According to self-determination theory, intrinsic values foster personal and societal wellness, while extrinsic values detract from them. This study examined the developmental change/stability in intrinsic and extrinsic values from early to mid- and late adolescence and how these values relate to family SES. Three aspects of change/stability were examined: structures, rank-order stability, and mean level. An existing dataset from a multi-wave multi-cohort panel study was used involving 2,378 (Cohort 1) and 2,351 (Cohort 2) Korean adolescents. Across adolescence, value structure became more differentiated; rank-order stability increased; mean levels of intrinsic values remained stable, if not decreased; family SES was associated with higher levels of extrinsic values. These findings contribute to the cultural diversity of the existing knowledge on personality development.

根据自决理论，内在价值促进 个人和社会健康，而外在价值会减损它们。本研究考察 了从青春期早期到中期和晚期的内在和外在价值观的发展变化/稳定性，以及这些价值观 与家庭 SES 的关系。检查了变化/稳定性的三个方面：结构、等级顺序稳定性和平均水平。 来自多波多队列的现有数据集 小组研究涉及 2,378 名（队列 1）和 2,351 名（队列 2）韩国青少年。在整个青春期，价值结构变得更加分化；等级顺序稳定性增加；内在价值的平均水平保持稳定，即使没有下降；家庭 SES 与更高水平的外在价值相关。这些发现有助于现有人格发展知识的文化多样性。
