Abstract

Background

Remote assessment through telehealth offers potential benefits for people with aphasia (PWA), particularly where in-person services are limited. However, its diagnostic validity in developing countries remains underexplored due to differences in infrastructure and digital literacy.

Aims

To compare in-person and remote administration of the Persian Diagnostic Aphasia Battery-2: Aphasia Quotient 2 (P-DAB2-AQ2) in Persian-speaking PWA and to examine participants’ technology use and satisfaction with remote assessment.

Methods

Twenty adults with mild to severe aphasia (mean age 55.85 years) completed the P-DAB2-AQ2 both in person and remotely via Skype. The test order was counterbalanced, and administration was conducted by two independent, blinded assessors. Intraclass correlation coefficients (ICCs) and Wilcoxon signed-rank tests were used to analyse score consistency across formats. Participants also completed surveys on prior technology use and satisfaction with remote assessment.

Results

ICCs indicated excellent agreement between in-person and remote AQ2 scores (0.986) and good to excellent agreement for subtests (0.834–0.981). No significant differences were found for individual subtests (p > 0.05), although the total AQ2 score was marginally higher for in-person assessments (p = 0.044). Connected speech showed the highest variability across formats, leading to aphasia type reclassification in four participants. Ten participants showed AQ2 differences > 5 points, primarily among those with severe aphasia. Despite 60% reporting low comfort with technology, 75% were satisfied with remote assessment, and no significant correlation was found between tech experience or satisfaction and performance.

Conclusions

Remote administration of the P-DAB2-AQ2 was reliable and comparable to in-person testing, supporting its clinical feasibility in Iran. However, variability in connected speech scores highlights the need for cautious interpretation. Further studies with larger samples are needed to optimize remote protocols and ensure broader applicability.

WHAT THIS PAPER ADDS

What is already known on the subject

Telehealth in speech-language pathology (SLP), particularly for aphasia assessment, has shown comparable results to in-person assessments in developed countries. However, challenges such as technological infrastructure and professional readiness hinder its widespread adoption in developing countries like Iran.

What this study adds to the existing knowledge

This study is the first to compare in-person and remote administration of the Persian Diagnostic Aphasia Battery (P-DAB) in Persian-speaking people with aphasia (PWA). It provides detailed insights into the validity of remote assessments for each subtest, highlighting which areas are less reliable when administered remotely.

What are the potential or clinical implications of this work?

The findings support the feasibility of using remote assessments to provide speech therapy services in Iran, potentially improving access to rehabilitation for PWA, especially in underserved and rural areas. This could lead to broader implementation of telehealth, ensuring timely intervention and improved quality of life for PWA.

伊朗失语症患者波斯语诊断失语症电池的在线管理

背景：通过远程保健进行远程评估为失语症患者提供了潜在的益处，特别是在面对面服务有限的情况下。然而，由于基础设施和数字素养的差异，其在发展中国家的诊断有效性仍未得到充分探索。目的比较波斯语PWA患者现场和远程波斯语诊断失语测试-2：失语商数2 （P-DAB2-AQ2）的使用情况，并考察参与者对远程评估的技术使用情况和满意度。方法20例轻重度失语症患者（平均年龄55.85岁）通过Skype和现场完成P-DAB2-AQ2测试。测试顺序是平衡的，管理是由两个独立的，盲法评估。使用类内相关系数（ICCs）和Wilcoxon符号秩检验来分析不同格式的分数一致性。参与者还完成了关于先前技术使用情况和远程评估满意度的调查。结果ICCs显示，现场与远程AQ2评分吻合良好（0.986），子测试吻合良好至极好（0.834-0.981）。在个别子测试中未发现显著差异(p >；0.05)，尽管面对面评估的总AQ2评分略高（p = 0.044）。连接语音在不同格式中表现出最高的可变性，导致四名参与者的失语症类型重新分类。10名参与者出现了AQ2差异>；5分，主要在严重失语症患者中。尽管60%的受访者表示对技术的满意度较低，但75%的受访者对远程评估感到满意，而且在技术体验或满意度与绩效之间没有发现显著的相关性。结论P-DAB2-AQ2远程给药可靠，可与现场检测相比较，支持其在伊朗的临床可行性。然而，连接语音分数的变化强调了谨慎解释的必要性。需要进一步研究更大的样本来优化远程协议并确保更广泛的适用性。本文补充的内容：关于语言病理学（SLP）的远程医疗，特别是失语症评估，已经显示出与发达国家现场评估相当的结果。然而，技术基础设施和专业准备等挑战阻碍了其在伊朗等发展中国家的广泛采用。这项研究首次比较了波斯语失语症患者（PWA）的现场和远程波斯语诊断失语症电池（P-DAB）管理。它提供了对每个子测试的远程评估有效性的详细见解，突出显示了远程管理时哪些区域不太可靠。这项工作的潜在或临床意义是什么？研究结果支持在伊朗使用远程评估提供语言治疗服务的可行性，这可能会改善残疾人获得康复的机会，特别是在服务不足的农村地区。这可能导致更广泛地实施远程保健，确保及时干预和改善PWA的生活质量。
