The overall scientific goal is to investigate how society can reduce the vulnerability of people in family transitions through socially innovative actions within three social institutions (judiciary, economy and education). The resulting derivative scientific objective is to develop an experimental methodology (eg. Pre and post measurements, simulation studies, evaluation, etc.) to determine whether the proposed socially innovative actions actually reduce the aforementioned vulnerabilities '' and to apply this methodology in the field of family sciences, and this from a multidisciplinary perspective (psychologists, demographers, sociologists and lawyers).
