Self-care agency plays an important role in an individual's health. Considering the particularities of their education, it can be a protective factor for the mental health of medical students. This study aims to validate the Portuguese version of the Appraisal of Self-care Agency Scale-Revised (ASAS-R) in Portuguese medical students. A cross-sectional, quantitative, and analytical online study was conducted between 23 April 2021, and 15 July 2021. Exploratory factor analysis (EFA) was performed to test the internal structure of the ASAS-R. Correlations with the SHS (Subjective Happiness Scale), SWLS (Satisfaction with Life Scale), and MHI (Mental Health Inventory) were calculated using Pearson's coefficient so as to test convergent validity. Internal consistency was evaluated using inter-item correlation, corrected item-total correlation, and Cronbach's alpha. The total sample included 781 individuals. EFA yielded a 3-factor solution accounting for 53.9% of the explained variance. Pearson's coefficients obtained between the 3 factors of ASAS-R and the total scores of the 3 construct-related scales demonstrated adequate convergent validity. Total Cronbach's alpha value was 0.85, while the Cronbach's alpha of the three factors was 0.81, 0.55, and 0.83, respectively. This study demonstrated that ASAS-R is a valid and reliable instrument for measuring self-care agency among Portuguese medical students.
自我护理能力在个体健康中起着重要作用。考虑到他们教育的特殊性，它可以成为医学生心理健康的保护因素。本研究旨在验证葡萄牙版自我护理能力评估修订版（ASAS-R）在葡萄牙医学生中的适用性。这是一项在 2021 年 4 月 23 日至 7 月 15 日期间进行的横断面、定量和分析性在线研究。采用探索性因子分析（EFA）来检验 ASAS-R 的内部结构。通过皮尔逊系数计算 ASAS-R 的 3 个因子与 SHS（主观幸福感量表）、SWLS（生活满意度量表）和 MHI（心理健康量表）之间的相关性，以检验其聚合效度。采用项目间相关、校正项目总分相关和克朗巴赫 α 值评估内部一致性。总样本包括 781 人。EFA 产生了一个 3 因素解决方案，占解释方差的 53.9%。ASAS-R 的 3 个因子与 3 个与结构相关的量表总分之间的皮尔逊系数表明具有足够的聚合效度。总克朗巴赫 α 值为 0.85，而 3 个因子的克朗巴赫 α 值分别为 0.81、0.55 和 0.83。本研究表明，ASAS-R 是一种有效且可靠的工具，可用于测量葡萄牙医学生的自我护理能力。
