Supporting strategic processes can improve time-based prospective memory in the laboratory among older adults with HIV disease.

OBJECTIVE

Older adults with HIV disease demonstrate moderate deficits in time-based prospective memory (PM), which is the strategically demanding ability of remembering to perform a task at a specific time. Using theories from the PM literature, we hypothesized that supporting strategic processes would improve time-based PM in the laboratory among HIV+ older adults.

METHOD

One hundred forty-five HIV+ participants were randomly assigned to a control condition or an experimental group in which strategic processing was supported at encoding (i.e., implementation intentions and visualization), monitoring (i.e., content-free cuing), and/or cue detection (i.e., auditory alarm). The HIV+ control group and 58 seronegative participants completed two ongoing language tasks with a time-based PM requirement. The HIV+ experimental groups underwent counterbalanced time-based PM trials under both control and strategically supported conditions.

RESULTS

The HIV+ cue-detection group showed a large within-subjects improvement, which was strongly related to lower scores on separate clinical time-based PM measure and was accompanied by a large reduction in clock-checking behavior. Results also revealed a small within-subjects improvement in time-based PM in the encoding condition.

CONCLUSIONS

Supporting strategic encoding and cue-detection processes in the laboratory can improve time-based PM deficits in older HIV+ adults, which may inform the development of more naturalistic PM-based interventions to enhance health behaviors. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
