Evidence-based assessments for people with aphasia (PWA) in Greek are predominantly impairment based. Functional communication (FC) is usually underreported and neglected by clinicians. This study explores the adaptation and psychometric testing of the Greek (GR) version of The Scenario Test. The test assesses the everyday FC of PWA in an interactive multimodal communication setting.
To determine the reliability and validity of The Scenario Test-GR and discuss its clinical value.
METHODS & PROCEDURES: The Scenario Test-GR was administered to 54 people with chronic stroke (6+ months post-stroke): 32 PWA and 22 stroke survivors without aphasia. Participants were recruited from Greece and Cyprus. All measures were administered in an interview format. Standard psychometric criteria were applied to evaluate reliability (internal consistency, test-retest, and interrater reliability) and validity (construct and known-groups validity) of The Scenario Test-GR.
OUTCOMES & RESULTS: The Scenario Test-GR shows high levels of reliability and validity. High scores of internal consistency (Cronbach's α = 0.95), test-retest reliability (intra-class coefficients (ICC) = 0.99), and interrater reliability (ICC = 0.99) were found. Interrater agreement in scores on individual items ranged from good to excellent levels of agreement. Correlations with a tool measuring language function in aphasia, a measure of FC, two instruments examining the psychosocial impact of aphasia and a tool measuring non-verbal cognitive skills revealed good convergent validity (all ps < 0.05). Results showed good known-groups validity (Mann-Whitney U = 96.5, p < 0.001), with significantly higher scores for participants without aphasia compared with those with aphasia.
CONCLUSIONS & IMPLICATIONS: The psychometric qualities of The Scenario Test-GR support the reliability and validity of the tool for the assessment of FC in Greek-speaking PWA. The test can be used to assess multimodal FC, promote aphasia rehabilitation goal-setting at the activity and participation levels, and be used as an outcome measure of everyday communication abilities.
希腊为失语症患者（PWA）提供的循证评估主要以损伤为基础。临床医生通常较少报告和忽视功能性交流（FC）。本研究探讨了情景测试希腊语（GR）版本的改编和心理计量学测试。该测试在互动多模态交流环境中评估 PWA 的日常 FC。
确定情景测试-GR 的可靠性和有效性，并讨论其临床价值。
对 54 名患有慢性中风（中风后 6+个月）的人进行了情景测试-GR 测试：32 名 PWA 和 22 名无失语症的中风幸存者。参与者是从希腊和塞浦路斯招募的。所有措施均以访谈形式进行。应用标准心理计量学标准评估情景测试-GR 的可靠性（内部一致性、重测和评分者间信度）和有效性（构念和已知组有效性）。
情景测试-GR 显示出高度的可靠性和有效性。高内部一致性分数（Cronbach's α = 0.95）、重测信度（组内相关系数（ICC）= 0.99）和评分者间信度（ICC = 0.99）。个别项目得分的评分者间一致性从良好到极好水平。与评估失语症语言功能的工具、评估 FC 的工具、评估失语症心理社会影响的两个工具和评估非言语认知技能的工具的相关性显示出良好的收敛有效性（所有 p < 0.05）。结果表明具有良好的已知组有效性（Mann-Whitney U = 96.5，p < 0.001），与无失语症的参与者相比，有失语症的参与者得分明显更高。
情景测试-GR 的心理计量学质量支持该工具在评估讲希腊语的 PWA 的 FC 中的可靠性和有效性。该测试可用于评估多模态 FC，促进在活动和参与层面为失语症康复设定目标，并可作为日常沟通能力的结果测量。
