The incidence of Internet addiction was stable among teenagers during the three years ( F = 2.53, P = 0.08); The multivariate linear regression analysis showed that positive youth development, good family functioning indicators and academic maladaptation could predict the higher probability of having Internet addiction ( P <0.05).
