Abstract
|
|
|
Objectives：To examine whether the psychotic patients report their symptoms adequately, we investigated the correlation between subjective and objective measurements of symptoms.
Methods：Forty eight patients with schizophrenia or related psychotic disorders who experienced prominent delusion and hallucination within 1 month were included. Scores of positive (PANSS-pos), negative (PANSS-neg), and depressive (PANSS-dep) domains of the Positive and Negative Syndrome Scale (PANSS) were compared with self-rating scales for given domains such as the Peters et al. Delusional Inventory (PDI-21), the Scale for the Subjective Experience of Negative Symptoms-Korean version (SENS-K), the Beck Depression Inventory (BDI), and the Symptom Checklist-90-Revision (SCL-90-R). Insight level was measured by the Scale to Assess Unawareness of Mental Disorder (SUMD).
Results：Significant correlations were found between the PANSS-neg and the SENS-K, and the PANSS-dep and self-rating depression measures. PANSS-pos showed significant correlation with the psychoticism factor of the SCL-90-R. Mostly, these correlations were not affected by insight level.
Conclusion：Psychotic patients, who suffered from delusions and hallucinations recently, were able to report negative and depressive symptoms adequately while they showed some discrepancies between subjective and objective measures on psychotic symptoms. Although these results support the reliability and validity of self-rating scales in psychotic patients, further study of selfreport measures of psychotic symptoms will be needed.
