The year is 1995. Kansas State University doctoral student Lee Johnson sits at his carrell desk, contemplating the possibilities for improving marriages and families as a developing clinician and a researcher. He wonders what it would look like to have access to data from not only his own practice but also from a greater network of therapists. If he could do this, he could better understand clinical change in relational therapy. Flash forward to 2020, when Dr. Johnson’s own doctoral and master’s students are using the Practice Research Network to collect data from each of their clients, contribute to a global dataset, and inform their treatment.
