Key points The German version of the Mindfulness Inventory for Sport (MIS-D) demonstrated acceptable psychometric properties, including internal consistency, test-retest reliability, factorial and convergent validity, and measurement invariance across gender and competition type. The authors conclude that the MIS-D is a psychometrically sound instrument for assessing mindfulness skills in German-speaking athletes, while calling for further replication to test invariance in other subgroups.

Abstract

Mindfulness-based training programs are highly established in competitive and recreational sports. One of the best-known approaches is the Mindfulness-Acceptance-Commitment Approach (MAC) by Gardner and Moore), which integrates mindfulness aspects of awareness, non-judgmental attitude, and focus. Based on these aspects, Thienot and colleagues developed and validated an English language sport-specific questionnaire, the so-called Mindfulness Inventory for Sport (MIS), for the assessment of mindfulness skills in athletes. The aim of this study is to psychometrically test a German language version of the MIS (MIS-D). To assess the psychometric properties, the MIS-D was examined in an online survey with an integrated test-retest design (n = 228) for reliability (internal consistency; test-retest reliability), validity (factorial; convergent), and measurement invariance (gender; competition type). The present results support the psychometric quality of the German language version of the MIS. Necessary replications should among others focus on checking the measurement invariance for further relevant subgroups.
