Research on obsessive-compulsive disorder (OCD) has advanced substantially since the DSM-IV was published in 1994. It is time to reexamine the nosology of this disorder, reviewing conflicting views regarding the classification as well as subtypes and specifiers of OCD. Although there is ongoing debate, OCD experts have suggested that OCD be retained in the section related to anxiety disorders and also that along with OCD, this section include obsessive-compulsive spectrum disorders (OCSD), a group of disorders closely related to OCD. A combined 'anxiety and obsessive-compulsive spectrum chapter' has also been proposed to include OCSDs. A growing body of scientific data has provided empirical support for the inclusion of a 'tic-related' subtype of OCD in the DSM-V. However, it remains controversial as to whether to introduce OCD symptom dimensions as specifiers as well as items in the diagnostic criteria. With regard to compulsive hoarding, there has been sufficient evidence to recommend that it be classified in the DSM-V as a separate disorder. Much work remains in order to ensure that the DSM-V is as evidence based as possible. It is necessary to strive toward integrating the biological and psychological data related to OCD and OCSD based on their endophenotypic features.

Background: This study was performed to review the research trends in the treatment of obsessivecompulsive disorder with Morita therapy in China. Methods: We searched articles in the China National Knowledge Infrastructure (CNKI) regarding Morita therapy and "obsessive-compulsive disorder" in medicine and the public health field. And 23 studies were selected and classified. Five before-after comparison studies and 18 randomized controlled trials were performed in patients with obsessive-compulsive disorder in China. Results: Morita therapy and western medicine were used for the treatment of obsessive-compulsive disorder. Most of the studies reported that groups treated with Morita therapy as well as western medicine showed much positive results than those groups treated with western medicine alone. Conclusions: According to this study, Morita therapy for obsessive-compulsive disorder would be an effective and safe intervention. Further clinical studies on the use of Morita therapy in the treatment of obsessive-compulsive disorder should be done in Korea in the near future.

Objectives : This study was performed to review the research trends in treatment for Obsessive-Compulsive Disorder (O.C.D) in traditional Chinese medicine. Methods : We searched articles in CNKI(China National Knowledge Infrastructure) from 1995 to 2012 with key words, "强迫症", "强迫性神经症", "强迫神经", and "强迫性恐惧", and we selected 14 studies except for non-clinical, unrelated or insufficient number of case studies. Then we performed a systematic review of them. Results : 14 studies were divided into 8 case reports and 6 control studies. Most of the studies reported that one or more of Herbal medicine, Psychotherapy, Electroacupuncture therapy, Acupoint stimulating control, and acupuncture treatment of Obsessive-Compulsive Disorder were very effective. However, the quality of these clinical studies was not high. Conclusions : It seems that the researches for obsessive-compulsive disorder have been performed actively in traditional Chinese medicine. We hope that our study can activate clinical research for this disorder in Korean traditional medicine.

The quantitative EEGs of obsessive-compulsive disorder patients were analyzed using spectral analysis and compared to age and sex-matched controls. The subjects were 19 patients(men=15, women=4) suffering from obsessive-compulsive disorder(DSM-III-R). Absolute power, relative power and interhemispheric asymmetry of EEG were used to compare obsessive-compulsive disorder patients with controls. In order to fit the EEG data to a normal distribution, a log transformation of power values of every bandwidth in each deviation was calculated prior statistical analysis. The Wilcoxon rank test was performed to compare obsessive-compulsive group to the control group. In obsessive-compulsive disorder, abnormalities of quantitative EEGs are prominent in fronto-central. These results ore compatible with other brain imaging studies of obsessive-compulsive disorder and suggested that fronto-central area plays an important role in the pathophysiology of obsessive-compulsive disorder.

Objective : The 18-item Obsessive-Compulsive Inventory-Revised (OCI-R) is widely employed to assess symptoms of obsessive-compulsive disorder (OCD). However, this instrument's factor structure does not align with contemporary dimensional models of OCD. Therefore, the objective of this study was to examine psychometric properties of the 12-item Korean OCI (OCI-12) on four obsessive-compulsive symptom dimensions, in patients with OCD. Methods : A total of 157 patients with OCD and 51 healthy controls completed psychological measures, including the OCI-R, Dimensional Obsessive-Compulsive Scale (DOCS), and scales evaluating anxiety and depressive symptoms. Pychometric characteristics of the OCI-12 with three neutralizing and three hoarding items eliminated from the OCI-R, were analyzed. Results : All OCI-12 items registered excellent internal consistency at 0.83. Confirmatory factor analysis revealed strong association between individual items and their proposed latent factors (i.e., subscales). Convergent validity was appropriate. A high correlation was particularly observed for the DOCS score (r=0.71, p<0 .001). Moreover, the OCI-12 was as sensitive as the OCI-R for determining effects of empirically supported treatment for OCD. Conclusion : The OCI-12 is a 12-item measure that adheres to the prevailing 4-factor model of OCD dimensions. Like OCI-R, it possesses good to excellent psychometric properties, including reliability, validity, and sensitivity to treatment.

Obsessive-compulsive disorder (OCD) affects approximately 2-3% of the adult population. OCD is associated with impairments in social and occupational functioning. Although there are effective treatments for OCD, many individuals who suffer from OCD go undiagnosed and untreated. Thus, improvements in the assessment and diagnosis of OCD are needed. This paper provides a review of the instruments used to assess and diagnose patients with OCD. We reviewed clinician-administered inventories and self-report questionnaires. The characteristics, strengths, weaknesses, reliability and validity of each instrument are discussed. We also reviewed the psychometric properties of the Korean version of each instrument.

Objective : The aim of this study is to evaluate the five-factor model of personality in patients with obsessive-compulsive disorder (OCD) related to obsessive-compulsive symptom severity and the distinct symptom subgroups. Methods : We recruited 95 patients with OCD and 116 normal controls in the study. We used the short version of Revised NEO Personality Inventory and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) for the assessment. Results : Patients with OCD showed significantly higher scores in neuroticism than normal controls. On multiple linear regression analysis, we found that agreeableness and conscientiousness were associated with the total Y-BOCS scores. On subscale analysis, agreeableness and neuroticism were associated with the obsession subscale scores and only conscientiousness was associated with the compulsion subscale scores. Furthermore, we found that patients who have contamination/cleaning or symmetry/ordering/counting/arranging as a main symptom presentation had significantly higher mean scores in conscientiousness than patients who have harm due to injury/violence/aggression as a main symptom presentation. Conclusion : In this study, we found that specific personality factors are associated with the obsessive-compulsive symptom severity. In addition, this is the first study to investigate the relationship between the personality factors in the five-factor model and the distinct symptom subgroups in OCD.

Researchers consider obsessive-compulsive disorder (OCD) to be an anxiety disorder, but it often shows comorbidity with other disorders in the affective spectrum. Epidemiological and clinical studies have shown a strong association between OCD and mood disorders. In addition, some reports show the patients with OCD have attentional-processing impairments regarding emotional information. However, research has not revealed the exact nature and degree to which OCD constitutes an affective problem. In this review, we discuss the affective aspects of OCD and the relationship between OCD and mood disorders.

Objectives: The objective of this study is to analyze the Clinical reports of treatment of obsessive compulsive disorder (OCD) in traditional Chinese medicine (TCM). Methods: Clinical reports on obsessive compulsive disorder treatment from 2001 to 2017 were searched using the following key words in the China National Knowledge Infrastructure (CNKI). 'OCD', 'qiangpo zheng'. Results: A total of 22 papers were selected, 12 of which were clinical research papers and 10 case report papers. The acupuncture and moxa treatment was more effective in relieving the clinical symptoms of OCD patients as compared to only using western medicine, and it was also possible to reduce the adverse effects of western medicine. Conclusions: It was established that Traditional Chinese medicine has some effect on the treatment of OCD, but there were limitations as follows. The selected papers were retrieved from only one site of CKNI and did not follow a systematic review methodology. Therefore generalized results could not be derived, further studies should therefore be carried out.
