目的 研究强噪声作业对作业工人人格特征的影响。方法 使用艾森克个性问卷 (EPQ)对纺织厂 2 0 0 0多名在职一线工人 (其中男性工人 45 6名 ,女性工人 1683名 )的个性特征进行评价 ,研究人群按接触噪声的不同程度分为四个组 [<70、70～ 84、85～ 94、≥ 95dB(A) ]并按不同性别采用方差分析对其评定 ,接噪工龄对个性特征的影响用控制年龄的协方差分析。结果 在病理人格倾向及情绪稳定性方面 ,随着噪声强度的增加 ,得分有逐渐增加的趋势 ,尤其是在接噪强度 95dB以上组 ,这说明强噪声作业可能对从业人员病理人格倾向的发展有促进作用 ,噪声作业人员情绪趋向于不稳定。通过控制年龄的协方差分析发现 ,除情绪稳定量表得分与接噪年限有关外 (主要表现在接噪初期情绪不稳的得分高于其它组 ) ,病理人格倾向、内外向、及效度的得分与接噪年限并没有关联。结论 强噪声作业对作业人员人格特征有不良影响 ,但不具有时间剂量上的累积效应。
Objective To study the effect of strong noise on the personality of workers. Methods The eysenck personality questionnaire (EPQ) was used to evaluate the personality characteristics of more than 200 on-the-job front-line workers (456 male workers and 1683 female workers) in textile mills. The study population according to different levels of exposure noise For the four groups [<70,70 ~ 84,85 ~ 94, ≥ 95dB (A)] and according to different gender using analysis of variance to assess the impact on the personality characteristics of the noise-using covariance analysis of control age. Results In the pathological personality tendencies and emotional stability, the scores tended to increase with the increase of noise intensity, especially in the group of above 95dB, which indicated that the strong noise operation may have an impact on the development of pathological personality tendencies of practitioners Promote the role of noise workers tend to be unstable. By controlling covariance analysis of age, we found that in addition to emotional stability scale score and noise-related years (mainly reflected in the beginning of the noise emotional instability score higher than the other groups), pathological personality tendencies, internal and external, and validity There is no correlation between the score and the duration of the noise. Conclusion Strong noise has adverse effects on the personality of workers, but does not have the cumulative effect of time dose.
