Reliability and Validity of the Korean Version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K) / 신경정신의학

ABSTRACT

OBJECTIVES: This study was conducted to evaluate the reliability and the validity of the Korean version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K). METHODS: The subjects were 55 schizophrenic patients between ages of 26 and 58 who were recruited from the psychiatric unit of the university hospital and the out-patient clinic. The SUMD-K and insight scale of PANSS were applied to the patients. RESULTS: The range of inter-rater (Spearman's rho) of the general items of SUMD-K were .97-. 98 on the current illness and .58-.98 on the past illness. The correlation coefficient between the sum and the general items of the SUMD-K showed high scores. The concurrent validity between SUMD-K and insight item of PANSS was high (scores between .59-.96). However, the reliability and the validity of the attribution items of symptoms showed low scores compared to the current symptoms. CONCLUSION: The SUMD-K was confirmed in its reliability and validity. It can be a useful clinician-rating scale for evaluating insight in schizophrenic patients as well as patients with other neuropsychiatric conditions.
