The assessment of self-care among older adults is important as it permits the tailoring of educational interventions directed to prevent health deterioration and contrast the effects of ageing. The Self-care Ability Scale for the Elderly (SASE) was developed to assess the perceived self-care ability in older adults. Its psychometric properties were tested only in Scandinavian countries and China. This research was a cross-validation of the SASE on 402 Italian adults aged 65 and older recruited in hospitals, clinics and homes, from September 2016 to February 2017. We performed exploratory and confirmatory factor analyses on two subsamples and identified three factors, self-care ability to perform ADLs, self-care ability to achieve well-being and self-care ability to set personal goals, with a good model fit (CFI > 0.93; RMSEA = 0.07; SRMR = 0.06). We eliminated four items, however, to improve the structural validity. Internal consistency for the three factors of the Italian version of the SASE (SASE-I) ranged from 0.72 to 0.92. The test-retest reliability indicated good stability of the scale (ICC coefficient = 0.92). We assessed convergent validity by comparing the SASE-I with the Katz Index of Independence in Activities of Daily Living and the Lawton Instrumental Activities of Daily Living Scale, showing moderate-to-strong correlations. In addition, the SASE-I discriminated the self-care ability in groups with different ages, levels of education and settings. Our study produced a 13-item version of the SASE with good psychometric properties that could be recommended for use in clinical practice and research after further validation on different populations and settings.
对老年人的自我护理进行评估很重要，因为这有助于量身定制旨在预防健康恶化和对抗衰老影响的教育干预措施。老年人自我护理能力量表（SASE）旨在评估老年人自我感知的自我护理能力。其心理测量特性仅在斯堪的纳维亚国家和中国进行过测试。本研究是对SASE的交叉验证，研究对象为2016年9月至2017年2月在医院、诊所和家庭中招募的402名65岁及以上的意大利成年人。我们对两个子样本进行了探索性和验证性因素分析，确定了三个因素，即进行日常生活活动的自我护理能力、实现幸福感的自我护理能力和设定个人目标的自我护理能力，模型拟合良好（CFI>0.93；RMSEA = 0.07；SRMR = 0.06）。然而，为了提高结构效度，我们删除了四个项目。意大利版SASE（SASE-I）三个因素的内部一致性范围为0.72至0.92。重测信度表明该量表具有良好的稳定性（ICC系数 = 0.92）。我们通过将SASE-I与日常生活活动能力的Katz独立指数和Lawton日常生活工具性活动量表进行比较来评估收敛效度，结果显示出中度至高度的相关性。此外，SASE-I能够区分不同年龄、教育水平和环境的人群的自我护理能力。我们的研究得出了一个包含13个条目的SASE版本，其具有良好的心理测量特性，在对不同人群和环境进行进一步验证后，可推荐用于临床实践和研究。
