为考察日本版工作内容问卷(JCQ，Karasek，1985)的4个量表--决策纬度、心理需求、主管支持和同事支持的信度和效度，对日本电话和电力公司的626名员工进行了调查。调查问卷由22个项目组成。研究人员分析了472名男性受访者和10倍女性受访者的数据。克朗巴赫在四个JCQ量表上的阿尔法系数男性在0.61到0.89之间，女性在0.65到0.87之间。基于量表项目因素分析的Scree曲线图表明，一个主要因素可以解释男性和女性每个量表变异的30%到75%。男性和女性的22个条目的因子结构与理论预期一致。男性和女性在不同职业中的决策纬度得分分布与美国全国样本相似，得分与职业等级显著正相关。研究表明，JCQ量表是评估日本工作人群工作压力源的可靠而有效的工具。
To investigate the reliability and validity of 4 selected scales from the Japanese version of the Job Content Questionnaire (JCQ, Karasek, 1985)decision latitude, psychological demand, supervisor support, and coworker support-a survey was conducted on a total of 626 employees of telephone and electric companies in Japan. The survey questionnaire was composed of 22 items. Data from 472 male and 10X female respondents were analyzed. Cronbach's alpha coefficients far the four JCQ scales ranged from .61 to .89 for men and from .65 to .87 for women. Scree plots based on factor analyses of scale items indicated that one major factor explained 30% to 75% of each scale variance in men and women. Factor structures of the 22 items for men and women were consistent with those theoretically expected. Distributions of the decision latitude scores among occupations for men and women were similar to those in the U.S, national samples; the scores significantly and positively correlated with occupational class. It is suggested that the JCQ scales are reliable and valid instruments for assessing job stressors in a Japanese working population.
