Abstract

Introduction

Self-care is essential for health promotion, disease management and social justice. Robust, theory-based tools are needed for its measurement. The Self-care Inventory (SCI) was developed to measure self-care behaviours in adults regardless of their health status. The aims of this study are to measure validity of the SCI in an Italian sample and measurement equivalence in US and Italian samples.

Methods

We recruited 340 Italian and 294 US adults with convenience sampling. The Self-care Inventory, new General Self-Efficacy Scale, Positivity Scale, Perceived Stress Scale, and a clinical and sociodemographic questionnaire were administered online. Confirmatory factor analysis (CFA) was used to assess the factor structure of the SCI. Measurement equivalence testing was conducted using Multiple Group Confirmatory Factor Analysis, testing configural, metric, scalar, and strict invariance. For the Italian version of the SCI, reliability and construct validity were also tested.

Results

The SCI factorial structure was confirmed by CFA in the Italian sample. As for measurement equivalence, the Self-care maintenance scale demonstrated full metric and partial scalar invariance, indicating similar cognitive frameworks between US and Italian respondents. The Self-care Monitoring and Self-care Management scales achieved partial metric invariance. Reliability indices were satisfactory: Cronbach’s alpha and Global Reliability Index ranged from 0.69 to 0.84, and test-retest reliability values ranged from 0.70 to 0.84. Construct validity was supported by significant correlations between SCI scales and measures of self-efficacy, positivity, and perceived stress.

Conclusion

The SCI is valid and reliable for measuring self-care behaviours in the Italian population. Measurement equivalence show that SCI can be used cross-culturally and results from Italian and US samples are comparable. Our results support the use of the SCI in national and international self-care research and practice.Keywords: self-care, general adult population, measurement equivalence, validity, reliability.

测量一般成年人的自我照顾：自我照顾量表的交叉验证

自我保健对健康促进、疾病管理和社会公正至关重要。它的测量需要稳健的、基于理论的工具。自我照顾量表（SCI）被开发用来测量成人的自我照顾行为，无论他们的健康状况如何。本研究的目的是测量SCI在意大利样本的效度以及美国和意大利样本的测量等效性。方法采用方便抽样法，招募意大利成年人340人，美国成年人294人。自我护理量表、新一般自我效能量表、积极性量表、感知压力量表以及临床和社会人口学问卷在线进行。采用验证性因子分析（CFA）评估脊髓损伤的因子结构。采用多组验证性因子分析进行测量等效性检验，检验结构、度量、标量和严格不变性。对意大利语版SCI进行了信度和构念效度测试。结果意大利样本经CFA证实了SCI的析因结构。在测量等效性方面，自我护理维持量表表现出完全度量和部分标量不变性，表明美国和意大利受访者的认知框架相似。自我保健监测和自我保健管理量表实现了部分度量不变性。信度指标令人满意：Cronbach’s alpha和Global Reliability Index在0.69 ~ 0.84之间，重测信度值在0.70 ~ 0.84之间。建构效度在SCI量表与自我效能感、积极性和感知压力之间具有显著的相关性。结论SCI测量意大利人群的自我护理行为是有效可靠的。测量等效性表明SCI可以跨文化使用，意大利和美国样本的结果具有可比性。我们的研究结果支持SCI在国内和国际自我护理研究和实践中的应用。关键词：自我保健；普通成人；测量等效性；
