The concept of countertransference as a robust cornerstone of psychoanalytic work has gained momentum over the last five decades. It is a prime example of elastic concepts covering the range from microprocesses to global clinical phenomena. Empirical research on the treatment process has for a long time – and for good reasons – avoided even trying to measure countertransference. We report here on various efforts for approaching a methodology for measuring it. The paper organizes the various approaches in terms of stages of research.
