OBJECTIVE: To estimate the smallest real difference (SRD) values of 2
instrumental activities of daily living measures (the Nottingham Extended
Activities of Daily Living [NEADL] and the Frenchay Activities Index [FAI]) in
patients with chronic stroke. DESIGN: Test-retest reliability study. SETTING:
Physical rehabilitation units of 5 hospitals. PARTICIPANTS: Chronic stroke
patients (N=52; 37 men, 15 women) who were discharged from the hospital for more
than 6 months. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Both
measures were administered twice about 2 weeks apart to participants. The SRD was
calculated on the basis of standard error of measurement: SRD = 1.96 x radical2 x
Standard error of measurement. SRD% (the value of SRD divided by total score of a
measure) was used to compare measurement errors across both measures.
Reproducibility between successive measurements of the measures was investigated
with intraclass correlation coefficients (ICCs). RESULTS: The SRD (SRD%) values
of the NEADL and the FAI were 12.0 (21.1%) and 6.7 (14.9%), respectively.
Test-retest reproducibility of both measures was high (ICC: NEADL=.89, FAI=.89).
CONCLUSIONS: Because of substantial SRD values of the NEADL and the FAI,
prospective users should be cautious in using both measures to detect real change
for a single subject.
