Passive mobile sensing provides opportunities for measuring and monitoring health status in the wild outside of clinics. However, longitudinal, multimodal sensor data can be small, noisy, incomplete. This makes processing, modeling, prediction these challenging. The small size set restricts it from being modeled using complex deep learning networks. current state art (SOTA) tackles sets following a singular modeling paradigm based on traditional machine (ML) algorithms. These opt either user-agnostic approach, making model susceptible to larger degree noise, or personalized where training individual alludes more limited set, giving rise overfitting, therefore, ultimately, having seek trade-off by choosing 1 2 approaches reach predictions.

Abstract Background The use of digital biomarkers through remote patient monitoring offers valuable and timely insights into a patient’s condition, including aspects such as disease progression treatment response. This serves complementary resource to traditional health care settings leveraging mobile technology improve scale lower latency, cost, burden. Objective Smartphones with embedded connected sensors have immense potential for improving various apps (mHealth) platforms. capability could enable the development reliable from long-term longitudinal data collected remotely patients. Methods We built an open-source platform, RADAR-base, support large-scale collection in studies. RADAR-base is modern platform around Confluent’s Apache Kafka scalability, extensibility, security, privacy, quality data. It provides study design setup active (eg, patient-reported outcome measures) passive phone sensors, wearable devices, Internet Things) capabilities feature generation behavioral, environmental, physiological markers). back end enables secure transmission scalable solutions storage, management, access.

Abstract Passive smartphone measures hold significant potential and are increasingly employed in psychological biomedical research to capture an individual's behavior. These involve the near-continuous unobtrusive collection of data from smartphones without requiring active input participants. For example, GPS sensors used determine (social) context a person, accelerometers measure movement. However, utilizing passive presents methodological challenges during analysis. Researchers must make multiple decisions when working with such measures, which can result different conclusions. Unfortunately, transparency these decision-making processes is often lacking. The implementation open science practices only beginning emerge digital phenotyping studies varies widely across studies. Well-intentioned researchers may fail report on some due variety choices that be made. To address this issue enhance reproducibility studies, we propose adoption preregistration as way forward. Although there have been attempts preregister template for registering currently missing. This could problematic high level complexity requires well-structured template. Therefore, our objective was develop easy use understandable researchers. Additionally, explain provide resources assist making informed regarding collection, cleaning, Overall, aim researchers' explicit, transparency, elevate standards measures.

Abstract Background Smartphone-based digital phenotyping enables potentially clinically relevant information to be collected as individuals go about their day. This could improve monitoring and interventions for people with Major Depressive Disorder (MDD). The aim of this systematic review was investigate current features methods used in MDD. Methods We searched PubMed, PsycINFO, Embase, Scopus Web Science (10/11/2023) articles including: (1) MDD population, (2) smartphone-based features, (3) validated ratings. Risk bias assessed using several sources. Studies were compared within analysis goals (correlating depression, predicting symptom severity, diagnosis, mood state/episode, other). Twenty-four studies (9801 participants) included. Results achieved moderate performance. Common themes included challenges from complex missing data (leading a risk bias), lack external validation. Discussion made progress towards relating phenotypes clinical variables, often focusing on time-averaged features. investigating temporal dynamics more directly may beneficial patient monitoring.

Abstract Background Brain related disorders are characterized by observable behavioral symptoms, for example social withdrawal. Smartphones can passively collect data reflecting digital activities, such as communication app usage and calls. This is collected objectively in real time, avoiding recall bias, may therefore be a useful tool measuring behaviors to functioning. Despite promising clinical utility, analyzing smartphone challenging datasets often include range of missingness-prone temporal features. Objective Hidden Markov Models (HMMs) provide interpretable, lower-dimensional representations data, allowing missingness. We aimed investigate the HMM method modeling time series data. Methods applied an aggregate dataset measures designed assess phone-related functioning healthy controls (HCs), participants with schizophrenia, Alzheimer’s disease (AD) memory complaints. trained on subset HCs (n=91) selected model socially “active” “inactive” states, then generated hidden state sequences per participant calculated their “total dwell time”, i.e. percentage spent active state. Linear regression models were used compare total available measures, logistic was times between diagnostic groups HCs. primarily report results from two-state but also verified HMMs more whole dataset. Results identified lower AD (n=26) versus withheld (n=156) (odds ratio=0.95, FDR corrected P <.001), well complaints (n=57) ratio=0.97, =0.004). The result very robust across variations, whilst less robust. observed interaction group when predicting (FDR =0.02). No significant relationships regarding schizophrenia (n=18).

Poor mental health is a global concern, with the World Health Organization reporting that one in eight people suffer from disorder. Identification and treatment are hampered by limited access to care inadequate insurance coverage. Digital technologies, such as smartphones, offer promising tools for improving through continuous monitoring timely intervention.
