The purpose of this study was to characterize how individuals with Huntington disease (HD) perform on three SVTs and to examine the relationship between SVT performance and demographic and clinical variables. Results indicate that while the majority of HD patients passed the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Effort Index (EI; 82% of n = 121) and the Test of Memory Malingering (92% of n = 36), failure of these SVTs was associated with poorer cognitive and adaptive functioning, and greater motor impairment. Results showed that less than one-third passed the RBANS Effort Scale (ES; 30% of n = 43) and few clinical and demographic variables were correlated with this SVT performance. Although some SVTs may be better suited to HD, cognitive ability should be considered when evaluating effort in HD.<\/jats:p>","DOI":"10.1093\/arclin\/acs109","type":"journal-article","created":{"date-parts":[[2012,12,25]],"date-time":"2012-12-25T01:24:21Z","timestamp":1356398661000},"page":"135-143","source":"Crossref","is-referenced-by-count":15,"title":["Symptom
