Through a mixed-methods approach combining variable-centered moderated mediation and person-centered latent profile analysis (N = 4,216), we identify two critical mechanisms: (1) social anxiety substantially mediates the relationship between social media use and academic adjustment, accounting for a significant proportion of this association, and (2) social self-efficacy moderates this statistical mediation pathway. Person-centered analyses reveal four distinct digital engagement configurations: high-intensity high-efficacy (36%), moderate-high intensity high-efficacy (28%), moderate-low intensity high-efficacy (20%), and low-intensity low-efficacy (16%). Profile-specific statistical mediation analyses demonstrate differential associations across profiles, with the strongest indirect relationship in the low-intensity low-efficacy group and the weakest in high-intensity high-efficacy users. These findings challenge uniform-effect assumptions by demonstrating how psychological resources co-occur with usage intensity to create distinctive associative patterns. While cross-sectional data preclude causal inference, results suggest theoretical and practical implications for understanding configuration-specific relationships between social media engagement and academic functioning. This dual-analytical framework advances theoretical integration of psychological mechanisms and configurational patterns in digital learning environments, potentially informing future longitudinal investigations of adaptation processes in educational technologies.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">383-402</style></section></record></records></xml>
