Do PDAs enhance the organization and memory skills of students with cognitive disabilities?
The project studied the on-time behavior of 35 students with intellectual disabilities (ID) or traumatic brain injury (TBI) under three conditions ? times and tasks list, paper planner, and two different personal data assistants (PDAs). Students participated for two 4-week periods, receiving one morning reminder during Period 1 and no reminders during Period 2. Students were on time more often using a PDA compared to a list (p < .024) or a planner (p < .002). Students were on time 50% more often in Period 1 with a single daily morning reminder as compared to no reminder across all conditions. When applying results, clinicians and researchers should note that only the alarm function prompting on-time behavior was studied, and the influence of the small sample size and short time frame. Future researchers will find a framework for studying PDAs and cell phones with larger samples, over longer time periods, and with a wider range of functions. ? 2008 Wiley Periodicals, Inc
