Test–retest reliability of the Turkish translation of the Penn Computerized Neurocognitive Battery

Psychiatric disorders are associated with cognitive dysfunction (CD), and reliable screening and follow-up of CD is essential both for research and clinical practice globally; yet, most assessments are in Western languages. We aimed to evaluate the test–retest reliability of the Turkish version of the Penn Computerized Neurocognitive Battery (PennCNB) to guide confident interpretation of results. Fifty-eight healthy individuals completed the PennCNB Turkish version in two sessions. After quality control, reliability analysis was conducted using Intraclass Correlation Coefficients (ICC), corrected for practice effects. Most measures were not significantly different between the sessions and had acceptable ICC values, with several exceptions. Scores were improved considerably for some memory measures, including immediate Facial Memory and Spatial Memory, and for incorrect responses in abstraction and mental flexibility, with correspondingly acceptable ICCs. Test–retest assessment of the Turkish version of the PennCNB shows that it can be used as a reliable real-time measurement of cognitive function in snapshot cross-sectional or longitudinal determinations. Preliminary validity assessment in this normative sample showed expected positive correlations with education level and negative correlations with age. Thus, the Turkish version of the PennCNB can be considered a reliable neuropsychological testing tool in research and clinical practice. Practice effects should be considered, especially when applied in short intervals. Significantly better performances in the retest, beyond practice effect, likely reflect nonlinear improvements in some participants who “learned how to learn” the memory tests or had insight on solving the abstraction and mental flexibility test.

精神障碍与认知功能障碍（Cognitive Dysfunction, CD）密切相关，在全球范围内的科研与临床实践中，对CD开展可靠的筛查与随访均具有重要意义；然而当前绝大多数认知评估工具均以西方语言为基础编制。本研究旨在评估土耳其语版佩恩计算机化神经认知测验（Penn Computerized Neurocognitive Battery, PennCNB）的重测信度，为研究结果的可靠解读提供依据。本研究招募58名健康受试者，分两次完成土耳其语版PennCNB测评。经过质量控制后，采用组内相关系数（Intraclass Correlation Coefficients, ICC）并校正练习效应，对数据进行信度分析。绝大多数测评指标在两次测评间无显著差异，且组内相关系数值处于可接受范围，仅少数指标例外。即刻面部记忆（Facial Memory）与空间记忆（Spatial Memory）等部分记忆类指标，以及抽象推理与心理灵活性任务中的错误应答数得分均有显著提升，且对应的组内相关系数值同样符合可接受标准。对土耳其语版PennCNB的重测评估结果表明，该工具可作为可靠的实时认知功能测评手段，应用于横断面或纵向研究中的即时认知快照检测。在该标准化样本中开展的初步效度评估结果显示，认知功能得分与受教育水平呈预期的正相关，与年龄呈负相关。综上，土耳其语版PennCNB可被视为适用于科研与临床实践的可靠神经心理测评工具。在使用该工具时需注意练习效应，尤其是当两次测评间隔较短时。部分受试者在重测中表现出显著优于练习效应所能解释的提升，这可能反映出部分参与者已掌握"如何学习"记忆类测评任务，或对抽象推理与心理灵活性任务的解题思路形成了清晰认知，进而出现了非线性的能力提升。
