Numerous studies have indicated that people who use a mobile phone while driving have a greater chance of being involved in accidents than those who do not. There have also been many studies investigating the effectiveness of various interventions aimed at reducing the problem, but none of these has been from a social work perspective. This study, however, is based on this viewpoint, and investigated the effectiveness of Cognitive Behavioral Therapy in alleviating the problems caused by the use of mobile phones while driving. The study was developed using a quantitative research design, with a sample consisting of 38 university students who use their mobiles while driving. The students were chosen according to specific criteria, and thus formed a purposive sample. The study compared an experimental group who went through an intervention program with a control group. The results showed significance differences between the two groups in the degree of the use of mobile phones while driving; a specific scale measured the use by the two groups both before and after the intervention, as well as at a later follow-up stage. This indicated that CBT was successful in reducing the use of mobile phones while driving.
