PURPOSE: The purpose of this study was to examine the degrees of cellular phone usage among middle school students and to identify discriminating factors of addictive use of cellular phones among sociodemographic and psychological variables. METHODS: From 123 middle schools in Busan, potential participants were identified through stratified random sampling and 747 middle school students participated in the study. The data was collected from December 1, 2004 to December 30, 2004. Descriptive and discriminant analyses were used. RESULTS: Fifty seven percent of the participants were male and 89.7% used cellular phones at school. The participants were grouped into three groups depending on the levels of the cellular phone usage: addicted (n=117), dependent (n=418), non-addicted (n=212). Within the three groups, two functions were produced and only one function was significant, discriminating the addiction group from non-addiction group. Additional discriminant analysis with only two groups produced one function that classified 81.2% of the participants correctly into the two groups. Impulsiveness, anxiety, and stress were significant discriminating factors. CONCLUSION: Based on the findings of this study, developing intervention programs focusing on impulsiveness, anxiety and stress to reduce the possible addictive use of cellular phones is suggested.

OBJECTIVE: We investigated the prevalence of obsessive compulsive disorder (OCD) among patients with schizophrenia, as well as the differences in psychotic symptoms and suicidality between schizophrenia patients with and without OCD. METHODS: Seventy-one subjects with the DSM-IV diagnosis of schizophrenia were evaluated by the Structured Clinical Interview for DSM-IV Axis I disorders, the Yale-Brown Obsessive-compulsive Scale and the Positive and Negative Syndrome Scale. RESULTS: There were 20 (28.2%) OCD patients with schizophrenia among the 71 subjects, and these 20 had significantly more severe negative and total psychotic symptoms than the 51 subjects without OCD, as evaluated with PANSS. The schizophrenia subjects with OCD had a significantly higher, recent suicidal attempt rate than those without OCD. CONCLUSION: The results of this study suggest the possibility that OCD symptoms in schizophrenia may be related to negative symptoms and that the OC symptoms may be related to the impulsivity expressed as suicidal attempts.

The purpose of this research was to study the relationship of academic achievement and impulsivity in children with learning disorders with parenting strain and self-competence of their mothers. A sample of 70 students with learning disorders along with their mothers was recruited for the study. Data were collected using the UPPS Impulsive Behavior Scale, a modifi ed version of Zarit Burden Interview, Parent Sense of Competence Scale and each student’s grade point average as an index of academic achievement. Data were analyzed using Pearson’s correlation coeffi cients and multiple regression analysis. Findings revealed that academic achievement correlates signifi cantly and positively with mothers’ sense of competence but negatively with their experience of parenting strain. Furthermore, children’s impulsivity was negatively associated with mothers’ sense of competence but showed no relationship to parenting strain. Regression analysis indicated that while children’s impulsivity predicted mothers’ sense of competence but not their parenting strain, children’s academic achievement predicted both. Findings imply that when children with learning disorders are highly impulsive, their mothers only report an incapability to cope with stress. But when children’s academic achievement is low, mothers tend to not only experience increasing parenting stress but also report feeling overwhelmed by the stress. Findings imply that features of children with learning disorders have a differential impact on the mental health of their mothers.

PURPOSE: This study was done to develop a cell phone addiction scale for Korean adolescents. METHODS: The process included construction of a conceptual framework, generation of initial items, verification of content validity, selection of secondary items, preliminary study, and extraction of final items. The participants were 577 adolescents in two middle schools and three high schools. Item analysis, factor analysis, criterion related validity, and internal consistency were used to analyze the data. RESULTS: Twenty items were selected for the final scale, and categorized into 3 factors explaining 55.45% of total variance. The factors were labeled as withdrawal/tolerance (7 items), life dysfunction (6 items), and compulsion/persistence (7 items). The scores for the scale were significantly correlated with self-control, impulsiveness, and cell phone use. Cronbach's alpha coefficient for the 20 items was .92. Scale scores identified students as cell phone addicted, heavy users, or average users. CONCLUSION: The above findings indicate that the cell phone addiction scale has good validity and reliability when used with Korean adolescents.

OBJECTIVES: The aim of this study was to examine the effect of depression, impulsivity, and resilience on smartphone addiction in university students. METHODS: A total of 322 students from two universities in Seoul were enrolled in this study. Participants were divided into a risk user group and normal user group according to results using the Korean smartphone addiction scale. We additionally surveyed smartphone use patterns of the participants. The Beck Depression Inventory (BDI), Barratt Impulsiveness Scale (BIS), and Conner-Davidson Resilience Scale (CD-RS) were also used for measurement of the participants' severity of depression, impulsivity, and resilience. RESULTS: The risk user group spent more time using a smartphone on weekdays than the normal user group. The risk user group showed significantly higher scores on BDI, BIS than the normal user group. The risk user group showed significantly lower scores on CD-RS than the normal user group. Results of multiple regression analysis showed that impulsivity was a significant factor affecting smartphone addiction in university students. CONCLUSION: These results suggest that smartphone addiction is influenced by impulsivity. Students with high impulsivity may be vulnerable to smartphone addiction. Further research regarding the underlying mechanisms of these associations is needed.

Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disorder that can affect individuals across their lifespan. It is characterized by the core symptoms of inattention, impulsivity and hyperactivity. ADHD develops as a result of the complex interplay between genetic and environmental factors. Children and adults with ADHD usually suffer concomitantly from other psychiatric comorbidities, including both externalizing and internalizing disorders. It is associated with functional impairment and poor long-term outcomes. This review aims to summarize the key findings from recent research into ADHD and its prevalence, core symptoms, cause and comorbidities from childhood to adulthood.

Secondary mania is closely linked to neurocircuitry defects. Frontal-subcortical circuits, in particular, play a major role in the affective, motor and cognitive symptoms of secondary mania. In this paper, we present the three main frontal-subcortical circuits : the dorsolateral prefrontal circuit, which mediates executive functions (i.e., the organization of information to facilitate a response) ; the anterior cingulate circuit, which is involved in motivated behavior ; the orbitofrontal circuit, which has medial (i.e., integration of visceral-amygdalar functions with the internal state of the organism) and lateral divisions (i.e., integration of limbic and emotional information into contextually appropriate behavioral responses). Impaired executive functions, apathy, disinhibition and impulsivity are hallmarks of frontal-subcortical circuit dysfunction. The various neuropsychiatric manifestations of secondary mania may result from disturbances that have a direct or indirect impact on the integrity or functioning of these loops.

PURPOSE: The purpose of this study was to examine impulsivity and self-efficacy according to Internet addiction in adolescents. METHOD: Subjects were middle and high school students in Daegu (N=486). Data were collected by a self-rating questionnaire including demographic data, a Korean version of Internet addiction, impulsivity and self-efficacy. RESULT: Impulsivity and self-efficacy according to Internet addition were significantly different (F=22.909, p<.001). There were significant correlations between Internet addiction and impulsivity (r=.280, p<.01), between Internet addiction and self-efficacy(r=-.288, p<.01) and between impulsivity and self-efficacy (r=-.665, p<.01). CONCLUSION: These results indicate that the more addictive to the Internet the more impulsive and the less self-efficacious. Therefore, further studies are needed to generalize these results and examine the effects of Internet addiction more broadly.
