To address the paucity and potential of context-based prospective memory (PM) assessment tasks suitable to Indian ethnicity, the study aimed to develop a novel context-based PM task and determine its psychometric properties among neurotypical adults.
Rendered images in 2-D were extracted from a 3-D shopping mall, where PM and ongoing tasks were embedded within them to provide participants with a semi-immersive experience. The design and scoring of the novel task were constructed in alignment with the Memory for Intentions Screening Test. Fifty neurotypical adults in and around Mangaluru were recruited. The Memory of Intentions Test (MIST) and novel context-based PM task were administered.
The validity of the novel task was established with a Content Validity Index of 0.98. The intraclass correlation for the test-retest reliability of the novel context-based PM task was 0.92 (p<0.001) and the inter-rater reliability was 0.98 (p<0.001). The internal consistency of the six subscales was high (Cronbach's α= 0.86), and the Spearman-Brown coefficient indicated a strong split-half reliability of 0.87. Spearman's correlation showed that the trials exhibited strong connections to the dichotomic characteristics of the subscales to which they belonged. Further, McNemar's test suggested similar profiles of the participants for the MIST and novel task.
The results of the present study suggest that the novel context-based PM task offers good validity and reliability measures, providing valuable insight into the mechanisms of PM, and therefore, could be ideal for inclusion in a battery of cognitive assessments.
针对适合印度种族的基于上下文的前瞻性记忆 (PM) 评估任务的缺乏和潜力，本研究旨在开发一种新的基于上下文的 PM 任务，并确定其在神经典型成年人中的心理测量特性。
从一个 3D 购物中心中提取 2D 渲染图像，其中 PM 和正在进行的任务嵌入其中，为参与者提供半沉浸式体验。新任务的设计和评分与意图记忆筛查测试一致。在芒格洛尔及其周边地区招募了 50 名神经典型成年人。进行了意图记忆测试 (MIST) 和新的基于上下文的 PM 任务。
新任务的有效性通过内容效度指数 0.98 得到确立。新的基于上下文的 PM 任务的测试-重测信度的组内相关系数为 0.92（p<0.001），评分者间信度为 0.98（p<0.001）。六个分量表的内部一致性很高（Cronbach's α= 0.86），Spearman-Brown 系数表明强分半信度为 0.87。Spearman 相关表明试验与所属子量表的二分特征之间存在很强的联系。此外，McNemar 检验表明 MIST 和新任务的参与者具有相似的特征。
本研究的结果表明，新的基于上下文的 PM 任务提供了良好的有效性和可靠性指标，为 PM 的机制提供了有价值的见解，因此，它可能是认知评估组合中的理想选择。
