Abstract: Empirical research on the treatment processhas long time - for good reasons - avoided toeven try to measure countertransference,although this dimension of thepsychoanalytic work has gained inmomentum over the last decades. Our paper reports on various efforts of howto approach such a methodology formeasuring such an elusive concept. Thedistinction between habitual patterns ofcountertransference and situational affectivereactions seems most likely a helpful way toapproach the topic. Recent empirical researchand measures on countertransference will bepresented and discussed.
