摘要

Background

In the treatment of obsessive–compulsive disorder (OCD), imagery rescripting (ImRs) is considered promising. However, there is a paucity of randomized-controlled trials (RCTs) with active control groups in this context.

Methods

We developed an audio imagery, which we refer to as the spit-face scenario, to induce disgust without any sexual content. In an online RCT, we then investigated disgust (SDQ-13, visual analogue scale (VAS)) and anxiety (STAI-SKD, VAS) in participants reporting at least mild OC symptoms after one of three manipulations, ImRs (n = 34), imagery focus (n = 25) or distraction (n = 34).

Results

The spit-face scenario significantly induced disgust, e.g., comparable with watching a disgusting film, and over 70% of the participants were able to vividly visualize and follow the scenario effectively. Although ImRs and distraction reduced disgust, it did not decline following imagery focus (e.g., SDQ-13, F-HF = 86.600 (1.756), p < .001, f = 0.98). Whereas disgust performed similarly in the SDQ-13 and the VAS, there were slightly different patterns in the anxiety measures.

Conclusions

Although the results might suggest an effect of a one-session online ImRs audio manipulation, the question remained if ImRs had a differential effect beyond distraction. The results thus underline the need to conduct further research on the active elements of ImRs.
