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可以作为人类日常生活环境中噪声相关压力的敏感指标。我们使用spielberger等人开发的STAI量表对状态焦虑（A-State）和特质焦虑（A-Trait）两个量表进行了效度和信度的研究，同时对它们在不同条件下进行了检验。我们观察到，在超过75 dB(a)的每个噪声水平下，a - state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 - state量表是一个很好的指标，男性的心理状态在暂时的压力条件下。为了研究C-AMP和a - state作为应激指标的一致性及其效率，我们对许多女学生志愿者暴露于90 dB(a)粉红噪声中，并确定了对数（噪声暴露后血浆C-AMP/噪声暴露前C-AMP）和对数（噪声暴露后a - state /噪声暴露前a - state）的比值。在对照组C-AMP和A-State指标均为95%时，噪声组C-AMP的筛选敏感性为71%，A-State的敏感性为27%。C-AMP（生理指标）比值比A-State（生理指标）比值敏感性更好。A-Trait是指相对稳定的焦虑倾向个体差异。但C-AMP的升高与a - trait之间无显著相关性。用STAI-A-Trait来区分一个对压力有反应的人是很困难的。

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.
