The Levels of Emotional Awareness Scale (LEAS) was developed to assess the emotional awareness construct, based on a cognitive-developmental perspective and influenced by the Piaget and Werner theories. It is composed of 20 emotion-evoking scenes and has been used in multiple researches related to emotion regulation, alexithymia and psychiatric disorders. It is a well-documented, valid and reliable measure. Due to the extent of LEAS, some investigators have been using one of the parallel forms (LEAS-A), which is a part of the complete version, nevertheless there is a gap of studies concerning LEAS-A psychometric qualities. In the absence of measures for assessing the organization of the emotional experience in Portuguese samples, we developed the Portuguese version of LEAS, characterizing reliability and validity indicators and the same for LEAS-A.
Three different studies were carried out with these versions, two with university students and another with a sample from the general population.
The Portuguese version showed high levels of reliability, superior to those found in other adaptation procedures. LEAS-A showed good reliability and indicators of discriminant and concurrent validities. The LEAS-A scores were independent from negative affect and related to the externally-oriented thinking involved in alexithymia.
The Portuguese LEAS and LEAS-A show very adequate qualities, which allow for their scientific use. Implications for clinical and research contexts are discussed.
情绪觉察水平量表（LEAS）是基于认知发展视角，并受皮亚杰和沃纳理论影响而开发的，用于评估情绪觉察结构。它由20个引发情绪的场景组成，已被用于多项与情绪调节、述情障碍和精神疾病相关的研究中。这是一种有充分文献记载、有效且可靠的测量工具。由于LEAS篇幅较长，一些研究者一直在使用其平行版本之一（LEAS - A），它是完整版本的一部分，然而关于LEAS - A心理测量学质量的研究存在空白。在缺乏评估葡萄牙语样本中情绪体验组织的测量工具的情况下，我们开发了LEAS的葡萄牙语版本，并对其可靠性和有效性指标以及LEAS - A的指标进行了描述。
使用这些版本进行了三项不同的研究，两项针对大学生，另一项针对普通人群样本。
葡萄牙语版本显示出较高的可靠性，优于其他改编程序中的可靠性。LEAS - A显示出良好的可靠性以及区分效度和同时效度指标。LEAS - A得分与消极情绪无关，且与述情障碍中涉及的外向性思维相关。
葡萄牙语版的LEAS和LEAS - A表现出非常合适的质量，使其能够科学应用。文中讨论了其在临床和研究背景下的意义。
