OBJECTIVE: 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). METHODS: 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. RESULTS: 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 beta-value -0.27, P < 0.001). Education level showed no significant effect. CONCLUSIONS: 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.
