Occupational Stress Index
Also known as: OSI, Osipow Scale, Job Stress Measure
The Occupational Stress Index (OSI) is a comprehensive self-report measure of job-related stress and coping resources. Developed by Osipow and Spokane in 1987, the 140-item scale (abbreviated versions also exist) captures role overload, role boundary, role insufficiency, role ambiguity, physical environment demands, and coping resources. The OSI is grounded in stress and coping theory and predicts health outcomes, performance, and retention.
Key highlights
- Comprehensive multidimensional assessment of job stressors (role, environmental) and individual coping capacity, not just stress symptoms.
- Strong empirical validation: 35+ years of research shows OSI scores predict burnout, health outcomes, and performance across occupations.
- Stress-and-coping framework enables distinction between objective demands and subjective appraisal, recognizing individual differences.
- Both comprehensive (140-item) and brief (6–9-item) versions available.
- Coping resources assessment distinguishes individuals overwhelmed by stress from those with adequate adaptive capacity.

When to use it
Use the OSI in occupational health assessments, pre- and post-intervention evaluations (stress management training, job redesign), and research examining job stress outcomes. It is particularly valuable in high-stress occupations (healthcare, law enforcement, military, education, social work) where systematic stress monitoring is part of occupational health programs.
Strengths & limitations
- Comprehensive multidimensional assessment of job stressors (role, environmental) and individual coping capacity, not just stress symptoms.
- Strong empirical validation: 35+ years of research shows OSI scores predict burnout, health outcomes, and performance across occupations.
- Stress-and-coping framework enables distinction between objective demands and subjective appraisal, recognizing individual differences.
- Both comprehensive (140-item) and brief (6–9-item) versions available.
- Coping resources assessment distinguishes individuals overwhelmed by stress from those with adequate adaptive capacity.
- Length: the full 140-item version is lengthy, increasing respondent burden in high-volume surveys.
- Self-report format is vulnerable to social desirability and negative affectivity biases.
- Does not measure objective stressors or job hazards directly—it captures subjective appraisal, which may diverge from actual working conditions.
- Coping resources scale may conflate trait resilience with actual organizational support or resources available.

Frequently asked
What is the difference between stress and coping resources on the OSI?
Stress subscales measure occupational demands and strains (role overload, ambiguity, inadequate authority). Coping resources measure ability to manage demands (support, training, autonomy, career satisfaction). An individual can have high stress but adequate coping resources (stressed but managing); conversely, low stress but inadequate resources (unstressed but vulnerable).
Is a high OSI stress score a mental health diagnosis?
No. The OSI measures occupational stress and coping, not clinical psychological disorders. High OSI stress scores indicate occupational strain, which can contribute to mental health problems if prolonged, but do not diagnose depression, anxiety, or other conditions. If concerned about mental health, use clinical screening instruments and refer to mental health professionals.
Can OSI scores change based on recent work events?
Yes. OSI scores reflect current occupational stress and may fluctuate with recent events (project deadlines, staffing changes, conflicts, successes). Use longitudinal measurement to distinguish temporary fluctuations from chronic occupational strain patterns.
How do I use OSI data to reduce stress in my organization?
Identify elevated stress subscales (e.g., role ambiguity, overload) and corresponding low coping resources. Target interventions at root causes: unclear roles benefit from role clarification, overload from workload adjustment or staffing, inadequate resources from training or support programs.
Is the OSI proprietary?
The full OSI is published by Psychological Assessment Resources and is copyrighted. Access requires authorization from the publisher. Some research-only versions may be available under specific terms. The OSI-6 and OSI-9 abbreviated versions have varied availability; check the publisher's policy.
