Self-efficacy is an important factor in the acquisition of self-management skills in patients with chronic diseases. The present study provides a translation and cultural adaptation for the Portuguese population, as well as psychometric properties, of the Self-Efficacy for Managing Chronic Disease 6-Item Scale.
This is a cross-sectional study. As a first stage, a translation and cultural adaptation were conducted. After preparation, a final version was applied initially to a sample of 30 participants with chronic disease in two phases, with a one-week gap between phases, to assess teste retest reliability. Subsequently, a sample of 217 participants with chronic disease, mean age 42.8 (10.7) years, participated in the study. Participants were supposed to be over the age of 18 and with at least one clinically diagnosed chronic disease. The questionnaire was applied electronically.
The results showed a good test retest reliability (ICC of 0.83, 95% CI: 0.65 - 0.92). Internal consistency met the criterion for a reliable measure (global Cronbach's alpha of 0.95). Item-total correlations of all items were above 0.30. A correlation matrix was considered favorable (KMO = 0.90; Bartlett's sphericity test = 1399.090, p < 0.01). The results confirmed the permanence of the 6 items, as in the original scale.
A Self-Efficacy for Managing Chronic Disease 6-Item Scale is a reliable and valid instrument to assess the patients' self-efficacy for managing chronic diseases in Portuguese, enabling its use in clinical practice and in future studies.
自我效能感是慢性病患者获得自我管理技能的一个重要因素。本研究提供了葡萄牙语人群的翻译和文化适应性，以及 6 项慢性病管理自我效能感量表的心理测量学特性。
这是一项横断面研究。首先进行了翻译和文化适应。准备完成后，初步对 30 名慢性病患者进行了最终版本的测试，在两个阶段之间间隔一周，以评估测试重测信度。随后，217 名患有慢性病的参与者参加了研究，平均年龄为 42.8（10.7）岁。参与者被要求年龄在 18 岁以上，且至少有一种临床诊断的慢性病。问卷以电子方式应用。
结果显示，测试重测信度良好（ICC 为 0.83，95%CI：0.65-0.92）。内部一致性符合可靠测量的标准（总 Cronbach's alpha 为 0.95）。所有项目的项目-总分相关性均高于 0.30。认为相关矩阵是有利的（KMO = 0.90；Bartlett 的球形检验= 1399.090，p < 0.01）。结果证实了原始量表中 6 个项目的稳定性。
6 项慢性病管理自我效能感量表是一种可靠和有效的评估葡萄牙语慢性病患者自我效能感的工具，可用于临床实践和未来的研究。
