A randomised controlled crossover trial evaluating Television Assisted Prompting (TAP) for adults with acquired brain injury

Assistive technologies for cognition (ATC) provide an effective means to compensate for prospective memory failures among adults with acquired brain injury (ABI; de Joode, van Heugten, Verhey, & van Boxtel, 2010 de Joode, E., van Heugten, C., Verhey, F. and van Boxtel, M. 2010.

This study evaluated a novel ATC device, the Television Assisted Prompting (TAP) system, which provides audiovisual reminders at scheduled prospective times on a person's home television. A randomised, controlled crossover design evaluated task completion for two preferred, two non-preferred, and two structured experimental tasks among 23 adults with ABI between two conditions: TAP prompting or typical (TYP) practice, without TAP reminders. Main outcomes showed a significant advantage of prospective memory prompting (72% completion) over no prompting (43% completion) and higher task completion with TAP prompting for researcher-assigned experimental tasks (81%) compared to self-selected preferred (68%) or non-preferred (68%) tasks. Results are discussed in the context of ATC efficacy to support prospective memory prompting following ABI, with contributions and future directions for continued investigation of customisation of prompts to maximise task completion.
