Abstract
- The aims of this study are to demonstrate the reliability and the validity of the Korean version of Behavioral Dyscontrol
Scale (BDS-K) and to present the normative values of BDS-K among the Korean elderly. The BDS-K was administered in a
standardized manner to 1,389 healthy volunteers aged over 65 years recruited from the community. The elderly with serious
neurological, medical or psychiatric disorders were excluded using screening tests. BDS-K showed good internal consistency
(Cronbach's alpha=0.812), test-retest reliability (r=0.88) and inter-rater reliability (r=0.99). Age and educational level were
found to affect BDS-K score. Based on this result, normative values of BDS-K were calculated by age and educational level. The
validity of the BDS-K were demonstrated in comparison with MMSE-KC (r=0.72). BDS-K is reliable and valid instrument
for measuring executive function of the elderly. The normative values suggested by this study can be widely used as reference
values to objectively interpret BDS-K scores of the Korean elderly.
