Consumers' engagement with social media activation campaigns: Construct conceptualization and scale development

This study conceptualizes the consumers' engagement with social media activation campaigns, which are important tools in improving the interactions between brands and consumers. We offer a comprehensive definition of this construct and discuss the nature and dimensionality of it. Further, this paper reports the development and validation of a 12‐item scale for measuring the aforementioned construct. This scale development process comprises four studies. Study 1 begins by generating a pool of items and then employs both a panel of experts and some Instagram users to examine the content validity of the items. To validate the scale, this paper carries out several online surveys in subsequent studies. Study 2 uses exploratory and confirmatory factor analysis (CFA) to remove the problematic items and evaluate the dimensionality of the construct. In Study 3, we conduct iterative CFAs to purify the scale and reassess the psychometric properties of the scale. Study 4 uses structural equation modeling to test the nomological validity. Our analyses reveal that consumers' engagement with social media activation campaigns is a second‐order construct encompassing three first‐order dimensions (cognitive, emotional, and behavioral engagement). The results also support the reliability, content validity, convergent validity, discriminant validity, known group validity, and nomological validity of the engagement scale.
