Objective To observe the effect of group biofeedback in patients with residual schizophrenia (RS).

Methods A total of 127 patients with RS were selected as study objects, and randomly divided into control group (n=63) and observation group (n=64). The control group received routine nursing, and the observation group received group biofeedback based on the control group. The Positive and Negative Symptom Scale (PANSS), Personal and Social Performance Scale (PSP) and Self-awareness Inventory (SAI) Questionnaire (treatment compliance) scores were compared between the two groups.

Results After 12 weeks of intervention, the score of the positive symptoms, the score of negative symptoms and the total score of PANSS in the observation group were significantly lower than those in the control group (P < 0.05). The number of patients with PSP scores greater than 70 to 100 and greater than 30 to 70 in the observation group was significantly more than those in the control group, and the number of patients with PSP score of 0 to 30 was significantly less than that in the control group (P < 0.05). The SAI score of the observation group after intervention was significantly higher than that before intervention and control group, and the number of completed biofeedback therapy in the observation group was significantly more than that in the control group (P < 0.05).

Conclusion Group biofeedback can promote symptom relief and improve treatment compliance in patients with RS.
