Twenty subjects were randomly allocated to receive either imaginal desensitization (ID) or covert sensitization (CS) to reduce compulsive anomalous sexual behaviours. It was predicted from a behavioural completion model of compulsive urges, that patients' response to ID would be at least as good as their response to CS and would correlate with reduction in their general levels of tension following treatment. These predictions were supported. Correlations between patients' expectancies of treatment success and their response were of moderate strength for expectancy measures taken following the first session of both treatments, but much stronger for expectancy measures following the last session of ID. It was suggested that patients experienced a specific response during the further sessions of ID, which enabled them to improve their prediction of response. As aversive therapies remain the standard behavioural therapy for sexual paraphilias, the finding of the present study that imaginal desensitization without traumatic imagery or aversive physical stimuli is at least as effective would seem to require urgent replication, if only on ethical grounds.
20名受试者被随机分配接受意象脱敏疗法（ID）或隐蔽致敏疗法（CS），以减少强迫性异常性行为。根据强迫冲动的行为完成模型预测，患者对ID的反应至少与对CS的反应一样好，并且与治疗后总体紧张水平的降低相关。这些预测得到了支持。在两种治疗的第一疗程后进行的预期测量中，患者对治疗成功的预期与他们的反应之间的相关性为中等强度，但在ID的最后疗程后的预期测量中相关性更强。有人认为，患者在ID的后续疗程中经历了特定的反应，这使他们能够改进对反应的预测。由于厌恶疗法仍然是性偏好障碍的标准行为疗法，本研究发现无创伤性意象或厌恶身体刺激的意象脱敏疗法至少同样有效，这一发现似乎需要紧急重复验证，哪怕只是基于伦理原因。
