RESUMEN
This study examined the relationships between marketing exposure, in-game purchase, problem gaming, online simulated gambling game playing, and psychological distress. Data were obtained from a sample of 2,595 seventh-grade students from 30 middle schools in Taiwan. A self-administered questionnaire was conducted in 2020. The results indicated that 94% of adolescents engage in online gaming, with 38% making in-game purchases, and 9% playing online simulated gambling games. The multiple regression results showed that adolescents who are exposed to higher levels of gaming marketing, influenced by advertising effects, involved in in-game purchases, and have lower levels of active parental mediation were more likely to experience problem gaming. Adolescents who have increased exposure to gambling game marketing, are influenced by advertising effects, are involved in in-game purchases, and who are experiencing problem gaming were more likely to engage in online simulated gambling game playing and token purchasing. Involvement in in-game purchases, problem gaming, and playing online simulated gambling games were associated with higher levels of psychological distress and poor sleep quality. In conclusion, the results of this study link adolescents' exposure to marketing with their involvement in in-game purchases, problem gaming, and engaging in online simulated gambling.
RESUMEN
BACKGROUND: In this study we examined the phenomena of smartphone addiction, online harassment, and school bullying/victimization to predict the prospective influence these could have on the onset and persistence of sleep problems and depression among children. METHODS: Responses from 2155 fifth-grade children recruited from 30 primary schools in Taipei were assessed, and a follow-up was performed in the 6th grade. Self-administered questionnaires were collected for each year. FINDINGS: Children who reported smartphone addictions, online harassment, and school bullying/victimization coupled with an increase in those factors were more likely to experience the onset and persistence of sleep problems. In addition, children who reported smartphone addiction, online harassment, school bullying/victimization, and poor sleep quality were more likely to experience the onset and persistence of depression. IMPLICATIONS: School nurses or pediatric nurses should be able to assess children's Internet use and risks to understand potential influences on sleep quality and mental status and provide recommendations for children, parents and schools.

OBJECTIVE: This study examined the relationships between parental mediation and Internet addiction, and the connections to cyberbullying, substance use, and depression among adolescents. METHOD: The study involved 1808 junior high school students who completed a questionnaire in Taiwan in 2013. RESULTS: Multiple logistic regression analysis results showed that adolescents who perceived lower levels of parental attachment were more likely to experience Internet addiction, cyberbullying, smoking, and depression, while adolescents who reported higher levels of parental restrictive mediation were less likely to experience Internet addiction or to engage in cyberbullying. Adolescent Internet addiction was associated with cyberbullying victimization/perpetration, smoking, consumption of alcohol, and depression. CONCLUSION: Internet addiction by adolescents was associated with cyberbullying, substance use and depression, while parental restrictive mediation was associated with reductions in adolescent Internet addiction and cyberbullying.

RESUMEN
In this study, we examined the relationships between the use of online dating applications (apps), online victimization, and psychosocial distress among adolescents. This study was conducted in 2020. A sample of 2595 seventh-grade students from 30 Taiwanese middle schools was surveyed. We conducted a self-administered survey. Overall, 15% of the adolescents reported using online dating apps in the past year, while 78% reported having seen dating app advertisements on the internet in the past year. Multivariate analysis results indicated that adolescents' exposure to the marketing of dating apps and poor academic performance were both associated with the use of online dating apps. Adolescents who used dating apps were more likely to experience online privacy victimization, cyberbullying victimization, and online sexual harassment. The use of dating apps by adolescents, online privacy victimization, cyberbullying victimization, and online sexual harassment were associated with higher levels of depression, anxiety, and stress. In conclusion, adolescent use of dating apps is related to online victimization and psychological distress.
RESUMEN
In this study, we examined influencer marketing and consumption of non-alcoholic beer by adolescents to determine how these factors could affect the intentions of adolescents to purchase and drink alcohol. A total of 3121 high-school students recruited from 36 schools in Taiwan completed a self-administered questionnaire during the COVID-19 pandemic in 2022. The results indicate that 19% of these adolescents consumed non-alcoholic beer and 28% consumed alcohol in the past year. Multivariate analysis positively associated adolescents' exposure to influencer marketing with their purchase and consumption of non-alcoholic beer. Adolescents' exposure to influencer marketing of non-alcoholic beer combined with lower levels of parental restrictive mediation was associated with increased odds of the purchase and consumption of alcohol. For individuals who did not purchase alcohol in the past year, both the exposure to influencer marketing and the consumption of non-alcoholic beer were associated with intending to purchase alcohol in the future. Similarly, individuals who previously abstained from the consumption of alcohol, both the exposure to influencer marketing and the consumption of non-alcoholic beer were associated with intending to consume alcohol. In conclusion, when adolescents were exposed to influencer marketing of non-alcoholic beer they were more likely to consume it, which resulted in an increased likelihood that they would then purchase and consume alcohol.
RESUMEN
This study examined the relationships between children's mobile gaming preferences, online risks, and mental health. Data were obtained from a sample of 2,702 third and fourth grade students from 16 elementary schools in Taiwan and 9 schools in China. A self-administered questionnaire was used. The mental state of the children who participated in the study was assessed using the Strengths and Difficulties Questionnaire (SDQ), while mobile gaming addiction was assessed using the short form of the Internet Gaming Disorders Scale (IGDS9-SF). The results showed that about 54% of children played mobile games with others (multi-player), while 31% played mobile games alone, and 15% did not play mobile games. Multiple logistic regression results indicated that behaviors such as participating in multi-player games, playing violent games, a poor parent-child relationship, and living in a rural area were associated with a greater risk of mobile gaming addiction. Involvement in multi-player games, playing violent games, mobile gaming addiction, and exposure to mobile violence/pornography were associated with greater risks of cyber aggression/victimization. Multiple regression results showed that being a multi-player, playing violent games, mobile gaming addiction, exposure to violence/pornography, exposure to cyber aggression/victimization, and having a poor parent-child relationship were associated with emotional and behavioral problems.

In this study, we examined excessive online gaming by adolescents and the resultant effects of their exposure to the online marketing of energy drinks and alcohol, and whether marketing literacy could serve as a mitigating factor. This cross-sectional study was conducted in 2020. Data were obtained from a sample of 2613 seventh-grade students from 30 middle schools in Taiwan. A self-administered questionnaire was conducted. The results showed that nearly 18% of the adolescent respondents had used energy drinks, while 75% reported seeing energy-drink advertisements on the internet in the past year. Multiple regression results indicated that factors such as being male, reporting excessive gaming, being exposed to higher levels of online energy-drink marketing, and reporting alcohol use were positively associated with energy-drink consumption. A higher level of online energy-drink marketing-affective literacy, however, was negatively associated with energy-drink consumption. In conclusion, factors that predicted energy-drink consumption among adolescents included excessive gaming and exposure to online energy-drink marketing, but marketing-affective literacy tended to lessen the impact of such advertising.

This study assessed the discrepancies between reports from parents and children concerning children's exposure to violence/pornography on mobile devices and the impact on the psychosocial adjustment of children. Data were obtained from a sample of 2,230 parent-child dyads recruited from 16 elementary schools (1,140 dyads) in Taiwan and 9 schools (1,090 dyads) in China. A self-administered questionnaire was used. The results showed that about 30 percent of children reported being exposed to violence on mobile devices. Approximately 70 percent of their parents were unaware of their child's exposure to violence on mobile devices. About 16 percent of children reported exposure to pornography on mobile devices, and 80 percent of their parents were unaware of this exposure. Multinomial logistic regression results showed that after controlling for parent and child sociodemographic variables, factors related to parental unawareness of child exposure to violence on mobile devices included a child's ownership of mobile devices, smartphone/tablet use time, a lower level of parental understanding, and a residence in China or in a rural area, whereas the parent-child relationship and a child's smartphone/tablet use time were associated with parents who were unaware of their child's exposure to pornography. Multiple regression results showed that children who were living with household poverty, had a poor parent-child relationship, spent much time using a smartphone/tablet, and with parents who were unaware of their exposure to violence/pornography on mobile devices were more likely to have emotional and behavioral problems.

This study assessed the computer/mobile device screen time and eye care behavior of children and examined the roles of risk perception and parental practices. Data were obtained from a sample of 2,454 child-parent dyads recruited from 30 primary schools in Taipei city and New Taipei city, Taiwan, in 2016. Self-administered questionnaires were collected from students and parents. Fifth-grade students spend more time on new media (computer/smartphone/tablet: 16 hours a week) than on traditional media (television: 10 hours a week). The average daily screen time (3.5 hours) for these children exceeded the American Academy of Pediatrics recommendations (≤2 hours). Multivariate analysis results showed that after controlling for demographic factors, the parents with higher levels of risk perception and parental efficacy were more likely to mediate their child's eye care behavior. Children who reported lower academic performance, who were from non-intact families, reported lower levels of risk perception of mobile device use, had parents who spent more time using computers and mobile devices, and had lower levels of parental mediation were more likely to spend more time using computers and mobile devices; whereas children who reported higher academic performance, higher levels of risk perception, and higher levels of parental mediation were more likely to engage in higher levels of eye care behavior. Risk perception by children and parental practices are associated with the amount of screen time that children regularly engage in and their level of eye care behavior.

OBJECTIVES: The present study examined factors associated with the emergence and cessation of youth cyberbullying and victimization in Taiwan. METHODS: A total of 2,315 students from 26 high schools were assessed in the 10th grade, with follow-up performed in the 11th grade. Self-administered questionnaires were collected in 2010 and 2011. Multiple logistic regression was conducted to examine the factors. RESULTS: Multivariate analysis results indicated that higher levels of risk factors (online game use, exposure to violence in media, internet risk behaviors, cyber/school bullying experiences) in the 10th grade coupled with an increase in risk factors from grades 10 to 11 could be used to predict the emergence of cyberbullying perpetration/victimization. In contrast, lower levels of risk factors in the 10th grade and higher levels of protective factors coupled with a decrease in risk factors predicted the cessation of cyberbullying perpetration/victimization. CONCLUSION: Online game use, exposure to violence in media, Internet risk behaviors, and cyber/school bullying experiences can be used to predict the emergence and cessation of youth cyberbullying perpetration and victimization.

This study examined the relationship between parental and adolescent eHealth literacy and its impact on online health information seeking. Data were obtained from 1,869 junior high school students and 1,365 parents in Taiwan in 2013. Multivariate analysis results showed that higher levels of parental Internet skill and eHealth literacy were associated with an increase in parental online health information seeking. Parental eHealth literacy, parental active use Internet mediation, adolescent Internet literacy, and health information literacy were all related to adolescent eHealth literacy. Similarly, adolescent Internet/health information literacy, eHealth literacy, and parental active use Internet mediation, and parental online health information seeking were associated with an increase in adolescent online health information seeking. The incorporation of eHealth literacy courses into parenting programs and school education curricula is crucial to promote the eHealth literacy of parents and adolescents.

PURPOSE: The present study examined the psychosocial factors associated with the initiation and persistence of Internet addiction among adolescents in Taiwan. METHODS: A total of 2315 students from 26 high schools were assessed in the 10th grade, with follow-up performed in the 11th grade, in Taipei, Taiwan. Self-administered questionnaires were collected in each year to assess the pattern of changes in Internet addiction and psychosocial factors. RESULTS: Of the 1602 students without an Internet addiction in the 10th grade, 253 (15.8%) had initiated Internet addiction by grade 11. Multivariate analysis results indicated that greater engagement in online activities (i.e., social network website use, online gaming), depression, and lower school bonding in grade 10 coupled with an increase in online activities, depression, and smoking from grades 10 to 11 predicted the initiation of Internet addiction. Of the 605 students with Internet addiction in the 10th grade, the addiction had persisted for 383 students (63.3%) in grade 11. An increase in the existence of depression and alcohol use from grades 10 to 11 predicted the persistence of Internet addiction. CONCLUSIONS: Online activities, depression, and substance use were important predictors of youth initiation and of the persistence of Internet addiction.

BACKGROUND: Youth consumption of alcohol is a major public health problem in Taiwan, yet little research has been conducted to examine the potential influence of exposure to alcohol advertising. The present study examined the prospective influence that exposure to alcohol advertising has on the initiation and persistence of youthful drinking in Taiwan. METHODS: A total of 2315 students from 26 high schools in Taipei, Taiwan were assessed in the 10th grade with follow-up conducted in the 11th grade. Self-administered questionnaires were collected in 2010 and 2011 to assess the patterns of change in youth alcohol drinking behaviors, media exposure to alcohol, and risk and protective factors. RESULTS: Of the 1712 non-drinking students in the 10th grade, 285 (16.6%) had initiated drinking by the 11th grade. Of the 590 drinkers in the 10th grade, 396 (67.1%) were persistently drinking by the 11th grade. Multivariate analysis results indicated that when other potential confounders were accounted for, greater media exposure to alcohol advertising in the 10th grade was found to be significantly associated with the initiation of alcohol use and when combined with an increase in media exposure from grades 10 to 11, this was significantly associated with the persistence of alcohol use. CONCLUSION: Exposure to alcohol advertising in the media was associated with both the initiation and the persistence of alcohol use by youth.

BACKGROUND: This study examined the relationships among cyberbullying, school bullying, and mental health in adolescents. METHODS: In 2010, a total of 2992 10th grade students recruited from 26 high schools in Taipei, Taiwan completed questionnaires. RESULTS: More than one third of students had either engaged in cyberbullying or had been the target (cybervictim) of it in the last year. About 18.4% had been cyberbullied (cybervictim); 5.8% had cyberbullied others (cyberbully); 11.2% had both cyberbullied others and been cyberbullied (cyberbully-victim). About 8.2% had been bullied in school (victim); 10.6% had bullied others (bully); and, 5.1% had both bullied others and had been bullied in school (bully-victim). Students with Internet risk behaviors were more likely to be involved in cyberbullying and/or cybervictimization; students who had cyberbullying or victimization experiences also tended to be involved in school bullying/victimization. After controlling for sex, academic performance, and household poverty, cyber/school victims and bully-victims were more likely to have lower self-esteem, and cyber/school victims, bullies and bully-victims were at a greater risk for serious depression. CONCLUSIONS: Both cyberbullying and school bullying and/or victimization experiences were independently associated with increased depression.

OBJECTIVE: The present study examined the relationships between thin-ideal media exposure, body dissatisfaction, and disordered eating behaviors among adolescents in Taiwan. METHOD: A total of 2992 students in the 10th grade were recruited from 26 high schools in Taipei, Taiwan to complete a questionnaire in 2010. RESULTS: The results showed that the adolescents were exposed to thin-ideal messages a few times a week. Females had higher levels of thin-ideal media exposure, media pressure to be thin, thin-ideal internalization, body dissatisfaction, and disordered eating behaviors than males. Multivariate logistic regression results indicated that media pressure and thin-deal internalization significantly increased the likelihood of body dissatisfaction, while media pressure and body dissatisfaction contributed to both restrained eating and unhealthy weight control behaviors, when all other variables were controlled for.

A simple, sensitive and specific high-performance liquid chromatographic method has been developed for the first time to simultaneously determine the eight major biologically active ingredients, namely paeoniflorin, naringin, sennoside A, baicalin, baicalein, saikosaponin a, rhein and emodin of the Chinese herbal formula Da-Chai-Hu-Tang. The contents of these marker substances in Da-Chai-Hu-Tang extract could be easily determined within 85 min. The assay was reproducible and accurate with overall intra-day variations and accuracy of less than 2% and more than 97.9%, respectively. Results indicate that the developed HPLC assay can be successfully utilized as a quality control method for simultaneous determination of eight representative substances in Da-Chai-Hu-Tang.
