Our research concerns the problematic use of a mobile phone, which was carried out on a Polish sample. We adapted an instrument to measure that construct, created by Bianchi and Phillips – Mobile Phone Problematic Use Scale (MPPUS). The Polish equivalent of this scale, developed by Izdebski and Kotyśko, is called the Problematic Cell Phone Use Questionnaire (PCPUQ). Our main goal was to determine if personality variables and depression are related to using a mobile phone. The study included 315 mobile phone users between the ages 18 to 62. Results showed that problematic mobile phone use was related to a young age, extraversion, low agreeableness and a high level of depression.
