Background: Beyond unambiguous advantages of mobile phones (MP), growing evidences document its problematic use and association with mental health issues. Unintentional injuries, such as road traffic or pedestrian accidents, result from dangerous use of the MP (DUMP). The aim of our study was to estimate the prevalence of DUMP and the addiction to MP in young while driving, cycling or walking (defined as DUMP) relating to some demographic and psychological factors. Methods: A cross-sectional prevalence study was carried out on a sample of 1130 Italian university students. The use and addiction to MP were studied with Italian version of the Mobile Phone Use Questionnaire (MPUQ) and Dependence test of MP (DTMP). The Cognitive Behavioral Assessment 2.0 (CBA 2.0) was used to investigate anxiety and obsessive-compulsive disorder. Results: Result statistics showed a continuous use of MP. One third of subjects showed MP addiction, associated to female and younger students. Two thirds showed risk of DUMP, associated to male and older. The obsessive-compulsive disorder was estimated only in a small fraction and significantly correlated with DTMP. Conclusions: Our study points out the importance that information and prevention campaigns targeting specific demographic subpopulations should be sought to raise young awareness for a safe use of MP.

A variety of behavioural and emotional problems among university students is due to Internet Addiction (Alavi et al. 2012, Rusconi et al. 2012). In 2013 a survey is conducted on a sample of 532 students of University of L’Aquila. The purpose is to investigate Internet use patterns and the correlation between Internet Addiction disorder and compulsive behaviour. Two self-administered questionnaires are used: the Internet Addiction Test and the Cognitive Behavioural Assessment 2.0. 517 students show signs of Internet Addiction, which is moderate for 31% of respondents and severe for 1% of them. 5% shows intrusive thoughts and compulsive behaviours. The symptoms of obsessive-compulsive disorder are statistically associated with Internet Addiction (chi² test=23.53, p=0.000). Among young people there is a relationship between compulsive behaviour and Internet Addiction. This relationship has significant effects on treatment of Internet Addiction.
