AIM: To evaluate the test-retest reliability of the Management of Everyday
Technology Assessment (META) in a sample of people with acquired brain injury (ABI). METHOD: The META was administered twice within a two-week period to 25
people with ABI. A Rasch measurement model was used to convert the META ordinal
raw scores into equal-interval linear measures of each participant's ability to
manage everyday technology (ET). Test-retest reliability of the stability of the
person ability measures in the META was examined by a standardized difference
Z-test and an intra-class correlations analysis (ICC 1). RESULTS: The results
showed that the paired person ability measures generated from the META were
stable over the test-retest period for 22 of the 25 subjects. The ICC 1
correlation was 0.63, which indicates good overall reliability. CONCLUSION: The
META demonstrated acceptable test-retest reliability in a sample of people with
ABI. The results illustrate the importance of using sufficiently challenging ETs
(relative to a person's abilities) to generate stable META measurements over
time. Implications for Rehabilitation The findings add evidence regarding the
test-retest reliability of the person ability measures generated from the
observation assessment META in a sample of people with ABI. The META might
support professionals in the evaluation of interventions that are designed to
improve clients' performance of activities including the ability to manage ET.
