Abstract

Objective Current measurements of cognitive functioning are time-consuming and costly, often done as point-in-time assessments. We examined the feasibility and acceptability of six newly developed smartphone-based mobile cognitive tests (MCTs), completed in the real-world, among persons with bipolar disorder (BD) and healthy controls (HC). Methods Thirteen community-dwelling participants (seven BD and six HC), aged 18-65, completed in-person neurobehavioral assessments at baseline and our MCTs three times daily for the following 14 days. The MCTs measure cognition in the following domains: reaction time, executive functions, attention, processing speed, working memory, and learning and memory. Our protocol delivered 1-2 MCTs per session, and each test was only administered once daily. Timing of the MCTs was adjusted according to individual sleep/wake schedules. Results MCT adherence was, on average, high (82.38%). The two groups did not differ in terms of adherence (p = 0.45, 95% CI = -29.51, 13.96) or average completion time (5.21 mins, SD = 1.54 min per each assessment period; t(11) = 1.12, p = .29, 95% CI = -0.91, 2.81). There was no relationship between age and adherence (r = .296, p = .326). Acceptability was measured at follow-up via a Likert-scale rating from 0 = not at all to 4 = very much; mean likeability was high (M = 3.0, SD = 1.28). Most participants noted a high willingness to complete additional MCT testing in the future. Conclusion Our preliminary findings indicate mobile cognitive testing is feasible and accepted among bipolar disorder and comparison participants. The implications of using smartphone-based MCTs are far reaching, including increased visibility of cognitive changes over time as well as examining real-time temporal relationships between cognition and other lifestyle and environmental factors.

Objective: Current measurements of cognitive functioning are time-consuming and costly, often done as point-in-time
assessments. We examined the feasibility and acceptability of six newly developed smartphone-based mobile cognitive tests
(MCTs), completed in the real-world, among persons with bipolar disorder (BD) and healthy controls (HC). Methods: Thirteen
community-dwelling participants (seven BD and six HC), aged 18-65, completed in-person neurobehavioral assessments at
baseline and our MCTs three times daily for the following 14 days. The MCTs measure cognition in the following domains:
reaction time, executive functions, attention, processing speed, working memory, and learning and memory. Our protocol
delivered 1-2 MCTs per session, and each test was only administered once daily. Timing of the MCTs was adjusted according
to individual sleep/wake schedules. Results: MCT adherence was, on average, high (82.38%). The two groups did not differ in
terms of adherence (p =0.45, 95% CI =-29.51, 13.96) or average completion time (5.21 mins, SD =1.54 min per each
assessment period; t(11) =1.12, p =.29, 95% CI =-0.91, 2.81). There was no relationship between age and adherence
(r =.296, p =.326). Acceptability was measured at follow-up via a Likert-scale rating from 0 =not at all to 4 =very much;
mean likeability was high (M =3.0, SD =1.28). Most participants noted a high willingness to complete additional MCT testing
in the future. Conclusion: Our preliminary findings indicate mobile cognitive testing is feasible and accepted among bipolar
disorder and comparison participants. The implications of using smartphone-based MCTs are far reaching, including increased
visibility of cognitive changes over time as well as examining real-time temporal relationships between cognition and other
lifestyle and environmental factors.
