This article introduces and develops a comprehensive scale named Octomodal Mental Imagery (OMI) to measure various aspects of imagination and prospection. OMI is developed and validated by conducting three rigorous studies and six data collections. In the first study, using the phenomenology approach, a detailed internal experience of the imagination process was carefully recorded. In the second study, the potential manifest variables to measure imagination/prospection were developed and a general configuration of the questionnaire was determined. In the third study, through three data collections, two versions of long (original) and short OMI were thoroughly screened, refined, and validated. Furthermore, from the measurement and structural perspectives, the conceptualization of imagination was compared to prospection. Our results substantiate OMI as a reliable and valid scale to be used in and out of hedonic consumption contexts.

本文介绍并开发了一个名为 Octomodal Mental Imagery (OMI) 的综合量表来衡量想象力和前景的各个方面。OMI 是通过进行三项严格的研究和六项数据收集来开发和验证的。在第一项研究中，使用现象学方法，仔细记录了想象过程的详细内部体验。在第二项研究中，开发了衡量想象力/前景的潜在显性变量，并确定了问卷的一般配置。在第三项研究中，通过三个数据收集，对长（原始）和短 OMI 的两个版本进行了彻底筛选、提炼和验证。此外，从测量和结构的角度，将想象的概念化与展望进行了比较。
