Psychometric properties of Persian version of five facets of mindfulness questionnaire

Many tools have been designed to measure mindfulness. Five Facets of Mindfulness Questionnaire (FFMQ) is one of the most widely used tools. This study was done to investigate psychometric properties FFMQ in Iranian students.

FFMQ was translated into Persian and administered in 571 students of Shahid Beheshti University of Medical Sciences and Tehran University of Medical Science. Samples were selected using convenience sampling method. A battery including Difficulty in Emotion Regulation Scale (DERS), Emotion Regulation Questionnaire (ERQ), Spielberger's Trait Anxiety Questionnaire, and Affect Control Scales was used in studies for examining divergent, convergent, and discriminant validity. Data were analyzed using Cronbach's alpha, test-retest reliability, and confirmatory factor analysis.

Results of this study supported the five-factor structure of FFMQ (root mean square error of approximation = 0.06, Comparative Fit Index = 0.81 Goodness of Fit Index = 0.91, and Normed Fit Index = 0.87). There was a significantly negative correlation between the FFMQ with DERS, Trait Anxiety, Affect Control, suppression sub-scale of ERQ, and there was a positive correlation with reappraisal subscale of ERQ. The Cronbach's alpha for the FFMQ was. 78.

FFMQ have good psychometric properties in Iranian student sample, and it can be used in studies on student populations.
