An investigation of the validity and reliability of psychometric characteristics of five facet mindfulness questionnaire in Iranian non-clinical samples

Abstract

Introduction: Mindfulness has been an area of increasing interest and research to psychologists during recent decades. Considering the importance of this construct, authors have been striving to make an evaluating questionnaire. The purpose of the present study was to investigate validity and reliability of the Five Facet Mindfulness Questionnaire (FFMQ) through Iranian non-clinical samples.Method: 435 students of Shahed University participated in this study. To calculate the reliability, internal consistency and test- retest were used. To calculate the validity, Neo-FFI (Costa & Mccrae, 1992), Emotion Intelligence Questionnaire (1992), Well-being Questionnaire (Tabasi, 2004), and the Scl-25 (Najarian & Davoodi, 2001) were used. The questionnaires were selected in terms of literature and the relationship between their concepts and mindfulness.Result: Results show good reliability (α = .55-.83), adequate convergent and discriminate validity as for Five Facet Mindfulness Questionnaire in Iranian non-clinical samples. Results also suggest positive correlation between mindfulness and a number number of 5 personality factors, emotional intelligence, well-being and psychological symptoms plus negative correlation with other factors. Results show that we can use the Five Facet Mindfulness Questionnaire for other Iranian non-clinical research samples.Conclusion: Given the much research support for the findings of the present study and the confirmed validity and reliablelity, Accordingly FFMQ can be utilized for measuring mindfulness in the Iranian sample.
