Scale Overview
The Job Demand Control Measure was developed by Jackson, P. R., Wall, T. D., Martin, R., & Davids, K. (1993). It is designed to measure Job control, cognitive demand, and production responsibility. The scale is intended for use with Working adults.
Scale Structure
This instrument consists of 21 items organized into 5 factors/subscales: Timing control, Method control, Monitoring demand, Problem solving, Production responsibility.

Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Not at all, 2 = A little, 3 = A moderate amount, 4 = Quite a lot, 5 = A great deal.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 21 to 105. Interpretation guidelines:
- Low: 21 – 48
- Moderate: 49 – 77
- High: 78 – 105
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Timing control α = 0.85; Method control α = 0.77; Monitoring demand α = 0.73; Problem solving α = 0.50; Production responsibility α = 0.90.
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
