摘要：As adolescents using mobile phone rapidly increase, the associated problems are also reported, one of which is mobile phone dependency. While several cross-sectional studies revealed the associations between mobile phone use and mobile phone dependency, little is known about the causal directions between the two variables. To examine the causality, this study developed and empirically tested a series of autoregressive cross-lagged models where prior mobile phone dependency predicts both subsequent mobile phone dependency and mobile phone use, and vice versa, using longitudinal data. The data of 1,148 adolescent mobile phone users from Korean Children and Youth Panel Survey of Grade 4 students who were followed for 6 years (2010-2015) were analyzed using structural equation modeling. Results suggested that prior mobile phone dependency predicted subsequent mobile phone use, while prior mobile phone use didn�t predict subsequent mobile phone dependency. Empirical evidence was found for mobile phone dependency as a causal precedence to mobile phone use.
