Generalized anxiety disorder (GAD) is a common but serious form of anxiety disorder. Despite this, the rate of GAD recognition in primary care remains low in both Western and Eastern countries. The GAD-7 and GAD-2 were developed to efficiently identify people with GAD, and their reliability and validity have been well-documented in Western countries. The GAD-7 and GAD-2 have also been widely utilized to screen for other anxiety disorders; however, their diagnostic utility has not been fully just

Cognition is an important factor that affects daily functioning and quality of life. Impairment in cognitive function is a common symptom present in various psychological disorders, which hinders patients from functioning normally. Given that cognitive impairment has devastating effects, enhancing this in patients should lead to improvements in compromised quality of life and functioning, including vocational functioning. Over the past 50 years, several attempts have been made to improve impaire

Cholinergic medications produced marginal improvement in verbal learning and memory and moderate improvements on spatial learning and memory, although there was no evidence to support the use of glutamatergic or serotonergic medications as a stand-alone treatment for improving cognitive function. Cholinergic and glutamatergic agents improved negative and general symptoms, whereas serotenergic medications improved positive symptoms.

Despite the prominent use of the Beck Anxiety Inventory (BAI) in primary healthcare systems, few studies have confirmed its diagnostic utility and psychometric properties in non-Western countries. This study aims to clarify the clinical utility of the BAI as a screening tool for anxiety disorders according to DSM-IV criteria, based on blind recruitment and diagnostic interviews of both clinical and non-clinical participants in the Korean population. A total of 1,157 participants were involved in

SCT benefits people with schizophrenia on a variety of social-cognitive outcomes. Differences in baseline symptoms, gender distribution, antipsychotic medication dose, IQ, and other sample features did not create barriers to treatment benefits. Future studies should aim to enhance the generalization of training effects on broader clinical outcomes.

Acknowledging separable factors underlying negative symptoms may lead to better understanding and treatment of negative symptoms in individuals with schizophrenia. The current study aimed to test whether the negative symptoms factor (NSF) of the Positive and Negative Syndrome Scale (PANSS) would be better represented by expressive and experiential deficit factors, rather than by a single factor model, using confirmatory factor analysis (CFA). Two hundred and twenty individuals with schizophrenia

COVID-19의 장기화가 정신 건강에 미치는 영향을 연구하기 위해, 본 연구는 2020년 5월 8일부터 13일까지 1,000명의 국내 참가자들을 대상으로 외상성 고통, 예방 행동, 우울, 불안, 자살 위험성 등을 조사하였다. COVID-19의 전후의 심리적 영향을 비교하기 위해 COVID-19 이전 기간(2017년 10월부터 2018년 3월까지) 동안 수집된 257명의 국내 참가자 자료를 활용하였다. 추가적으로 COVID-19 상황에서 실직이나 가계수입 감소와 같은 경제적 위험 요인 및 일상 활동의 유지와 같은 심리적 보호 요인들을 탐색하였다. 27.3%의 참가자들이 경도 수준 이상의 외상성 고통을, 34.2%의 참가자들이 경도 수준 이상의 우울 증상을, 28.8%의 참가자들이 경도 수준 이상의 불안 증상을 COVID- 19기간 동안 나타냈으며, 23.6%의 참가자들이 자살 위험 집단으로 분류되었다. 여성과 20대가 남성 및 다른 연령대의 참가자에 비해 높은 우울, 불안 자살 경향

Few psychosocial approaches address the negative symptoms of schizophrenia, which shares common features with depression and anxiety. Behavioral activation (BA) is effective for addressing depression and anxiety in adults with various mental disorders. Motivational interviewing (MI) has been successfully applied to address ambivalence or lack of motivation toward treatment. Motivational and behavioral activation (mBA) has been developed by incorporating the core principles from BA and MI with re

As the aging population increases rapidly throughout the world, various approaches and studies are in progress to prevent age-related diseases. Among the diseases related to the elderly, dementia (in which cognitive function declines) is classified as a mental disorder. Since there is currently no therapeutic agent for dementia, early diagnosis and prophylactic approaches may be useful. In this study, a mobile-based augmented reality system for regular cognitive function training is proposed to

Studies that have specifically examined the effects of motivation on work have been limited to evaluations of baseline motivation and have not accounted for cognition. These have also not examined whether motivation changes over time. In the current analyses, we examined how baseline motivation and longitudinal changes in motivation, along with the effects of baseline cognition, related to work function in a sample of 123 individuals with schizophrenia or schizoaffective disorder participating i
