Self-efficacy - the confidence to carry out certain behaviour in order to achieve a specific goal - has increasingly been recognized as an essential prerequisite of effective self-management of chronic diseases. Therefore, valid and reliable measures are needed to evaluate self-efficacy in both research and clinical practice. This study explored the psychometric properties of the German version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale (SES6G).
We performed standardized translation and cultural adaptation of the SES6G into German. The SES6G was externally validated with the German General Self-Efficacy Scale (SWE). Cronbach's alpha, descriptive statistics and principal component analysis were used to assess psychometric properties of the SES6G. We assessed the effect of the number of co-occurring chronic diseases on SES6G scores using linear regression modelling by controlling for age, gender and education level.
We analysed data of 244 primary care patients in Germany. The SES6G showed good convergent construct validity to the SWE (spearman rank correlation 0.578, P < 0.001) and high internal consistency (Cronbach's alpha 0.930). Principal component analysis underlined the one-dimensional structure of the instrument. Adjusted for age and gender, increasing numbers of co-occurring chronic diseases were associated with lower SES6G scores (standardized β-value -0.27, P < 0.001). Education level showed no significant effect.
The SES6G is a reliable and valid instrument to assess patients' self-efficacy for managing chronic diseases. It may enhance further research in German-speaking countries and appears to be a valuable measure for clinical practice.
自我效能感——即执行特定行为以实现特定目标的信心——已逐渐被认为是有效管理慢性病的必要前提。因此，需要有效的、可靠的测量工具来评估研究和临床实践中的自我效能感。本研究旨在探索德国版慢性疾病管理自我效能感 6 项量表（SES6G）的心理测量特性。
我们对 SES6G 进行了标准化翻译和文化调适。SES6G 与德国一般自我效能感量表（SWE）进行了外部验证。使用克朗巴赫α系数、描述性统计和主成分分析来评估 SES6G 的心理测量特性。我们使用线性回归模型评估了同时存在的慢性疾病数量对 SES6G 评分的影响，控制了年龄、性别和教育水平。
我们分析了德国 244 名初级保健患者的数据。SES6G 与 SWE 具有良好的收敛结构效度（斯皮尔曼等级相关系数 0.578，P < 0.001）和较高的内部一致性（克朗巴赫α系数 0.930）。主成分分析强调了该工具的一维结构。在调整年龄和性别后，同时存在的慢性疾病数量与 SES6G 评分较低相关（标准化β值-0.27，P < 0.001）。教育水平无显著影响。
SES6G 是评估患者管理慢性疾病自我效能感的可靠和有效的工具。它可能会促进德语国家的进一步研究，并在临床实践中具有重要价值。
