The purpose of this study was to investigate the gender differences of peer relationship and to analyze the effects of the individual psychology and family variables on adolescents' peer relationships. The subject of this study were 1,444 students of second and third grade of middle school who reside in Seoul and 1,397 self reported questionnaires were used for final analysis. The major results of this study were as follows. First, the findings suggested that there were significant differences between female and male adolescents in peer relationships. Female adolescents' friendship quality was higher than male adolescents', and male adolescents' peer victimization was higher than female adolescents'. Second, higher self-esteem, positive parenting behavior, higher level of parental supervision and lower level of interparental conflict predicted higher level of friendship quality among male and female adolescents. Higher depression, lower self-esteem, positive parenting behavior, lower level of parental supervision and higher level of interparental conflict predicted higher peer victimization among male and female adolescents.

We spend about one-third of our life sleeping. Although the influence of sleep on various cognitive and affective functioning is recognized, relatively less is known about its consequences on interpersonal relationships. The present study examines whether sleep contributes to adolescent's peer intimacy; specifically, given the role of sleep in memory consolidation, it was assumed that a good sleep will enhance social relationships by positively refurbishing memories of social episodes. As predicted, young teenagers' sleep quality predicted increased peer intimacy, partly through the positive memory of social events, in a sample of middle school (Study 1) as well as high school participants (Study 2). To investigate the causal link, in Study 2, memory recollections were repeatedly measured for a week. Sleep quality during the week predicted how social, but not non-social episodes were positively remembered. The function and importance of sleep quality are discussed in the context of interpersonal relationships.

The purpose of this study was to investigate how children's temperament and relationships with teachers affect their peer interaction. For this purpose, two surveys were conducted on mothers and teachers of 326 four- and five-year-old children attending four kindergartens in Gyeonggi Province. The data were analyzed by using PASW 18.0 to carry out hierarchical regression and post hocanalyses. The results showed that closeness to teachers moderated the effects of children's emotionality on their positive peer interaction. On the other hand, children's temperaments including emotionality and activity, and their relationship with teachers were directly influential on their negative peer interaction; no interaction effect was found between their temperament and relationships with teachers. It was concluded that the quality of teacher-child relationships could promote children's positive peer interaction while it could also reduce their negative interaction with peers. However, the temperament of children played limited roles in their negative peer interaction.

The present study was to investigate the mediating and moderating effects of self-acceptance on the relationship between perfectionistic self-presentation and peer relationship quality in adolescents. Two hundred and sixty-one middle school students were surveyed. The results were as follows. First, self-acceptance had a full mediation effect on the relationship between perfectionistic self-presentation and peer relationship quality. That is, peer relationship quality was only indirectly affected by perfectionistic self-presentation through self-acceptance. Second, self-acceptance had a significant moderating effect in the relationship between perfectionistic self-presentation and peer relationship quality. Perfectionistic self-presentation did not have a statistically significant impact on peer relationship quality in the group with low self-acceptance, but it did in the group with high self-acceptance. Therefore, this study suggests the need for counseling and educational approaches to improve adolescents self-acceptance by verifying the effect of self-acceptance in perfectionistic self-presentation and peer relationships.

Purpose: This study aimed to determine the level of health-related quality of life (HRQoL) of children and adolescents who received hematopoietic stem cell transplantation (HSCT) and to examine factors influencing HRQoL. Methods: This cross-sectional descriptive study involved 85 participants aged 10 to 19 years who received treatment from 3 months to 5 years after HSCT. Symptom experiences, stress and coping, self-esteem, social support, and HRQoL were measured. Descriptive analysis, the independent t-test, one-way analysis of variance, Pearson correlation analysis, and stepwise multiple regression were used for data analysis. Results: The mean HRQoL score was 72.26 points out of 100. HRQoL showed statistically significant correlations with symptom experiences, stress, self-esteem, social support, satisfaction with peer relationships, and perceived attentiveness of the medical team. The most influential predictors of HRQoL were symptom experiences (β=-.51, p<.001) and satisfaction with peer relationships (β=.32, p<.001). Conclusion: The experiences of different symptoms by children and adolescents who receive HSCT must be considered. In addition, nursing interventions, such as self-help meetings with peer groups, should be provided to improve their HRQoL.

The purpose of this study was to explore how overly positive self-estimations in peer relationships relate to subjective well-being and to the occurrence of interpersonal behaviors supporting basic psychological needs among elementary school students. This study tested the optimal margin hypothesis of positive illusion by examining the curvilinear relationship between these variables. The sample consisted of 346 fifth and sixth grade students. The self-criterion residual method was used to derive self-estimation bias scores by regressing the real peer relations index (i.e., In-degree) on their perceived peer relationship qualities. The results showed that girls more strongly overestimated the quality of their peer relationships than boys. Self-estimation biases had a positive curvilinear relationship with negative affects and a negative curvilinear relationship with relatedness needs supporting interpersonal behaviors. These results supported the existence of the optimal margin of positive illusion because overestimations of the quality of peer relationships were associated with lower levels of negative affects and relatedness needs-supporting interpersonal behaviors, though these benefits flattened out and no further benefit was observed after an optimal level of overestimation. However, self-estimation bias was linearly associated with positive affect, autonomy needs-supporting interpersonal behaviors, and competence needs-supporting interpersonal behaviors. These results indicated that optimal margin hypothesis was not supported for all outcome variables.

The purpose of this study is to examine the mediation effects of relationships of parent-child and between-peers based on the effects of economic difficulty on quality of life of elementary school students. Data was obtained from students (N= 493) at seven elementary schools in Choongbuk Province and analyzed with SPSS 12.0 and Structural Equation Modeling with AMOS 5.0. The major findings are as follows: economic difficulty gives a direct effect on elementary students' quality of life and is mediated with parent-child and between-peers relationships. Also, economic difficulty influences children's quality of life when a parent-child relationship is combined with a between-peers relationship. On the basis of these results, this study suggests that welfare centers and elementary schools have to teach students to have desirable sense of value. Also, schools need to provide education programs for parents to improve parent-child relationship and various activities for students to develop between-peers relationship.

This study was designed to examine the casual relationships among trust evaluation factors, trust, customer satisfaction, and re-use intention in the P2P file sharing service. We applied structural equation model to test the hypotheses and research model. As a result of this study, trust evaluation factors affect trust and customer satisfaction and both of trust and customer satisfaction affect re-use intention respectively and significantly. Also trust affects customer satisfaction significantly. Specifically, trust was empirically confirmed as one of the important factors preceding customer satisfaction and re-use intetion in the P2P file sharing service. Therefore, this study shows that trust is important factor that P2P companies have to emphasize to raise user satisfaction and performance.

The purpose of this study was to investigate institutionalized adolescents'perception of meaningful persons and to analyze the features of their interpersonal relationships. 9 middle school students of 3 child welfare facilities were observed and participated in depth-interviews. Results indicate that there is a difference in adolescents'family image according to their experience before institutionalization. They want care-givers of institution to offer more emotional support to them. And they perceive much social support from other adolescents who're living with them. But, the findings suggest that their peer relationships have some limitations because of institutionalization itself and various restriction on their behaviors. Lastly, they want more intimate relationship with supporters in addition to financial sponsorship. In conclusion, institutionalized adolescents'interpersonal relationships are related closely to the environmental properties. Therefore, concerns should be directed toward improving the quality of social and psychological environment of institutions. And various programs should be provided to support institutionalized adolescents'social development.

The purpose of this study was to examine the role of self-esteem (SE) and cooperation (CO) in the effect of parental attitudes (PA) as perceived by children on the quality of peer relationships (PR). To this end, the data of 1299 boys and 1278 girls in 4th grade were analyzed using the Korean Children and Youth Panel Survey data. The correlation analysis, confirmatory factor analysis, structural equation modeling using phantom variables and bootstrapping were performed by using SPSS and AMOS programs. The results of this study are as follows. First, perceived PA had a significant effect on SE, CO, and PR, SE had a significant effect on CO and PR, and CO had a significant effect on PR. Second, the serial multi-mediating model that assumed that SE and CO mediate the relationship between PA and PR was found to be appropriate. These results suggest that it is important to consider the child's self-esteem and cooperation with parenting attitudes to improve the child's peer relationship. Future research and clinical implications were discussed.
