The author describes 4 patients in whom radically new symptoms appeared after intensive behavior therapy. He suggests that fresh symptoms are most likely to develop in a small minority of patients who are unable to learn more adaptive psychological defense mechanisms during or after behavior therapy and that psychoanalytic theory may help predict the nature of such symptoms.
作者描述了4例患者，他们在强化行为治疗后出现了全新的症状。他认为，在行为治疗期间或之后无法学会更具适应性心理防御机制的少数患者最有可能出现新症状，并且精神分析理论可能有助于预测此类症状的性质。
