  • A mobile phone usage survey was administered to a nationwide sample of 3,617 adolescents. Major motivations of mobile phone usage were mobility/real-time connection, show off, information acquisition, entertainment, dialogue, schedule management, and advice. Maintenance of social relationship with the peer group was most important in mobile phone use. Motivations influenced mobile phone dependency : show off had the strongest influence on anxiety/paranoia followed by dialogue, entertainment, mobility/real-time connection. Without their phones, fashion-oriented adolescents showed mobile phone dependency and anxiety. Stronger dialogue and entertainment motivations were associated with weaker real time connection motivation and stronger paranoia symptoms. Mobile phone dependent adolescents had lower grades, showed lack of attention, had little dialogue with their parents and showed withdrawal from the peer group.

  • Mobile phone users have diversified human factors: their channel orientations are different, and the degrees of unwillingness to communicate vary. We examined the effect of human factors on the use of mobile phone, such as the diversity of mobile phone use, the appropriateness of mobile phone, and the aversion to mobile phone as well as the interpersonal communication network through mobile phone. For our sample we surveyed college students and their family members who are older than 400. We found that the more social presence a mobile phone user gets through the mobile phone, and the more familiar to the mobile phone he/she is, (1) the more diversified is the use of mobile phone service, (2) the higher is the level of acceptance of the mobile phone as an interpersonal communication media, and (3) the lower is the level of aversion to the mobile phone. In contrast, those who have some level of aversion to the face-to-face communication, seem to form very limited interpersonal communication network through mobile phone. Their use of mobile phone is also very limited.

  • This study aimed to demonstrate the complex and structural relationships between (a) the purposes of using mobile phones, and (b) the levels of mobile phone dependency and depressive symptoms among elementary school students. We analyzed data from the 3rd Korean Children and Youth Panel Survey using structural modeling. Results showed the level of mobile phone usage for contacting family members negatively affected the mobile phone dependency. However, the levels of mobile phone usage for contacting friends and personal entertainment positively influenced the mobile phone dependency. Mobile phone dependency positively affected depressive symptoms. Mobile phone dependency partially mediated the relationship between the level of mobile phone usage for contacting family members and depressive symptoms. Mobile phone dependency fully mediated two relationships: (1) between the level of mobile phone usage for contacting friends and depressive symptoms and (2) between the level of mobile phone usage for personal entertainment and depressive symptoms.

  • As mobile phone has acquired a status of a fashion item expressing one's character, it is necessary to understand the fashion needs for this new fashion product. The purpose of this study was to apply the fashion orientation construct developed in the clothing research field to mobile phone and explore its validity. The multi-dimensional construct of fashion orientation which most widely represented the fashion aspects was examined for the two product categories of clothing and mobile phone. Data were collected from an online questionnaire survey, and a total of 1,136 responses were analyzed. The construct structure of fashion orientation of mobile phone resulted in individuality, innovation, and fashion was different from that of clothing extracted to interest/importance, fashion/innovation, and individuality. Fashion sensitivity and an early adoption of a new product were two different dimensions in mobile phone while not separable in clothing. Despite a higher predictability of the fashion/innovation orientation of clothing on fashion orientation rather than on innovation orientation of mobile phone, innovation orientation was more important to purchase behaviors of mobile phone. The study still implies that it is valid to use clothing fashion innovative consumers for mobile phone marketing.

  • The purpose of this study was to examine the effects of parental abuse and neglect, as well as that of children's peer attachment, on mobile phone dependency. Data were obtained from the Korean Child-Youth Panel Survey (KCYPS), and the participants were 1,892 (909 boys, 983 girls) elementary students (5th graders) who had a mobile phone. To measure the variables, this study used such scales as the parental abuse and neglect scale, peer attachment scale, and mobile phone dependency scale. The data were analyzed using descriptive statistics, Pearson's correlation, and structural equation modeling analysis. The results of the study were as follows: First, parental abuse and neglect had direct negative effects on children's peer attachment; that is, the more parental abuse and neglect, the less children's peer attachment. Second, parental abuse and neglect had direct positive effects on mobile phone dependency; that is, the more parental abuse and neglect, the greater children's mobile phone dependency. However, children's peer attachment did not directly affect mobile phone dependency; that is, children's peer attachment did not have a mediating effect between parental abuse and neglect, and mobile phone dependency. In conclusion, parental abuse and neglect influence children's peer attachment and mobile phone dependency. Thus this study showed that parental abuse and neglect, rather than children's peer attachment, affect children's mobile phone dependency.

  • Objective: The possibility that smoking prevalence among junior and senior high school students may decrease with increasing mobile phone bill was reported by the mass media in Japan. We conducted a nationwide survey on adolescent smoking and mobile phone use in Japan in order to assess the hypothesis that mobile phone use has replaced smoking. Methods: A total of 70 junior high schools (response rate; 71%), and 69 high schools (90%) from all over Japan responded to 2005 survey. Students in the responding schools were asked to fill out an anonymous questionnaire about smoking behavior, mobile phone bill, and pocket money. Questionnaires were collected from 32,615 junior high school students and 48,707 senior high school students. Results: The smoking prevalence of students with high mobile phone bill was more likely to be high, and that of students who used mobile phones costing 10,000 yen and over per month was especially high. When "quitters" were defined as students who had tried smoking but were not smoking at the time of survey, the proportion of quitters decreased as the mobile phone bill increased. The proportion of students who had smoking friends increased with the increase in the mobile phone bill per month. Conclusion: The hypothesis that the decrease in smoking prevalence among Japanese adolescents that has been observed in recent years is due to a mobile phone use can be rejected.
