The collaboration between humans and collaborative intelligence systems such as voice assistants (VAs) is increasingly relevant in both professional and everyday contexts. However, valid measures to capture users’ behavioral contributions to this collaboration are lacking.
The article introduces the concept of collaboration intensity which refers to the extent to which an individual is engaging effectively and pro-
ductively with a collaborative intelligence system (e.g., voice assistants) in pursuit of a joint task or goal and develops the Collaboration Intensity Scale (30 items) incl. a short version (12 items).
Based on item response theory, the new Collaboration Intensity Scale offers researchers and practitioners a validated tool to assess and enhance human–VA collaboration by identifying behavioral patterns and informing the design of more effective VA features.
