Objectives: The aims of this study were to develop an instrument for detection of relapse in psychotic disorder and to validate the instrument.
Methods: A total of 55 outpatients with psychotic disorder (schizophrenia, schizoaffective disorder,bipolar disorder) and 46 of their caregivers were enrolled. We developed the Questionnaire for Relapse Assessment in Psychotic disorder (QRAP), a self/report inventory. The patients and caregivers drew up the QRAP at two different time points, ¡®current¡¯ and ¡®the best state during the past three months¡¯. In addition, we rated other established scales in order to evaluate psychotic and mood symptoms of patients. We divided patients into two groups, stable (n=30) and impending relapse (n=35) and evaluated the effectiveness of QRAP by calculating sensitivity and specificity.
Results: For all patients and caregivers, QRAP total score at ¡®current¡¯ was higher than ¡®the best state during the past three months¡¯ and showed significant positive correlation with other established scales. As expected, QRAP total score at ¡®current¡¯ in the impending relapse group was higher than that of the stable group. With cut off criteria 1, the QRAP demonstrated 80.0% sensitivity and 56.3% specificity in caregivers and effectively detected impending relapse.
Conclusion: The results of our study suggest the effectiveness of QRAP as an instrument for detection of relapse in patients with psychotic disorder.
