<p>This study aimed to employ network analysis to investigate the interaction between two prevalent mental disorders: Major Depressive Disorder (MDD) and Social Anxiety Disorder (SAD). The primary objective was to identify symptoms exhibiting the highest centrality indices within the networks of each disorder. Furthermore, the study sought to uncover bridge symptoms that may contribute to the observed comorbidity between MDD and SAD. A cross-sectional dataset was gathered from 481 participants, comprising 329 women (68.4%) and 152 men (31.6%). The results indicated that within the MDD network, symptoms such as Past failure, Difficulty concentrating, Pessimism, Loss of energy, and Tiredness or fatigue were particularly significant. In contrast, the SAD network revealed that Fear of talking to strangers, Fear of parties and social events, Avoidance of situations in which one is the center of attention, and Avoidance of attending parties emerged as the most critical symptoms. Additionally, the analysis identified Loss of interest, Fear of authority, and Avoidance of situations in which one is the center of attention as the most prominent bridge symptoms linking the MDD and SAD networks. These findings underscore the importance of addressing these symptoms in clinical prevention and treatment programs for the respective disorders.</p>
