In the process of psychotherapy, one most commonly comes across “resistance”. Resistance is the counterforce against the efforts of treatment. Freud(1912) called it ‘a compromise between the efforts to cure and its opposing force.’ Resistance occurs in every psychotherapeutic process. Psychoanalysis, or dynamic psycho theory, is distinguished from other psychotherapies by using transference and resistance as active therapeutic tools. Resistance can sometimes be easily noticed when, for example, one assumes silence; however, on other incidences, such as evasion of certain themes or unconscious conflicts, resistance is difficult to perceive. Although resistance can be termed as an obstacle of treatment, it is a turning-point to unravel the deadlock of a treatment. It can also be a way to unearth the repository of the patient’s unconscious. Consequently, fully understanding and utilizing the concept of resistance will allow a more effective treatment in not only dynamic therapy but also supportive therapy. This study includes the definition of resistance in dynamic psychotherapy and a method to employ it.
