Google Calendar: a new memory aid to compensate for prospective memory deficits following acquired brain injury

Prospective memory impairment is common following acquired brain injury (ABI) and intervention has proved challenging. The current treatment of choice involves using external memory aids as a method of compensation, with those incorporating active reminders proving most successful. In this paper we report findings of an investigation into the effectiveness of a novel external memory aid, Google Calendar. This aid incorporates active reminders and overcomes some of the limitations associated with existing aids. Twelve participants with ABI took part in the study incorporating a randomised control crossover within-subjects design, consisting of a 5-week baseline phase, followed by two 5-week intervention phases where either Google Calendar or a standard diary were used. Participants identified activities to target during the study and a family member monitored their success. Google Calendar was more effective than the diary in enhancing prospective memory performance. It also proved more popular, on account of its active reminders which helped trigger the retrieval of intentions, whilst reducing the need for monitoring. While further research is required to substantiate these initial findings, it is recommended that clinicians familiarise themselves with using Google Calendar, as it appears to offer additional potential in the management of prospective memory deficits following ABI.
