Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

科学领域:

  • 神经科学是一个神经科学.
  • 认知心理学 认知心理学
  • 老年学是一门学科.

背景情况:

  • 主动语义干扰 (PSI) 和无法从PSI中恢复 (frPSI) 是由逻辑记忆和语义学习量表 (LASSI-L) 评估的新型认知构造.
  • 这些措施对轻度认知障碍 (MCI) 和临床前阿尔茨海默氏症 (AD) 的早期认知变化敏感,可通过使用位子发射断层扫描 (PET) 通过粉样β (Aβ) 负载检测.

研究的目的:

  • 为了比较LASSI-L的新计算机化版本,称为LASSI-Brief Computerized (LASSI-BC) 的疗效,与标准的纸和笔LASSI-L.
  • 评估 LASSI-L 两种版本的诊断性能,以区分认知不受损 (CU) 的老年人和有记忆力衰竭 (aMCI) 的老年人.

主要方法:

  • 这项研究涉及110个CU和79个aMCI参与者使用纸和笔LASSI-L,与62个CU和52个aMCI参与者使用LASSI-BC相比.
  • 以共同变量调整的统计分析,包括初始学习程度,性别,教育和评估语言.

主要成果:

  • 标准和计算机化的LASSI-L版本都有效地区分了aMCI和CU参与者.
  • 拉西-BC的诊断准确度更高,ROC曲线下的面积为0.927 (灵敏度为92.3%,特异性为88.1%),而纸笔拉西-L的ROC为0.815 (灵敏度为72.5%,特异性为79.1%).
  • 这两种版本之间的表现对于CU和aMCI集团来说都是可比的.

结论:

  • 拉西-BC是一种可行的,可能优于纸和笔拉西-L的替代方案,用于评估与MCI相关的认知功能.
  • 拉西-BC提供优势,如标准化管理,适合远程评估,和音频验证的自动评分,提高其临床实用性.
