Objective:

Cognitive fluctuations are prevalent among individuals with mood disorders. However, real-world cognitive fluctuations are often difficult to assess in traditional neuropsychological assessments that only take a snapshot of the individual's cognitive functioning. The purpose of this study was to examine the utility of a novel, naturalistic, smartphone-based go/no-go task to detect within-day fluctuations in reaction time and impulsivity associated with mood disorders in the wild.

Participants and Methods:

Participants with (n = 46; bipolar disorders = 5, depressive disorders = 41) and without (n = 17) mood disorders completed a go/no-go (GNG) task on their personal iPhones as part of a larger study. The GNG task consisted of “go” trials, in which participants were instructed to shake their phones as quickly as possible following a blue stimulus dot, and “no-go” trials, in which participants were to refrain from shaking their phone following a green stimulus dot. The accuracy of the response and reaction time were recorded. Participants also completed the Quick Inventory of Depressive Symptomatology (QIDS) at baseline. Linear mixed effects models were used to examine the effects of hour of the day and depression severity on incorrect responses to no-go trials (commission errors) and reaction time.

Results:

There was a significant difference in reaction time based on the trial type; incorrect no-go trials had faster reaction times than correct go trials, suggesting that accuracy on the no-go trials may be an index for impulsivity. Hour of the day had a significant quadratic effect on the accuracy of no-go trials and reaction time, such that participants tended to respond faster and less accurately in the afternoon compared to mornings and evenings, particularly on the no-go trials. Moreover, depression severity as determined by the baseline QIDS score had a significant linear effect on reaction time in that those who were more depressed had slower reaction times compared to those who were less depressed. Lastly, a practice effect was observed in no-go trials with improved trial accuracy following more completed GNG tasks; this effect, however, did not impact reaction time.

Conclusions:

We propose a novel, smartphone-based go/no-go task capable of being completed repeatedly in a naturalistic setting due to its short and gamified nature. This task is sensitive to the influence of time of day and depression severity on reaction time and impulsivity. Since cognitive performance is impacted by mood disorder symptoms, our GNG task could serve to monitor real-time fluctuations in aspects of cognition without increasing the time burden on these individuals.
