This chapter explores many kinds of resistance to psychotherapy and to self-help therapy and describes how one, as a therapist, can effectively deal with them. Obviously, however, it will favor Rational Emotive Behavior Therapy (REBT) that started in 1955 and that has developed into Cognitive Behavior Therapy (CBT) in the 1960s and 1970s. Therefore, for REBT and CBT to be effective, one had better convince clients of the importance of their beliefs and show them that it is quite possible to change them and thereby improve their disturbing Consequences (C’s). The chapter emphases on a number of cognitive, emotive, and behavioral techniques, and is therefore similar to what Arnold Lazarus calls multimodal therapy. REBT, more than the other Cognitive Behavior Therapies, particularly differentiates healthy negative feelings, such as concern, sorrow, regret, frustration, and annoyance from unhealthy or destructive feelings, such as panic, depression, and rage.
