Effects of drug attitudes on treatment compliance and psychiatric symptoms of schizophrenia: an one year follow-up study / 中国神经精神疾病杂志

ABSTRACT

Objective To explore the effects of integrated treatment model (psychosocial interventions combined with drug therapy) in schizophrenia and analyze the influence of medication attitude on treatment compliance and psychiatric symptoms in different intervention models.Methods A total of 170 patients with schizophrenia were enrolled from 2012 to 2015.Patients were randomly divided into two groups:the integrated treatment group (86 patients) with drug therapy and psychosocial intervention,and the conventional drug treatment group (84 patients) with only drug intervention.Dug attitude inventory (DAI),self-awareness inventor (SAI),positive and negative symptoms scale (PANSS) were used to assess medication attitude,treatment compliance and clinical psychotic symptoms for all patients in the following 3 months,6 months and 12 months.Results Compared with medication-alone group,the integrated treatment group achieved significant improvement in psychiatric symptoms,including positive symptom and general psychopathology as well as significant reduction in scores in DAI and SAI (P＜0.05).In the conventional drug treatment group,the PANSS score was positively correlated with the increased score of DAI (β=0.31,P=0.02),which was mediated by the improvement in treatment adherence (β=0.18,P=0.18).There was no significant correlation between PANSS score and the increase score of DAI in the integrated treatment group(P=0.62).However,the increased score of SAI was positively correlated with the positive symptom of PANSS scale (r=0.31,P=0.01) and with the general psychiatric symptom scale (r=0.36,P＜0.01).Conclusion This study demonstrates that medication attitude can improve the treatment of mental symptoms by increasing compliance in the medication-only group.Symptom improvement is associated with improved compliance but not with medication attitudes in the integrated treatment model.
