The purpose of this study was to identify developmental trajectories of externalizing problems in preschoolers and to investigate dimensions of temperament and parental behaviors associated with trajectory groups. Subjects were 180 3- to 5-year-old preschoolers (96 males, 84 females) in the metropolitan area of Seoul. They were assessed three times at 5 month intervals over a one year period. Teachers reported on children's behavior problems, and parents reported on children's temperaments. Latent Growth Curve Modeling Analysis with cohort sequential design revealed externalizing behaviors gradually decreased between 3 and 6. At the 6-year-old level externalizing behaviors were associated with high novelty seeking temperament. The results were discussed in terms of the importance of longitudinal research in developmental psychopathology.

The purpose of this research was to analyze the trajectory of child's academic attainment and the effect of family socioeconomic background on the trajectory. Data were part of the Korea Youth Panel Survey 2003-2005(Middle School 2) and were analyzed by Latent Growth Curve Modeling(LGM). The degree of child's academic attainment decreased over 3 years. Socioeconomic status variables that influenced academic trajectory were family poverty, parent's attainments in scholarship, and family structure. Findings from this study suggest that societal support for low socioeconomic status families is needed for improvement of academic attainment of their children.

The purpose of this study was to employ the Latent Growth Curve Model to investigate the developmental trajectories of maternal depressive symptoms and to identify predictors that might have an effect on change and the level of developmental trajectories. The results of this study indicated that the maternal depressive levels of a high risk group had increased significantly over the past 5 years. The predictors for these developmental trajectories of maternal depressive symptoms were as follows; birth order, maternal prenatal depressive levels, self-esteem, marital satisfaction, parenting stress and the level of family crisis experienced by the high risk group.

The Special Needs Education Assessment Tool (SNEAT) were verified of reliability and validity. However, the reliability and validity has been verified is only Okinawa Prefecture, the national data has not been analyzed. Therefore, this study aimed to verify the reliability and construct validity of SNEAT in Miyagi Prefecture as part of the national survey. SNEAT using 55 children collected from the classes on independent activities of daily living for children with disabilities in Miyagi Prefecture between November and December 2015. Survey data were collected in a longitudinal prospective cohort study. The reliability of SNEAT was verified via the internal consistency method; the coefficient of Cronbach's ${\alpha}$ were over 0.7. The validity of SNEAT was also verified via the latent growth curve model. SNEAT is valid based on its goodness-of-fit values obtained using the latent growth curve model, where the values of comparative fit index (0.997), tucker-lewis index (0.996) and root mean square error of approximation (0.025) were within the goodness-of-fit range. These results indicate that SNEAT has high reliability and construct validity.

Objectives: While epidemiologic research indicates that the prevalence of risk-taking behaviors including cigarette smoking among young people with asthma is substantial, the longitudinal patterns of cigarette smoking in this vulnerable population have received little attention. The aim of this study was to evaluate differences in the longitudinal trajectories of cigarette use behaviors from adolescence to adulthood between young people with and without asthma. Methods: Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) during the years 1994 to 1995 (Wave I, adolescence), 2001 to 2002 (Wave III, young adulthood), and 2007 to 2008 (Wave IV, adulthood) were analyzed (n=12 244). Latent growth curve models were used to examine the longitudinal trajectories of cigarette use behaviors during the transition to adulthood according to asthma status. Results: Regardless of asthma status, the trajectory means of cigarette use behaviors were found to increase, and then slightly decrease from adolescence to adulthood. In total participants, there were no statistically significant differences in initial levels and changes in cigarette use behaviors according to asthma status. However, in select sex and race subgroups (i.e., females and non-whites), former asthmatics showed greater escalation in cigarette use behaviors than did non-asthmatics or current asthmatics. Conclusions: This study indicated that the changing patterns of cigarette use behaviors during the transition to adulthood among young people with asthma are comparable to or even more drastic than those among young people without asthma.

정부는 대학 연구비 지원에 기반하여, 기술사업화 정책을 추진해 왔다. 본 논문에서는 신제도주의 이론을 바탕으로 정부의 연구비 지원의 변화율이 기술사업화 성과의 변화율에 미치는 영향과 대학 소재지에 의한 조절효과를 분석하였다. 시간적 변화 분석에 통용되는 잠재성장곡선모형(Latent Growth Curve Model, 이하 LGM)을 활용하여, 2009년~2017년 9년 간 전국 4년제 138개 대학의 데이터를 분석하였다. 그 결과 정부지원 연구비의 증가율은 기술이전 수입료 증가율에 정(+)의 영향을 미치며, 비수도권 대학보다 수도권 대학에 더 큰 영향을 미친다는 것을 확인하였다. 이러한 관계는 시간 지연효과를 고려한 분석에서도 동일하다는 것을 확인하였다. 이를 바탕으로 대학의 기술사업화를 촉진하기 위한 정부의 연구비 지원 정책의 효과성에 대해서 대학의 소재지에 따라 차별적 이해가 필요함을 강조하였다.

Objectives: This study aimed to estimate the trajectory of depressive symptoms among aged 20 years adults and examine the direct and indirect pathway linking socioeconomic status(education attainment, household income, occupation), alcohol use and depressive symptoms. It particularly focused on whether alcohol use would mediate the relationship between socioeconomic status and depressive symptoms. Methods: This study analysed 13,763 households of Korean Welfare Panel Study 1st, 2nd, 3rd data using Latent Growth Curve Modeling. Results: The results showed that study participants tend to decrease depressive symptoms with years. Similar to the findings of the previous studies, education attainment and household income among the socioeconomic status factors effected directly depressive symptoms and indirectly by mediating alcohol volume controlling sex and age. Conclusions: Based on findings of this study, the policy and practical implications were discussed.

The purpose of this study was to investigate trajectories of relational aggression in preschool children. The latent growth curve model was used to examine relational aggression in 3 to 5 year olds. The participants were 3-year-old children recruited from preschools and daycare centers. The children's verbal ability was assessed by interview and teachers completed measurements of negative emotionality and relational aggression. The findings suggest that relational aggression decreased during the preschool years. Gender, language ability, and negative emotionality showed positive effects on the initial level of relational aggression. Moreover, gender and negative emotionality had negative effects, however, language ability had positive effects on the change rate of relational aggression.

Purpose: The aim of this study was to examine the correlation between school-life adjustment and suicidal ideation in adolescents by applying the latent growth curve models to the longitudinal data. Methods: This study analyzed three waves of data from the Korean Children & Youth Panel Survey (2014~2016). A total of 1,534 students were included in the analysis. In the application of the latent growth curve models to the longitudinal survey data, we analyzed the initial status and growth changes for each wave, identified individual differences in the general characteristics, and examined the direct relationship between the two latent constructs. Results: The analysis revealed that variations in the initial status and rate of school-life adjustment were significant with respect to parents' education level, household income and academic satisfaction. Variations in the initial status and growth rate of suicidal ideation were significantly associated with household income and family structure. The relationship between school-life adjustment and suicidal ideation showed a negative correlation in which the starting value of the former increased and that of the latter decreased and vice versa. Conclusion: The results confirmed that school-life adjustment and suicidal ideation varied according to students' general characteristics. In addition, school-life adjustment was negatively correlated with suicidal ideation, thereby highlighting students' ability to adjust as an important factor influencing their suicidal thinking.
