Which DEOCS item measures alcohol impairment of memory?

• A. During the past 12 months, how often have you been unable to remember what happened the night before because you had been drinking?
• B. In the past month, how often have you attended mandatory training?
• C. How many days did you miss work due to illness?
• D. Do you prefer beer or wine?

Answer: (A)

This item measures whether alcohol use affects memory by asking if, in the past year, you have been unable to remember what happened the night before because you had been drinking. It directly targets memory impairment as a result of drinking, which is exactly what this question is designed to assess. The other options don’t address alcohol-related memory: one asks about attendance at mandatory training, another about illness-related absences, and the last about a preference for beer or wine.
