Key result
The K-DIA-S demonstrated high diagnostic accuracy for detecting any depressive disorder with an AUC of 0.896, which was significantly larger than that of the PHQ-9 (p=0.033).
Why the study?
The Depression in Old Age Scale is a new tool for assessing depression in the elderly, requiring validation of its Korean version and comparison against other screening questionnaires in medical settings.
Does the K-DIA-S accurately screen for depressive disorders in elderly outpatients compared to other established questionnaires?
Cross-Sectional (n=385)
Yes
Does the K-DIA-S accurately screen for depressive disorders in elderly outpatients compared to other established questionnaires?
Absolute Event Rate: 0.896% vs 0.86%
p-value: p=0.033
The K-DIA-S is a valid and reliable tool for screening depressive symptoms in elderly medically ill patients, showing comparable or slightly superior diagnostic accuracy to the SGDS and PHQ-9.
Supports K-DIA-S screening in elderly outpatients; leaves open prospective validation versus PHQ-9 before practice change.
OBJECTIVE: The Depression in Old Age Scale (DIA-S) is a new screening tool for assessing depression in the elderly. The primary aims of this study were to describe the validation of the Korean version of the DIA-S (K-DIA-S) and to compare its validity with that of other depression screening questionnaires used in elderly outpatients in medical settings. METHODS: A total of 385 elderly outpatients completed the K-DIA-S and underwent the Mini International Neuropsychiatric Interview to diagnose depressive disorders. Other measures included the 15-item short form of the Geriatric Depression Scale (SGDS), the 9-item depression module of the Patient Health Questionnaire (PHQ-9), and the Montgomery-Asberg Depression Rating Scale (MADRS). Reliability and validity tests, an optimal cutoff point estimate, and receiver operating characteristic curve analysis were performed to investigate the diagnostic validity of the K-DIA-S. Areas under the curves (AUCs) for the K-DIA-S, SGDS, and PHQ-9 were compared statistically. RESULTS: = 0.033). CONCLUSION: The present findings suggest that the K-DIA-S has good psychometric properties and is a valid and reliable tool for assessing depressive symptoms in elderly populations and medically ill patients.

Jung et al. (2019) conducted a cross-sectional in Depressive disorders (n=385). Korean version of the Depression in Old Age Scale (K-DIA-S) vs. PHQ-9 and SGDS was evaluated on Diagnostic accuracy (Area Under the Curve) for detecting any depressive disorder (95% CI 0.86-0.93, p=0.033). The K-DIA-S demonstrated high diagnostic accuracy for detecting any depressive disorder with an AUC of 0.896, which was significantly larger than that of the PHQ-9 (p=0.033).
