概括

机器学习准确地预测了老年人焦虑的开始,使用诸如以前的抑郁,脆弱和个性特征等因素. 仅仅是先前的抑郁症诊断不足以进行预测,这凸显了对多种预测因子的需求.

科学领域:

老年学是一门学科.
心理健康心理健康
计算精神病学是一种计算精神病学.

背景情况:

焦虑障碍显著影响中年和老年人的福祉,常常由并发症和脆弱性加剧.
在这个人群中早期发现焦虑障碍对于减轻不良结果至关重要.

研究的目的:

应用机器学习 (ML) 预测老年人焦虑障碍的发病时间,提前大约三年.
用ML和Shapley基于价值的方法识别焦虑发作的关键预测因素.

主要方法:

利用了加拿大长度老龄化研究 (CLSA) 的数据.
采用了ML模型来预测未来的焦虑障碍发作.
应用了基于Shapley值的方法来确定最重要的预测因素.

主要成果:

该ML模型实现了焦虑开始的准确预测 (AUC = 0.814 ± 0.016).
关键预测因素包括先前的抑郁症/情绪障碍诊断,高脆弱性,焦虑个性和低情绪稳定性.
仅仅先前的抑郁症诊断不足以预测焦虑症的出现.

结论:

机器学习为老年人个性化的焦虑发作预测提供了一个有希望的方法.
除了先前的抑郁症诊断之外,整合多种预测因素对于提高预测准确性至关重要.
易于访问的调查数据可以有效地用于开发这些预测模型.

Longitudinal Research

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
