Study assessed the feasibility and validity of a mobile health (mHealth) system for conducting ecological momentary assessment (EMA) of mood-related symptoms after traumatic brain injury (TBI). EMA involves repeated assessment of individuals in real time, over time, in their natural environments and across different contexts, enabling a more comprehensive understanding of the frequency, intensity, and duration of both physical and emotional symptoms. An mHealth system was developed as a smartphone application specifically for individuals with TBI using previously validated tools for depressive and anxiety symptoms (Patient Health Questionnaire- 9, Generalized Anxiety Disorder-7). Feasibility was evaluated in 20 community-dwelling adults with TBI via an assessment of compliance, satisfaction, and usability of the smartphone application over an 8-week period. Results showed that participants correctly completed 73.4 percent of all scheduled assessments, demonstrating good compliance. Daily assessments took 52 minutes to complete. Participants reported high satisfaction with smartphone applications (6.3 of 7) and found them easy to use (6.2 of 7). Comparison of assessments obtained via telephone-based interview and EMA demonstrated high correlations (.81 to 0.97), supporting the validity of conducting these assessments via smartphone application in this population. EMA conducted via smartphone demonstrates initial feasibility among adults with TBI and presents numerous opportunities for long-term monitoring of mood-related symptoms in real-world settings.
