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><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Guadalupe de la Iglesia</style></author><author><style face="normal" font="default" size="100%">Alejandro Castro Solano</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">ACADEMIC ACHIEVEMENT OF COLLEGE STUDENTS: THE ROLE OF THE POSITIVE PERSONALITY MODEL</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">academic achievement</style></keyword><keyword><style  face="normal" font="default" size="100%">academic adjustment</style></keyword><keyword><style  face="normal" font="default" size="100%">personality traits</style></keyword><keyword><style  face="normal" font="default" size="100%">positive traits</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2019</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2019</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2019/457-1571384259.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">77</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This research aimed at testing an explicative model of academic achievement of college students. Positive personality traits were hypothesized as the main predictors. Mental health and academic adjustment were tested as mediator variables. This model intended to reflect the main hypothesis that academic achievement is multi-determined and non-intellectual variables play an important role in explaining it. Sample was composed of 256 college students of different majors. The results obtained highlighted the importance of differentiating subjective and objective academic achievement in terms of academic adjustment (AA) and grade point average (GPA), respectively. The explicative model that included positive traits as background variables confirmed the mediating role of mental health and AA in explaining GPA. Sprightliness was the most important predictor of academic achievement in comparison to the other positive traits studied. It is concluded that positive personality traits play an important role in academic outcomes. </style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">572-583</style></section></record></records></xml>
