The four square step test in children with Down syndrome: Reliability and concurrent validity.

Verma A, Samuel AJ, Aranha VP - J Pediatr Neurosci (2014 Sep-Dec)

Bottom Line: FRT was used as the criterion dynamic balance measure to validate FSST.The Bland-Altman limits of agreement were also satisfied.Concurrent validity between FRT and FSST with Spearman's ρ = -0.58 (-0.86 to -0.13).

ABSTRACT

Purpose: To estimate test-retest reliability, inter-rater reliability and validation of a method for measuring balance by stepping over four squares, four square step test (FSST) in children with Down syndrome (DS).

Methods: A sample of 13 children with DS was recruited for the cross-sectional study. They were asked to perform FSST and the time taken was noted. For estimating test-retest reliability, FSST was done by principal investigator twice and Inter-rater reliability was assessed by principal investigator and second investigator with an interval of 7 days. FRT was used as the criterion dynamic balance measure to validate FSST. The data was tabulated and analysed statistically.

Results: The test-retest reliability and inter-rater reliability of FSST are ICC(1,1) = 0.70 (0.64-0.90) and ICC(2,1) = 0.78 (0.62-0.91) respectively. The Bland-Altman limits of agreement were also satisfied. Concurrent validity between FRT and FSST with Spearman's ρ = -0.58 (-0.86 to -0.13).

Conclusion: FSST has moderate to good concurrent validity and good reliability among the children with Down syndrome.

Figure 7: Correlation Scatter block between FRT and FSST. According Shrout and Fleiss JL criteria there is moderate degree of inverse association between FRT and FSST with Spearman's ρ-0.58 (P=0.03)

Mentions: The concurrent validity of FSST with the dynamic balance measure is displayed in Figure 7. According to Porteney and Watkins criteria in judging the relationship, there is moderate degree of inverse association between FRT and FSST with Mean Spearman's ρ −0.58 (P = 0.03).
