The Relationship Between Perceived Stress and Smartphone Addiction: The Mediating Effect of Rumination and The Mediated Moderating Effect of Mindfulness.

OBJECTIVE: This study was to examine the mediated moderation effect of mindfulness through rumination on the relationship between perceived stress and smartphone addiction. In particular, this study examined the moderating effect of mindfulness in detail by dividing it into five sub-factors. METHODS: An online self-report questionnaires were conducted on 697 participants aged 20 to 59. Finally, 681 participants (male=356, female=325) were included final analysis. Moderating effect, mediated moderating effect were verified using PROCESS macro for SPSS v3.5. RESULTS: First, perceived stress was positively related to smartphone addiction. Second, rumination mediated the relationship between perceived stress and smartphone addiction. Third, acting with awareness and nonjudging of experience, which are a sub-factor of mindfulness, moderated the relationship between perceived stress and smartphone addiction. Fourth, mindfulness facets (acting with awareness and nonjudging of experience) moderated the relationship between rumination and smartphone addiction. Finally, there was a mediated moderating effect of mindfulness facets (acting with awareness and nonjudging of experience) on the relationship between perceived stress and smartphone addiction through rumination. CONCLUSION: This research suggests the useful and specific therapeutic interventions that help lower the level of the adults' addiction on smartphones.

The Association between Adverse Childhood and Adulthood Experiences, Social Isolation, Loneliness, and Depression among Young Adults in South Korea.

This study examined the association between social isolation, loneliness, and depressive symptoms among young adults in South Korea after controlling for sociodemographic variables, adverse child and adult experiences, and perceived health status. The researcher analyzed the data of 2014 young adults aged 18-34 years from the Youth Social Economic Survey using hierarchical multiple regression analysis conducted with IBM SPSS Statistics 28.0. Among the sociodemographic variables, sex, education, and household income were significantly related to depressive symptoms. Females reported higher levels of depressive symptoms than males, and those attending college or having a college (or higher) degree reported lower levels of depressive symptoms than those with a high-school diploma or lower. Higher household income was associated with lower levels of depressive symptoms. Perceived health status was negatively associated with depressive symptoms, while adverse childhood and adulthood experiences, social isolation, and loneliness were positively associated with it. Among the major independent variables, loneliness was most strongly related to depressive symptoms, whereas social isolation had the weakest relevance to it. The prediction model proposed explained 32.7% of the variance in depressive symptoms and was considered good. Therefore, focusing on loneliness may be more important than focusing on social isolation to prevent and deal with depressive symptoms among young adults.

Moderating Effects of Emotional Recognition Competency in Rejective Parenting and Adolescent Depression and Aggression.

Rejective parenting is a major antecedent of emotional instability and aggressive behavioral problems. Previous studies have reported that emotional problems, such as depression, anxiety, aggression, and conduct problems in children and adolescents, improve through interventions that enhance emotional recognition competency. In this study, we explored whether the emotional recognition ability levels of individual adolescents moderated the pathway of negative parenting on aggression mediated by depression The moderated mediating effect of emotional recognition competency was investigated through examining 2265 first-year high school students using the 2021 data from the Korean Children and Youth Panel Survey 2018. There was no significant moderating effect on the direct pathway from rejective parenting to aggression. The moderating effect of emotional recognition competency on the indirect pathway leading to aggression through depression in rejective parenting was significant. These results suggest that the ability to correctly understand signals related to the emotions of others can play an important role in reducing depression and aggressive behavior by reducing conflict with people around them and experiencing more support.

A Systematic Review of Location Data for Depression Prediction.

Depression contributes to a wide range of maladjustment problems. With the development of technology, objective measurement for behavior and functional indicators of depression has become possible through the passive sensing technology of digital devices. Focusing on location data, we systematically reviewed the relationship between depression and location data. We searched Scopus, PubMed, and Web of Science databases by combining terms related to passive sensing and location data with depression. Thirty-one studies were included in this review. Location data demonstrated promising predictive power for depression. Studies examining the relationship between individual location data variables and depression, homestay, entropy, and the normalized entropy variable of entropy dimension showed the most consistent and significant correlations. Furthermore, variables of distance, irregularity, and location showed significant associations in some studies. However, semantic location showed inconsistent results. This suggests that the process of geographical movement is more related to mood changes than to semantic location. Future research must converge across studies on location-data measurement methods.

The Relationship between Social Network Service Use Motives and Subjective Well-Being: The Mediating Effect of Online and Offline Social Capital.

OBJECTIVE: The purpose of this study was to examine the mediating effect of social capital on the relationship between Social Media use motives and subjective well-being. METHODS: In the study, online self-reporting surveys were conducted with Social Media users in their 20s, and data from 445 participants were used for structural equation modeling. RESULTS: The main findings of the study were as follows. First, the interpersonal motives for Social Media use had an indirect effect on subjective well-being by mediating offline bonding capital and online bonding capital. In addition, interpersonal motives had an indirect effect on subjective well-being by dual-mediating online and offline bonding capital. Second, the self-expression motive for Social Media use did not directly affect subjective well-being, but it indirectly affected subjective well-being by mediating offline bonding capital. Third, the information-seeking motive for Social Media use did not directly affect subjective well-being, but it indirectly affected subjective well-being by mediating offline bonding capital. CONCLUSION: This study identified a specific mechanism for how motives for using Social Media affect subjective well-being. Furthermore, the results of this study suggest that the effect of Social Media use on subjective well-being may differ depending on the motive for Social Media use.

The relationship between personality, social capital, and life satisfaction of elderly Koreans.

BACKGROUND: There are very few studies that explain the life satisfaction of the elderly by considering both internal factors such as personality and social capital. Therefore, this study analyzed the relationship between personality, social capital, and life satisfaction among elderly Koreans. METHODS: This study analyzed the survey data on Koreans' happiness and quality of life 2019. Participants included a total of 1280 elderly adults aged 60-79 years. RESULTS: A multiple hierarchical regression analysis indicated that higher health status was related to higher life satisfaction, while neuroticism was negatively related to life satisfaction. Of particular note, increased structural and cognitive social capital were associated with higher life satisfaction. However, income, financial problems, and extraversion were not related to life satisfaction. The total explanatory amount of the regression model was 38.5%. CONCLUSIONS: These findings suggest that researchers and clinicians should consider a combination of factors associated with both personality and social capital when aiming to improve life satisfaction for the elderly.

Impacts of Perceived Stress, Neglect, Victim and Respect for Human Rights on Depression of Adolescents.

The purpose of this study was to identify the impacts of perceived stress, neglect, online and offline violence, and respect for human rights on depression. To fulfill the purpose of the study, the data of 6277 middle and high school students (M = 15.64, SD = 1.69) from the Survey on the Human Rights of Children and Youth (2018) were used. The main results of the hierarchical multiple regression analysis are as follows. First, gender and age had significant impacts on depression. Second, neglect, perceived stress, and online violence were positively related to depression, whereas offline violence showed no relationship with depression. Third, respect for human rights, which is the final stage of the hierarchical multiple regression analysis, was negatively associated with depression. This study contributed to the research by verifying that perceived respect for human rights is a protective factor against depression.

The Effect of Social Isolation, Loneliness, and Physical Activity on Depressive Symptoms of Older Adults during COVID-19: A Moderated Mediation Analysis.

Depressive symptoms have been commonly reported in older adults during the coronavirus disease (COVID-19) pandemic. Social isolation as a result of social distancing to prevent COVID-19 was reported to increase the level of depressive symptoms both directly and indirectly through the mediating effect of loneliness. Depressive symptoms in older adults can be regulated through health behaviors such as physical activity. Therefore, this study used a moderated mediation model to explain depressive symptoms. The English Longitudinal Study of Ageing COVID-19 wave 2 data were used. A total of 296 individuals were excluded due to missing values, leaving a final sample of 6499. Depressive symptoms, social isolation, loneliness, and physical activity were used in the moderated mediation analysis with various demographic and general health variables as covariates. Loneliness was found to significantly mediate the relationship between social isolation and depression. While moderate physical activity significantly moderated the effects of social isolation and loneliness on depressive symptoms, mild physical activity alone significantly moderated the effects of loneliness on depressive symptoms. This study revealed the impact of social isolation on depressive symptoms directly and indirectly mediated by loneliness, with a moderating effect of moderate and mild physical activity in the elderly during COVID-19 in a moderated mediation model.

The Relationship between Smartphone Use Motives, Social Capital, Digital Literacy, and Life Satisfaction in Elderly Koreans.

Background: As the elderly population increases, interest in life satisfaction in old age is increasing. We aimed to verify the relationship between social capital, smartphone use motives, and digital literacy and life satisfaction in Koreans aged 50-69 yr. Methods: The data of 7,521 late-middle-aged and older adults from the 2019 survey on smartphone overdependence conducted by the National Information Society Agency were analyzed by hierarchical multi-regression analysis. Results: A hierarchical multiple regression analysis indicated that income(ß=0.062) and educational background(ß=0.054) were positively related to life satisfaction. Among the smartphone use motives, lifestyle motive(ß=-0.069) was negatively related to life satisfaction. Digital literacy(ß=0.145) and Social capital(ß=0.425) were positively related to life satisfaction. Conclusion: Digital literacy and social capital were positively associated with life satisfaction. In addition, this study considered the effects of lifestyle-based apps, while past studies only focused on communication- and leisure-based smartphone activities as factors influencing life satisfaction in adults in their 50s-60s. This study can provide a theoretical framework for therapeutic interventions to improve life satisfaction in the elderly.

The Relationship Between Parental Neglect, School Adjustment, and Smartphone Dependence in Korean Adolescents: Verification Using Multivariate Latent Growth Modeling.

The Social bonding theory assumes that social ties are closely associated with maladaptive behavior, and this theory may be applied to explain the smartphone dependence in adolescence. The purpose of this study was to verify how school adjustment mediated the relationship between the parental neglect and smartphone dependence. The data from Korean Children and Youth Panel Survey were utilized in this study. Participants were 2280 students in the 2nd year of middle school [male 1152, female 1128; 13.89 years (SD = 0.34)] who were followed up for four years. We conducted a Multivariate Latent Growth Modeling (LGM) to verify the relationships between variables. In addition, mediating effect was analyzed using the Bootstrapping Test. Findings indicated that parental neglect was negatively associated with school adjustment in the first wave, and school adjustment showed a greater decrease as parental neglect indicated a greater increase. In addition, school adjustment was negatively associated with smartphone dependence in the first wave, and smartphone dependence showed a greater decrease as school adjustment indicated a greater increase. Mediating effect indicated that parental neglect indirectly influences smartphone dependence fully mediating school adjustment. In conclusion, parental neglect indirectly influences smartphone dependence by interfering with school adjustment. In addition, reducing the negative effects of parental neglect on school adaptation may be an effective strategy to prevent smartphone dependence in adolescence.

OBJECTIVE: This study aimed to reveal the relationship between social capital, the happiness of others, and the happiness of Korean adults. METHODS: Data from 4,890 participants (2,092 males [42.78%] and 2,798 females [57.22%]) aged 19 to 79 years were used. Data used in the analysis were provided by the Survey on Koreans' Happiness and Quality of Life (2019) conducted by the Korea Institute for Health and Social Affairs. RESULTS: First, age, education, marital status, and subjective economic level were found to be significantly related to individual happiness. Second, social capital, which including trust and social participation, was positively related to individual happiness. Third, the key result of this study was that the happiness of close people was positively associated with individual happiness. Fourth, belonging showed a significant moderating effect on the relationship between the happiness of others and individual happiness. CONCLUSION: This study contributes by examining the relationship between the happiness of others and individual happiness after controlling for social capital and demographic variables and examining the moderating effect of social capital on the relationship between the happiness of self and others. These results are expected to help understand the factors that determine the happiness of Korean adults.

The Relationship Between Types of Smartphone Use, Digital Literacy, and Smartphone Addiction in the Elderly.

OBJECTIVE: There is limited understanding of which specific factors relate to smartphone addiction in the elderly. The aim of this study was to examine the relationship between types of smartphone use, digital literacy, and smartphone addiction in the elderly. METHODS: It used data from a survey on smartphone overdependence by the South Korea National Information Society Agency in 2019. Participants were 3,121 older people (1,627 males, 1,494 females; mean age=63.83 [standard deviation=2.88 years]). We conducted hierarchical multiple regression analysis. RESULTS: The results of a hierarchical multiple regression analysis indicated that smartphone usage time was positively related to smartphone addiction. Entertainment-seeking and life service types of smartphone use, and digital literacy were positively associated with smartphone addiction. Conversely, smartphone use for information-seeking and communication-seeking was negatively related to smartphone addiction. CONCLUSION: This study suggests that it is necessary to understand different types of smartphone uses in the elderly and to educate the elderly on digital literacy to prevent smartphone addiction. In future studies, it will be necessary to re-confirm the relationship between smartphone usage type, digital literacy, and smartphone addiction in the elderly (including participants in their 70s or older).

Moderating Effect of Personal and Community Resilience on the Relationship Between Disaster Trauma, Disaster Conflict, Economic Loss, and Post-traumatic Stress Disorder.

OBJECTIVE: This study aimed to investigate the effects of disaster trauma, disaster conflict, and economic loss on posttraumatic stress disorder (PTSD), and to verify the moderating effect of personal and community resilience in these relationships. The data of 1914 people, aged 20 or above, who had experienced natural disasters (earthquake, typhoon, flooding) were used. METHODS: Hayes's (2013) PROCESS macro (Model 1) was conducted to verify the moderation effect of personal and community resilience between PTSD and disaster trauma, disaster conflict, and economic loss. RESULTS: Disaster trauma, disaster conflict, and economic loss were found to be positively related to PTSD. Personal and community resilience were negatively related to PTSD. Resilience had a moderating effect on the relationship between disaster trauma, economic loss, and PTSD. However, there was no moderating effect on the relationship between disaster conflict and PTSD. Community resilience had a moderating effect on the relationship between economic loss and PTSD. However, there was no moderating effect on the relationship between disaster trauma, disaster conflict, and PTSD. CONCLUSIONS: The results suggest that personal and community resilience could be used for prevention and therapeutic interventions for disaster victims who experience PTSD.

The Association Between Depression and Death Anxiety Among Older Adults: Moderating Effect of Ego-Integrity.

This study verifies the relationship between depression and death anxiety in older adults and the moderating effect of ego-integrity on this relationship. The survey was conducted with 236 participants aged 65 years and older through a combination of online and offline surveys. The final data were analyzed using the PROCESS macro for SPSS 2.16. The main findings of this study are as follows: First, depression in old age was positively related to anxiety about death. Second, the moderating effect of ego-integrity was observed on the relationship between depression and death anxiety. Third, on examining the moderating effect of each sub-variable of ego-integrity, the moderating effect of satisfaction with one's life was observed to be significant. Conversely, the moderating effect of attitude toward life and acceptance of old age was not significant. The results of this study are meaningful in examining the moderating effect of ego-integrity on the relationship between depression and death anxiety. Furthermore, the results of this study can provide basic data for the development and application of psychological intervention programs for older adults experiencing psychological problems due to depression and death anxiety in old age.

The Mediating Effect of Digital Literacy on the Relationship between Smartphone Use Motives and Life Satisfaction for Senior Citizens in Korea.

Background: The purpose of this study was to verify the effects of smartphone usage motives on life satisfaction in older adults, and to examine the mediating effect of digital literacy in the relationship between smartphone use motives and life satisfaction. Methods: Data from 2004 participants of the 2018 Smartphone overdependence survey were analyzed by structural equation modeling. Results: Smartphone use for communication had a positive impact on life satisfaction, and smartphone use for leisure negatively influenced life satisfaction. However, smartphone use for information seeking was not directly related to life satisfaction. Communication and information-seeking use motives positively influenced digital literacy, but smartphone use for leisure did not affect. Digital literacy was also positively related to life satisfaction. Finally, communication use motives influenced life satisfaction partially mediating digital literacy, and smartphone use for information seeking influenced life satisfaction, fully mediating digital literacy. Conclusion: By explaining how smartphone use motives significantly affect senior citizens' life satisfaction, this study established the further meaningfulness of digital literacy.

Social Anxiety and Social Networking Service Addiction Proneness in University Students: The Mediating Effects of Experiential Avoidance and Interpersonal Problems.

OBJECTIVE: This study examined the mediating effects of experiential avoidance and interpersonal problems on the relationship between social anxiety and social networking service (SNS) addiction proneness. METHODS: An online survey was conducted on 400 university students in their 20s across Republic of Korea. The scales used in the study were the Social Interaction Anxiety Scale (SIAS), Korean Acceptance-Action Questionnaire-II (K-AAQ-II), Short form of the Korean Inventory of Interpersonal Problems Circumplex Scale (KIIP-SC), and SNS addiction proneness scale for university students. For data analysis, structural equation modeling was conducted, and phantom variables were used to verify the significance of individual indirect effects of the multiple mediation model. RESULTS: Social anxiety had no direct effect on SNS addiction proneness. Experiential avoidance and interpersonal problems completely mediate the relationship between social anxiety and SNS addiction proneness sequentially. CONCLUSION: Our result suggests that experiential avoidance leads to interpersonal problems and SNS addiction proneness. In other words, it is important to alleviate experiential avoidance in treating or preventing interpersonal problems and SNS addiction proneness among university students with social anxiety.

The Analysis of a Causal Relationship between Career Maturity and Academic Achievement on Korean Adolescents Using Autoregressive Cross-Lagged Modeling.

Academic achievement and career maturity are closely related, but an understanding of the causal direction is lacking. The purpose of this study was to analyze the causal relationship between career maturity and academic achievement using autoregressive cross-lagged modeling. This study analyzed the data of 888 adolescents (mean age = 15.90) from the Youth Panel Survey. Autoregressive modeling indicates that academic achievement and career maturity remained stable over time. Higher academic achievement at a previous time point was associated with higher academic achievement at the next time point and similarly for career maturity. Moreover, as a result of cross-lagged effects, academic achievement at one time had a positive effect on career maturity at the next time point, while career maturity at one time had a positive impact on academic achievement at the next time point. In other words, there was a bidirectional effect between academic achievement and career maturity. This study implies that researchers and educators should consider career maturity as well as academic achievement for career guidance.

Depressive Symptoms and Mortality Among Middle-Aged and Older Adults in South Korea.

OBJECTIVE: This study's aim is to verify the longitudinal effect of depressive symptoms on all-cause mortality depending on the age group. METHODS: The Korean Longitudinal Study of Aging's data from 2006 to 2016 were assessed using longitudinal data analysis, and 10,145 participants (age [mean±standard deviation], 61.7±11.1 years; males, 4,426 [43.6%]; females, 5,719 [56.4%]; middle-aged adults, 6,036 [59.5%]; older adults, 4,109 [40.5%]) were included at baseline. The chi-square test, log-rank test, factor analysis, and Cox proportional hazards models were used to investigate the association between depressive symptoms and mortality. To verify that which feelings and behaviors are associated with mortality, factor analysis was used to Center for Epidemiologic Studies Depression (CES-D) scale and it was divided into two factors: negative and positive affects. RESULTS: The hazard ratio (HR) of all-cause mortality for the Q1 (high) of the negative affect factor was higher than the Q3 (low) of this factor (HR, 1.489; 95% confidence interval, 1.284-1.728). Additionally, the association between negative affect and all-cause mortality was stronger in middle-aged adults than older adults. CONCLUSION: The study provided evidence of the longitudinal effect of depressive symptoms on all-cause mortality regardless of age. However, middle-aged adults could be more sensitive to negative feelings and behaviors than older adults.
