Mei Tian,1 Qiulian Xing,2 Xiao Wang,2 Xiqing Yuan,2 Xinyu Cheng,2 Yu Ming,2 Kexin Yin,2 Zhi Li,2 Peng Wang2 1Library, Shandong Normal University, Jinan, People’s Republic of China; 2School of Psychology, Shandong Normal University, Jinan, People’s Republic of ChinaCorrespondence: Zhi Li, School of Psychology, Shandong Normal University, Jinan, People’s Republic of China, Email [email protected]: With the rise of big data, deep learning neural networks have garnered attention from psychology researchers due to their ability to process vast amounts of data and achieve superior model fitting. We aim to explore the predictive accuracy of neural network models and linear mixed models in tracking data when subjective variables are predominant in the field of psychology. We separately analyzed the predictive accuracy of both models and conduct a comparative study to further investigate. Simultaneously, we utilized the neural network model to examine the influencing factors of problematic internet usage and its temporal changes, attempting to provide insights for early interventions in problematic internet use.Patients and Methods: This study compared longitudinal data of junior high school students using both a linear mixed model and a neural network model to ascertain the efficacy of these two methods in processing psychological longitudinal data.Results: The neural network model exhibited significantly smaller errors compared to the linear mixed model. Furthermore, the outcomes from the neural network model revealed that, when analyzing data from a single time point, the influences of seventh grade better predicted Problematic Internet Use in ninth grade. And when analyzing data from multiple time points, the influences of sixth, seventh, and eighth grades more accurately predicted Problematic Internet Use in ninth grade.Conclusion: Neural network models surpass linear mixed models in precision when predicting and analyzing longitudinal data. Furthermore, the influencing factors in lower grades provide more accurate predictions of Problematic Internet Use in higher grades. The highest prediction accuracy is attained through the utilization of data from multiple time points.Keywords: problematic internet use, junior high school students, neural network model, linear mixed model
