Stability reliability is concerned with the consistency of repeated measures of the same attribute with the use of the same scale or instrument over time. It is usually referred to as test-retest reliability. Because it measures the same variable in the same manner, it reveals only random error, not systematic error. Test-retest reliability requires the assumption that the factor being measured has not changed between the measurement points. Many of the phenomena studied in nursing, such as hope, coping, pain, and anxiety, do change over short intervals. Thus, it is difficult to determine whether change represents measurement error or valid change.
