Internet addiction and mobile phone addiction are both forms of technology addiction, and thus would be expected to show similarities and differences. This study investigated the association between the Internet Addiction Test (IAT) and the Mobile Phone Dependence Questionnaire (MPDQ) as a test of concurrent validity. Participants were 1,072 students aged between 9 and 18 years old (63% male and 37% female) from three primary schools and three secondary schools in Hong Kong. Correlations showed that scores on the two measures were moderately correlated, providing further evidence of each measure’s validity. Confirmatory factor analysis that the IAT’s factor structure was similar in both younger and older samples, suggesting that it is developmentally appropriate for primary and secondary school students. Latent Class Analysis showed that 4 classes or 5 classes are appropriate for IAT's score classification. ROC analyses showed similar rates of participants with high scores on the IAT and on the MPDQ. The outcomes have implications for the prevention and treatment of Internet and mobile phone addiction. Future research can establish norms for different ages, genders and cultural groups.

Objective: This article aims to explore the development of scholarly articles relating to couple therapy in Greater China in academic journals in the past four decades between 1976 and 2016. Method: This review analyzes 278 couple therapy articles with a focus on the question of “who are the authors?” and “what kinds of articles published?” Results: The volume of Taiwan, Mainland China, Hong Kong, and Macau articles are 90, 88, 64, and 0, respectively; 190 of them are group authorship, and the first research was published in 1984. Women are 3 times more likely than men to be the key target group, and almost two third of the works are identified as academic-led research. Conclusions: Indigenization of couple therapy research in Greater China with reference to its social and political context is addressed. The motto is, “think global but act local and promote the local to inform the global.”

This study tested perceived meaning in life (an individual variable), and adolescent-parent attachment (a systemic variable), as well as other Internetrelated emotions and behaviors, as predictors of Problematic Internet use. A random selection of 479 students from six secondary schools in Hong Kong, aged between 11 and 19 years old (40.3% male and 59.7% female) completed questionnaires (C-IAT, C-MLQ, C-IPPA, DASS21) in their classrooms. Path analysis showed that only adolescent-father attachment was the strongest predictor of Problematic Internet use, with presence of meaning, time using the Internet on weekends, education level, depression and stress level also contributing significant variance. The results have implications for future research and the prevention and treatment of Problematic Internet use. Our study used a multivariate approach to test whether adolescent-parent attachment and meaning in life could predict adolescent PIU. This study is a major step towards understanding the individual and systemic variables that may play a role in the development of PIU.
