The Earning Capacity Assessment Form: A Study of Its Reliability

This study evaluated the reliability of the Earning Capacity Assessment Form (ECAF), using a test-retest design over a 2-week interval.Twenty-five subjects applied the ECAF to three case studies intended to represent varying levels of threat to earning capacity.Test-retest reliability coefficients measuring subjects' assessments of loss of earning capacity ranged from .85 to .97 (p < .01),with an overall correlation coefficient of .98 (p < .01).Along with prior studies attesting to the ECAF's validity, the authors suggest this study provides additional support for use of the instrument as a robust measure ofloss of earning capacity.As subjects gained experience using the ECAF, they reported its utility increased.The authors present background information about the ECAF at the onset of the article and, after reviewing this study's results, conclude with a discussion about current and planned research.
