中文摘要：

采用广义问题性网络使用量表、幸福感指数量表、社交焦虑量表、流调中心抑郁自评量表对465名大学生进行了间隔6个月的两次调查．以探索问题性网络使用与幸福感、社交焦虑、抑郁之间的关系。结果表明：（1）问题性网络使用与幸福感显著负相关，与社交焦虑、抑郁显著正相关；（2）问题性网络使用与幸福感、社交焦虑、抑郁之间存在单向预测作用．即前期的问题性网络使用能够显著预测后期的幸福感、社交焦虑、抑郁。并且这种预测作用存在性别差异。对于男生．前期的问题性网络使用能够显著预测后期的社交焦虑；对于女生，前期的问题性网络使用能够显著预测后期的幸福感和抑郁。

英文摘要：

To explore the relationship between problematic internet use, well-being, social anxiety and depression, 465 undergraduates were measured with Generalized Problematic Internet Use Scale, Index of Well-being Scale, Social Anxiety Subscale and Center for Epidemiologic Studies Depression Scale twice within the 6 months interval. The results indicated： 1） Problematic internet use was negatively related to well-being, positively related to social anxiety and depression. 2） Problematic internet use had a cross-time prediction on well-being, social anxiety and depression, which showed obvious gender differences. For boys, early problematic internet use could predict later social anxiety; for girls, early problematic internet use could predict later well-being and depression.
