I think that not only a therapist but also a coach should pay attention to "transference" between a client and coach in a session, so I capsulized the concept below.
This psychological phenomenon between a client and therapist is one of the key concepts in a therapeutic setting. Freud categorized this concept into the following three ideas.
1 The positive transference, in which the patient’s feelings for the therapist are primarily affection and trust.
2 The negative transference, consisting primarily of hostility and suspicion.
3 The un-neutralized erotic transference, in which the patient experiences insistent desire for sexual intimacy with the analyst. (Kahn, 2002, pp.184-185)
About the positive transference, Freud regarded it as an unobjectionable phenomenon and insisted that it enabled a therapist to provide a client with a sense of trust or safety which built a preferable relationship between the client and therapist. On the other hand, Freud raised an alert over the negative transference. He argued that a therapist must intervene in and remove it if the transference comes up in the session. Otherwise the therapy session will not work for a client. Likewise the negative transference, Freud warned that the erotic transference had a negative impact on the therapy session. Although it is sometimes recognized as a kind of the positive transference, Freud explained that “if those feelings persisted in spite of the analyst’s best effort to convert them to analyzable material, there was nothing to do but refer the patient to another therapist” (Kahn, 2002, p.186). Thus, a therapist should have a competency to discern the type of transference.
