As stroke mortality has declined, a growing number of stroke survivors are returning to the community. Most survivors continue to experience functional limitations in their day-to-day lives. Research has focused on neurocognitive impairment (NCI) as an important driver of functional limitation. However, the contribution of NCI to functional limitation is not well characterized, with existing research showing no consistent relationships.
The researchers will use Ecological Momentary Assessment (EMA) as a technology-based ambulatory assessment to prospectively measure daily life activities and behavioral factors among 115 stroke survivors. In comparison to standard clinic-based assessments, EMA allows for real-time, repeated, within-person sampling of daily function, including participation in cognitive, social, physical, and passive leisure activities in real-world environments. EMA also assesses time spent in, and performance appraisals of, daily activities, as well as time-varying behaviors to understand dynamic relationships among study constructs and uncover within-person trends over time. The researchers will focus on variability in depressed mood and quality of life among stroke survivors, and social support, a protective factor with a potential buffering effect on daily function and mood.
Their pilot study has demonstrated strong support for the acceptability of mobile device use for stroke rehabilitation, and the researchers have developed an EMA daily function survey tailored for stroke survivors which they will use in this study to establish the most pertinent future treatment targets. Goals of this study are to determine both treatment targets and how and when to intervene to enhance stroke survivors’ daily function.
There are two main aims:
Aim 1: Use EMA to compare patters of daily function between survivors with and without NCI, and determine which aspects of NCI have greater effects on daily function.
Aim 2: Determine the impact of EMA-measured depressed mood and social support in explaining the temporal associations between NCI and daily function.
