RESUMEN
The Kentucky Inventory of Mindfulness Skills (KIMS) is a widely used multidimensional tool for assessing the tendency of the individual to be mindful in everyday life. The aim of the present study was to standardize a Greek version of KIMS and to explore its psychometric properties in the Greek population. A sample of 213 Greek undergraduate and postgraduate students from various educational institutions completed the questionnaires. The Mindful Attention and Awareness Scale (MAAS), Toronto Alexithymia Scale (TAS-20), and Perceived Stress Scale (PSS-14) were used to evaluate the criterion validity of KIMS. The Principal component analysis (PCA) resulted in a four-component solution, similar to the structure of the English version of the inventory: "Observing," "Describing," "Acting with awareness," and "Accepting without judgment." All components combined accounted for 45.79% of variance. The subscales had adequate internal consistency, and their scores were correlated with MAAS, TAS, and PSS scores, indicating satisfying criterion validity. Associations between the "Observing" subscale and demographic characteristics were also revealed. This version of KIMS can be safely utilized for assessing mindfulness skills and the efficacy of mindfulness-based interventions in Greek populations.
