Description Aim:To develop and validate a new, in the Czech language still missing test of functional communication for patients with aphasia. Methods: Functional Communication Questionnaire (FCQ) comprises 20 items that evaluate communication in four areas of real situations: I. Basal communication, IL Social communication, Ill. Reading and writing, and IV. Calculation and orientation. Every item is evaluated on 6-degree scale (0-5 points), and the sum (Functional Communication Index - FCI) of 100 points represents maximum possible value. FCQ was validated in groups of healthy volunteers (n = 110, median age 63 years), patients with aphasia (n = 38, median age 62 years), and patients with Alzheimer dementia (AD) (n = 8, median age 81.5 years). Results: Values of FCI correlated significantly with age (Spearman r = -0.354, p = 0.000148); and different normal limits of FCI were established for decades: 50-59 years: >90; 60-69 years: > 85; 70-79 years: > 76. Using ROC analysis we confirmed high diagnostic validity of FCQ in discrimination between healthy controls and patients with aphasia (sensitivity of 89.5% and specificity 01 93.6% for cut-off value 86.5; AUC = 0.974; p <0.001). Degree of functional communication impairment quantified with FCI in patients with aphasia correlated with the degree of language deficit quantified with MASTcz, while there was no significant difference in FCI values between patients with aphasia and AD. Repeated evaluation in 10 patients with aphasia proved very high test-retest reliability of FCQ. New therapeutic material based on FCQ was finally introduced into clinical practice. Conclusion: FCQ extends the repertoire of diagnostic tests for patients with aphasia available in the Czech language. Our results showed very good psychometric characteristics of FCQ that should be confirmed by further research.
