Objective : Cognitive fusion, or believability, in acceptance and commitment therapy (ACT), refers to the tendency to become entangled in one's thoughts or feelings. It is an important factor in the development and maintenance of anxiety disorders. However, there is a lack of validated self-report measures for cognitive fusion and defusion, particularly for individuals with anxiety. To address this gap, this study aimed to evaluate the Korean Version of Believability of Anxious Feelings and Thoughts Questionnaire (K-BAFT). Methods : A total of 608 university students and 85 patients with obsessive-compulsive disorder (OCD) took part in this study. They were asked to complete various psychological measures, including the K-BAFT, other measures of ACT processes, and symptom scales. The researchers then analyzed the psychometric characteristics of the K-BAFT. Results : The results of the exploratory and confirmatory factor analyses indicated that the three-factor structure of the K-BAFT, which was reported in the original study, was also found in the university sample. Additionally, both the student and the OCD group demonstrated strong internal consistency (α=0.86 and 0.91, respectively). In the university sample, the K-BAFT showed a strong correlation with the Cognitive Fusion Questionnaire (r_s=0.53, p<0.001). However, it had a weak correlation with symptoms scales for depression, anxiety, and stress (all r_s<0.32). Furthermore, the OCD group had higher scores on the K-BAFT compared to the university sample. Conclusion : K-BAFT is considered to be a reliable and valid self-report tool for measuring cognitive fusion with anxious thoughts and feelings.

Objective : Impaired response inhibition has been suggested to play an important role in the pathophysiology of obsessive-compulsive disorder (OCD). The aim of this study was to evaluate the response inhibition in patients with OCD, by using the Go/NoGo paradigm, and to better understand its associations with clinical symptoms. Methods : The participants included 63 OCD patients and 80 healthy volunteers matched in age and sex. response inhibition was evaluated using computerized Go/NoGo task, in which their commission error rates, omission error rates, and mean response times were measured. The severity of clinical symptoms in the OCD patients was assessed using Montgomery-Asberg Depression Scale and Yale-Brown Obsessive Compulsive Scale. Result : OCD patients showed significantly impaired inhibition and higher omission errors rates despite their slower response time, compared to normal controls. Clinical symptoms were not correlated with commission errors and omission errors. Conclusion : The present results indicate that impairment in response inhibition may play a critical role in the pathophysiology of OCD as a trait. These findings suggest that deficit of response inhibition may contribute to developing and maintaining clinical symptoms such as compelling need to repeat certain actions in patients with OCD.

Diagnosing post-traumatic stress disorder (PTSD) is challenging for several reasons: a lack of training in trauma assessment for most clinicians, underreporting and avoidance by patients, the overlapping of symptoms, and a high comorbidity with other mental disorders. Thus, a careful evaluation and differential diagnosis are essential for the treatment and management of this population. A concept of posttraumatic reaction in people with narcissistic vulnerability, called Trauma-Associated Narcissistic Symptoms (TANS) had appeared in the literature; this has not been, however, systemically investigated. This study examines three cases of TANS that developed after traumatic events such as traffic accidents and physical assault. TANS may mimic PTSD and can show similar features; however, a careful attention to the context and meaning of symptoms can help the clinicians in differentiating TANS from PTSD. Clinicians working with trauma and compensation evaluators should be on alert for this easily overlooked condition.

Objective : Mismatch negativity (MMN) provides an electrophysiological index of an involuntary attention switching process. This study investigated MMN anomalies and their relationship to clinical variables in patients with obsessive-compulsive disorder (OCD). Methods : Study participants were 29 OCD patients and 24 normal controls. We used a 128-channel EEG to measure MMN during a passive oddball paradigm. Then we assessed the correlations between MMN amplitudes and clinical measures. Results : The OCD patients exhibited significantly greater MMN amplitude compared to the controls. Also, the right frontal lobe MMN amplitudes correlated significantly to the OCD patients' Yale-Brown Obsessive Compulsive Scale total scores (r=-0.520, p=0.005). Conclusion : These results suggest that MMN anomalies in OCD patients reflect a monitoring circuit dysfunction, raising the possibility that the OCD's pathophysiology includes glutamatergic dysfunction.

Even experienced clinicians have difficulties in diagnosing posttraumatic stress disorder (PTSD) exactly, due to its diverse clinical features, which vary according to individuals, traumas, and various comorbid psychopathologies, and its related compensation issues. It is usually mandatory for clinicians and researchers to use screening and assessment tools when diagnosing and evaluating PTSD. To date, research has developed numerous PTSD screening and assessment tools ; therefore one of the cardinal issues is to select the best of the various tools, the one most suitable for the clinician's or researcher's purposes. This article reviews several currently-available subjective and objective instruments for the diagnosis and evaluation of PTSD and groups them according to whether they are Diagnostic and Statistical Manual for Mental Disorders-Correspondent Measures ; PTSD-Focused, Non-DSM-Correspondent Measures ; or Empirically Derived Measures. We present the instruments' psychometric properties and scoring methods and describe their merits and weak points, focusing on their practical usage.

Most patients with Tourette's disorder experience an uncomfortable sensory phenomenon called the premonitory urge immediately before experiencing tics. It has been suggested that premonitory urges are associated with comorbidities such as obsessive compulsive disorder, anxiety disorders, and attention-deficit/hyperactivity disorder, although these associations have been inconsistent. Most patients experience tics as a result of the premonitory urges, and after the tics occur, most patients report that the premonitory urges are temporarily relieved. As a consequence, several studies have assessed the premonitory urge and its potential therapeutic utility. Based on the concept that the premonitory urge induces tics, behavioral treatments such as Exposure and Response Prevention and Habit Reversal Therapy have been developed. However, it is still unclear whether habituation, the main mechanism of these therapies, is directly related to their effectiveness. Moreover, the observed effects of pharmacological treatments on premonitory urges have been inconsistent.

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.
