Our study is a novel and creative contribution to the interaction of modern technology with common psychopathology. At the same time, it adds to our knowledge of the clinical phenomenology of PD. The mobile phone may be working as a "phobic partner" for some patients; however, their behavior and specific characteristic make the MP unique, and consequently, the use of the MP deserves a psychopathological description. The questions of our study are not absolutely specific to the relationship between the use of the MP and PD. Some questions may also be related to other mood or anxiety disorders. Further trials and improvements to our questionnaire may promote the quality of future psychopathological studies.
