BACKGROUNDS: Internet addiction (IA) has become a major public health issue worldwide and is closely linked to @entity146 and suicide. The present study aimed to investigate the prevalence of IA and its associated psychosocial and psychopathological determinants among internet users across different age groups. METHODS: The study was a cross-sectional survey initiated by the Taiwan Suicide Prevention Center. The @entity1 were recruited from the general public who responded to the online questionnaire. They completed a series of self-reported measures, including Chen Internet @entity988 Scale-revised (CIAS-R), Five-item Brief Symptom Rating Scale (BSRS-5), Maudsley Personality Inventory (MPI), and questions about suicide and internet use habits. RESULTS: We enrolled 1100 respondents with a preponderance of female subjects (85.8%). Based on an optimal cutoff for CIAS-R (67/68), the prevalence rate of IA was 10.6%. @entity1 with higher scores of CIAS-R were characterized as: male, single, students, high @entity663 , @entity73 due to internet use, time for internet use, online gaming, presence of @entity146 morbidity, recent suicide ideation and past suicide attempts. Multiple regression on IA showed that age, gender, @entity663 , @entity73 , internet use time, and BSRS-5 score accounted for 31% of variance for CIAS-R score. Further, logistic regression showed that @entity663 , @entity73 and internet use time were three main predictors for IA. Compared to those without IA, the internet addicts had higher rates of @entity146 morbidity (65.0%), suicide ideation in a week (47.0%), lifetime suicide attempts (23.1%), and suicide attempt in a year (5.1%). CONCLUSION: @entity1314 traits, psychopathology, time for internet use and its subsequent @entity73 were important predictors for IA. Individuals with IA may have higher rates of @entity146 morbidity and suicide risks. The findings provide important information for further investigation and prevention of IA.
