This study aims to develop and test the mindfulness measurement instrument of Buddhist employees. The quantitative approach was applied to this study. The research population was defined as the Buddhist employees in Thai organizations. The research sample was divided into two groups for different purposes. One group consisted of 100 Buddhist employees, of which 50 were meditators and the rest weren’t. This group was engaged in the instrument development phase. The second group comprised 509 participants and was used in testing the reliability and validity of the instrument. The data was gathered using questionnaires. The collected data was compiled and analyzed by computer programs. The statistics employed in the instrumental development process were: Item Congruence Index (IOC), Reliability, and Discriminant analysis, while Confirmatory Factor Analysis (CFA) was used to confirm the validity of the instrument construct. The analysis showed validity of the mindfulness measurement model according to the conceptual framework whereby 34 items of four-factor mindfulness measures: mindfulness of body, mindfulness of feelings, mindfulness of mind, and mindfulness of mind-object were psychometrically sound and conceptually supported the self-assessment of mindfulness for Thai Buddhist employees. This mindfulness scale is thus likely to provide future organizational researchers with a valuable tool for assessing mindfulness practice, and human resources development professionals with a reliable and valid instrument that can aid them in their development of individual training programs for employees.
