Out-of-pocket costs associated with chronic respiratory diseases in Korean adults.

Chronic respiratory diseases (CRDs) are a burden on both individuals and society. While previous literature has highlighted the clinical burden and total costs of care, it has not addressed patients' direct payments. This study aimed to estimate the incremental healthcare costs associated with patients with CRDs, specifically out-of-pocket (OOP) costs. We used survey data from the 2019 Korea Health Panel Survey to estimate the total OOP costs of CRDs by comparing the annual hospitalizations, outpatient visits, emergency room visits, and medications of patients with and without CRDs. Generalized linear regression models controlled for differences in other characteristics between groups. We identified 222 patients with CRDs, of whom 166 were aged 65 years and older. Compared with the non-CRD group, CRD patients spent more on OOP costs (238.3 USD on average). Incremental costs were driven by outpatient visits and medications, which are subject to a coinsurance of 30% or more and may include items not covered by public insurance. Moreover, CRD patients aged 50-64years incurred the highest incremental costs. The financial burden associated with CRDs is significant, and outpatient visits and medications constitute the largest components of OOP spending. Policymakers should introduce appropriate strategies to reduce CRD-associated burdens.

Prevalence and Characteristics by Age and Sex in Pediatric Trigger Digits: Nationwide Analysis Using Korea Health Insurance Dataset.

Pediatric trigger digit (TD) does not appear at birth but is diagnosed after birth by finding a flexion contracture of the thumb or other fingers. The reported incidence of pediatric TDs varies from 0.5 to 5 cases per 1,000 live births without sex-specific predominance. We performed a nationwide large-scale study to determine the prevalence and incidence of pediatric TDs and analyzed operative treatment for pediatric TDs using the National Health Insurance data of South Korea. Patients with pediatric TDs, aged 0-10 years between 2011 and 2020, were included in this study. Children born between 2011 and 2015 were set as the reference population and followed up until 2020. We calculated the prevalence and incidence rates of pediatric TDs according to age and sex and analyzed the operation rate, age at surgery, time interval from initial diagnosis to surgery, and follow-up period. Patient selection and treatment were based on International Classification of Diseases, 10th Revision (ICD-10). The prevalence rates of pediatric TDs ranged from 0.063% to 0.084%. Girls had a higher prevalence rate (0.066%-0.094%) than boys (0.060%-0.075%). The total incidence rate was 77.6/100,000 person-years, and the incidence rate was higher in girls (84.8) than in boys (70.7). Among 2,181,814 children born between 2011 and 2015, 12,729 were diagnosed with pediatric TDs, of which 1,128 (8.9%) underwent operative management. The means of age at initial diagnosis, age at surgery, and the time interval between diagnosis and operation were 2.76 ± 1.91 years, 3.79 ± 2.19 years, and 1.15 ± 1.71 years, respectively. High prevalence and incidence rates of pediatric TDs were found in 2- to 3-year-old patients. Among pediatric patients, 8.9% underwent operative management that was most frequently conducted between 2 and 3 years of age (within 1 year of initial diagnosis).

Relationship between health literacy and health-related quality of life in Korean adults with chronic diseases.

Inadequate health literacy is a risk factor for poor health outcomes and health-related quality of life (HRQoL). So far, the impact of health literacy on HRQoL has been examined for only a few chronic conditions. In this contribution, the relationship between health literacy and HRQoL in Korean adults with chronic conditions is examined using data of the cross-sectional Korea Health Panel Survey from 2021. Health literacy was measured with the 16-item European Health Literacy Survey Questionnaire (HLS-EU-Q16) and HRQoL with the European Quality of Life-5 Dimensions (EQ-5D). Multiple linear regression model was run for the EQ-5D index as the dependent variable. Multiple logistic regression models were implemented for responses to the individual EQ-5D items. 30.8%, 24.6%, and 44.6% of participants had inadequate, marginal, and adequate levels of health literacy, respectively. The EQ-5D index increases with marginal (B = 0.018, p<0.001) and adequate literacy (B = 0.017, p<0.001) compared to inadequate literacy. People with adequate or marginal literacy were more likely to report no problem with mobility (odds ration [OR] = 1.5; p<0.001), self-care (OR = 1.6; p<0.05), and usual activities (OR = 1.6 for adequate; OR = 1.4 for marginal; p<0.01) than those with inadequate literacy. Adequate health literacy was associated with an increased likelihood of having no problem with anxiety and depression (OR = 1.4; p<0.05). In conclusion, inadequate health literacy is prevalent among Korean adults with chronic diseases. Adequate health literacy is associated with better HRQoL and a protective factor for four dimensions of EQ-5D (mobility, self-care, usual activities, and anxiety/depression).

The moderating effect of parenting efficacy on the relationship between child's temperament and parental depression

BackgroundAccording to the Ministry of Health and Welfare's Korean Survey of Children (2018), 13.7% of the primary caregivers experienced depression. Depression experienced by main caregiver negative effect on the development of their children. ObjectiveThis study aims to investigate the moderating effect of parenting efficacy on the relationship between child temperament and parental depression.Participants and setting: A total of 468 participants, including 431 women (92.1%) and 37 men (7.9%) were included in the study. This study analyzed data from the Korean Survey of Children (For Parents, 2018) conducted by the Ministry of Health and Welfare of Korea. MethodsThe survey was conducted from January 7, 2019, to February 28, 2019. In this study, the Emotionality, Activity, and Sociability Scale (EAS), the Center for Epidemiological Studies Depression Scale (CES-D), and The Parenting Sense of Competence Scale (PSOC) were used to measure children's temperament, parental depression, and parenting efficacy. This study used PROCESS Macro 3.5 for SPSS 25.0 to analyze the moderating effect. Additionally, simple regression was conducted to verify the interaction effect. ResultsThe results showed that the emotionality of children is positively related to their parents’ states of depression. Their sociality was negatively associated with parental depression. However, children's activities were not associated with parental depression. Second, parenting efficacy was negatively related to parental depression. Third, parenting efficacy moderated the relationship between the emotionality of children and parental depression. ConclusionThe results of this study suggest that there is a correlation between parent–child interaction, as well as parenting efficacy and parents' depression level. It is particularly significant in that it presents the necessity and theoretical basis for a parenting program.

사업장의 안전보건교육 경험에 따른 불안전한 행동이 안전보건문화에 미치는 영향에 관한 연구

Safety and health education at the workplace is an important way to prevent industrial accidents, and is a basic matter in which workers can participate, and is the employer's obligation. Although the importance of safety training in the workplace is recognized, there is much controversy about its effectiveness in improving on-site operability. Accordingly, this study aims to understand the actual status of safety and health education and determine the impact of unsafe behavior on safety and health culture according to safety and health education experience. It was conducted for the purpose of using basic data to verify and activate the effectiveness of safety and health education in the future. This study conducted a survey of workers at about 150 manufacturing plants from August to December 2022, and 300 people were selected for final analysis. The survey questions were designed to fit the study using questions used in the Occupational Safety and Health Trend Survey(2015) conducted by the Korea Occupational Safety and Health Agency and the risk assessment of safety management consulting organizations. The collected data were subjected to frequency analysis, factor analysis, and multiple regression analysis using SPSS 21.0 program. As a result, workers were aware of the obligation to provide safety and health education, and the experience of regular safety and health education was the highest among safety education. Those who experienced safety education showed that inappropriate management or supervision, negligence during work, unreasonable actions and movements, inappropriate use of equipment and tools, unsafe work performance, and unreasonable work influenced the perception of safety and health culture. For inexperienced people, inadequate management or supervision appeared to affect safety and health culture. Through this study, it was confirmed that awareness of unsafe behavior is formed through education and is a factor that influences safety and health culture. In the future, it will be necessary to provide an opportunity to form a safety and health culture by linking safety and health education to activation within the workplace and field operability. In addition, it seems that more management is needed to make safety and health education a reality and continuously implement it.

Understanding health literacy of deaf persons with hypertension in South Korea: A cross-sectional study.

Health literacy is strongly associated with health inequality among persons with deafness, and hypertension (HTN) is the most prevalent chronic disease among persons with deafness in South Korea. Despite its importance, research regarding the health literacy levels of persons with deafness with HTN in South Korea is lacking. This study aimed to comprehensively assess the health literacy levels of persons with deafness with HTN in South Korea, including linguistic, functional, and internet health literacy. In this descriptive cross-sectional study, 95 persons with deafness with HTN were recruited through facilities associated with the deaf community. From August 2022 to February 2023, data were collected through face-to-face surveys attended by a sign language interpreter and online surveys. The data were analyzed using descriptive statistics and Spearman's correlation. Approximately 62.1% of the participants exhibited a linguistic health literacy level corresponding to less than that of middle school students, and the total percentage correct of functional health literacy was 17.9%. Each domain of internet health literacy was low. Significant correlations were found between some aspects of health literacy. The study's findings highlight the low health literacy levels across various facets among persons with deafness with HTN in South Korea. Based on these findings, several strategies are suggested for developing HTN self-management interventions for persons with deafness. This study contributes to the foundational understanding of health literacy among persons with deafness with HTN in South Korea and provides valuable insights and guidance for developing HTN self-management interventions.

Correlation between Usual Source of Care and Medication Adherence in Patients with Hypertension.

Maintaining a usual source of care (USC), which is crucial for primary healthcare, encompasses initial contact, comprehensive services, coordinated care, and ongoing support. However, limited research exists on the relationship between USC and medication adherence in patients with hypertension. This study aimed to investigate the association between USC and medication adherence among patients with hypertension. Data from the 2nd Korea Health Panel Survey 2020 were analyzed. The final sample consisted of 3,318 participants aged 19 years or older diagnosed with hypertension. USC was categorized into three groups: no USC, place only (without a regular doctor), and regular doctor. Medication adherence was assessed using detailed items (dose, frequency, time, no stop) and a 4-point Likert scale. A logistic regression analysis was conducted with control for relevant variables. Compared to the no USC group, the regular doctor group had significantly higher odds ratios (ORs) for overall perfect/high medication adherence rates: 1.70 (95% confidence interval [CI], 1.42-2.03) and 1.59 (95% CI, 1.14-2.20). Similar results were observed for each adherence item, including prefect dose (OR, 2.14; 95% CI, 1.73- 2.63), frequency (OR, 1.87; 95% CI, 1.53-2.28), time (OR, 1.72; 95% CI, 1.43-2.07), and no stop (OR, 1.56; 95% CI, 1.09-2.23)/high frequency (OR, 2.47; 95% CI, 1.21-5.01), time (OR, 2.30; 95% CI, 1.19-4.44). However, the place only group showed no significant differences in medication adherence except for perfect adherence to dose (OR, 1.35; 95% CI, 1.06-1.71). These findings provide evidence supporting the need for healthcare policies that encourage having a regular doctor in South Korea, which has a healthcare system with limited primary care.

Item difficulty index, discrimination index, and reliability of the 26 health professions licensing examinations in 2022, Korea: a psychometric study.

This study presents item analysis results of the 26 health personnel licensing examinations managed by the Korea Health Personnel Licensing Examination Institute (KHPLEI) in 2022. The item difficulty index, item discrimination index, and reliability were calculated. The item discrimination index was calculated using a discrimination index based on the upper and lower 27% rule and the item-total correlation. Out of 468,352 total examinees, 418,887 (89.4%) passed. The pass rates ranged from 27.3% for health educators level 1 to 97.1% for oriental medical doctors. Most examinations had a high average difficulty index, albeit to varying degrees, ranging from 61.3% for prosthetists and orthotists to 83.9% for care workers. The average discrimination index based on the upper and lower 27% rule ranged from 0.17 for oriental medical doctors to 0.38 for radiological technologists. The average item-total correlation ranged from 0.20 for oriental medical doctors to 0.38 for radiological technologists. The Cronbach α, as a measure of reliability, ranged from 0.872 for health educators-level 3 to 0.978 for medical technologists. The correlation coefficient between the average difficulty index and average discrimination index was -0.2452 (P=0.1557), that between the average difficulty index and the average item-total correlation was 0.3502 (P=0.0392), and that between the average discrimination index and the average item-total correlation was 0.7944 (P<0.0001). This technical report presents the item analysis results and reliability of the recent examinations by the KHPLEI, demonstrating an acceptable range of difficulty index and discrimination index values, as well as good reliability.

Effects of private health insurance on healthcare services during the MERS Pandemic: Evidence from Korea

This study investigates how private health insurance impacted healthcare services during the MERS pandemic in Korea. Using the Korea Health Panel Study (KHPS), this study examines the difference in healthcare utilization between insured and uninsured individuals during the pandemic. If insured individuals use fewer healthcare services than the uninsured during the MERS pandemic, it could be evidence of moral hazard. During the MERS outbreak, the probability of outpatient medical services utilization was lower by 19 % than during non-pandemic periods. All individuals decreased the number of outpatient visits by 7 %. Insured individuals reduced outpatient visits more than the uninsured in response to the MERS pandemic. The increased outpatient utilization by private health insurance could be attributed to both moral hazard and adverse selection. However, given that people with poor health cannot enroll in private health insurance due to the insurance company's screening process, moral hazard leads to increase healthcare utilization rather than adverse selection.

Health Behaviors of Cancer Survivors According to the Employment Status and Occupation: A Cross-Sectional Study.

This study aimed to identify differences in health behaviors according to the employment status and occupation of cancer survivors, as well as to identify risk factors. Using data from the Korea National and Health Nutrition Examination Survey (2008-2018), 1023 cancer survivors aged 19-60 years were classified based on their employment status and occupation, and their health behaviors were comparatively assessed. To investigate the impact of occupational status on the health behaviors of cancer survivors, we performed multivariate adjusted logistic regression analysis. Five hundred fifty-six (54.3%) cancer survivors were engaged in economic activities. After adjusting for various factors, white- and blue-collar workers exhibited an increased risk of obesity. The blue-collar group had a 1.45 times higher risk of non-practice with cancer screening, while the white-collar group had a 0.50 times lower risk of non-practice with health screening. The results provide evidence of the need to support cancer survivors in practicing healthy behaviors according to their employment status and occupation. As cancer survivors' economic activities increase, it is necessary to help them manage their health by predicting any possible health-behavior failures.

Effects of private health insurance on medical expenditure and health service utilization in South Korea: a quantile regression analysis

BackgroundDespite universal health insurance, South Korea has seen a sharp increase in the number of people enrolled in supplemental private health insurance (PHI) during the last decade. This study examined how private health insurance enrollment affects medical expenditure and health service utilization.MethodsUnbalanced panel data for adults aged 19 and older were constructed using the 2016–2018 Korea Health Panel Survey. Quantile regression for medical cost, and quantile count regression for health service utilization were utilized using propensity score-matched data. We included 17 variables representing demographic, socioeconomic, and health information, as well as medical costs and use of outpatient and inpatient care.ResultsWe discovered that PHI enrollees’ socioeconomic and health status is more likely to be better than PHI non-enrollees’. Results showed that private health insurance had a greater effect on the lower quantiles of the conditional distribution of outpatient costs (coefficient 0.149 at the 10th quantile and 0.121 at the 25th quantile) and higher quantiles of inpaitent care utilization (coefficient 0.321 at the 90th quantile for days of hospitalization and 0.076 at the 90th quantile for number of inpatient visits).ConclusionsPHI enrollment is positively correlated with outpatient costs and inpatient care utilization. Government policies should consider these heterogeneous distributional effects of private health insurance.

보건학자 주인호의 감염병 매개 곤충 연구와 미군의 지원, 1945-1969

This paper delves into the body of works produced by Inho Chu, a Korean public health researcher, between the late 1940s and the 1960s, with a particular focus on the impact of the United States military on his research. Chu emerged as a central figure in the process often referred to as “Americanization” of Korean public health in the aftermath of World War II. His professional development as a public health expert was significantly influenced by continuous support from the U.S. military. Chu pursued his education in public health at the University of Michigan under the auspices of the United States Army Military Government in Korea (USAMGIK). Additionally, he received specialized training in medical entomology at the U.S. Army's Hemorrhagic Fever Center during the Korean War. Subsequent to the war, he departed for the U.S. Naval Medical Research Unit 2 in Taiwan (NAMRU-2) to join the transnational network of tropical medicine. Through a detailed exploration of Chu's academic journey, this paper aims to analyze how Chu effectively adapted the intellectual, material, and technological resources provided by the U.S. military to Korean medical circumstances and the historical legacies of colonialism. The results of such analyses illuminate the intricate interplay between the U.S. military support and the Korean context of the Cold War, which had contributed to the development of the field of public health in South Korea.

Concurrent Medication Adherence in Hypertensive Patients With High-Risk Comorbidities.

Hypertensive patients with high-risk comorbidities require medications for each condition, leading to greater burden. The number of chronic conditions can affect patients' concurrent medication adherence. We aimed to compare the characteristics of groups based on their concurrent medication adherence and investigate the association between the number of high-risk comorbidities and concurrent medication adherence for patients with hypertension and high-risk comorbidities. A secondary data analysis was performed with the 2018 Korea Health Panel Survey, including 2230 patients with hypertension and at least 1 high-risk comorbidity who were prescribed medications for at least 2 conditions. Using medication adherence for each condition, we identified 3 concurrent medication adherence groups: adherent, suboptimal, and nonadherent groups. Multinominal logistic regression was used to determine the association between the number of high-risk comorbidities and the concurrent medication adherence groups. Adherent, suboptimal, and nonadherent groups included 85%, 11%, and 4% of the patients, respectively. Whereas having more high-risk comorbidities was associated with belonging to the suboptimal group compared with the adherent group (adjusted odds ratio, 1.46), having fewer high-risk comorbidities was associated with belonging to the nonadherent group compared with the adherent group (adjusted odds ratio, 0.52). We identified 3 groups based on their concurrent medication adherence. Our results indicated that the relationship of the number of high-risk comorbidities with the concurrent medication adherence group was inconsistent.

Exploring the interest of medical students in global health in South Korea: Does taking a global health course matter?

BackgroundPrioritizing global health is important for positive health outcomes. Doctors play a pivotal role in addressing health issues that they need to recognize the importance of global health practice. However, medical education in global health is still in its early stages in many countries, including South Korea.MethodsThis study is a quantitative cross-sectional study. Medical students were recruited from all 40 Korean medical schools and data collection was conducted in 2021. Stratified proportional quota sampling was employed as the sampling method. The study examined medical students’ interest in global health as the dependent variable. Independent variables included whether individuals had taken global health courses as part of their medical curriculum, while covariates included student background and institutional factors. Logistic regression was used to determine if taking a global health class was associated with global health interests.ResultsThe study included 2450 participants and almost 32% of medical students (n = 781) were interested in global health. Taking global health classes in school was associated with a higher likelihood of developing an interest in global health (OR: 1.29, 95% CI: 1.00-1.67). The likelihood of being interested in global health decreased across the academic year (OR: 0.70, 95% CI: 0.53–0.94). Individuals in graduate entry programs were associated with an interest in global health (OR: 1.32, 95% CI: 1.01–1.72).ConclusionThis study provides the first comprehensive nationwide assessment of medical students’ perspectives on global health education in South Korea. The findings underscore the importance of early and sustained exposure to global health topics in medical education in fostering interest in global health. These results can serve as valuable evidence for medical educators seeking to integrate global health education into their curricula.

Socioeconomic differences in the perception of inequalities in healthcare utilization and health in South Korea

This study investigated the lay perception of inequalities in society, healthcare utilization, and health in Korea. We also examined the association between socioeconomic status (SES) and perception of inequalities. Data from an online survey on the perception of health and healthcare inequalities related to cancer conducted between October 19, 2021, and November 12, 2021, were used. Data of 3,769 participants aged 20 to 74 years from 17 provinces were analyzed. We examined the perceived level of inequalities according to SES or residential area using frequency analysis, a t-test or analysis of variance (ANOVA), multiple linear regression analysis, and multiple logistic regression analysis. The mean score for perception of social inequality was 5.99 [Standard Deviation (SD) = 1.95] and that for perception of healthcare utilization inequality was 4.75 (SD = 1.96). The perception rate of health inequality according to SES and residential area was approximately 59 % and 61 %, respectively. Higher the income level, lower the level of perception of social inequalities β = -0.22, p < 0.01). Higher the education level, higher the level of perception of healthcare utilization inequalities (β = 0.21, p < 0.01). Higher the education level, higher the level of perception of health inequalities according to SES or residential area [adjusted odds ratio (aOR): 2.33 (95 % CI: 1.48, 3.66); aOR: 2.73 (95 % CI: 1.73, 4.31)]. Socioeconomic inequalities were observed in the perception of inequalities in healthcare utilization and health. Policymakers should establish policies to bridge the gap between perceived healthcare utilization inequalities and health inequalities. Future research should investigate the perception of healthcare utilization and health inequalities.

Education, Employment, Family Formation Behaviors, and the Gender Health Gap: A Cross-National Comparison of Korea, the United States, and Finland

Abstract Despite improvements in the social status of women in recent decades, women still tend to report lower levels of health compared to men. This study examines the role of individual factors (i.e., education, employment, and family formation behaviors) and aggregate factors (i.e., gender context, work cultures, and work-family policy) in the association between gender and health using the cases of Korea, the United States, and Finland. The study’s results indicate that women experience lower levels of health than men in Korea and the United States, especially among younger adults, even after accounting for education, employment, and family status. In Finland, however, women do not have lower levels of health than men. Moreover, among older individuals, Finnish women exhibit a health advantage relative to Finnish men. The findings indicate that traditional gender role expectations, long hours at work, and inadequate work-family balance largely account for gender disparities in health in Korea and the United States. Gender egalitarianism at work, reduced work hours, and more family friendly work policies should help reduce such disparities.

Identifying Critical Factors and Trends Leading to Fatal Accidents in Small-Scale Construction Sites in Korea

Small-scale construction sites in South Korea account for about 91.5% of all construction workplaces and contribute to 72.3% of the total accidents and fatalities. Safety measures at these sites are often underestimated, and proper safety education is lacking. In particular, the fatality rate is about 4.43 times higher compared to medium-/large-scale construction sites. In this study, a systematic analysis was conducted to examine the causes and trends of industrial accidents in small-scale construction sites to address these issues. This study analyzed industrial accidents in small-scale construction sites using statistical analysis, LDA topic modeling, and network analysis based on data from the Korea Occupational Safety and Health Agency (KOSHA) from 2018 to 2022. The analysis revealed that the most critical cause of accidents in small-scale construction sites is ‘Scaffolding and working platforms’, with accidents primarily involving ‘Fall’. Furthermore, various risk factors and accident trends were identified in apartment construction, new building projects, and mobile scaffolding usage. This study systematically analyzed the causes and trends of industrial accidents at small-scale construction sites, providing important evidence to enhance safety management and preventive measures. The results are expected to play a crucial role in establishing a safety culture at construction sites and ensuring the wellbeing of construction workers.

Real-time monitoring unsafe behaviors of portable multi-position ladder worker using deep learning based on vision data

Introduction: Fatal fall from height accidents, especially on construction sites, persist, underscoring the importance of monitoring and managing worker behaviors to enhance safety. Deep learning showed the possibility of substituting the manual work of safety managers. However, applying detection results to determine compliance with safety regulations has limitations. Method: This study estimated the actual working height depending on the height of the object detection bounding box by specifying the consistent hinge part as a target marker based on ladder manufacturing regulations. Furthermore, an attempt was made to improve the separation between workers, coworkers, and persons unconnected to ladder activities by applying an optimized loss function alongside an attention mechanism. Results: The experimental results showed that an average precision increased from 87.60% to 90.44%. The performance of the monitoring unsafe behavior of ladder worker following the Korea Occupational Safety and Health Agency (KOSHA) guide was evaluated by 91.40 F1-Score, which accumulated sorted according to the working height. Conclusions: Experimental results show the feasibility of the real-time automate safety monitoring in ladder work. Practical Applications: By linking the estimated working height and deep learning multi-detection results to established safety regulations, the proposed method shows the potential to automatically monitoring unsafe behaviors in construction site.

Factors Affecting the Life Satisfaction of School-Aged Children with Vietnamese Immigrant Mothers in Korea.

Low life satisfaction among multicultural children is an important issue related to children's mental health in Korea. The purpose of this study was to identify factors influencing the life satisfaction of children whose Vietnamese mothers migrated to Korea for marriage. Data from the Multicultural Adolescents Panel Study (MAPS) conducted by the National Youth Policy Institute (NYPI) in 2020 were used. The participants were 586 elementary school students. The mean age was 11.01 years (SD 0.19), and 52.0% were girls. Based on Engel's biopsychosocial (BPS) model, biological factors (gender, physical health, and body mass index), psychological factors (mental health, acculturative stress, self-esteem, and general stress), and sociocultural factors (family economic status, social support, and parenting style) were measured and analyzed by using hierarchical multiple regression. In the final model, self-esteem (β = 0.399, p < 0.001), parental social support (β = 0.184, p < 0.001), and neglectful parenting style (β = 0.085, p = 0.031) were positively related to children's life satisfaction, whereas general stress (β = -0.213, p < 0.001) and acculturative stress (β = -0.104, p = 0.002) were negatively related. The overall explanatory power was 41.7%. In conclusion, it is necessary to develop a specialized program that focuses on strengthening the bonds between parents and their children to enhance family functioning for multicultural families.
