in isokinetic muscle strength measurements of the shoulder.
The average-measures of [ICC.sub.AA] was 0.985 (95% confidence interval=0.969-0.993), which clearly exceeds the ICC threshold of 0.75 and confirms that there was excellent test-retest reliability
within the control subjects.
Studies on the Dutch (11) and the Serbian (15) versions measured the ICC to show test-retest reliability
. Their ICC values were 0.859 and 0.985, respectively.
The current study has indicated that the Turkish version of the PDQ-8 has high test-retest reliability
, and adequate internal consistency and convergent validity.

Quantifying test-retest reliability
using the intraclass correlation coefficient and the SEM.
The TIS had good reliability with an ICC score (ICC=0.98) for test-retest reliability
. There was no difference between the test-retest scores (p=0.08).
These techniques include test-retest reliability
, parallel or alternate forms, item-total correlation, split-half reliability, Kuder-Richardson-20, Cronbach's alpha, and inter-rater reliability (40).
All components of the NDS (current, best, worst) demonstrated good to excellent test-retest reliability
(ICC r = 0.68-0.93).
Inter-rater reliability and test-retest reliability
were assessed using a type (2,2) Intraclass Correlation Coefficient (ICC) with two-way mixed effects model at a 95% confidence interval (Shrout & Fleiss, 1979).
