A quasi-experimental study was conducted to examine the effects of information about an impending threatening event (barium enema) on subjects' expectations and the intensity of their emotional response to the event. Twenty subjects were assigned to one of two information conditions: sensation of procedure. Prior to receiving any information, all subjects completed a preinformation sensation inventory and the trait portion of the State-Trait Anxiety Inventory (STAI). A taped message of either sensation or procedural information was heard, followed by completion of the post-information sensation inventory. After the barium enema, all subjects completed the post-procedure sensation inventory and the state portion of the STAI. In neither the expected sensations (expectations) reported prior to hearing information or the responses provided after the procedure (actual experiences) were there significant differences between the two groups. However, after hearing the information, significant differences in reported expected sensations were found. Subjects receiving sensation information reported significantly less anxiety and expectations more congruent with their actual experiences than did subjects receiving procedural information.
进行了一项准实验研究，以检验关于即将发生的威胁性事件（钡灌肠）的信息对受试者的期望以及他们对该事件的情绪反应强度的影响。20名受试者被分配到两种信息条件之一：操作感受。在接收任何信息之前，所有受试者都完成了信息前感受量表以及状态-特质焦虑量表（STAI）的特质部分。受试者听取了一段关于操作感受或操作过程的录音信息，随后完成信息后感受量表。在进行钡灌肠后，所有受试者都完成了操作后感受量表以及STAI的状态部分。在听取信息之前报告的预期感受（期望）或操作后提供的反应（实际体验）中，两组之间均无显著差异。然而，在听取信息后，发现报告的预期感受存在显著差异。与接受操作过程信息的受试者相比，接受操作感受信息的受试者报告的焦虑显著更少，且期望与他们的实际体验更一致。
