Modelling and Measuring Group Cohesiveness with Consonance: Intertwining the Sociometric Test with the Picture Apperception Value Test

The purpose of this research is to model, measure and explain group cohesiveness through consonance. For this aim, we propose a holistic framework that combines the sociometric test with the novel Picture Apperception Value Test for defining group cohesiveness by assessing interpersonal attraction of group members through categorical values. The research approach is quantitative, classified both as inferential and quasi‐experimental. Findings indicate that the holistic framework serves as an effective model for measuring group cohesiveness, much more that it can be the sociometric test alone. Research originality and value derives from the fact of combining one existing and consolidated tool like the sociometric test, with an innovative tool like Picture Apperception Value Test for the measurement of group cohesiveness. Regarding practical implications, through the first instrument it is possible to create groups; with the second, it is possible to measure in a new way the interpersonal attraction based on individual's value system.
