The relationship between online compulsive buying and internet addiction: an investigation on their phenomenological overlap and shared mechanisms in chinese university students
摘要
Online compulsive buying (OCB) has been conceptualized as a type of internet addiction (IA). However, it could also be related yet distinct from the general overuse of the Internet. This study aimed to examine the phenomenological overlap between OCB and IA, and explore their shared and unique associations with the predisposing (psychopathologies and loneliness) and mediating (coping strategies) factors specified by the Interaction of Person‑Affect‑Cognition‑Execution model of IAs. In a sample of 609 university students (79.6% female), confirmatory factor analyses were performed to compare two bifactor-(S-1) models (a theoretically anchored variant of a traditional bifactor model) with their corresponding correlated-factor models and a single-factor model. Multivariate multiple regressions were conducted to examine the relationships between these risk factors and the general and specific factors of the final bifactor-(S-1) model. Results indicated that the bifactor-(S-1) model with a general factor anchored in IA and two specific factors representing residual variance in two OCB dimensions demonstrated good fit, yet underperformed the correlated-factor model. Moreover, its general factor explained less than 20% variance in OCB dimensions, suggesting limited phenomenological overlap. While the general factor correlated with various depressive symptoms and loneliness, the two specific factors of OCB were related to denial and dysthymia. These findings support the distinction between generalized IA and OCB. While treatments for generalized IA should target depression-related cognitive biases and loneliness, interventions for OCB should aim to overcome denial. Cognitive training that enhances executive functions may improve both conditions. Future investigations using longitudinal designs and representative samples are warranted. (250 words)
