Roland-Morris Disability Questionnaire
Roland-Morris Disability Questionnaire (RMDQ) · Also known as: RMDQ, Roland-Morris scale
The Roland-Morris Disability Questionnaire (RMDQ) is a brief, disease-specific self-report measure developed by Morris Roland and Ruth Morris in 1983 to assess functional disability and activity limitations in patients with acute and chronic low back pain. With 24 items addressing daily activities impacted by back pain, it has become one of the most widely used disability measures in low back pain research and clinical practice.

When to use it
The RMDQ is indicated for baseline and follow-up assessment of low back pain patients in primary care, physiotherapy, orthopedic, pain management, and occupational health settings. It is ideal for longitudinal tracking of functional status during treatment (physical therapy, manipulation, exercise programs, pharmacological interventions), research investigating low back pain outcomes and prognostic factors, and clinical decision support regarding readiness for return to work. The questionnaire is particularly valuable for acute and subacute low back pain where rapid functional recovery is expected. It is less sensitive to capturing disability from upper extremity or lower extremity pain and should not be used for non-spine pain conditions.
Strengths & limitations
- Brief and practical: 24 items requiring only 2-5 minutes, facilitating routine clinical administration and repeated measures without burden
- Strong psychometric properties: internal consistency (Cronbach's α ≥ 0.80-0.95), test-retest reliability (r ≥ 0.85-0.99), good convergent validity with other disability measures and clinical outcomes
- High sensitivity to change: responsive to both improvement and deterioration over weeks to months, enabling detection of clinically meaningful outcome shifts
- Extensively validated across 60+ languages and diverse low back pain populations (acute, chronic, occupational, surgical), with established cutoffs for risk stratification and prognosis
- Free and publicly available; no licensing or copyright restrictions
- Disease-specific to low back pain; not validated or appropriate for cervical pain, upper extremity pain, or generalized pain conditions
- Dichotomous (yes/no) response format lacks granularity—cannot distinguish between mild and severe limitation in individual activities
- Does not assess pain intensity, pain quality, or psychological factors (fear-avoidance, catastrophizing) that drive functional disability
- Recall bias potential—asking respondents to report restrictions over past 24 hours or past week may introduce inaccuracy, particularly in older patients or those with cognitive impairment
Frequently asked
What is the minimal clinically important difference (MCID) I should expect?
The MCID for RMDQ varies by baseline severity and population. For acute low back pain, a 2-5 point improvement is typically meaningful. For chronic back pain, MCID may be slightly higher (3-5 points) due to baseline expectations. For patients with severe baseline disability (RMDQ 15-24), even a 4-6 point improvement may represent clinically meaningful functional gain. Always interpret change in context of the patient's baseline, goals, and clinical judgment rather than applying a single rigid threshold.
Can I use RMDQ for cervical (neck) or thoracic pain?
No. The RMDQ is specifically designed and validated for low back pain. The 24 items reference low back pain-specific activities (e.g., bending, lifting). Use disease-specific measures for neck pain (Neck Disability Index) or generalized spinal pain instruments. Applying RMDQ to non-lumbar pain may produce invalid scores.
How often should I administer RMDQ in clinical practice?
Frequency depends on context. For acute low back pain in physiotherapy, weekly or biweekly assessment (every 1-2 weeks over 8-12 weeks) captures functional trajectory. For chronic pain management, monthly or quarterly assessment (every 3-6 months) tracks longer-term trends. Too-frequent assessment (daily) risks floor/ceiling effects. Establish a baseline before treatment and repeat at consistent intervals.
Does a score of 0 mean the patient is completely better?
RMDQ score of 0 indicates no functional disability from back pain—all activities are unrestricted. However, the patient may still report mild pain or mild discomfort that does not limit activity. Some patients require pain-free status for functional independence; others accept mild residual pain if activity is unrestricted. Always clarify the patient's functional goals and pain expectations alongside RMDQ interpretation.
