The impact of expected child-rearing expenses on childbirth based on the matching of two Korean panel data

In Korea, recent upward trends in age of marriage and downward trends in fertility rates have motivated the Korean government to provide childbirth grants and Early Childhood Education and Care (ECEC) subsidies. Through such provisions, the government hopes to lower parents’ concerns regarding child-rearing expenses and to promote higher birth rates. Using combined data from the Panel Study of Korean Children (PSKC) and the Korea Longitudinal Study of Women and Families (KLoWF), this study analyzes the relationship between birth rates and anticipated child-rearing expenses. The method of kernel matching was used to combine and analyze information on children from the KLoWF and the child care environment as well as on child-rearing expenses from the PSKC. The study’s findings suggest a significant but weak relationship between birth rates and the anticipated financial costs for raising a child. This relationship is more prominent in the low-education and low-income group than in economically well-situated and highly educated families. Based on the results, we suggest the following policy recommendations: firstly, further research needs to be conducted to determine the effects of governmental support on child-rearing. Secondly, customized support that considers family income and education should be provided to improve birth rates.

Pathways from mothers' early social support to children's language development at age 3

AbstractThe relationships between early maternal social support, maternal psychological well‐being, the home learning environment, and children's language skills at age 3 in Korean families were examined. We hypothesized that maternal social support would predict children's language development through its effect on maternal psychological well‐being and the home learning environment. Structural equation modeling was employed to analyze the conceptual model, using data collected from 1,725 Korean families who participated in the Panel Study of Korean Children. Mothers' early social support predicted children's language skills via 2 indirect paths. First, greater social support predicted more positively adjusted psychological well‐being; maternal psychological well‐being was significantly associated with the quality of the home learning environment, which in turn predicted the positive development of language skills in children. Second, greater social support predicted a better home learning environment; again, the home learning environment positively predicted children's linguistic development. The direct paths from social support to language development were not significant. Social support during the child's infancy was observed to be beneficial for stimulating the home learning environment later. A comparison between working mothers versus nonworking mothers yielded no significant differences in the relationships between the variables. The results shed light on the importance of sensitive measures of social support in order to better understand its beneficial effects on mothers and young children.Highlights The relationships between early maternal social support, maternal psychological well‐being, the home learning environment, and children's language skills at age 3 in Korean families were examined.

Rate of humidifier and humidifier disinfectant usage in Korean children: A nationwide epidemiologic study

In South Korea, a cluster of humidifier disinfectant-induced lung injury (HDLI) cases developed between 2006 and 2011. There are no existing reports regarding the rate of humidifier disinfectant (HD) usage in the general population of Korean children. The purpose of this study was to investigate the rate of humidifier and HD usage in the general population of Korean children. This is a general population-based birth cohort multicenter study, Panel Study of Korean Children (PSKC) from 2008, a humidifier and HD-related questionnaire administered to 1577 subjects (809 male, 768 female) in 2015 (n=1577). The questionnaire consisted of four categories (humidifier usage, HD usage, exposure duration, and type of HD brands). A total of 75.6% (1192/1577) had used a humidifier, and the rate of HD usage was found to be 31.1% (409/1316). Polyhexamethylene guanidine (PHMG), used as a disinfectant, was found to have the highest usage rate (62.0%). HD was used for less than 3 months of the entire lifetime of most of the subjects. In conclusion, approximately 30% of young Korean children were exposed to HD. PHMG-containing HD was the most commonly used. These results suggest that a nationwide epidemiologic investigation is needed urgently, and children exposed to HD should be investigated regarding their status of lung injury, including a pulmonary function test. Moreover, a long-term follow-up period may be required to evaluate HD usage-associated lung injury.

A Short-Term Longitudinal Study on the Reciprocal Relations between Mothers’ Depression and Their Preschoolers’ Emotional Problems

This study examined the causal relationship between a mothers’ depression and the emotional problems of their preschool-aged children as indicated by anxiety, depression and emotional reactivity. We analyzed data from 1,528 mothers and their children from the Panel Study of Korean Children (PSKC) collected when the children were 4 years old and 5 years old. Autoregressive cross-lagged modeling was conducted using AMOS ver. 23.0 to investigate the longitudinal reciprocal effects between mothers’ depression and children’s emotional problems. The results indicated that both mothers’ depression and children’s emotional problems were relatively stable between the ages of 4 to 5. There were significant cross-lagged effects from the mothers’ depression to children’s emotional problems and from children’s emotional problems to mothers’ depression. Mothers reported higher levels of depression when the children were 4 years old and the children showed more anxiety, depression and emotional reactivity when they were 5 years old. Emotional problems when the children were 4 predicted greater depression among mothers 1 year later. We also examined the group difference (between boys and girls) in the study model. Gender differences were not statistically supported. The results suggested that early assessment and intervention for mothers’ depression and children’s emotional problems are essential for a healthy mother-child relationship and later child outcomes. Keywords: maternal depression, preschooler, emotional problem, autoregressive cross-lagged modeling

생애 초기 보육경험과 만 4세 유아의 사회정서발달 간 관계

The present study aimed at investigating the relations between the amount of child care experienced in the first three years of life and socioemotional development of children at age 4 indicated by problem behaviors and peer competence. Using the longitudinal data of the Panel Study of Korean Children(PSKC), the information of 1,699 children were analyzed. The results indicated that any child care experience, hours in child care, full-time child care and early entry to child care were significantly related to children's externalizing behavior problem and play disruption at age 4. Some significant relations were detected between child care experience and better peer competence as well. Interestingly, the patterns of relations were different for boys and girls. Being in child care, a greater amount of child care and early entry to child care tended to be related to externalizing problem behaviors of boys and whereas they were more related to peer competence of girls indicated by play interaction, play disruption and play disconnection. Child care hours at age 3 were relative stronger predictors of children's development compared to those at age 1 or at age 2. The findings imply that the amount of child care during the first 3 years of life does not have strong harmful effects on preschoolers' socioemotional development and that there are differences in the effects of child care on boys and girls.

Trajectories of Maternal Depressive Symptoms and Behavioral Problems of Children at Four Years of Age: Evidence from the Panel Study of Korean Children

The present study identifies trajectories of maternal depressive symptoms in Korean contexts and explores their associations with children’s behavioral problems at four years of age. Using the Panel Study of Korean Children, depressive symptoms of 1,964 mothers were collected at five time points (right after childbirth at hospitals, one month postpartum, four months postpartum, 24 months postpartum, and 48 months postpartum). These data were analyzed using latent class growth analysis. Korean mothers’ depressive symptoms from childbirth to 48 months postpartum were best described by five trajectories: No Symptoms (30.8 %), Low Symptoms (46.8 %), Increasing Symptoms (9.2 %), Persistent Moderate Symptoms (8.8 %), and High Symptoms (4.3 %). In addition, trajectories of depressive symptoms of Korean mothers were found to have meaningful associations with their children’s behavioral problems at four years of age. However, the complex results of the present study provided no clear answers regarding how chronicity, severity, and timing of maternal depressive symptoms associate with young children’s behavioral problems.

Preschoolers’ Language Ability, Cognitive Ability, and Peer Relationships by Creative Thinking Group

Objective: This study explored the creative thinking styles of children according to cluster analyses and examined group differences in language ability, cognitive ability, and peer relationships. Methods: The study used the data from the 2012 Panel Study of Korean Children by the Korea Institute of Child Care and Education. The participants comprised 1,681 4-year-olds. Data were analyzed via cluster analyses, χ2 distributions, and ANOVA tests. Results and Conclusion: The results from the cluster analyses based on percentiles of the sub-factors of K-FCTYC (Korean Figural Creativity Test for Young Children) indicated four clusters: “divergent creative with openness,” “non-creative,” “divergent creative,” and “multiple creative.” Additionally, the four clusters differed by gender, language ability, cognitive ability, and peer relationships. Keywords: creativity, cluster analysis, gender difference, language ability, cognitive ability, peer relationships

Clusters of Preschoolers' Play Behaviors

Objective: This study aimed to examine the predictors of indoor play behaviors using cluster analyses. Methods: Data from 963 children (age 4 years) who participated in the 5th phase of the Panel Study of Korean Children, their parents, and their teachers were analyzed using K-means clustering analyses, F-tests and multinomial logistic regression analyses. Results: The clustering analyses revealed three distinctive profiles: positive-theme oriented, general-exploratory/manipulative, and negative-exploratory/manipulative groups. Child characteristics, including cognition, language, and social level, and teachers’ age were significantly associated with the groups in a different way; the clusters were partially different in the gender and creativity of children, interaction level of teachers' interaction, classroom environment, and program types that children attended. Conclusion: Findings revealed three clusters of play behaviors and highlighted the importance of the ecological variables that determined the clusters. Keywords: indoor play behaviors, peer play interactions, preferred interest areas

The Effect of Infancy Childcare Center Use and Maternal Employment on Toddlers’ Language Development in South Korea

Using first to fourth wave data of the Panel Study of Korean Children (PSKC), this study explores the effects of childcare center use, maternal employment, and other child and familial characteristics on the language development of toddlers in Korea. Among the 2078 families with children in the PSKC, those who completed the Receptive and Expressive Vocabulary Test at the fourth wave were selected, and a small number of disabled or prematurely born children were excluded. In addition, to clarify the effects of maternal employment, families with mothers who were either employed or unemployed for three consecutive years during the child's infancy were selected. Regression analysis showed that neither childcare center use nor maternal employment during infancy had significant effects on toddlers’ expressive and receptive vocabulary at the fourth wave. Family characteristics, such as household poverty and maternal education level, as well as child characteristics, such as gender and birth order, had significant effects on expressed vocabulary. However, only children's gender significantly affected the receptive vocabulary level of toddlers.

Marital satisfaction and maternal depressive symptoms among Korean mothers transitioning to parenthood.

Although many empirical findings support associations between marital satisfaction and depressive symptoms, gaps remain in our understanding of the magnitude and direction of the associations between marital satisfaction and depressive symptoms as well as the associations in a collectivistic culture. The present study examined autoregressive cross-lagged associations between marital satisfaction and maternal depressive symptoms across a 3-year investigation in a sample of Korean mothers transitioning to parenthood. The sample consisted of 2,078 mothers in the Panel Study of Korean Children. The mothers reported marital satisfaction and maternal depressive symptoms annually for 3 years. The results of an autoregressive cross-lagged model revealed bidirectional associations between marital satisfaction and maternal depressive symptoms. The findings provide evidence of an interactional model of depression in a sample of Korean mothers. (PsycINFO Database Record

유아기 자녀를 둔 아버지의 양육스트레스 영향 요인에 관한 연구

This study aimed to develop a model to explain the factors influencing father's parenting stress, and to verify the appropriateness of the model. The participants included 1609 fathers with a 5-year old. The study used 2012 Panel Study of Korean Children (PSKC) by the Korea Institute of Child Care and Education (KICCE), and analyzed with SPSS and AMOS programs. The analysis showed that first, father's income and parental efficacy were negatively related with parenting stress and father's depression and marital conflict were positively related with parenting stress. Second, father's parenting stress was directly and indirectly impacted by parental efficacy and their child's temperament. These results suggest that father education are needed for promoting positive paternal mental health and parental efficacy, to reduce parenting stress of fathers.

영아 어머니의 결혼만족도와 양육실제 관계에서 미치는 자아존중감의 매개효과와 소득수준의 조절효과

본 연구는 영아 어머니의 결혼만족도와 양육실제 간의 관계에 자아존중감이 매개하는지를 살펴보고, 이의 가구 소득 수준에 따른 매개효과가 차이가 있는지를 확인하고자 하였다. 이를 위해 육아정책연구소에서 매년 수집하는 한국아동패널 데이터 중 2010년 수집된 총 1,802명의 3차 연도 자료를 활용하였다. 이때 아동의 연령은 만 25.75개월(SD=1.37)이다. 본 연구는 선행연구에서 어머니의 양육행동에 직 간접적으로 영향을 미친다고 밝혀진 결혼만족도가 자아존중감을 통해 양육실제에 정적인 영향을 줄 것으로 예측하여 연구모형을 구성하였다. 구조방정식 모형을 사용하였으며, 데이터 분석 결과는 첫째, 어머니의 결혼만족도가 높을수록 긍정적인 양육행동에 직접적인 영향을 미칠 뿐 아니라 어머니의 자아존중감을 통해 간접적으로도 영향을 미치는 것으로 나타났다. 둘째, 가구 소득 수준에 따른 조절효과는 어머니의 결혼만족도가 자기존중감에 미치는 영향에서만 유의한 결과를 보였다. 이 연구 결과는 가구 소득 수준에 관계없이 어머니의 자아존중감 향상이 양육의 질을 높이는데 기여함을 시사한다. This study examines if self-esteem mediates the relationship between marital satisfaction and parenting practice by using the Panel Study of Korean Children of Korea Institute of Child Care and Education, and empirically analyzes if household income causes the difference of mediating effect. For this research, the 3rd Panel Study of Korean Children (2010), including 1,802 children whose average age is 25.75 months (SD=1.37), is employed. Based on the preceding studies which demonstrated the effect of marital satisfaction on mothers' parenting behavior directly and indirectly, a research model is designed by predicting that marital satisfaction might have a positive effect on parenting practice through the mediation of self-esteem. Structuring equation was used to analyze the model as the appropriate research method. The result of the data analysis utilizing a structural equation model is as follows: Firstly, the higher the marital satisfaction of a mother is, the more it influences her positive child-rearing attitude, not only directly, but also indirectly through her self-worth. Secondly, the modifying effect in accordance with the level of the income of a household was found to be meaningful only in the influences of the marital satisfaction to the self-worth. This study result suggests that the enhancement of the self-worth of a mother will contribute to improving the quality of child-rearing, regardless of the level of the income of a household.

어머니의 취업여부에 따른 양육스트레스와 자기효능감 간의 인과적 종단관계 분석

ABSTRACT This study examined the causal relationships between parenting stress and self-efficacy of Korean mothers with an infant according to employment status using the second through fourth wave data of the Panel Study of Korean Children (PSKC). Autoregressive cross-lagged modeling was performed to test the longitudinal reciprocal relationships between the two constructs. Our results indicated that both maternal parenting stress and self-efficacy were consistent over time. The results also indicated that there was a significant cross-lagged effect of maternal parenting stress on their self-efficacy, rather than vice versa. No differences between working and non-working mothers were found in the relationship between the two constructs.Keywords：어머니의 양육스트레스 (maternal parenting stress), 어머니의 자기효능감(maternal self-efficacy), 어머니의 취업여부(maternal employment status), 자기회귀 교차지연 모형(autoregressive cross-lagged modeling).

기혼여성의 취업 여부에 따른 둘째자녀 출산의도: 아버지의 양육참여를 중심으로

The purpose of this study was to find pathways among factors that distinguish the mothers' intention to have a second child. As for factors affecting the childbirth intention of mothers, this study aimed to explore pathways from fathers' participation in childrearing to intention of second childbirth as mediating variables, maternal parenting stress and marital satisfaction. This study used the third wave data of the Panel Study of Korean Children (PSKC) that is a national-representative birth-cohort study. Among the 1,802 participants of the PSKC, 717 mothers who have a husband/partner and only one child have responded a decided intention of second childbirth. SPSS 19.0 and Amos 19.0 were used to implement exploratory analyses of predictors and test path models. Results showed that the hypothetical model assuming a path from paternal involvement in childrearing to mothers' intention of second childbirth, mediated by maternal parenting stress and marital satisfaction fitted the data of working mothers and non-working mothers well. The results suggest policies focusing on internal characteristics of mothers and dynamics in the family.

The use of child care center for infants of dual-working families in Korea

Using the first and second wave data of the Panel Study of Korean Children (PSKC), which is comprehensive longitudinal data with a nationally representative birth cohort, this study explores whether and when dual-working families place their infants and toddlers in child care centers and what factors influence these families' selection process. Among the 2078 families examined in the PSKC, 466 dual-working families which had any kind of nonparental care arrangement for their very young children at the time of the second survey were included in the analysis. Since our research questions address when the use of child care centers occurred, an event history analysis was conducted. The results show that 32.4% of the families had placed their infants in child care centers prior to the second interview. Family structure and income variables (number of children, nonparental adults in the household, and household income), mother's education level, and the mother's number of working hours turned out to be significantly related to the probability of child care center use.

아버지의 자녀양육참여와 사회적 지원이 후속출산계획에 미치는 영향：어머니의 양육스트레스 매개를 중심으로

This study examined the effects of paternal participation in child care and social support on planning for a second childbirth, focusing on the mediating effect of the mother`s parenting stress. The 887 subjects studied in this paper were mothers who have a first child, and were selected from a sample of the 2nd Panel Study of Korean Children(PSKC) by the Korea Institute of Child Care and Education(KICCE), conducted in 2009. Data was analyzed using a Structural Equation Model(SEM) to identify a structure and relationships among factors. The significance of indirect effects to test the mediating effect of maternal parenting stress was identified via bootstrapping. Results indicated that maternal parenting stress partially mediated the relationship between the father`s participation in child care and planning for a second childbirth, and absolutely mediated the relationship between social support and planning for a second childbirth. The findings reveal the importance of reducing parenting stress, given its substantial impact on planning for a second childbirth.

영아 자녀를 둔 어머니가 지각하는 부의 양육참여와 산후 우울의 관계 : 부부관계의 매개효과 및 모의 자아인식의 중재효과

This study examined the mediating effects of marital relationships (marital satisfaction, marital conflict) and the moderating effects of mother`s self-perception (self-efficacy, self-esteem) on the relationship between a father`s involvement in parental roles and postpartum depression. The participants consisted of 1,863 mothers with infants from the Panel Study of Korean Children. The findings from this study are as follows. First, there were significant correlations between a father`s involvement in the parental role, marital satisfaction, marital conflict, self-efficacy, self-esteem and postpartum depression. Second, the relationship between a father`s involvement in the parental role and postpartum depression was significantly mediated by both marital satisfaction and marital conflict. Finally, both self-efficacy and self-esteem were seen to moderate the relationship between a father`s involvement in the parental role and postpartum depression.
