Condom use is the most effective preventive behavior against HIV transmission, and its inadequate use is a public health problem that occurs mostly among youth and young adults. Although there are scales that measure condom use, those that exist correspond to English-speaking developments or do not have psychometric evidence to support them, so it is possible that the available adaptations of instruments do not adequately reflect the phenomenon in the Chilean population. Thus, the study aims to develop a scale to assess attitudes toward condom use in Chilean youth and young adults. Initially, a sample of students between 18 and 39 years ( = 520) was used for debugging the instrument. Then, a second sample was taken from the general population aged 18 to 40 ( = 992) to confirm the factor structure of the proposed model. The final scale has 10 items and 3 attitudinal dimensions (affective, cognitive, and behavioral). The results show that the identified structure provides adequate levels (ω > 0.7) or at least sufficient of reliability (ω > 0.6) and presents evidence of validity, based on the internal structure of the test, through ESEM (CFI = 0.993; TLI = 0.984; RMSEA = 0.056). In addition, evidence of validity was obtained based on the relationship with other variables and strong invariance between the scores of men and women. It is concluded that the scale developed has adequate psychometric properties to assess, in brief form, condom use attitudes in equal samples for research and screening purposes.
使用避孕套是预防艾滋病毒传播最有效的预防行为，而避孕套使用不足是一个主要发生在青年和年轻成年人中的公共卫生问题。尽管有测量避孕套使用情况的量表，但现有的量表要么是基于英语国家的研究开发的，要么没有心理测量学证据支持，因此现有的工具改编版可能无法充分反映智利人群中的这一现象。因此，本研究旨在开发一个量表，以评估智利青年和年轻成年人对避孕套使用的态度。最初，使用了18至39岁的学生样本（n = 520）来调试该工具。然后，从18至40岁的普通人群中抽取了第二个样本（n = 992），以确认所提出模型的因子结构。最终量表有10个项目和3个态度维度（情感、认知和行为）。结果表明，所确定的结构提供了足够的水平（ω > 0.7）或至少足够的信度（ω > 0.6），并通过ESEM（CFI = 0.993；TLI = 0.984；RMSEA = 0.056）基于测试的内部结构呈现了效度证据。此外，基于与其他变量的关系以及男性和女性得分之间的强不变性获得了效度证据。结论是，所开发的量表具有足够的心理测量学特性，能够以简短形式评估研究和平等样本筛查目的下的避孕套使用态度。
