Validation of the functional and social performance – DSF-84 checklist: preliminary study

Abstract

Purpose: To develop, implement and validate an instrument for assessing the functional and social performance of young male adults with lower limb amputees based on the international classification of functionality, incapacity, and health. Methods: Developed the instrument, the items were grouped into domains (organic aspects – OA, daily activities – DA, performance components – PC, social participation – SP and environmental factors – EF) for statistical analysis. The implementation of the instrument was filmed for validation. Four assessors watched the films on two occasions and gave scores. Intra-class correlation was used to evaluate intra- and inter-rater reproducibility and to the internal consistency was calculated by Cronbach’s alpha and the criterion validity was assessed by Student’s t-test and the Mann–Whitney U-test. Results: The results showed good reliability in the scores for OA, DA, PC and SP domains and a reasonable reliability for the EF domain. The differences between assessors performed by the analysis of variance were not significant. The reliability intra-rater, performed through the test–retest method, showed in all domains high levels of intra-rater correspondence. Conclusions: The results show the validity and reliability of DSF-84 to young male adults with amputation of the lower limb, being useful for this population.

Implications for Rehabilitation

• In this study have been developed, implemented, and validated an instrument (DSF-84) for assessing the functional and social performance of young male adults with lower limb amputees based on the ICF.

• The results show the validity and reliability of DSF-84 to young male adults with amputation of the lower limb, being useful for this population.

• Assessment
• functional performance
