The purpose of this study was to evaluate the efficacy of a guided imagery (GI) intervention for stress reduction in pregnant African American women beginning early in the second trimester. This prospective longitudinal study of 72 women used a randomized controlled experimental design with two groups conducted over 12 weeks. The intervention was a CD with 4 professionally recorded tracts designed and sequenced to influence study variables. Participants in both GI and usual care (UC) completed measures and donated 5 cc of blood at baseline, 8 weeks and 12 weeks. Participants also completed a daily stress scale. A mixed-effects linear model tested for differences between groups for self-reported measures of stress, anxiety, and fatigue as well as corticotrophin releasing hormone (CRH), a biologic marker of stress. Significant differences in perceived stress daily scores and at week 8 but not week 12 were found in the GI group compared to UC group. The GI group reported significantly less fatigue and anxiety than the UC group at week 8 but not week 12. There were no significant differences in CRH levels between groups. Results suggest that GI intervention may be effective in reducing perceived stress, anxiety, and fatigue measures among pregnant African American women.
本研究旨在评估引导意象（GI）干预对孕中期早期开始的非裔美国孕妇减轻压力的效果。这是一项对 72 名女性进行的前瞻性纵向研究，采用随机对照实验设计，分为两组，持续 12 周。干预措施是一张 CD，其中包含 4 个专业录制的音轨，旨在影响研究变量。GI 和常规护理（UC）组的参与者在基线、8 周和 12 周时完成了测量并捐献了 5 毫升血液。参与者还完成了每日压力量表。混合效应线性模型测试了两组之间在自我报告的压力、焦虑和疲劳以及促肾上腺皮质释放激素（CRH）等应激生物标志物方面的差异。与 UC 组相比，GI 组在每日评分和第 8 周的感知压力方面存在显著差异，但第 12 周时无差异。两组之间的 CRH 水平没有显著差异。结果表明，GI 干预可能有效降低非裔美国孕妇的感知压力、焦虑和疲劳程度。
