It has been proposed that the judicious use of safety behaviour can facilitate improvements in the acceptability of cognitive behaviour therapy (CBT). It was decided to explore the possibility of facilitating CBT by introducing a form of safety behaviour. We sought to assess the degree to which Exposure plus Safety Behaviour (E + SB) is an effective intervention for contamination fears.
A comparison was made between the effects of a control condition (Exposure and Response Prevention; ERP) and an experimental condition (Exposure plus Safety Behaviour; E + SB) in which each exposure to a contaminant was followed by the use of a hygienic wipe in a sample of (n = 80) undergraduate students. In session one, each participant touched a confirmed contaminant 20 times. After each exposure participants were asked to report their feelings of contamination, fear, disgust, and danger. In the second session, two weeks later, the same procedure was carried out for a further 16 trials.
The ERP and the E + SB conditions both produced large, significant and stable reductions in contamination. Significant reductions in fear, danger and disgust were also reported in both conditions.
The treatment was provided to an analogue sample and over two sessions.
The use of hygienic wipes, the safety behaviour used in this experiment, did not preclude significant reductions in contamination, disgust, fear and danger. If it is replicated and extended over a longer time-frame, this finding may enable practitioners to enhance the acceptability of cognitive behavioural treatments and boost their effectiveness.
合理使用安全行为可以促进认知行为疗法（CBT）的可接受性的提高。因此，有人提出通过引入安全行为的形式来促进 CBT。我们试图评估暴露加安全行为（E+SB）在减轻污染恐惧方面的有效性。
我们比较了控制条件（暴露和反应预防；ERP）和实验条件（暴露加安全行为；E+SB）的效果，在实验中，在对污染物进行每次暴露后，在 80 名本科生样本中使用了卫生擦拭物。在第一节课中，每个参与者接触确认的污染物 20 次。每次暴露后，参与者被要求报告他们的污染感、恐惧、厌恶和危险感。两周后，在第二节课中，对另外 16 次试验进行了相同的程序。
ERP 和 E+SB 条件都产生了大量、显著和稳定的污染减少。在两种条件下，恐惧、危险和厌恶感也显著降低。
治疗是提供给模拟样本，并在两个疗程中进行。
在这个实验中使用的卫生擦拭物，即安全行为，并没有阻止污染、厌恶、恐惧和危险的显著减少。如果经过复制和在更长的时间框架内扩展，这一发现可能使从业者能够提高认知行为治疗的可接受性并提高其有效性。
