The brief pain inventory-Interference Subscale has acceptable reliability but questionable validity in acute back and neck pain populations.

ABSTRACT:

Background

The Brief Pain Inventory-Interference Subscale (BPI-IS) is a subscale of the BPI assessment tool developed to rapidly assess the impact of a person's pain on their function. It is uncertain whether it has one or two factors, and whether it has acceptable clinimetric properties in a mixed spinal pain (back and/or neck) population.

Objectives

To determine the clinimetric properties of the BPI-IS in a population with mixed spinal pain.

Methods

We completed a clinimetric evaluation with a test-retest design, factor analysis, and hypothesis testing. We used data collected for a randomised clinical trial including a population presenting to primary care or emergency departments with acute spinal pain (back and/or neck).

Results

Confirmatory factor analysis
