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

人体暴露于大于70分贝(A)的噪声后，血浆C-ABP显著升高。我们认为，血浆C-AMP可作为人类日常生活环境中噪声相关应激的敏感指标。通过使用Spielberger等人开发的STAI。我们考察了状态焦虑(A-State)和特质焦虑(A-Trait)两个量表的效度和信度，并在不同条件下对其进行了检验。我们观察到，在每个噪声级别超过75分贝(A)时，A状态分数都有显著增加。我们得出结论：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，可以反映男性在临时应激条件下的心理状态。为了研究C-AMP和A-State作为应激指标的一致性及其有效性，我们对许多女学生志愿者暴露了90分贝(A)粉色噪声，并测定了比率(噪声暴露后血浆C-AMP/噪声暴露前C-AMP)和噪声暴露后A状态/噪声暴露前A状态(LOG)。以C-AMP或A-State为标准，对照组ILI为95%时，噪声组C-AMP筛查敏感性为71%，A-State敏感性为27%。C-AMP比值(生理指标)比A-State比值(生理指标)更敏感。A特质指的是焦虑倾向上相对稳定的个体差异。但C-AMP的增高率与A-性状之间无显著相关性。用STAI-A-性状很难将S的应激反应者与许多人区分开来。

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.
