Validation of the Longshi scale in assessment of function in patients from different economic,educational and regional backgrounds in China

Abstract

Objective

This study validates performance of the Longshi scale against modified Barthel index in assessment of function in patients from different economic, educational and regional backgrounds in China.

Design

This is a cross-sectional study.

Setting

One hundred and three hospitals and rehabilitation institutions across China.

Participants

A total of 14,752 patients with physical and cognitive impairments were enrolled and classified to five educational levels and five family income levels; 8060 participants were further selected from five regions to study regional influences.

Main measures

Activities of daily living were assessed with two evaluation tools, the Longshi scale and modified Barthel index. Results of evaluation with Longshi scale performed by non-healthcare workers were validated against modified Barthel index performed by healthcare workers using Pearson's correlation test.

Results

There were significant positive correlations between the findings of the Longshi scale administered by non-healthcare professionals and the modified Barthel index administered by healthcare professionals. This was true for level of education (correlations ranged from 0.697 to 0.822), family income level (correlations ranged from 0.724 to 0.761) and region (correlations ranged from 0.737 to 0.776).

Conclusion

In a large dataset of 14,752 patients, positive correlations were found between Longshi scale and modified Barthel index measures of function. Positive correlations persisted across subgroup analysis of groups from different social, economic and regional backgrounds, and with administration by non-healthcare professionals.
