The purpose of this study was to investigate the temperament characteristics associated with stuttering subtypes (persistent and recovered) over time and the relationship between those characteristics and stuttering severity. This four-year longitudinal study covered 41 preschool children who stutter (CWS) and 30 preschool children who do not stutter (the CWNS group). At the final visit, 27 CWS were classified as the Recovered group and 14 CWS were classified as the Persistent group. Using the Children's Behavior Questionnaire-Short Form, each participant's temperament characteristics were measured twice: at one year and two years after the initial visit. The three subscale scores (Extraversion, Negative Affectivity, and Effortful Control) and the 15 component scores were analyzed, and they were used for between-group and between-visit comparisons. The Persistent group showed a significantly higher Negative Affectivity subscale score at every visit than the Recovered and CWNS groups. Within this subscale, significant group differences were found in the 'Fear' and 'Anger/Frustration' components, demonstrating that the Persistent group scored higher than the Recovered and CWNS groups. There was no significant correlation between the subscale and component scores and the stuttering severity scores within the Persistent group at any visit. These results support the proposition that these two stuttering subtypes have different temperament characteristics; they also imply that temperament might be influenced by stuttering experience over time.

Objectives：This study was designed to investigate the temperamental characteristics and the differences of temperamental characteristics in Korean children according to the sociodemographic and family environment factors using Toddler Temperament Scale(TTS). Methods：The samples consisted of 1,175 children who were attending twenty-five Samsung Child Care Centers nationwide. Both Korean version of TTS and child developmental questionnaire(designed by the Department of Psychiatry, Samsung Medical Center) were distributed to the parents of these children. Score of 9 temperamental categories was determined using the result of TTS, and determination of 5 temperamental clusters was conducted by the Fullard's criteria. Statistical analyses were performed according to the sex, birth order, existence of siblings, residential city, residential province, marital state of child's parents, and parental relationship to compare the scores of temperamental categories and the distribution of temperamental clusters. Results：The distribution of temperamental clusters was as follows；Easy 35.8%, Intermediate Low (IL) 33.1%, Intermediate High(IH) 11.1%, Slow-To-Warm-Up 6.3%, and Difficult 13.6%. Some of 9 temperamental categories were statistically different according to the sex, birth order, existence of siblings, residential city, residental province, marital state of child's parents, and parental relationship. From the viewpoint of 5 temperamental clusters, there were statistically more Easy and less Difficult children in good relation between each parent(p=.022). In spite of no statistical significance, the children in conditions of first-born, non-existence of siblings, middle or small residential city, Chung-Cheong province, married state of parent had a tendency to be easier to care. Conclusions：The toddler temperamental characteristics of Korean children showed some differences in several sociodemographic and family environment factors. We could confirm that the 'Goodness of Fit' was very important in child temperament.

Objectives：One of the most common developmental problems is communication disorder in which a child appears normal in every way but who has failed to begin speaking or speaks very little. A few studies have examined the temperamental characteristics of children with communication disorders. This study was to investigate the temperamental characteristics of Korean children with communication disorders. Methods：The parents of 20 Korean children with communication disorders and the parents of 50 normal control children, the age of both groups ranges from 3 to 7, completed Korean version of Parental Temperamental Questionnaire developed by Thomas and Chess. Children with a pervasive developmental disorder, mental retardation, or speech-motor or sensory deficit were excluded. The scores of each temperamental scale of two groups and the diagnostic clusters of two groups were compared. Results：The children with communication disorders were characterized by lower mood scores and higher intensity of reaction scores than normal controls. The two groups showed no significant correlation in terms of the temperamental diagnostic clusters. Conclusion：This findings suggest the existence of a distinct temperamental profile of the children with communication disorders. Early detection of the profile may be of great value for parents in understanding the developmental characteristics of the children with communication disorders and in providing appropriate parenting approaches.

The objective of this study was to compare the family environment and developmental history of three groups of children classified by their temperament. The parents of 484 Korean children aged between 3 and 7 years completed the Korean version of Parental Temperamental Questionnaire developed by Thomas and Chess and Developmental Questionnaire created by Division of Child and Adolescent Psychiatry, Samsung Medical Center. After clustering these children into 5 temperamental groups according to the method proposed by Fullard et al, 98 Easy, 36 Difficult, and 21 Slow-To-Warm-Up children were included in the analysis. Statistically meaningful differences observed among three groups were as follow：1) Marital conflict of parents was more frequent in Difficult and Slow-To-Warm-Up children than in Easy children. 2) Parentchild conflict was more frequent in Difficult children than in Easy children. 3) Conflict among siblings was more frequent in Difficult children than in Easy children. 4) Average monthly income of family was less in Difficult children than in Easy children. 5) Toilet training was achieved later in Difficult children than in Easy children. 6) Motor development was slower, between 2 and 5 years old, in Slow-To-Warm-Up children than in Easy children. 7) Fear of stranger started earlier in Slow-To-Warm-Up children than in easy children. 8) Physical health was poorer in Difficult and Slow-To-Warm-Up children than in easy children. The findings indicate that Difficult child or Slow-To-Warm-Up child group have unfavorable family environment, different developmental milestone and poorer physical health in comparison with Easy child group.

This study was designed to explore whether the temperament of a child influences the physical growth. The Korean version of the Parent Questionnaire for Children developed by Thomas, Chess and Korn was applied to 395 Korean children whose ages ranged from 3 years to 7 years. Simultaneously the height and the weight were measured for each child and converted into percentile scale according to the Growth Curve and the Weight Percentile Table for the Height of Korean children. Statistical analysis was performed among 9 temperamental categories, height and weight percentiles for the age and weight percentiles for the height using the first-order partial correlation analysis, controlling for the familial mean income per month. Results showed that the more temperamentally difficult a child is, the lower weight he has when compared with the children of the same age or the same height. Although there were some differences, the tendency of the above findings was maintained both in male and female children. These results show that the temperament may influence the physical growth as well as the psychological development.

The purpose of this study was to examine the relationship between children's Temperamental Effortful Control and adolescents' Academic failure tolerance(AFT). Specifically, Grit effect as a mediator between Effortful Control and AFT was also determined. A total of 108 children participated as they were at age 8, and as they turned 14 years old. Children Behavior Questionnaire (CBQ) was measured to investigate children's Effortful Control, and Grit scale and AFT scale were measured to investigate adolescents' Grit and their response to failure. The results of this study showed that children's Effortful Control was significantly related to AFT. And adolescents' Grit was also positively related to adolescents' AFT. In addition, Effortful Control was related to Grit. Finally, Grit partly mediated the relationship between Effortful Control and AFT.

This study examined the relationship among temperament, social support and hope of institutionalized children. A total of 198 children, aged 10 to 13, recruited from 20 institutions in Seoul participated. Demographics, temperament, social support from friends, institution-family and school teacher, and hope were assessed by self-report. Results showed that in bivariate level, temperament and social support were significantly associated with level of hope. However, hierarchical multiple regressions indicated that children's hope was predicted only by age and social support from friends, institution-family and school teacher. That is, temperament was not contributed to predict hope, whilst social support contributed unique variance to the prediction of hope, controlling for age. The more social support the children felt they had, the higher levels of hope they reported. Further analyses revealed that support from friends, institution-family and school teacher were influential factors in explaining hope agency, while support from institution-family and school teacher were influential factors in explaining hope pathway of institutionalized children, controlling for age.

Replication of the factor structure of the TBAQ(Toddler Behavior Assessment Questionnaire Goldsmith, 1988) in Korean 2-year-old children was examined by Multitrait Multimethod matrix of observed and reported child behavior. Participants included 113 toddlers and their mothers. Three factors comprising 63 items were identified and labeled as easy, difficult and fearful. On the Child Behavior Checklist(Achenbach & Edelbrock, 1983) difficult temperament was positively related to externalizing while fearful temperament was positively related to internalizing problems. Observation of inhibited child behavior in both unfamiliar social and nonsocial situations demonstrated a positive relationship to observed inhibition of fearful temperament. Easy temperament correlated negatively with both social inhibition and internal behavior problems. Results supported construct validity of TBAQ factors for Korean 2-year-old children.

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.

Objectives : The purpose of this study was to investigate how the play habits, temperament, and environmental factors might affect childhood obesity. Methods : Two hundred sixty children, aged 4 through 6 years living in Seoul & Cheonan were surveyed by a questionnaire about the children's play habit and the parent's related factors such as weight, height, education, income. In addition the Korean version of the Parent Temperament Questionnaire for Children and the Korean version of the Family Environment Scale were also administered to parents of those children. The height and weight of those children were measured and the percentage of body fat was measured by Bioelectrical Impedance Fatness Analyzer. Result : 1) Among 260 children, 25 children were considered to be obese on the basis of both obesity index and percentage of body fat. 2) Parents of obese children showed a significantly higher educational level(p<0.05) and mothers of obese children had significantly more jobs(p<0.05) and showed higher body mass index(p<0.05) than those of nonobese children. 3) By observing play habits of children, obese children spent significantly longer time in watching TV and video(p<0.05), while nonobese children showed a trend to play outside(p<0.1). 4) On the Korean version of the Parent Temperament Questionnaire for Children, obese children showed significantly less activity than nonobese ones(p <0.05). 5) Family of obese children had significantly higher point on subscale of Achievement orientation, Intellectual-cultural orientation and Moral-religious emphasis of the Korean version of the Family Environment Scale(p<0.05). 6) Percentage of body fat of obese children was correlated with children's watching TV time, activity level, scores of Achievement orientation, Intellectual-cultural orientation of the Korean version of the Family Environment Scale and the both parent's education levels(p<0.05). Conclusion : Obese children showed hypoactivity and more watching TV time. And obese children's both parent had higher educational level and their mother had higher Body Mass Index and more jobs. Family of obese children had higher point on items of Achievement orientation, Intellectual-cultural orientation and Moral-religious emphasis. Family environmental factors influence on children's obesity through interaction of genetic and behavioral-psychological factors concomittently.
