Social interaction and drug attitude effectiveness in patients with schizophrenia.

This study aimed to explore the relationship between dosage of paliperidone and drug attitude, and also clarify the factors associated with drug attitude, using Intention-to-Treat (ITT) analysis. Three hundred thirty-one patients diagnosed with schizophrenia, who prescribed paliperidone between April 2008 and April 2009, from 10 hospitals in Taiwan were enrolled. By structural equation modeling, inpatient/outpatient status associated with occupation status, sex, and score on the Clinical Global Impression-Severity (CGIS) Scale. The score on the Personal and Social Performance (PSP) Scale associated with occupation status, inpatient/outpatient status, and the score on the CGIS Scale. The scores on the DAI-10 associated with the score on the PSP Scale and age. Good drug attitude and medication adherence significantly related to good social interaction. We should enhance the drug attitude and medication adherence of patients with schizophrenia who have poor social interaction to improve the outcome of schizophrenia.
