A consumption dimension-based approach to product perceived newness: concept, measurement, and validation
提出基于消费维度的产品感知新颖性概念，开发并验证了一个四维度21题项的量表，用于测量消费者认为产品在功能、情感、社会、认知维度上的新颖程度。
This research conceptualizes Consumption Dimension-based Product Perceived Newness (CDPPN) as a consumer’s perception that a product is novel on the dimensions of consumption that are important to them and develops a scale reflecting this conceptualization. Prior research characterizes product perceived newness as a unidimensional attribute reflecting the extent a consumer perceives a product as new and unique. This approach is problematic because it fails to capture the complexity of consumers’ perceptions of newness, which this study suggests depends on the attributes consumers deem most important. This research presents a quadripartite dimensional framework, functional, emotional, social, and epistemic, for understanding CDPPN. Seven studies support and validate this framework. The proposed 21-item four-dimensional CDPPN scale proves to be reliable and internally valid in two different cultural contexts. Criterion validity is established by estimating its (a) predictors: actual level of newness (incremental versus radical), category experience, consumer expertise, and consumer innovativeness; and (b) outcomes: attitude, behavioral intentions, and market success. The CDPPN scale can serve as a tool for future research on new product development by capturing the newness aspects most important to consumers.
