Abstract

Objectives

This study aimed to identify the strongest predictors of self-perceptions of aging (SPA) from an extensive set of 55 variables, including demographic, psychological, social, and economic factors.

Methods

Data were drawn from the English Longitudinal Study of Ageing, comprising over 7,000 adults aged 50 and older. Two advanced machine learning models, Random Forest and extreme gradient boosting (XGBoost), were used for data analysis. This approach allowed for a comprehensive evaluation of the relative importance of each predictor.

Results

Psychological factors emerged as the strongest predictors of positive SPA, outweighing health-related and demographic variables. Sense of control was identified as the strongest predictor, followed by pleasure derived from daily life experiences and the perception of life as worthwhile. Other significant predictors included components of emotional well-being (e.g., anxiety and happiness), autonomy, self-realization, and the quality of interpersonal relationships.

Discussion

The results indicate that a sense of competence, autonomy, and relatedness forms a vital foundation for positive self-perceptions of aging. These factors are enhanced by both hedonic and eudaimonic experiences, which contribute to the emotional and existential richness of the aging process. The findings highlight opportunities for targeted interventions and the refinement of existing theoretical models.
使用机器学习识别英国老年人对衰老自我认知的预测因素
本研究旨在从55个变量(包括人口统计、心理、社会和经济因素)中确定对衰老自我感知(SPA)的最强预测因子。方法数据来自英国老龄化纵向研究,包括7000多名50岁及以上的成年人。使用随机森林和极端梯度增强(XGBoost)两种先进的机器学习模型进行数据分析。这种方法允许对每个预测因子的相对重要性进行综合评估。结果心理因素是SPA阳性的最强预测因子,超过了健康相关和人口统计学变量。控制感被认为是最强的预测因子,其次是来自日常生活经历的快乐和对生活价值的感知。其他重要的预测因素包括情绪健康成分(如焦虑和快乐)、自主性、自我实现和人际关系质量。研究结果表明,能力感、自主性和亲缘性构成了积极的衰老自我认知的重要基础。这些因素被享乐和幸福的经历所增强,这有助于衰老过程中情感和存在的丰富性。这些发现强调了有针对性的干预和改进现有理论模型的机会。

期刊介绍: Archives of Gerontology and Geriatrics provides a medium for the publication of papers from the fields of experimental gerontology and clinical and social geriatrics. The principal aim of the journal is to facilitate the exchange of information between specialists in these three fields of gerontological research. Experimental papers dealing with the basic mechanisms of aging at molecular, cellular, tissue or organ levels will be published. Clinical papers will be accepted if they provide sufficiently new information or are of fundamental importance for the knowledge of human aging. Purely descriptive clinical papers will be accepted only if the results permit further interpretation. Papers dealing with anti-aging pharmacological preparations in humans are welcome. Papers on the social aspects of geriatrics will be accepted if they are of general interest regarding the epidemiology of aging and the efficiency and working methods of the social organizations for the health care of the elderly.
