Internet addiction in university medical students

AbstractObjectiveTo determine the prevalence of Internet addiction, psychiatric symptoms and personality type in university students, and to correlate these variables.MethodsWe enrolled 522 medical students, 281 men and 241 women, with a mean age of 21.2 years. We used a socio-demographic questionnaire, an Internet questionnaire (Young's Internet Addiction Test [IAT]), the General Health Questionnaire, and the Zuckerman-Kuhlman Personality Questionnaire III (ZKPQ).ResultsThe mean raw score of respondents in the IAT test was 19.72 points. IA had a highly significant correlation with impulsivity (rs=0.244, p<001), neuroticism-anxiety (rs=0.304, p<001) and aggression-hostility (rs=0.143, p=0.001). It also negatively correlated with work effort (rs=−0.136, p=0.002). As for mental health, IA had a highly significant correlation with somatic symptoms (rs=0.174, p<001), anxiety and insomnia (rs=0.219, p<001), social dysfunction (rs=0.118, p<001) and severe depression (rs=0.199, p
