Cognitive Behavioral Therapy for Mobile Phone Addiction in Hospitalized Patients

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.

Primary outcomes

  1. Simplified version of the Smartphone Addiction Scale (SAS-SV)

    Time frame: Baseline and Post-intervention (day 5)

    The SAS-SV scale was developed by Min Kwon et al. in 2013, consisting of 10 items, and using a 6-level scoring method.

Secondary outcomes

  1. Self Rating Anxiety Scale (SAS)

    Time frame: Baseline and Post-intervention (day 5)

    The scale consists of 20 items and uses a 4-level scoring system. The higher the total score, the higher the level of anxiety.

  2. Pittsburgh Sleep Quality Index (PSQI)

    Time frame: Baseline and Post-intervention (day 5)

    Used to evaluate the sleep quality over the past month. This scale consists of 19 self-evaluation items and 5 self-evaluation items. Among them, the 19th self-evaluation item and 5 other evaluation items do not participate in scoring. The 18 self-evaluation items participating in the scoring process constitute 7 components, each of which is scored using a 4-point scoring method ranging from 0-3 points. The sum of the scores for each factor is the total PSQI score. A total score greater than 7 indicates the presence of sleep quality issues.

  3. IAT Internet Addiction Questionnaire

    Time frame: Baseline and Post-intervention (day 5)

    The scale consists of 20 items and is rated on a 5-point scale.

  4. General Self Efficacy Scale (GSES)

    Time frame: Baseline and Post-intervention (day 5)

    The scale consists of 10 items and is rated on a 4-point scale.

  5. Self Control Strength Scale (SCS)

    Time frame: Baseline and Post-intervention (day 5)

    The study used the revised Chinese version of the scale. The scale contains 19 items and adopts a 5-point scoring system.

  6. Self Rating Depression Scale (SDS)

    Time frame: Baseline and Post-intervention (day 5)
