The Communicative Effectiveness Index (CETI) is an informant rating scale designed to measure changes in functional communication in people with aphasia (PWA) from the carer's perspective. It offers a comprehensive view of aphasia's impact on everyday communication situations, aiding clinicians in designing personalized intervention plans. The aim of this study was to translate and adapt the CETI into Greek (CETI-GR) and validate its psychometric properties. The CETI-GR was translated into Greek using back-translation. A pilot and a content validity study ensured its acceptability. The study involved 30 people with aphasia and 30 carers. The CETI-GR's psychometric properties were evaluated, including internal consistency, test-retest reliability, inter-rater reliability, and validity measures. The CETI-GR demonstrated excellent internal consistency (Cronbach's α > 0.95) and excellent inter-rater reliability (ICC ≥ 0.93). Excellent consistency was revealed when testing the CETI responses given only by PWA (α = 0.91) versus their carers (α = 0.97). Test-retest reliability was high (ICC = 0.88). Significant correlations between the CETI-GR and measures of language severity, functional communication, and quality of life supported convergent validity. The CETI-GR is a reliable tool for assessing functional communication in chronic aphasia. Its Greek adaptation enhances aphasia rehabilitation, enabling person-centered care and improving the quality of life for people with aphasia and carers.
沟通有效性指数（CETI）是一种由信息提供者进行评分的量表，旨在从照顾者的角度衡量失语症患者（PWA）功能性沟通的变化。它全面展示了失语症对日常沟通情境的影响，有助于临床医生制定个性化的干预计划。本研究的目的是将CETI翻译成希腊语（CETI-GR）并进行改编，同时验证其心理测量学特性。CETI-GR采用回译法翻译成希腊语。一项预试验和内容效度研究确保了其可接受性。该研究纳入了30名失语症患者和30名照顾者。对CETI-GR的心理测量学特性进行了评估，包括内部一致性、重测信度、评分者间信度和效度指标。CETI-GR表现出出色的内部一致性（克朗巴哈α系数>0.95）和出色的评分者间信度（组内相关系数≥0.93）。仅由失语症患者给出的CETI回答（α = 0.91）与他们的照顾者给出的回答（α = 0.97）进行测试时，显示出极好的一致性。重测信度较高（组内相关系数 = 0.88）。CETI-GR与语言严重程度、功能性沟通和生活质量指标之间的显著相关性支持了收敛效度。CETI-GR是评估慢性失语症功能性沟通的可靠工具。其希腊语改编版增强了失语症康复效果，实现了以患者为中心的护理，并改善了失语症患者及其照顾者的生活质量。
