Differences in the relationship between traumatic experiences, self-esteem, negative cognition, and Internet addiction symptoms among North Korean adolescent defectors and South Korean adolescents: A preliminary study

Relationship Between Stressful Life Events and Online Deviant Behaviors Among College Students: A Moderated Mediation Model

With the gradual penetration of the Internet into the study and life of college students, the Internet not only brings convenience to young adults but also becomes a new channel for them to engage in deviant behaviors. This study explores the relationship between stressful life events and college students' online deviant behaviors, as well as the mediating role of negative automatic thoughts and the moderating role of perceived social support. Data is drawn from 448 college students (Mage = 20.10, SDage = 1.74). Results showed that stressful life events were significantly positively correlated with online deviant behaviors, and negative automatic thoughts mediated the relationship between stressful life events and online deviant behaviors. The relationship between stressful life events and online deviant behaviors, as well as that between negative automatic thoughts and online deviant behaviors, were both moderated by perceived social support. This study provides a practical guiding value for effectively preventing and intervening in college students' online deviant behaviors and maintaining the regular order of the online society.

The association between childhood maltreatment and internet addiction among Chinese junior middle school students: prospective cohort study

BACKGROUND

Childhood maltreatment is associated with internet addiction, but most evidence is from retrospective studies.

AIMS

We aimed to investigate the relationship between childhood maltreatment and internet addiction through a prospective cohort design.

METHOD

In a prospective cohort study, self-reported data on childhood maltreatment (Childhood Trauma Questionnaire - Short Form) at baseline, and internet addiction (Revised Chinese Internet Addiction Scale) at baseline and 6-month follow-up, were collected online from 756 Chinese junior middle school students aged 11-15 years and residing in Changsha, Hunan Province. Demographic data and covariates such as depression, anxiety, stress (Depression, Anxiety, and Stress Scale 21) and insomnia (Athens Insomnia Scale) were also surveyed at baseline. Logistic regression analysis measured the association between childhood maltreatment and internet addiction, and gender-related differences.

RESULTS

Childhood maltreatment was prevalent in Chinese junior middle school students (37.83%), and the incidence rate of internet addiction was 9.26% at the 6-month follow-up. Emotional abuse was a significant risk factor for internet addiction (adjusted odds ratio 2.618, 95% CI 1.194-5.738; P = 0.016) in both males and females.

CONCLUSIONS

This study suggests a high prevalence of childhood maltreatment in Chinese junior middle school students, and that emotional abuse plays a significant role in internet addiction. More attention should be paid to parenting style and adolescents' mental health.

Adolescent psychiatry of Y. Kasahara and succeeding research on Hikikomori in Europe and in Japan

This paper will focus on the works of one of Japan's representative psychiatrists, Yomishi Kasahara, particularly on his works in the 1970s in which he proposed the concept of student apathy, and will discuss how this work was carried over into a contemporary topic, the study of "Hikikomori." Kasahara's well-known paper "Clinical Classification of Depression" (Kasahara and Kimura, 1975) described the present state of patients with Type III as "they do not have a complete set of symptoms as in Type I, but sometimes show dependency, strong exaggeration, complication of other neurotic symptoms, little tendency of self-reproaching, and tendency of accusing others"; the two subtypes as Type III-1 "those that remain at the neurotic level" and Type III-2 "those that transiently drop to the psychotic level." We have summarized and introduced below the case presented in the paper with this Type III-1. From today's perspective, where the concept of "Hikikomori" exists, this case could be considered as a typical case of "Hikikomori," that is, a person with a tendency to avoid social roles and responsibilities and to immerse oneself in areas with no responsibilities, such as hobbies. "Hikikomori" was discovered in the late 1980s, but to be precise, it was just that the concept emerged. The same clinical condition had already been brilliantly found by Kasahara in the 1970s under the concept of "apathy syndrome," which was distinguished from depression.

The association of childhood maltreatment with Internet addiction: the serial mediating effects of cognitive emotion regulation strategies and depression

OBJECTIVES

Childhood maltreatment, cognitive emotion regulation strategies (CERSs), and depression can be important in adolescents' Internet addiction. The current study aims to investigate the direct effect of childhood maltreatment on Internet addiction and its indirect effects via CERSs and depression.

PARTICIPANTS AND SETTING

4091 adolescents (age M = 13.64, SD = 1.59; 48.9 % males) were recruited from a public school in China.

METHODS

In a cross-sectional design, participants completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Cognitive Emotion Regulation Questionnaire-Short version (CERQ-Short), the Self-Rating Depression Scale (SDS), and the Internet Addiction Test (IAT). A latent structural equation model was used to test the hypotheses.

RESULTS

After controlling for age, childhood maltreatment was directly associated with adolescents' Internet addiction (β = 0.12, p < 0.001). Meanwhile, the serial mediating effect via maladaptive CERSs and depression was 0.02 (95 % CI [0.01, 0.04]), and via adaptive CERSs and depression was 0.001 (95 % CI [0.0004, 0.002]), demonstrating significant serial mediating role of CERSs and depression in this relationship. No gender difference was observed.

CONCLUSIONS

The findings suggest that maladaptive CERSs and depression can be potential mechanisms relating childhood maltreatment to adolescents' Internet addiction, while adaptive CERSs can be a less influential factor for reducing Internet addiction.

Childhood Maltreatment, Automatic Negative Thoughts, and Resilience: The Protective Roles of Culture and Genes

Resilience, a psychological trait conceptualized as the ability to recover from setbacks, can be weakened by childhood maltreatment, which comprises childhood abuse and childhood neglect. The current study aimed to investigate whether childhood maltreatment could increase automatic negative thoughts (ANT), thus weakening resilience. Furthermore, as psychological characteristics are commonly subject to the moderating effects of cultural context and biology, the study also explored whether and how cultural and genetic factors separately interact with childhood maltreatment to predict resilience. In study 1, the participants comprised 237 American and 347 Chinese individuals; study 2 included 428 genotyped Chinese individuals. We combined regression, mediation, moderation, and machine learning methods to test the mediating effect of ANT on the link between childhood maltreatment and resilience as well as the moderating roles of culture and genetics. Study 1 found that both childhood abuse and childhood neglect increased ANT and thus weakened resilience. In addition, the ANT-mediating effects of childhood neglect were stronger in American than Chinese participants. In Study 2, using the leave-one-out approach, we constructed two separate prediction models based on 22 and 16 important single nucleotide polymorphisms (SNPs), and we found that the interaction between childhood abuse/neglect and polygenic scores based on important SNPs could predict ANT. The mediating effects of ANT on the relationship between childhood abuse/neglect and resilience were significant for participants with low polygenic scores but not for those with high polygenic scores. In conclusion, both the cultural environment and individual genetic makeup moderated the mediating effects of ANT on the association between childhood maltreatment and resilience. These findings indicated the roles of culture and genetics in protecting against the adverse effects of childhood maltreatment on resilience.

Reciprocal Prediction between Impulsivity and Problematic Internet Use among North Korean Refugee Youths in South Korea by Gender and Adverse Childhood Experience

OBJECTIVE

North Korean refugee youths are at higher risk of developing a wide array of psychosocial sequelae, including increased impulsivity and problematic internet use. We aimed to identify reciprocal temporal relationships by performing autoregressive cross-lagged modeling and to examine how these relations differ by gender and adverse childhood experience.

METHODS

We used the follow-up data of 108 North Korean refugee youths in South Korea over a 1-year period. The Barratt Impulsivity Scale-Brief and Young's Internet Addiction Test were used to assess impulsivity and problematic internet use, respectively.

RESULTS

Autoregressive effects were significant across all groups, indicating that impulsivity and problematic internet use were stable across time; however, prospective prediction of problematic internet use from impulsivity was not significant across all groups. Problematic internet use at baseline positively predicted impulsivity at after 1 year of follow up in only males and individuals with adverse childhood experience.

CONCLUSION

Our findings suggest that the negative effect of problematic internet use (i.e., increased impulsivity) among North Korean refugee youths may be more profound in males and those with adverse childhood experience. We present possible explanations for these findings and discuss the implications for targeted interventions.

Association of harsh parenting and maltreatment with internet addiction, and the mediating role of bullying and social support

Growing evidence has shown that exposure to harsh parenting and child maltreatment elevate the risk of Internet addiction in adolescence. Yet, limited research has examined the mechanisms underlying this association. The present study was a cross-sectional school survey of 1204 adolescents (52.2 % male and 47.8 % female; mean age, 13.36 years) in Hong Kong. The adolescents completed a self-reported questionnaire about their exposure to bullying victimization, bullying perpetration, child maltreatment, Internet addiction, and social support. The findings showed that harsh parenting and maltreatment was significantly associated with Internet addiction. After controlling for a number of confounding factors, the results of the mediation analyses showed that family support and bullying perpetration, and family support and bullying victimization accounted for 36 % and 25 % of the effect of harsh discipline and maltreatment on Internet addiction, respectively. Effective prevention and intervention strategies for Internet addiction should target family and social vulnerabilities in adolescents.

Prevalence and Risk Factors of Problematic Internet Use and Its Relationships to the Self-Esteem and Health-Related Quality of Life: Data From a High-School Survey in Giresun Province, Turkey

PURPOSE

This study aimed to investigate the prevalence of problematic internet use (PIU) among high school students, to evaluate its potential risk factors, and to investigate its relation to self-esteem and health-related quality of life.

METHODS

This cross-sectional study included 1,558 high school students in Turkey. Participants completed the Internet Addiction Test as well as the Rosenberg Self-Esteem Scale and 12-item Short Form Health Survey. Demographics and internet usage patterns were also collected. Data analysis was conducted by descriptive and analytical statistics (Pearson chi-square tests, independent-samples t test, and binary logistic regression).

RESULTS

The mean age of the participants was 16.20 ± 1.05 years. Nearly 21.1% of the participants exhibited PIU (Internet Addiction Test score ≥ 50). The findings indicated that PIU was associated with poor self-esteem and poor physical and mental health. The PIU was significantly higher among students using the internet for social networking. The chi-square analysis showed a significant correlation between the severities of PIU and the students' type of school, residence, perceived academic performance, and relationship with parents (p < .05). No significant correlation was found between PIU severity and age group, gender, number of siblings, paternal or maternal educational levels, self-reported family income, sleep duration, or whether or not they resided with parents (p > .05).

CONCLUSIONS

PIU was found to be a common problem among high school students, and it was significantly correlated with self-esteem and health-related quality of life. To alleviate this public health problem, at-risk groups should be identified and timely management strategies and effective prevention programs should be established.

An exploration of the associations among positivity, general distress and internet addiction: The mediating effect of general distress

The aim of the present study was to examine the relationships between positivity and general distress (including depression, anxiety, stress) and internet addiction and the mediating effects of general distress. The theoretical model was examined with 392 volunteers who were university students. Participants filled out the Positivity Scale (POS), Depression, Anxiety, Stress Scale (DASS) and Short Form of Young's Internet Addiction Test (YIAT-SF). The results revealed that there were significant associations among positivity, general distress and internet addiction. According to the results of mediation analysis using structural equation modelling and bootstrapping, depression fully mediated the positivity-internet addiction relationship, whilst anxiety and stress partially mediated it. Bootstrap analysis indicated that positivity exerted a significant indirect effect on internet addiction through depression. Overall, the results implied the potential therapeutic effect of positivity which leads to a direct decrease in general distress and an indirect decrease in internet addiction through general distress. In addition, internet addiction may be considered as a secondary problem rather than a primary disorder. The results provide opportunities to design psychological interventions focused on improving positivity which may lead to a decrease in general distress which involves a mechanism preventing individuals from applying a positive reinforcement process.

Health risk behaviors and psychological problems among South Korean, North Korean, and other multicultural family adolescents (2011-2016)

This study was aimed to investigate the health risk behaviors and psychological problems among North Korean, other multicultural, and South Korean family adolescents. The data were collected from the Korea Youth Risk Behavior web-based survey (2011-2016) data set. A total of 17,195 adolescents (mean age 14.65 ± 0.01 years) were analyzed to compare health risk behaviors and psychological problems among the three groups. Concerning risk behaviors, multicultural family adolescents showed a higher rate of alcohol use, smoking, drug use and sexual relations compared to South Korean family adolescents. Moreover, North Korean family adolescents were more likely to experience those risk behaviors than other multicultural family adolescents. Concerning psychological problems, multicultural family youth displayed more depressed mood, and more suicidal ideation, planning, and attempts when compared with South Korean family youth. Among multicultural families, North Korean family adolescents were more depressed and showed higher suicidality. School-based education and preventive interventions are necessary to manage risk behaviors and psychological difficulties of adolescents in North Korean and other multicultural families.

Prediction of internet addiction based on information literacy among students of Iran University of Medical Sciences

Background

A considerable group of internet users consists of university users; however, despite internet benefits and capabilities, internet overuse is a threat to societies especially to young people and students.

Objective

The objective of this study was to determine the predictive role of information literacy in internet addiction among students of Iran University of Medical Sciences during 2016.

Methods

This analytical cross-sectional study was conducted in Iran University of Medical Sciences in 2016. Using stratified random sampling method, 365 students from different disciplines were selected. Measuring tools included the Information Literacy Questionnaire, the Yang Online Drug Addiction Scale and the General Health Questionnaire. The collected data were analyzed by Pearson product-moment correlation, independent samples t-test and multiple linear regression using SPSS version 22.

Results

According to this study, 31.2% of students had internet addiction (29.9% were mildly addicted and 1.3% had severe addiction). There was a significant and inverse relationship between higher information literacy and internet addiction (R= −0.45) and (p<0.001). The predictor variable “Information literacy” explained 20% of the variation in the outcome variable “Internet addiction”.

Conclusion

Students play a substantial role in promoting the cultural and scientific level of knowledge in society; the higher their information literacy, the lower the level of Internet addiction, and consequently the general health of society will improve. It seems that wise planning by authorities of Iran’s universities to prevent internet addiction and to increase information literacy among students is needed.
