The longitudinal relationships between problematic smartphone use and anxiety symptoms among Chinese college students: A cross-lagged panel network analysis.

Anxiety and problematic smartphone use (PSPU) are prevalent issues among college students, and traditional research has tended to focus on cross-sectional data and grounded only in overall levels, thereby ignoring the complex interactions between the two over time. The development of network analysis methods has provided a new perspective for in-depth exploration of the relationship. This study aimed to explore the complex longitudinal interactions and specific pathways between problematic smartphone use and anxiety among Chinese college students from an internal specific symptom perspective. This study constructed a cross-lagged network model using longitudinal data on problematic smartphone use and anxiety symptoms in two waves of college students collected from 2022 to 2023 (N=741, M = 18.49, SD=0.81, 45.6 % male). The study found that anxiety symptoms and problematic smartphone use interacted with each other and had a vicious cycle of symptoms over time, with the effects of anxiety symptoms being more pronounced. "Feeling afraid" and "Uncontrollable worrying" had the most significant effects on the other symptoms, with "Impatient without the phone" and "Can't stand not having a phone" were more likely to be influenced by other symptoms. "Feeling afraid" may be a bridge symptom in the network to connect the anxiety and problematic smartphone use communities. The findings suggest that accurately intervening in the intrinsic link between problematic smartphone use and anxiety symptoms can combat the exacerbation of both problems simultaneously, resulting in more effective and comprehensive treatment.
