Both groups will receive treatment as usual(TAU) provided by the clinical team, including medication, exercise, and psychotherapy. Robot-assisted intelligent rehabilitation treatment will be delivered to participants in the testing group through an addiction prevention and relapse intervention intelligent system.

Participants in the treatment-as-usual group were offered standard treatment at the mental health hospitals, which consisted of group and/or individual therapy, as determined by the clinical team.

Participants assigned to this condition were offered 10 individual sessions of robot-assisted rehabilitation treatment, delivered by the Robot-assisted rehabilitation intelligent system. The system contains 10 core cognitive-behavioral therapy (CBT) skill topics (such as functional analysis, coping skills training, reviewing practice exercises, and explaining CBT concepts). A robot therapist demonstrates the target CBT skills and assigns homework to participants. The treatment framework is semi-structured through human-computer interaction. The forms of interaction include inquiries, statements, recommendations summaries, and knowledge assessments.

The primary outcome is patients' desire for alcohol,measured by Visual Analogue Scale(VAS).
