Heusser*†, Denton J. DeLoss†, Elena Cañadasand Titiimaea Alailima  \nAkili Interactive, Boston, MA, United States  \nDigital Therapeutics (DTx) are evidence-based software-driven interventions for the prevention, management, and treatment of medical disorders or diseases. DTx offer the unique ability to capture rich objective data about when and how a patient engages with a treatment. Not only can one measure the quantity of patient interactions with a digital treatment with high temporal precision, but one can also assess the quality of these interactions. This is particularly useful for treatments such as cognitive interventions, where the speciﬁc manner in which a patient engages may impact likelihood of treatment success. Here, we present a technique for measuring the quality of user interactions with a digital treatment in near-real time. This approach produces evaluations at the level of a roughly four-minute gameplay session (mission) . Each mission required users to engage in adaptive and personalized multitasking training. The training included simultaneous presentation of a sensory-motor navigation task and a perceptual discrimination task. We trained a machine learning model to classify user interactions with the digital treatment to determine if they were “using it as intended” or “not using it as intended” based on labeled data created by subject matter experts (SME) . On a held-out test set, the classiﬁer was able to reliably predict the SME-derived labels (Accuracy = . 94; F1 Score = . 94) . We discuss the value of this approach and highlight exciting future directions for shared decision-making and communication between caregivers, patients and healthcare providers. Additionally, the output of this technique can be useful for clinical trials and personalized intervention.  \nKEYWORDS  \ndigital therapeutics, engagement, machine learning, cognition, brain health  \nIntroduction  \nDigital mental health interventions target the prevention or treatment of mental health disorders and associated impairments (i.e., functional, affective, cognitive) delivered via a digital platform (e.g., web browser, mobile apps, text messaging, or virtual reality) (1) . They offer the potential to overcome availability and accessibility limitations, including geographical location and time (2–4) .  \nWhile there are thousands of digital interventions claiming to improve various aspects of mental health, many of them have never gone through clinical trials or regulatory scrutiny. Also, due to a number of factors, including fast growth of the industry and an absence of well-accepted standards, there are widely varying deﬁnitions of w","cbCaip3H8c5iLK4g","https://ap.wps.com/l/cbCaip3H8c5iLK4g","pdf",715219,1,6,"English","en",105,"# Introduction\n## Digital mental health and DTx\n## Engagement and why quality matters\n## Limits of adherence and retention measures","[{\"question\":\"What are digital therapeutics (DTx) and why do they matter for measuring engagement?\",\"answer\":\"DTx are evidence-based software-driven interventions that record objective data on when and how patients engage.
