Job Content Questionnaire
Also known as: JCQ, Karasek Strain Questionnaire
The Job Content Questionnaire (JCQ), developed by Robert Karasek in 1985, operationalizes the Job Strain Model, a foundational theory linking job characteristics to health outcomes. The JCQ measures job demands, decision latitude (autonomy and skill utilization), social support, and physical exertion. It identifies high-strain jobs (high demands, low control)—the most hazardous combination—and supports research linking work organization to cardiovascular disease, mental health, and occupational disability.
Key highlights
- Theoretically grounded in the well-validated Job Strain Model, with strong evidence linking job demands-control combinations to health outcomes
- Captures key job characteristics (demands, control, support) that are organizational targets for intervention, unlike individual-level measures
- Extensive research linking JCQ patterns to cardiovascular disease, mental health, and disability, enabling quantified risk communication
- Quadrant analysis provides intuitive, actionable categorization of job types and associated health risks

When to use it
The JCQ is appropriate for occupational health surveillance, job hazard assessment, ergonomic and organizational interventions, research on work organization and health, and early identification of workers in high-strain roles. It is suitable across diverse occupations and industries. It is particularly valuable in healthcare, manufacturing, service sectors, and in evaluating workplace reorganizations.
Strengths & limitations
- Theoretically grounded in the well-validated Job Strain Model, with strong evidence linking job demands-control combinations to health outcomes
- Captures key job characteristics (demands, control, support) that are organizational targets for intervention, unlike individual-level measures
- Extensive research linking JCQ patterns to cardiovascular disease, mental health, and disability, enabling quantified risk communication
- Quadrant analysis provides intuitive, actionable categorization of job types and associated health risks
- Job strain index (demands/control ratio) is sensitive to low control scores, which may inflate strain estimates; multiplicative or threshold approaches may be more appropriate
- Self-report bias; perception of demands and control may differ from objective job characteristics
- Cross-sectional data cannot establish causality; reverse causation (poor health leading to perception of low control) is possible in some contexts

Frequently asked
Is high demand always harmful, or can it be motivating?
High demand is motivating and engaging when paired with high control (decision latitude). The harmful combination is high demand with low control. Workers with autonomy, skill utilization, and support can manage high demands. Those without control experience strain.
How does the JCQ relate to burnout measures?
The JCQ measures job characteristics that contribute to burnout risk. Burnout measures (e.g., MBI) assess manifestations. The JCQ complements burnout scales by identifying organizational root causes rather than individual outcomes.
Can the JCQ be used to predict individual health outcomes?
The JCQ is better suited to identify job-level and population-level risks than individual predictions. High JCQ strain scores correlate with health risk, but many high-strain workers do not develop disease due to individual resilience and off-work resources. Use JCQ for organizational risk assessment, not clinical prediction.
How should support be incorporated into strain assessment?
Support (from coworkers and supervisors) acts as a buffer, reducing the harmful effects of high strain. Some analyses use a three-factor model (demands, control, support) rather than simple ratios. Strong support can mitigate high strain; weak support amplifies it.
