Participants were assigned into a treatment group (i.e., divorce recovery workshop) based on a first-come, first-serve basis. Specifically, the first 50 people who signed up were given the divorce recovery workshop. The next 50 people who signed up were put into a comparison group (i.e., they did not get the divorce recovery workshop class). Both groups were given a pretest and posttest.
