PURPOSE: This study was intended to integrate the evidence of intervention for child and adolescent perpetrators of school violence through an integrative literature review. METHODS: Using combinations of the terms ‘bullying’, ‘school violence’, and ‘intervention’ as key words, the researchers searched eight electronic databases for relevant studies. Fifteen studies were selected through full-text screening of related research published in academic journals before June 2018. The framework was used to identify the selected studies' intervention patterns and classify the various intervention components. The extracted intervention components were grouped into potential themes to determine whether the researchers clearly showed the interventions in the studies. RESULTS: The intervention components of 15 selected studies were categorized into five themes: 1) Utilizing intervention techniques for voluntary participation, 2) Enhancing self-awareness, 3) Strategies to improve emotional intelligence, 4) Promoting interpersonal skills, and 5) Emphasis on responsibility through future vision experience. CONCLUSION: As a result of analyzing interventions for children and adolescent perpetrators of school violence, five components were derived. It is suggested that these components should be considered in the field, and intervention programs development and research using them are needed.

OBJECTIVES: The purpose of this study was to examine the differences according to depressive symptom-related difficulty status. METHODS: 2828 participants were a divided into depressive symptom-related difficulty group (difficult group, n = 774), and a non-depressive symptom-related difficulty group (not difficult group, n = 2054). The psychological character of the participants were assessed using the Korean version of the Patient Health Questionnaire-9 (PHQ-9), Satisfaction with Life Scale (SWLS), the 12-item General Health Questionnaire (GHQ-12), and Conner-Davidson Resilience Scale (CD-RISC). Statistical analyses were done using t-test, chi-square, and analysis of covariance (ANCOVA). RESULTS: Compared with the no difficulty group, the difficulty group reported significantly higher score in all items of PHQ-9. The score of "feeling tired" was the highest and the score of "suicidal ideation" is the lowest in both groups. ANCOVA analysis that is adjusted with the total score of PHQ-9 showed the differences in SWLS, GHQ-12, and CD-RISC scores between the difficulty group and the no difficulty group. CONCLUSIONS: The findings suggest that there are different characters on PHQ-9, SWLS, GHQ-12, and CD-RISC according to depressive symptom-related difficulty. Therefore, it is required not only to evaluate depressive symptoms in patients with depression, but also the depressive symptom-related difficulty to understand these differences.

OBJECTIVES: The purpose of this study was to evaluate the properties of the Beck Depression Inventory-II (BDI-2) via the internet. METHODS: Participants included 1967 students of a university. A confirmatory factor analysis was performed to test whether the factor structure of the BDI-2. Convergent validity was assessed by correlating the scores on the BDI-2 with those on other scales. RESULTS: Two-week test-retest reliability was high (r=0.84) and internal consistency was good (Cronbach's alpha=0.882). The BDI-2 showed a good criterion validity with strong correlation with Patient health questionnaire 9 (PHQ-9). Factor structure of the BDI-2 was established using the three-factor structure, which explained 43% of the total variance. CONCLUSION: The results of the current study indicate that the BDI-2 is an effective and valid scale for evaluation of depression among Korean university students. The findings suggest that the BDI-2 is a promising assessment tool for use in depression and study of depression via the internet.

We developed a Korean translation of the Internet Addiction Test (KIAT), widely used self-report for internet addiction and tested its reliability and validity in a sample of college students. Two hundred seventy-nine college students at a national university completed the KIAT. Internal consistency and two week test-retest reliability were calculated from the data, and principal component factor analysis was conducted. Participants also completed the Internet Addiction Diagnostic Questionnaire (IADQ), the Korea Internet addiction scale (K-scale), and the Patient Health Questionnaire-9 for the criterion validity. Cronbach's alpha of the whole scale was 0.91, and test-retest reliability was also good (r = 0.73). The IADQ, the K-scale, and depressive symptoms were significantly correlated with the KIAT scores, demonstrating concurrent and convergent validity. The factor analysis extracted four factors (Excessive use, Dependence, Withdrawal, and Avoidance of reality) that accounted for 59% of total variance. The KIAT has outstanding internal consistency and high test-retest reliability. Also, the factor structure and validity data show that the KIAT is comparable to the original version. Thus, the KIAT is a psychometrically sound tool for assessing internet addiction in the Korean-speaking population.

OBJECTIVES: Despite the growing research interest in the role of immunological markers in schizophrenia, a few studies, with conflicting results, have focused on the association between high sensitivity C-reactive protein (hs-CRP) levels and clinical characteristics in schizophrenia. The aim of the present study was to examine the association of serum hs-CRP with psychopathology in schizophrenia. METHODS: Fifty-five inpatients with schizophrenia or schizoaffective disorder were enrolled. Serum levels of hs-CRP were measured, and each patient was assessed with the Korean version of the Positive and Negative Syndrome Scale (PANSS). RESULTS: In correlation analysis of hs-CRP with PANSS subscales, positive subscale score has significant positive correlation (r = 0.271, p = 0.046). In independent t-test analysis, subjects with hs-CRP > 0.3 mg/dL (elevated CRP group, n = 43) had significantly higher PANSS positive subscale score (t = -3.273, df = 24.107, p = 0.003) than those with hs-CRP < or = 0.3 mg/dL (normal CRP group, n = 12). CONCLUSIONS: Elevated serum levels of high sensitivity C-reactive protein in schizophrenia are associated with the severity of psychotic symptoms.

Objective: This study aimed to examine personality profiles and behavioral problems of children with nail biting (NB) to gain insight into the developmental trajectory of pathological NB. Methods: 681 elementary school students were divided into non NB (n=436), occasional NB (n=173) and frequent NB group (n=72) depending on the frequency of NB reported in Child Behavioral Checklist (CBCL). Children’s personality was assessed using the Junior Temperament and Character Inventory (JTCI), and behavioral problems were assessed using the CBCL. Latent Profile Analysis (LPA) was performed using JTCI profiles to classify personalities of the children with NB (belonging to frequent and occasional NB group, n=245). Results: For subscale scores of CBCL, the total, internalizing, externalizing, anxious/depressed withdrawn/depressed, depression, thought, rule-breaking, and aggressive behavior problems, were most severe in the frequent NB group followed by occasional NB and non NB group. LPA of personality profile in children with NB revealed four classes (‘adaptiveness,’ ‘high reward dependence,’ ‘low self-directedness,’ and ‘maldaptiveness’). The four personality classes demonstrated significant group differences in all of the CBCL subscales. Children who showed low self-directedness and cooperativeness and high novelty seeking and harm avoidance personality profiles demonstrated highest tendency for problematic behavior irrespective of the frequency of NB. Conclusion Children with NB reported significantly more problematic behaviors compared to children without NB. Children with specific personality profile demonstrated higher tendency for problematic behavior irrespective of the frequency of NB. Therefore, accompanying personality profiles should be considered when assessing behavioral problems in children with NB.

Several studies have linked teachers' personality characteristics and sense of efficacy to stress. However, investigating the relationship between these three constructs in this context was limited. This study aims to investigate the relationship between personality, sense of efficacy and perceived stress among Korean teachers. A total of 137 teachers working in elementary, middle, and high schools located in Seoul, South Korea were recruited for the study. The participants were administered Temperament and Character Inventory, Teacher's Sense of Efficacy Scale (TSES), and Perceived Stress Scale. The TSES was negatively correlated with harm avoidance and positively correlated with persistence, self-directedness, cooperativeness, and self-transcendence. Perceived stress was positively correlated with harm avoidance and negatively correlated with persistence and self-directedness. The path analysis showed that harm avoidance directly predicted perceived stress (β=0.37, 95% CI=0.21–0.53, p=0.002), and self-directedness and persistence predicted one's sense of efficacy (β=0.18, 95% CI=0.01–0.39 and β=0.31, 95% CI=0.10–0.47), which predicted perceived stress (β=-0.21, 95% CI=-0.39 to -0.02). The results of the present study indicate that harm avoidance might be associated with stress-proneness, while persistence, self-directedness, and sense of efficacy might act as protective resources against stress in Korean teachers.

OBJECTIVES: The objective of this study is to find out the differences in psychopathology, temperament, and character factors between young adults with and without childhood attention-deficit hyperactivity disorder (ADHD) symptoms. METHODS: The subjects consisted of 314 university students (male=72, female=242) in Gongju. They were divided into childhood ADHD group (N=54) and normal group (N=260) to the Wender-Utah Rating Scale. Participants were assessed using Korean Adult ADHD Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, Kimberly Young's Internet Addiction Test, Barratt Impulsiveness Scale, Paranoia Scale, Korean-Schizotypal Ambivalence Scale, Lubben Social Network Scale, and Temperament and Character Inventory-Revised. Descriptive statistics, t-test, chi-square, spearman correlation, and stepwise multiple regression were applied to analyze the data. RESULTS: Participants with childhood ADHD symptoms had high level of adult ADHD symptoms (p<.001), impulsiveness (p=.001), depression (p<.001), anxiety (p<.001), internet addiction (p<.001), paranoia tendency (p<.001) and low level of self-esteem (p<.001) compared to normal group. Self-directedness (p<.001) was lower, Harm avoidance (p=.001) and Self-transcendence (p=.029) were higher in the childhood ADHD group. In correlation and stepwise multiple regression, childhood ADHD symptoms were significantly associated with cooperativeness (r=-0.515 and beta=-0.547, p<.001 respectively). CONCLUSION: This result showed that young adults with childhood ADHD symptoms had various forms of psychopathology and childhood ADHD symptoms were influenced by character such as cooperativeness. Therefore, more thorough evaluation regarding childhood ADHD symptoms is needed.

OBJECTIVE: The current study aimed to examine the association of implicit self-esteem, explicit self-esteem and their interaction with paranoia and attributional bias. The relationship of the size and the direction of the discrepancy between implicit and explicit self-esteem with paranoia and attributional bias was examined. METHODS: A total of 128 female college students participated. We administered the Implicit Association Test to assess implicit self-esteem, and the Rosenberg Self-Esteem Scale to measure explicit self-esteem. Paranoia Scale was used, and the attributional bias was assessed using the Ambiguous Intentions Hostility Questionnaire. RESULTS: Results showed that explicit but not implicit self-esteem was negatively associated with paranoia, blame bias and hostility perception bias in ambiguous situations. The interaction of implicit and explicit self-esteem was associated with hostility perception in ambiguous situations. As for the discrepancy, the size of the discrepancy between implicit and explicit self-esteem was positively associated with hostility perception in ambiguous situations. Moreover, the direction of the discrepancy was specifically relevant: damaged self-esteem (high implicit and low explicit self-esteem) was associated with increased levels of paranoia, blame bias and hostility perception in ambiguous situations. CONCLUSION: These findings provide new insights into the role of the implicit and explicit self-esteem in attributional bias and paranoia and point to damaged self-esteem as a possible vulnerability marker for illogical attribution of blaming others and perceiving hostility in social situations.
