Can we convert between outcome measures of disability for chronic low back pain?

ABSTRACT:

Study design

Retrospective database analysis.

Objective

A range of patient-reported outcomes were used to measure disability due to low back pain. There is not a single back pain disability measurement commonly used in all randomized controlled trials. We report here our assessment as to whether different disability measures are sufficiently comparable to allow data pooling across trials.

Summary of background data

We used individual patient data from a repository of data from back pain trials of therapist-delivered interventions.

Methods

We used data from 11 trials (n=6089 patients) that had at least 2 of the following 7 measurements: Roland-Morris Disability Questionnaire, Chronic Pain Grade disability score, Physical Component Summary of the 12- or 36-Item S
