This study was designed to examine the effects of preparatory cognitive and behavioral information on self-confidence, anxiety, and negative affect elicited by an impending upper gastrointestinal endoscopy.
Forty-eight male and female out-patients, between 18 and 65 years of age, scheduled for a first-time, non-emergency, endoscopic examination were randomly assigned to receive one of four experimental interventions: cognitive, behavioral, combination, or attention-control. Measures of self-reported anxiety and self-reported self-confidence were obtained.
Cognitive and combination intervention subjects were statistically younger than behavioral and attention-control subjects. A credibility assessment revealed that subjects who were taught visualization used it during their procedure. Results indicated that subjects in the cognitive and combination interventions experienced significant reduction in anxiety and increase in self-confidence from pre- to post-intervention. Self-confidence did not increase for subjects receiving the behavioral-only or the attention-control interventions.
The results of this study show that preparatory information in general is effective in reducing anxiety and in increasing self-confidence before an upper gastrointestinal endoscopy. Results suggest that teaching subjects visualization before a procedure increases their use of visualization during a procedure.
本研究旨在探讨术前认知和行为信息对即将进行的上消化道内镜检查所引发的自信、焦虑及负面影响的作用。
将48名年龄在18至65岁之间、计划进行首次非急诊内镜检查的门诊男女患者随机分为四组，分别接受以下四种实验性干预措施之一：认知干预、行为干预、联合干预或注意力控制干预。采用自我报告焦虑和自我报告自信的测量方法。
认知干预组和联合干预组的受试者在统计学上比行为干预组和注意力控制组的受试者更年轻。一项可信度评估显示，接受可视化训练的受试者在检查过程中使用了该方法。结果表明，认知干预组和联合干预组的受试者在干预前后焦虑显著降低，自信显著增强。仅接受行为干预或注意力控制干预的受试者自信并未增加。
本研究结果表明，一般而言，术前信息在减轻上消化道内镜检查前的焦虑和增强自信方面是有效的。结果表明，在检查前教导受试者进行可视化训练可增加他们在检查过程中对可视化方法的使用。
