In response to repeated calls for process research on couple and family the
rapy, three different process research methodologies - grounded theory, cha
nge events analysis, and experimental manipulation - are presented and eval
uated. A process research conceptual framework outlining some of the import
ant issues in process research is presented. To illustrate each methodology
, three completed process studies are briefly described, and a sample of re
sults is provided. The strengths and weaknesses of each methodology are dis
cussed, along with their role in generating and testing clinically relevant
change theories, It is argues that each of these methodologies can provide
researcher with important tools for unraveling the processes of change in
couple and family therapy and should be used more frequently.
