Objectives: The purpose of this study is to identify the problems of verbal violence that adolescents face in the post-human age, when the non-face-to-face media is increasing. Methods: A survey was conducted on 305 adolescents, aged 14 to 16 years of middle school and high school students. The data were analyzed with the SPSS 25.0. Results: As a result of conducting multiple regression analysis to identify the type of conversation that affects verbal abuse of adolescents, a model with a conversation with family, conversation with other people, messenger conversation such as KakaoTalk, and video chat conversation was selected. The amount of explanation was 11.4%. (R2 = .114) Of these, non-face-to-face conversations have been shown to increase verbal violence, and face-to-face conversations with family have, in turn, lowered the risk. As a result of t-testing to examine the effect of verbal abuse experience on the verbal violence index, the damage experience was significant in depression (p = .042) and impulsive aggression (p = .021). (P = .000). Conclusion: This study reiterates the importance of family dialogue along with the fact that the development of various non-face-to-face media in the Fourth Industrial Revolution can have a negative impact on adolescent mental health.

Internet addiction in adolescents is an important social issue. In this study, sparse partial least-squares regression (SPLS) was applied to internet addiction data in Korean adolescent samples. The internet addiction score and various clinical and psychopathological features were collected and analyzed from self-reported questionnaires. We considered three PLS methods and compared the performance in terms of prediction and sparsity. We found that the SPLS method with the hierarchical likelihood penalty was the best; in addition, two aggression features, AQ and BSAS, are important to discriminate and explain latent features of the SPLS model.

This study analyzed the correlation between sensory processing types and stress responses in university students. A survey was conducted on 99 university students in Gyeonggi-do and Chungcheong-do. The survey contents consisted of Adolescent/Adult Sensory Profile and Stress Response Inventory. Data were analyzed using SPSS version 21.0 for descriptive statistics and Pearson correlation. As a result of the study, low-registration and sensory sensitivity were all correlated except for aggression of stress response, and sensory avoiding was all correlated of stress response. Sensory seeking was net related to any domain of stress response. Based on the results of this study, taking into account the correlation between sensory processing types and stress responses, it is recommended for convergence with other treatments to develop self-regulation strategies for coping with stress in university students.

The purpose of this study was empirical verification of the effect of adolescents' truancy experience on the self-awareness and emotional problems. For this, using the data of 2016 in the Korean Children and Youth Panel Survey(KCYPS), we compared and analyzed using t-test and multiple regression analysis the self-awareness and emotional problems of adolescents who experienced truancy and adolescents who did not. As a result of the analysis, adolescents with truancy experience had relatively low self-awareness, and statistically significant but low scores in self-identity and career identity. However, there was a clear difference in emotional problems, and truancy adolescents scored high in attention, aggression, physical symptoms, and depression. This proved that adolescents with experience of truancy were more exposed to emotional problems, and it was necessary to develop a support system and program for this.

Introduction：Research on attachment in view point of the developmental perspective which began in the 1940s progressed during several decades. Many investigators focused mother-child separation in early attachment studies, and moved to the relationship with childhood psychopathology. Recently attachment theory and research are moving forward along the intergenerational transmission of attachment patterns, and adolescents and adult mental disorders in the developmental perspectives. Methods：We surveyed the research papers through Medline search, attachment-related monographs, and review or original papers published in Korean journal. Results：Developmental attachment researches have demonstrated convincingly that insecure attachment in infancy is associated with attachment disorder; several childhood psychopatholgy, such as institutional care and adoption, aggression and behavioral problems, childhood anxiety disorders and depressive disorders, gender identity disorder and feeding disorder, and child abuse and maltreatment; peer relationship and social competency, and parental behaviors. Recently the methodological advances including the Adult Attachment Interview that systematically assesses the adults' recollections of the earlier parent-child relationship they experienced could move beyond attachment researcher's initial concern with infancy to consider attachment processes throughout the life span. We could find that the quality of attachment was associated with several mental disorders in adolescents and adults significantly. Conclusion：Attachment theory would have focused on more specific parent-child relationship than general parental behavior. Recent attachment theory underscores its evolutionary origins to promote development of infant and contribute to human survival in psychobiological bases. Advances in attachment research could unite interests in evolutional biology and developmental psychology in understanding early parent-child relationship, and apply to clinical issues concerning mental health throughout the life span.

Objectives: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. Methods: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. Results: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. Conclusions: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

This study examined how much Korean male middle school students used YouTube to determine if the social support from parents, teachers, and friends might moderate the relationships between YouTube overuse and internalizing and externalizing problems. Three hundred and twenty male middle school students completed questionnaires asking about their YouTube use, levels of YouTube addiction, internalizing and externalizing behaviors, and the degree of social support from parents, teachers, and friends. The results indicated that the YouTube addiction was positively related to the levels of internalizing and externalizing problems. Parental support moderated the relationships between YouTube addiction and internalizing problems. On the other hand, the moderating effects of teachers' or friends' supports were not significant. In contrast, teachers' support was the most crucial moderating factor regarding externalizing problems, while parental and friends' supports were only related to delinquency but not to aggression. These results suggest that the role of parental or teacher supports should be unique depending on the types of problem behaviors. Furthermore, the 'protective effects' of social support were not found in the highly addicted group, suggesting that the early prevention of YouTube overuse is a crucial intervention.

Objectives：This study was performed to introduce a psychoeducational family therapy model for the families of schizophrenic patient and to investigate the effect of this model on the changes in coping style and depressive symptoms of the family members, and in perception of emotional support by families and depressive symptoms of patients. Methods：Nine preschool children, 3-5 years old, experiencing physical injuries caused by attack from a psychotic patient at kindergarten, were evaluated for psychological assessments；Intelligence test, MSSB(MacArthur Story-Stem Battery), H-T-P test(House-Tree-Person test). And their parents completed rating scale, KPI-C(Korean Personality Inventory for Children about children’s psychological conditions). Results：With respects to the contents and emotional reactions of MSSB, 9 preschool children showed generally high levels of anxiety, depression, avoidance, aggression, probably related to the traumatic experiences. Even though children couldn't verbally report directly about their traumatic experiences, in both MSSB, structured play narrative assessment tool, and HPT, free drawing and association test, they demonstrated psychiatric problems through reenactment plays, regardless of clinical diagnoses. Conclusion：Present study allowed us the chance to see beyond the outer pathological behaviors of PTSD in preschool children, through deeper evaluations of their mental representation. These preliminary data suggest deep understanding of internal representation would be of help for thorough evaluations and treatment plan for preschool children, experiencing severe trauma.

The clinical assessment for preschool children who are known to have problems in selfreporting tends to be dependent on outsiders' reporting. Thus, the direct assessment of children's inner experience, thoughts and feelings is difficult. MacArthur Story-Stem Battery(MSSB) developed to learn more about preschool children's mental representation in play is used in this study to help assess clinical preschool children through developmental study of normal children's mental representation. Fifty five children(32boys and 23girls) who performed MSSB, IQ Test, Peabody Picture Vocabulary Test-Revised(PPVT) were videotaped and were analyzed. The results of this study were as follows：1) Children frequently displayed negative mental representation such as atypical negative response, reparation/guilt, punishment, personal injury and so on during emotionally laden play situation. 2) Mental representation of parent appeared positive, disciplinary, and negative in respective. 3) As a result of factor analysis of MSSB content themes, aggressive, prosocial, and oppositional content theme composites were generated. Aggressive content included atypical negative response, aggression, personal injury, and exclusion. Prosocial content included affection, affiliation, and reparation/guilt. Oppositional content included punishment and non-compliance. 4) Mental representation of parent and content themes showed significant correlation. Positive, negative, and disciplinary representation were significantly correlated for prosocial(r=0.40), aggressive (r=0.52), and oppositional(r=0.75) content theme respectively. 5) Among the correlations between parental mental representations and emotional responses, positive parental representation and anxiety showed significant negative correlation(r=-0.43). 6) Among the correlations between content themes and emotional responses, there were significant positive correlations between aggressive(r=0.28) and oppositional content themes(r=0.29) and distress, and were significant negative correlations between prosocial content theme and concern(r=-0.29) and anxiety(r=-0.43). According to the above results, preschool children frequently displayed negative mental representation in emotionally conflictual play situation. Children with more prosocial themes in their stories exhibit more positive parental mental representation. Also, children with more aggressive themes tend to display more negative parental representation and negative emotional responses.
