Abstract

This study examined the efficacy of an intervention for increasing the accuracy of brain-injured clients' estimation of symptom severity, using a multiple-baseline design across six subjects. High initial predicted test scores, relative to test performance, were considered underestimations of symptom severity. An estimation technique (similar to Youngjohn & Altman, 1989) and explicit positive reinforcement for decreases in discrepancies between predicted test scores and actual scores were used to increase awareness of memory deficits. It was hypothesized that clients' predicted scores would significantly decrease over time following treatment. Meanwhile, the predicted scores of clients not yet receiving treatment would not significantly change. Reduced differences between predicted and actual scores were clearly obtained for two of the six clients, despite no significant decreases in predicted scores. Results are interpreted in the light of threats to the study's internal validity and directions for future research are suggested.
