Hong Youl Pyo,Yeom Yeon Ok,Lim Myung Ho 대한의학회 2021 Journal of Korean medical science Vol.36 No.19

Background: The purpose of this study was to examine the relationships between smartphone addiction of middle school students and smartphone usage types, depression, attention deficit hyperactivity disorder (ADHD), stress, interpersonal problems, and parenting attitude. In particular, we wanted to find out how smartphone usage types predict smartphone addiction when controlling depression, ADHD, perceived stress, interpersonal problems, and parenting attitudes, which are the main predictors of existing smartphone addiction in this study. Methods: The subjects of this study included 487 local middle school students (253 girls and 234 boys). The measurement instruments used were the smartphone addiction scale, patient health questionnaire-9 (PHQ-9), Korean ADHD rating scales (K-ARS), perceived stress scale (PSS), Short form of the Korean-inventory of interpersonal problems circumplex scales (KIIP-SC), and the parenting attitude scale. We identified the relationships between the variables with correlation analysis and examined the predictors of smartphone addiction with hierarchical multiple regression analysis. Result: The factors that influence smartphone addiction were sex (β = 3.14, P < 0.01), stress (β = 2.99, P < 0.01), and interpersonal problems (β = 3.81, P < 0.001). In addition, when the confounding variables of smartphone addiction were controlled to examine the effects of smartphone usage types on smartphone addiction, social network service (SNS) (β = 2.66, P < 0.01) and music/videos (β = 2.73, P < 0.01) were found to significantly positively affect smartphone addiction, whereas study (β = −2.54, P < 0.05) had a significantly negatively effect. And these factors explained 29.5% of the variance in smartphone addiction. Conclusion: The order of the usage types with the highest influence on smartphone addiction was: enjoying music/videos, SNS, and study. This suggests that selective intervention depending on the main smartphone usage type can be effective.

Lee, Hyuk,Kim, Jun Won,Choi, Tae Young The Korean Academy of Medical Sciences 2017 Journal of Korean medical science Vol.32 No.10

<P>With widespread use of the smartphone, clinical evidence for smartphone addiction remains unclear. Against this background, we analyzed the effect of smartphone use patterns on smartphone addiction in Korean adolescents. A total of 370 middle school students participated. The severity of smartphone addiction was measured through clinical interviews and the Korean Smartphone Addiction Proneness Scale. As a result, 50 (13.5%) were in the smartphone addiction group and 320 (86.5%) were in the healthy group. To investigate the effect of smartphone use patterns on smartphone addiction, we performed self-report questionnaires that assessed the following items: smartphone functions mostly used, purpose of use, problematic use, and parental attitude regarding smartphone use. For smartphone functions mostly used, the addiction group showed significantly higher scores in “Online chat.” For the purpose of use, the addiction group showed significantly higher “habitual use,” “pleasure,” “communication,” “games,” “stress relief,” “ubiquitous trait,” and “not to be left out.” For problematic use, the addiction group showed significantly higher scores on “preoccupation,” “tolerance,” “lack of control,” “withdrawal,” “mood modification,” “conflict,” “lies,” “excessive use,” and “loss of interest.” For parental attitude regarding children's smartphone use, the addiction group showed significantly higher scores in “parental punishment.” Binary logistic regression analysis indicated that “female,” “use for learning,” “use for ubiquitous trait,” “preoccupation,” and “conflict” were significantly correlated with smartphone addiction. This study demonstrated that the risk factors for smartphone addiction were being female, preoccupation, conflict, and use for ubiquitous trait; the protective factor was use for learning. Future studies will be required to reveal the additional clinical evidence of the disease entity for smartphone addiction.</P>

Objectives:Recently, adolescent use of smartphones has dramatically increased. Consequently, smartphone addiction has emerged as a serious social problem. Researches on internet and cellular phone addiction have reported correlation between such addictions and symptoms such as depression and social anxiety. However, there have only been limited studies on the relationship between smartphone use, depression and social anxiety. Methods:Subjects involved in this study are 57 high school students and 16 patients who are diagnosed with depressive disorder in a university hospital and are currently being treated on visitation basis. In order to measure smartphone addiction, this research used Smartphone Addiction Proneness Scale(SAPS) developed by Korea National Information Society Agency in 2011. In order to measure depression and social anxiety, Beck Depression Inventory(BDI) and Fear of Negative Evaluation(KFNE) were used respectively. Results:The prevalence of smartphone addiction was 24.7%. The BDI and KFNE scores for the smartphone-addicted group were significantly higher than subjects who are not addicted to smartphone use. The percentage of women in the smartphone-addicted group was meaningfully higher than that in the non-addicted group. Although there was an overall meaningful correlation between smartphone addiction, BDI and KFNE, when considered in the context of gender, only females showed a meaningful correlation between smartphone addiction, BDI, and KFNE. Conclusion:Depression and social anxiety are meaningfully correlated to smartphone addiction. Women have shown a strong correlation between social anxiety and smartphone addiction. This may suggest that women tend to cope with their emotional problems caused by their interpersonal relationships through use of information technologies that enable them to access the virtual world. This research also shows that it may be beneficial to treat patients with both smartphone addiction and depression, social anxiety on an individualized basis.

The purpose of this study was to provide the basic data necessary for research aimed at preventing the issues of smartphone addiction and depression in college students, who are very likely to have a smartphone, as the rate of using smartphones is on the rapid increase. For this purpose, a survey was conducted on smartphone addiction and depression by using a self-administered questionnaire in college students in rural communities from May to June 2019; then, 928 copies were analyzed, with the exception of incomplete ones and those with uncertain or ambiguous answers. The questionnaire covered the general characteristics of both smartphone addiction and depression. Exploratory factor analysis using correlation matrix and principal factor analysis was performed to validate the instrument and Cronbach’s α was estimated to determine its reliability. Smartphone addiction is found to account for 58.302% of all smartphone addiction with two multi-dimensional subconcepts, factor 1 for daily life disorders and factor 2 for 67.016% for all depression with two multi-dimensional subconcepts and anxiety. Confidence in smartphone addiction and depression is Cronbach’s α=.891~943, Cronbach’s α=.911~960. The gender distribution was somewhat male, the first grade was the most common by grade and the satisfaction level of school life was the most common. As for smartphone addiction, men were more likely to have daily living disorders, abnormal flow, and overall smartphone addiction than women. The respondents highly dissatisfied with school life were more likely to have daily living disorders than those satisfied or highly satisfied with school life; the respondents dissatisfied with school life were more likely to have daily living disorders than those highly satisfied with school life. The respondents dissatisfied or highly dissatisfied with school life were more likely to show abnormal flow than those highly satisfied with school life; the respondents dissatisfied or highly dissatisfied with school life or at the average level of school life satisfaction were more likely to have overall smartphone addiction than those highly satisfied with school life. In terms of major, colleges of physical education and art and engineering were more likely to show daily living disorders, abnormal flow, and overall smartphone addiction than those of applied life sciences. In terms of depression, impatience differed significantly by school year: seniors were more impatient than juniors. The respondents highly dissatisfied with school life were more likely to have negative thinking and overall depression than those dissatisfied with school life; the respondents dissatisfied with school life were more likely to do so than those satisfied or highly satisfied with school life or at the average level of school life satisfaction. The respondents highly dissatisfied with school life were more likely to be impatient than those dissatisfied, satisfied, or highly satisfied with school life or at the average level of school life satisfaction; the respondents dissatisfied with school life were more likely to be impatient than those highly satisfied with school life. As for the effects of the sub-factors for smartphone addiction on depression, the lower the level of abnormal flow, the more depressed the respondent. On the basis of these results, it is necessary to make concerted interventions to relieve the depressed mood and increase happiness among college students, make efforts to promote their self-esteem, and develop based plans for them to feel happy and possess hope for the future with the objective of preventing smartphone addiction.

Objectives The purpose of this study was to investigate the effect of smartphone addiction of parents with elementary school children on marital conflict and to explore the structural relationships among smartphone addiction of parents, marital conflict, parental involvement, and media device addiction of their children who go to elementary school. Methods A total of 1,224 pairs of data from the 13th Korean Children's Panel Study (2020) were analyzed with Actor-Partner Interdependence Model (APIM). In order to compare the actor and the partner effect of smartphone addiction, an equivalence constraint model was set up and difference verification was conducted. Also, a structural equation analysis method based on the maximum likelihood method (ML) was used to verify the structural relationship among parental smartphone addiction, marital conflict, parental involvement, and elementary school students' addiction to media devices. Results The results are as follows: first, both mother’s and father’s smartphone addiction had a positive actor effect on the marital conflict, but a positive partner effect was only confirmed from mother’s smartphone addiction. Second, the actor effect of smartphone addiction on marital conflict was found to be greater in father than mother, however, the partner effect of father's smartphone addiction on marital conflict perceived by mother was greater than the partner effect of mother's smartphone addiction on marital conflict perceived by father. Third, mother's smartphone addiction was influenced through how she perceived marital conflict and parental involvement on students' media device addiction, while father's smartphone addiction was influenced sequentially by mother's perceived marital conflict and parental involvement on students' media device addiction. Conclusions This study suggests that both mother and father's smartphone addiction affect to elementary school students' media device addiction, but the mechanisms affecting on media device addiction from parents are different.

본 연구는 어머니의 스마트폰 중독과 청소년의 스마트폰 중독 간 관계에서 부정적 양육태도, 청소년의 사회적 위축과 우울의 다중매개효과를 살펴보기 위해 수행되었다. 이를 위해 한국아동·청소년패널조사(KCYPS) 2018 중1패널 데이터의 1차년도 자료를 활용하여 분석하였다. 연구결과 첫째, 어머니 스마트폰중독은 부정적 양육태도와 청소년의 스마트폰 중독에 영향을 미치고, 부정적 양육태도는 청소년의 사회적 위축과 우울 및 청소년 스마트폰 중독에 유의한 영향을 미치는 것으로 나타났다. 또한, 청소년의 사회적 위축은 우울과 스마트폰 중독에 영향을 미치며, 우울은 청소년의 스마트폰 중독에 유의미한 영향을 미치는 것으로 나타났다. 둘째, 매개모형 검증 결과, 특히 어머니 스마트폰 중독과 청소년의 스마트폰 중독의 관계에서 부정적 양육태도의 부분 매개효과가 유의하였으며, 부정적 양육태도와 청소년 사회적 위축의 순차적 매개효과가 유의한 것으로 나타났다. 뿐만 아니라, 어머니 스마트폰 중독과 청소년의 스마트폰 중독의 관계에서 부정적 양육태도와 청소년 우울의 순차적 매개효과가 유의하였으며, 부정적 양육태도와 청소년 사회적 위축 및 우울의 순차적 매개효과가 유의한 것으로 나타났다. 마지막으로, 다집단 동등성 검증 결과, 모든 경로에서 경로동일성이 확보되었으나, 부정적 양육태도에서 우울에 이르는 경로, 사회적 위축에서 우울에 이르는 경로, 사회적 위축에서 청소년 스마트폰 중독에 이르는 경로, 우울에서 청소년 스마트폰중독에 이르는 경로에서 남녀 집단 간 유의한 차이를 보였다. 본 연구는 어머니의 스마트폰 중독, 부정적 양육태도, 청소년의 사회적 위축, 우울 및 청소년의 스마트폰 중독 간 구조적 관계에서 특히 청소년의 스마트폰 중독에 영향을 미치는 가정환경적 변인과 심리사회적 변인을 확인함으로써 청소년의 스마트폰 중독에 대한 개입의 방안으로서 위험요인과 보호요인에 대한 통합적 접근 방안을 마련하였다는 점에서 의의가 크다. 마지막으로 본 연구의 시사점과 제한점이 논의되었다. The purpose of this study is to examine the multiple mediating effects of negative parenting attitude, social withdrawal and depression of adolescents in the relationship between mother’s smartphone addiction and adolescents’ smartphone addiction. To this end, the data for the first year of KCYPS2018 data were used to analyze. The research results are as follows. First, it was found that the mother’s smartphone addiction had an effect on the negative parenting attitude and the smartphone addiction of the adolescent, and the negative parenting attitude had a significant effect on the adolescent’s social withdrawal, depression and smartphone addiction. In addition, social withdrawal of adolescents has an effect on depression and smartphone addiction, and depression has a significant effect on adolescents’ smartphone addiction. Second, the mediated model verification results are as follows. First, in the relationship between mother’s smartphone addiction and adolescents’ smartphone addiction, the partial mediating effect of negative parenting attitude was significant, and the sequential mediating effect of negative parenting attitude and adolescents’ social withdrawal was significant. Next, in the relationship between mother’s smartphone addiction and adolescents’ smartphone addiction, the sequential mediating effect of negative parenting attitude and adolescent depression were significant, and the sequential mediating effect of the negative parenting attitude, adolescents’ social withdrawal and depression were significant. Finally, as a result of multi-group equivalence verification, path homogeneity was secured in all paths. However, there were significant differences between male and female groups in the path from negative parenting attitude to depression, social withdrawal to depression, social withdrawal to adolescents’ smartphone addiction, and depression to adolescents’ smartphone addiction. This study examines the structural relationships among mothers’ smartphone addiction, negative parenting attitudes, adolescents’ social withdrawal, depression, and adolescents’ smartphone addiction. It is significant in that it has prepared an integrated approach to risk factors and protection factors as a method of intervention for adolescents’ smartphone addiction. Finally, the implications and limitations of this study were discussed.
