Digital Phenotyping of High-Risk Gaming Behavior Using Wearable Devices.
Article in Alpha psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Gaming addiction is a serious mental health issue. Early identification of high-risk gaming behaviors (HRGB) is crucial for prevention, yet research using wearable data for detection remains limited. This study analyzed the temporal dynamics of gaming behavior and health indicators using 28-day summary statistics derived from longitudinal data in young adults with HRGB, thereby providing a basis for gaming disorder prevention and intervention. Methods: This 28-day longitudinal study employed a self-designed system implemented on the Huawei Research Platform for participant recruitment and data collection. Participants completed daily mobile app questionnaires between 18:00 and 23:00 assessing gaming time, mood, and sleep, while a smart band continuously collected physiological and activity data. Emotional states were assessed weekly using the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7. Machine learning models were applied to compare the predictive performance of active (self-report), passive (wearable), and combined data in identifying HRGB, and to determine key predictive factors relevant for intervention. Results: The final sample comprised 37 participants in the HRGB group and 23 in the non-HRGB group. Significant between-group differences were observed across multiple indicators. Combined data yielded the highest area under the receiver operating characteristic curve (AUROC) in five of six models (logistic regression: 0.86 vs 0.81). Wearable-derived data enhanced early classification of HRGB, with depression severity (PHQ-9), heart rate, and sleep metrics emerging as potential markers. A one-standard-deviation increase in PHQ-9 scores was associated with a 3.51-point increase in Gaming Disorder Screening Scale (GDSS) scores (89% credible interval [CrI], 1.85-5.20), while a higher heart rate index was associated with a 1.36-point increase in GDSS scores (89% CrI, 0.13-2.60). The population attributable fraction was 15.51% for PHQ-9. Conclusions: Wearable data enhances early HRGB classification. PHQ-9, heart rate, and sleep metrics are key predictors, showing clinical utility.
