Safety behaviors, defined as engagement in avoidance within safe environments, are a key symptom of obsessive-compulsive and related disorders. They may interfere with daily functioning and as such their emission should be reduced. The purpose of the current study is to investigate the effects of the non-contingent presentation of safety signals (cues produced by safety behaviors) on reducing safety behaviors in participants self-reporting low and high OCD profiles.
In total, 32 participants were asked to play a game to gain points and avoid their loss. After having developed avoidance behavior, evidenced by maintaining all of their earned points, they were exposed to safe environments where no point loss was programmed. In Test 1, safety cues (blue bar) were produced contingent on performing safety behaviors. In Test 2, safety cues were presented continuously without any response requirement.
Findings demonstrated that high OCD group displayed higher rates of safety behaviors than low OCD group. However, exposure to the non-contingent presentation of safety signals eliminated their emission in both groups.
Future studies need to evaluate the effects of different non-contingent schedules on the suppression of safety behaviors.
These findings contribute to the literature by demonstrating that non-contingent introduction of safety signals eliminated safety behaviors completely, even in high OCD participants, who performed safety behavior at higher rates. Such a treatment protocol may ameliorate exposure therapy in which response prevention constitutes a key element and is generally associated with increased drop-out rates.
安全行为被定义为在安全环境中采取回避行为,是强迫症及相关障碍的关键症状。它们可能会干扰日常功能,因此应减少其出现频率。本研究旨在调查非条件性呈现安全信号(由安全行为产生的提示)对减少自我报告有低强迫症症状和高强迫症症状的参与者的安全行为的影响。
总共32名参与者被要求玩一个游戏来获取分数并避免分数损失。在形成回避行为后(通过保留所有已获得的分数来证明),他们被置于不会出现分数损失的安全环境中。在测试1中,安全提示(蓝色条)根据安全行为的执行情况而产生。在测试2中,安全提示持续呈现,无需任何回应要求。
研究结果表明,高强迫症组的安全行为发生率高于低强迫症组。然而,非条件性呈现安全信号使两组的安全行为都不再出现。
未来的研究需要评估不同非条件性安排对抑制安全行为的影响。
这些研究结果为文献做出了贡献,表明非条件性引入安全信号能完全消除安全行为,即使是在高强迫症参与者中,他们的安全行为发生率更高。这样的治疗方案可能会改善暴露疗法,在暴露疗法中,反应阻止是一个关键要素,且通常与较高的退出率相关。
