Reliable measures are required to draw meaningful conclusions regarding developmental changes in longitudinal studies. Little is known, however, about the test-retest reliability of face-sensitive event related potentials (ERPs), a frequently used neural measure in infants. The aim of the current study is to investigate the test-retest reliability of ERPs typically evoked by faces in 9-10 month...

The test-retest reliability and clinical stability of WAIS-R VIQ-PIQ differences, inter, and intrasubtest scatter were investigated in a sample of 61 normal persons 75 years and older. The test-retest coefficient was.76 for VIQ-PIQ discrepancy, ranged from.05 to.56 for the intersubtest scatter range, and from.08 to.43 for intrasubtest scatter. In terms of clinical stability, 56% of subjects mai...

This project examined some of the common constraints on reliable cognitive assessment for children over time. Repeated measures design (n = 133) was with younger (5 & 6 year old, n = 64) and older (7 & 8 year old, n = 69) children. Results showed that children’s self-concepts moderated the test-retest reliability over extended intervals for younger and older children. Social self-categorization...

This letter is essentially an addendum to Hinton-Bayre (2010), where a comparison of several models of reliable change (RC) was made. RC statistics have been developed to assess whether an individual has demonstrated statistically significant change over time or following an intervening event or treatment. Popular settings for this include sports-related concussion, brain surgery, and cardiac s...

The purpose of this study was to examine the interrater and test-retest reliability of a one-leg balance test and a tiltboard balance test. Twenty-four normally developing children aged 4 through 9 years participated in the study. Time and quality of balance on one leg and degrees of tilt on a tiltboard prior to postural adjustment were measured. Both tests were completed with eyes open and wit...

This study investigated test-retest reliability of sensor-based sit-to-stand (STS) peak power and other STS measures in young and older adults. In addition, test-retest reliability of the sensor method was compared to test-retest reliability of the Timed Up and Go Test (TUGT) and Five-Times-Sit-to-Stand Test (FTSST) in older adults. Ten healthy young female adults (20-23 years) and 31 older adu...
