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.
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.
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.
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.

感染艾滋病毒的老年人在基于时间的前瞻性记忆(PM)方面表现出中度缺陷,这是一种在特定时间记住执行任务的具有策略性要求的能力。利用前瞻性记忆文献中的理论,我们假设支持策略性过程将改善艾滋病毒阳性老年人在实验室中的基于时间的前瞻性记忆。
145名艾滋病毒阳性参与者被随机分配到一个对照条件组或一个实验组,在实验组中,在编码(即执行意图和视觉化)、监测(即无内容提示)和/或线索检测(即听觉警报)方面支持策略性加工。艾滋病毒阳性对照组和58名血清阴性参与者完成了两项有基于时间的前瞻性记忆要求的正在进行的语言任务。艾滋病毒阳性实验组在对照条件和策略性支持条件下进行了平衡的基于时间的前瞻性记忆试验。
艾滋病毒阳性线索检测组在个体内部有很大改善,这与单独的基于临床时间的前瞻性记忆测量中的较低分数密切相关,并且伴随着看表行为的大幅减少。结果还显示,在编码条件下,基于时间的前瞻性记忆在个体内部有小幅改善。
在实验室中支持策略性编码和线索检测过程可以改善艾滋病毒阳性老年成年人基于时间的前瞻性记忆缺陷,这可能为开发更自然的基于前瞻性记忆的干预措施以促进健康行为提供信息。(PsycINFO数据库记录(c)2020美国心理学会,保留所有权利)
