An International Comparative Reliability and Concurrent Validity Assessment of the Multi-Level Job Content...

Area of Science:

• Occupational Health Psychology
• Psychosocial Work Environment Assessment

Background:

• The study empirically validates the novel multi-level Associationalist Demand Control (ADC) theory.
• It utilizes the Job Content Questionnaire (JCQ) 2.0 to evaluate task, organizational, and external psychosocial characteristics.

Purpose of the Study:

• To test the multi-level ADC theory using the comprehensive JCQ 2.0.
• To assess the psychometric properties and validity of the JCQ 2.0 scales across different national contexts.

Main Methods:

• Four pilot studies involving 16,125 workers in Korea, China, Australia, and Germany were conducted between 2005 and 2011.
• The JCQ 2.0 evolved with new scales, and its internal consistency and concurrent validity were assessed at task, organizational, and external levels.

Main Results:

• The JCQ 2.0 pilot scales demonstrated adequate psychometric properties.
• Task-level scales were robust; organizational and external-to-work scales showed good internal consistency and expected associations with work and health outcomes.

Conclusions:

• Results support the functional similarity of scale areas across the four pilot countries.
• Findings validate the extension of Demand-Control constructs to multi-level psychosocial work assessment for promoting worker health and wellbeing, aligning with the ADC model.
