概要	The Consumer Involvement Scale (CIS), developed by Zaichkowsky (1985), measures the degree to which a consumer feels personally invested in a product, brand, or purchase decision. Originally a 20-item instrument operationalizing the concept of 'personal relevance,' the CIS was refined to 10 items in 1994 (Revised Personal Involvement Inventory, PII), maintaining measurement of consumer involvement across multiple semantic dimensions. Involvement captures both the personal importance of a product category and the perceived risk of making a poor choice. The scale is fundamental in consumer behavior research for understanding motivation, information processing, and purchase decision intensity.	The Brand Equity Scale (BES) measures customer-based brand equity through perceived quality, brand loyalty, brand associations, and brand awareness. Developed by Yoo, Donthu, and Lee (2000), building on Aaker's foundational brand equity framework (1991), the BES operationalizes brand equity as the differential effect of brand knowledge on consumer response to marketing activities. The scale enables organizations to quantify the value customers attach to their brand and diagnose which equity dimensions require strategic investment.
