Validation of the cerebellar cognitive affective syndrome (CCAS) scale in CCAS patients and cerebellar controls.
Objective: The cerebellar cognitive affective syndrome (CCAS) scale has been developed to screen for possible cognitive and affective impairments in cerebellar patients, but previous studies stressed concerns regarding insufficient specificity of the scale. Also, direct comparisons of CCAS scale performance between cerebellar patients with and without CCAS are currently lacking. The aim of this study was to evaluate the validity of the CCAS scale in cerebellar patients.
Method: In this study, cerebellar patients with CCAS (n = 49), without CCAS (n = 30), and healthy controls (n = 32) were included. The Dutch/Flemish version of the CCAS scale was evaluated in terms of validity and reliability using an extensive neuropsychological assessment as the gold standard for CCAS. Correlations were examined between the CCAS scale and possible confounding factors. Additionally, a correction for dysarthria was applied to timed neuropsychological tests to explore the influence of dysarthria on test outcomes.
Results: Cerebellar patients with CCAS performed significantly worse on the CCAS scale compared to cerebellar controls. Sensitivity was acceptable, but specificity was insufficient due to high false-positive rates. Correlations were found between outcomes of the scale and both education and age. Although dysarthria did not affect the validity of the CCAS scale, it may influence timed neuropsychological test outcomes.
Conclusions: Evaluation of the CCAS scale revealed insufficient specificity. Our findings call for age- and education-dependent reference values, which may improve the validity and usability of the scale. Dysarthria might be a confounding factor in timed test items and should be considered to prevent misclassification.
期刊介绍：
The Journal of the International Neuropsychological Society is the official journal of the International Neuropsychological Society, an organization of over 4,500 international members from a variety of disciplines. The Journal of the International Neuropsychological Society welcomes original, creative, high quality research papers covering all areas of neuropsychology. The focus of articles may be primarily experimental, applied, or clinical. Contributions will broadly reflect the interest of all areas of neuropsychology, including but not limited to: development of cognitive processes, brain-behavior relationships, adult and pediatric neuropsychology, neurobehavioral syndromes (such as aphasia or apraxia), and the interfaces of neuropsychology with related areas such as behavioral neurology, neuropsychiatry, genetics, and cognitive neuroscience. Papers that utilize behavioral, neuroimaging, and electrophysiological measures are appropriate.
To assure maximum flexibility and to promote diverse mechanisms of scholarly communication, the following formats are available in addition to a Regular Research Article: Brief Communication is a shorter research article; Rapid Communication is intended for "fast breaking" new work that does not yet justify a full length article and is placed on a fast review track; Case Report is a theoretically important and unique case study; Critical Review and Short Review are thoughtful considerations of topics of importance to neuropsychology and include meta-analyses; Dialogue provides a forum for publishing two distinct positions on controversial issues in a point-counterpoint format; Special Issue and Special Section consist of several articles linked thematically; Letter to the Editor responds to recent articles published in the Journal of the International Neuropsychological Society; and Book Review, which is considered but is no longer solicited.
