Latent categories of adolescents' short video media use tendency and their relationships with personality traits / 中华行为医学与脑科学杂志

Objective:To explore the latent categories of short video media use tendency among adolescents and the influence of personality traits on different categories.Methods:Totally 1 362 adolescents were tested by the five factors of adolescent personality questionnaire and the problematic short video media use scale in March 2022.SPSS 26.0 software was used for data collation and descriptive statistics.Mplus 8.3 software was used for latent profile analysis (LPA) to explore the latent categories of adolescents’ short video media use tendency.Regression mixed model (R3STEP) was used to explore the relationship between different categories of short video media use tendency and personality traits.Results:The short video media use tendency among adolescents was divided into 4 latent categories (by proportion from low to high): " problematic short video media use tendency type" (C4, 11%), " safe short video media use tendency type" (C3, 21%), " social short video media use tendency type" (C1, 29%), and " transitional short video media use tendency type" (C2, 39%). Different personality traits had different effects on the 4 latent categories of short video media use tendency, and using C3 as a reference, openness ( OR=1.95) was a triggering predictor of C1, neuroticism ( OR=0.72) was a protective predictor of C1; cautiousness ( OR=0.46) was a protective predictor of C2, neuroticism ( OR=1.60) was a triggering predictor of C2; cautiousness ( OR=0.33) was a protective predictor of C4, neuroticism ( OR=3.24) was a triggering predictor of C4. Conclusion:There are four different latent categories of Chinese adolescents' short video media use tendency, respectively " safe" , " social" , " transitional" and " problematic" . Further research reveal that, personality traits have a significant impact on the different categories of adolescents' short video media use tendency.This study suggests that educators reasonably guide " transitional" , intervene " problematic" , and focus on helping adolescents with high neuroticism to effectively regulate their negative emotions and reduce the occurrence of problematic short video use.

Social media use in patients with fibromyalgia and its effect on symptom severity and sleep quality

Abstract Background: The aim of this study was to evaluate social media use in patients with fibromyalgia syndrome (FMS) and determine the effect of social media use on disease severity and sleep quality. Materials and methods: In total, 205 social media using patients with similar characteristics were included in the study. The study group consisted of 103 patients with FMS, and the control group consisted of 102 patients without FMS. The FMS symptom severity scale and diffuse pain index were used to determine the disease severity in FMS patients, the sleep disorder short form questionnaire (PROMIS) was used to evaluate sleep quality, and the Social Media Addiction Scale-Adult Form was used to evaluate social media addiction. A visual analog scale was applied to evaluate pain in both the patient and control groups, and social media usage times were recorded. Results: We found that pain severity, sleep disturbance and social media addiction were higher in patients with FMS than in the control group, and there was no relationship between the rates of social media use in patients with FMS and the severity and prevalence of the disease. Conclusion: The use of social media is more frequent in patients with FMS, which can motivate healthcare professionals to evaluate social media habits in individuals with FMS.

Trends in Digital Media Use in Korean Preschool Children

BACKGROUND: Children today are exposed to various media devices, and their usage of these is increasing. Prior studies have outlined forms of harm this can potentially cause. However, there has been little empirical research on the use of media devices among preschool children in Asia. The aim of this study was to examine and analyze longitudinal trends in media device use among Korean preschool children, focusing on the frequency of engagement, time spent with, and ownership of media devices, delineated by sex. METHODS: Four hundred parents of children aged 2–5 years were invited to enroll. The baseline assessment, Wave 1, was conducted between December 2015 and June 2016, and follow-up assessments, Wave 2 and Wave 3, were conducted annually for the following 2 years. Time of media use, frequency of media use, and ownership of media devices (TV, tablet PCs, and smartphones) were investigated. RESULTS: Ownership of tablet PCs increased significantly between Wave 1 and Wave 3 for boys and girls (corrected P < 0.001). Frequency of media use increased significantly between Wave 1 and Wave 3 only in boys' use of tablet PCs (mean difference 0.8 day/wk). Time of media use increased significantly between Wave 1 and Wave 3 for both sexes in all devices, measured by mean difference on weekdays and weekends (TV by 0.6 and 0.7 hr/day, tablet PCs by 0.6 and 0.8 hr/day, and smartphones by 0.4 and 0.4 hr/day). Children spent more time using media devices during weekends than on weekdays. CONCLUSION: This study observed an increase in the tendency of media device use among preschool children in Korea. The patterns of use indicate that paying attention to the types of devices children use is needed, as well as vigilance on weekends.

Political Interest, Political Efficacy, and Media Usage as Factors Influencing Political Participation in Hospital Nurses / 간호행정학회지

PURPOSE: The purpose of this study was to identify how political interest, efficacy and media usage influence political participation in hospital nurses. METHODS: Participants were 286 nurses, who were informed of the study purpose and agreed to participate. Data were collected during November and December, 2012 using a questionnaire on political interest, political efficacy, media usage and political participation. Data were analyzed using t-test, ANOVA, Scheffe's test, Pearson Correlation Coefficients, and Multiple Stepwise Regression. RESULTS: Scores for political participation and political interest was average. The score for political efficacy was higher than average. Political participation was significantly different by education level, job career, position, and intention to vote in the election for the 18th President. Political participation had a moderate positive correlation with political interest (r=.50, p<.001), political efficacy (r=.32, p<.001) and media usage (r=.14, p=.022). Political interest (beta=.43) was the factor most influential on political participation, explaining 25% of the variance. A total of 32% of political participation was explained by political interest, political efficacy, and TV news or SNS for media use. CONCLUSION: The results suggest that it is necessary to develop strategies to promote political interest and political efficacy for hospital nurses to improve political participation.
