The PSI-Process Scales. A new measure to assess the intensity and breadth of parasocial processes

<jats:title>Abstract</jats:title> <jats:p>Research on parasocial interactions (PSI) and parasocial relationships (PSR) refers back to a tradition of 50 years. However, research on both phenomena still suffers from overlapping definitions and resulting measurements that do not distinguish between PSI and PSR. The present study presents a post-exposure measurement tool (the PSI-Process Scales) that aims to measure PSI instead of PSR. It is derived from a theoretical model that specifically focuses on PSI. Psychometric analyses indicate the tool's high usability. It is capable of displaying both the intensity and the dimensionality of PSI. It can be applied to measure both positive and negative PSI across all TV formats, without changing the item wording. In sum, the PSI-Process-Scales may offer a valuable alternative for researchers in the field, specifically if they want to assess parasocial processes that take place throughout TV exposure.</jats:p>
