Abstract:
Objective:To investigate the efficacy of Naikan cognitive therapy(NCT)combined with medica-tion in improving depressive symptoms and sleep quality in patients with chronic schizophrenia.Methods:Patients were included if they met the following criteria:diagnosed with schizophrenia based on ICD-10 criteria,a disease course of ≥2 years,stable condition under maintenance antipsychotic medication,presence of depressive symptoms and sleep quality issues,and no use of antidepressants in the past two months.A total of 64 eligible patients were randomly assigned to the NCT group(n=32)or the mental health education(MEC)group(n=32).The interven-tion lasted 6 days,with 2 patients from each group dropping out.The Beck Depression Inventory-Ⅱ(BDI-Ⅱ)and Pittsburgh Sleep Quality Index(PSQI)were used to assess depressive symptoms and sleep quality.Results:After the intervention,the BDI-Ⅱ score difference(post-treatment score minus pre-treatment score)in the NCT group was significantly lower than that in the MEC group(P＜0.001).Similarly,the PSQI total score difference was also lower in the NCT group compared to the MEC group(P＜0.001).Conclusion:Adding Naikan cognitive therapy to routine medication treatment can effectively improve depressive symptoms and sleep quality in patients with chronic schizophrenia.
