We conducted a large-scale, two-wave longitudinal study (Wave 1:&amp;nbsp;&lt;em&gt;N&lt;/em&gt; = 69,115;&amp;nbsp;&lt;em&gt;M&lt;/em&gt; = 12.74 ± 2.25 years; 49.84% girls; Wave 2:&amp;nbsp;&lt;em&gt;N&lt;/em&gt; = 45,762;&amp;nbsp;&lt;em&gt;M&lt;/em&gt; = 12.98 ± 2.22 years; 50.53% girls; with 45,762 students participating in both waves) across a 6-month interval. A three-factor structure of adolescent values emerged: Collective Altruism, Individual Initiative, and Individual Hedonism. Results revealed distinct developmental trajectories: Collective Altruism declined slightly, while Individual Hedonism increased, both stabilizing around mid-adolescence (age~15)—a developmental inflection point in value orientation. Cross-lagged models demonstrated small but significant reciprocal positive associations between Collective Altruism, Individual Initiative, and well-being, while Individual Hedonism showed a small but significant negative association with subsequent well-being. These findings support the theoretical framework of&amp;nbsp;&lt;em&gt;contextually healthy values&lt;/em&gt;—value orientations that are culturally normative and developmentally adaptive. This study also provides valuable insights for promoting adolescent mental health and positive development in rapidly modernizing contexts.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record></records></xml>
