Prospective memory is the ability to remember to do something in the future and it is essential to every-day functional independence. Traumatic brain injury is associated with frequent and persistent prospective memory deficits. This study presents a review and meta-analysis investigating the effects of task parameters on prospective memory performance of individuals with TBI. Individual studies using continuous behavioural measures of prospective memory with a sample of adults with TBI and matched controls were included. Consistent with previous research, a random effects meta-analysis indicated that TBI groups demonstrated lower prospective memory performance than control groups (d = 1.10, SE = 0.12, 95 CI = 0.86-1.34). In addition, we found that type of prospective memory cue, saliency of cues, and complexity of the ongoing task significantly moderated the difference in prospective memory performance between TBI and control groups. These findings suggest that prospective memory task parameters should be considered in the assessment of prospective memory in individuals with cognitive impairment. In addition, considering the influence of these task parameters would be useful to develop effective compensatory strategies to reduce prospective memory failures.
