Reviewer 1 Report
This study investigated to determine the reliability and validity of the Greek 21 version of the AIQ-21. As a result, high reliability and validity were reported. This study was significant for Greek aphasic patients. However, I have some concerns.

AIQ-21-GR was translated using PPI methodology. I think this methodology needs to be added to this section.

The sample size was compared to previous study. Why don't you calculate the sample size?

Reviewer 2 Report
This manuscript details the translation of the Aphasia Impact Questionnaire-21 (AIQ-21), a patient-reported outcome measure for aphasia, into Greek. Validation for the AIQ-21 in Greek was compared to the gold-standard tool for measuring quality of life in Greek, called the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39). Overall, the manuscript describes methods that are well motivated, well carried out, and aptly described. All comments below are minor.
Line 102: Please use the previously defined acronym “SLT” instead of “speech and language therapist,” if applicable.
Data Analysis: For each section, please ensure that the following details are specified regarding statistical significance evaluations: Correlation type (e.g., Pearson’s vs. Spearman’s) or other statistical testing type, alpha level for statistical significance, cut-offs for correlation strength, measures for effect size (please provide where applicable, I see Cohen’s d is provided for Mann-Whitney U tests later on (section 3.2.5) but without much interpretation). Some of these details are provided in one section but not others (e.g., Criterion Validity uses Spearman’s rho with clear cut-offs defined, but Translation Reliability is missing this information).
Figure 3 is quite blurry—is it possible to include a higher-resolution version?
The axes in Figure 4B are too small and very blurry—is it possible to include these subplots as a separate figure or increase the resolution of 4B as it stands?
