The purpose of this study was to estimate the prevalence of ADHD based on estimation of ADHD rating scale between mother-teacher and teacher-teacher. In total, 491 mothers and 23 teachers rated 689 5-year-old children on the K-ADHDDS. Descriptive statistics, in addition to independent and paired samples t-test were performed. Overall, the percentages of children with ADHD on the rating scale were 3% in combined type, 7.1-8.6% in predominately hyperactive-impulsive type, and 4.2% in predominately inattentive type. Boys tended to show greater tendency of ADHD than girls’: Overall, ADHD tendency in boys was 1.3 times greater than girls. Specially, 2.3 times more for hyperactivity, 1.4 times more for impulsivity, and 3.4 more for inattention. The correlation between mothers’ and teachers’ ratings were .35 for total, .40 for hyperactivity, .24 for impulsivity, and .28 for inattention, and there were no significant differences. Alternatively teacher and teacher ratings were .71 for total, .70 for hyperactivity, .70 for impulsivity, and .67 for inattention, and there were significant differences in inattention subscale(p < .01).

Objectives Risk taking has been implicated in the development of various psychiatric disorders. Previous studies have indicated that risk taking behavior is associated with high levels of impulsiveness. Risk taking entail uncertain situation that outcome probability is unknown. This study tested impulsivity, intolerance of uncertainty and risk taking behavior. Methods A total of 73 participants completed a test battery comprised of the UPPS-P scale as a psychometric measurement of five dimensions of impulsivity, Intolerance of Uncertainty Scale, and Balloon Analog Risk Task (BART) as a behavioral measure of risk taking. The Pearson correlation analysis was used. Results The sensation seeking factor was positively correlated with BART measure (r = 0.27, p = 0.02). Specifically, the relationship between sensation seeking and BART was significant in females. Conclusions Among the five factors of UPPS-P, only the sensation seeking factor predicts risk taking propensity.

Objectives This study aims to investigate possible associations between proneness toward smartphone addiction and certain psychopathological variables to evaluate the psychopathological meaning of smartphone addiction. Methods Questionnaires were assigned to 755 adults between September and November 2012. We used the Korean Smartphone Addiction Proneness Scale (SAPS), the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), the Obsessive-Compulsive Inventory-Revised (OCI-R), and the Barratt Impulsivity Scale-11 (BIS-11). Subjects were classified into two groups according to the scores of the SAPS ; the addiction proneness group and the normal-user group. Results The addiction proneness group had significantly higher scores than the normal-user group in the BDI, BAI, OCI-R, and BIS-11. The scores of the SAPS were positively correlated with the scores of the BDI, BAI, OCI-R, and BIS-11. Using logistic regression analysis, smartphone addiction proneness showed a significant association with BIS-11. Conclusions The results of this study suggest that smartphone addiction proneness may be associated with depression, anxiety, obsessive-compulsive symptoms, and impulsivity. Furthermore, impulsivity could be a vulnerability marker for smartphone addiction proneness.

This study identified the severity of youth gambling behavior and analyzed the impact of stress, impulsivity, peer attachment and social interest on youth gambling behavior. Based on the results of the study, the government sought to help understand teenagers who are addicted to gambling and to help them maintain psychological and social stability and healthy living. A total of 237 high school students were surveyed. According to the analysis, the prevalence rate was found to be 3.4 percent of the problem gambling group and 9.3 percent of the medium-risk gambling group, and a total of 12.7 percent was addiction. Low-risk gambling groups accounted for 16.9 percent and non-problem gambling groups accounted for 70.5 percent. By gender, male students have more serious gambling problems than female students. As a result of dividing the group that experienced gambling more than once and the group that did not experience gambling into gambling group and non-gambling group, the two groups showed significant differences in impulsiveness, avoidant attachment, and interest in others. Furthermore, a correlation analysis was conducted to examine the relationship between these factors and the level of gambling behavior, showing that only impulsivity was significant.

Cognitive behavioral therapy (CBT) is effective for people with an addiction tendency. This study aims to implement a CBT program for college students at high risk of smartphone addiction and investigate the impact of the program on their desire to use a smartphone, depression, impulsivity, and anxiety. Baseline/post-intervention evaluation and the ABA' single-case experimental design were used. The study consisted of the baseline phase (A), pre-evaluation, intervention phase (B), post-evaluation, and baseline phase (A'). Six participants were enrolled, and the main outcome variables were daily changes in the desire to use a smartphone and changes in depression, impulsivity, and anxiety after the program. Prior to the intervention, all six participants had mild to moderate depression, but after the intervention, three were normal, two had mild depression, and only one had moderate depression. Impulsivity and anxiety scores decreased after the intervention, with anxiety scores showing the most dramatic change. The percentage of non-overlapping data for the baseline phase (A)-intervention phase (B) was more than 75% and that for baseline phase (A)-baseline phase (A') was 100% for all 6 participants. This study presented a good protocol for people with low access to psychological therapy. We expect the findings will be highly useful for people suffering from psychological difficulties due to smartphone addiction.

This study investigated the differences of internet addiction by gender and the psychological states(depression, anxiety, impulislvity and aggression) by internet addiction groups and the relationship of depression, anxiety, impulsivity and aggression with internet addiction by resilience as moderator. The 529 college students (male: 212, female: 317) of 5 universities of Jeonbuk Province participated in this study. Main results are as follows; First, the intenet addiction level of male college students was higher than female students, and the higher internet addiction was, the higher depression and impulsivity were. Second, depression. anxiety, impulsivity and resilience were correlated with internet addiction. But aggression was not correlated with it. Third, anxiety and implusivity(male college students), depression and impulsivity(female college students) were correlated with internet addiction or overuse. Fourth, resilience was proved to function as moderator in the prediction of depression on internet addiction of only female college students. The limitation and future tasks were discussed.

The purpose of this study is to investigate the lifestyle factors influencing behavioral problems such as Inattention, hyperactivity/impulsivity, and internet overuse in elementary and middle school students. Data from 889 elementary school students and 676 middle school students were used and teacher reporting on students' attention deficit and hyperactivity and impulsivity symptoms was also included in the analysis. Lifestyle included opportunities for family interaction, sleep, watching TV, playing Video games, eating breakfast, eating junk food, and private education. As a result of stepwise regression analysis, Video games, junk foods, and family interactions significantly predicted the inattention of elementary and middle school students. Video games, TV, junk foods, and family interactions significantly predicted elementary school students' hyperactivity and impulsivity, but the lifestyle variables hardly accounted for the hyperactivity/impulsivity of middle school students. Video game, and family interactions significantly predicted Internet overuse for both elementary and middle school students. Current study suggest that family interaction opportunities and the use of video games, TV and junk food should be considered to intervene in behavior problems.

The purpose of this study was to 1) explore the effectiveness of a college-level self-management (SM) course in improving a target behavior and reducing impulsivity, 2) investigate improvements in other non-target self-control behaviors(generalization of self-control), and 3) determine whether change in impulsivity could predict the generalization of self-control. A total of 128 College students who took the SM course were included. Participants completed the computerized delay-discounting task, self-report impulsiveness scale, and general self-control behavior questionnaire at the beginning and end of the course. After participants had defined their target behaviors, they self-monitored and recorded their behaviors everyday throughout the course. Results revealed that 63% of the participants successfully changed their target behaviors after the course. Although differing depending on the type of target behavior, thoes who successfully changed their target behaviors reported decreases in impulsivity and increases in other self-control behaviors such as physical exercise, healthy diet, study habits, and time management, after the course. Furthermore, the decrease of impulsivity significantly predicted the generalization of self-control in the exercise and diet groups. The results indicate that reduced impulsivity is related to improvements in a target behavior and general self-control behaviors in other spheres. Implications and limitations are also discussed.

Impulsiveness is an important component of many psychiatric disorders including Attention-deficit/hyperactivity disorder (ADHD). Although the neurobiological basis of ADHD is unresolved, behavioral tests in animal models have become indispensable tools for improving our understanding of this disorder. In the punishment/extinction paradigm, impulsivity is shown by subjects that persevere with responding despite punishment or unrewarded responses. Exploiting this principle, we developed a new behavioral test that would evaluate impulsivity in the most validated animal model of ADHD of the Spontaneously Hypertensive rat (SHR) as compared with the normotensive "control" strain, the Wistar Kyoto rat (WKY). In this paradigm we call the Electro-Foot Shock aversive water Drinking test (EFSDT), water-deprived rats should pass over an electrified quadrant of the EFSDT apparatus to drink water. We reasoned that impulsive animals show increased frequency to drink water even with the presentation of an aversive consequence (electro-shock). Through this assay, we showed that the SHR was more impulsive than the WKY as it demonstrated more "drinking attempts" and drinking frequency. Methylphenidate, the most widely used ADHD medication, significantly reduced drinking frequency of both SHR and WKY in the EFSDT. Thus, the present assay may be considered as another behavioral tool to measure impulsivity in animal disease models, especially in the context of ADHD.
