The adaptation process involved translation, back\u2010translation, expert review, and pilot testing. Participants were assessed using the CETI\u2010TR, the Language Assessment Test for Aphasia (LATA), and Quick Aphasia Battery\u2010Turkish Version (QAB\u2010TR). Internal consistency was evaluated using Cronbach's alpha. Test\u2013retest and cross\u2010informant agreement (between caregivers and clinicians) were assessed using correlation analysis and intraclass correlation coefficients (ICCs). Criterion validity was examined through correlations with LATA and QAB\u2010TR scores, while discriminant validity was evaluated by comparing individuals with and without aphasia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The CETI\u2010TR demonstrated excellent internal consistency (Cronbach's alpha = 0.984), with item\u2013total correlations ranging from 0.766 to 0.964. Test\u2013retest reliability showed high stability (ICC = 0.972). Cross\u2010informant agreement between caregivers and speech\u2010language therapists was high (ICC = 0.936), with no significant difference between ratings (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.246).
