Brief Summary

Problematic mobile phone use is excessive dependence and use of electronic products and their functions, which affects the daily life of users. Previous studies have shown that mobile phone addiction is related to depression, anxiety severity, and stress, and it is negatively correlated with sleep quality. For hospitalized patients in the mental health department, symptoms such as anxiety, depression, and poor sleep are very common. Cognitive behavioral therapy has been widely applied in online gaming addiction and is also effective in intervening in mobile phone addiction. Therefore, Hospitalized patients in the mental health department will be randomized to either the CBT interventions or an control group. The main outcome measure is the Simplified Smartphone Addiction Scale (SAS-SV), measured before intervention and after the completion of the last brief intervention.
