This paper empirically tests the new multi-level Associationalist Demand Control (ADC) theory by applying the Job Content Questionnaire (JCQ) 2.0 that assesses both a wide range of task characteristics as well as work organizational and external-to-work psychosocial characteristics.
The paper is based on four JCQ 2.0 pilot studies among 16,125 workers in Korea, China, Australia, and Germany. All pilots used the original JCQ task-level scales and then added newly developed proposed items and scales, evolving more comprehensive higher-level scales from pilot to pilot from 2005 to 2011. A brief review of the analytic process is presented, followed by an assessment of the internal consistency and concurrent validity of the final 25 multi-level JCQ 2.0 scales at the task, the organizational, and the external levels.
Adequate psychometric properties were established for the JCQ 2.0 pilot scales. The extended set of task-level scales was found to be robust across all samples; the new organizational scales mainly showed adequate internal consistency with α > 0.7 in Australia and Germany (tested only there) and were associated with relevant work- and health-related outcome measures as expected. Similarly, the external-to-work scales (tested only in Germany) had adequate Cronbach's Alpha values and showed expected associations to relevant outcome scales.
Although not all scales were available in all countries, overall, the results support the "functional similarity" of the major scale areas across the four pilot countries and support the underlying extensions of the Demand-Control theoretical constructs to the multi-level psychosocial work assessment for the promotion of workers' health and wellbeing as suggested by the new ADC model.
本文通过应用工作内容问卷（JCQ）2.0对新的多层次关联主义需求控制（ADC）理论进行实证检验，该问卷评估了广泛的任务特征以及工作组织和工作外部的社会心理特征。
本文基于在韩国、中国、澳大利亚和德国的16125名工人中进行的四项JCQ 2.0试点研究。所有试点都使用了原始的JCQ任务级量表，然后添加了新开发的拟议项目和量表，从2005年到2011年，试点之间逐步形成了更全面的高级量表。本文简要介绍了分析过程，随后评估了最终25个多层次JCQ 2.0量表在任务、组织和外部层面的内部一致性和同时效度。
为JCQ 2.0试点量表建立了足够的心理测量学特性。发现扩展后的任务级量表在所有样本中都很稳健；新的组织量表在澳大利亚和德国（仅在那里进行了测试）主要显示出足够的内部一致性，α>0.7，并且与预期的相关工作和健康相关结果指标相关。同样，工作外部量表（仅在德国进行了测试）具有足够的克朗巴哈α值，并显示出与相关结果量表的预期关联。
尽管并非所有国家都能获得所有量表，但总体而言，结果支持四个试点国家主要量表领域的“功能相似性”，并支持需求控制理论结构向多层次社会心理工作评估的潜在扩展，以促进工人的健康和福祉，如新ADC模型所建议的那样。
