Incompleteness (INC) and Harm Avoidance (HA) are known core dimensions of obsessive-compulsive disorder (OCD). Emotional processing and inhibitory learning (IL) have both been proposed as viable mechanisms of exposure for the alleviation of HA, yet the relationship with INC remains unclear. This study evaluated differential manipulation responses to induced INC. The authors specifically tested whether targeting the key component of IL, expectancy violation generated by the discrepancy between an articulated prediction and the actual exposure experience, would lead to improved outcomes. A sample of undergraduates (N = 68) completed a series of behavioral tasks to induce INC, followed by manipulations (exposure with or without articulated predictions) to reduce INC reactions. Results show that modest changes were observed following reduction manipulations following INC induction. Furthermore, heightened HA predicted the changes of induced sensations. Mediation tests showed that articulation of predicted sensations mediated pre- to postreduction ratings. Clinical and research implications are discussed.

诱导和操纵不完整感

不完整（INC）和避免伤害（HA）是强迫症（OCD）的已知核心维度。情绪处理和抑制性学习（IL）均被认为是缓解HA的可行暴露机制，但与INC的关系仍不清楚。这项研究评估了对诱导的INC的不同操作响应。作者专门测试了针对IL的关键成分，由明确的预测与实际接触经验之间的差异所产生的预期违背，是否会导致改善结果。样本（N = 68）的大学生完成了一系列诱导INC的行为任务，然后进行了一些操作（有无明确预测的接触）以减少INC反应。结果显示在INC诱导后的还原操作后观察到适度的变化。此外，HA的升高预示了诱导感觉的变化。调解测试表明，预期感觉的表达介导了还原前后的等级。讨论了临床和研究意义。
