Scoliosis Research Society Score (SRS 22r)

Home / REHAB SCALES / Trunk Scales / Scoliosis Research Society Score (SRS 22r)


The SRS-22r is a validated questionnaire intended to assess outcomes in patients with idiopathic scoliosis after spinal surgery. The first version, developed by the Scoliosis Research Society in 1999, had 24 items, and this was reduced to 22 items (accompanied by a name change) in the course of 3 major updates.

The measure covers 5 dimensions: pain, function, mental health, self-image and satisfaction with treatment. The SRS-22r is a valid tool for assessing patient-centered outcomes after scoliosis surgery, but has not been validated and is not intended for use for other patient populations.  A completion time of 10 minutes can be assumed.

Use the following EVALUATION FORM to evaluate your patient and PRINT THE FORM when the evaluation is completed.

Scoring method and Interpretation

  • The response to each item is associated with a point score from 1 to 5. For each of the 5 dimensions, a dimension score is calculated as the mean of the item points scored on that dimension. A total score is generated by averaging all the item points.
  • If there are unanswered items, the “questions answered” denominator is reduced by the appropriate number. Items with more than 1 answer are removed from the calculation. Except for the satisfaction with treatment dimension, the dimensions cannot be scored if fewer than 3 items are answered.
  • For the dimension and total scores, the best possible score (associated with the best health status) is 5 and the worst possible score (associated with the worst imaginable health status) is 1.
