• Testing a 20-item version of the German-language K-DOCS • Data from five samples (N = 2,144) were analyzed • Five-factor structure is retained in the short version • Scalar measurement invariance regarding gender • Validity correlations are comparable with the standard form The Kaufman Domains of Creativity Scale (K-DOCS) is a standard self-report instrument for the assessment of creativity. The original K-DOCS comprises 50 items that assess five domains of creativity and it is available in numerous languages, including a German-language version. Recently, a 20-item short form of the K-DOCS, assessing each domain with four items, was introduced, and we evaluate the psychometric properties and structural validity of this proposed short form in the German-language version. We re-analyzed data from three samples and provide new data from two additional samples ( N total = 2,144). We used confirmatory factor analyses and measurement invariance analyses, which showed that (a) the factorial structure of the original version can be retained and (b) invariance was found regarding gender and presentation mode (i.e., presenting the 20-item subset or the full 50 item set). The internal consistencies were in line with expectations for brief measures, with αs ≥ .64 and ωs ≥ .63. Finally, there were only minor changes in the pattern of correlations with external measures when using the short version (≤ .15). Overall, our findings support the usage of the 20-item short version of the K-DOCS, with the typical limitations and benefits associated with brief measures. The K-DOCS-20 is useful in large-scale surveys or repeated-measures designs with limited testing time.
