Key Points

This study aims to clarify the pathways linking psychological factors to social media addiction (SMA) through cognitive and behavioral mechanisms.
Cross-sectional survey of 258 active social media users
Examined associations using structural equation modeling (SEM)
Investigated psychological predispositions like boredom proneness, social comparison, and anxiety with mediators such as information overload and social media stalking.
Boredom proneness linked to SMA via information overload (β = 0.319, 95% CI [0.209, 0.455]) and social media stalking (β = 0.027, 95% CI [0.003, 0.071])
Social comparison impacted SMA through information overload (β = 0.091, 95% CI [0.005, 0.199]) and social media stalking (β = 0.160, 95% CI [0.071, 0.278])
Anxiety showed no significant paths to SMA via either mediator (β = 0.054, 95% CI [−0.033, 0.153]).

Abstract

Background: While social media enhances information accessibility and connectivity, excessive use has prompted research into social media addiction (SMA). However, pathways linking psychological stimuli to addictive behaviors remain unclear. This study examined how boredom proneness, social comparison, and anxiety relate to SMA through two mechanisms: information overload and social media stalking. Within the Stimulus–Organism–Response (S-O-R) framework, this research explains how psychological predispositions influence SMA through cognitive and behavioral mechanisms. Methods: A cross-sectional survey of 258 active social media participants examined associations between psychological predispositions and SMA. Structural equation modeling (SEM) was applied to examine the hypothesized model, with boredom proneness, social comparison orientation, and anxiety as internal stimuli, and information overload and social media stalking as mediators. Results: Boredom proneness and social comparison were not directly associated with SMA but showed significant indirect associations through both mediators. Boredom proneness was linked to SMA via information overload (β = 0.319, 95% CI 0.209, 0.455) and social media stalking (β = 0.027, 95% CI 0.003, 0.071). Similarly, social comparison was related to SMA through information overload (β = 0.091, 95% CI 0.005, 0.199) and social media stalking (β = 0.160, 95% CI 0.071, 0.278). In contrast, anxiety demonstrated no significant indirect associations through either information overload (β = 0.054, 95% CI −0.033, 0.153) or social media stalking (β = 0.021, 95% CI −0.020, 0.079). Conclusions: This study identifies two pathways linking psychological predispositions to SMA: cognitive strain and habitual monitoring. Distinguishing these mechanisms clarifies how addictive patterns develop and supports interventions targeting information processing burden and habitual social media monitoring.
