Network comparisons by gender were conducted to evaluate global and local differences.</p> <p>Results</p><p>The network revealed multiple inter-domain associations, particularly negative relationships between mental well-being and symptoms of depression, anxiety, negative stress, and psychological inflexibility. Items reflecting self-evaluation and emotional well-being consistently emerged as the most central elements in the network across centrality metrics.

Gender-based comparisons indicated overall structural similarity between networks, although differences were observed in the strength of specific connections.</p> <p>Conclusions</p><p>Network analysis identified central elements linking mental well-being with psychological distress and inflexibility in a population seeking online psychological support.
