A Study of the Sensitivity According to Changes of C-AMP and STAI to Stressor

暴露于大于70 dB（A）的噪声后，人血浆C-ABP显著升高。我们认为，血浆C-AMP可以作为一个敏感的指标，在日常生活环境中的人类噪声相关的压力。本研究采用Spielberger等开发的状态焦虑量表（STAI），对状态焦虑（A-State）和特质焦虑（A-Trait）两个量表的信度和效度进行了研究，并在不同条件下进行了检验。我们已经观察到，在超过75 dB（A）的每个噪声水平下，A状态分数显著增加。我们得出的结论是，STAI是非常有效和可靠的，特别是A状态量表，是一个很好的指标，男人的心理状态下的临时压力的条件。为了研究C-AMP和A-状态作为应激指标的一致性及其系数，我们对许多女性学生志愿者暴露90 dB（A）粉红噪声，并测定比值（log（噪声暴露后血浆C-AMP/噪声暴露前C-AMP）和log（噪声暴露后A-状态/噪声暴露前A-状态））。当对照组C-AMP或A-状态指标均在95%以上时，噪声组C-AMP筛查的敏感性为71%，A-状态筛查的敏感性为27%。C-AMP比值（生理指标）较A状态比值（生理指标）敏感。A-Trait是指焦虑倾向的相对稳定的个体差异。但C-AMP升高率与A性状无明显相关性。用STAI-A-Trait很难区分对压力敏感的人和许多人。

Plasma C-ABP in humans increased significantly after exposure to noise greater than 70 dB(A). We suggest that plasma C-AMP could be useful as a sensitive index for noise-related stress in the daily living environment of humans. By using the STAI developed by spielberger et al. we have investigated the validity and reliability of two scales, that is, State Anxiety(A-State) and Trait-Anxiety(A-Trait), and the same time have examined them under various conditions. We have observed a significant increase of A-State scores at each noise level over 75 dB(A). We have reached the conclusion that the STAI is very valid and reliable, and that the A-State scale, especially, is a very good indicator fo men's psychological states under conditions of temporary stress. To study the agreement of C-AMP and A-State as a stress index and their efficients, we exposed 90 dB(A) pink noise to many female student volunteers and determined ratios ( log(post-noise exposure plasma C-AMP/pre-noise exposure C-AMP) and log(post-noise exposure A-State/pre-noise exposure A-State)). When criterias by C-AMP or A-State were values in 95%ile in contol group, the seneitivity of C-AMP to screen in noise group was 71% and the sensitivity of the A-State was 27%. The ratio of C-AMP ( physiological index) was better sensitivity than the retio of A-State (phychological index). A-Trait refers to relatively stable individual differences in anxiety proneness. But there was no significant correlation between a increase rat e of C-AMP and A-Trait. It was difficult to divide s responsive person to stress from many pepole by using STAI-A-Trait.
