In a 2 x 2 factorial design massed vs spaced and therapist vs self-controlled exposure were compared with obsessive-compulsive patients. Intersession interval was varied keeping constant the length of exposure time and number of exposure sessions. Treatment in all conditions was home based. Treatment led to highly statistical and significant improvements on all measures. Massed exposure was as effective as spaced exposure; self-controlled exposure proved to be as effective as therapist-controlled exposure.
在一项2×2析因设计中,对强迫症患者比较了集中暴露与间隔暴露以及治疗师控制暴露与自我控制暴露。在保持暴露时间长度和暴露疗程数量不变的情况下,改变疗程间隔时间。所有条件下的治疗均在家中进行。治疗在所有测量指标上都带来了高度统计学显著的改善。集中暴露与间隔暴露效果相同;自我控制暴露被证明与治疗师控制暴露效果相同。
