I am looking for a collaborator familiar with Solomon's four-group analysis to do experiments and write articles together, focusing on analyzing the social media video reception.

The Solomon four-group design is rarely used. You are probably familiar with it through the early work of Campbell and Stanley, but the conclusion over time is that are very few cases where it is necessary to eliminate real-world threats to validity. Instead, there has been widespread adoption of the pre-post design with control group as adequate in nearly all cases where one might consider the Solomon four-group design instead.
