Heterosexual attitudes toward individuals with other sexual orientations and identities, such as lesbian, gay, bisexual, transgender, intersex, asexual, etc. (LGBTQIA+), have been conceptualized as multidimensional and wide-ranging. With the objective of measuring these attitudes, Worthington and colleagues developed the Lesbian, Gay, and Bisexual Knowledge and Attitudes Scale for Heterosexuals (LGB-KASH). In this article, 540 college students were administered the LGB-KASH; these data were examined for their psychometric properties of the instrument using a sequential approach. The first step included descriptive analysis, including internal consistency measures and association rules, followed by the evaluation of dimension structure with factor analysis (confirmatory/exploratory), and, finally, item analysis using non-parametric (Mokken scale analysis) and parametric approaches (item response theory). Specific to the LGB-KASH factor structure, the current structure was not supported by these data; however, alternative subsets of items that could be used to revise the original instrument to obtain a more psychometrically sound measure are suggested.
异性恋者对具有其他性取向和身份的个体，如女同性恋者、男同性恋者、双性恋者、跨性别者、双性人、无性恋者等（LGBTQIA+）的态度，已被概念化为多维度且广泛的。为了测量这些态度，沃辛顿及其同事开发了异性恋者的女同性恋、男同性恋和双性恋知识与态度量表（LGB-KASH）。在本文中，对540名大学生进行了LGB-KASH测试；采用序贯方法对这些数据进行了该量表心理测量学特性的检验。第一步包括描述性分析，包括内部一致性测量和关联规则，接着通过因子分析（验证性/探索性）评估维度结构，最后使用非参数方法（莫肯量表分析）和参数方法（项目反应理论）进行项目分析。具体针对LGB-KASH的因子结构，这些数据并不支持当前结构；然而，建议了可用于修订原始量表以获得更具心理测量学可靠性的测量方法的替代项目子集。
