Facilitating intrinsic aspirations remains a challenge in studies on self-determination theory. This article, comprising two studies, focuses on the development of an educational intervention that provides individuals with opportunities to consider their life aspirations. In Study 1, a total of 320 undergraduates participated in a survey designed to confirm the validity of the Japanese version of the Aspirations Index. The results showed that the scale had reasonable reliability and construct validity. Then, in study 2, we administered the program and tested its effectiveness for 42 undergraduate students (48 undergraduates for the comparison). The results of a generalized linear mixed model and mixed-design ANOVA indicated that the intervention successfully increased the participants’ intrinsic aspirations, but not their extrinsic aspirations. Additionally, from qualitative data, almost all participants reported deriving benefits from the intervention program and obtaining new perspectives on their career issues and intrinsic aspiring. Overall, we conclude that the proposed educational intervention may be a valid method of strengthening intrinsic aspirations of youth.

促进内在愿望仍然是自决理论研究中的一个挑战。本文包含两项研究，重点关注教育干预的发展，该干预为个人提供了考虑其人生抱负的机会。在研究 1 中，共有 320 名本科生参与了一项旨在确认日文版 Aspirations Index 有效性的调查。结果表明该量表具有合理的信度和结构效度。然后，在研究 2 中，我们对 42 名本科生（48 名本科生进行比较）实施了该计划并测试了其有效性。广义线性混合模型和混合设计方差分析的结果表明，干预成功地增加了参与者的内在愿望，但没有增加他们的外在愿望。此外，从定性数据来看，几乎所有参与者都报告说从干预计划中获益，并对他们的职业问题和内在抱负有了新的看法。总的来说，我们得出结论，拟议的教育干预可能是加强青年内在愿望的有效方法。
