Intrinsic and extrinsic types of motivation have been widely studied, and their importance on both developmental and educational practices has led to the development of assessment tools. The Aspiration Index scale (AI; Grouzet et al., 2005), which was developed to measure people`s life aspirations, was translated and validated into Portuguese. A sample of 1,359 adolescents, age ranged from 12 to 18 years-old, participated in the present study. Results showed that a factor structure with the eleven subscales of the AI does not fit the data. However we gathered support for a three-factor structure that organized the items in terms of whether aspirations are intrinsically, extrinsically or self-transcendent oriented. Internal consistency and temporal stability yielded good results. The predictive and criterion validities were demonstrated by significant associations with theoretically supported measures of satisfaction with life and father and mother attachment. The multi-group confirmatory factor analysis showed that this structure was invariant across gender. These results suggest that the AI is a reliable measure to assess different types of life aspirations and can be used in future research with adolescents in Portugal.

验证葡萄牙语版本的青少年渴望指数 (AI)

内在和外在类型的动机已被广泛研究，它们对发展和教育实践的重要性导致了评估工具的发展。为衡量人们的生活愿望而开发的愿望指数量表（AI；Grouzet 等人，2005 年）被翻译并验证为葡萄牙语。1,359 名年龄在 12 至 18 岁之间的青少年样本参与了本研究。结果表明，具有 AI 的 11 个子量表的因子结构不适合数据。然而，我们收集了对三因素结构的支持，该结构根据愿望是内在的、外在的还是以自我超越为导向来组织项目。内部一致性和时间稳定性产生了良好的结果。预测效度和标准效度通过与理论上支持的生活满意度和父母依恋测量显着相关来证明。多组验证性因素分析表明，这种结构在不同性别之间是不变的。这些结果表明，人工智能是评估不同类型生活愿望的可靠措施，可用于葡萄牙青少年的未来研究。
