Definition

An interviewer-administered test that measures the ability of the respondent to process and retrieve information associated with short-term memory.

Purpose

This measure tests a respondent’s total range of function with respect to working memory. It is therefore more specific and sensitive than a measure of global mental status and can be used to assess major problems in working memory as well as minor variations that may be a consequence of normal development and aging.

Selection Rationale

The Digit Span Test was selected because it is a widely used, validated protocol that requires less time to administer than similar instruments.
