- Abstract
Objective: We previously developed normative data for a French version of the Hayling Sentence Completion Test (f-HSCT) for adults and elderly people. The present study aimed to evaluate the clinical utility of the f-HSCT norms in two clinical populations in which inhibition dysfunction has been largely documented, i.e., Parkinson's disease (PD) and schizophrenia. Method: Eighty-five non-demented patients with idiopathic PD and 64 out-patients with schizophrenia completed the automatic and inhibition conditions of the f-HSCT. Time latencies and errors raw data of each patient were compared to the norms previously developed by the authors. Results: In the automatic condition, errors were rare in both clinical groups and time latencies on this condition felt within the normative data range. Compared with the standardized norms, 46% of patients with PD and 61% of patients with schizophrenia had a deviant performance (i.e., borderline or deficit) for the inhibition error score. The proportion of patients with a deviant performance on the inhibition response time score was similar in both clinical samples (respectively, 25% and 23%). Finally, slightly more than half of patients with PD and more than two-thirds of patients with schizophrenia had a deviant performance on at least one of the f-HSCT inhibition measures. Conclusions: Our results suggest that the f-HSCT has a strong potential for characterizing inhibition of prepotent responses in PD and schizophrenia. Furthermore, it requires only a short administration time so it may be ideal to detect response inhibition in clinical populations with cognitive fatigue.
