The Brazilian version of the Home Falls and Accidents Screening Tool (HOME FAST): translation, cross-cultural adaptation, validation and reliability

Abstract

Objective:

to translate and cross-culturally adapt the Home Falls and Accidents Screening Tool - HOME FAST into Brazilian Portuguese and to evaluate its construct validity and intra-and inter-rater reliability.

Method:

a cross-sectional study was carried out that included older people aged 60 years or older. Translation and cross-cultural adaptation were carried out in the following stages: 1. Translation, 2. Synthesis, 3. Back translation, 4. Expert panel (review and pre-final version), 5. Pre-testing, 6. Analysis by the expert panel and the final version of the instrument. The Berg Balance Scale - BBS was used to test construct validity (Spearman correlation coefficient). Additionally, intra-and inter-rater reliability analysis was conducted using the Intraclass Correlation Coefficient (ICC) and the Bland-Altman plot. Results were considered significant at p<0.05.

Results:

the HOME FAST-Brazil was applied to 53 older people with a mean age of 71(5) years; 79% (42) of whom were female and 21% (11) of whom were male. The translation and cross-cultural adaptation process resulted in similar versions among translations. The correlation of the total score of HOME FAST-Brazil with the BBS was ρ=-0.241, p=0.041. The reliability rate was ICC=0.99 and 0.92 (intra-and inter-rater, respectively).

Conclusion:

The HOME FAST-Brazil, translated and cross-culturally adapted to Brazilian Portuguese, was shown to have construct validity and excellent intra-and inter-rater reliability.
