ABSTRACT

Introduction

Few self-administered outcome measures are available for communication partner training (CPT) programs for aphasia. The Aphasia Attitudes, Strategies, and Knowledge (AASK) survey was developed to align with and evaluate three key ingredients of the Supported Conversation for adults with Aphasia (SCA™) communication partner training model. The AASK is a new, clinically feasible tool that provides the option of flexible administration contexts, particularly with university-based student health professionals.

Aim

As the first step of psychometric evaluation, this paper addresses the aim of evaluating test-retest reliability of the AASK survey.

Methods and Procedures

Test–retest reliability of the survey was evaluated with responses from 52 allied health student health professionals (including physiotherapists, occupational therapists, and rehabilitation counsellors) at The University of Sydney . Participants completed the survey at two time points, either in-person or digitally. The AASK survey contains three sections that correspond with the three key ingredients of SCA™: knowledge of aphasia, understanding of strategies to facilitate communication with people with aphasia, and attitudes towards communicating with people with aphasia. Each of these three sections and the 11 items were tested for reliability using Kendall’s Coefficient of Concordance.

Outcomes and Results

The survey response rate was 89.66%. Ten of the eleven items of the AASK survey had a Kendall’s W above 0.61, corresponding with strong to very strong test–retest reliability. Kendall’s W was equal to or above 0.70 for all sections of the AASK survey, again within the range of strong to very strong test–retest reliability.

Conclusions

The AASK survey was developed as a clinically feasible tool that evaluates CPT knowledge of aphasia and SCA™ communication strategies as well as confidence interacting with individuals with aphasia. In this study, the AASK survey was found to have strong stability, which is one of the important psychometric properties required for an evidence-based CPT outcome measure.

对学生健康专业人员进行的失语态度、策略和知识 (AASK) 调查的重测信度

摘要

介绍

很少有自我管理的结果测量可用于失语症的沟通伙伴培训 (CPT) 计划。失语症态度、策略和知识 (AASK) 调查旨在与成人失语症 (SCA™) 沟通伙伴培训模型的支持对话的三个关键要素保持一致并对其进行评估。AASK 是一种新的、临床上可行的工具，它提供了灵活的管理环境选项，特别是与大学学生健康专业人员。

目的

作为心理测量评估的第一步，本文旨在评估 AASK 调查的重测信度。

方法和程序

该调查的重测信度通过悉尼大学 52 名联合健康学生健康专业人员（包括物理治疗师、职业治疗师和康复顾问）的回答进行评估。参与者在两个时间点完成了调查，无论是面对面的还是数字化的。AASK 调查包含与 SCA™ 的三个关键要素相对应的三个部分：失语症的知识、促进与失语症患者交流的策略的理解以及与失语症患者交流的态度。这三个部分中的每一个部分和 11 个项目都使用 Kendall 的一致性系数进行了可靠性测试。

结果和结果

调查回复率为89.66%。AASK 调查的 11 项中有 10 项的 Kendall's W 高于 0.61，对应于很强到非常强的重测信度。对于 AASK 调查的所有部分，Kendall's W 等于或高于 0.70，同样在强到非常强的重测信度范围内。

结论

AASK 调查是作为临床上可行的工具开发的，用于评估 CPT 对失语症和 SCA™ 沟通策略的知识以及与失语症患者互动的信心。在这项研究中，发现 AASK 调查具有很强的稳定性，这是基于证据的 CPT 结果测量所需的重要心理测量特性之一。
