About
Loss of independence, cognitive decline, and difficulties in everyday function are areas of great concern for older adults and their families. From a public health perspective, successful efforts that enable older adults to age within their homes, as compared to nursing homes, will save an estimated $80 billion dollars per year. Cognitive training is one intervention that maintains cognition, everyday function, and health. Although clearly an important and effective intervention, the mediators, or mechanisms, underlying this program are unknown. Our overall objective is to assess the cognitive and psychosocial factors within daily life that account for the transfer of one form of cognitive training to everyday function. This exploratory double-blind trial will randomize older adults to 20 hours of cognitive training or cognitively stimulating activities. The investigators will assess cognitive and psychosocial factors before, during, and after training within daily life. The investigators will then compare such factors and assess how they impact the transfer of cognitive training to everyday functioning. The investigators will also include an eligible sub group of the EFIT participants who will have functional MRI brain scans and sleep evaluation using the Sleep Profiler, a clinically approved device, at pre and post brain training. The investigators will also monitor daily activity in this sub group using FitBIt watches.
Our central hypothesis is that improvements in daily processing speed and attention, key components of higher order cognitive functions, will have the strongest relationship with everyday function changes. This exploratory study is the first of its kind and will be used to provide important data relevant to a future larger randomized controlled trial examining mediators of cognitive training in a representative sample of adults. Additionally, all data collection, with the exception of MRI, can be completed remotely within the participant's home. This information will assist in the future development of more effective home- and community-based interventions that maintain everyday function.
Full description
The EFIT study is a randomized clinical trial to explore moderators and mechanisms underlying the transfer of one cognitive training program to maintained cognition and everyday function. 100 participants will complete three traditional assessments of cognitive, psychosocial, and lifestyle assessments on a study-provided laptop at baseline, post-test, and three-month follow-up. Across this study period, participants will complete daily cognitive, psychosocial, and health assessments using a study-provided smartphone. Between baseline and post-test, participants will be randomized to one of two arms: cognitive training or an active control. Both groups will complete 20 hours of activities on the study-provided laptop across a ten week period.
A subsample of 40 participants will also complete three additional measures. First, they will be provided a FitBit and be asked to wear the FitBit across the study period. Second, sleep measures will be obtained across two nights at baseline and post-test using an at home sleep monitor, which is clinically approved, and evaluated by a physician specializing in sleep. Finally, this subsample will also complete a fMRI session at baseline and posttest.
Except for the fMRI sessions, all data collection is complete remotely within the participants' homes.
