Psychological Testing in the Service of Disability Determination


Book Description

The United States Social Security Administration (SSA) administers two disability programs: Social Security Disability Insurance (SSDI), for disabled individuals, and their dependent family members, who have worked and contributed to the Social Security trust funds, and Supplemental Security Income (SSSI), which is a means-tested program based on income and financial assets for adults aged 65 years or older and disabled adults and children. Both programs require that claimants have a disability and meet specific medical criteria in order to qualify for benefits. SSA establishes the presence of a medically-determined impairment in individuals with mental disorders other than intellectual disability through the use of standard diagnostic criteria, which include symptoms and signs. These impairments are established largely on reports of signs and symptoms of impairment and functional limitation. Psychological Testing in the Service of Disability Determination considers the use of psychological tests in evaluating disability claims submitted to the SSA. This report critically reviews selected psychological tests, including symptom validity tests, that could contribute to SSA disability determinations. The report discusses the possible uses of such tests and their contribution to disability determinations. Psychological Testing in the Service of Disability Determination discusses testing norms, qualifications for administration of tests, administration of tests, and reporting results. The recommendations of this report will help SSA improve the consistency and accuracy of disability determination in certain cases.

Performance Testing, Cognition and Assessment


Book Description

This publication contains a selection of research papers presented at the 15th Annual Language Testing Research Colloquium.This publication contains a selection of research papers presented at the 15th Annual Language Testing Research Colloquium (LTRC). The Colloquium was jointly hosted by the University of Cambridge Local Examinations Syndicate (UCLES) in Cambridge and CITO in Arnhem in the Netherlands. At the Cambridge venue, the papers were presented on the theme of performance testing and at Arnhem, they covered aspects of communication in relation to cognition and assessment. A selection of papers has been made in order to achieve a balanced coverage of these themes. In particular, the research presented includes work on speaking and writing tests where the focus is on raters and tasks; the application of various statistical methods in language test validation; and issues related to language testing in specific contexts and with particular candidate groups.




Tasks and Criteria in Performance Assessment


Book Description

This volume includes selected papers from the 28th Language Testing Research Colloquium, held at the University of Melbourne (Australia) in July 2006. The papers selected for this volume share a common theme - that of 'performance'. Not only do they focus on performance assessments of second or foreign language speaking and writing, but they also focus on the performance of the participants - the candidate (or candidates) and the raters - and the construction of that performance through the tasks and the assessment criteria.
