Which statement best describes the relationship between DAST-20 and DAST-10?

Explanation:
These two tools are the same screening instrument family for detecting drug-use problems, and the key difference is how many items they include. DAST-20 has twenty yes/no items, while DAST-10 has ten. Because it contains more items, DAST-20 collects more information and offers a higher possible score, which can provide a more nuanced assessment. DAST-10 serves as a quicker, briefer screen when time is limited. They measure the same construct, so the extra items in DAST-20 simply extend the length and detail, rather than changing what they assess.
