High　rates　and　serious　negative　consequences　of　pathological　Internet　use　(PIU)　have　been　reported　among　young　adults;　thus,　we　aimed　to　identify　the　impacts　of　demographic,　socioenvironmental,　and　psychological　factors　on　PIU　in　this　population.　We　conducted　a　cross-sectional　study　with　501　Chinese　university　students,　who　completed　Young＇s　Internet　Addiction　Test,　the　Egna　Minnen　Betraffande　Uppfostran,　the　Eysenck　Personality　Questionnaire,　and　the　Coping　Style　Questionnaire.　Results　showed　that　age,　gender,　father＇s　refusal　or　denying,　and　father＇s　overprotectiveness　had　positive　impacts　on　PIU,　whereas　the　rural/urban　nature　of　the　area　in　which　participants　grew　up　and　mother＇s　emotional　warmth　and　understanding　had　negative　impacts　on　PIU.　Further,　greater　psychoticism　and　use　of　the　avoidant　coping　style　were　related　to　higher　PIU,　whereas　greater　use　of　the　self-blaming　coping　style　was　associated　with　lower　PIU.　These　factors　should　be　considered　when　developing　interventions　aimed　at　decreasing　PIU.
