 The study investigates the association between psychosocial aspects of mobile phone use and mental health symptoms in a prospective cohort of young adults. The results show that high frequency of mobile phone use at baseline was a risk factor for mental health outcomes at one year follow-up among the young adults. The risk for reporting mental health symptoms at follow-up was greatest among those who had perceived accessibility via mobile phones to be stressful. Public health prevention strategies focusing on attitudes could include information and advice, helping young adults to set limits for their own and others' accessibility.
