Assessment of productivity performance in men with HIV Associated Neurocognitive Disorder (HAND)
Judy L. Ranka, Christine Chapparo. Work, 2010-01-01
Topic: Risk, prevention and care in population studies
The participant demonstrated 28.6% mastery of the grocery shopping task. Performance was impacted on primarily by errors of accuracy and timing. Reasons for these errors centered on the participant's difficulties in applying cognitive strategies to perceive, recall, plan and perform the task. The PRPP System of Task Analysis shows promise in being able to identify errors in task mastery and the underlying cognitive strategy application errors that impact on mastery in people with HAND.

Key findings
- The participant demonstrated 28.6% mastery of the grocery shopping task.
- Performance was impacted on primarily by errors of accuracy and timing.
- Reasons for these errors centered on the participant's difficulties in applying cognitive strategies to perceive, recall, plan and perform the task.
- The PRPP System of Task Analysis shows promise in being able to identify errors in task mastery and the underlying cognitive strategy application errors that impact on mastery in people with HAND.
Why it matters
This single-participant study found that a man with HIV-associated neurocognitive disorder completed only 28.6% of a grocery shopping task, with errors in accuracy and timing. It suggests a task analysis system may help identify such errors, but it is a single case and does not test any treatment, cure, or prevention for Alzheimer's disease.
