Association Splitting (AS) is a novel cognitive technique, which has shown some promise for the reduction of obsessive thoughts in patients with obsessive-compulsive disorder (OCD). Its effect on unwanted intrusive thoughts (UITs) in the general population is yet unknown.
Our experimental study tested the effect of AS in 49 participants who reported UITs as a regular problem. Participants were randomly allocated either to an AS versus waitlist control (WL) condition. The White Bear Suppression Inventory (WBSI) was used for measuring changes over time.
Significant group differences were found across time. Relative to WL, AS exerted a positive effect on the reduction of UITs yielding a large effect size. According to self-report AS exerted a positive effect 6 days after the participants had initiated the exercises. All subjects in the AS condition judged the technique as effective.
Results suggest that AS could be a suitable intervention to help people with a potential vulnerability to a clinical problem to control their UITs.
联想分离（AS）是一种新颖的认知技术，已显示出在减少强迫症（OCD）患者的强迫思维方面具有一定的潜力。但其对普通人群中不需要的侵入性思维（UIT）的影响尚不清楚。
我们的实验研究测试了 AS 对 49 名报告 UIT 为常见问题的参与者的影响。参与者被随机分配到 AS 组或等待名单对照组（WL）。采用白熊抑制量表（WBSI）来衡量随时间的变化。
发现组间随时间存在显著差异。与 WL 相比，AS 对 UIT 的减少有积极影响，产生了较大的效果量。根据自我报告，AS 在参与者开始练习 6 天后对 UIT 产生了积极影响。AS 组的所有受试者均认为该技术有效。
结果表明，AS 可能是一种合适的干预措施，可以帮助那些有临床问题潜在易感性的人控制他们的 UIT。
