This research intended to validate two brief scales of sensations seeking with Peruvian adolescents: the eight item scale (BSSS8; Hoyle, Stephenson, Palmgreen, Lorch, y Donohew, 2002) and the four item scale (BSSS4; Stephenson, Hoyle, Slater, y Palmgreen, 2003). Questionnaires were administered to 618 voluntary participants, with an average age of 13.6 years, from different levels of high school, state and private school in a district in the south of Lima. It analyzed the internal structure of both short versions using three models: a) unidimensional (M1), b) oblique or related dimensions (M2), and c) the bifactor model (M3). Results show that both instruments have a single dimension which best represents the variability of the items; a fact that can be explained both by the complexity of the concept and by the small number of items representing each factor, which is more noticeable in the BSSS4. Reliability is within levels found by previous studies: alpha: .745 = BSSS8 and BSSS4 =. 643; omega coefficient: .747 in BSSS8 and .651 in BSSS4. These are considered suitable for the type of instruments studied. Based on the correlation between the two instruments, it was found that there are satisfactory levels of equivalence between the BSSS8 and BSSS4. However, it is recommended that the BSSS4 is mainly used for research and for the purpose of describing populations.
八项目量表（BSSS8；Hoyle、Stephenson、Palmgreen、Lorch 和 Donohew，2002 年）和四项目量表（BSSS4；Stephenson、Hoyle、Slater 和 Palmgreen，2003 年）。问卷由来自利马南部一个地区不同高中、州立和私立学校的 618 名自愿参与者填写，平均年龄为 13.6 岁。该研究使用三种模型分析了两个简短版本的内部结构：a）单维模型（M1）、b）斜交或相关维度模型（M2）和 c）双因素模型（M3）。结果表明，两种工具都具有单一维度，最能代表项目的可变性；这一事实可以通过概念的复杂性和每个因素所代表的项目数量较少来解释，后者在 BSSS4 中更为明显。可靠性处于先前研究发现的水平：BSSS8 的 alpha 值为.745，BSSS4 的 alpha 值为.643；BSSS8 的 omega 系数为.747，BSSS4 的 omega 系数为.651。这些都被认为是适合所研究的工具类型。基于两个工具之间的相关性，发现 BSSS8 和 BSSS4 之间存在令人满意的等效水平。然而，建议主要使用 BSSS4 进行研究和描述人群。
