The ability to screen Turkish-speaking older adults for cognitive impairment by phone is lacking. The aim of this study was to translate the existing version of the telephone cognitive screen (T-CogS) into Turkish version (T-CogS-TR) and evaluate its reliability and validity in community-dwelling older adults. We prospectively recruited 104 community-dwelling participants with mild to moderate Alzheimer's disease (AD) and healthy controls. The T-CogS-TR was administered twice via telephone at home, first within 3 days of an in-person administration and again 4 weeks later. We observed acceptable internal consistency (Cronbach α coefficient = 0.738) and internal reliability. The test-retest reliability was excellent. The T-CogS-TR demonstrated significant correlations with Instrumental Activities of Daily Living, Mini-Mental State Examination, Clock-Drawing Test, and Clinician Dementia Rating (P's < .0001). The cutoff value of ≤22 exhibited sensitivity of 96.8%, specificity of 90.2%, positive predictive value of 93.9%, and negative predictive value of 94.9%. The T-CogS-TR can be useful as a valid and reliable tool for detecting AD in Turkish elderly patients. Also, this tool may be considered suitable for patients who need more frequent follow-up and cannot easily return to in-person visits.

土耳其版的电话认知屏幕，用于检测老年人的认知障碍。

缺乏通过电话筛查讲土耳其语的成年人的认知障碍的功能。这项研究的目的是将电话认知屏幕（T-CogS）的现有版本转换为土耳其语版本（T-CogS-TR），并评估其在社区居住的老年人中的可靠性和有效性。我们前瞻性地招募了104位患有轻度至中度阿尔茨海默氏病（AD）和健康对照的社区居民。在家中通过电话对T-CogS-TR进行了两次给药，第一次是亲自给药后3天内，然后是4周后。我们观察到可接受的内部一致性（Cronbachα系数= 0.738）和内部可靠性。重测可靠性极好。T-CogS-TR与日常生活，迷你精神状态检查，钟表测试和临床痴呆评分（P <.0001）。截止值≤22表现出96.8％的敏感性，90.2％的特异性，93.9％的阳性预测值和94.9％的阴性预测值。T-CogS-TR可作为一种有效且可靠的工具，用于检测土耳其老年患者的AD。同样，该工具可能被认为适合需要更频繁随访且无法轻松返回面对面就诊的患者。
