Abstract

It remains a challenge to systematically and quantitatively assess the pragmatic performance of severely aphasic patients and determine severity levels. To this end, the ICRA-R Battery was designed based on the concepts of the Minimal Communication Circuit and the pragmatic features of the ICRA Method (Abraham & Brenca, 2013, 2016). It consists of four instruments. The psychometric analysis of the validation and reliability of Instrument 1 (Record and Script) and the expert-level validity of the CCA and CCP Questionnaires, which assess caregivers' perceptions of the patient's current and premorbid communicative competence, are described. Severity levels were established, and the developmental profile was graphed.
Validity was analyzed by experts (> 93.1%), factor analysis and principal components extraction, analysis of agreement between evaluators (Fleiss's Kappa > 85%; Cohen's Kappa > 95.0%, inter-observer analysis applying intraclass correlation = 0.900 (95% CI: 0.791-0.957) and repeated measures ANOVA from means and confidence intervals) and internal consistency (Cronbach's Alpha 0.966).

Keywords: Aphasia, Pragmatic Aspect, Psychometric Analysis, Basic Speech Act; Minimal Communication Circuit.
