概要	LODGSERV is a 26-item index developed by Knutson, Stevens, Wullaert, Patton, and Yokoyama in 1990 to measure consumers' expectations of service quality in the hotel experience. Building directly on the SERVQUAL framework, it organizes lodging expectations into the five generic service-quality dimensions — tangibles, reliability, responsiveness, assurance, and empathy — and was reported with a high internal-consistency reliability of 0.92. LODGSERV was one of the first industry-specific adaptations of SERVQUAL and served as the methodological forerunner to the restaurant-focused DINESERV from the same research group. It gives hoteliers a validated way to capture what guests expect from a stay and to structure those expectations for comparison with delivered performance.	DINESERV is a 29-item instrument developed by Stevens, Knutson, and Patton in 1995 to measure perceived service quality in restaurants. It adapts the five generic SERVQUAL dimensions of Parasuraman, Zeithaml, and Berry — tangibles, reliability, responsiveness, assurance, and empathy — to the specific realities of foodservice, where the meal experience blends physical surroundings, the dependability of order delivery, staff attentiveness, the competence and trustworthiness of servers, and individualized care. By administering DINESERV to diners, an operator obtains a structured reading of how customers perceive quality across these dimensions, can locate where the experience falls short, and can prioritize improvements. The scale has become one of the most widely used purpose-built measures of restaurant service quality.
