Simplified functioning assessment for low back pain: ICF-based item response theory modelling.

ABSTRACT:

Background

Despite the growing interest of the item response theory (IRT) in assessment of person abilities and functioning difficulties in screening tools, there is scarcity of research using IRT on ICF-based tools for persons with low back pain (LBP).

Aim

To generate and validate a parsimonious core set of ICF (PCSI) for LBP based on the IRT modelling.

Design

A cross-sectional study.

Setting

Nine hospitals in Jiangsu Province, China.

Population

We recruited patients with LBP.

Methods

All participants completed the 78 items of the comprehensive ICF Core Set for LBP. The five-point scoring system was converted to dichotomous data with 1 as functioning/independent and 0 as impairment/dependent. Psychometric properties of the data were examined usin
