背景和目标：这两项研究的文章描述了一个多维度的问卷的基础上，主观老龄化建设的意识与变化（AARC）的发展和评价。AARC捕捉固有的多维性和复杂性的老龄化态度，这是密切相关的成功老龄化的指标，包括健康和well-being.Research设计和方法：在研究1中，我们产生了一个大的项目池相关的主观老化的经验，然后评估的心理测量特性的189项版本的AARC问卷的样本396名40-95岁的成年人。根据研究1的结果，我们保留了表现最好的项目，并得出了一个更简约的50个项目版本（AARC-50）。结果：研究1的因素分析表明，问卷的结构为双因素结构，代表了对年龄相关的积极（AARC-增益）和消极（AARC-损失）变化的认识，涉及五个行为领域。研究二的验证性因素分析进一步支持了这一双因素结构。在这两项研究中，AARC问卷表现出强大的心理测量学特性，包括规模和项目的可靠性，收敛和发散效度，和预测效度。一个可靠和有效的评估工具来测量AARC的收益和AARC的损失的可用性，使研究人员能够捕捉有关成年人的积极和消极的自我感知的多个行为领域的老化的详细信息，这有助于促进成功的老龄化。
Background and Objectives: This two-study article describes the development and evaluation of a multidimensional questionnaire based on the subjective aging construct Awareness of Age-Related Change (AARC). AARC captures the inherent multidimensionality and complexity of aging attitudes, which are strongly linked to indicators of successful aging, including health and well-being.Research Design and Methods: In Study 1, we generated a large item pool related to subjective aging experiences and then evaluated the psychometric properties of a 189-item version of the AARC questionnaire in a sample of 396 adults aged 40-95 years. Based on findings from Study 1, we retained the best-performing items and arrived at a more parsimonious 50-item version (AARC-50). In Study 2, the psychometric properties of the 50-item version were examined in an expanded sample of 424 adults ages 40-98.Results: Factor analyses in Study 1 indicated a two-factor structure of the questionnaire, representing the awareness of positive (AARC-Gains) and negative (AARC-Losses) age-related changes across five behavioral domains. Confirmatory factor analysis in Study 2 further supported this two-factor structure. In both studies, the AARC questionnaire demonstrated strong psychometric properties, including scale and item reliability, convergent and divergent validity, and predictive validity.Discussion and Implications: The availability of a reliable and valid assessment tool for measuring AARC-Gains and AARC-Losses allows researchers to capture detailed information about adults' positive and negative self-perceptions of aging across multiple behavioral domains, which are instrumental for promoting successful aging.
