Cognitive, Affective and Conative Domains of Sustainable Consumption: Scale Development and Validation Using Confirmatory Composite Analysis

This study aims to conceptualise, develop, purify and validate a multiple-item scale to measure a sustainable consumption (SC) construct from the perspective of developing countries, particularly Malaysia. Interview, a focus group and survey methods were used to collect qualitative and quantitative data from respondents. Content Analysis, Exploratory Factor Analysis (EFA) and Confirmatory Composite Analysis (CCA) using Partial Least Square (PLS) were used to explore and predict the data. The EFA output generated three dimensions with 21 items. The dimensions are cognitive SC, affective SC and a conative SC that reflects the notion of sustainable consumption. The result of the CCA confirmed the EFA result. Based on the reliability and validity check results, it is apparent that the scale demonstrates good psychometric properties. This is a pioneer study that developed a new scale to measure sustainable consumption behaviour in a non-Western context. In addition, this study conceptualised sustainable consumption behaviour as a multi-dimensional attitudinal construct determined by the cognitive, affective and conative aspects of the mind.
