Test-retest reliability of computerized neurocognitive tests can influence their clinical utility. The reliability for a commonly used computerized neurocognitive test, CNS Vital Signs, is not well established. The purpo...
متن کاملA basis for analyzing test-retest reliability.
Three sources of variation in experimental results for a test are distinguished: trials, persons, and items. Unreliability is defined only in terms of variation over trials. This definition leads to a more complet~ analysis than does the conventional one; Spearman’s contention is verified that the conventional approach--which was formulated by Yule--introduces unnecessary hypotheses. It is emph...
متن کاملA coefficient alpha for test-retest data.
Transient errors are caused by variations in feelings, moods, and mental states over time. If these errors are present, coefficient alpha is an inflated estimate of reliability. A true-score model is presented that incorporates transient errors for test-retest data, and a reliability estimate is derived. This estimate, referred to as the test-retest alpha, is less than coefficient alpha if tran...
