This longitudinal study investigated developmental changes in temperament and examined social adjustment problems by early temperamental characteristics and developmental patterns of temperamental change during infancy. Subjects were 153 six-month-old infants and their mothers. Infant temperament and toddler's problem behavior were measured by the Infant Behavior Questionnaire-Revised (Garstein & Rothbart, 2003) and the Toddler Behavior Checklist (Larzelere et al., 1989), respectively. Results showed that distress to limitations, high pleasure, perceptual sensitivity, and approach increased with age, while activity level, cuddliness, and vocal reactivity decreased. Infants with high scores in activity level, fear, sadness, and approach at 6 months showed more problem behaviors at 18 months. Infants showing abrupt developmental change of high pleasure and perceptual sensitivity developed more negative behavior.

The purpose of this research was to identify the importance of emotional development in early childhood, in children ages three to five, by examining the relationship between the variables in the children such as gender, age, and temperament, as well as their mothers' emotionality, in relation to emotional development. The participants included a total of 72 children between three and five years of age. The major findings are as follow: First, there were significant differences in emotional expression and emotional recognition between the boys and the girls. Additionally, the emotional recognition of the children increased as age increased, and more positive strategies for emotional regulation were used with the increasing age of the children. Temperament characteristics did not have any relationship with emotional expression or emotional recognition, while the strategies for emotional regulation were related to the temperament characteristics. Second, the emotional expressivity of the mother was related to the emotional expression and recognition of the child, but wes not associated with strategies for emotional regulation. The emotional reactivity of the mother was related to a child's strategies for emotional regulation, but not to emotional expression or recognition. Third, emotional development of the children wes influenced by the individual child variables and emotionality of the mother.

The purpose of this study is to investigate the variables that affect the problem behavior of children and to examine the relationships between problem behavior of young children in relation to the child's characteristics(temperament and ego-resiliency), the mother's characteristics(parenting stress and personality characteristics), and the teacher's characteristics(teacher-child relationship and emotional expressiveness). The researcher surveyed 314 parents and 56 teachers of young children in the transitional period from 32 early childhood institutes in Daejeon. The summaries of the results of the study are as seen below. First, the child's gender and mother's education were statistically significant variables in explaining the variance in problem behavior of young children. More boys than girls showed more problem behaviors and children of mothers who graduated university showed less problem behavior. Second, teacher-child relationship was the most predictive variable in problem behavior of young children. Children who had good relationships with their teachers showed less problem behavior and children who had poor relationships with their teachers showed more problem behavior. The results of this study can provide basic data for consulting and developing program to prevent and treat the problem behavior of young children to consider the development of children.

Objectives The objective of this study was to investigate the differences in sociodemographic and clinical characteristics, temperaments, and quality of life between panic disorder (PD) patients with and without major depressive disorder (PD+MDD and PD-MDD patients, respectively). Methods We compared 411 PD-MDD and 219 PD+MDD patients. All patients who were drug-free for at least 1 month were assessed at initial outpatient visits before the administration of medication. The following instruments were used for assessment: the NEO Personality Inventory-Neuroticism (NEO-N) ; the Temperament and Character Inventory-Harm Avoidance (TCI-HA) ; the State-Trait Anxiety Inventory (STAI) ; the Intolerance of Uncertainty Scale-Short (IUS); the Anxiety Sensitivity Index-Revised (ASI-R); the Beck Depression Inventory (BDI) ; the Beck Anxiety Inventory (BAI); the Penn State Worry Questionnaire (PSWQ) ; the Generalized Anxiety Disorder for 7 item (GAD-7) ; the Albany Panic and Phobia Questionnaire (APPQ) ; the Panic Disorder Severity Scale (PDSS) ; the Early Trauma Inventory Self Report-Short Form (ETISR-SF) ; the Scale for Suicidal Ideation (SSI) ; the World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF) ; the Sheehan Disability Scale (SDS) ; and the Short Form health survey (SF-36). Results Compared to the PD-MDD patients, the PD+MDD patients were younger and more likely to be unmarried. They showed higher rates of unemployment, lower levels of education and income, younger age of onset, more previous suicide attempts, a greater incidence of agoraphobia, and more previous treatments. The PD+MDD patients showed significantly higher scores on the NEO-N, the TCI-HA, the STAI, the IUS, the ASI-R, the BDI, the BAI, the PSWQ, the GAD-7, the APPQ, the PDSS, the ETISR-SF, and the SSI. In addition, the PD+MDD patients showed significantly lower quality of life than did the PD-MDD patients. In contrast with previous studies, we observed no significant differences between the two groups in terms of gender, duration until treatment, and psychiatric comorbidities. Conclusions This study showed that the PD+MDD patients have more early trauma experiences, higher levels of anxiety-related temperaments, more severe panic and depressive symptoms, and lower quality of life than the PD-MDD patients.

The purpose of this study was to examine the specific nature of early relationship between infant and father. The subject pool for the study consisted of 42 middle-class infant-father days. Infant's ages were 12 moths to 17 months. All were fullterm babies In order to assess the patterns of infant-father attachment each dyad was videotaped in the simulated Strange Situation of Ainsworth et al(1978). In order to assess the paternal sensiti-vity toward the infant's cue,. each dyad was also filmed for a 3-minute Questionnaire Situation Gratification of the Transition to Fatherhood. Also at home mothers completed a report on infant temperament using the Infant Characteristics Questionnaire. Among 42 infants 48% or 20 were classified as securely attached 38% or 16 as anxious-avoi-dant and 14% or 6 as anxious-resistant Using the discriminant function coefficients for combi-ning the paternal sensitivity scores 83% of the infants were correctly classified as A. B. C The patterns of attachment were not found to be significantly different in the paternal childhood experience for attachment relationship to his own parents. Degree of Difficulty and Gratification groups with respect to infant temperamental fussiness.

The purpose of this study was to investigate the role of variables on young children's external aggression and relational aggression. Specifically, young children's temperaments and gender differences, parental marital conflicts, fathers' anti-social behaviors, mothers' child-rearing behaviors and psychological characteristics were studied. The findings of the study were as follows: Firstly, it was found that male children exhibited a higher level of external aggression than female children, while there was no significant difference between male and female children in terms of relational aggression. Secondly, analysis of variables such as children's temperaments and domestic environments revealed that fathers' anti-social behaviors, the adaptability of young children's temperaments and mothers' depression tendency have significant explanatory adequacies for young children's relational aggression. Furthermore, gender difference adaptability, activity and emotionality of young children's temperaments, in addition to parental marital conflicts, also have significant explanatory adequacies for young children's external aggression.

The purpose of this study was to find out the current status of smart phone usage, differences of developmental characteristics and time diaries between high- and low- usage groups. The study also tried predicting variables among children's personal and family environment factors in order to classify four year old children in the fifth year Panel Study on Korean Children into the two groups. Data was collected from 435 smart phone users and 157 of them who had started to use a phone before age 3.Frequency analysis, t-test and logistic regression were performed. The results showed that most 4 year old children started to use a phone in their fourth year and used it frequently. The low level groups of girls and all participants showed lower levels of behavior problems, and the low level group of all participants had a longer sleep times than the high level group had. Children's activity and social temperament were identified as predicting variables for classifying children into the two groups. The results suggested the necessity of measures preventing children from excessive smart phone usage in their early years and to consider children's temperament first.

Objective: The purpose of this study was to examine underlying types of developmental trajectories of adaptation to child care among infants and toddlers. This study also aimed to identify latent classes in their child care adaptation types in order to find predictors that account for individual differences. Methods: Participants were 420 mothers of infants and toddlers and 123 teachers. The levels of child care adaptation of participating infants and toddlers were rated monthly from early April to June, 2019. The collected data were analyzed using growth mixture modeling, latent class analysis and multinominal logistic analysis. Results: The results of growth trajectories of child care adaptation showed there were two to four latent groups by dimension of child care adaptation. Also, the groups of individual dimensions of child care adaptation were classified into three latent classes, which were 'complying and positive group', 'negative group', and 'individualized group. Multinominal logistic analysis revealed that children's age, gender, and temperament differentiated the three latent classes of adaptation to child care. Conclusion/Implications: The results show individual characteristics that infants and toddlers possess should be prudently considered in order for successful adaptation to child care.
