Objective: The VASE-(M)HC is an instrument to evaluate Motivational Interviewing (MI) skills. We adjusted the previous version for use in the broader (mental) healthcare context, incorporated new MI insights, expanded the scoring system and created a parallel version. Feasibility and validity evidence in the general practice setting was explored. Methods: The teaching staff of the GP specialty-training, GP-, and PN-trainees (N = 156) completed the VASE-(M)HC. In this mixed-methods study, we examined psychometric characteristics, compared parallel versions, and interviewed assessors. Results: Our adjustments enable assessment of a wider range of MI skills, and allow differentiation of basic and advanced skills. Inter-rater reliability was excellent and internal consistency of the total scale was good for both versions. The parallel versions are comparable in terms of difficulty. Conclusion: The VASE-(M)HC is improved by our revisions and adds multiple advantages to the domain of available MI assessment tools. Practice implications: Due to the adjustments, the instrument can be used in the GP setting (instead of sole focus on substance abuse). The parallel version is useful for research (pretest/posttest) and selective assessment (retake of a test). It is promising to further explore its applicability in the broader (mental) healthcare context and as training material.
