Thirty women about to undergo hysterectomy were sequentially assigned to three equal groups. The first two groups were taught methods of cognitive control over anxiety, either through a detailed booklet (group 1) or orally (group 2). The third group served as attention-placebo controls. The two experimental groups reported less pain and distress than the control group, who spent longer in hospital and were more prone to post-operative vomiting. The booklet proved neither more nor less beneficial than oral teaching on the criteria adopted, and is therefore seen as more cost effective.
30名即将接受子宫切除术的女性被依次分为三组，每组人数相等。前两组通过详细的手册（第1组）或口头方式（第2组）学习对焦虑进行认知控制的方法。第三组作为注意力安慰剂对照组。两个实验组报告的疼痛和痛苦程度低于对照组，对照组住院时间更长，术后更易出现呕吐。就所采用的标准而言，手册教学与口头教学的效果并无优劣之分，因此手册教学被视为更具成本效益。
