Despite significant research done on youth experiencing homelessness, few studies have examined movement patterns and digital habits in this population. Examining these behaviors may provide useful data to design new health intervention models for homelessness. Specifically, passive collection (data collected without extra steps a user) insights into lived experience user needs putting an additional burden homelessness inform design.The objective of study was explore mobile phone Wi-Fi usage GPS location among Additionally, we further the relationship between as correlated with depression posttraumatic stress disorder (PTSD) symptoms.A total 35 adolescent young adult participants were recruited from general community that included installing sensor acquisition app (Purple Robot) up 6 months. Of participants, 19 had sufficient conduct analyses. At baseline, completed self-reported measures (Patient Health Questionnaire-9 [PHQ-9]) PTSD (PTSD Checklist DSM-5 [PCL-5]).

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 Prior research has shown that changes in seasons and weather can have a significant impact on depression severity. However, findings are inconsistent across populations, the interplay between weather, behavior, not been fully quantified. This study analyzed real-world data from 428 participants (a subset; 68.7% of cohort) RADAR-MDD longitudinal mobile health to investigate seasonal variations (measured through remote validated assessment - PHQ-8) examine potential dynamic changes, physical activity (monitored via wearables), The clustering PHQ-8 scores identified four distinct severity: one stable trend three varying patterns where peaks different seasons. Among these patterns, within had oldest average age (p = 0.002) lowest baseline score 0.003). Mediation analysis assessing indirect effect showed differences among with affective responses weather. Specifically, temperature day length significantly influenced severity, which turn impacted levels < 0.001). For instance, negative correlation severity temperature, 10°C increase led total daily step count rise 655.4, comprised 461.7 steps directly due itself 193.7 because decreased depressive (1.9 decrease PHQ-8). In contrast, for those positive correlation, 262.3-step rise; however, it was offset by 141.3-step increased (2.1 higher temperatures, culminating an insignificant overall 121 steps. These illustrate heterogeneity individuals' underscoring necessity personalized approaches help understand environmental factors effectiveness behavioral treatments.
