The purpose of the current study was to examine the risk factors of young children’s smartphone addiction in a longitudinal study design. Data collected from 313 participants (mean age, 4.5 ± 0.82 years; male, 49.8%) over 4 years for Kids Cohort for Understanding of Internet Addiction Risk Factors in Early Childhood were analyzed in this study. Mixed effect models were used to evaluate the influence of various variables on the repeated measures of smartphone addiction tendency in young children over time. The multi-level analysis showed that parents’ lack of control over children’s smartphone use (t = −4.523; 95% confidence interval [CI], −7.32, −1.72), and parents’ higher smartphone addiction proneness (t = 6.340;95% CI, 0.23, 0.440) predicted higher smartphone addiction tendency in young children.The responsibility of the parents to prevent their children from becoming addicted to smartphones should start in a very early age when they start using the smartphones.

There have been a few case reports that clozapine, an atypical antipsychotic, caused acute renal failure of interstitial type. Here we report a case of a 38-year-old Korean male patient with treatment-resistant bipolar I disorder who developed acute renal failure after the initiation of treatment with clozapine. We describe the clinical and laboratory findings of the case and discuss the measures for early detection of this life threating condition. Within our knowledge, this is the first report of clozapine-induced acute renal failure in South Korea.

The purpose of the present study was to examine the severity of suicidal ideation of the older adults according to the amount of involvement in grandchild care. Data for this research were drawn from a cross-sectional study conducted on community-dwelling adults aged 65 years or older. The 922 participants were divided into three groups according to their involvement in grandchild care: 18.5% had provided daily care, 12.4% had provided occasional care, and 69.1% had never cared for their grandchildren. ANCOVA analysis showed that the scores for depression was significantly lower in the group which took care of their grandchildren occasionally compared to the other two groups. The scores for suicidal ideation was significantly higher in the group which had never taken care of their grandchildren compared to the other two groups. Current study suggests that grandparenting may have a positive effect on suicidal ideation of the older adults.

Objective: This study investigated the effect of suicide prevention education on attitudes toward suicide among police officers. Methods: We used an anonymous questionnaire for 518 officers and surveyed the demographic profiles and examined attitudes toward suicide utilizing the Attitudes Towards Suicide Scale (ATTS) (1=totally agree, 5=totally disagree). Our study divided participants into two groups, based on whether or not they had received suicide prevention education, and examined the differences in attitudes toward suicide between the groups. Results: Of the total population, 247 (47.7%) officers had received suicide prevention education. The education group thought suicide as a predictable matter, disagreeing significantly more with the ATTS factor ‘suicide is unpredictable’ (3.36 vs. 3.35; p=0.001) compared with the no education group. Also, the education group more perceived suicide as a cry for help and at the same time disagreed more with the notion ‘suicidal thoughts will never disappear’ (2.08 vs. 2.26; p=0.025, 3.2 vs. 3.05; p=0.035, respectively). Conclusion Officers with experience in suicide prevention education showed more positive attitude toward suicide and suicide prevention. These findings suggest a need to organize more opportunities of suicide prevention educations, such as making the training mandatory for police officers.

OBJECTIVES: Many studies have demonstrated comorbidities and overlapping symptoms in attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD). The purpose of this study was to examine the functional impairment in subjects with ADHD, ODD, and in those with both ADHD and ODD. METHODS: 172 male subjects, aged 6 to 15 years old, were enrolled in this study. Based on diagnoses made by applying the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime (K-SADS-PL), the subjects were categorized into four groups: ADHD group (n=64), ODD group (n=17), ADHD+ODD group (n=28), and control group (n=63). The Child and Adolescent Functioning Impairment Scale (CAFIS) was used to measure the functional impairment of the subjects. CAFIS consists of four subscales : Family relationship, Teacher relationship, Peer relationship, and Academic achievement scales. A high CAFIS score implies high functional impairment. Analysis of covariance was conducted to compare the scores between the four groups. RESULTS: Both the ODD and the ADHD+ODD groups had significantly high scores for Parent relationship compared to that of the ADHD group. Compared to the control group, both the ADHD and the ADHD+ODD group had significantly higher scores for Peer relationship and Academic achievement, whereas, the ODD group showed no significant difference from the control group on those two subscales. CONCLUSION The present study showed that subjects with ADHD and ODD have different functional impairment characteristics. The subjects' relationships with their parents were worsened by the presence of ODD. Peer relationships and Academic achievements were significantly affected by the presence of ADHD.

Objective: The purpose of the present study was to develop and validate the Korean version of the clinician-administered KSADSCOMP, which is the recently updated, web-based computerized version of the Kiddie Schedule for Affective Disorders and Schizophrenia for school-age children (KSADS). Methods: A total of 71 participants (mean age=12.04±3.86 years, female=29.57%) participated in the study. A child-adolescent psychiatrist established a diagnosis for the participant after a thorough psychiatric interview with the participant and the parent. Researchers who were blind to the diagnoses administered the clinician-administered KSADS-COMP to the parents and participants. The gold-standard diagnoses made by child-adolescent psychiatrists were compared to the current diagnoses generated by the clinician-administered KSADS-COMP. Percent agreement, Cohen’s Kappa, Gwet’s first-order agreement coefficient (AC1), sensitivity, specificity, positive predictive value, and negative predictive value were calculated. Results: Gwet’s AC1, our preferred measure of agreement, showed excellent range between 0.78 and 1. Sensitivity, specificity, positive predicted value and negative predictive value also showed high scores. Conclusion The current study demonstrated excellent criterion validity of the Korean version of the clinician-administered KSADSCOMP, though the small sample size could be a limitation. The current study was the first study to examine the criterion validity of the KSADS-COMP. Due to its readily usable format and efficient and accurate diagnostic process, widely-use of KSADS-COMP is expected.

OBJECTIVES: The aim of this study was to investigate the variables influencing acceptability and perception towards suicide among the elderly in Bucheon city, South Korea. METHODS: A total of 1099 elderly over 65 years old participated in this study. The subjects completed a self-questionnaire including their demographic characteristics, psychiatric characteristics, factor 1 and 4 of the Attitudes Towards Suicide-20, and Geriatric Depression Scale Short Form Korea Version. One-way analysis of variance was performed to identify the variables associated with the acceptability and perception towards suicide. RESULTS: As result of this study, the demographic characteristics (older age, lower education level, lower economic state, bereavement, divorce or separated marital status, and life without spouse) and psychiatric characteristics (psychiatric past history, treatment history, and suicidal attempt history) were found to be associated with a more acceptable attitude toward suicide. In addition, a lower education level, no psychiatric history, and no psychiatric treatment history influenced the lack of perception to suicide. CONCLUSION: For public services to prevent suicide of the elderly population who lack spontaneity and accessibility to suicidal evaluations, it would be important to focus on the variables identified in this study for enhancing the effectiveness of the services.

Objectives: The aim of this study was to investigate elementary school teachers' knowledge and perception of attention-deficit/hyperactivity disorder (ADHD). Variables associated with the teacher's tendency to recommend treatment to parents of the ADHD children were also evaluated. Methods: A total of 73 elementary-school teachers completed a self-questionnaire regarding their demographic characteristics, previous experience, and perception of ADHD children. Knowledge of the Attention Deficit Disorders Scale (KADDS) was used to examine the participants' level of knowledge of ADHD. Multivariable logistic regression analysis was performed to identify the variables associated with the participants' tendency to recommend treatment to parents of ADHD students. Results: The average correct rate was 64.4% on the KADDS. 64 (87.7%) participants had a positive perception of medical treatments of ADHD, but only 41 (56.2%) participants reported that they would recommend treatment to parents of ADHD children. Teachers that were older and married were more likely to recommend treatment. The teacher's sense of efficacy was found to have a positive association with the tendency to recommend treatment to parents. Conclusion Educational programs and specific guidelines that can improve the knowledge of ADHD and self-efficacy as a teacher are needed for elementary school teachers. Teachers should understand that they have significant roles in the management of ADHD children.
