Young People Aged 18-25 With Depression or Anxiety Mood Participate in an LLM-based Digital Dialogue Intervention Study

"Douyin Xinqing is an AI dialog bot. Users can start chatting with the Douyin companion bot by clicking on the Direct Message on the homepage of their accounts on Douyin app.~After a user sends any message to the Douyin companion bot, it first asks the user about his or her mood and guides him or her to start chatting around his or her emotions. According to the situation described by the user, the companion bot expresses empathy, asks questions to guide the user to talk, and provides suggestions at the appropriate time. Users can also record their emotions every day and look back regularly to observe changes in their inner feelings. In addition, the Douyin companion bot can also identify crisis situations such as suicide and severe mental illness and, if necessary, guide users to call the hotline to obtain professional psychological assistance."

Only the users in the waiting group had the task of waiting for the first four weeks, and they completed the three questionnaires at exactly the same point in time as those in the intervention group. Only after the first four weeks of intervention did the waiting group begin to receive the 28-day conversational intervention, and no additional questionnaires were interspersed in between.
