disorder, social phobia, panic disorder, and separational anxiety disorder are common comorbid anxiety disorders with bipolar disorders in child and adolescent. Prospective and reliable data on temporal and causal relationship between the onset of bipolar disorders and the onset of comorbid anxiety disorders are still in debate. The authors report 2 adolescent cases with antidepressant induced-manic episodes with preceding anxiety symptoms. The authors suggest careful prescription of antidepressants for anxiety disorders, even for those who do not have definite past history or family history of bipolar disorders. Further comprehensive and prospective studies are requested for the temporal relationship and pharmacological guideline for comorbid bipolar disorders and anxiety disorder in child and adolescent.

Anxiety is one of the basic human emotions. From the evolutionary psychology point of view, it is a necessary factor for survival and prosperity of human beings that had been developed throughout time with the history of human survival and development. Anxiety plays the role of protecting one from social or physical threats. In reality, lacking of anxiety showed lots of examples of maladjustments. But the result of over-adjustment, which is overanxious disorder, is definitely disturbing one's survival and growth, and it can lead to anxiety disorder that needs to be treated. Anxiety from the evolutionary psychology point of view, started as a primary adjustment form and it evolves into various types of anxiety disorders that relates to the modern society's characters. Therefore, having the grasp of evolutionary psychology, which can be the base of treating anxiety and anxiety disorders, is very important. So from now on, studies for this aspect would need to be done as integrated and multidisciplinary studies not only by psychiatrists, but by including epidemiologists, psychologists, ecologists, biologists, and neuropsychologists. In this article, the author tried to review and explore the idea of anxiety and anxiety disorders from the evolutionary psychology point of view.

Objective : Brief screening for anxiety symptoms in clinical practice can further facilitate the diagnosis and evaluation of anxiety disorders. This study examined the factorial validity of the Korean version of the State-Trait Inventory (STAI)-Form X, one of the most frequently used self-report questionnaires for anxiety. Methods : Data from the STAI and Beck Depression Inventory were obtained from a consecutive sample of 200 outpatients diagnosed with DSM-IV anxiety disorders at a psychiatric unit of a university hospital. The factor structures of the State and Trait Scales were assessed using exploratory factor analysis. Results : Three-factor components, including 'State anxiety present', 'State anxiety absent' and 'Selfconfidence', were extracted from the State Scale, explaining 59% of the total variance. A four-factor solution involving 'Trait anxiety and depression present', 'Trait anxiety and depression absent', 'Anxiety proneness' and 'Stability' (59% of total variance) was extracted from the Trait Scale. The internal consistency of the STAI and factors were satisfactory. There were significant correlations between depressive symptoms and factors of the STAI. Conclusion : The STAI-form X showed factorial validity for Korean patients with anxiety disorders. However, our finding that this anxiety scale also measures depressive symptoms should be interpreted with caution.

Major depressive disorder causes significant dysfunction and disability. Many of depressed patients tend to have cormobid anxiety disorders, substance use disorders and personality disorders, and so on. In this study, we reviewed researches about the effects of comorbid anxiety disorder, substance use disorder on depressive symptoms, progress, treatment, etc. In addition, the latest knowledges related to treatment was reviewed. If the symptoms of anxiety disorder coexist, They leads to the deterioration of the course and has an adverse effect on treatment response. Comorbid substance use disorder, such as alcohol dependence, causes worsening of symptoms and progression, and a loss of therapeutic response. Therapeutic clinical guidelines and instructions to comorbid psychiatric disorders on major depressive disorder was not established clearly, but consensus-based or evidence-based studies will be necessary for treatment for comorbid psychiatric disorders on major depressive disorder.

Objectives: The purpose of this study is to investigate the composition, origins, and utilization of Jiuwei Zhenxin Granules for anxiety disorders in Chinese medicine. Methods: Studies found in six databases were chosen, and major indicators were analyzed. Results: Jiuwei Zhenxin Granules are modified from Pyeonbojinsimdan on Taepyeonghyeminhwajegukbang. In Jiuwei Zhenxin Granule studies, there were significant effects in nine outcomes in twenty-four studies of primary anxiety disorders and seventeen outcomes were similar in effect to that in the control. Three outcomes in ten studies of secondary anxiety disorders showed significant effects, and five outcomes were similar in effect to that in the control. Conclusions: Jiuwei Zhenxin Granules is a prescription that focuses on harmony of vital energy (qi) and blood, and stability of mind. The significance of the constitution of Jiuwei Zhenxin Granules is similar to that of domestic anxiety disorder studies, so it seems to be applicable to anxiety disorders. With regard to domestic use of Jiuwei Zhenxin Granules, more research is needed on the dosage according to the formulation.

Objective : To obtain the incidence rate of anxiety disorders among the active duty Korean military personnel, who visited the military hospitals from 2011 to 2013, this descriptive epidemiological study was performed. Methods : After acquiring the data for the anxiety disorders from Defense Medical Statistics Information System, the annual incidence rates were analyzed by forces, position status, and specific disease entities. Results : One thousand, nine hundred and thirteen (1,913) active duty male military personnel were diagnosed with any kinds of anxiety disorders in their first visit to the psychiatric outpatient department (OPD). The total OPD visit counts were 7,870 during the same period. Anxiety disorder, NOS was the most frequent disorder, followed by panic disorder. While the incidence rate for anxiety disorder, NOS decreased, panic disorder displayed increasing tendency. Stress-related disorders and obsessive-compulsive disorder were positioned third and fourth, respectively, for the number of first visit and they both showed decreasing tendency in annual incidence rates. Social anxiety disorder, specific phobias, generalized anxiety disorder (GAD) and mixed anxiety-depressive disorder followed next. The annual incidence rates for anxiety disorders showed decreasing tendency, particularly evident in army soldiers. However, naval officers showed higher anxiety disorder incidence rate compared to those of the army and the air forces. Conclusion : Comparing to general population, panic disorder was higher while specific phobias and GAD were lower in the Korean military. It is interesting to observe higher incidence rate for anxiety disorder in naval officers and warrants further evaluation.

Objective : Depressive symptoms often coexist with other anxiety disorder symptoms. Furthermore, an anxiety disorder that is comorbid with a depressive disorder results in more severe symptoms and a poorer outcome prognosis. To understand the construct of depressive symptoms in anxiety disorder, this study investigated the factor structure of the Beck Depression Inventory among outpatients with anxiety disorders. Methods : All data were from psychiatric department outpatients at a university-affiliated hospital. We conducted a principal component analysis using data from 194 outpatients with DSM-IV anxiety disorders and calculated goodness-of-fit-indices. Results : Exploratory factor analysis revealed a four factor structure--Cognitive-affective symptoms (Factor 1), Somatic symptoms (Factor 2), Self-reproach (Factor 3), and Hypochondriasis/indecisiveness (Factor 4)--and a 57% total variance. This four-factor model demonstrated an acceptable level of model fit, and it fit better than did a three-factor solution from the literature on depressive disorder. Conclusion : This study's results suggest a difference in the construct of self-reported depressive symptoms in anxiety disorders. These findings also support a dimensional approach to studying anxiety and depression. Further studies may benefit from including comorbid depressive disorder and its influence on anxiety disorders.

Objectives: Many fields have changed since covid-19, psychotherapy being no exception. With the pandemic associated increase in untact treatment, interest in virtual reality exposure therapy has also increased. The aim of study was to analyze recent literature using virtual reality therapy for the treatment of anxiety disorders. Methods: We searched five databases from dates between October 1 to November 1, 2020. We selected articles related to the treatment of anxiety disorders using virtual reality therapy and analyzed the trend of that, not thesis but domestic articles. Results: There were 6 RCT studies and 3 were case reports where, based on the DSM-4, the participants presented with anxiety disorders including 2 with presentation anxiety, 1 heterosexual anxiety, 1 test anxiety, 1 social anxiety, 1 dental anxiety, 2 Acrophobia, and 1 social phobia. Treatment sessions varied from 1 session to 18 sessions, but 5 studies conducted 4 sessions, and all studies attempted virtual reality exposure for 30-minute time periods. 8 studies used HMD as the VR device and 1 study did not report a device. Conclusions: Anxiety disorders treated using virtual reality included speech anxiety and acrophobia. Median treatment session number was 4 and sessions were less than 30 minutes. The most common VR device used was an HMD. VR psychotherapy showed limitations relating to patient experience including cyber sickness and a lack of immersion. In addition, most of the studies were conducted with patients who visited hospitals utilizing Western medical practices. Currently, virtual reality therapy (VRT) intervention in oriental medicine is lacking. The lack of research in this area suggests analyzing data from VR psychotherapy in oriental medicine could provide novel and useful information.
