Did Dr. Gottman (or any other researcher) replicate the findings in the research studies?
The divorce and happiness change predictions are probably among the most replicated studies in the family research field. For example, Rand Conger’s group (including Ron Simons) at Iowa State University replicated some of Gottman’s divorce prediction studies. Julia Babcock at the University of Houston also replicated some of Gottman and Jacobson’s work on domestic violence.
