Abstract

Background

The Scenario Test is recognised for its effectiveness in assessing the interactive aspects of functional communication in people with post-stroke aphasia (PWA).

Aims

To develop a Japanese version of the Scenario Test (Scenario Test-JP) and assess its reliability and validity.

Methods & Procedures

Among 66 participants, we selected 61 individuals: 34 PWA and 27 healthy controls (HCs). We modified the Scenario Test-JP based on the UK version and subsequently evaluated its reliability (internal consistency, test–retest and intra-rater and inter-rater reliabilities) and validity (convergent and discriminant) by comparing PWA and HCs.

Outcomes & Results

The Scenario Test-JP showed strong reliability with a Cronbach's α of 0.93, test–retest reliability with an intraclass correlation coefficient (ICC) of 0.97, intra-rater reliability with an ICC of 0.95–1.00, and inter-rater reliability with an ICC of 0.96. The validity of the test was confirmed with concurrent scores ranging from ρ = 0.37 to 0.76 (p < 0.05) and known-groups validity (p < 0.001, r = −0.56).

Conclusions & Implications

The reliability and validity of the Scenario Test-JP align with those of the original Dutch version and the UK and Greek versions. Additionally, the assessment can now include extended alternative communication methods, such as digital devices, indicating the potential of the Scenario Test-JP for modern Japanese speech-language therapy.

WHAT THIS PAPER ADDS

What is already known on the subject

Interactive communication is a facet of functional communication and is crucial for evaluating engagement and participation of people with aphasia (PWA) in speech-language therapy. The Scenario Test provides valuable information for planning speech-language treatment strategies by assessing dialogic communication.

What this study adds

This study describes the development of the Scenario Test-JP for use with Japanese speakers and Japanese PWA, which is adapted from the Scenario Test UK version. This study evaluated the reliability and validity of this assessment tool and provided supporting evidence.

What are the clinical implications of this work?

The reliability and validity of the Scenario Test-JP were consistent with those of the Dutch, UK and Greek versions. The Scenario Test-JP contributes to speech-language therapy in Japan, where high-quality support for the activities and participation of PWA is required.

PRACTITIONER POINTS

Insights from the Scenario Test

The Scenario Test plays a crucial role in evaluating the functional communication skills of people with post-stroke aphasia (PWA). Enhancing functional communication has been linked to improved social engagement among PWA, which in turn influences their overall quality of life (QOL).

Issues addressed by the Scenario Test

The Scenario Test aids in delineating rehabilitation objectives for activities and participation among PWA, particularly concerning functional communication. The test facilitates tailored support for PWAs’ interactive communication and forms the foundation for appropriate speech-language therapy interventions.

Transformation of speech-language therapy (SLT) in Japan through the introduction of the Scenario Test-JP

The integration of the Scenario Test-JP could enhance the SLT services provided to PWA in Japan. With Japan experiencing an unprecedented ageing population, the prevalence of social isolation and diminished QOL resulting from communication disorders like stroke-induced aphasia is expected to rise. Consequently, the SLT rehabilitation sector in Japan is actively seeking effective interventions to support functional communication among PWA. Hence, the adoption of the Scenario Test-JP is anticipated to streamline the evaluation of functional communication, facilitating the judicious selection and timely provision of assistance to PWA in SLT, including guidance on communication partner support and communication skill training.

针对慢性中风所致失语症患者的日语版情景测验的信度和效度研究：一项横断面研究

背景情景测试因其在评估卒中后失语症患者（PWA）功能性交流的互动方面的有效性而得到认可。目的开发日语版情景测试（Scenario Test-JP），并评估其可靠性和有效性：在 66 名参与者中，我们挑选了 61 人：34 名 PWA 和 27 名健康对照组 (HC)。我们在英国版本的基础上修改了情景测试-JP，随后通过比较 PWA 和 HC，评估了其可靠性（内部一致性、测试-重测、评分者内部和评分者之间的可靠性）和有效性（收敛性和区分性）。结果情景测试-JP 显示出很强的可靠性，Cronbach's α 为 0.93，测试-重测可靠性（类内相关系数 (ICC) 为 0.97），评分者内部可靠性（ICC 为 0.95-1.00），评分者之间可靠性（ICC 为 0.96）。测试的有效性得到了证实，同时得分范围从 ρ = 0.37 到 0.76（p <0.05），已知群体有效性（p <0.001，r = -0.56）。此外，现在的评估还可以包括扩展的替代性交流方法，如数字设备，这表明情景测试-JP 在现代日本言语治疗中具有很大的潜力。情景测试通过评估对话性交流，为规划言语治疗策略提供了有价值的信息。本研究的补充内容本研究介绍了情景测试-JP 的开发情况，该测试由情景测试英国版改编而来，适用于日语使用者和日籍 PWA。本研究对这一评估工具的可靠性和有效性进行了评估，并提供了支持性证据。本研究的临床意义是什么？情景测试-JP 的信度和效度与荷兰语、英语和希腊语版本一致。在日本，需要为 PWA 的活动和参与提供高质量的支持，而情景测验-JP 对日本的言语治疗做出了贡献。加强功能性交流与提高 PWA 的社会参与度有关，而社会参与度的提高反过来又会影响他们的整体生活质量（QOL）。情景测试解决的问题情景测试有助于确定 PWA 活动和参与的康复目标，尤其是有关功能性交流的目标。该测试有助于为 PWAs 的互动交流提供量身定制的支持，并为适当的言语治疗干预奠定基础。通过引入情景测试，日本言语治疗（SLT）发生了转变。随着日本经历前所未有的人口老龄化，中风引起的失语症等交流障碍所导致的社会隔离和 QOL 下降的发生率预计将上升。因此，日本的 SLT 康复部门正在积极寻求有效的干预措施，以支持 PWA 的功能性交流。因此，情景测试-JP 的采用预计将简化功能性交流的评估，有助于在 SLT 中明智地选择并及时为 PWA 提供帮助，包括指导交流伙伴支持和交流技能训练。
