Excessive smartphone use has recently attracted researchers’ attention. Previous studies have suggested that state anxiety and motivations are important predictors of excessive smartphone use. However, few studies have investigated how motivations and state anxiety interact with each other, and the subsequent impact on excessive smartphone use. In the current study, based on the Compensatory Internet Use theory, we analyzed the moderating role of state anxiety on the relationship between two types of motivations (i.e. entertainment and social interaction) and excessive smartphone use. Using the Smartphone Addiction Scale for College Students (SAS-C), Smartphone Usage Motivation Scale and State Anxiety Scale (S-Anxiety), we investigated 600 Chinese college students who identified themselves as smartphone users. Results indicated that: (1) for the high smartphone-use group, state anxiety moderates the relationship between entertainment and social interaction motivations and excessive smartphone use; (2) for the low smartphone-use group, state anxiety does not moderate the relationship between entertainment and social interaction motivations and excessive smartphone use. Our study emphasized the importance of psychological well-being variables (i.e. anxiety in this study) in facilitating excessive smartphone use, and may provide guidance for the design of interventions targeted at people suffering from excessive smartphone use.
