Research on Social Work Practice, Ahead of Print.
Objectives: To facilitate research on digital hoarding in China, this study evaluated the psychometric properties of the Digital Hoarding Scale (DHS). Methods: A total of 618 participants were recruited through an online survey. The factorial structure, measurement invariance (MI), reliability, and validity of the DHS were tested. Results: The Chinese version of DHS was best represented by a bifactor exploratory structural equation modeling representation, which contains one general factor and three specific factors. The MI of the DHS was established across gender and age groups. Reliabilities of the specific and general factors were demonstrated by high values of omega coefficients. Moreover, the criterion validity was supported by the positive associations between DHS and physical hoarding disorder, obsessive-compulsive disorder, and anxiety. Conclusions: The DHS is a reliable tool for future studies investigating digital hoarding in Chinese.
