This study aimed to examine the effective parental impact in preventing problematic smartphone use in adolescents by identifying the parent-related factors. A secondary analysis of cross-sectional data from a Korean national survey was conducted. Data from 2758 male and 2419 female adolescents, aged 10 to 19 years, were analyzed; the respondents were divided into normal and risk groups based on their standardized smartphone addiction diagnostic scale scores. Parent-related factors of smartphone addiction were analyzed using a logistic regression model. Among both male and female adolescents, mobile messenger usage, and family environment emerged as significant predictors of problematic smartphone use. In addition, for male adolescents, smartphone use frequency and parent’s awareness of content use were significant predictors. The findings indicated the importance of parental roles in preventing problematic smartphone use in adolescents. Parents should create a healthy family environment by avoiding smartphone overuse and modeling the appropriate usage of smartphones.

Diabetes self-care is explained as an illness-related coping behavior. Health literacy is an important predictor in self-care behaviors. However, little is known about their association with illness perception in Korean immigrants with diabetes. This study aimed to examine the relationships among health literacy, illness perception, and diabetes self-care in Korean-speaking immigrants with diabetes. This cross-sectional study was conducted in 2020. A convenience sample of 52 Korean adults with diabetes in Dallas-Fort Worth areas completed a survey. Data were analyzed using SPSS (version 25) with statistical significance at α < .05. The mean of health literacy was high (11.1, SD = 1.1, ranges 0–12). There were no statistically significant associations between health literacy, illness perception, and diabetes self-care. Language barriers are considered a literacy issue, but health literacy and limited English proficiency must be approached differently by health care providers.
