Communication of people with Parkinson's disease (PwPD) is negatively affected. For PwPD with communication difficulties, it is important to use self-assessment tools as a primary assessment approach to evaluate their perspectives on communication. It is also important to evaluate PwPDs with self-assessment scales in order to determine in which situations their communicative effectiveness is affected and to include them in the intervention plan.
To create a Turkish version of the Communicative Effectiveness Survey-Revised (CES-R), to examine its validity and reliability, and to investigate its applicability in PwPD.
The study included 106 PwPD and 106 healthy participants. The original form of the CES-R was adapted into Turkish according to international guidelines. Every participant completed the Turkish version of CES-R and the Voice Handicap Index-10 form. The adapted scale was retested 2 weeks later.
Because the Kaiser-Meyer-Olkin coefficient was 0.956 in the exploratory factor analysis of the CES-R and p < 0.01 for Bartlett's Test, the data set is 'perfectly' suitable for factor analysis. In the explanatory factor analysis applied in the CES-R scale, the total explanatory ratio of the two dimensions was determined as 63.5%, and the validity condition was met. Cronbach's alpha coefficient was 0.958 in the PwPD group and 0.955 in the control group and the scale was found to be at the 'high reliability' level.
The CES-R is a valid, reliable, and useable self-assessment scale for Turkish PwPD. Furthermore, this adaptation research was developed to assess possible communication difficulties for PwPD. With this tool, difficulties in communication skills that can be identified by a comprehensive evaluation should also be studied in the intervention processes.
What is already known on the subject Self-assessment tools are suggested as a primary use when evaluating people with Parkinson's disease (PwPD) with communication difficulties. The CES-R is one of these self-assessment scales. However, the validity and reliability study of the Communicative Effectiveness Survey-Revised (CES-R) in Turkish has not been conducted. What this paper adds to existing knowledge This study demonstrates the validity and reliability of the Turkish CES-R scale and its applicability to PwPD. Furthermore, this scale can be used in assessment procedures for possible communication difficulties for PwPD. What are the potential or actual clinical implications of this work? The scale, which is unidimensional in the literature, was found to have two dimensions with eigenvalues > 1 in the Discovery Factor analysis in this study. The first dimension was named communication in general situations (CGS) and the second dimension was named communication in difficult situations (CDS). It is thought that this scale will be useful in research and clinics for the comprehensive assessment of PwPD with communication difficulties before and after treatment.
帕金森病患者（PwPD）的沟通受到负面影响。对于有沟通困难的 PwPD，使用自我评估工具作为主要评估方法来评估他们对沟通的看法非常重要。评估 PwPD 的自我评估量表也很重要，以便确定他们的沟通效果在哪些情况下受到影响，并将其纳入干预计划。
创建土耳其语版沟通效果量表修订版（CES-R），检验其有效性和信度，并研究其在 PwPD 中的适用性。
该研究纳入了 106 名 PwPD 和 106 名健康参与者。根据国际指南，将 CES-R 的原始形式改编为土耳其语。每位参与者都完成了土耳其语版 CES-R 和语音障碍指数-10 表。两周后重新测试了改编后的量表。
由于 CES-R 的探索性因素分析中的凯泽-迈尔-奥尔金系数为 0.956，巴特利特检验的 p 值<0.01，因此数据集非常适合因素分析。在 CES-R 量表中应用的解释性因素分析中，两个维度的总解释率确定为 63.5%，满足有效性条件。在 PwPD 组中，克朗巴赫的 alpha 系数为 0.958，在对照组中为 0.955，量表处于“高可靠性”水平。
CES-R 是一种有效的、可靠的、适用于土耳其语 PwPD 的自我评估量表。此外，这项适应性研究旨在评估 PwPD 可能存在的沟通困难。使用此工具，还应在干预过程中研究通过全面评估确定的沟通技能方面的困难。
