Objective:
Prospective memory involves remembering to complete a planned intention in the future. People routinely use compensatory strategies such as written notes and alarms to aid their prospective memory. The purpose of this study was to evaluate the effect of compensatory strategies on a performance-based prospective memory task in an older adult population with subjective cognitive concerns (SCC), a known risk factor for Alzheimer's disease.
Participants and Methods:
Participants included 162 older adults with SCC (age M=72.98, SD=7.70; education M=15.63, SD=2.22; 80% female, 89% White). The Royal Prince Alfred Prospective Memory Test (RPA-ProMem) was used to evaluate short- and long-term, time- and event-based prospective memory (4 tasks total). Participants were instructed to “use any techniques that you think might help you remember” the task. Tasks received a score ranging from 0 (worst possible) to 3 (best possible). For both the short- and long-term tasks, examiners tracked observed strategies participants put into place immediately after instructions were read (e.g., placed note in visible location, referred to clock). For short-term tasks, examiners also tracked strategies they observed participants actually use at the time of task completion (e.g., referred to written note). Because long-term tasks were completed outside of the session (i.e., call when arrive home, send postcard one week from session date), strategies actually used could not be observed.
Results:
Overall, participants performed best on the long-term event-based task (Mdn = 3.0), followed by short- and long-term time-based tasks (both Mdn=2.00), and worst on the short-term event-based task (Mdn= 1.00). There were significant differences between each task performance with the exception of the time-based tasks (Zs=0.88-4.72; ps=<0.001-0.38). Unexpectedly, participants put significantly more strategies into place for short-term (M=1.5, 95.7% used a strategy) than long-term (M=1.11, 90.1% used a strategy) tasks (p<0.001). For short-term tasks, participants utilized significantly fewer strategies at time of task completion then initially put in place and utilized significantly fewer strategies at time of task completion for event-based (M=0.53, just 50% of participants used a strategy) compared to time-based task (M=1.23, 89.5% of participants used a strategy). Whether a person used a strategy at the short-term event-based task completion was a significant predictor of prospective memory accuracy (OR=4.62, p<.002). Examination of individual compensatory strategies revealed that referring to a written note at time of task completion was the only significant predictor of the short-term event-based task. Compensation remained a significant predictor when cognition was entered into the model (which was also a significant predictor at p=0.05). Other than global cognition for the short-term event-based task, there were no additional cognitive predictors of task outcome or compensation.
Conclusions:
Individuals with SCC can complete longer-term prospective memory tasks, particularly those that are event based. In contrast, they have trouble recalling shorter-term event-based tasks unless compensatory strategies are utilized at the time of task execution. As such, individuals with cognitive concerns may benefit from compensation training to enhance prospective memory outcome, particularly for short-term event-based tasks.
