摘要

背景：两项实验（E1 和 E2；样本数分别为 44 和 52）研究了关于牙科手术的积极信息（PI）和中性信息（NI）的效果，以及治疗小组（公开管理）或治疗小组不知情的情况下（隐藏管理）提供的信息是否会影响疼痛：采用混合设计，将接受臼齿钻孔治疗的患者随机分为 NI 组和 PI 组。在治疗前、治疗中和治疗后，患者报告其疼痛和压力水平。在 E1 组中，由治疗小组提供信息。在 E2 中，由一名未参与治疗的助手提供信息：结果：在 E1 中，PI 组的疼痛比 NI 组减轻了 50%，压力对疼痛的影响也有所减轻。这些影响在 E2 中消失了。据牙医报告，在 E1 阶段，PI 组的牙医表现出了积极的非语言行为（如微笑和更长时间的眼神交流），但在 E2 阶段则没有：讨论：正面信息只有在公开发布时才会减轻疼痛。对治疗小组隐藏的正面信息没有效果。由于两个实验中的信息相似，在 E1 中，信息以外的因素很可能减轻了 PI 组的疼痛：由治疗小组提供积极信息可能会产生行为线索，从而产生安慰剂效应。

Effects of open and hidden administration of treatment-related information; a multi-experiment study.

Background: Two experiments (E1 and E2; N = 44 and N = 52, respectively) investigated the effect of positive (PI) and neutral information (NI) about a dental procedure, and if the delivery of the information by the treatment team (open administration) or unbeknownst to the treatment team (hidden administration), affected pain.

Methods: Using a mixed design, patients undergoing drilling in a molar were randomized to the NI or PI groups. Before, during, and after treatment, patients reported their pain and stress levels. In E1 the treatment team delivered the information. In E2, an assistant not engaged in the treatment delivered the information.

Results: In the PI group in E1, pain was reduced by 50 % compared to the NI group, and the effects of stress on pain were mitigated. These effects were abolished in E2. The dentist reported having displayed positive nonverbal behaviours (e.g. smiling and longer eye contact) in the PI group in E1, but not in E2.

Discussion: Positive information reduced pain only when administrated openly. There was no effect of positive information administrated hidden from the treatment team. As information was similar in both experiments, factors other than the information most likely reduced pain in the PI group in E1.

Conclusion: Delivering positive information by the treatment team may generate behavioural cues which generate placebo effects.

The contents include work on psychological aspects of physical illness, treatment processes and recovery; psychosocial factors in the aetiology of physical illnesses; health attitudes and behaviour, including prevention; the individual-health care system interface particularly communication and psychologically-based interventions. The journal publishes original research, and accepts not only papers describing rigorous empirical work, including meta-analyses, but also those outlining new psychological approaches and interventions in health-related fields.
