Article Synopsis
- The study examines the relationship between alcohol use disorders (AUDs) and comorbid mood and anxiety disorders in Korea, highlighting that many individuals face both issues simultaneously but with under-researched temporal aspects.
- Findings reveal that certain mood and anxiety disorders, such as dysthymic disorder and specific phobias, often precede alcohol dependence, indicating a potential causal relationship.
- The research suggests that understanding the timeline and interactions between these disorders is crucial for effective treatment and management strategies in affected individuals.

Objective: Several previous studies have reported the negative psychological impact of the coronavirus disease (COVID-19) pandemic on medical students worldwide. This study investigated the sociodemographic and psychosocial factors associated with COVID-19-related post-traumatic stress disorder (PTSD) risk among medical students in Daegu, a region that experienced a high concentration of infections.
Methods: A total of 270 students completed the self-reported questionnaires including COVID-19 exposure, psychological measurement, and sociodemographic factors.
Background: With the aging of the population, the number of people with age-related memory complaints has also increased. The purpose of this study was to develop a cognitive rehabilitation program based on mnemonic skills and memory compensatory strategies (CRM) and to investigate the effects of CRM in community-dwelling older adults without dementia.
Methods: This study was an open-label, single-arm, pilot study.
Objective: This study aims to investigate the prevalence of the addictive use of the internet, smartphone, and alcohol in medical students, the association of this addictive use with stress, and the mediating roles of resilience and self-esteem in this association.
Methods: A total of 866 medical students completed measures of three addictive uses as well as psychological scales for stress, resilience, and self-esteem. Correlation analyses and parallel mediation analysis were carried out.
Background: The number of digital game users is increasing, and so is attention to digital gaming's effects on mental health. We aimed to reveal if risky (game addiction) and usual game use (non-risky) are associated with mental health in early adulthood.
Methods: Using data from the nationwide cross-sectional Korean Epidemic Catchment Area study for psychiatric disorders, 415 participants aged 18-30 years were divided into "non-game," "usual game," and "risky game" user groups based on the previous month's game use and cut-off value of game overuse screening questionnaire.
Background: This study investigated trends in the prevalence of major depressive disorder (MDD) by sociodemographic factors in South Korea.
Methods: National samples of the general population aged 18 years or older collected from the nationwide Korean Epidemiologic Catchment Area surveys conducted in 2001 (n = 6,206), 2006 (n = 6,466), and 2011 (n = 5,986) were used. For MDD diagnosis, we conducted face-to-face interviews using the Korean version of the Composite International Diagnostic Interview.
Background: In many high-income Western countries, the prevalence of dementia had been reduced over the past decades.
Objective: We investigated whether the prevalence of all-cause dementia, Alzheimer's disease, vascular dementia, and mild cognitive impairment (MCI) had changed in Korea from 2008 to 2017.
Methods: Nationwide Survey on Dementia Epidemiology of Korea (NaSDEK) in 2008 and 2017 was conducted on representative elderly populations that were randomly sampled across South Korea.
Aim: The aim of this study was to investigate the association between subjective memory complaint (SMC) and executive function in a community sample of South Korean elderly.
Method: Data for 1442 non-cognitive impaired elderly individuals aged 65 and over were selected from a nationwide dementia epidemiological study conducted in South Korea. Global cognitive function was assessed by the Korean version of the Mini-Mental State Examination (MMSE-KC).
Purpose: To investigate age-related differences in the relationships among at-risk alcohol consumption, alcohol use disorder (AUD), and psychological distress with a special focus on older adults.
Methods: We used a nationwide cross-sectional study of a representative sample of community-dwelling adults from the Korean Epidemiologic Catchment Area study for psychiatric disorders conducted by door-to-door interviews. The Korean version of the Composite International Diagnostic Interview was applied.
Background: Panic disorder (PD) and major depressive disorder (MDD) can occur concurrently, despite different clinical manifestations. Because MDD and PD patients tend to have more complicated conditions, understanding the co-occurrence and pattern of these conditions is important. Here, we investigated the influence of PD and MDD on each other, with respect to time interval.
