Broader use of standardized psychological testing for applicants submitting disability claims to the U.S. Social Security Administration (SSA) should improve the accuracy and consistency of disability determinations, says a new report from the Institute of Medicine. Some proponents of mandatory psychological testing, in particular validity testing, for SSA disability applicants argue that it would result in a significant reduction of individuals allowed onto the benefits rolls and a substantial cost savings. The committee that conducted the study and wrote the report said the data necessary to accurately assess the effects on the rolls or calculate financial costs and benefits are limited, and estimates based on available data are subject to considerable error. ...
Cognitive psychological tests are performance-based and have people answer questions and solve problems as well as they possibly can. Non-cognitive psychological tests are measures of typical behavior -- such as personality, interests, values, and attitudes. Validity tests can be used in conjunction with these standardized psychological tests to assess whether a test-taker is exerting sufficient effort to perform well, responding to the best of his or her capability, or providing an accurate report of his or her symptoms. ...
The committee recommended that under specified conditions, SSA should require standardized, non-cognitive psychological testing for all applicants whose allegation of non-cognitive functional impairment relates to a mental disorder unaccompanied by cognitive complaints or to a disorder with physical symptoms that are disproportionate to the medical findings. Testing should be required when the allegation is based primarily on the applicant's self-reporting of symptoms and is not accompanied by objective medical evidence or longitudinal medical records sufficient to make a disability determination. In addition, the SSA should require standardized cognitive testing be included in the case record for all applicants whose allegation of cognitive impairment is not accompanied by objective medical evidence. ...
