Psychological Testing and Assessment Psychometric Methodologies and Testing Educational and Psychological Assessments

Abstract

Interpretation of cognitive test profiles is popular in school psychological training and practice but is not supported by research evidence. This special issue contains four studies that provide additional data regarding cognitive test profiles. Consistent with the largely negative research literature, detailed analysis found all four cognitive profile reports lack ing reliability, validity, or diagnostic utility; even cognitive profiles composed of com posites were psychometrically weak. These results were not surprising because ipsative methods are inferior to normative methods in cognitive assessment. Given this consistent failure of empirical validation, belief in the utility of cognitive test profile interpretations was likened to a shared professional myth and it was recommended that psychologists es chew the application of cognitive test profiles for differential diagnosis and remediation.
