Brief Summary

Patients with PSD have the characteristics of high incidence rate, difficult identification and great harm. However, the existing AI chat platforms have not developed any relevant software or programs for PSD patients. Given that the chatbot function in the "Douba" software is relatively mature and can flexibly modify the corresponding intelligent agent according to user needs, this study intends to appropriately supplement and optimize the AI agent in the "Douba" software to explore the effect of the chatbot in the software in alleviating the symptoms of PSD patients.

Outcome Measures

Primary Outcomes (1)

  • Depression assessment

    Use the PHQ-9 scale,The sensitivity of this scale in diagnosing depression was 0.82, and the specificity was 0.87. The PHQ-9 scale collects information on the degree to which the evaluated individuals are troubled by different depressive symptoms, including loss of interest, low mood, sleep disorders, feeling tired, changes in appetite, poor self-perception, lack of concentration, slow movements or irritability, and suicidal thoughts. The score for each item ranges from 0 (none at all) to 3 (almost every day), and the total score ranges from 0 to 27. The higher the score, the more severe the symptoms.
