Purpose: The purpose of this study was to evaluate the psychometric properties of the Korean version of the Alzheimer’s Disease KnowledgeScale (ADKS-K) to determine its applicability to Korean adults.
Methods: Cross-cultural validity was performed according to Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN). The Kuder-Richardson Formula 20 for internalconsistency and Intraclass Correlation Coefficient (ICC) for test-retest reliability were conducted. Content validity, criterion related validityand construct validity were evaluated. The Classical Test Theory (CTT) model and the Item Response Theory (IRT) model were applied inperforming the item analysis.
Results: The KR 20 was .71, and the ICC was .90, indicating that the ADKS-K has internal consistency andstability reliability. Thirty items of the ADKS-K had significant Content Validity Ratio (CVR) values, i.e., mean of 0.82 and range of 0.60~1.00. Mean item difficulty and discrimination indices calculated by TestAn program were 0.63 and 0.23, respectively. Mean item difficulty anddiscrimination indices calculated by BayesiAn program were -0.60 and 0.77, respectively. These tests indicate that ADKS-K has an acceptablelevel of difficulty and discriminating efficiency.
Conclusion: Results suggest that ADKS-K has the potential to be a proper instrumentfor assessing AD knowledge in Korean adults.
