The Study of Reliability and Validity of the Korean Version of the Toronto Mindfulness Scale

Objectives In this study, we examined the reliability and validity of the Korean version of the Toronto Mindfulness Scale (K-TMS), a brief self-report measure to assess state mindfulness. MethodsZZWe administered the K-TMS, Beck Depression Inventory, Experiences Questionnaire (K-EQ), Mindfulness Attention Awareness Scale (MAAS), Positive Affect and Negative Affect Schedule (PANAS), and Rumination-Reflection Questionnaire (RRQ) to 205 university students and conducted exploratory factor analyses (EFA), confirmatory factor analyses, and correlation analyses among the related variables. Results The K-TMS demonstrated high internal consistency, and its corrected item-total correlations ranged from .37 to .73. Exploratory factor analyses resulted in a two-factor solution (curiosity, de-centering), based on an examination of the scree plot and eigenvalues, which was structurally similar to the original TMS scale. Confirmatory factor analyses indicated that a correlated 2-factor model, with correlated error terms, showed an adequate fit to the data. The K-TMS was positively correlated with de-centering (r=.304, p<.01), as measured by the EQ, with reflective self-awareness (r=.334, p<.01), as assessed by the K-RRQ, and with positive affect (r=.302, p<.01), as assessed by he PANAS. There were no significant relationships between the K-TMS and depression, and the correlation between the K-TMS and the MAAS was not significant. Conclusion These results show the K-TMS is a promising measure of mindfulness state, with good psychometric properties. Further study of the relationship between the K-TMS and mental health is needed.
