Human Rights of Persons With Mental Illness After the Korean Mental Health Act Revision: A Qualitative Study.

After the Constitutional Court of Korea ruled that the provision of involuntary admissions was unconstitutional, as it violates personal freedom, the Mental Health and Welfare Act was amended in 2016. The current study explores involuntary admission and discharge experiences, after the law's revision, from a patient-centered perspective and suggests future directions to protect human rights. Data were collected from seven persons with mental illness and three family members through in-depth individual interviews and analyzed using thematic analysis. Persons with mental illness were still not guaranteed full autonomy and the right to receive proper treatment due to lack of mental health resources. The burden on family caregivers was amplified by stricter admission requirements. These results indicate the need for human rights-friendly emergency services, including peer crisis shelters and procedural assistance services. The government should develop community-based mental health services to ensure continuity of care without imposing public responsibility on family members.

Variations in hip fracture inpatient care in Japan, Korea, and Taiwan: an analysis of health administrative data.

BACKGROUND: Little is known about hip fracture inpatient care in East Asia. This study examined the characteristics of patients, hospitals, and regions associated with delivery of hip fracture surgeries across Japan, Korea, and Taiwan. We also analyzed and compared how the resource use and a short-term outcome of the care in index hospitals varied according to factors in the respective health systems. METHODS: We developed comparable, nationwide, individual-level health insurance claims datasets linked with hospital- and regional-level statistics across the health systems using common protocols. Generalized linear multi-level analyses were conducted on length of stay (LOS) and total cost of index hospitalization as well as inpatient death. RESULTS: The majority of patients were female and aged 75 or older. The standardized LOS of the hospitalization for hip fracture surgery was 32.5 (S.D. = 18.7) days in Japan, 24.7 (S.D. = 12.4) days in Korea, and 7.1 (S.D. = 2.9) days in Taiwan. The total cost per admission also widely varied across the systems. Hospitals with a high volume of hip fracture surgeries had a lower LOS across all three systems, while other factors associated with LOS and total cost varied across countries. CONCLUSION: There were wide variations in resource use for hip fracture surgery in the index hospital within and across the three health systems with similar social health insurance schemes in East Asia. Further investigations into the large variations are necessary, along with efforts to overcome the methodological challenges of international comparisons of health system performance.

Routine Screening and Consultation Facilitate Improvement of Metabolic Syndrome.

This randomized controlled trial study aimed to investigate the effects of a lifestyle intervention on metabolic syndrome (MetS) among middle-aged Koreans. A total of 243 middle-aged Koreans with MetS were randomly assigned to either of 2 types of lifestyle intervention for MetS and followed for 12 months. Health examinations and interventions were implemented at 16 regional branch facilities of a Korean medical institution from 2010, following the NCEP-ATP III criteria and recommendations. Lifestyle intervention (LI) group (n = 137) participated in a 12-week multi-component intervention including individual counseling, group sessions, and self-help materials. Basic usual intervention (BI) group (n = 106) was provided with one-page health information sheet on MetS and MetS management at baseline. Prevalence of MetS and each of MetS components, except for low HDL-cholesterol, in both groups were significantly reduced and maintained after the intervention. Notably, prevalence of hypertension and abdominal obesity continued to improve during the follow-up period. Between-group differences in results were not found. Both interventions were effective when they were accompanied with repeated check-ups and notification of MetS status. It is recommended to design clear guidelines for the notification of MetS after MetS screening and to encourage checking MetS status periodically for effective MetS management (KCT 0000446).

Association between Endoscopist Volume and Interval Cancers after Colonoscopy: Results from the National Colorectal Cancer Screening Program in Korea.

Purpose: The rate of interval colorectal cancer (iCRC) is now accepted as a key performance indicator of organized colorectal cancer (CRC) screening programs. We aimed to examine the association between endoscopist volumes and the rate of iCRC among individuals with a positive fecal immunochemical test (FIT) within a nationwide population-based CRC screening program. Materials and Methods: Individuals aged ≥50 years who underwent colonoscopy after a positive FIT from January 1, 2019 until December 31, 2020 in the Korean National Cancer Screening Program (KNCSP) were enrolled. We converted the data into per-endoscopist screening results, calculated the iCRC rates per endoscopist, and compared them to the previous year's annual volume that was divided into five groups (V1, 1-9; V2, 10-29; V3, 30-59; V4, 60-119; V5, ≥120). Results: A total of 10,412 endoscopists performed 216,907 colonoscopies. Overall, the average rate of iCRC per endoscopist was 8.46 per 1,000 examinations. Compared with the group with the highest volume (V5 group), the rate of iCRC was 2.21 times higher in the V1 group. Similar trends were observed in the other groups (V2: Relative risks [RR], 2.15; 95% Confidence Interval [CI], 1.57-2.94; V3: RR, 1.56, 95% CI, 1.15-2.13; V4: RR, 1.18; 95% CI, 0.83-1.67). Conclusion: The findings emphasize that endoscopists with lower procedure volumes have higher risks of interval cancer being missed or undetected. To maximize the preventative impact of colonoscopy for colorectal cancer, this issue should be addressed by monitoring endoscopist volumes and variations in performances.

Explaining Variations in Long-term Care Use and Expenditures Under the Public Long-term Care Insurance Systems: A Case Study Comparison of Korea and Japan.

BACKGROUND: Establishing universal coverage of formal long-term care (LTC) services is an urgent policy need for aging populations that requires efficient management of quality and financing. Although current variation in LTC service use between and within countries suggests the potential for improvement by efficient management, this topic remains underexamined. We aimed to identify the sources of variance in LTC use and expenditures through a unique cross-country comparison of Japan and South Korea, which have formal public LTC insurance (LTCI) schemes that are analogous but have unique operational and demographic structures. METHODS: Taking administrative regions as the unit of analysis, we assembled data on the LTC utilization rate of people aged ≥65 years, and expenditures per recipient from 2013 to 2015 as the outcome variables. Explanatory variables included demand-related factors, such as regional demographic and economic conditions, and supply characteristics derived from existing public databases. We conducted weighted least squares regression with fixed effects for the pooled data and used Blinder-Oaxaca decomposition to identify sources of outcome variance between the two countries. RESULTS: The average LTC utilization rate was 6.8% in Korea and 18.2% in Japan. Expenditures per recipient were approximately 1.4 times higher in Japan than in Korea. The difference in the utilization rate was mostly explained by between-country differences in supply- and demand-related factors, whereas the difference in expenditures per recipient was largely attributed to unobserved country-specific factors. CONCLUSION: The current findings suggest that LTC utilization is determined largely by the demographic and functional characteristics of older people, whereas expenditures are more likely affected by institutional factors such as the insurance governance scheme and the policy choice of the target population segment and coverage. The results suggest that strategic choice of LTC institutional schemes is required to ensure financial sustainability to meet changing demands caused by population aging.

The Evaluation of Web-Based Communication Interventions to Support Decisions About COVID-19 Vaccination Among Patients With Underlying Medical Conditions: Protocol for a Randomized Controlled Trial.

BACKGROUND: The timeliness of raising vaccine acceptance and uptake among the public is essential to overcoming COVID-19; however, the decision-making process among patients with underlying medical conditions is complex, leading individuals to vaccine hesitancy because of their health status. Although vaccine implementation is more effective when deployed as soon as possible, vaccine hesitancy is a significant threat to the success of vaccination programs. OBJECTIVE: This study aims to evaluate the effectiveness of a communication tool for patients with underlying medical conditions who should decide whether to receive a COVID-19 vaccine. METHODS: This 3-arm prospective randomized controlled trial will test the effect of the developed communication intervention, which is fully automated, patient decision aid (SMART-DA), and user-centered information (SMART-DA-α). The web-based intervention was developed to help decision-making regarding COVID-19 vaccination among patients with underlying medical conditions. Over 450 patients will be enrolled on the web from a closed panel access website and randomly assigned to 1 of 3 equal groups stratified by their underlying disease, sex, age, and willingness to receive a COVID-19 vaccine. SMART-DA-α provides additional information targeted at helping patients' decision-making regarding COVID-19 vaccination. Implementation outcomes are COVID-19 vaccination intention, vaccine knowledge, decisional conflict, stress related to decision-making, and attitudes toward vaccination, and was self-assessed through questionnaires. RESULTS: This study was funded in 2020 and approved by the Clinical Research Information Service, Republic of Korea. Data were collected from December 2021 to January 2022. This paper was initially submitted before data analysis. The results are expected to be published in the winter of 2023. CONCLUSIONS: We believe that the outcomes of this study will provide valuable new insights into the potential of decision aids for supporting informed decision-making regarding COVID-19 vaccination and discovering the barriers to making informed decisions regarding COVID-19 vaccination, especially among patients with underlying medical conditions. This study will provide knowledge about the common needs, fears, and perceptions concerning vaccines among patients, which can help tailor information for individuals and develop policies to support them.

Institutional Variance in Mortality after Percutaneous Coronary Intervention for Acute Myocardial Infarction in Korea, Japan, and Taiwan.

BACKGROUND: Although there have been studies that compared outcomes of patients with acute myocardial infarction (AMI) across countries, little focus has been placed on institutional variance of outcomes. The aim of the present study was to compare institutional variance in mortality following percutaneous coronary intervention (PCI) for AMI and factors explaining this variance across different health systems. METHODS: Data on inpatients who underwent PCI for AMI in 2016 were obtained from the National Health Insurance Data Sharing Service in Korea, the Diagnosis Procedure Combination (DPC) Study Group Database in Japan, and the National Health Insurance Research Database (NHIRD) in Taiwan. Multilevel analyses with inpatient mortality as the outcome and the hierarchical structure of patients nested within hospitals were conducted, adjusting for common patient-level and hospital-level variables. We compared the intraclass correlation coefficient (ICC) and the proportion of variance explained by hospital-level characteristics across the three health systems. RESULTS: There were 17 351 patients from 160 Korean hospitals, 29 804 patients from 660 Japanese hospitals, and 10 863 patients from 104 Taiwanese hospitals included in the analysis. Inpatient mortality rates were 6.3%, 7.3%, and 6.0% in Korea, Japan, and Taiwan, respectively. After adjusting for patient and hospital characteristics, Taiwan had the lowest variation in mortality (ICC, 1.8%), followed by Korea (2.2%) and then Japan (4.5%). The measured hospital characteristics explained 38%, 19%, and 9% of the institutional variance in Korea, Taiwan, and Japan, respectively. CONCLUSION: Korea, Japan, and Taiwan had similarly uniform outcomes across hospitals for patients undergoing PCI for AMI. However, Japan had a relatively large institutional variance in mortality and a lower proportion of variation explainable by hospital characteristics, compared with Korea and Taiwan.

Improving adaptive behaviors for autistic adults without intellectual disability through executive function training.

Executive functioning (EF) is a cognitive process used to perform various daily activities throughout one's lifespan. Autistic adults without intellectual disabilities (ID) also experience difficulties with EF, which is closely associated with adaptive behaviors. For this reason, it is important to improve adaptive behaviors through enhanced use of EF for autistic adults to transition into adulthood successfully. This study aims to conduct a randomized controlled trial to evaluate the effectiveness of a newly developed and modified intervention program. Thirty autistic adults without ID were randomly assigned to the treatment or waitlist group. The participants and caregivers completed various assessments and self-report questionnaires to measure everyday EF and adaptive behaviors. We performed linear mixed-effect modeling to compare the two groups. Data collected at pre-, middle, post-, and follow-up based on participants who completed the program were used to explore changes across time. While there were significant differences in the EF utility-scale (F=5.46, p = .027) between the treatment and waitlist groups, no group x time interactions were detected in other measures. Everyday EF and adaptive behaviors improved when comparing measurements at different time points (p < .001). Our program is Korea's first evidence-based intervention to improve everyday EF and adaptive behaviors for autistic adults without ID.

Diagnostic validity of Autism Diagnostic Observation Schedule, second edition (K-ADOS-2) in the Korean population.

BACKGROUND: Although the Korean version of the Autism Diagnostic Observation Schedule-2 (K-ADOS-2) is widely being used to diagnose autism spectrum disorder (ASD) in South Korea, no previous study has examined the validity and reliability of all modules of K-ADOS-2 across a wide age range, particularly older children, adolescents, and adults. METHOD: Data from 2,158 participants were included (mean age = 79.7 months; 73.6% male): 1473 participants with ASD and 685 participants without ASD (Toddler Module, n = 289; Module 1, n = 642; Module 2 n = 574; Module 3 n = 411; Module 4, n = 242). Participants completed a battery of tests, including the K-ADOS or K-ADOS-2 and other existing diagnostic instruments. Sensitivity, specificity, area under the receiver operating characteristic (ROC) curve, positive predictive value (PPV), negative predictive value (NPV), Cohen's kappa (k), and agreement with existing diagnostic instruments were computed. Cronbach's α values were also calculated. RESULTS: All developmental cells of the K-ADOS-2 showed sufficient ranges of sensitivity 85.4-100.0%; specificity, 80.4-96.8%; area under the ROC curve, .90-.97; PPV, 77.8-99.3%; NPV, 80.6-100.0%; and k values, .83-.92. The kappa agreements of developmental cells with existing diagnostic instruments ranged from .20 to .90. Cronbach's α values ranged from .82 to .91 across all developmental cells. LIMITATION: The best-estimate clinical diagnoses made in this study were not independent of the K-ADOS-2 scores. Some modules did not include balanced numbers of participants in terms of gender and diagnostic status. CONCLUSION: The K-ADOS-2 is a valid and reliable instrument in diagnosing ASD in South Korea. Future studies exploring the effectiveness of the K-ADOS-2 in capturing restricted, repetitive behaviors and differentiating ASD from other developmental disabilities are needed.

Effects of the Mental Health and Welfare Law revision on schizophrenia patients in Korea: an interrupted time series analysis.

BACKGROUND: High rates of involuntary hospitalization and long lengths of stay have been problematic in Korea. To address these problems, the Mental Health and Welfare Law was revised in 2016, mainly to protect patient rights by managing involuntary admissions. The aim of this study was to evaluate the impact of the revised Mental Health and Welfare Law on deinstitutionalization by using routinely collected data from hospital admissions and continuity of mental health service use after hospital discharge as proxy measures of deinstitutionalization. METHODS: We used monthly-aggregated claims-based data with a principal or secondary diagnosis of schizophrenia from 2012 to 2019, collected by the National Health Insurance Service. Outcome variables included rates of first admission; discharges; re-admissions within 7, 30, and 90 days; outpatient visits after discharge within 7 and 30 days; and continuity of visits, at least once a month for 6 months after discharge. Using interrupted time series analysis, we estimated the change in levels and trends of the rates after revision, controlling for baseline level and trend. RESULTS: There was no significant change in first admission and discharge rates after the revision. Immediately after the revision, however, the rates of re-admission within 7 and 30 days dropped significantly, by 2.24% and 1.99%, respectively. The slopes of the re-admission rate decreased significantly, by 0.10% and 0.14%, respectively. The slopes of the re-admission rate within 90 days decreased (0.001%). The rates of outpatient visits within 7 and 30 days increased by 1.98% and 2.72%, respectively. The rate of continuous care showed an immediate 4.0% increase. CONCLUSIONS: The revision had slight but significant effects on deinstitutionalization, especially decreasing short-term re-admission and increasing immediate outpatient service utilization.

Validating the Autism Diagnostic Interview-Revised in the Korean Population.

OBJECTIVE: This study aimed to examine the validity of the Korean version of the Autism Diagnostic Interview-Revised (K-ADI-R) and determine its efficacy in identifying individuals with autism spectrum disorder (ASD). METHODS: Data were pooled from several past and ongoing studies as well as clinical records acquired at Seoul National University Bundang Hospital from 2008 to 2017. The K-ADI-R were administered and scored by trained research reliable examiners. Measurements to investigate the validity of the K-ADI-R was through sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and Cohen's kappa. RESULTS: A total of 1,271 (age 88.9±62.42 months, male=927) participants were included. The K-ADI-R yielded strong psychometric properties with high sensitivity (86.06-99.27%), specificity (84.75-99.55%), PPV (92.33-99.72%), and NPV (79.43-98.64%). There were significant differences in item scores across the K-ADI-R diagnostic algorithm regardless of age and sex (p<0.001). Agreement between the K-ADI-R and other ASD related measurements ranged between levels of good to excellent. CONCLUSION: Despite language or cultural boundaries, the K-ADI-R demonstrated high levels of sensitivity, specificity, PPV, and NPV within a wide range of participants; hence, suggesting promising usage as a valuable diagnostic instrument for individuals with ASD.

A Randomized Controlled Trial of the Korean Version of the Program for the Education and Enrichment of Relational Skills for Young Adults (PEERS®-YA-K) With Autism Spectrum Disorder: A Pilot Study.

Evidence-based social skills interventions for young adults are limited, despite social difficulties in autism spectrum disorder (ASD) persisting after transition to adulthood. The Program for the Education and Enrichment of Relational Skills for Young Adults (PEERS®-YA) is an evidence-based intervention found to be effective in improving relational skills in young adults with ASD. To translate the original American version of the PEERS®-YA treatment manual into Korean, intensive interviews were performed. Based on results from interviews, several rules of dating etiquette and social activities were modified to be culturally sensitive and linguistically appropriate. Next, young adults diagnosed with ASD (18-35 years of age; IQ > 70) and their social coaches were recruited for the randomized controlled trial (RCT). Participants were randomly assigned either to a treatment group (TG; n = 19) or a delayed treatment group (DTG; n = 18). In the analysis of group differences in the TG and DTG, social skills knowledge was improved. The within group analyses showed positive effects of improving social skills knowledge on reducing depression and anxiety symptoms. After modest cultural adaptations focusing on dating and social activities, the implementation of the PEERS®-YA-K was found feasible for the Korean community. This is one of only a few cross-cultural validation trials establishing evidence-based treatment in young adults with ASD. Clinical Trial Registration: This trial was registered at ClinicalTrials.gov, identifier: NCT03310775.

Short caregiver interview and play observation for early screening of autism spectrum disorder: Behavior development screening for toddlers (BeDevel).

This study validates behavior development screening for toddlers (BeDevel), which utilizes a combination of short caregiver interviews (BeDevel-I) and semistructured play observations (BeDevel-P). The data of 431 toddlers (male 66.2%; mean age (SD) = 29.11 (8.59) months; ASD, n = 201; developmental delay, n = 46; typically developing, n = 184), aged 18 ~ 42 months, were included in the validation of BeDevel. The best clinical estimate diagnosis, screening rate, validity, sensitivity, and reliability of BeDevel were determined based on data cross-sectionally collected using BeDevel and existing diagnostic/screening instruments: autism diagnostic observation schedule (ADOS), autism diagnostic interview (ADI-R), Vineland adaptive behavior scales-II (VABS-II), social response scales (SRS), sequenced language scale for infants (SELSI), Korean childhood autism rating scale (K-CARS), and Korean social communication questionnaire (K-SCQ). The k values of BeDevel-I and BeDevel-P were 0.055 ~ 0.732 and 0.291 ~ 0.752, respectively. Items related to social referencing in BeDevel-P had a particularly high diagnostic validity (k = 0.483 ~ 0.684). Reliabilities of BeDevel-I and BeDevel-P were sufficient (Cronbach's alpha = 0.86 ~ 0.88 and 0.92 ~ 0.95, respectively). BeDevel-I and BeDevel-P showed high sensitivity (BeDevel-I: 85.00 ~ 89.29%; BeDevel-P: 85.00 ~ 91.75%), specificity (BeDevel-I: 77.55 ~ 89.55%; BeDevel-P: 85.09 ~ 97.01%), PPV (BeDevel-I: 70.83 ~ 88.54%; BeDevel-P: 81.52 ~ 94.68%), and NPV (BeDevel-I: 76.00 ~ 95.24%; BeDevel-P: 84.62 ~ 95.45%). The agreement between the composite BeDevel score and ADOS, ADI-R, K-CARS, and K-SCQ was >67.6% (range = 67.6 ~ 90.8%). Combining a short caregiver interview and direct play observation is a valid and reliable screening process. More studies on social referencing as an important early marker are needed. BeDevel can be utilized as a secondary screening instrument before diagnostic confirmation in clinical and community settings. LAY SUMMARY: BeDevel, which consists of a short caregiver interview and direct play observation, is a valid and reliable screening instrument for autism spectrum disorder (ASD). We suggest that BeDevel can be utilized as a secondary instrument before administering diagnostic assessments in clinical and community settings. More studies examining social referencing as a potential behavioral marker of ASD are needed.

Unwanted effects of risk notification for breast cancer regarding intention toward mammography utilization.

OBJECTIVE: This study was conducted to explore the possible influence of risk notification regarding breast cancer on the intention of women to undergo mammography. METHODS: This study employed an uncontrolled before-after design. A baseline survey was conducted in a random sample of 1000 women to examine the sociodemographic variables, breast cancer risk factors, and screening-related variables. All subjects received the findings of a personalized health-risk appraisal (HRA) following the baseline interview. After 2 months of the baseline survey, a survey was conducted in 855 women to assess whether the intention of undergoing mammography had changed. Thus, the modification in the intention by communicating the individual risk status was assessed. RESULTS: There was an overall increase from baseline to post-intervention in the number of subjects with the intention of undergoing mammography. Women in the contemplation and action stages who had intention toward mammography utilization at baseline showed decreased intention regarding mammography. After intervention in the form of HRA to promote mammography utilization, it was determined that young age, being married, being in neither the precontemplation nor the relapse stage, and having one or more risk factors of breast cancer were the predictors of intention to undergo mammography. CONCLUSIONS: Our findings indicate that communicating the risk status by HRA service can have a negative effect in the promotion of health-conscious behavior. The selection of the appropriate type of intervention using HRA to promote mammography utilization in the target group will be enhanced by taking into account the risk status of each client.

Convenience Store Use and the Health of Urban Adolescents in Seoul, South Korea.

To improve urban adolescents' dietary behaviors and health, factors that influence them to buy meals in convenience stores with regard to urban food environments must be determined. This study investigated the factors which influence adolescents' substitution of meals with convenience store meals and its impact on their health in Seoul (South Korea). Multilevel analysis and logistic regression analysis were conducted using data from the Korea Youth Risk Behavior Survey, a national health survey with a representative sample of Korean adolescents. Among 17,624 teenagers who responded to surveys in 2017 and 2019, 30.5% of them substituted meals with convenience store meals more than three times a week. Girls and students with a lower family economic level were more likely to frequently consume food from convenience stores. Unhealthy lifestyles and poor mental health status also influenced their decisions to substitute meals with convenience store food. Those who frequently consumed meals from convenience stores were more likely to have unhealthy lifestyles, featuring bad diets, smoking, drinking, and sedentary behaviors. They also reported significantly poorer self-rated health and mental health. To promote healthy lifestyles among adolescents, efforts to raise awareness and develop supportive environments for healthy diets are strongly recommended.

Gender-differences in predictors for time to metabolic syndrome resolution: A secondary analysis of a randomized controlled trial study.

Understanding gender differences in health-related behaviors and their impacts is a crucial aspect of effective primary care. We studied gender-based differences in predictors of metabolic syndrome (MetS) resolution among newly diagnosed MetS patients. This study was a secondary analysis of a prospective clinical trial study comprising of 637 middle-aged and older adults (226 men and 411 women) who underwent a regular health checkup and were newly diagnosed with MetS at 16 different health clinics of 14 metropolitan cities and provinces. We conducted Cox proportional hazard analysis to estimate cumulative probability of MetS resolution within a 12-month observation period. Among the 637 patients, 47.6% of participants achieved MetS resolution. The resolution rate was similar among men and women (44.7% and 49.1%, respectively, P = 0.320). Low household income (Hazard ratio = 2.62, 95% confidence interval: 1.13-6.08) and current employment (2.29, 1.26-4.13) were associated with a higher cumulative probability of MetS resolution in men than in women. For women, however, longer sleeping hours (1.18, 1.04-1.34) and living with a partner (1.58, 1.06-2.35) were positive predictors of MetS resolution. Being overweight (0.63, 0.44-0.89) was associated with lower cumulative probability of MetS resolution in women than in men. The factors associated with cumulative probability of MetS resolution within the 12-month follow-up were different between men and women. These findings facilitate further exploration on gender-based differences in risk factors for less optimal improvements in MetS.

Comparison of satisfaction with cancer screening at mobile van and static sites: National Cancer Screening Program in Korea.

OBJECTIVES: Our objectives were to evaluate participant satisfaction in the National Cancer Screening Program (NCSP) and to examine differences in satisfaction between mobile vans and static sites. METHODS: A total of 243 967 participants who were screened by NCSP between January and May 2007 were eligible for the study. Of these, 3416 samples were randomly chosen and stratified by the type of cancer screened and screening unit. A telephone survey was conducted in July 2007, and 1672 participants (48.9%) were responded. The questionnaire included participant satisfaction with screening, screening service use and demographic data. Five multiple regression models were used to determine the relation between screening location (mobile van or static site) and each of five satisfaction measures (information transfer, staff interpersonal skills, privacy protection, physical surroundings and general satisfaction). RESULTS: Of the participants, 764 (45.7%) were screened at a mobile van and 908 (54.3%) at a static site. Relatively high scores were reported for all satisfaction measures, but satisfaction with screening at a mobile van was lower than that at a static site. Even after adjusting for potential confounders, screening at a mobile van was significantly associated with lower satisfaction for information transfer (P = 0.005), staff interpersonal skills (P = 0.025), privacy protection (P = 0.019), physical surroundings (P < 0.001) and general satisfaction (P < 0.001). CONCLUSIONS: Improving the satisfaction with and quality of mobile screening services is important to increase compliance and achieve the aims of the NCSP. Therefore, further efforts such as quality assurance or continuous monitoring are required.

Differences in Personality, Defense Styles, and Coping Strategies in Individuals with Depressive Disorder According to Age Groups Across the Lifespan.

OBJECTIVE: This study aimed to examine the differences in personality, defense style, and coping styles among patients with depression according to age groups. METHODS: A total of 211 participants ranging from 19 to 81 years old were recruited for the study. To assess participants' five dimensions of personality, the Neuroticism-Extraversion-Openness Personality Inventory-Revised (NEO-PI-R) was administered. In addition, the Korean-Defense Style Questionnaire and the Korean version of the coping checklist were administered to examine the defense and coping style. RESULTS: In the analysis of NEO-PI-R, the mean value of Agreeableness, Conscientiousness, and Neuroticism showed significant differences between the young adult age group (20-34 years) and the late middle age group (50-64 years) (p<0.05). The young age group used more immature defense styles and made less use of problem-focused coping strategy than the old age patients (65 years and older) (p<0.05). CONCLUSION: In the young age group associations with lower Agreeableness and Conscientiousness, as well as higher Neuroticism than the late middle age group were observed. Moreover, the young age group had a higher usage of immature defense style, and restricted use of problem-focused coping style than other age groups.

The Feasibility and Validity of Autism Spectrum Disorder Screening Instrument: Behavior Development Screening for Toddlers (BeDevel)-A Pilot Study.

Although early screening is critical for individuals with autism spectrum disorder (ASD) in order to receive early intervention and improve function later in life, screening is often delayed. Limitations of existing screening instruments, and the need for a culturally appropriate early screening tool in Korean children, led us to develop Behavior Development Screening for Toddlers (BeDevel). The BeDevel assessment consists of two parts: BeDevel-Interview, a structured interview measure for parents/primary caregivers; and BeDevel-Play, a play-based semi-structured observational measure in children. To examine the feasibility and validity of BeDevel, 155 children (N = 75 ASD, N = 55 typical development, N = 25 developmentally delayed) aged 18-42 months (M = 31.54 months, SD = 7.60) were examined through parent-reported screening questionnaires, BeDevel, and standard diagnostic assessments. When BeDevel items were analyzed using Cohen's kappa statistics, most items in BeDevel-Interview and all items in BeDevel-Play were reasonably consistent with diagnoses. We identified primary items, which were significantly interacted with actual diagnosis in the chi-squared test (P < 0.05, range = 0.000-0.032). Using cutoff numbers of items determined using the receiver operating characteristics curve, BeDevel showed satisfactory levels of sensitivity (83.33%-100%), specificity (81.25%-100%), positive predictive values (80.65%-100%), and negative predictive values (83.87%-100%), as well as high internal consistency (Cronbach's α = 0.866-959). The agreement between BeDevel and most other screening/diagnostic instruments was moderate (k = 0.419-1.000). These results suggest that BeDevel can be a useful instrument for early screening of ASD.

LAY SUMMARY: Although early screening is critical for individuals with autism spectrum disorder (ASD) in order to receive early intervention and improve function later in life, screening is often delayed. Limitations of existing screening instruments and the need for a culturally appropriate early screening tool in Korean children led us to develop Behavior Development Screening for Toddlers (BeDevel). The BeDevel assessment consists of two parts: BeDevel-Interview, a structured interview measure for parents/primary caregivers; and BeDevel-Play, a play-based, semi-structured observational measure in children. In order to test the feasibility and validity of BeDevel, we analyzed preliminary data of total 155 children aged 18-42 months, examined through parent-reported screening questionnaires, BeDevel, and standard diagnostic assessments. When individual items were analyzed, responses of all BeDevel-Interview items and of most BeDevel-Play items well matched actual diagnoses, and we identified primary items, which were particularly useful in differentiating between the ASD group and the non-ASD group. With the optimal screening criteria determined, the BeDevel was able to identify individuals with a diagnosis of ASD and those without it, all at satisfactory levels. Lastly, BeDevel items were closely related as a set, and the BeDevel screening results were reasonably consistent with the results of most other screening/diagnostic instruments. These results suggest that BeDevel can be a useful instrument for early screening of ASD.

Influence of Highly Accessible Urban Food Environment on Weight Management: A Qualitative Study in Seoul.

We explored the characteristics of the food environment and its influence on weight management in Seoul, Korea. Photo elicitation interviews were conducted with 73 participants who took three photographs per topic related to their food environment and discussed these photographs in groups. Through thematic analysis, we identified four themes concerning participants' perceptions of the food environment and weight management: (1) "convenience comes first," (2) "tempting food environment," (3) "alcohol and anju," and (4) "burden of individual effort to manage weight." A systematic change toward an environment supportive of healthy eating and weight management is recommended.
