工作内容量表（JCQ22）在噪声作业工人中的应用

Application of Chinese version job content questionnaire (JCQ22) in occupationally noise-exposed workers

    摘要
  • 摘要:
    目的 评价中文版工作内容量表（job content questionnaire，JCQ22）在噪声作业工人中的信度和效度，检验该量表应用于噪声作业人群中的可推广性。
    方法 采取自愿填写的方式，对500名某汽车制造企业噪声作业工人进行JCQ22的问卷调查，并随机抽取其中40位调查者，间隔两周后进行重复调查。问卷的信度采用内部一致性信度和重测信度进行分析；内容效度采用相关分析，结构效度采用探索性因子进行分析。
    结果 本次问卷中的工作内容量表的Cronbach's α系数为0.933，问卷的内部一致性信度较好；重复调查结果显示两次的测得得分差异无统计学意义（P>0.05），且量表中三个维度两次测评的相关系数均大于0.9（P < 0.01），说明重测一致性好；各维度得分与量表总得分的相关系数均大于0.8（P < 0.01），说明内容效度较高；探索性因子分析结果显示：KMO值为0.933，Bartlett球形检验值为7 835.941（P < 0.01），表示各变量间有一定的相关性，适合因子分析；提取4个公因子，解释的累计方差贡献率达66.583%，进行方差最大正交旋转，4个公因子的条目载荷与工作内容量表的结构框架基本一致。
    结论 中文版工作内容量表（JCQ22）具有较好的信度和效度，能够较好地反映噪声作业工人的职业紧张状况，适用于评价噪声作业工人的心理状况。

     

    Abstract:
    Objective To evaluate the applicability of the Chinese version job content questionnaire (JCQ22) in occupationally noise-exposed workers.
    Methods The occupational stress of 500 noise-exposed workers in an automobile manufacturing company were surveyed with questionnaire of JCQ22. Repeated investigations were conducted after 2 weeks among 40 workers who were selected randomly. The reliability of the questionnaire was analyzed using internal consistency reliability and test-retest reliability. Content validity was evaluated based on correlation analysis, while structural validity was analyzed using exploratory factors.
    Results The Cronbach's α coefficient of this study was 0.933 to verify the good internal consistency of the questionnaire. The results of repeated survey showed there was no statistically significant difference between the two measured scores (P>0.05). The correlation coefficient of these two surveys was greater than 0.9 to show good re-test consistency. The correlation coefficient between the scores of each dimension and the total score of the scale was greater than 0.8(P < 0.01)to indicate highly effective content. The KMO value of 0.933 and Bartlett's spherical test value of 7 835.941(P < 0.01)indicated that there was a certain correlation among variables and these variables were suitable for factor analysis. The four extracted common factors contributed 66.583% of cumulative variance. The maximum orthogonal rotation of the variance showed that the item load of the four extracted common factors was basically the same as the structural framework of the work content scale.
    Conclusion The Chinese version job content questionnaire (JCQ22) has good reliability and validity. It can better reflect the occupational stress of noise-exposed workers and be applicable to survey the mental health condition of these workers.
