Abstract: | This study investigated social television viewing behavior by introducing the social engagement construct and validating its measurement scale. A total of 655 social media users in 2 online consumer panels were sampled to complete the 3-stage research strategy. Through conceptualization and operationalization of social engagement, this study identified 4 underlying dimensions in social engagement, i.e., vertical involvement, diagonal interaction, horizontal intimacy, and horizontal influence. These 4 dimensions represent a continuum in which audiences’ social engagement behaviors range from a lower level (vertical involvement) to a higher level (horizontal influence). The theoretical and practical implications of the social engagement construct were also discussed. |
