Recently, CBT-based digital therapy has been developed and used for the treatment of various psychiatric disorders, including insomnia, depression, anxiety and panic disorders, and alcohol/drug addiction. In the United States, the first game-based digital therapy for ADHD has also received FDA approval and is being used for the treatment of children and adolescents with ADHD.

We conducted a randomized controlled study to examine the effectiveness of a digital therapeutic (model named ‘ADAM-101’) for children with ADHD in Korea, which was developed by Dragonfly GF Co., Ltd.”

Participants are 18 children with ADHD, aged 7 to 13 years, who are visiting the Department of Child and Adolescent Psychiatry at Seoul National University Children’s Hospital in Seoul, Korea. ADHD children with an IQ of 70 or above, who are currently taking stimulants and do not have other pediatric psychiatric disorders such as depression, anxiety disorders, tic disorders, ASD, were included in the study. They were randomly assigned to either the combined treatment group (medication + digital therapy, n = 9) or the medication-only group (n = 9). The digital therapy program was conducted using a tablet PC for 25 minutes a day, 5 days a week, for 4 weeks. Before starting the study, permission was obtained from the Institutional Review Board of Seoul National University Hospital. As a primary outcome measure, the Korean version of the Continuous Performance Test (KAT) was administered individually to the ADHD children by child clinical psychologists to assess inattention, impulsivity, and processing speed, after obtaining written agreement to participate in the study. Additionally, the Korean version f the ADHD Rating Scale-5 (K-ARS-5) was administered to the parents of the ADHD children.

We have not yet completed the study. Currently, out of the 18 ADHD children, 8 have completed the training and both pre- and post-assessments. All training and evaluations are expected to be completed by early October, and an analysis to verify the effectiveness of the digital therapeutic will be conducted in mid-October. Since this was not a double-blind study, we observed that, based on some children’s CPT and K-ARS-5 results, children in the combined treatment group tended to show a reduction in omission and commission errors on the CPT compared to those in the medication-only group. Additionally, there was a trend towards a reduction in inattention and hyperactivity-impulsivity scores on the K-ARS-5 in the combined treatment group.

Despite being conducted with a small sample, these results suggest the potential efficacy of the digital therapeutic (model named ‘ADAM-101’) for Korean ADHD children, indicating its potential clinical usefulness as an adjunctive treatment tool for ADHD children

Cancer is a life-changing experience, and side effects from treatment can make it difficult for survivors to return to their pre-cancer “normal life.” We explored the “new normal” and barriers to achieving it among lung cancer survivors who underwent surgery.

Semi-structured interviews were conducted with 32 recurrence-free non–small cell lung cancer survivors. We asked survivors how life had changed; how they defined the “new normal”; barriers that prevent them from achieving a “normal” life; and unmet needs or support for normalcy. Thematic analysis was performed.

Defining “new normal” subjectively depends on an individual’s expectation of recovery: (1) being able to do what they want without pain or discomfort; (2) being able to do activities they could accomplish before their surgery; and (3) being able to work, earn money, and support their family. We found that (1) persistent symptoms, (2) fear of cancer recurrence, (3) high expectations in recovery, and (4) psychosocial stress and guilty feelings were barriers to achieving a “new normal.” The needs and support for normalcy were information on expected trajectories, postoperative management, and support from family and society.

Survivors defined the “new normal” differently, depending on their expectations for recovery. Informing survivors about the “new normal” so they could expect possible changes and set realistic goals for their life after cancer. Health professionals need to communicate with survivors about expectations for “normality” from the beginning of treatment, and it should be included in comprehensive survivorship care.

Previous evidence on antidepressant medication and cardiovascular disease (CVD) among patients with posttraumatic stress disorder (PTSD) has been inconclusive. We estimated the association between antidepressant medication and CVD by applying a marginal structural model.

We analyzed medical utilization records of 27 170 people with PTSD without prior major cardiovascular events in the Korean National Health Insurance Database (NHID). PTSD and CVD were defined in accordance with the recorded ICD-10 diagnostic codes. We acquired information on antidepressant use from the NHID and categorized them by medication type. A composite major adverse cardiovascular events (MACE) outcome was defined as coronary artery disease with revascularization, ischaemic stroke, and/or haemorrhagic stroke. We used inverse probability of treatment weighting to estimate the parameters of a marginal structural discrete-time survival analysis regression model, comparing the resulting estimates to those derived from traditional time-fixed and time-varying Cox proportional hazards regression. We calculated cumulative daily defined doses to test for a dose–response relationship.

People exposed to antidepressants showed a higher hazard of MACE [hazard ratio (HR) 1.34, 95% confidence interval (CI) 1.18–1.53]. The estimated effects were strongest for selective serotonin reuptake inhibitors (HR 1.24, 95% CI 1.08–1.44) and TCAs (HR 1.33, 95% CI 1.13–1.56). Exposure to serotonin-norepinephrine reuptake inhibitors did not appear to increase the risk of MACE. People exposed to higher doses of antidepressants showed higher risk of MACE.

In a national cohort of people with PTSD, exposure to antidepressant medications increased the risk of MACE in a dose–response fashion.

This study aims to identify factors associated with divorce following breast cancer diagnosis and measures the impact of divorce on the quality of life (QoL) of patients.

We used cross-sectional survey data collected at breast cancer outpatient clinics in South Korea from November 2018 to April 2019. Adult breast cancer survivors who completed active treatment without any cancer recurrence at the time of the survey (N = 4,366) were included. The participants were classified into two groups: “maintaining marriage” and “being divorced,” between at the survey and at the cancer diagnosis. We performed logistic regression and linear regression to identify the factors associated with divorce after cancer diagnosis and to compare the QoL of divorced and nondivorced survivors.

Approximately 11.1/1,000 of married breast cancer survivors experienced divorce after cancer diagnosis. Younger age, lower education, and being employed at diagnosis were associated with divorce. Being divorced survivors had significantly lower QoL (Coefficient [Coef] = −7.50; 95% CI = −13.63, −1.36), social functioning (Coef = −9.47; 95% CI = −16.36, −2.57), and body image (Coef = −8.34; 95% CI = −6.29, −0.39) than survivors who remained married. They also experienced more symptoms including pain, insomnia, financial difficulties, and distress due to hair loss.

Identifying risk factors of divorce will ultimately help ascertain the resources necessary for early intervention.

To evaluate the impact of a vancomycin-resistant Enterococcus (VRE) screening policy change on the incidence of healthcare-associated (HA)-VRE bacteremia in an endemic hospital setting.

A quasi-experimental before-and-after study.

A 1,989-bed tertiary-care referral center in Seoul, Republic of Korea.

Since May 2010, our hospital has diminished VRE screening for admitted patients transferred from other healthcare facilities. We assessed the impact of this policy change on the incidence of HA-VRE bacteremia using segmented autoregression analysis of interrupted time series from January 2006 to December 2014 at the hospital and unit levels. In addition, we compared the molecular characteristics of VRE blood isolates collected before and after the screening policy change using multilocus sequence typing and pulsed-field gel electrophoresis.

After the VRE screening policy change, the incidence of hospital-wide HA-VRE bacteremia increased, although no significant changes of level or slope were observed. In addition, a significant slope change in the incidence of HA-VRE bacteremia (change in slope, 0.007; 95% CI, 0.001–0.013; P = .02) was observed in the hemato-oncology department. Molecular analysis revealed that various VRE sequence types appeared after the policy change and that clonally related strains became more predominant (increasing from 26.1% to 59.3%).

The incidence of HA-VRE bacteremia increased significantly after VRE screening policy change, and this increase was mainly driven by high-risk patient populations. When planning VRE control programs in hospitals, different approaches that consider risk for severe VRE infection in patients may be required.

Network approach has been applied to a wide variety of psychiatric disorders. The aim of the present study was to identify network structures of remitters and non-remitters in patients with first-episode psychosis (FEP) at baseline and the 6-month follow-up.

Participants (n = 252) from the Korean Early Psychosis Study (KEPS) were enrolled. They were classified as remitters or non-remitters using Andreasen's criteria. We estimated network structure with 10 symptoms (three symptoms from the Positive and Negative Syndrome Scale, one depressive symptom, and six symptoms related to schema and rumination) as nodes using a Gaussian graphical model. Global and local network metrics were compared within and between the networks over time.

Global network metrics did not differ between the remitters and non-remitters at baseline or 6 months. However, the network structure and nodal strengths associated with positive-self and positive-others scores changed significantly in the remitters over time. Unique central symptoms for remitters and non-remitters were cognitive brooding and negative-self, respectively. The correlation stability coefficients for nodal strength were within the acceptable range.

Our findings indicate that network structure and some nodal strengths were more flexible in remitters. Negative-self could be an important target for therapeutic intervention.

The Internet is commonly used in modern society; however, Internet use may become a problematic behaviour. There is an increasing need for research on problematic Internet use (PIU) and its’ associated risk factors.

This study aims to explore the prevalence and health correlates of problematic Internet use among South Korean adults.

We recruited the participants aged between 18 and 84 years old among the online panel of an online research service. The sample size of the survey was 500. Of these 500 participants, 51.4% (n = 257) were men and 48.6% (n = 243) were women. A participant was classified as a problematic Internet use (PIU) if his/her total score of Young's Internet Addiction Scale (YIA) was above 50. Stress Response Index (SRI), Fagerstrom test for nicotine dependence, lifetime average caffeine consumption, and sociodemographic query form were used in the collection of data. The t test and chi-square test were used for data analysis.

One hundred ninety-seven (39.4%) of the participants was classified into the PIU group. There was no difference of gender and education between PIU and normal users. However, PIU group was younger (mean 39.5 years) than normal users (mean 45.8 years). PIU group was more likely to have high levels of perceived stress, nicotine dependence, and drink more often caffeinated beverages (P < 0.05).

These data indicate that problematic Internet use is associated with perceived stress level, nicotine and caffeine use in South Korean Internet users. More research is needed to better understand the relationship between Internet use and mental health issues.

Little is known about long-term employment outcomes for patients with first-episode schizophrenia-spectrum (FES) disorders who received early intervention services.

We compared the 10-year employment trajectory of patients with FES who received early intervention services with those who received standard care. Factors differentiating the employment trajectories were explored.

Patients with FES (N = 145) who received early intervention services in Hong Kong between 1 July 2001 and 30 June 2002 were matched with those who entered standard care 1 year previously. We used hierarchical clustering analysis to explore the 10-year employment clusters for both groups. We used the mixed model test to compare cluster memberships and piecewise regression analysis to compare the employment trajectories of the two groups.

There were significantly more patients who received the early intervention service in the good employment cluster (early intervention: N = 98 [67.6%]; standard care: N = 76 [52.4%]; P = 0.009). In the poor employment cluster, there was a significant difference in the longitudinal pattern between early intervention and standard care for years 1–5 (P < 0.0001). The number of relapses during the first 3 years, months of full-time employment during the first year and years of education were significant in differentiating the clusters of the early intervention group.

Results suggest there was an overall long-term benefit of early intervention services on employment. However, the benefit was not sustained for all patients. Personalisation of the duration of the early intervention service with a focus on relapse prevention and early vocational reintegration should be considered for service enhancement.

This study aimed to investigate associations among spirituality, coping strategies, quality of life (QOL), and the effects of depression and anxiety thereon in cancer patients.

In total, 237 cancer patients referred to a psycho-oncology clinic at a university hospital in Korea were enrolled. After identifying predictors of patient QOL in a stepwise regression model, we developed a hypothetical path model wherein interpersonal coping was considered as a mediating variable between spirituality (meaning/peace) and QOL and wherein depression and anxiety affected each of these three variables.

The direct effect of spirituality (meaning/peace) on QOL was 36.7%. In an indirect model, interpersonal coping significantly mediated the relationship between spirituality (meaning/peace) and QOL. Depression exerted the largest negative effect on spirituality (meaning/peace), interpersonal coping, and QOL. Anxiety had negative effects on spirituality (meaning/peace) and QOL, but a positive effect on interpersonal coping.

Interpersonal coping strategies work as a partial mediator of the relationship between meaning/peace subscales of spirituality and QOL. Effective management of depression may help in achieving better outcomes associated therewith. Greater attention and efforts to improve social connectedness and meaning of life in spiritual well-being may improve the QOL of cancer patients.

Our objective was to evaluate long-term altered appearance, distress, and body image in posttreatment breast cancer patients and compare them with those of patients undergoing active treatment and with general population controls.

We conducted a cross-sectional survey between May and December of 2010. We studied 138 breast cancer patients undergoing active treatment and 128 posttreatment patients from 23 Korean hospitals and 315 age- and area-matched subjects drawn from the general population. Breast, hair, and skin changes, distress, and body image were assessed using visual analogue scales and the EORTC BR–23. Average levels of distress were compared across groups, and linear regression was utilized to identify the factors associated with body image.

Compared to active-treatment patients, posttreatment patients reported similar breast changes (6.6 vs. 6.2), hair loss (7.7 vs. 6.7), and skin changes (5.8 vs. 5.4), and both groups had significantly more severe changes than those of the general population controls (p < 0.01). For a similar level of altered appearance, however, breast cancer patients experienced significantly higher levels of distress than the general population. In multivariate analysis, patients with high altered appearance distress reported significantly poorer body image (–20.7, CI95% = –28.3 to –13.1) than patients with low distress.

Posttreatment breast cancer patients experienced similar levels of altered appearance, distress, and body-image disturbance relative to patients undergoing active treatment but significantly higher distress and poorer body image than members of the general population. Healthcare professionals should acknowledge the possible long-term effects of altered appearance among breast cancer survivors and help them to manage the associated distress and psychological consequences.

Psychological health is an important issue after disasters. This study aimed to investigate the prevalence of psychological symptoms among 993 residents of Taean District in South Korea after the Hebei Spirit oil spill and to examine determinants of vulnerability in residents’ psychological symptoms.

Symptoms of post-traumatic stress (PTS), depression, suicidal ideation, and anxiety were assessed by questionnaires, and the responses were analyzed by using the survey analysis considering the sampling frame.

Among the study subjects, the symptom prevalences of PTS, depression, suicidal ideation, and anxiety were 19.5%, 22.0%, 2.3%, and 4.2%, respectively, and symptoms were higher in people who were female, were older, were less educated, and had lower family income. People with fishery or related occupations compared to those with unrelated livelihoods and people residing in the vicinity of the oil band in the contaminated coastline showed additively increased symptom risks of PTS. Risk of suicidal ideation was predominantly increased in people with fishery or related occupations compared with those with unrelated livelihoods.

Social supports, including compensation for income loss and community mental health programs, and longer follow-up studies are needed for residents in the communities affected by the Hebei Spirit oil spill. (Disaster Med Public Health Preparedness. 2016;10:51-58)
