Abstract

Subjective cognitive decline (SCD) has been considered a high-risk group preceding mild cognitive impairment (MCI). However, methods to quantify and track the complaints have not been well-established. The present study aimed to develop a questionnaire tailored for Mandarin-speaking individuals with SCD. A total of 175 adults aged above 55 years completed a comprehensive set of items evaluating cognitive problems and neuropsychological examinations. After item reduction, internal consistency, construct, and concurrent validity were examined. The 14-item Subjective Cognitive Decline Scale (SCDS) has acceptable internal consistency (Cronbach's α = .93) and construct validity with a three-factor structure. Individuals with SCD and MCI scored higher than the control group. The SCDS demonstrated significant but small correlations with multiple cognitive tests and emotional variables. The SCDS provides an alternative approach to measure cognitive complaints, while an influence of emotional status shall be taken into consideration when interpreting the results.

为讲普通话的人群开发主观认知能力下降量表。

主观认知能力下降（SCD）一直被认为是轻度认知障碍（MCI）之前的高危人群。然而，对主观认知衰退进行量化和追踪的方法尚未得到很好的确立。本研究旨在为讲普通话的 SCD 患者量身定制一份问卷。共有 175 名 55 岁以上的成年人完成了一套全面的认知问题评估项目和神经心理学检查。经过项目缩减后，对内部一致性、结构效度和并发效度进行了检验。14个项目的主观认知功能减退量表（SCDS）具有可接受的内部一致性（Cronbach's α = .93）和三因素结构的建构效度。SCD 和 MCI 患者的得分高于对照组。SCDS 与多种认知测试和情绪变量之间存在明显但较小的相关性。SCDS 提供了一种测量认知抱怨的替代方法，同时在解释结果时应考虑情绪状态的影响。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
